Permanent magnet motor driven vertical lathe

Abstract

The invention provides a permanent magnet motor driven vertical lathe. A lathe bed is mounted on the upper portion of a base. A workbench is mounted in the position, located on the front portion of the lathe bed, of the upper portion of the base. The workbench is connected with a permanent magnet motor located in the base. An encoder is mounted on the workbench. The encoder and the workbench are coaxially mounted. The front side of the lathe bed is provided with guide rails. A cross beam is slidably mounted on the front side of the lathe bed through the guide rails. A lifting lead screw is connected to the rear side of the cross beam. The lifting lead screw is connected with a vertical servo motor. A cross beam sliding seat is slidably mounted on the front side of the cross beam. The crossbeam sliding seat is connected with a horizontal servo motor through a horizontal lead screw. A vertical tool post is mounted on the front portion of the cross beam sliding seat. A ram is mounted onthe lower portion of the vertical tool post through a rotary sliding seat. According to the permanent magnet motor driven vertical lathe, the workbench is provided with the eight-speed permanent magnet motor and can realize stepless speed regulation; the permanent magnet motor driven vertical lathe is compact in structure and low in energy consumption, realizes turning of high-precision threads through the encoder arranged on the workbench; the cross beam is driven to do horizontal and vertical motion through the permanent magnet motor; the stability of the permanent magnet motor driven vertical lathe is improved, and power consumption of the permanent magnet motor driven vertical lathe is reduced; and the permanent magnet motor driven vertical lathe is convenient and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools. Background technique [0002] Vertical lathes are large-scale mechanical equipment used to process large and heavy workpieces with large radial dimensions and relatively small axial dimensions and complex shapes. Such as the cylindrical surface, end surface, conical surface, cylindrical hole, conical hole, etc. of various discs, wheels and sleeves. It can also be used for threading, spherical turning, profiling, milling and grinding with the help of additional devices. Generally, it can be divided into single-column and double-column. [0003] Traditional vertical lathes usually have complex structures, large volumes, and high energy consumption. Moreover, the operation is complicated and the processing accuracy is low, which cannot meet the requirements of precision parts processing. Contents of the invention [0004] In order to solve the above-mentioned problems ex...
