Abstract

The invention discloses a displacement compensation type multi-spindle machining center. The displacement compensation type multi-spindle machining center comprises a main base, a main stand column, asaddle, a workbench and at least two spindle machining units, the stand column is fixed to the main base, the spindle machining units are connected to the stand column in a sliding mode, and a Z-axisdriving device is arranged between the spindle machining units and the stand column. The main shaft machining unit comprises a main shaft and a unit body, the main shaft is installed on the unit body, an X-axis direction displacement compensation mechanism is arranged between the main shaft machining unit and the main stand column and comprises a unit base plate, a guide rail and a motor, the guide rail is arranged on the unit base plate, and the unit body is connected to the guide rail in a sliding mode, and a transmission mechanism is connected between the motor and the unit main body. Micro-motion compensation can be carried out on fine deflection of all machining points on the workpiece in the X-axis direction.

Description

technical field [0001] The invention relates to a numerical control machining equipment, more specifically, it relates to a displacement compensation type multi-spindle machining center. Background technique [0002] The working method of a conventional machining center is that the saddle and the table move up and down in the X-axis direction and in the front-back direction in the Y-axis direction to set the position of the workpiece on the table on the horizontal plane, and the spindle processing unit moves up and down in 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, due to thermal deformation and other factors, the positi...
