Description

Technical Field

[0001] The invention belongs to the technical field of wheel hub processing, and in particular relates to wheel hub grinding processing equipment. Background Art

[0002] The wheel hub is a metal component that supports the tire. There are many types of wheels on the market, and the sizes of different wheels vary greatly. Among them, alloy wheels have the advantages of good heat dissipation, light weight, and more beautiful appearance. At present, common wheel hub manufacturing methods can be roughly divided into casting and forging. The casting method uses gravity to pour the metal solution into the mold. The metal solution is formed into a wheel hub blank in the mold. After the wheel hub blank is cast, the inner and outer side walls of the wheel hub blank need to be polished so that the roughness of the inner and outer side walls of the wheel hub meets the requirements, thereby facilitating subsequent further processing.

[0003] In the prior art, the grinding of the inner and outer walls of the wheel hub blank is mostly achieved with the help of grinding machines. The existing grinding machines mostly grind the inner and outer walls of the wheel hub blank separately, that is, first use the clamping mechanism to clamp the outer wall of the wheel hub blank, and then use the grinding mechanism to extend into the inner side of the wheel hub blank to grind the inner wall of the wheel hub blank. After the inner wall of the wheel hub blank is ground, the clamping mechanism is used to clamp the inner wall of the wheel hub blank, and then the grinding mechanism is extended to the outside of the wheel hub blank to grind the outer wall of the wheel hub blank. This grinding method is relatively traditional. On the one hand, the grinding steps of the inner and outer walls of the wheel hub blank are relatively cumbersome, resulting in relatively low grinding efficiency. On the other hand, when the clamping mechanism clamps the inner wall of the wheel hub blank that has been ground, it is easy to cause damage to the inner wall of the wheel hub blank, thereby affecting the previous grinding effect.

[0043] See also Figure 1 、 Figure 2 as well as Figure 3The present embodiment provides a wheel hub grinding and processing equipment, including a support platform 10, a rotating rod 20, a clamping assembly 30, a driving assembly 40, a first grinding assembly 50, a second grinding assembly 60 and a motor 70, wherein the motor 70 is fixedly mounted on the bottom of the support platform 10, one end of the rotating rod 20 is connected to the output end of the motor 70, and the other end extends above the support platform 10, the clamping assembly 30 is mounted on the outside of the rotating rod 20, and is used to clamp the wheel hub 80 on the rotating rod 20, the first grinding assembly 50 and the second grinding assembly 60 are arranged on the side of the rotating rod 20, and the The first grinding assembly 50 and the second grinding assembly 60 are arranged opposite to each other, and the driving assembly 40 is arranged outside the rotating rod 20. When the inner wall of the wheel hub 80 needs to be ground, the driving assembly 40 is used to drive the first grinding assembly 50 and the second grinding assembly 60 to move in one direction so that the first grinding assembly 50 contacts the inner wall of the wheel hub 80. When the outer wall of the wheel hub 80 needs to be ground, the driving assembly 40 is used to drive the first grinding assembly 50 and the second grinding assembly 60 to move in another direction so that the second grinding assembly 60 contacts the outer wall of the wheel hub 80.

[0044] When the wheel hub 80 needs to be polished, the wheel hub 80 to be polished can be placed on the outside of the rotating rod 20, and the wheel hub 80 and the rotating rod 20 can be clamped together by the clamping assembly 30. After the wheel hub 80 is clamped, the first polishing assembly 50 and the second polishing assembly 60 are respectively located on the inner and outer sides of the wheel hub 80, and then the rotating rod 20 is driven by the motor 70 to rotate forward, thereby driving the wheel hub 80 to rotate forward, and at the same time, the driving assembly 40 is used to drive the first polishing assembly 50 and the second polishing assembly 60 to move in one direction, so that the first polishing assembly 50 and the second polishing assembly 60 can be moved in one direction. The grinding assembly 50 contacts the inner wall of the wheel hub 80, and the relative rotation between the first grinding assembly 50 and the wheel hub 80 is used to achieve the grinding of the inner wall of the wheel hub 80. When the inner wall of the wheel hub 80 is ground, the driving assembly 40 drives the first grinding assembly 50 and the second grinding assembly 60 to move in another direction, thereby separating the first grinding assembly 50 from the inner wall of the wheel hub 80. At the same time, the second grinding assembly 60 contacts the outer wall of the wheel hub 80, and the relative rotation between the second grinding assembly 60 and the wheel hub 80 is used to achieve the grinding of the outer wall of the wheel hub 80.

