Anti-cutter-collision numerical control machine tool

Abstract

The invention discloses an anti-cutter-collision numerical control machine tool. The machine tool comprises a machine tool body, an x-axis motor, an x-axis lead screw, a y-axis lead screw, a y-axis motor, a z-axis sliding rail, a z-axis lead screw, a fixing frame, a fourth motor, a shell, a clamp, a collecting cart and an anti-cutter-collision device. In the debugging feeding process of a clamp built-in milling cutter, the milling cutter accidentally collides with a supporting plate, under the effect of spring force, the supporting plate slides downwards to provide buffer for the clamp built-in milling cutter, the phenomenon that the clamp built-in milling cutter is in direct collision, and the clamp built-in milling cutter is broken and damaged is avoided, after numerical control programdebugging is completed, a fifth motor is started to rotate forwards to enable a fourth lead screw to move upwards, and a connecting block at the top end is attached to the bottom end face of a limiting block to fix a top end supporting plate, in the deep hole machining process of a workpiece, due to the fact that the workpiece sinks under the action of the spring force, buffering of the spring forthe workpiece causes workpiece precision errors, the supporting plate is fixed through the device, and the workpiece machining errors are prevented from being affected by the action of the spring force in the machining process.

Description

technical field [0001] The invention relates to the related fields 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, which can logically process the program specified by the control code or other symbolic instructions, decode it, express it in coded numbers, and input it into the CNC machine tool through the information carrier. The device is processed by the numerical control device to send various control signals to control the movement of the machine tool. Since the milling cutter of the machine tool needs to move the cutter on the outside of the workpiece during the debugging of the CNC programming process, inexperienced programmers are prone to programming errors. As a result, the milling cutter directly hits the workbench during the processing and causes damage to the milling cutter. Therefore, an anti-collision ...

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
