The vehicle axle (also called the axle) is connected to the frame through the suspension, and wheels are installed at both ends. The main function is to bear the load of the car and maintain the normal driving of the car on the road. In the production process of axles, the quality of axle welding is related to the safety of automobiles. The axle must not only bear the weight and force, but also bear the larger bending moment and torque caused by the dynamic load and static load. For this reason, the axles are required to have sufficient strength, rigidity and toughness, which puts forward high requirements on the "welding quality" of the axles. Welding is a conventional processing method in modern machinery manufacturing and is widely used in automobile manufacturing; it is also a key link in the manufacture of axles. In the manufacture of axles, welding production has the characteristics of large batches, fast production speed, and high welding accuracy requirements. At present, the production of axles is labor-intensive, the working environment is harsh, the welding quality is not high, and the production flexibility is poor, which cannot meet the needs of modern production. With the continuous deepening of intelligent manufacturing, many axle manufacturing companies have actively introduced flexible automated welding control systems. The welding process of the welding system is more mature and safe, and meets the requirements of the manufacturing precision of automobile axles. Improving the stability and adaptability of the automatic welding production line for axles is of great significance to the production of axles with good quality and high technical content. Among the many welds in the axle welding, the two circumferential welds between the deformed axle tube and the axle housing are particularly critical. They are integrated with the drive axle housing to fix the axial relative positions of the left and right drive wheels, and support the frame and its upper part together. The mass of each assembly can bear the road reaction force and moment transmitted by the wheels when the car is running, and transmit it to the frame through the suspension. The

Automated welding including Automated welding including the automation of welding processes and welding production. The latter includes the automation of the entire welding production process consisting of material preparation, cutting, bevel preparation, workpiece assembly, welding, heat treatment, and welding inspection. Automatic welding equipment mainly includes traditional welding auxiliary machines, welding sensors, central controllers, welding machines, welding fixtures, automatic welding heads, special welding guns, etc. The advancement of automatic welding technology has promoted the development of my country's welding industry. Mechanical welding is an important guarantee for improving welding quality and efficiency. With the application of automatic welding machines, productivity can be further improved. What is the welding seam tracking and welding positioning of the welding robot?  Strictly speaking, the welding seam tracking and positioning system of the welding robot is composed of two parts: before welding(welding finding), the welding seam positioning function checks whether the seam is suitable, and accurately reaches the joint to be welded. Real-time welding seam tracking, product deformation monitoring during welding. Seam tracking It means that an optical sensor is installed before the welding position data is collected, collected by power or welding parameters, and then transmitted to the welding robot and various adaptive fuzzy control algorithms are used for the correct welding robot trajectory or special plane, so as to achieve self-control. Adapt control to realize real-time weld tracking. Welding positioning The process of using one or more searches to determine the position of the weld to be welded by moving the welding robot or editing the machine program path. How to realize the welding seam tracking and positioning of the welding robot?  There are many ways to realize the welding seam tracking and positioning of the welding robot. There are two commonly used ones: peripheral auxiliary detection and self-detection. Peripheral auxiliary detection: laser tracking, photographic imaging tracking. The w

aTiny Laser Displacement Sensor-Help improve the quality of the industry and increase the yield rate of users The laser displacement sensor is a sensor that uses laser technology for measurement, and consists of a laser, a laser detector and a measurement circuit. Laser displacement sensor measurement principle: cylindrical objective lens expands the laser beam into strips, the laser diffuses on the target, the emitted light is imaged on the CMOS, and the displacement and shape are measured by detecting changes in position and shape. Difficulties of laser displacement sensor measurement: (caused by the material and structure of the measured object) ○ Part of the light emitted by the sensor is absorbed by the material, such as rubber and ink cartridges, resulting in a decrease in the intensity of the reflected light. It is necessary to adjust the exposure time of the laser displacement to overcome this problem; ○ The metal products are highly reflective or specularly reflect the object to be measured, causing the light to return vertically, failing to form diffuse reflection, resulting in poor measurement results. The aTiny laser displacement sensor independently researched and developed by【ATINY】 has strong detection ability and stability ○ Support the detection of multiple materials; ○ Anti-high reflection technology can distinguish and eliminate multiple reflections that affect accurate measurement, and then achieve stable measurement under high reflection conditions. The aTiny laser displacement sensor solves the detection quality management problem that is difficult to achieve with traditional contact sensors. Under the same measurement conditions, it reflects the advantages of high quality, low price, and high cost performance! The aTiny small laser displacement sensor does not need to apply external force to the measured object. It is widely used in aerospace, mechanical automation, precision instruments, automotive electronics, due to its high detection frequency, accuracy, and strong environmental adaptability. Railway tracks and other fields. Can be solved: ♢ Measure contour, angle, spacing, etc. ♢ Defect detection, flatness detection, item pos

