[0002] The wheel hub is the part in the center of the wheel where the axle is installed. The wheel hubs on the market can be divided into steel wheel hubs and alloy wheel hubs according to their materials. The main advantages of steel wheel hubs are simple manufacturing process, relatively low cost, and strong resistance to metal fatigue. The thermal conductivity of alloy wheel hubs is about three times that of steel, and they have good heat dissipation. They can play a certain role in the thermal attenuation of the vehicle's braking system, tires and braking system. However, no matter what material the wheel hub is made of, in order to ensure a high surface smoothness during manufacturing, some commonly used deburring devices are generally used to remove burrs.

[0003] According to the Chinese utility model disclosure CN219310889U, a deburring device for automobile wheel hub production is disclosed. Its technical solution includes: a bottom plate, a support plate, a screw body, a fixed plate and a slider, a support frame is installed on one side of the upper outer wall of the bottom plate, a first electric push rod is arranged on both sides of the upper outer wall of the support frame, a fixed plate is installed on the lower outer wall of the first electric push rod, a rotating shaft is rotatably installed inside the fixed plate, a support plate is installed on the lower outer wall of the rotating shaft, a sliding groove is opened on both sides of the lower outer wall of the support plate, a slider is slidably installed inside the sliding groove, and a connecting plate is installed on the lower outer wall of the slider, and by arranging the fixed plate, the support plate and the connecting plate, the effect of improving the processing efficiency of the workpiece is achieved, the comprehensiveness of the grinding of the outer wall of the wheel hub is guaranteed, and the grinding efficiency of the wheel hub is improved.

[0004] The above-mentioned patent can realize the simultaneous grinding of the outer wall and the top wall of the wheel hub, but when it is necessary to grind the bottom surface of the wheel hub, it is necessary to first release the fixation of the wheel hub, turn the wheel hub over, and then grind the bottom surface. The operation is relatively complicated and is not conducive to improving the efficiency of deburring the wheel hub. Utility Model Content

The side grinding mechanism 27 includes: a motor 271, which is rotatably connected to the left side wall of the grinding disc 26, and the output shaft of the motor 271 penetrates and extends into the inside of the grinding disc 26; a gear 272, which is rotatably connected to the inside of the grinding disc 26, and the gear 272 is fixedly connected to the output shaft of the motor 271; an upper rack 273, which is slidably connected to the inside of the grinding disc 26 and meshes with the top of the gear 272; a lower rack 274, which is slidably connected to the inside of the grinding disc 26 and meshes with the bottom of the gear 272; a moving plate 276, which is arranged on the outer side wall of the lower rack 274, and a through slot for the moving plate 276 to move is provided on the grinding disc 26; a bracket 278, which is arranged on the outer side wall of the upper rack 273, and the bottom of the bracket 278 is provided with the moving plate 276; and a grinding block 277, which is arranged on the opposite surface of the moving plate 276. The fixed plate 23 and the grinding block 277 have arc surfaces.

[0045] Before grinding, the wheel hub is set on two fixing plates 23, and the motor 221 is started. The motor 221 drives the bidirectional screw 22 to rotate. The threaded block 222 threadedly connected on the bidirectional screw 22 drives the fixing plates 23 to approach or depart from each other according to the different directions. After controlling the rotation direction and number of revolutions of the motor 221, the fixing plate 23 is brought close to the inner wall of the wheel hub, and the wheel hub is fixed. Then, the grinding assembly 2 is used to grind and remove burrs on the wheel hub: the staff first controls the electric push rod 25 to push the grinding disc 26 to move toward the wheel hub until one side of the grinding disc 26 is close to the left side wall of the wheel hub, and then uses the side grinding mechanism 27 to bring the grinding block 277 close to the side of the wheel hub. Side: Start the motor 3 271, the motor 3 271 drives the gear 272 to rotate, when the gear 272 rotates, the upper rack 273 and the lower rack 274 meshed at two places drive the front side moving plate 276 to approach each other, until the grinding block 277 on the opposite surface of the moving plate 276 is close to the side of the hub, at this time, the operation before grinding is completed, and then start the motor 1 211, the motor 1 211 drives the turntable 21 and the hub fixed on the turntable 21 to rotate, when the hub rotates, the scraper 24 and the grinding disc 26 grind the surfaces of both sides of the hub, and the grinding block 277 grinds the side of the hub, so that the hub can be polished at multiple locations at the same time, and the efficiency of grinding and deburring the hub is improved. The arc surface on the fixed plate 23 increases its contact area with the inner wall of the hub, increases the stability of the hub fixation, and the arc surface on the grinding block 277 makes the grinding block 277 fit the depression on the side of the hub more closely, and the grinding effect is better.

[0046] Embodiment 2

[0047] On the basis of the first embodiment, an auxiliary function is added.

[0048] See also Figure 1-4 The two square through grooves on the rotating disk 21 and the grinding disk 26 are provided with telescopic shells 3, and the fixed plate 23 and the movable plate 276 both penetrate the telescopic shell 3. The outer wall of the fixed plate 23 is provided with an anti-slip pad 231. The upper rack 273 and the lower rack 274 are both provided with a limit rod 275 on the facing surface, and the limit rod 275 is located at both ends of the upper rack 273 and the lower rack 274.

[0049] The telescopic shell 3 blocks the through slots for the fixed plate 23 and the movable plate 276 on the turntable 21 and the grinding disc 26 to prevent the waste generated during grinding from entering the through slots and affecting the use of the bidirectional screw 22 and the gear 272. The anti-skid pad 231 increases the friction after the fixed plate 23 contacts the inner wall of the hub, increases the stability of the hub after being fixed, and prevents the hub from shifting during rotation and grinding. The limit rod 275 limits the distance that the upper rack 273 and the lower rack 274 drive the movable plate 276 to move. When the upper rack 273 and the lower rack 274 move outward to a certain distance, the limit rod 275 contacts the gear 272, and the gear 272 cannot continue to rotate, thereby preventing the movable plate 276 from continuing to move in linkage, thereby preventing the upper rack 273 and the lower rack 274 from moving too far and losing the meshing state with the gear 272, thereby affecting the use.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
