Description

Technical Field

[0001] The utility model belongs to the field of polishing machine frames, and in particular relates to a polishing machine frame for a wheel hub. Background Art

[0002] In the production of wheel hubs, many burrs, chamfered edges and scales are generated after the wheels are cast. The wheel hubs need to be polished to remove the burrs, chamfered edges and scales to improve the quality of the product. Manual polishing cannot guarantee the processing accuracy of the wheel hubs and the work efficiency is relatively low. At the same time, the metal powder generated during polishing will cause harm to the human body. Therefore, a wheel hub polishing device is needed. The device uses automation to perform end face polishing, side polishing and fine polishing on the wheel hub, improve the polishing quality, save manpower, and prevent the waste powder generated during polishing from causing harm to the construction personnel, thereby ensuring human health.

[0003] The patent application with publication number CN213105997U discloses a car wheel hub polishing device, including: a frame, a moving device, a fixing device, a sliding device, a hydraulic cylinder and a polishing device, wherein the frame is connected to the moving device, the moving device is connected to the fixing device, the sliding device is slidably connected to the frame, one end of the hydraulic cylinder is fixedly connected to the sliding device, the other end of the hydraulic cylinder is fixedly connected to the frame, and the sliding device is connected to the polishing device.

[0004] The above patent fixes the wheel hub by means of a fixing device, and then moves the wheel hub to the bottom of the polishing device by means of a moving device, and polishes the wheel hub by means of the polishing device. However, in this method, loading and unloading of the wheel hub during polishing is difficult, and usually the wheel hub needs to be placed in the fixing device manually, which is troublesome and laborious, resulting in low practicality.

[0005] In summary, the utility model provides a polishing machine frame for a wheel hub to solve the above problems. Utility Model Content

[0031] One aspect of the application of this embodiment is: when the device needs to be used to polish the wheel hub, the wheel hub is first placed on the upper side of the conveyor belt 2, and then the conveyor belt 2 is started. When the conveyor belt 2 conveys the wheel hub to the bottom of the polishing machine 11, the conveyor belt 2 is turned off, and the motor 4 is started. The output end of the motor 4 drives the bidirectional screw 5 to rotate, and then the bidirectional screw 5 is threadedly matched with the two clamps 7 to drive the two clamps 7 to move relatively close until the wheel hub is clamped. Then the first hydraulic rod 9 is started, and one end of the first hydraulic rod 9 drives the telescopic plate 8 to extend and retract, so that the telescopic plate 8 is retracted. Plate 8 drives polisher 11 to move to the appropriate position, and then the lifting assembly 10 is started, and the lifting assembly 10 drives polisher 11 to descend, so that polisher 11 can polish the wheel hub; when polishing is completed, the lifting assembly 10 is started again, and the lifting assembly 10 drives polisher 11 to rise, and the motor 4 is started, and the output end of the motor 4 drives the bidirectional screw 5 to rotate, and the bidirectional screw 5 can drive the two clamps 7 to move relatively away, cancel the clamping of the wheel hub, and start the conveyor belt 2 again to transport and move the polished wheel hub, and complete the polishing operation of the wheel hub. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supply.

[0032] Reference Figure 2-3 In this embodiment, a circular groove 12 is provided in the middle of one side of the bottom plate 1, and one end of the bidirectional screw 5 is rotatably fitted in the circular groove 12.

The two rectangular blocks 701 are respectively threadedly fitted to the circumference of the left-handed screw and the right-handed screw.

[0033] When it is necessary to create or cancel the clamping of the wheel hub, start the motor 4, and the output end of the motor 4 will drive the bidirectional screw 5 to rotate. The left-hand screw and the right-hand screw in the bidirectional screw 5 will simultaneously cooperate with the two rectangular blocks 701 threads, so that the two rectangular blocks 701 are relatively close to or away from each other, and then the two rectangular blocks 701 synchronously drive the two arc plates 702 to be relatively close to or away from each other, so that the inner walls of the two arc plates 702 will create or cancel contact with the peripheral side of the wheel hub, and create or cancel the clamping relationship with the wheel hub.

One side of the first hydraulic rod 9 is fixed to the other end of the upper side of the frame 3, and one end of the first hydraulic rod 9 is fixed to one end of the slide plate 802 and inside one end of the fixed plate 801, thereby changing the position of the slide plate 802 and changing the position of the slide plate 802 fixed to the lower side of the slide plate 802.

[0035] When the telescopic plate 8 needs to be used to adjust the left and right position of the polishing machine 11, the first hydraulic rod 9 is started, and the output end of the first hydraulic rod 9 will drive the slide plate 802 to slide and fit inside one end of the fixed plate 801, thereby changing the position of the slide plate 802 and simultaneously changing the position of the lifting assembly 10 and the polishing machine 11 on the lower side of the slide plate 802.

[0036] Reference Figure 2-3 The lifting assembly 10 of this embodiment includes a second hydraulic rod 101 fixed to the middle of the lower side of the slide 802, a connecting plate 102 fixed to the lower end of the second hydraulic rod 101, and two telescopic rods 103 fixed between the upper side of the connecting plate 102 and the lower side of the slide 802. The two telescopic rods 103 are located on opposite sides of the second hydraulic rod 101, and the polishing machine 11 is fixed to the middle of the lower surface of the connecting plate 102.

[0037] When the lifting assembly 10 needs to be used to control the height of the polishing machine 11, the second hydraulic rod 101 is started, and the output end of the second hydraulic rod 101 drives the connecting plate 102 to be lifted and lowered. At the same time, the two telescopic rods 103 will be lifted and lowered synchronously with the height of the connecting plate 102, and the connecting plate 102 can drive the polishing machine 11 fixed on the lower side of the connecting plate 102 to be lifted and lowered.
