Description

Technical Field

[0001] The utility model relates to the technical field of ram structures, in particular to a ram guide rail structure for a vertical lathe. Background Art

[0002] The machine tool spindle is the direct carrier for installing the tool. The spindle is installed on the machine tool slide, and the machine tool slide is installed on the slide saddle. They are direct components for the operation of the machine tool Z axis. During machine tool processing, the spindle drives the tool to rotate and cut, and the tool transmits the cutting torque and feed force to the spindle.

[0003] In the current gantry machine tool design, the crossbeam is equipped with a ram that can move flexibly in the vertical direction to support various processing operations. However, the movement between the crossbeam and the ram usually relies on the guide rail slider mechanism, which is currently mostly fixed, which limits the ability to fine-tune its position. Therefore, when installing the ram, due to the tiny gap that may appear between the guide rail slider and the ram, the two cannot fit tightly, resulting in shaking during the processing, which seriously affects the processing accuracy and product quality.

[0004] Therefore, a ram guide rail structure for a vertical lathe is needed to solve the above problems. Utility Model Content
