Novel vertical numerical control turning and grinding composite machine tool

Abstract

The invention discloses a novel vertical numerical control turning and grinding composite machine tool. The novel vertical numerical control turning and grinding composite machine tool comprises a base and an alternating current servo motor, wherein the top end of the base is provided with a workbench, the upper surface of the base is provided with a stand column, the alternating current servo motor is arranged on the outer side of a protective shell, the tail end of a rotating shaft is connected with a coupler, the tail end of the coupler is connected with a transmission lead screw, and the front side of a cross beam is sequentially provided with a grinding tool rest and a turning tool rest from left to right. The novel vertical numerical control turning and grinding composite machine tool is convenient to install, can conveniently adjust the pretightening of an X-axis screw rod and a Z-axis screw rod, can increase the rigidity of the screw rods, saves the occupied area, improves theautomation degree, improves the depth of a ground inner hole, increases the range of the ground inner hole, reduces the vibration of a grinding wheel in the grinding process, accordingly improves thegrinding precision, has the characteristics of high positioning precision, stability, reliability, compact structure and the like and can ensure normal work of a spindle under the conditions of largecutting depth and large feeding.

Description

technical field [0001] The invention relates to the technical field of numerically controlled lathes, in particular to a novel vertical numerically controlled turning-grinding compound machine tool. Background technique [0002] CNC machine tools are mostly used for finishing grinding of cylinders, cones, ball bearing inner and outer rings, raceways and end faces in multiple batches, varieties and specifications. It is also suitable for gears, sleeves and other parts. High-precision grinding processing, with the sealing surface of hard-sealed valves in the valve industry and the precision requirements for large-scale bearing mounting surfaces in textile machinery, the requirements for CNC machine tools are getting higher and higher. [0003] But existing numerical control lathe has the following problems: [0004] 1. It is inconvenient to install and adjust the pre-tightening of the X-axis screw rod and the Z-axis screw rod, and it is impossible to increase the rigidity of ...

AI Technical Summary

Problems solved by technology

[0010] The purpose of the present invention is to provide a new type of vertical CNC turning and grinding compound machine tool, to solve the problem that the existing vertical CNC turning and grinding compound machine tool proposed in the above background technology is not easy to install and adjust the pre-installation of the X-axis screw rod and the Z-axis screw rod. Tight, can not increase the rigidity of the screw, the degree of automation is low, occupy a large working surface, can not improve the depth of the grinding inner hole, can not ensure that the spindle can work normally under the conditions of large depth of cut and large feed question
