[0003] In the prior art, when the brake support plate is pressed, the support stability of the brake support plate is poor and the clamping efficiency is low, which increases the labor intensity of the workers. Therefore, we have introduced a support plate pressing and welding fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a support plate clamping welding fixture, which facilitates the rapid clamping of the brake support plate, resulting in high stability of the clamped brake support plate and reducing the labor intensity of workers, thereby solving the problems mentioned in the background art.

[0006] A support plate clamping welding fixture includes a base, a housing fixedly mounted on the upper end of the base, a hollow tube fixedly mounted on the side wall of the housing, one end of the hollow tube penetrating into the housing and closed, a movable tube slidably mounted inside the hollow tube, one end of the movable tube extending to the outside of the hollow tube and equipped with a first pushing mechanism, the other end of the movable tube being equipped with a first limiting mechanism, a moving rod slidably mounted inside the movable tube, both ends of the moving rod extending to the outside of the movable tube, one end of the moving rod extending to the outside of the hollow tube and equipped with a second pushing mechanism, and the end of the moving rod located inside the hollow tube being equipped with a second limiting mechanism.

[0007] As a further embodiment of this utility model, the first pushing mechanism includes a first cylinder, which is fixedly disposed on the outside of the housing. An annular plate is fixedly disposed at one end of the movable tube outside the hollow tube, and the piston rod of the first cylinder is fixedly connected to the annular plate.

[0008] As a further embodiment of this utility model, the first limiting mechanism includes two push rods, which are respectively fixedly installed on the upper and lower sides of the movable tube. The hollow tube is provided with a strip hole that cooperates with the push rod, and one end of the push rod passes through the strip hole and is fixedly provided with a clamping plate.

[0009] As a further embodiment of this utility model, the second pushing mechanism includes a second cylinder, which is fixedly disposed on the outside of the housing, and the piston rod of the second cylinder is fixedly connected to the moving rod.

[0010] As a further embodiment of this utility model, the second limiting mechanism includes a rectangular rod, and rectangular holes are provided on both the upper and lower sides of the hollow tube. The rectangular rod is slidably disposed in the rectangular holes, and both the upper and lower ends of the rectangular rod extend to the outside of the rectangular holes. Guide blocks are fixedly provided at the opposite ends of the two rectangular rods. A spring is provided between the rectangular rod and the guide block, and a limiting block is fixedly provided at the end of the rectangular rod outside the hollow tube.

Activating the second cylinder causes its piston rod to push the moving rod, which in turn pushes the inclined surface of the guide block, causing the guide block to move to both sides. The guide block compresses the spring, and through the rectangular rod, pushes the limiting blocks. The horizontal part of the limiting block abuts against the inner wall of the brake support plate. At this point, activating the first cylinder causes its piston rod to push the annular plate. The annular plate, through the movable tube and push rod, drives the clamping plate to push the brake support plate. When the brake support plate abuts against the vertical part of the limiting block, the clamping plate and the vertical part of the limiting block are pressed tightly against the brake support plate. This clamping process is complete, facilitating rapid clamping of the brake support plate. The brake support plate is clamped with high stability, reducing the labor intensity of the workers.
