Description

Technical Field

[0001] The present invention relates to the technical field of hub burr grinding, and specifically to a surface burr grinding device for automobile hub processing. Background Art

[0002] A hub is a cylindrical metal component that supports the tire inside the tire profile and is centered on the axle. It is also called a wheel rim, steel rim, wheel, or tire bell. There are many types of hubs according to diameter, width, forming method, and material.

[0003] In the past, the hub bearings of sedans mostly used single-row tapered roller or ball bearings in pairs. With the development of technology, car hub units have been widely used in sedans. A hub is also called a wheel rim.

[0004] There are three manufacturing methods for aluminum alloy hubs: gravity casting, forging, and low-pressure precision casting. The gravity casting method uses gravity to pour the aluminum alloy melt into the mold. After forming, it is processed and polished by a lathe to complete the production. The manufacturing process is relatively simple, does not require precise casting technology, has low cost and high production efficiency, but is prone to bubbles (sand holes), uneven density, and insufficient surface smoothness.

[0005] Currently, when grinding the burrs on the surface of the hub, since the hub has a round shaft structure, it is not easy to fix the hub with a brush during grinding, and the traditional brush is not easy to fit and match with the hub surface, affecting the grinding efficiency. Summary of the Invention

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A surface burr grinding device for automobile hub processing, including a frame plate for stably supporting the grinding component and the hub. Support seats are fixedly installed on both sides of the outer surface of the frame plate, and a cleaning groove is opened at the top of the frame plate;

[0007] A grinding component for polishing the burrs on the hub surface, and the bottom of the grinding component is slidably adapted to a guide rail;

[0008] A positioning and protection component for internally supporting and fixing the hub, and a motor is fixedly installed at the bottom of the positioning and protection component;

[0009] The motor is fixedly installed at the middle of the bottom of the frame plate, and the output end of the motor is fixedly connected to the positioning and protecting part. The positioning and protecting part is rotatably installed above the frame plate. The guide rail is arranged on the surface of the frame plate close to one side of the cleaning groove. There are two groups of grinding assemblies, and the two groups of grinding assemblies are slidably adapted to the frame plate through the guide rail. The staff sleeved the hub on the surface of the positioning and protecting part, so that the positioning and protecting part positions and supports the hub. Then, the staff adjusts the position of the grinding assembly according to the hub shaft diameter so that the grinding assembly fits the surface of the hub. Then, the staff starts the motor, so that the output end of the motor rotates and drives the positioning and protecting part to rotate, so that the hub rotates with the positioning and protecting part and generates friction with the grinding assembly, so as to grind the burrs on the surface of the hub. The burr debris falling off during grinding drops to the surface of the frame plate. When cleaning the frame plate after grinding, the staff sweeps the debris into the cleaning groove to facilitate the collection and cleaning of the debris on the frame plate.

[0010] Among them, the positioning and protecting part includes a through shaft. A shaft rod is rotatably installed at the axis of the through shaft. A mounting plate is fixedly installed on the outer surface of the shaft rod. There are four mounting plates, and the four mounting plates are distributed circumferentially on the surface of the shaft rod. An inner support part is rotatably installed inside each mounting plate, and a bottom steady support part is fixedly installed between the joints of the mounting plates. The staff sleeved the hub on the surface of the shaft rod. At this time, the bottom of the hub is placed above the mounting plate and presses the bottom steady support part. Then, the staff rotates the inner support part upward so that the inner support part supports in the hub cavity to support and position the hub. Then, the staff starts the motor so that the output end of the motor drives the through shaft and the shaft rod to rotate, so that the hub rotates and generates friction with the grinding assembly.

[0011] Preferably, the through shaft is sleeved on the output end of the motor, and the through shaft penetrates through the frame plate and extends to its top. The inner support part is clamped in the hub cavity, and the bottom steady support part is arranged at the bottom of the hub.

[0012] Preferably, the inner support part includes an adjusting block. A cushion block is fixedly installed inside the adjusting block. A clamping block is rotatably installed inside the adjusting block through the cushion block. A fixing rod penetrates through the clamping block. The top of the clamping block is fixedly installed with a clamping rod through the fixing rod. The staff rotates the clamping block so that the clamping block rotates upward inside the cushion block. At this time, the clamping block drives the clamping rod to rotate in the hub cavity until it contacts the inner wall of the hub cavity. The hub is supported and limited by the clamping block and the clamping rod against the two sides of the inner wall of the hub cavity, so as to prevent the hub from shifting when rotating and polishing.

