An anti-collision knife CNC machine tool

Abstract

The invention discloses an anti-collision knife numerical control machine tool, comprising a machine tool body, an x-axis motor, an x-axis screw, a y-axis screw, a y-axis motor, a z-axis slide rail, a z-axis screw, a fixing frame and a fourth motor , shell, fixture, collection trolley and anti-collision tool device, the built-in milling cutter in the fixture accidentally hits the support plate downwards during the debugging process, and under the action of the spring force, the support plate slides down to provide buffering for the built-in milling cutter in the fixture , to prevent the built-in milling cutter of the fixture from directly hitting the built-in milling cutter of the fixture and cause the cutter to break and damage. After the debugging of the CNC program is completed, the fifth motor starts to rotate forward, so that the fourth screw rod moves upward, and the connection block at the top is attached to the limit. The bottom end face of the block is used to fix the top support plate. During the deep hole machining of the workpiece, the workpiece will sink under the action of the spring force, which will cause the spring to buffer the workpiece and cause workpiece accuracy errors. This device fixes the support plate to avoid The machining error of the workpiece is affected by the spring force during the machining process.

Description

technical field [0001] The invention relates to the related field of machine tools, in particular to an anti-collision knife numerical control machine tool. Background technique [0002] A CNC machine tool is an automatic machine tool equipped with a program control system. The control system can logically process the program specified by the control code or other symbolic instructions, decode it, represent it with coded numbers, and enter the CNC through the information carrier. After the operation processing, the numerical control device sends out various control signals to control the action of the machine tool. Since the milling cutter of the machine tool needs to be moved outside the workpiece during the debugging of the numerical control programming process, the inexperienced programmers are prone to programming errors. As a result, the milling cutter directly hits the worktable during the machining process, resulting in damage to the milling cutter. Therefore, an anti...

AI Technical Summary

Problems solved by technology

[0004] 1. Existing anti-collision knife CNC machine tools, machine tool milling cutters in the process of debugging CNC programming, need milling cutters to move on the outside of the workpiece, programming errors will easily cause milling cutters to directly hit the workbench and cause damage to the milling cutters, and generally have The machining accuracy of the spring buffer device is low

[0005] 2. Existing anti-collision knife CNC machine tools, CNC machine tools often roll up metal scraps when cutting metal parts, ordinary machine tools do not have a compacting device for metal scraps in the collection box, resulting in frequent replacement of the collection box and making it very convenient to use
