Abstract

The invention provides a machine tool, which belongs to the technical field of machinery. It solves the problems that the existing machine tool is easy to reduce the processing accuracy and the stability after being used for a long time. The machine tool includes a main shaft and a turntable. The main shaft includes a cylindrical main body and an end cover with a plurality of connection holes. The end cover and the turntable are fixedly connected by fasteners passing through the connection holes. The cover is provided with a plurality of penetrating and circumferentially arranged installation holes, and the end cover and the main body are connected by threaded fasteners passing through the installation holes. The end cover is also provided with a plurality of penetrating and circumferentially arranged positioning holes. Pin holes, positioning pins for positioning the main body and end caps are installed in the positioning pin holes, and the mounting holes and positioning pin holes are blocked by the turntable so that the corresponding threaded fasteners and corresponding positioning pins are limited in the mounting holes or positioning pin holes . The machine tool has good stability and ensures the machining accuracy of the workpiece during long-term use.

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 ...