[0013] Preferably, the adjusting block is slidably fitted inside the mounting plate, the adjusting block supports the bottom of the hub, and the cushion block is frictionally fitted with the top of the support plate. The cushion block at the bottom of the clamping block is parallel to the support plate and supports the side of the bottom of the hub to maintain the stability when the hub rotates; the adjusting block and the mounting plate are slidably fitted. When the motor drives the hub to rotate, the adjusting block is thrown outwards due to the inertia generated by the rotation and slides to the outermost side of the mounting plate, making the clamping block in the hub fit more closely with the inner wall of the hub cavity, avoiding loosening of the clamping block and the clamping rod in the hub cavity.

[0014] Preferably, the bottom stabilizing member includes a fixing plate, an installation groove is formed in the inclined surface of the fixing plate, a clamping support block is fixedly installed on the surface of the installation groove, and a cushion plate is sleeved on the outer surface of the clamping support block. Since the middle of the hub is recessed inward, when the hub is sleeved on the surface of the shaft rod and placed above the mounting plate, the middle of the bottom of the hub squeezes the bottom stabilizing member, causing the bottom stabilizing member to be squeezed and recessed downward, so that the bottom stabilizing member is padded under the hub to prevent the hub from shaking during rotation and grinding, which affects the grinding effect.

[0015] Preferably, the fixing plate is fixedly installed on the outer surface of the shaft rod, a bent cover is fixedly installed on the outer surface of the fixing plate, segmented elastic pieces are arranged on the surface of the bent cover, the clamping support block penetrates through the segmented elastic pieces and extends to the outside thereof, and the segmented elastic pieces are in extrusion fit with the cushion plate. The bent cover is squeezed by the hub, recessed downward and squeezes the cushion plate below, and the segmented elastic pieces are deformed according to the shape of the hub, so as to be more suitable for the shape of the middle part of the hub and improve the stability during support.

[0016] Preferably, the grinding assembly includes sliders, there are two sliders, the tops of both sliders are fixedly installed with bottom plates, positioning rods are fixedly installed on both sides of the top of the bottom plates, and a top plate is fixedly installed on the top of the positioning rods. The staff adjusts the position of the sliders in the guide rails according to the shaft diameter of the hub to make the polishing parts fit more closely with the surface of the hub. Then the staff starts the motor, so that the motor rotates to drive the hub to rotate, causing the hub to generate friction with the polishing parts. When the hub rotates, it generates extrusion with the polishing parts, making the polishing parts be squeezed and contact the hub more closely, thereby increasing the contact area with the hub, and strengthening the grinding force when the polishing parts grind the hub.

[0017] Preferably, the sliders are slidably fitted inside the guide rails, polishing parts are fixedly installed at the middle of the bottom of the top plate and the middle of the top of the bottom plate, and the polishing parts are in frictional fit with the surface of the hub.

[0018] Preferably, the polishing member includes mounting blocks. There are two mounting blocks, and elastic bands are fixedly mounted on the surfaces of both mounting blocks. An arc-shaped covering frame is fixedly mounted between the opposite surfaces of the elastic bands. An extrusion fitting block is fixedly mounted on the surface of the arc-shaped covering frame, and a polishing block is fixedly mounted on the surface of the extrusion fitting block. Since the wheel hub has a round shaft structure, it is necessary to fit its surface when polishing it. Before polishing, the staff moves the position of the slider, so that the arc-shaped covering frame moves towards the side close to the wheel hub, and the extrusion fitting block and the polishing block are pressed against the surface of the wheel hub, making the fit closer during polishing, thereby improving the polishing efficiency.

[0019] Preferably, the mounting blocks are respectively arranged at the middle of the bottom of the top plate and the middle of the top of the bottom plate. The extrusion fitting block is arranged in a flexible structure, and the polishing block is frictionally adapted to the surface of the wheel hub.

[0020] The present invention provides a surface burr polishing device for automobile wheel hub processing. It has the following beneficial effects:

[0021] First, for the surface burr polishing device for automobile wheel hub processing, the staff sleeved the wheel hub on the surface of the shaft rod. At this time, the bottom of the wheel hub was placed above the mounting plate and pressed against the bottom steady support member. Then the staff rotated the inner support member upward, so that the inner support member supported in the wheel hub cavity to support and position the wheel hub. Then the staff started the motor, and the output end of the motor drove the through shaft and the shaft rod to rotate, so that the wheel hub rotated and rubbed against the polishing assembly.

