Abstract

The multi-spindle machining center with the micro-motion compensation function comprises a main base, a main stand column, a saddle, a workbench and at least two spindle machining units, the main stand column is fixed to the main base, the spindle machining units are connected to the main stand column in a sliding mode, and each spindle machining unit comprises a Z-axis driving device, a spindle and a unit body; the spindle machining unit further comprises a micro-motion compensation mechanism, the micro-motion compensation mechanism comprises a base body, a guide rail and a motor, the guide rail is obliquely arranged on the unit body, the unit body is slidably connected to the guide rail, and a transmission mechanism is connected between the motor and the unit body. According to the invention, fine displacement of each processing point on the workpiece in the Y-axis direction can be subjected to micro-motion compensation, the operation is convenient, and the working efficiency is improved.

Description

[0001] This application is a divisional application for the invention patent titled "A Multi-Spindle Machining Center with Micro-Motion Compensation Function"; the application number of the parent application is: CN202010530104.9; the application date of the parent application is: 2020.06 .11. technical field [0002] The invention relates to a numerical control machining equipment, more particularly, to a multi-spindle machining center and system with micro-motion compensation function. Background technique [0003] The working method of the conventional machining center is that the saddle and the table move in the left and right directions of the X axis and the front and rear directions in the Y axis direction. Move, through the rotating spindle to process the surface, groove, hole and other structures. [0004] In order to improve processing efficiency, some machining center manufacturers have introduced multi-spindle machining centers with multiple spindles that can pro...
