Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1-5 , an embodiment provided by the present utility model: A deburring and precision finishing device for the outer ring of a bearing hub includes a processing component 2 and a protection component 1, and the protection component 1 is installed at the front of the processing component 2;

[0024] The protective component 1 includes a front baffle 102, on which a handle 101 is fixedly connected. An upper cover plate 103 is fixedly connected to the upper part of the front baffle 102, and mounting holes are provided on the upper cover plate 103, which are adapted to the mounting posts 205;

[0025] Before processing, the upper cover plate 103 is installed on the mounting post 205, and the whole protective component 1 is installed at the front part of the processing component 2, providing a good protective effect for the deburring processing operation, avoiding chip splashing and hurting people, and improving the safety of processing.

[0026] The processing component 2 includes a processing seat 201, a support frame 207 is fixedly connected to the rear part of the processing seat 201, an electric push rod 206 and a mounting post 205 are fixedly connected to the support frame 207. The output end of the electric push rod 206 passes through the support frame 207, and a cutting part 3 is arranged at the end;

[0027] The cutting part 3 includes a driving motor 304 fixedly installed at the output end of the electric push rod 206. The output end of the driving motor 304 is fixedly connected with a limiting cylinder body 303. The lower part of the limiting cylinder body 303 has an opening, which is mutually adapted to the adapting column 402. A mounting cutter disc 302 is fixedly connected to the lower part of the limiting cylinder body 303. Cutting knives 301 adapted to the outer ring of the automotive wheel hub bearing are fixedly connected to the mounting cutter disc 302. The number of the cutting knives 301 is three, and they are evenly arranged in a circle. Chutes 204 and limiting channels 203 are arranged on the processing seat 201. The number of the chutes 204 is two, and they are axially symmetrically arranged. The length of the limiting channel 203 is the same as the distance between the two positioning parts 4. A moving seat 202 is slidably connected to the chute 204. A transverse moving push rod 208 is fixedly installed at the lower part of the processing seat 201. The output end of the transverse moving push rod 208 is fixedly connected with a connecting block 209. The connecting block 209 passes through the limiting channel 203 and is fixedly connected with the moving seat 202;

[0028] Two positioning parts 4 are installed on the moving seat 202. The positioning part 4 includes a positioning disc 401 fixedly installed on the moving seat 202. An adapting column 402 is fixedly connected to the center of the positioning disc 401. A plurality of positioning columns 403 are fixedly connected to the positioning disc 401. The positioning columns 403 are adapted to the through holes of the outer ring of the automotive wheel hub bearing, and the plurality of positioning columns 403 are evenly arranged in a circle.

[0029] During processing, place the outer ring of the automotive wheel hub bearing to be processed on the outer positioning member 4. Since there are mounting holes on the outer ring of the automotive wheel hub bearing, it can be adapted to the positioning column 403, thereby fixing the outer ring of the automotive wheel hub bearing and preventing it from rotating. Then, the transverse push rod 208 is energized to work, driving the connecting block 209. The connecting block 209 moves within the limiting channel 203 and drives the moving seat 202 to move. Due to the limitation of the length of the limiting channel 203, it is ensured that the outer positioning member 4 can be located directly below the cutting member 3, and the positioning member 4 originally located directly below the cutting member 3 can be moved to the outside, thus facilitating the taking and placing operations of the workpiece on the outer positioning member 4. Then, the electric push rod 206 is energized to work, driving the drive motor 304 to move downward. The drive motor 304 is energized to work, driving the limiting cylinder body 303 to rotate. The limiting cylinder body 303 drives the mounting cutter disc 302 to rotate, and the mounting cutter disc 302 drives the cutting tool 301 to rotate. Since the limiting cylinder body 303 and the fitting column 402 are mutually adapted, it can prevent the mounting cutter disc 302 from shifting, thereby improving the accuracy of the deburring operation. The rotating cutting tool 301 realizes the deburring operation on the outer ring of the automotive wheel hub bearing.

[0030] By setting the processing assembly 2, the mutual cooperation between the limiting cylinder body 303 and the fitting column 402 is utilized to improve the cutting accuracy of the cutting tool 301, enhance the refinement of deburring, and improve the quality of the outer ring of the automotive wheel hub bearing; the set protection assembly 1 can increase the safety during the deburring process; the set positioning member 4 can facilitate the taking and placing of workpieces and improve the processing efficiency.

[0031] Working principle: Before processing, install the upper cover plate 103 on the mounting post 205, and install the whole protection component 1 at the front of the processing component 2 to provide a good protection effect for the deburring operation, avoid chip splashing and hurting people, and improve the safety of processing; then place the outer ring of the automotive wheel hub bearing to be processed on the outer positioning member 4. Since there are mounting holes on the outer ring of the automotive wheel hub bearing, it can be adapted to the positioning post 403, so as to fix the outer ring of the automotive wheel hub bearing and prevent it from rotating. Then, the transverse moving push rod 208 is powered on to drive the connecting block 209. The connecting block 209 moves in the limiting channel 203 and drives the moving seat 202 to move. Due to the limitation of the length of the limiting channel 203, it is ensured that the outer positioning member 4 can be located directly below the cutting member 3, and the positioning member 4 originally located directly below the cutting member 3 can be moved to the outside, so as to facilitate the taking and placing operations of the workpiece on the outer positioning member 4. Then, the electric push rod 206 is powered on to drive the driving motor 304 to move down. The driving motor 304 is powered on to drive the limiting cylinder body 303 to rotate. The limiting cylinder body 303 drives the mounting cutter head 302 to rotate. The mounting cutter head 302 drives the cutting tool 301 to rotate. Since the limiting cylinder body 303 and the adapting column 402 are mutually adapted, it can prevent the mounting cutter head 302 from shifting, thus improving the accuracy of the deburring operation. The rotating cutting tool 301 realizes the deburring operation on the outer ring of the automotive wheel hub bearing.