[0022] Second, for the surface burr polishing device for automobile wheel hub processing, the staff rotated the clamping block so that the clamping block rotated upward inside the cushion block. At this time, the clamping block drove the clamping rod to rotate in the wheel hub cavity until it contacted the inner wall thereof. The clamping block and the clamping rod abutted against both sides of the inner wall of the wheel hub cavity to support and limit the wheel hub, avoiding the deviation of the wheel hub during rotation and polishing.

[0023] Third, for the surface burr polishing device for automobile wheel hub processing, the cushion block at the bottom of the clamping block is parallel to the frame plate and supports the side of the bottom of the wheel hub to maintain the stability of the wheel hub during rotation; the adjusting block is slidably adapted to the mounting plate. When the motor drives the wheel hub to rotate, the adjusting block is thrown outwards by the inertia generated by the rotation and slides to the outermost side of the mounting plate, making the clamping block inside the wheel hub fit more closely with the inner wall of the wheel hub cavity, avoiding the loosening of the clamping block and the clamping rod in the wheel hub cavity.

[0024] Fourth, for the surface burr polishing device for automobile wheel hub processing, since the middle of the wheel hub is recessed inward, when the wheel hub is sleeved on the surface of the shaft rod and placed above the mounting plate, the middle of the bottom of the wheel hub presses against the bottom steady support member, causing the bottom steady support member to be pressed downward and contract, so that the bottom steady support member is pad under the wheel hub to avoid the shaking of the wheel hub during rotation and polishing, which affects the polishing effect.

[0025] V. For the surface burr grinding equipment for automobile wheel hub processing, the staff adjusts the position of the slider in the guide rail according to the wheel hub shaft diameter, so that the polishing part fits more closely with the wheel hub surface. Then, the staff starts the motor, and the rotation of the motor drives the rotation of the wheel hub, causing friction between the wheel hub and the polishing part. When the wheel hub rotates, it generates extrusion with the polishing part, making the polishing part be extruded and contact the wheel hub more closely, thereby increasing the contact area with the wheel hub, and strengthening the polishing force when the polishing part grinds the wheel hub.

Detailed implementation mode

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0037] The first embodiment is as follows Figures 1 to 5 As shown, the present invention provides a technical solution: a surface burr grinding device for automobile wheel hub processing, including a frame plate 3, which is used to stably support the grinding component and the wheel hub. Support seats 1 are fixedly installed on both sides of the outer surface of the frame plate 3, and a cleaning groove 7 is opened at the top of the frame plate 3;

[0038] A grinding component 4, which is used to polish the burrs on the surface of the wheel hub. The bottom of the grinding component 4 is slidably fitted with a guide rail 2;

[0039] A positioning and protection component 5, which is used to internally support and fix the wheel hub. A motor 6 is fixedly installed at the bottom of the positioning and protection component 5;

[0040] The motor 6 is fixedly installed at the middle of the bottom of the frame plate 3, and the output end of the motor 6 is fixedly connected to the positioning and protection component 5. The positioning and protection component 5 is rotatably installed above the frame plate 3. The guide rail 2 is arranged on the surface of the frame plate 3 close to the cleaning groove 7. There are two groups of grinding components 4, and the two groups of grinding components 4 are slidably fitted with the frame plate 3 through the guide rail 2; The staff sleeved the wheel hub on the surface of the positioning and protection component 5, so that the positioning and protection component 5 positioned and supported the wheel hub. Then, the staff adjusted the position of the grinding component 4 according to the wheel hub shaft diameter so that the grinding component 4 was in contact with the surface of the wheel hub. Then, the staff started the motor 6, so that the output end of the motor 6 rotated and drove the positioning and protection component 5 to rotate, so that the wheel hub rotated with the positioning and protection component 5 and rubbed against the grinding component 4, so that the grinding component 4 polished the burrs on the surface of the wheel hub. The burr debris falling off during grinding dropped onto the surface of the frame plate 3. When cleaning the frame plate 3 after grinding, the staff swept the debris into the cleaning groove 7 to facilitate the collection and cleaning of the debris on the frame plate 3.

