Description

Technical Field

[0001] The utility model relates to the technical field of precision hardware processing, in particular to a welding tooling for positioning columns of the rear cover of an explosion-proof cylinder machine. Background Technique

Such electric pressing is slower than pneumatic pressing, resulting in low production efficiency. At the same time, they are mostly fixedly arranged and are not convenient to select and adjust according to the assembly situation of the workpieces. Therefore, a welding tooling for positioning columns of the rear cover of an explosion-proof cylinder machine is proposed. Content of the Utility Model

The spherical roller bearing and the tapered roller bearing can not only adjust the rotation angle of the workpiece, but also bear axial and radial loads, and can also press the welding shaft in place, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A welding tooling for positioning columns of the rear cover of an explosion-proof cylinder machine, including a base and a punch limit inner seat;

[0006] Wherein, it further includes a tapered roller bearing and a workpiece limit seat. The tapered roller bearing is fixed inside a groove on the top surface of the base. A workpiece limit seat is installed inside the tapered roller bearing. The input end of the cylinder is electrically connected to the output end of an external controller.

[0007] First, place the workpiece on the top surface of the workpiece limit seat. Insert the welding shaft into the inside of the punch limit bottom plate. Start the cylinder to drive the punch limit inner seat to press down by the piston rod to press the welding shaft into the workpiece, so as to facilitate subsequent processing. The spherical roller bearing and the tapered roller bearing can not only adjust the rotation angle of the workpiece, but also bear axial and radial loads, and can also press the welding shaft in place.

[0008] Furthermore, it also includes a punch limit outer seat, an outer frame and a smooth shaft. The punch limit outer seat is fixedly installed on the bottom surface of the smooth shaft fixing seat. There are two smooth shafts and they are respectively fixed on both sides of the bottom surface of the smooth shaft fixing seat.
