Optical-mechanical structure for vertical machining center

Abstract

The invention discloses an optical-mechanical structure for a vertical machining center. The optical-mechanical structure comprises a lathe bed, a standing column, a carriage, a workbench, a spindle box, a pulley, an X-axis transmission mechanism, a Y-axis transmission mechanism, a Z-axis transmission mechanism and a counterweight balance device. The standing column and the carriage are fixed on the lathe bed. The Z-axis transmission mechanism is mounted on the standing column. The spindle box is slidably disposed on the standing column and in drive connection with the Z-axis transmission mechanism. The pulley is fixed at the top of the standing column. The counterweight balance device is disposed on the standing column and connected with the spindle box through steel wire rope winding on the pulley. The X-axis transmission mechanism is mounted on the lathe bed. The carriage is slidably disposed on a slide rail of the lathe bed and in drive connection with the X-axis transmission mechanism. The Y-axis transmission mechanism is mounted on the carriage. The workbench is slidably disposed on a slide rail of the carriage and in drive connection with the Y-axis transmission mechanism. The Y-axis transmission mechanism is above the X-axis transmission mechanism. The optical-mechanical structure is shake-free and stable in operation, and accordingly machining precision is increased.

Description

technical field [0001] The invention relates to the technical field of vertical machining centers, in particular to an optical-mechanical structure of a vertical machining center. Background technique [0002] With the rapid development of my country's automobile, mold, aviation, aerospace, electronics, plastics, and alloy industries, traditional manual milling machines can no longer meet the needs of processing and manufacturing industries. Although the number of imports of CNC milling machines and machining centers in my country is increasing year by year, they still cannot meet the needs of the domestic processing industry. Therefore, accelerating the development of domestic CNC milling machines and machining centers with high cost performance is the urgent task and key development direction of domestic professional manufacturers. [0003] Although the specifications, performance, usage and price of vertical machining centers at home and abroad are very different, they a...

AI Technical Summary

Problems solved by technology

[0006] However, the optical machine of the existing vertical machining center adopts a cross structure with the X-axis on the top and the Y-axis on the bottom. The size of the base is small, and the size of the saddle is large. The optical machine is easy to shake and unstable when running, which affects the processing accuracy

In addition, the span of the guide rails in the optical-mechanical three-axis direction of this structure is small, resulting in a narrow space inside the base, making it impossible to install drag chains, grating rulers and other components inside the shield

In addition, the existing optical machine generally adopts a single-sided spiral chip removal structure, which cannot remove chips in time, thus affecting the service life of the optical machine