[0041] The polishing assembly 4 includes sliders 44. There are two sliders 44. Bottom plates 45 are fixedly installed on the tops of the two sliders 44. Positioning rods 43 are fixedly installed on both sides of the top of the bottom plate 45. A top plate 41 is fixedly installed on the top of the positioning rod 43. The staff adjusts the position of the slider 44 in the guide rail 2 according to the hub shaft diameter, so that the polishing part 42 fits more closely with the hub surface. Then the staff starts the motor 6, so that the rotation of the motor 6 drives the hub to rotate, causing friction between the hub and the polishing part 42. When the hub rotates, it generates extrusion with the polishing part 42, causing the polishing part 42 to be extruded and contact the hub more closely, thereby increasing the contact area with the hub, and strengthening the polishing force when the polishing part 42 polishes the hub.

[0042] The slider 44 is slidably fitted inside the guide rail 2. Polishing parts 42 are fixedly installed at the middle of the bottom of the top plate 41 and the middle of the top of the bottom plate 45. The polishing parts 42 are frictionally fitted with the hub surface.

[0043] The polishing part 42 includes mounting blocks 425. There are two mounting blocks 425. Elastic bands 421 are fixedly installed on the surfaces of the two mounting blocks 425. An arc-shaped covering frame 422 is fixedly installed between the opposite surfaces of the elastic bands 421. Extrusion fitting blocks 424 are fixedly installed on the surface of the arc-shaped covering frame 422. Polishing blocks 423 are fixedly installed on the surface of the extrusion fitting blocks 424. Since the hub is a round shaft structure, it needs to fit with its surface when being polished. Before polishing, the staff moves the position of the slider 44, so that the arc-shaped covering frame 422 displaces towards the side close to the hub, and the extrusion fitting blocks 424 and the polishing blocks 423 generate extrusion with the hub surface, and fit more closely during polishing, thereby improving the polishing efficiency.

[0044] The mounting blocks 425 are respectively arranged at the middle of the bottom of the top plate 41 and the middle of the top of the bottom plate 45. The extrusion fitting blocks 424 are arranged as flexible structures. The polishing blocks 423 are frictionally fitted with the hub surface.

[0045] Second embodiment. On the basis of the first embodiment, please refer to Figures 6 to 7As shown in the figure, the positioning protection member 5 includes a through shaft 54. A shaft rod 51 is rotatably installed at the axis of the through shaft 54. A mounting plate 55 is fixedly installed on the outer surface of the shaft rod 51. There are four mounting plates 55, and the four mounting plates 55 are distributed in a circular shape on the surface of the shaft rod 51. Inner support members 53 are rotatably installed inside the mounting plates 55, and a bottom steady support member 52 is fixedly installed between the joints of the mounting plates 55. The staff sleeved the hub on the surface of the shaft rod 51. At this time, the bottom of the hub was placed above the mounting plate 55 and the bottom steady support member 52 was squeezed. Then the staff rotated the inner support member 53 upward so that the inner support member 53 supported in the hub cavity to support and position the hub. Then the staff started the motor 6 so that the output end of the motor 6 drove the through shaft 54 and the shaft rod 51 to rotate, so that the hub rotated and rubbed against the grinding assembly 4.

[0046] The through shaft 54 is sleeved on the output end of the motor 6, and the through shaft 54 penetrates through the support plate 3 and extends to its top. The inner support member 53 is clamped in the hub cavity, and the bottom steady support member 52 is arranged at the bottom of the hub.

[0047] The inner support member 53 includes an adjustment block 534. A cushion block 535 is fixedly installed inside the adjustment block 534. A clamping block 532 is rotatably installed inside the adjustment block 534 through the cushion block 535. A fixing rod 531 penetrates through the clamping block 532. A clamping rod 533 is fixedly installed at the top of the clamping block 532 through the fixing rod 531. The staff rotated the clamping block 532 so that the clamping block 532 rotated upward inside the cushion block 535. At this time, the clamping block 532 drove the clamping rod 533 to rotate in the hub cavity until it contacted the inner wall thereof. The clamping block 532 and the clamping rod 533 abutted against both sides of the inner wall of the hub cavity to support and limit the hub, avoiding deviation when the hub rotated and was polished.

[0048] The adjustment block 534 is slidably adapted inside the mounting plate 55. The adjustment block 534 supports at the bottom of the hub, and the cushion block 535 is frictionally adapted to the top of the support plate 3. The cushion block 535 at the bottom of the clamping block 532 is in a parallel state with the support plate 3 and supports at the side of the bottom of the hub to maintain the stability when the hub rotates; the adjustment block 534 and the mounting plate 55 are slidably adapted. When the motor 6 drives the hub to rotate, the adjustment block 534 is thrown outward due to the inertia generated by the rotation and slides to the outermost side of the mounting plate 55, making the clamping block 532 inside the hub fit more closely to the inner wall of the hub cavity, avoiding loosening of the clamping block 532 and the clamping rod 533 in the hub cavity.

