Abstract

The invention relates to a numeric control lathe which comprises a machine tool, a working platform and a driving motor of the working platform. The working platform is mounted on the guide rails of the machine tool; a screw rod is arranged in parallel between two guide rails at the bottom of the working platform; one end of the screw rod is fixed by a support saddle, and the other end of the screw rod is connected with the driving motor by an axial clearance adjusting device. The invention has simple structure, the axial clearance and the radial clearance of the screw rod are both limited in the play range of a bearing, the screw rod can work stably, the service performance and the service life of the screw rod are improved, and the processing noise of the lathe is reduced.

Description

technical field [0001] The invention relates to a numerically controlled lathe. Background technique [0002] In the structure of the machine tool, the reciprocating movement of the working table of the machine tool along the guide rail is driven by the rotating screw driving the nut connected to it, and the matching accuracy of the screw and the nut and the axis of the screw and the motor and the fixed end of the screw Clearance, etc., have a decisive influence on the accuracy of the reciprocating movement of the table along the guide rail. At present, many axial clearance adjustment devices on machine tools are integrated structures. Without proper adjustment devices, there will be axial movement of the shaft after assembly, which will not only reduce the service performance and life of the screw rod, but also reduce the machining accuracy. Expand the noise of the machine tool. Contents of the invention [0003] In order to overcome the above technical problems, the pr...
