[0014] The present invention provides a valve core suspension welding positioning device for an EGR valve, which has the following beneficial effects: 1. The valve core suspension welding positioning device of the EGR valve is designed with a composite mechanism. By placing the valve core on the inner side of the clamping mechanism, the valve core is clamped and fixed by the clamping mechanism to prevent displacement during welding, avoid dislocation of welding points during welding, make welding points unsightly and have poor welding effect. The clamping range can be adjusted by the clamping mechanism to expand the use range of components and improve the applicability of the equipment. After the clamping mechanism is fixed, the electric push rod controls the docking mechanism to descend, docks with the clamping mechanism to press the top of the valve core, so as to ensure the stability during welding. The central shaft is driven to rotate by the motor, and the clamping mechanism is driven to rotate, so as to maintain uniform welding speed during welding, thereby improving welding quality, welding speed and efficiency, and welding accuracy.

In the process of the hydraulic block sliding toward the valve core, the square plate is contacted with the surface of the valve core, and the spring rod is squeezed by the reaction of the valve core surface to play a role in buffering and shock absorption. In the process of clamping, the valve core is protected to a certain extent to prevent excessive pressure from causing bumps or wear on the surface of the valve core, thereby affecting the quality of the valve core. The pressure on the surface of the valve core is reduced by the spring structure, and the wear of both is reduced, thereby extending the service life of the components. Secondly, the soft rubber pad has the effect of wear resistance and buffering, further reducing the wear on the surface of the valve core, while increasing the friction on the surface of the valve core, and improving the fixing and stabilizing effect.

[0016] 3. The valve core suspension welding positioning equipment of the EGR valve is designed with a docking mechanism. When the top of the valve core penetrates into the inside of the docking shell, gas is injected into the inside of the airbag bag through the square shell, so that the inside of the airbag bag is filled with gas and expanded, causing compression on the surface of the component, thereby achieving the fixing effect of the component, improving the stability of the component, and preventing shaking. At the same time, the airbag bag has a certain toughness and can be deformed according to the shape of the clamped object, thereby increasing the clamping range and achieving a better fitting effect. The silicone plate is made of silicone material and has a certain toughness and wear resistance. When the silicone plate clamps the valve core with the airbag bag, the protective effect of the airbag bag is achieved, and the surface wear of the component caused by excessive clamping force is avoided, and the surface of the airbag bag is prevented from being damaged, affecting the operating efficiency of the equipment.

The funnel plate plays a role in guiding the gas flow. The funnel plate diameter is reduced by a short tube to improve the flow effect of the gas, improve the work efficiency, and facilitate subsequent operations.

By placing the valve core on the inner side of the clamping mechanism 15, the valve core is clamped and fixed by the clamping mechanism 15 to prevent it from shifting during the welding process, avoiding the welding point from being misaligned during the welding process, making the welding point unsightly and the welding effect poor. The clamping range can be adjusted by the clamping mechanism 15 to expand the use range of the component and improve the applicability of the equipment. After the clamping mechanism 15 is fixed, the electric push rod 14 controls the docking mechanism 16 to descend, docks with the clamping mechanism 15, and presses the top of the valve core to ensure stability during welding.

When the top of the valve core penetrates into the inside of the docking shell 161, gas is injected into the inside of the air bag 163 through the square shell 162, so that the inside of the air bag 163 is filled with gas and expands, causing compression on the surface of the component, thereby achieving a fixing effect on the component, improving the stability of the component, and preventing shaking. At the same time, the air bag 163 has a certain toughness and can be deformed according to the shape of the clamped object, thereby increasing the clamping range and achieving a better fitting effect.

The diamond block 1664 adopts a diamond structure, thereby increasing the contact area with the surface of the valve core and improving the anti-slip effect.

[0029] The third embodiment is based on the first and second embodiments.

In the process of welding, harmful gases are easily generated, which are easy to affect the human body. The fan 205 generates wind force, and the gas is sucked into the inner side of the processing shell 201 from one side of the funnel plate 202, and at the same time, some debris is driven in to prevent the debris from affecting the subsequent welding. The funnel plate 202 plays a role in guiding the flow of gas, and the diameter of the funnel plate 202 is reduced by the short tube 204, so as to improve the flow effect of the gas, improve the operation efficiency, and facilitate the subsequent operation.

The rotating block 2112 is driven to rotate by wind force, and the scraper 2114 increases the contact area with the gas, thereby increasing the rotation effect, so that the scraper 2114 rubs against the inner wall of the equipment, thereby achieving the cleaning effect of the inner wall dust, preventing excessive accumulation of dust, thereby affecting the subsequent ventilation effect, and avoiding affecting the normal operation of the equipment. By opening the strip groove 2115, the contact area is increased by grooving, and the cleaning effect is improved. Secondly, the chip removal effect is enhanced by grooving, and the debris adhesion is avoided, which prevents the subsequent friction effect from being affected.

[0032] When in use, the staff places the valve core on the inner side of the clamping mechanism 15 inside the composite mechanism 1, and the clamping mechanism 15 plays a role of fixing and clamping the object to keep the valve core upright. Secondly, the electric push rod 14 controls the docking mechanism 16 to move to one side of the clamping mechanism 15, so that the docking mechanism 16 is fixed from the top of the valve core. A buffer mechanism 166 is arranged inside the docking mechanism 16. The buffer mechanism 166 reduces the impact force generated by the downward pressure on the surface of the valve core to prevent excessive downward pressure from damaging the surface of the object, thereby affecting the welding effect of the components. Then, gas is injected into the airbag 163 to expand the airbag 163 to squeeze the top of the valve core, so as to achieve the squeezing and fixing effect of the object. At the same time, the airbag bag 163 can be adjusted according to the surface shape of the object, so as to improve the clamping application range and clamping effect. After the valve core is fixed, the clamping mechanism 15 is driven to rotate by the motor 4, and then the valve core is welded by the welding gun 19. The welding gun 19 is rotated to perform horizontal uniform speed welding, so as to improve the welding quality, improve the aesthetics and connectivity of the weld, and avoid affecting the welding accuracy. Harmful gases will be generated in the welding process, which will be absorbed by the processing mechanism 2 and then filtered and purified to prevent the gas from scattering and causing harm to the human body. At the same time, the valve core is rotated to absorb the debris generated by the surface welding, so as to achieve the purpose of cleaning the equipment, facilitate subsequent cleaning, and maintain the continuity of the equipment operation.