[0045] See also Figure 4 as well as Figure 5 In one embodiment, an external thread 201 is provided on the outer wall of one end of the rotating rod 20 away from the motor 70, and the clamping assembly 30 includes a support block 301 and a pressure ring 302. The support block 301 is fixedly arranged on the outside of the rotating rod 20, and the inner wall of the pressure ring 302 is provided with an internal thread that is compatible with the external thread 201.

[0046] When the wheel hub 80 needs to be polished, the wheel hub 80 can be placed outside the rotating rod 20 so that the rotating rod 20 passes through the axial hole in the middle of the wheel hub 80, and then the pressure ring 302 is screwed onto the outside of the rotating rod 20. The internal thread on the inner wall of the pressure ring 302 and the external thread on the outer wall of the rotating rod 20 cooperate to press the wheel hub 80 onto the support block 301 to fix the wheel hub 80 and the rotating rod 20 as a whole, so that when the motor 70 drives the rotating rod 20 to rotate, it can drive the wheel hub 80 to rotate synchronously.

[0047] See also Figure 3 as well as Figure 6 In one embodiment, the driving assembly 40 includes a turntable 401, which is fixedly arranged on the outer wall of the rotating rod 20. A second annular groove 403 and a guide bevel 404 are provided on the upper surface of the turntable 401. The second annular groove 403 is concentrically arranged with the turntable 401, and one end of the guide bevel 404 is connected to the second annular groove 403. The first grinding assembly 50 includes a first arc-shaped grinding sheet 501 and a support rod 503. One end of the support rod 503 is fixedly connected to the first arc-shaped grinding sheet 501, and the other end extends above the turntable 401. A sliding pin 504 is fixedly provided at the bottom position of one end of the support rod 503 located above the turntable 401. The support rod 503 is slidably mounted on the upper part of the support platform 10, and the lower end of the sliding pin 504 extends into the inside of the guide bevel 404.

[0048] Initially, the lower end of the sliding pin 504 extends to the inside of the guide inclined groove 404. After the wheel hub 80 is fixed to the outside of the rotating rod 20, the first arc-shaped grinding sheet 501 is located on the inner side of the wheel hub 80 and does not contact the inner wall of the wheel hub 80. When the motor 70 drives the rotating rod 20 to rotate forward and then drives the wheel hub 80 to rotate forward, the rotating rod 20 can drive the turntable 401 to rotate forward. When the turntable 401 rotates forward, the guide inclined groove 404 can push the sliding pin 504, thereby causing the sliding pin 504 to slide from the guide inclined groove 404 into the inside of the second annular groove 403. During this process, the sliding pin 504 Push the support rod 503 so that the support rod 503 slides along the upper part of the support platform 10, and then push the first arc-shaped grinding sheet 501 so that the first arc-shaped grinding sheet 501 contacts the inner wall of the rotating wheel hub 80. After the first arc-shaped grinding sheet 501 contacts the inner wall of the wheel hub 80, as the turntable 401 continues to rotate, the sliding pin 504 slides along the inside of the second annular groove 403. Since the second annular groove 403 is concentrically arranged with the turntable 401, the first arc-shaped grinding sheet 501 can maintain contact with the inner wall of the wheel hub 80, thereby comprehensively grinding the inner wall of the wheel hub 80.

