Description

Technical Field

[0002] The main structure of a double-column vertical lathe includes components such as the headstock, slide, crossbeam, worktable, and tool post. These components work together to enable the lathe to stably and accurately complete the machining tasks of various workpieces.

[0003] For example, patent CN220347734U discloses a crossbeam slide of a CNC double-column vertical lathe, including a lathe platform, slide rails, connecting structure, sliding plate, limiting structure, driving structure and lathe double columns. The upper surface of the lathe platform is provided with several sets of threaded holes, and two sets of slide rails are provided on the upper surface of the lathe platform. The slide rails have an "I" shaped cross section, and several sets of connecting structures are provided on the lower surface of the slide rails.

[0004] With the above configuration, the existing utility model, by incorporating a slide rail, a limiting structure, a driving structure, and a rack, allows the servo motor's power output to rotate, driving the gear to rotate. When the gear rotates, it meshes with the rack, causing the servo motor to drive the sliding plate along the slide rail. This facilitates positional movement. During the sliding plate's movement, the sliding wheels in the limiting structures on both sides of the slide rail slide against the outer surface of the slide rail, ensuring stable sliding and effectively improving the lathe's machining accuracy. However, the existing vertical lathe's beam slide has the following drawbacks during operation:

[0005] After a period of use, the gears and racks of the above-mentioned device will experience some wear during meshing, requiring the replacement of the slide rail. However, when replacing the slide rail, it is necessary to first use external tools to disassemble the second fixing bolts in sequence before the slide rail can be replaced. This process is not only slow but also laborious, thus affecting the working efficiency of the lathe. Utility Model Content
