Double-disk-type-knife-rest single main shaft numerically-controlled lathe

Abstract

The invention discloses a double-disk-type-knife-rest single main shaft numerically-controlled lathe. The double-disk-type-knife-rest single main shaft numerically-controlled lathe comprises a base, a main shaft box, a main shaft motor, a motor bottom plate, a belt wheel, a lathe body, an angling cylinder, a main shaft assembly, a main shaft, an upper knife rest, an upper lathe saddle, an upper belt wheel box, an upper lathe saddle sliding board, an upper Z-direction lead screw, a first upper guide rail, a second upper guide rail, an upper servo motor, an upper Z-direction belt wheel box, a lower servo motor, a lower Z-direction belt wheel box, a first lower guide rail, a second lower guide rail, a lower Z-direction lead screw, a lower lathe saddle, a lower knife rest, a lower lathe saddle sliding board and a lower belt wheel box, wherein the upper lathe saddle and the lower lathe saddle are vertically arranged in a paralleled mode. According to the double-disk-type-knife-rest single main shaft numerically-controlled lathe, the upper knife rest and the lower knife rest are arranged reasonably and not interfered mutually, compared with a non-parallel-double-knife-rest lathe, the stroke of each knife rest is larger; a plurality of tools can be placed in the upper knife rest and the lower knife rest respectively, several faces of parts can be machined at the same time, machining speed is high, and production efficiency is high; and the use of multiple knife rests enables machining of the several faces of the parts to be finished under the condition of one-time clamping, and therefore machining accuracy and uniformity are improved.

Description

technical field [0001] The invention relates to a single-spindle numerical control lathe with double-disk tool holders, especially for fast and precise machining of end cap parts. Background technique [0002] CNC machine tools are important products of the machine tool industry. Based on the technology platform for the development of high-speed, compound, intelligent and efficient CNC machine tools, it has become a key technology for the development of the CNC machine tool industry. These technologies include: high-speed cutting, multi-functional composite processing, digital manufacturing, etc. At present, double-turret CNC lathes are widely used in production and processing because they can use multiple tools for simultaneous cutting, shorten working hours, and improve production efficiency. One turret is installed, which often causes geometric interference and process interference in actual machining, which brings great challenges to the scope of application and safety ...

AI Technical Summary

Problems solved by technology

At present, double-turret CNC lathes are widely used in production and processing because they can use multiple tools for simultaneous cutting, shorten working hours, and improve production efficiency. A tool holder is installed, which often causes geometric interference and process interference in actual processing, which brings great challenges to the scope of application and safety of double-turret lathes

Moreover, most of the double-tool post lathes on the market currently have a main tool post and a pair of tool posts, one for rough machining and one for finish machining, which also brings many restrictions to production and processing.
