[0019] The technical solution of the utility model is further described below in conjunction with specific implementation methods:

[0020] like Figure 2 As shown, a fixture for machining the positioning surface of a V-shaped blade 1 on a surface grinder comprises a base 2 and a clamping plate 3. A positioning mechanism is provided on the front of the base 2 to place the blade 1 in a fixed position. The blade 1 is fixed to the base 2 through the clamping plate 3. The clamping plate 3 is used to prevent the blade 1 from falling out when the fixture is turned over. There are three reference surfaces for grinding the blade 1 on the back of the base 2. The back cross-section shape is a trapezoid, as shown in FIG. Figure 1 and Figure 3 As shown, the shape and size of the reference surface are the same as the shape and size into which the insert 1 is to be machined.

[0021] like Figure 2 As shown, a mounting opening is provided on the base 2, and the positioning mechanism includes an end face positioning member 4, a side face positioning member 5 and a bottom face positioning member 5, and the end face positioning member 4, the side face positioning member 5 and the bottom face positioning member 5 are respectively located at the end, side and bottom of the mounting opening to accurately position the installation of the blade 1.

[0022] Before grinding the blade 1, the blade 1 is inserted into the mounting port perpendicular to the front side of the base 2 and installed in a fixed position through a positioning mechanism. The fixture is then turned over and processed on a flat grinder to grind the excess edges and corners of the blade 1 along the reference surface of the fixture, thereby making two V-shaped positioning surfaces of the blade 1.

[0023] A magnetic attraction piece is provided in the installation opening to attract the blade 1 , so that the blade 1 is fixed more firmly.

[0024] There can be several installation openings so that multiple blades 1 can be processed simultaneously, thereby improving production efficiency.

[0025] The angle accuracy of the reference surface is consistent with the target angle accuracy of the blade 1 grinding, so that the processed blade 1 completely replicates the accuracy of the fixture, and there is no need to worry about the accuracy of the blade 1.

[0026] This embodiment is only a further explanation of the present invention, not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
