[0002] During the production of automotive parts, assembly work needs to be carried out between parts. In order to speed up the assembly of automotive parts, the prior art uses an automatic screw locking device to perform the assembly work on automotive parts. However, when the automatic screw locking device in the prior art is actually used, it still has the following deficiencies;

[0003] First of all, after the automatic screw locking device in the prior art clamps the screw with a chuck, it uses an automatically rotating electric screwdriver to rotate the screw, so that it is tightened on the assembly threaded hole of the automotive part. However, dust and other impurity particles are likely to enter the chuck channel of the automatic screw locking device in the prior art during the feeding process. These impurity particles are likely to mix into the screw threads as the work progresses, resulting in damage to the screw during the subsequent process of screwing in the screw, thus having an adverse impact on the assembly work of the parts;

[0004] Secondly, when the automatic screw locking device in the prior art is in use, dust and other impurity particles are often adhered to the screw threads of the screws used.

Then, the intermediate shaft continues to feed downward, compressing the return spring. The square sleeve moves downward in the sleeve, causing the brush plate to leak out from the square groove, so that the brush surface contacts the clamping channels of the left chuck and the right chuck. Combining with the rotation effect of the intermediate shaft, the brush surface cleans the clamping channels, timely removing foreign dust and other impurity particles, preventing them from adhering to the thread of the screw-like part, and thus affecting the assembly work of the components. When the intermediate shaft moves upward, under the reset action of the return spring, the brush plate is stored back into the sleeve.

[0019] 2. The present invention is provided with a dust cleaning mechanism. When the bottom of the screw-like part is exposed, the fan starts to exhaust air outward, and the air flow is sucked in from the end pipe, so that the dust and other impurity particles attached to the bottom of the screw-like part are sucked into the air box and intercepted and filtered by the filter plate. Through the above method, the pre-dust cleaning function of the screw-like part is realized, preventing adverse effects on the subsequent assembly work. Brief Description of the Drawings

When the intermediate shaft 401 feeds downward, causing the tool head 406 to enter the clamping channels of the left chuck 309 and the right chuck 310 and contact the head of the screw-like part 314, the intermediate shaft 401 continues to feed downward, compressing the return spring 409. The square sleeve 411 moves downward in the housing 403, causing the brush plate 414 to leak outwards from the square groove 408, making the brush surface 415 contact the clamping channels of the left chuck 309 and the right chuck 310. Cooperating with the rotation effect of the intermediate shaft 401, the brush surface 415 cleans the clamping channels, thereby timely removing foreign dust and other impurity particles, preventing them from adhering to the threads of the screw-like part 314 and affecting the assembly work of the components. When the intermediate shaft 401 moves upward, under the reset action of the return spring 409, the brush plate 414 is stored in the housing 403.

[0042] Refer to Figure 10 As shown in the figure, the dust cleaning mechanism 5 includes side plates 501.

A end pipe 508 is fixedly installed at the end of the pipe body of the dust suction pipe 506, and the nozzle of the end pipe 508 is aligned with the bottom of the screw-like part 314;

[0043] In this embodiment, when the bottom of the screw-like part 314 is exposed, the blower 504 starts to exhaust air outwards. The air flow is sucked in from the end pipe 508, so that the dust and other impurity particles attached to the bottom of the screw-like part 314 are sucked into the air box 502 and intercepted and filtered by the filter plate 503. Through the above method, the pre-dust cleaning function of the screw-like part 314 is realized, thereby preventing adverse effects on the subsequent assembly work.

[0046] Working principle of the present invention: When the device is in use, in the initial state, the brush plate 414 is stored inside the sleeve 403. When the intermediate shaft 401 feeds downward, causing the tool bit 406 to enter the clamping channels of the left chuck 309 and the right chuck 310 and contact the head of the screw-like part 314, the intermediate shaft 401 continues to feed downward, compressing the return spring 409. The square sleeve 411 moves downward in the sleeve 403, causing the brush plate 414 to leak outwards from the square groove 408, so that the brush surface 415 contacts the clamping channels of the left chuck 309 and the right chuck 310. Combining with the rotation effect of the intermediate shaft 401, the brush surface 415 cleans the clamping channels, thereby timely removing foreign dust and other impurity particles, preventing them from adhering to the threads of the screw-like part 314, and thus affecting the assembly work of the components. When the intermediate shaft 401 moves upward, under the reset action of the return spring 409, the brush plate 414 is stored in the sleeve 403. When the bottom of the screw-like part 314 leaks out, the blower 504 starts to exhaust outwards, and the air flow is sucked in from the end pipe 508, so that the dust and other impurity particles attached to the bottom of the screw-like part 314 are sucked into the air box 502 and intercepted and filtered by the filter plate 503. Through the above method, the function of pre-cleaning the screw-like part 314 is realized, thereby preventing adverse effects on the subsequent assembly work.
