[0002] In the field of metal processing, welding is a commonly used connection process, which has high requirements for welding quality and efficiency. During the welding process, it is very important to ensure the accurate centering of the workpiece to be welded. Traditional welding machines have many shortcomings in centering operations. For example, some existing welding machines require manual adjustment of the workpiece position during centering, which not only consumes a lot of manpower and time, but also makes it difficult to ensure the accuracy of centering, resulting in unstable welding quality and increased scrap rate. Although some welding machines are equipped with certain centering devices, they are complex in structure, expensive, and difficult to maintain, which is not conducive to large-scale promotion and application. In addition, when faced with metal workpieces of different shapes and sizes, the versatility is poor and cannot meet diverse production needs.

[0003] When existing metal processing welding machines weld material metals, the fixed angles deviate due to the different shapes of the metals, which affects the welding effect. Therefore, a new design was made to address this situation. Summary of the invention

[0013] The present invention provides a metal processing welding machine with an automatic centering function. It has the following beneficial effects: 1. The metal processing welding machine with automatic centering function adopts a composite mechanism design. By placing the material inside the self-centering mechanism, the self-centering mechanism fixes the material to maintain stability during welding. At the same time, the self-centering mechanism can adjust the fixing center when fixing the material, improve the accuracy of material placement, improve the welding effect, and prevent deviation. After the material is fixed, the material is laser welded by the welding gun to achieve the effect of welding the material. The first electric push rod controls the angle of the carrier plate to meet different welding requirements. Before welding, the clamping mechanism slides on the carrier plate to facilitate the fitting of the parts on the object. The material surface is touched to improve the welding accuracy and avoid affecting the welding effect.

Secondly, after a long period of operation, it is easy to cause serious wear of the components, so it is convenient to replace them. When placing the material, it contacts the buffer mechanism, and the buffer mechanism plays a role of shock absorption and buffering, thereby reducing the collision of the components when they are placed and improving the stability of the components.

[0016] Fourth, the metal processing welding machine with automatic centering function is designed with a friction mechanism. The diamond block is inserted into the clamping block to facilitate replacement. When the friction plate is under pressure, the friction plate squeezes the spring to reduce the clamping pressure and improve the stability during clamping. The connecting rod plays an auxiliary connection role to improve the stability of the spring when it contracts. By opening a plate surface incision and opening a groove to increase the contact area, the friction performance is improved, the clamping effect is further improved, and the grooving has a certain anti-slip effect.

Then the driving device 26 controls the clamping block 23 to clamp and fix the material, improves the processing accuracy, automatically centers and positions, and maintains uniform force clamping. After the material is fixed, the motor 4 drives the active gear block 12 to control the self-centering mechanism 2 to rotate, and then the welding gun 18 inside the composite mechanism 1 is used to weld the material, so as to achieve the effect of uniform speed welding, thereby improving the welding quality and preventing deviation in manual welding. A protective mechanism 19 is arranged outside the welding gun 18, and the protective mechanism 19 protects the welding gun 18 to avoid collision when it is attached to the surface of the material, so as to avoid affecting the welding effect. In the process of welding the material, the debris generated in the welding process is absorbed by the processing mechanism 3, so as to clean the impurities outside the equipment and avoid excessive accumulation of impurities to affect the normal operation of the equipment. A rotating mechanism 39 is arranged inside the processing mechanism 3, and the rotating mechanism 39 rotates to rub the inner wall of the processing mechanism 3, so as to clean the impurities on the inner wall of the equipment and avoid accumulation of impurities after long-term operation, which is easy to affect the gas flow effect, so as to maintain the normal operation of the equipment. After the welding is completed, the material is taken out from the inside of the self-centering mechanism 2.
