The shaft head includes a shaft head seat, a fixed splint, a movable splint, nuts, and pins. The nut is connected to the shaft head seat through threads, and the abrasive tool is clamped between the fixed splint and the movable splint. The nut locks the fixed splint, the movable splint, and the abrasive tool. , There are two pins of different sizes on one side of the shaft head seat, pin one and pin two, pin one matches the size and shape of the pin groove at the left end surface of the motor shaft, pin one is placed in the pin groove and locked . The pin two is connected with the pull rod union buckle. The shaft head, the cutting fixture, and the pull rod union buckle rotate with the motor shaft.

One end of the center pull rod is connected to the finale head, and a movable finale handle is used as a supporting tool, and the other end is connected to a pull rod with a joint buckle. There is also a spring return structure on one side of the center tie rod. The movable finale handle is a lever structure. The movable finale handle and the spring return mechanism cooperate to complete the horizontal left and right movement of the central tie rod, so that the center pull rod pushes the shaft head to move horizontally left and right to realize the pin and pin. The separation and closing of the groove completes the disassembly and replacement of the shaft head.

Compared with the prior art, the beneficial effects of the utility model are:

By adopting the above-mentioned technical scheme, since the polishing function is added to the existing single cutting function, the equipment can achieve the integration of cutting and polishing;

The independently detachable shaft head can be used to clamp different abrasive tools, making it more applicable.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model will be further described. It should be noted here that the descriptions of these embodiments are used to help understand the utility model, but are not intended to limit the utility model. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a cutting and polishing integrated special motor includes a motor body 1, a cutting fixture 2, a shaft head 3, and a movable finale handle 4.

The shaft head 3 is a grinding fixture with a double lock pin structure, and the nut 33 is configured to clamp and fix the grinding tool 32 (grinding wheel), and the shaft head 3 is connected with the motor shaft 5; the cutting fixture 2 includes a fixed chuck 21 and a movable chuck 22, The fixed cutting tool is clamped between the fixed chuck 21 and the movable chuck 22, and the cutting fixture 2 is connected to the motor shaft 5; the motor shaft 5 is a hollow shaft, and the hollow structure runs through to the end faces on both sides, and there are two pin grooves on the left side , The hollow structure inside the motor shaft 5 is provided with a central pull rod 6 .

As shown in Fig. 2, described shaft head 3 comprises shaft head seat 31, movable splint 36, fixed splint 37, nut 33, pin one 34, pin two 35, and nut 33 is connected by threaded shaft head seat 31, movable splint 36 and The grinding tool is clamped between the fixed splints 37 and locked and fixed by nuts 33.
