The numerical control machine tool and the common machine tool are commonly provided with cutters for cutting, grinding, polishing and the like, so the cutters are indispensable tools in the machining process. Before the cutter is used, a grinding device is generally used for grinding the cutter blade; at present, the cutter is polished mainly for the manpower is polished and the machinery is polished two kinds, and the processing intensity of cutter is polished to the manpower is big, and work efficiency is low, and mechanical equipment of polishing's processing intensity is big, and the efficiency of polishing is high.

In the production process of manufacturing industries such as stirring, cutting and the like, cutters are indispensable; the cutter part is subjected to burrs and even pits or blunt edges of the cutter if the cutter is used for a long time, but unnecessary production cost is wasted if the cutter is directly discarded, so that the cutter is generally subjected to grinding processing, and the cutter edge is resharpened and can be reused.

When the existing cutter is subjected to grinding processing, the problems exist that stable fixed mounting cannot be carried out on a cutter bar with a rectangular section or a cutter bar with a circular section during cutter grinding, the application and replacement of a fixed structure are not flexible enough, the fixed mounting cannot be carried out on cutters of the cutter bars with different section shapes, the mounting and fixing of the cutters during grinding are difficult to ensure, and the grinding quality of the cutters is influenced; moreover, when the cutter is grinded by the rotation angle, the rotating structure part of the rotated cutter is not pressed and fixed, so that the anti-slip and anti-loose fixing cannot be realized, and the cutter can swing left and right and is unstable. Therefore, we need a tool grinding fixing device, which solves the problems that the tools of the tool bars with different cross-section shapes cannot be fixedly installed during tool grinding, and the rotating structure part cannot be pressed and fixed, so that the anti-slip and anti-loose fixing cannot be realized.

For example, the utility model provides a fixing device during cutter grinding is provided in current patent publication No. CN212735286U, the device is through being provided with adjusting frame, the threaded rod, the screw thread piece, first fixed frame, the fixed frame of second, the fixture block, the draw-in groove, the slipmat, the dead lever, the stopper, rotate handle and foam-rubber cushion, make the threaded rod drive two screw thread pieces through the rotation and carry out relative motion, at the in-process of moving, the first fixed frame of reuse and the fixed frame of second accomplish and fix the cutter, whole fixing device, the structure sets up rationally, the simple operation, can be effectual and quick realization grinding blade's installation location and fixed, the suitability is strong and the practicality is good, improve the grinding efficiency to the cutter.

But its device is applicable to the installation location and the fixed of realization grinding blade that can be effective and quick, and suitability is strong and the practicality is good, improves the grinding efficiency to the cutter, can not carry out fixed mounting to the cutter of the cutter bar of different cross-section shapes.

The existing tool grinding fixing device cannot be used for fixedly mounting tools of tool bars with different cross-sectional shapes, the application and replacement of a fixing structure are not flexible enough, the mounting and fixing of the tools during grinding are difficult to ensure, and the grinding quality of the tools is affected; moreover, the rotary structure part of the cutter after rotation is not pressed and fixed, so that the phenomenon that the cutter swings left and right and is unstable can not be realized.
