DETAILED DESCRIPTION

[0019] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1 , Figure 2 The fan-shaped pad chamfer positioning tool shown in the figure includes a positioning base plate 1, and the positioning base plate 1 is provided with two groups of front and rear cylindrical bosses 2, the positioning and size of the cylindrical bosses 2 match the positioning holes on the fan-shaped pad 3, and the middle part of the positioning base plate 1 is provided with a clamping component 4 for positioning the fan-shaped pad 3, and the two sides of the positioning base plate 1 are provided with clamping components 2 for positioning the positioning base plate 1 on the workbench, and the positioning base plate 1 is also provided with alignment holes 5.

[0021] In this embodiment, each group of the cylindrical bosses 2 is provided with two, and the two cylindrical bosses 2 are symmetrically arranged and integrally formed with the positioning base plate 1 .

[0022] In this embodiment, a detachable cylindrical boss 6 is further provided between the two symmetrically arranged cylindrical bosses 2 , and the detachable cylindrical boss 6 is threadedly connected to the positioning base plate 1 .

[0023] In this embodiment, the clamping assembly 4 includes a positioning column 401 vertically fixed on the positioning base plate 1, and a pressure plate 402 is mounted on the positioning column 401. The pressure plate 402 is clamped on the fan-shaped pad 3 by a nut 403 screwed on the positioning column 401.

[0024] In this embodiment, the positioning column 401 is threadedly connected to the positioning base plate 1, and the positioning base plate 1 is provided with a plurality of threaded holes 7 for installing the positioning column 401. The purpose of providing a plurality of threaded holes 7 is to adjust the position of the positioning column 401 according to the length of the fan-shaped pad 3 to ensure that the fan-shaped pad 3 is pressed tightly.
