[0023] The detection mechanism 11 includes an electric telescopic rod 111, a connecting block 112, a displacement sensor 113 and a contact switch 114. The electric telescopic rod 111 is fixed to the lower end of the flat top 9, the connecting block 112 is fixed to the extended end of the electric telescopic rod 111, and the displacement sensor 113 and the contact switch 114 are both fixed to the lower end of the connecting block 112, and the lower parts of the displacement sensor 113 and the contact switch 114 are level.

[0024] The adjusting mechanism 3 includes a fixing seat 31 , a screw rod 32 , an adjusting hand wheel 33 and a first spring 34 .

[0025] The fixing seat 31 is fixed on the detection platform 1 and is located on one side of the fixing mechanism 7. The screw 32 is threadedly connected to the fixing seat 31. Two first springs 34 are provided and connected between the fixing seat 31 and the fixing mechanism 7. The adjusting hand wheel 33 is located at the end of the screw 32.

[0026] The fixing mechanism 7 comprises a fixing platform 73 , a limiting groove 71 is provided in the middle of the fixing platform 73 , and an electromagnet 72 is provided at the bottom of the limiting groove 71 .

[0027] A second spring 15 is installed between the telescopic rod 12 and the support column 8 .

[0028] The grinding mechanism 4 includes an electric cylinder 41 , a first motor 42 and a grinding block 43 ; the first motor 42 is fixed to the extended end of the electric cylinder 41 , and the grinding block 43 is fixed to the output end of the first motor 42 .

[0030] Working principle: Place the auto parts on the electromagnet 72, start the electromagnet 72, use the strong suction of the electromagnet 72 to firmly fix the auto parts, start the electric cylinder 41 to extend its length, so that the lower end of the grinding block 43 contacts the auto parts, start the second motor 18, and the output end of the second motor 18 drives the gear 14 to rotate. When the gear 14 and the rack 13 are meshed with each other, the gear 14 drives the telescopic rod 12 to move linearly, thereby driving the grinding mechanism 4 to move linearly. At this time, one second spring 15 is in an extended state, and the other second spring 15 is in a compressed state. When the gear 14 goes out of the range of the rack 13, due to the elastic force of the two second springs 15, the grinding mechanism 4 is reset, thereby realizing the reciprocating linear motion of the grinding mechanism 4.

[0031] The output end of the first motor 42 rotates to drive the grinding block 43 to rotate, thereby efficiently grinding the auto parts. After the grinding is completed, the adjusting hand wheel 33 is rotated, and the adjusting hand wheel 33 rotates to drive the screw 32 to rotate. Since the screw 32 and the fixing seat 31 are threadedly matched, the screw 32 will squeeze the fixing table 73, so that the fixing table 73 moves in a straight line, thereby moving it to the lower side of the detection mechanism 11, and the detection mechanism 11 detects whether the auto parts are qualified.
