Description

Technical Field

[0001] The present invention relates to the technical field of machining, and specifically to a production device for the ram of a high-precision CNC gantry machining center. Background Art

[0002] The ram is the main component for position adjustment and movement of a CNC gantry machining center. The tool holder is fixed on the ram, and the precise adjustment of the machining position is achieved through the sliding of the ram. During the use of the ram, due to long-term use or improper operation and impact, the phenomenon of groove bending of the ram will occur. After the groove is bent, it cannot move smoothly normally, which seriously affects the production and processing quality of the CNC gantry. However, the ram is relatively large in volume and mostly made of metal materials. Throwing away the bent and scrapped ram directly for replacement is extremely wasteful.

[0003] Those skilled in the art propose a tooling that can clamp the ram by its own weight according to the above technical problems. While facilitating the clamping and machining of the ram, it can also support the groove of the bent ram, facilitating the correction of the ram by mechanical means and effectively preventing the collapse of the groove during the correction process.