[0049] See also Figure 3 as well as Figure 6In one embodiment, the upper surface of the turntable 401 is further provided with a first annular groove 402, the first annular groove 402 is located inside the first annular groove 403, the first annular groove 402 and the second annular groove 403 are arranged concentrically, the end of the guide bevel 404 away from the second annular groove 403 is connected to the first annular groove 402, and the two ends of the guide bevel 404 are respectively connected to the first annular groove 402 and the second annular groove 403. The positions are both rotatably provided with reversing blocks 405, and one side of the two groups of reversing blocks 405 are connected to the The turntable 401 is connected, and the first elastic member 407 is used to provide elastic tension to the reversing block 405, so that the two groups of the reversing blocks 405 extend into the first annular groove 402 and the second annular groove 403 respectively. The second grinding assembly 60 includes a second arc-shaped grinding sheet 601 and a connecting base plate 602. The second arc-shaped grinding sheet 601 is arranged on the outside of the first arc-shaped grinding sheet 501. One end of the connecting base plate 602 is fixedly connected to the bottom of the second arc-shaped grinding sheet 601, and the other end is fixedly connected to the bottom of the first arc-shaped grinding sheet 501.

[0050] When the wheel hub 80 is fixed to the outside of the rotating rod 20, the first arc-shaped grinding sheet 501 is located on the inner side of the wheel hub 80 and does not contact the inner wall of the wheel hub 80. At the same time, the second arc-shaped grinding sheet 601 is located on the outer side of the wheel hub 80 and does not contact the outer wall of the wheel hub 80. During the process of the first arc-shaped grinding sheet 501 grinding the inner wall of the wheel hub 80, the sliding pin 503 always slides forward along the inside of the second annular groove 403. When the sliding pin 503 slides forward to the position connected with the guide bevel groove 404, the sliding pin 503 can push the reversing block 405 extending into the inside of the second annular groove 403, so that the reversing block 405 is deflected into the inside of the guide bevel groove 404, thereby connecting the guide bevel groove 404 with the second annular groove 404. 03 is closed to prevent the sliding pin 503 from sliding into the guide inclined groove 404, thereby ensuring that the sliding pin 503 can continue to slide forward along the second annular groove 403; after the first arc-shaped grinding disc 501 finishes grinding the inner wall of the wheel hub 80, the motor 70 drives the rotating rod 20 to rotate in the opposite direction, thereby driving the wheel hub 80 and the turntable 401 to rotate in the opposite direction. When the turntable 401 rotates in the opposite direction, the sliding pin 504 slides in the opposite direction along the second annular groove 403. When the sliding pin 504 slides in the opposite direction to the connecting portion between the second annular groove 403 and the guide inclined groove 404, the sliding pin 504 can act on the reversing block 405 extending into the second annular groove 403. The reversing block 405 The sliding pin 504 is guided into the interior of the guide inclined groove 404, and then the guiding inclined groove 404 pushes the sliding pin 504 into the interior of the first annular groove 402. When the sliding pin 504 enters the interior of the first annular groove 402, it can pull the support rod 503 and make the support rod 503 slide in the opposite direction compared to the upper part of the support platform 10, thereby pulling the first arc-shaped grinding sheet 501 so that the first arc-shaped grinding sheet 501 is away from the inner wall of the wheel hub 80. When the first arc-shaped grinding sheet 501 is away from the inner wall of the wheel hub 80, the second arc-shaped grinding sheet 601 can be pulled by the connecting base plate 602 so that the second arc-shaped grinding sheet 601 contacts the outer wall of the wheel hub 80. Since the wheel hub 80 is in a reverse rotation state at this time, the second arc-shaped grinding sheet 501 is The blade 601 can be used to grind the outer wall of the hub 80. During the process of the second arc-shaped grinding blade 601 grinding the outer wall of the hub 80, the sliding pin 503 always slides in the opposite direction along the inside of the first annular groove 402. When the sliding pin 503 slides in the opposite direction to the position connected with the guide bevel groove 404, the sliding pin 503 can push the reversing block 405 extending into the inside of the first annular groove 402, so that the reversing block 405 is deflected into the inside of the guide bevel groove 404, thereby closing the connection between the guide bevel groove 404 and the first annular groove 402, thereby preventing the sliding pin 503 from sliding into the inside of the guide bevel groove 404, thereby ensuring that the sliding pin 503 can continue to slide in the positive direction along the inside of the first annular groove 402.After the inner and outer walls of the hub 80 have been polished, the motor 70 drives the rotating rod 20 and the rotating disk 401 to rotate forward again. When the rotating disk 401 rotates forward, the sliding pin 504 can be guided into the guide chute 404 by the reversing block 405 extending into the first annular groove 402. Then, the first curved grinding plate 501 and the second curved grinding plate 601 are pushed again through the support rod 503, so that the second grinding plate 601 is separated from the outer wall of the hub 80. When the second grinding plate 601 is separated from the outer wall of the hub 80 and the first curved grinding plate 501 is no longer in contact with the inner wall of the hub 80, the motor 70 stops running, and the pressure ring 302 is immediately detached from the outside of the rotating rod 20. The hub 80 can then be removed from the outside of the rotating rod 20.

