[0002] CNC machine tools are programmed and controlled by numerical control machining languages. The positioning devices currently available on the market cannot automatically position the placed parts during use, and manual positioning may result in inaccurate positioning.

[0003] Among them, a positioning fixture for CNC machining disclosed in application number CN202121841542.3 is also an increasingly mature technology. Through the set electromagnet, it can cooperate with the set suction cup and the set piston rod to squeeze under the action of hydraulic pressure, so as to further improve the stability of the workpiece fixation and clamping, thereby facilitating the stable progress of subsequent processing; through the set outer frame ribs, the surface area of ​​the piston mainboard can be effectively increased, thereby reducing the pressure on the surface of the piston mainboard under hydraulic pressure, which is beneficial to improve the service life of the device.

[0004] A CNC machining center fixture quick positioning device disclosed in CN202021801264.4 is also an increasingly mature technology. It includes a base assembly, a fixture assembly and a fixture fixing seat. The fixture assembly is arranged on the top of the base assembly and on the outside of the base assembly. The outside of the base assembly is provided with a fixture assembly, which is arranged on the top of the base assembly. The positioning device cooperates with the adjusting block and the fixture assembly, and can adjust the distance between the two adjusting blocks according to the size of the workpiece, thereby solving the problem that the distance between the clamping plates is not convenient for adjusting the pressure plates in the past. Through the cooperation between the fixture fixing seat and the air pipe body, the debris generated after processing is blown away to avoid the debris affecting the processing effect of the CNC machine tool, thereby solving the problem that it is inconvenient to clean the debris generated by processing in the past. Through the cooperation between the fixture block and the clamp body, the effect of being able to be fixed and easy to disassemble by replacing it with a bolt and screwing it according to the processing requirements is achieved, thereby solving the problem of cumbersome operation of the previous fixture fixing method.
