Abstract

The invention provides a machine tool, and belongs to the technical field of machinery. The problems that machining precision is prone to be reduced and stability becomes poor after an existing machine tool is used for a long time are solved. The machine tool comprises a main shaft and a rotary disc, wherein the main shaft comprises a cylindrical main body and an end cover provided with a plurality of connecting holes; the end cover is fixedly connected with the rotary disc through first fasteners penetrating through the connecting holes, and the main body and the end cover are arranged in a split mode; the end cover is provided with a plurality of installation holes which penetrate through the end cover and are arranged in a circumferential direction, and the end cover and the main body are connected through threaded fasteners penetrating through the installation holes; the end cover is further provided with a plurality of positioning pin holes which penetrate through the end cover and are arranged in the circumferential direction, and positioning pins used for positioning the main body and the end cover are installed in the positioning pin holes; and the installation holes and the positioning pin holes are shielded by the rotary disc, so that the corresponding threaded fasteners and the corresponding positioning pins are limited in the installation holes or the positioning pin holes. The machine tool is good in stability, and the machining precision of workpieces in the long-term use process is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a machine tool. Background technique [0002] During the processing of the same workpiece, it needs to go through multiple processes, and it is completed by multiple general-purpose machine tools, such as special tapping machine tools, special reaming machine tools, etc. In each processing procedure, the workpiece to be processed needs to be clamped and calibrated. In this way, the machining accuracy of the workpiece cannot be well guaranteed after multiple clamping, which is not only time-consuming and laborious, but also makes the production efficiency low. [0003] The waterwheel machine tool can realize multi-process processing on the same workpiece, which solves the above problems well. It includes a bed body, a main shaft pierced on the bed body, and an auxiliary disc located in the bed body. The auxiliary disc is fixed on the main shaft, and a turntable is attached to and ...
