[0002] The electric welder based on the suspension structure is a welding tool that integrates the welding host, welding head and control system into one device. It is installed on the automobile manufacturing production line or workstation through a suspension device, and the welding position can be flexibly adjusted to meet various welding needs. By combining with robot welding technology, this equipment will further improve the automation level of the production line and meet more complex welding needs.

[0003] When the electric welding machine based on the suspension structure is working, oxides are easily attached to its welding head, which affects the quality of welding. There are three existing ways to clean the welding head: grinding wheel cleaning method, chemical washing method and scraper cleaning method; among them, the chemical washing method causes the least damage to the welding head, and the oxides are dissolved by cleaning liquid, and then mechanical cleaning or water flushing are used to completely remove them; due to the stacking of oxides on the welding head, the outermost oxide is easy to clean, but it will block the stubborn oxides below it, reducing the area of ​​contact between it and the cleaning liquid, making it difficult to efficiently clean the stubborn oxides on the welding head; at the same time, after the cleaning liquid on the welding head is rinsed off with clean water, the residual moisture on its surface fails to dry in time, which easily causes corrosion to the welding head. Summary of the invention

[0043] Working principle: When the present invention is used, first, after completing the welding of the parts, the extended end of the push-pull cylinder 612 is controlled to extend to half the length, and the connecting plate 6011 cooperates with the thrust spring to drive the cleaning box 602 to move so that it is located directly below the welding machine body 11. At this time, the baffle 613 contacts the inner wall of the moving cavity 614, and then the angle of the welding machine body 11 is manually adjusted so that the first welding head 3 and the second welding head 4 are located in the cleaning box 602. Then the extended end of the push-pull cylinder 612 is controlled to extend to the longest. Since the baffle 613 contacts the inner wall of the moving cavity 614, the position of the cleaning box 602 does not change, the thrust spring contracts, and the limit rod 60 is driven by the connecting plate 6011. 15 limits the position of the first welding head 3 to prevent it from turning over and resetting. At this time, the position of the flushing tube 6013 changes relative to the cleaning box 602, so that the two openings of the flushing tube 6013 correspond to the positions of the first welding head 3 and the second welding head 4 respectively; and in the process of welding the parts with the first welding head 3 and the second welding head 4, by opening the pump body 609, a sufficient amount of cleaning liquid in the liquid storage tank 608 is injected into the heating barrel 617, and the pump body 609 is closed in time and then a plurality of electric heating rods are opened to heat the cleaning liquid to the set temperature. At this time, the liquid inlet valve is in a closed state, and the air pressure in the heating barrel 617 increases, causing the bladder 610 to expand and become larger. By opening the liquid inlet valve, the air pressure in the heating barrel 617 becomes smaller, so that The cleaning liquid that has reached the set temperature is sprayed out from the two openings of the flushing tube 6013 to flush the first welding head 3 and the second welding head 4, and clean the easily cleaned oxides on the surfaces of the first welding head 3 and the second welding head 4. At this time, the water inlet valve and the drain valve are both in a closed state, so that the cleaning liquid in the cleaning box 602 accumulates and soaks the first welding head 3 and the second welding head 4, thereby cleaning the stubborn oxides on the first welding head 3 and the second welding head 4. In this process, the extended end of the lifting cylinder 503 is controlled to extend. Due to the influence of gravity, the electric heating net 507 extends into the cleaning box 602. The electric heating net 507 is turned on to heat and keep the cleaning liquid in the cleaning box 602 warm to prevent the cleaning liquid from soaking the first welding head 3 and the second welding head 4, the temperature drops and the efficiency of cleaning the stubborn oxide is reduced; after the immersion is completed, the water inlet valve and the drain valve are opened in sequence, so that the clean water in the water tank 10 can flush the residual cleaning agent on the first welding head 3, the second welding head 4 and the electric heating net 507, and the water inlet valve is closed, and the extended end of the lifting cylinder 503 is controlled to shrink and reset, so that the electric heating net 507 is reset, and then the extended end of the push-pull cylinder 612 is controlled to shrink and reset, so that the first welding head 3 and the second welding head 4 are reset, and the blower 505 is turned on, so that the airflow blown out from the L-shaped tube 506 passes through the electric heating net 507, and the hot airflow generated heats and dries the first welding head 3 and the second welding head 4 to avoid corrosion thereto.
