Due to its unique operational flexibility, it has been widely used in the field of industrial assembly. In the production and manufacturing of modern high-end devices, a robotic arm bracket is often used to fix the robotic arm. However, the current robotic arm bracket is often very cumbersome to fix the robotic arm, and it is impossible to position the robotic arm, which does not meet the standards required for production and manufacturing.

By fixing a slide cylinder at the output end of the hydraulic push rod, and then providing a buffer spring inside the slide cylinder, when the clamping force is too large, the buffer spring can be compressed for buffering, and such a structure allows the device to clamp the mechanical arm without causing the clamping claw to scratch the surface of the mechanical arm due to the excessive clamping force, and by connecting and fixing the anti-skid layer on the surface of the bracket, the friction between the mechanical arm and the bracket becomes larger, which is more conducive to the fixation of the mechanical arm.

[0011] By rotating the clamping device at the upper end of the clamping claw, the first rotating block and the second rotating block are rotationally connected, so that when the holding device contacts the surface of the robotic arm, the rack pushes the second rotating block to rotate. With such a structure, the second rotating block can be fixed to the upper surface of the robotic arm, so that the device fixes the robotic arm more firmly, and a compression spring is connected and fixed to the bottom end of the rack, so that when the clamping device is separated from the surface of the robotic arm, the compression spring pushes the rack to slide outward, restoring the holding device to its original state. With such a structure, the disassembly of the robotic arm is more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The clamping device 16 includes a first rotating block 161, which is rotatably connected to the top of the clamping claw 6. A blind hole is provided on the first rotating block 161, and a rack 165 is slidably connected in the blind hole.

[0026] Specific implementation: Place the robot arm on the bracket 5, start the hydraulic push rod 11, so that the output end of the hydraulic push rod 11 pulls the slide 121 to move downward, and the buffer spring 123 pulls the push rod 13 upward to move downward, so that the moving block 14 moves downward, thereby driving the pull rod 15 to rotate, and the pull rod 15 drives the clamping claw 6 to rotate.

At the same time, the downward movement of the slide 121 increases the pressure, thereby The push rod 13 stops moving, and the slide cylinder 121 pulls the protrusion 124 downward. The protrusion 124 moves downward to compress the buffer spring 123.
