Problems solved by technology

However, when processing multiple processing points, due to thermal deformation and other factors, the position on each plane of the workpiece may be slightly displaced, and the relative position of each processing point may also change. Causes deviations in final workpiece machining
The main shaft of the existing machining center is easy to move in the Z-axis and X-axis directions, but it is difficult to move slightly in the Y-axis direction. This is because the internal space of the machining center is extremely limited. The structure will greatly increase the complexity of the structure

Abstract

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

Description

technical field [0001] The invention relates to a numerical control machining equipment, more specifically, it relates to a multi-spindle machining center with micro-motion compensation function. Background technique [0002] The working method of a conventional machining center is that the saddle and the worktable move in the left and right directions of the X-axis direction and the front and rear directions of the Y-axis direction to set the position of the workpiece on the workbench on the horizontal plane, and the spindle processing unit moves in the up and down direction of the Z-axis direction. Move, and process structures such as surfaces, grooves, and holes through the rotating spindle. In order to improve processing efficiency, some machining center manufacturers have introduced multi-spindle machining centers with multiple spindles that can simultaneously process multiple processing points on the same workpiece. However, when processing multiple processing points,...
