[0021] The electrical components appearing in the text are all electrically connected with the main controller and 220V mains, and the main controller can be a conventional known device such as a computer for control.

[0022] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figs. 1 to 4 As shown, an automatic feeding device for an automotive wheel hub bearing grinding machine includes a mounting plate 1. A feeding pipe 2 is fixedly inserted into the middle of the mounting plate 1. The feeding pipe 2 is a cylindrical structure with open ends. The inner rings of automotive wheel hub bearings are stacked inside the feeding pipe 2. A discharge control component 3 for supporting the bottom of the lowest automotive wheel hub bearing inner ring is installed on the surface of the mounting plate 1. A clamping and positioning component 4 for limiting the second automotive wheel hub bearing inner ring from the bottom up is also installed on the top surface of the mounting plate 1. More specifically, the inner rings of the automotive wheel hub bearings are stacked inside the feed pipe 2, with the bottom of the feed pipe 2 directly facing the grinding machine's feeding position. The discharge control component 3 supports the bottom of the inner rings of the automotive wheel hub bearings. When feeding is required, the clamping and positioning component 4 clamps and fixes the surface of the second bearing inner ring from bottom to top. Then, the discharge control component 3 operates, releasing the support for the bottommost bearing inner ring. Under the action of gravity, the bearing inner ring will slide down along the inner wall of the feed pipe 2, thereby feeding the surface of the grinding machine. Subsequently, the discharge control component 3 and the clamping and positioning component 4 reset one after another. Under the action of gravity, the remaining inner rings of the automotive wheel hub bearings will fall onto the surface of the discharge control component 3. Repeating the above steps allows for continuous feeding.

[0024] The discharge control assembly 3 includes an electric push rod 301, which is fixedly mounted on the top surface of the mounting plate 1. A traction rod 302 is fixedly connected to the telescopic end of the electric push rod 301, and a bracket 303 is fixedly connected to the end of the traction rod 302. The bracket 303 is movably inserted into the feed pipe 2. It should be noted that the operation of the electric push rod 301 drives the traction rod 302 to move, thereby moving the bracket 303. Ultimately, the top surface of the bracket 303 disengages from the bottom of the inner ring of the automotive wheel hub bearing. Under the action of gravity, the inner ring of the bearing will slide downwards along the inner wall of the feed pipe 2, thereby feeding material onto the surface of the grinding machine.

[0025] The clamping positioning assembly 4 comprises a mounting shell 401, and the mounting shell 401 is fixedly connected with the top surface of the mounting plate 1. A motor 402 is fixedly installed on the left side surface of the mounting shell 401. The output end of the motor 402 is fixedly connected with a double-head screw rod 403. The surface of the double-head screw rod 403 is threadedly connected with two connecting rods 404. A sliding groove 405 is formed through the top surface of the mounting shell 401, and the inner wall of the sliding groove 405 is in sliding connection with the surface of the connecting rod 404. The end portion of the connecting rod 404 is fixedly connected with a clamping block 406, and the clamping block 406 is movably inserted with the surface of the feeding pipe 2. More specifically, the motor 402 is operated to control the double-head screw rod 403 to rotate, so as to drive the connecting rod 404 to slide along the inner wall of the sliding groove 405. The connecting rod 404 will push the sliding groove 405 to move, and the sliding groove 405 can clamp and fix the inner ring of the automobile hub bearing.

[0026] The opposite side surfaces of the two clamping blocks 406 are fixedly connected with anti-skid pads 5, and the anti-skid pads 5 are made of rubber. It should be noted that the anti-skid pads 5 made of rubber increase the friction with the surface of the inner ring of the automobile hub bearing, so that the clamping is more stable.

[0027] The top surface of the bracket 303 is fixedly installed with a pressure sensor 6, and the front surface of the feeding pipe 2 is fixedly installed with an audible and visual alarm 7. More specifically, the pressure sensor 6 can detect the weight of the inner ring of the automobile hub bearing above the bracket 303. When the weight is less than a preset value, the audible and visual alarm 7 can automatically flash and buzz to alarm that the number of the inner ring of the bearing is insufficient, so as to add the inner ring of the bearing into the feeding pipe 2.

[0028] The top of the feeding pipe 2 is threadedly connected with a screw cap 8. The back surface of the mounting plate 1 is fixedly connected with mounting ears 9, and the surface of the mounting ears 9 is formed through with mounting holes. It should be noted that the screw cap 8 can close the top of the feeding pipe 2 to reduce the entry of external sundries into the feeding pipe 2. The mounting ears 9 and the mounting holes are provided to facilitate the fixing of the mounting plate 1 on the surface of the grinding machine by bolts.

[0029] In summary: the inner ring of the automobile hub bearing is stacked in the inside of the feeding pipe 2, the lower part of the feeding pipe 2 is opposite to the feeding position of the grinding machine, the discharging control assembly 3 supports the bottom of the inner ring of the automobile hub bearing, when feeding is needed, the clamping positioning assembly 4 clamps and fixes the surface of the second inner ring of the bearing from bottom to top, then the discharging control assembly 3 operates, the support of the lowermost inner ring of the bearing is released, under the action of gravity, the inner ring of the bearing will slide down along the inner wall of the feeding pipe 2, thereby feeding the surface of the grinding machine, then the discharging control assembly 3 and the clamping positioning assembly 4 reset in turn, under the action of gravity, the remaining inner rings of the automobile hub bearing will fall to the surface of the discharging control assembly 3, the above steps can be repeated to continuously feed, in use, the effect that the surface of the grinding machine is continuously supplied with the inner ring of the bearing is realized, the feeding stability is ensured because the inner ring of the bearing is discharged one by one during the feeding process.

[0030] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application.
