Description

Technical Field

[0001] This utility model relates to the field of robot manufacturing technology, and in particular to a machine tool fixture for machining shaft holes of robot supports. Background Technology

[0002] The robot support frame is a key component that supports the overall structure of the robot, ensuring its stability and load-bearing capacity. Its core functions are: to provide stable support, ensuring that the robot maintains structural stability during movement or under load, and to prevent collapse or failure; and to guide joint movement, ensuring flexible movement and coordinated action of the robot joints through a reasonable layout of the support structure.

[0003] In a robot support structure, there is an axial shaft hole and a radial shaft hole. The two shaft holes have high technical requirements in terms of both the surface machining accuracy of the holes and the positional accuracy between them. Therefore, the machining of the shaft holes of the support is a key process to ensure the precise fit of the mechanical components.

[0004] In existing bracket shaft hole machining processes, the bracket is typically mounted on a fixture, positioned and clamped, and then machined using a multi-axis CNC machine tool. However, with the existing fixture structure, the clamping plate cannot be effectively adjusted according to the complex shape of the robot bracket, causing the bracket to shift due to vibrations generated during machining, thus affecting the machining accuracy of the bracket shaft hole.