Those who do technical research can't escape boring and repetition. The more complex the technology, the more basic and simple experiments must be started. First of all, buy a large number of devices with the same performance, and the technicians have to test and screen them one by one. Then, follow the technical system process step by step. During this period, you will still encounter unexpected difficulties, and you need to rely on the professional knowledge of the technicians and the practical experience accumulated over the years to break through. In the end, the staff finally developed a product after all the hard work, but they entered a new technology research and development stage without stopping. In the new stage, technicians have to test, apply, adjust, upgrade, and update products... just like that, technical research is always running. Huawei is one of the best domestic companies in technology, and their technical team is basically the same, doing a lot of testing, doing a lot of technology accumulation, and then summing up a set of their own methodology. As an industrial intelligent laser displacement sensor and industrial big data service provider that integrates R&D, production, sales and service, 【ATINY】  has experienced nearly 10 years of development and has now formed a relatively systematic R&D technology system. Today, we will walk into the technical department of Chuangxiang to explore the story behind the laser displacement sensor. Before talking about the technology, let's first understand the products developed by 【ATINY】  At this stage, the two products that 【ATINY】 will focus on promoting are the special laser displacement sensor for seam tracking and the laser seam tracking system. The former is mainly used in the welding industry, which can realize automatic identification, positioning, and guidance of the welding seam, and cooperate with industrial robots and special welding machines to realize automatic welding, which effectively improves the welding quality and replaces labor. The latter is widely used in automobiles, 3c industries and other industrial production, mainly for key parameter m

Argon arc welding is a welding technique that uses argon as a shielding gas. Also known as argon gas shielded welding. It is to pass argon shielding gas around the arc welding to isolate the air from the welding area and prevent the oxidation of the welding area. The argon arc welding technology is based on the principle of ordinary arc welding. It uses argon gas to protect the metal welding material. Through high current, the welding material is melted into a liquid on the welded substrate to form a molten pool. A welding technology in which the welding material achieves metallurgical bonding. Because the argon gas is continuously supplied during high-temperature fusion welding, the welding material cannot be in contact with oxygen in the air, thereby preventing the oxidation of the welding material, so it can weld stainless steel and iron hardware. . It has the characteristics of heat concentration, fast welding speed and high efficiency, so it is widely used.   Characteristics of argon arc welding 1) The mechanical protection effect is good, the welding quality is excellent, the weld seam is beautifully formed, and there is no slag shell. 2) The arc is stable, the heat-affected zone is small, and the post-welding deformation is small. 3) Adopt gas protection, visible arc, easy to operate, easy to realize all-position welding, easy to automatic control. 4) Argon gas is expensive, and the argon arc welding equipment is complicated and costly.   In actual production applications, argon arc welding has the following problems: Higher requirements for the relative position of the welding torch and the welding seam; For welding seam tracking, in addition to common arc, smoke, spot welding and other interference, there is also strong electromagnetic interference, which has a great impact on some conventional electronic components; Argon arc welding is harmful to the human body. Ultraviolet rays, infrared rays, ozone, carbon dioxide, carbon monoxide gas and metal dust are harmful to welders. Argon arc welding products require high precision due to the small weld seam, and ordinary trackers on the market are powerless. The laser welding seam tracking

Welding monitoring   When observing the welding process, the weld pool monitoring system independently developed by【ATINY】  will move the weld pool monitoring camera at a corresponding uniform speed with the movement of the welding torch to ensure that the camera is aligned with the weld pool and accurately observe the welding process. Welding wire position, molten pool state, posture, etc. It can remotely monitor the arc, welding wire (tungsten electrode), molten pool, weld, base metal, surrounding environment, and the state of slag or bubbles in the molten pool, so as to adjust welding parameters in time, which can greatly improve welding quality and increase welding production efficiency. Realize the visualization of the molten pool and the weld bead, and the state of the welding point, the welding torch, and the position of the weld during the welding process can be clearly displayed through the imaging system. The molten pool monitoring system not only solves the problems of difficult observation and monitoring when welding equipment is working, but also improves the reliability of the welding system. It is suitable for any automatic welding equipment with high compatibility. This not only greatly improves the welding observation environment, but also saves manpower and improves the welding quality and quality. The system has the characteristics of high cost performance, simple setting, convenient operation, etc., and is particularly suitable for integration into existing automation systems.   Hardware parts High-dynamic industrial cameras can remotely capture the welding process in high-definition, and provide multiple data output interfaces.

Recently, the Haidian News, the Haidian District Committee of the Communist Party of China (Issue 4007), Zhongguancun Guide (Issue 632), published an article titled "Smart Eyes Tracking, Precise and Intelligent Manufacturing" on the "Technology·Brand" Special Edition (Issue 632) Article. Reported our company's technical achievements and outstanding contributions in industrial intelligent manufacturing.   The following are published articles: "Smart Eyes" Tracking Precision Intelligent Manufacturing ——【ATINY】 seizes the beach in industrial intelligent manufacturing Our reporter Yu Jingwen In daily life, people often see that welders wear protective equipment and perform welding work between "electric flints". At this time, passing pedestrians usually choose to stay away. The main reason is that the smoke, arc, electromagnetic, splash, poisonous gas, etc. formed during the welding process will cause a certain degree of harm to the human body. In addition, welders are also faced with many dangerous factors such as electric shock, poisoning, fire, explosion, etc. during the welding operation, and the types of welders are therefore listed as high-risk industries. Today, with the rapid development of industrial automation, welders are active in more professional subdivisions, serving high-precision equipment and instruments, and part of the daily work can be completed through assembly lines. In 2016, as Alpha Go defeated the top human players, the wheel of history also began to enter the time of artificial intelligence. The word difference between "manufacturing" and "intelligent manufacturing" has made it difficult for many domestic welding factories to undergo transformation and upgrading. The work of welders requires the cooperation between eye-brain-hands. If you want to realize unmanned intelligent operation, you need to break the technical bottleneck, so that the robot can see, think, and act like a human. This is precisely Industry 4.0. The core: through the "sensing-decision-execution" approach, the intelligent and informatiza
