Description

Refrigerant runner plate brazing welding tool Technical Field The utility model relates to the technical field of processing of parts of new energy automobiles, in particular to a brazing welding tool for a refrigerant flow passage plate. Background The refrigerant flow channel plate for the new energy automobile heat management integrated module adopts a gas shielded brazing welding process, and a product structure of the refrigerant flow channel plate mainly comprises a refrigerant flow channel plate main plate, a refrigerant flow channel plate auxiliary plate, a refrigerant joint and a welding gasket, wherein the refrigerant flow channel plate is an aluminum alloy die casting, a welding surface is formed by machining, the area of a workpiece welding surface is large, the flatness of the welding surface is poor, the refrigerant flow channel plate auxiliary plate adopts a stamping part, the welding surface is poor after the stamping forming due to the fact that the welding surface of the workpiece is large, and the welding gasket adopts the stamping part. The flatness of the welded surface after press forming is poor because the weld pad is thin (only 1 mm). The refrigerant runner plate main plate and the refrigerant runner plate auxiliary plate are welded together through a brazing process, and the refrigerant joint is welded together through a welding gasket and the refrigerant runner plate auxiliary plate through the brazing process. Because the refrigerant flow channel plate is a pipeline of the heat pump system of the new energy automobile, the pressure is higher during working, and the highest working pressure can reach 2.0MPa, the welding quality requirement on the refrigerant flow channel plate is extremely high. Therefore, a tool for brazing and welding the refrigerant flow channel plates needs to be studied, so that the problems of simultaneous welding and forming of various components and compatibility of manufacturing errors among different components can be solved. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provides a brazing welding tool for a refrigerant flow passage plate. The technical scheme includes that the brazing welding tool for the refrigerant flow channel plate comprises a supporting component, wherein the supporting component comprises a supporting frame, a supporting platform is arranged at the upper end of the supporting frame, the brazing welding tool also comprises a pressing component, the pressing component comprises a pressing frame, and pressing columns matched with the supporting platform are arranged on the pressing frame. Further, the supporting platform comprises a plurality of upward supporting columns, a welding bottom plate is arranged between the upper ends of the supporting columns, and the upper end face of the welding bottom plate is matched with the refrigerant flow passage plate. Further, the press fit column is an elastic press fit column, the elastic press fit column comprises a floating rod, the floating rod upwards penetrates through the press fit frame, a buffer spring is arranged between the floating rod and the press fit frame, and a pressure head matched with the refrigerant flow passage plate is arranged at the lower end of the floating rod. Further, the floating rod is provided with an exhaust cavity, and the pressure head is provided with an exhaust hole communicated with the exhaust cavity. Further, be provided with pretension structure between support frame and the pressfitting frame, pretension structure includes the connecting rod, the connecting rod lower extreme is articulated with the support frame, the connecting rod upper end is provided with pressfitting frame matched with horizontal clamp plate. Further, be provided with guide structure between support frame and the pressfitting frame, guide structure is including setting up the guide bar on the pressfitting frame, be provided with on the support frame with guide bar matched with uide bushing. Further, a welding dust cover is further arranged on the pressing frame. The welding device has the beneficial effects that the support assembly and the pressing assembly are arranged, and the refrigerant flow passage plate is pressed onto the support assembly through the pressing assembly, so that the welding device is accurately fixed, and the welding stability is ensured.
