Abstract

The invention discloses a special purpose machine tool machining axial holes of a main shaft. The special purpose machine tool comprises a machine tool body, tools, a hydraulic sliding table hydraulic station, a cooling system and an electric apparatus part, and further comprises a power head and a special clamp device, wherein a plurality of tools rotating simultaneously, and a driving part are arranged on the power head; the special clamp device comprises a positioning part and the driving part; the power head is driven by a motor to change tools automatically to machine the axial holes; two gear plates on the special clamp device work together with a three jaw chuck and a pressing plate to realize clamping and positioning of a workpiece. The special purpose machine tool has the technical effects that four procedures of the machining are fulfilled through clamping in a time; the machining precision and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of metal processing machine tools, in particular to a special machine tool for machining axial holes of a spindle. Background technique [0002] In the process of metal processing, there are situations where one spindle needs to process multiple holes in the axial direction. General processing machine tools need multiple clamping and positioning to complete. There are positioning errors in the process of multiple clamping, which leads to the existence of machining errors. In severe cases, the entire spindle may be scrapped, and multiple clamping also wastes man-hours and reduces productivity. [0003] There is no good solution yet. Contents of the invention [0004] In order to overcome the problems existing in the prior art, the invention provides a machine tool with one-time clamping, small positioning error, high machining accuracy and high production efficiency. [0005] The technical solution adopt...
