[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: an upper pressing type high-precision integral blade disk indexing device, comprising a base 1, such as Figure 1 As shown, the base 1 is a rectangular plate structure, and the surface of the base 1 is fixedly connected to the cantilever 2. Figure 2 As shown, the cantilever 2 is in an "L" shape, and the cantilever 2 is movably provided with a blade disk locking screw 3, which is vertically arranged and located above the base 1. Figure 3 As shown, a shaft sleeve 4 cooperating with the blade disk is rotatably provided on the base 1, and a positioning pin 5 is provided on the base 1. The blade disk is mounted on the shaft sleeve 4 and can be rotated on the base 1. The positioning pin 5 extends into the gap between adjacent blades to achieve the indexing positioning of the blade disk, and the blade disk can be fixed by tightening the blade disk locking screw 3;

[0019] Specifically, a sleeve locking screw 6 for locking the sleeve 4 is provided at the side wall of the base 1. The sleeve 4 can be fixed by tightening the sleeve locking screw 6, and the blade disk can be further locked.

[0020] Specifically, if Figure 3 As shown, a circular through groove 7 is provided through the end surface of the base 1, and the shaft sleeve 4 is arranged inside the circular through groove 7. The shaft sleeve 4 can be customized according to different leaf disk sizes and can be replaced to increase the applicability of the equipment;

[0021] Specifically, the sleeve locking screw 6 passes through the side wall of the circular through groove 7 and contacts the sleeve 4, so that when the sleeve locking screw 6 is tightened, the sleeve locking screw 6 abuts against the side wall of the sleeve 4 to achieve the positioning effect on the sleeve 4;

[0022] Specifically, the positioning pin 5 is movably arranged with the base 1, and the positioning pin 5 can slide up and down. The side wall of the base 1 is screwed with a pin locking screw 8 for fixing the positioning pin 5. After the positioning pin 5 is lifted to position the blade, the positioning pin 5 is positioned by tightening the pin locking screw 8;

[0023] Specifically, a positioning shaft 9 is screwed on the upper surface of the base 1. When the last blade needs to be cut, the positioning shaft 9 is rotated to raise the positioning shaft 9, and the blade is located between the positioning shaft 9 and the positioning pin 5. When only one blade is left, the blade disk can still be positioned.

[0024] When the utility model is used, the bottom of the blade disk is installed on the shaft sleeve 4, and the blade disk can rotate on the base 1. The blade is positioned by tightening the blade disk locking screw 3, and the positioning pin 5 is lifted.
