[0051] By adopting the above solution, by providing the linkage arm 804, when the movable block 802 moves in opposite directions, the linkage arm 804 can be deflected to push the lifting plate 701 and the locking tooth column 702 to move upward as a whole.

[0052] like Figure 8 As shown, one end of the first connection spring 803 away from the movable block 802 is fixedly connected to the inner wall of the fastening support platform 3 .

[0053] By adopting the above solution, the first connecting spring 803 is provided, and when the tension of the first connecting spring 803 is released, the two movable blocks 802 can be smoothly pushed to move toward each other as a whole and reset.

[0054] like Figure 3 As shown, the first pneumatic assembly 9 includes a first air cylinder 901, a first pneumatic rod 902, a push rod 903 and a second connecting spring 904;

[0055] The first air cylinder 901 is fixedly installed inside the fastening support platform 3 and in the middle of the inner side of the driving gear 6041, the first pneumatic rod 902 is movably installed in the inner cavity of the first air cylinder 901, the push rod 903 is fixedly installed at the bottom of the first pneumatic rod 902 and passes through the first air cylinder 901, and the second connecting spring 904 is fixedly installed between the bottom of the first pneumatic rod 902 and the inner wall of the first air cylinder 901.

[0056] By adopting the above solution, the second connecting spring 904 is provided. Due to the elastic force of the second connecting spring 904, it is convenient to assist in pushing the first pneumatic rod 902 to reset upward as a whole.

[0057] like Figure 3 and Figure 4 As shown, the inclined surfaces on both sides of the bottom end of the push rod 903 are matched with the inclined surface at the bottom of the movable block 802 , and the top threaded sleeve of the fastening support platform 3 is connected with the clamping screw 10 located above the first pneumatic rod 902 .

[0058] By adopting the above solution: by providing a push rod 903, when the operator rotates the tightening screw 10 downward as a whole, the first pneumatic rod 902 can drive the push rod 903 downward, so that the inclined surfaces on both sides of the bottom of the push rod 903 fit the inner inclined surface of the extrusion movable block 802, and smoothly drive the two movable blocks 802 to move in opposite directions.

[0059] like Figure 3 As shown, the second pneumatic assembly 11 includes a second air cylinder 1101, a second pneumatic rod 1102 and a ventilation pipe 1103;

[0060] The second air cylinder 1101 is fixedly installed inside the fastening support platform 3 and above and below the outside of the first air cylinder 901. The second pneumatic rod 1102 is movably installed in the inner cavity of the second air cylinder 1101, and the outer end is fixedly connected to the inner side of the outer end of the connecting frame 6042. The ventilation pipe 1103 is fixedly connected between the middle part of the inner side of the second air cylinder 1101 and the top of the outer side of the first air cylinder 901.

[0061] By adopting the above scheme: by providing a ventilation pipe 1103, when the first pneumatic rod 902 moves downward as a whole, the gap at the top of the inner cavity of the first gas cylinder 901 can be enlarged to generate negative pressure, so that the gas in the inner cavity of the second gas cylinder 1101 can be extracted through the ventilation pipe 1103, so as to drive the two second pneumatic rods 1102 to move towards each other.

[0062] The working principle and use process of the present invention:

[0063] First, the operator can open the door on the front of the processing machine 1, place the brake disc body 5 on the top of the fastening support platform 3, and rotate the clamping screw 10 downward to press the top of the brake disc body 5. At the same time, the first pneumatic rod 902 can be pushed downward to generate negative pressure in the inner cavity of the first air cylinder 901. The gas in the inner cavity of the second air cylinder 1101 can be introduced into the inner cavity of the first air cylinder 901 through the ventilation pipe 1103, so that the second pneumatic rod 1102 drives the two driving gears 6041 and the connecting frame 6042 to run in opposite directions as a whole, so as to drive the four driven gears 603, the mounting shaft 602 and the clamping arc block 601 to rotate outward as a whole. At the same time, the elastic force of the power spring 402 can increase the driving member 604 as a whole to drive the clamping arc block 601 to deflect outward to clamp the inner side of the corresponding inner diameter.

[0064] When the first pneumatic rod 902 moves downward, the pushing rod 903 can be pushed downward so that the outer inclined surface squeezes the inner inclined surface of the movable block 802, so as to push the two movable blocks 802 to move opposite to each other, and then the two linkage arms 804 will be deflected to push the lifting plate 701 and the locking tooth column 702 to move upward as a whole, until the locking tooth column 702 is completely inserted into the bottom inner groove of the installation shaft 602, which can ultimately improve the fixing effect of the installation shaft 602 and the clamping arc block 601 as a whole, so that the clamping arc block 601 can clamp the inner side of the brake disc body 5 more firmly.

[0065] After that, the grinding mechanism 2 can be started to grind the brake disc body 5. When the brake disc body 5 needs to be removed, the clamping screw 10 can be rotated upward until the bottom of the clamping screw 10 releases the downward pressure on the top of the first pneumatic rod 902, and then the elastic force of the second connecting spring 904 will be smoothly released to push the first pneumatic rod 902 upward, and at this time the pushing rod 903 will release the squeezing of the movable block 802 and move it back to back. At this time, the pulling force of the first connecting spring 803 will be released and drive the two movable blocks 802 to face each other, so that the linkage arm 804 pulls the lifting plate 701 and the locking tooth column 702 to move downward as a whole. The first pneumatic rod 902 is then moved upward to push the gas in the inner cavity at the top of the first air cylinder 901 through the ventilation pipe 1103 and introduced into the inner cavity inside the second air cylinder 1101, so that the air pressure in the inner cavity of the second air cylinder 1101 increases, thereby driving the two second pneumatic rods 1102 to push the two driving members 604 to move in opposite directions, and finally the driven gear 603, the mounting shaft 602 and the clamping arc block 601 are driven to rotate inward as a whole, so that the clamping arc block 601 releases the clamping of the inner side of the brake disc body 5, and then the brake disc body 5 can be taken.
