A special CNC machine tool for small parts processing

Abstract

The invention discloses a special numerical control machine tool for machining a small part. The special numerical control machine tool comprises a machine tool body, a control mechanism and a three-axis machining mechanism; the Y-axis machining mechanism comprises a liftable large slide carriage; an X-axis machining mechanism comprises an X-axis ball screw; an X-axis stepping motor is used for driving the X-axis ball screw so that a small slide carriage can be driven to move horizontally by an X-axis nut; two groups of worktables and a row tool type tool magazine are detachably installed on the small slide carriage; two Z-axis machining mechanisms are arranged; each Z-axis machining mechanism comprises a Z-axis ball screw; and each Z-axis stepping motor is used for driving the corresponding Z-axis ball screw so that an electric spindle can be driven to move horizontally by a Z-axis nut. The special numerical control machine tool disclosed by the invention improves the part machining efficiency, increases the percent of pass of products, guarantees the machining quality and the stability of the machining quality, can be provided with different cutting tools according to the machining content of different types of work pieces so as to implement various machining of milling, drilling, chamfering, deburring and the like, realizes procedure centralization and machining automation of the small part, and alleviates the labor intensity of a worker.

Description

technical field [0001] The invention relates to the field of numerically controlled machine tools, in particular to a special numerically controlled machine tool which includes a tool changer system and is applied to many and relatively complicated machining processes, and particularly relates to a special numerically controlled machine tool for processing small parts. Background technique [0002] At present, the processing of small parts is mainly done manually, that is, through manual operation, different contents are processed on multiple single-function machine tools, and the tooling used is only a simple fixture. In addition, CNC lathes, CNC milling machines, machining centers and other CNC equipment have been popularized on the market, but these are popular CNC equipment, or are only suitable for single-piece small batch production, or are expensive, and cannot be used for small parts. processing. [0003] In the vast majority of small and medium-sized enterprises, t...

AI Technical Summary

Problems solved by technology

Its efficiency is low, artificial long-term continuous single sitting posture, continuous fixed repetitive movements, high labor intensity, serious fatigue damage to some parts of the body, coupled with the technical differences of operators, it is difficult to overcome manual processing errors, and the inspection and detection pass rate is not easy to improve. Difficult to maintain consistent quality

However, the general CNC machine tools require large parts and cannot clamp small parts, and are more suitable for single-piece production, and the efficiency is very low.

Although a general machining center can use multiple knives to carry out comprehensive processing of multiple processes and content, which reflects the concentration of processes, it is also not suitable for the processing of small parts, and the equipment is also expensive.
