DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] For example, see Figure 1-Figure 5 , a grinding and polishing device specially used for automobile wheel hub production, comprising: A fixed seat 100, the top of which is equipped with a power gear 200 driven by a servo motor 1, the interior of the fixed seat 100 is rotatably connected with a transmission gear ring 300, the bottom of the transmission gear ring 300 is equipped with a grinding wheel 400 driven by an electric telescopic rod and a servo motor 2, and the side of the fixed seat 100 is equipped with a movable support seat 500; Liquid storage tank 600, the liquid storage tank 600 is installed on the inner side of the fixing seat 100, and the top of the liquid storage tank 600 is equipped with a filter plate 700; The outer side of the output shaft of the power gear 200 is fixedly connected to a hydraulic bin 801, the inner wall of the hydraulic bin 801 is slidably connected to a sliding block 803 via an elastic telescopic rod 802, the side of the hydraulic bin 801 is slidably connected to an arc rod 804, the side of the support seat 500 is equipped with a suction cup 809, and transmission is performed between the arc rod 804 and the suction cup 809 by setting a transmission member. Place the automobile wheel hub between the two support seats 500, and move the support seats 500 to preliminarily clamp the automobile wheel hub. At this time, the suction cup 809 installed on the side of the support seat 500 performs a preliminary adsorption operation on the automobile wheel hub. Subsequently, start the electric telescopic rod and servo motor 2 to drive the grinding wheel 400 to move downward to the specified position and perform corresponding grinding operations. After completing the grinding operation at this location, start servo motor 1 to drive the power gear 200 driven by servo motor 1 to rotate, so that the power gear 200 drives the transmission gear ring 300 meshing with it to rotate, thereby driving the grinding wheel 400 to revolve, and performing corresponding grinding operations on other positions of the automobile wheel hub.

[0022] The transmission part includes a hydraulic device 805, which is assembled on the side of the fixing seat 100 and the top of the supporting seat 500. When the grinding wheel 400 revolves rapidly, that is, the power gear 200 rotates rapidly, the power gear 200 synchronously drives the hydraulic chamber 801 to rotate rapidly, so that the sliding block 803 in the hydraulic chamber 801 stretches the elastic telescopic rod 802 under the action of centrifugal force and slides in the hydraulic chamber 801, so that the pressure in the hydraulic chamber 801 increases, driving the arc rod 804 slidably connected to the hydraulic chamber 801 to move.

[0023] One end of the hydraulic device 805 is slidably connected to a force-bearing rod 806, which is located on the side of the arc rod 804 and in contact with the arc rod 804. The other end of the hydraulic device 805 is slidably connected to a connecting rod 807, and a spring 808 is installed on the side of the force-bearing rod 806. The side of the suction cup 809 is equipped with an air pressure chamber 810, and the air pressure chamber 810 is away from one end of the suction cup 809 and is in a slidably connected state with the air pressure chamber 810. When the arc rod 804 moves, it can squeeze the stress rod 1 806, and the stress rod 1 806 is squeezed and moves, and the stress rod 1 806 slides into the hydraulic device 1 805, so that the pressure in the hydraulic device 1 805 increases, driving the connecting rod 807 slidably connected to the hydraulic device 1 805 to move, so that the connecting rod 807 moves to the side away from the air pressure chamber 810, so that the residual gas in the suction cup 809 is extracted into the air pressure chamber 810 through the air pressure chamber 810. The adsorption effect of the suction cup 809 is improved, and the stability during grinding is improved in this case.

[0024] When the power gear 200 stops rotating, the sliding block 803 loses the centrifugal force, so that the sliding block 803 is reset under the action of the elastic telescopic rod 802. Similarly, the arc rod 804 is reset, and the force-bearing rod 1 806 loses the restriction of the arc rod 804 and can be reset under the action of the spring 1 808, so that part of the gas in the air pressure chamber 810 is reset to the suction cup 809, so as to facilitate the next use of the device.

[0025] An injection assembly 900 for injecting grinding fluid is mounted on the inner side of the fixing seat 100 , and a cleaning assembly 1000 for cleaning the filter plate 700 is mounted on the top of the filter plate 700 .

[0026] When in use, place the automobile wheel hub between the two support seats 500, move the support seats 500 to perform preliminary clamping of the automobile wheel hub, at this time, the suction cup 809 assembled on the side of the support seat 500 performs preliminary adsorption operation on the automobile wheel hub, then, start the electric telescopic rod and servo motor 2, drive the grinding wheel 400 to move downward to the specified position and perform corresponding grinding operation, after completing the grinding operation at that place, start servo motor 1, drive the power gear 200 driven by servo motor 1 to rotate, so that the power gear 200 drives the transmission gear ring 300 meshing with it to rotate, thereby driving the grinding wheel 400 to revolve, and perform corresponding grinding operations on other positions of the automobile wheel hub; when the grinding wheel 400 revolves rapidly, that is, when the power gear 200 rotates rapidly, the power gear 200 synchronously drives the hydraulic chamber 1 801 to rotate rapidly, so that the sliding block 803 in the hydraulic chamber 1 801 stretches the elastic telescopic rod 802 under the action of centrifugal force, and slides in the hydraulic chamber 1 801, so that The pressure in the hydraulic chamber 801 increases, driving the arc rod 804 slidably connected to the hydraulic chamber 801 to move, so that the arc rod 804 squeezes the force-bearing rod 806, and the force-bearing rod 806 is squeezed and moves, and the force-bearing rod 806 slides into the hydraulic device 805, so that the pressure in the hydraulic device 805 increases, driving the connecting rod 807 slidably connected to the hydraulic device 805 to move, so that the connecting rod 807 moves to the side away from the air pressure chamber 810, thereby The remaining gas in the suction cup 809 is extracted into the air pressure chamber 810 through the air pressure chamber 810; when the power gear 200 stops rotating, the sliding block 803 loses the effect of the centrifugal force, so that the sliding block 803 is reset under the action of the elastic telescopic rod 802. Similarly, the arc rod 804 is reset, and the force-bearing rod 806 loses the restriction of the arc rod 804 and can be reset under the action of the spring 808, thereby allowing part of the gas in the air pressure chamber 810 to be reset to the suction cup 809.

[0028] The inside of the delivery bin 904 is respectively equipped with a one-way valve 906 and a one-way valve 907, and the side of the delivery bin 904 is equipped with a nozzle 908. When the moving rod 905 reciprocates in the horizontal direction, the moving rod 905 slides back and forth in the delivery bin 904, and because the outside of the delivery bin 904 is respectively equipped with a one-way valve 906 and a one-way valve 907, the delivery bin 904 sprays the grinding fluid stored in the liquid storage bin 600 through the nozzle 908 and injects it into the grinding wheel 400.