[0051] See also Figure 6 In one embodiment, the two sets of reversing blocks 405 are rotatably connected to the inner bottom wall of the guide inclined groove 404 through a rotating pin 406.

[0052] See also Figure 7 In one embodiment, a guide rail 103 is fixedly provided on the upper portion of the support platform 10, a slide bar 505 is fixedly provided on the bottom of the support rod 503, a slider 507 is fixedly provided on the bottom of the slider 505, and the slider 507 slides with the guide rail 103.

[0053] When the turntable 401 rotates forward so that the guide bevel 404 pushes the sliding pin 504 into the second annular groove 403, the sliding pin 504 pushes the support rod 503 and the sliding rod 505 so that the slider 507 slides along the guide rail 103. When the turntable 401 rotates reversely so that the guide bevel 404 pushes the sliding pin 504 into the first annular groove 402, the sliding pin 504 pulls the support rod 503 and the sliding rod 505 so that the slider 507 slides reversely along the guide rail 103. Through the sliding cooperation between the slider 507 and the guide rail 103, sliding support can be provided for the movement of the support rod 503, the first arc-shaped grinding sheet 501 and the second arc-shaped grinding sheet 601, so that the first grinding sheet 501 and the second grinding sheet 601 can be in stable contact with the side wall of the wheel hub 80, thereby improving the grinding effect of the wheel hub 80.

[0054] In one embodiment, the guide rail 103 and the support rod 503 are parallel to each other, and both the guide rail 103 and the support rod 503 are arranged along the radial direction of the turntable 401 .

[0055] See also Figure 7 In one embodiment, a stopper 102 is fixedly provided on the upper portion of the support platform 10 at one end of the guide rail 103 , and one side of the slide rod 505 is connected to the stopper 102 via a second elastic member 506 .

[0056] When the turntable 401 rotates in the reverse direction so that the sliding pin 503 slides to the position where the second annular groove 403 and the guide inclined groove 404 are connected, on the one hand, the sliding pin 504 is guided into the guide inclined groove 404 by the reversing block 405 extending into the second annular groove 403. On the other hand, the elastic pulling force of the second elastic member 506 on the sliding rod 505 is used to pull the sliding pin 504 into the guide inclined groove 404, thereby improving the auxiliary reversing of the sliding pin 504. Similarly, when the turntable 401 rotates in the forward direction so that the sliding pin 503 slides to the position where the first annular groove 402 and the guide inclined groove 404 are connected, on the one hand, the reversing block 405 extending into the first annular groove 402 is used to guide the sliding pin 504 into the guide inclined groove 404. On the other hand, the elastic supporting effect of the second elastic member 506 on the sliding rod 505 is used to push the sliding pin 504 into the guide inclined groove 404, thereby improving the auxiliary reversing of the sliding pin 504.

[0057] In one embodiment, the first elastic member 407 and the second elastic member 506 can be springs or metal springs, which are not limited here.

[0058] See also Figure 1 、 Figure 2 as well as Figure 3 In one embodiment, a plurality of legs 101 are fixedly provided on the bottom edge of the support platform 10, and an inclined reinforcement rod 502 is fixedly provided on the upper part of the support rod 503. The end of the reinforcement rod 502 away from the support rod 503 is fixedly connected to the first arc-shaped grinding sheet 501. The reinforcement rod 502 is used to provide inclined support for the first arc-shaped grinding sheet 501, thereby improving the stability of the first arc-shaped grinding sheet 501 and further improving the grinding effect of the inner wall of the wheel hub 80.

