A kind of aluminum alloy CNC machining tool head replacement structure

Abstract

The invention discloses an aluminum alloy numerically controlled machining tool head replacement structure, which comprises a rotary head, a cutter, a first connecting spring, a steel wire and a second connecting spring. The blocks are connected with each other, and the connecting block is connected with the tool through the installation groove. The outer surface of the connecting block is provided with a limit hole, and the limit hole and the limit shaft are connected with each other, and the limit shaft passes through the limit hole and the positioning The round plate is fixedly connected. The replacement structure of the aluminum alloy CNC machining cutter head, the staff can separate the sleeve from the support shaft first by toggling the sleeve, and release the positioning of the support shaft, and then the sleeve pulls the steel wire through the limit plate , so that the steel wire drives the support shaft, the positioning circular plate and the limit shaft to slide and run, so that the limit shaft and the limit hole are separated from each other to release the positioning, which increases the convenience for the staff to replace the tool.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to an aluminum alloy numerical control machining cutter head replacement structure. Background technique [0002] Numerical control is mainly a system that performs some or all of the basic digital control functions through a dedicated computer that can store programs. Carrying out CNC machining requires the use of aluminum alloy CNC machining cutter head and the replacement structure of the cutter head, but the existing aluminum alloy CNC machining cutter head replacement structure still has the following problems; [0003] 1. Generally, the bolts are used to fasten the work directly, but after the bolts are fixed, the subsequent operation of the cutter head will cause vibration when processing the material, which will easily affect the bolts and cause the bolts to occur. The phenomenon of loose rotation reduces the overall stability; [0004] 2. Assembling by...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a replacement structure for aluminum alloy CNC machining cutter head, to solve the current market aluminum alloy numerical control machining cutter head replacement structure proposed by the above-mentioned background technology, which is assembled by bolts, and the cutter head is fixed and subsequently replaced The operation is not convenient enough, it needs to be rotated and fixed or rotated and loosened by external tools, which increases the cumbersome phenomenon of the overall operation, and long-term operation and use will easily cause the bolts to wear and affect the overall assembly work.
