Multi-stable machining insert fixing device for numerical control machine tool

Abstract

The invention discloses a multi-stable machining insert fixing device for a numerical control machine tool, which structurally comprises an insert assembly machine body, an insulating protective ring,an electromagnet, a rubber pad and a negative pressure suction hole, wherein the insulating protective ring is embedded and glued in the middle of the top end of the insert assembly machine body, theelectromagnet is a circular ring and is embedded and glued in the insulation protection ring and is electrically connected with the insert assembly machine body. The multi-stable machining insert fixing device for a numerical control machine tool is characterized in that, 1, the device can be driven to generate negative pressure by rotating the knob to suck the workpiece, so that the device can be prevented from being influenced by the side surface of the workpiece, and the embedded workpiece can be placed in the negative pressure hole to ensure the stability of the workpiece and prevent thedeflection processing failure, and be easily to use; 2, the device can also drive the electromagnet to operate when the negative pressure is generated, so that the electromagnet can suck the placed workpiece to achieve the multiple workpieces stability and prevent the danger and inconvenience caused by the workpiece instability under the condition of single re-suction, and be easily to use.

Description

technical field [0001] The invention relates to a multiple and stable machining insert fixing device for a numerically controlled machine tool, which belongs to the field of insert fixing devices. Background technique [0002] When CNC lathes are used for processing, in order to facilitate the positioning and stabilization of the workpiece, it is often necessary to fix the workpiece, and for different workpieces, different workpiece fixing devices are required for fixing. The insert fixing device is an inlay workpiece. A positioning and stabilizing device used during processing. [0003] When the traditional insert fixing device is used, 1. It often adopts the clamping fixing method, but the clamping fixing method has higher requirements on the surface of the workpiece, and it is easy to cause unstable clamping or poor positioning due to the surface of the workpiece. It is easy to cause inconvenience such as processing failure; 2, the fixing method of the existing device is...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a multiple and stable machining insert fixing device for CNC machine tools, so as to solve the problem that when the traditional insert fixing device is in use, 1. The fixing method of clamping is often used, but The fixing method of clamping has high requirements on the surface of the workpiece, which may easily lead to unstable clamping or poor positioning due to the surface of the workpiece, which may easily cause inconvenience such as processing failure; When the single stabilization method is loose, it will directly affect the danger and inconvenience of the equipment, such as instability and falling of the equipment.