[0059] The working principle of the present invention is as follows:

[0060] First, the staff puts the wheel hub 80 to be polished on the outside of the rotating rod 20, and then presses the wheel hub 80 on the upper part of the support block 301 with the help of the thread cooperation between the pressure ring 302 and the external thread 201, thereby fixing the wheel hub 80 and the rotating rod 20 as a whole. Then, the staff starts the motor 70, so that the motor 70 drives the rotating rod 20 to rotate forward, and the rotating rod 20 drives the wheel hub 80 and the rotating disk 401 to rotate forward. When the rotating disk 401 rotates forward, the sliding pin 504 is pushed into the guide inclined groove 404. Located inside the second annular groove 403 on the outside, during this process, the sliding pin 504 pushes the support rod 503 and then pushes the first arc-shaped grinding disc 501 to move outward, so that the first arc-shaped grinding disc 501 contacts the inner wall of the forward-rotating wheel hub 80, and then grinds the inner wall of the wheel hub 80; when the inner wall of the wheel hub 80 is polished, the motor 70 drives the rotating rod 20, the wheel hub 80 and the turntable 401 to rotate in the opposite direction, and when the sliding pin 504 slides along the inside of the second annular groove 403 to the guide inclined groove 404 When in the connected position, the reversing block 405 extending into the second annular groove 403 guides the sliding pin 504 into the guide bevel groove 404, and the guide bevel groove 404 then pushes the sliding pin 504 into the inner first annular groove 402. During this process, the sliding pin 504 pulls the support rod 503, thereby moving the first arc-shaped grinding sheet 501 away from the inner wall of the hub 80, and at the same time, the second arc-shaped grinding sheet 601 contacts the outer wall of the hub 80 rotating in the opposite direction, thereby grinding the outer wall of the hub 80. When the inner and outer walls of the wheel hub 80 are polished, the motor 70 drives the rotating rod 20 and the turntable 401 to rotate forward again. When the turntable 401 rotates forward, the reversing block 405 extending into the first annular groove 402 pushes the sliding pin 504 into the guide inclined groove 404. The sliding pin 504 pushes the second arc-shaped polishing sheet 601 away from the outer wall of the wheel hub 80, and then stops the operation of the motor 70. Then, the pressure ring 302 is detached from the outside of the rotating rod 20, and the wheel hub 80 is removed from the outside of the rotating rod 20.

[0061] In the embodiment of the present invention, when the wheel hub 80 needs to be polished, the wheel hub 80 to be polished can be placed on the outside of the rotating rod 20, and the wheel hub 80 and the rotating rod 20 can be clamped as a whole by using the clamping assembly 30. After the wheel hub 80 is clamped, the first polishing assembly 50 and the second polishing assembly 60 are respectively located on the inner and outer sides of the wheel hub 80, and then the rotating rod 20 is driven by the motor 70 to rotate forward, thereby driving the wheel hub 80 to rotate forward, and at the same time, the driving assembly 40 is used to drive the first polishing assembly 50 and the second polishing assembly 60 to move in one direction, so that the first polishing assembly 50 contacts the inner wall of the wheel hub 80, and the first polishing assembly 50 is used to polish the wheel hub 80. The relative rotation between the grinding assembly 50 and the wheel hub 80 realizes the grinding of the inner wall of the wheel hub 80. When the inner wall of the wheel hub 80 is ground, the driving assembly 40 drives the first grinding assembly 50 and the second grinding assembly 60 to move in another direction, thereby separating the first grinding assembly 50 from the inner wall of the wheel hub 80, and at the same time, the second grinding assembly 60 contacts the outer wall of the wheel hub 80. The relative rotation between the second grinding assembly 60 and the wheel hub 80 realizes the grinding of the outer wall of the wheel hub 80. Compared with the existing technology, it can automatically grind the inner and outer walls of the wheel hub 80, and has the advantages of good grinding effect and high grinding efficiency.