[0049] Third embodiment. On the basis of the first and second embodiments, please refer to Figures 8 to 9As shown in the figure, the bottom support member 52 includes a fixing plate 521. An installation groove 525 is formed on the inclined surface of the fixing plate 521. A clamping support block 523 is fixedly installed on the surface of the installation groove 525, and a backing plate 524 is sleeved on the outer surface of the clamping support block 523. Since the middle part of the wheel hub is recessed inward, when the wheel hub is sleeved on the surface of the shaft rod 51 and placed above the mounting plate 55, the middle part of the bottom of the wheel hub presses against the bottom support member 52, causing the bottom support member 52 to be squeezed and recessed downward, so that the bottom support member 52 is padded under the wheel hub to prevent the wheel hub from shaking during rotation and grinding, which affects the grinding effect.

[0050] The fixing plate 521 is fixedly installed on the outer surface of the shaft rod 51. A bent cover 522 is fixedly installed on the outer surface of the fixing plate 521. A segmented elastic piece 526 is arranged on the surface of the bent cover 522. The clamping support block 523 penetrates through the segmented elastic piece 526 and extends to its outside. The segmented elastic piece 526 is in extrusion fit with the backing plate 524. The bent cover 522 is squeezed by the wheel hub, recessed downward and squeezes the backing plate 524 below. The segmented elastic piece 526 deforms according to the shape of the wheel hub, so as to fit the shape of the middle part of the wheel hub and improve the stability during support.

[0051] During use, the staff sleeved the wheel hub on the surface of the positioning and protecting member 5, so that the positioning and protecting member 5 positions and supports the wheel hub. Then, the staff adjusted the position of the grinding assembly 4 according to the wheel hub shaft diameter so that the grinding assembly 4 is in contact with the surface of the wheel hub. Then, the staff started the motor 6, so that the output end of the motor 6 rotated and drove the positioning and protecting member 5 to rotate, so that the wheel hub rotated with the positioning and protecting member 5 and rubbed against the grinding assembly 4, so that the grinding assembly 4 ground the burrs on the surface of the wheel hub. The ground burr debris fell onto the surface of the support plate 3. When cleaning the support plate 3 after grinding, the staff swept the debris into the cleaning groove 7 to facilitate the collection and cleaning of the debris on the support plate 3.

[0052] The staff sleeved the wheel hub on the surface of the shaft rod 51. At this time, the bottom of the wheel hub was placed above the mounting plate 55 and pressed against the bottom support member 52. Then, the staff rotated the inner support member 53 upward, so that the inner support member 53 supported in the wheel hub cavity to support and position the wheel hub. Then, the staff started the motor 6, so that the output end of the motor 6 drove the through shaft 54 and the shaft rod 51 to rotate, so that the wheel hub rotated and rubbed against the grinding assembly 4.

[0053] The staff rotated the clamping block 532 so that the clamping block 532 rotated upward inside the cushion block 535. At this time, the clamping block 532 drove the clamping rod 533 to rotate in the wheel hub cavity until it contacted the inner wall thereof. The wheel hub was supported and limited by the clamping block 532 and the clamping rod 533 against the two sides of the inner wall of the wheel hub cavity to prevent the wheel hub from shifting during rotation and polishing.

[0054] The spacer block 535 at the bottom of the clamping block 532 is in a parallel state with the support plate 3 and supports on the bottom side of the hub to maintain the stability during the rotation of the hub; the adjusting block 534 is slidably adapted to the mounting plate 55. When the motor 6 drives the hub to rotate, the adjusting block 534 is thrown outwards due to the inertia generated by the rotation and slides to the outermost side of the mounting plate 55, making the clamping block 532 in the hub fit more closely to the inner wall of the hub cavity, and avoiding the loosening of the clamping block 532 and the clamping rod 533 in the hub cavity.

[0055] Since the middle part of the hub is recessed inwards, when the hub is sleeved on the surface of the shaft rod 51 and placed above the mounting plate 55, the middle part of the bottom of the hub presses on the bottom steady support 52, causing the bottom steady support 52 to be squeezed and recessed downwards, so that the bottom steady support 52 is placed under the hub to prevent the hub from shaking during rotation and grinding, which affects the grinding effect.

[0056] The curved cover 522 is squeezed by the hub, recessed downwards and squeezes the lower cushion plate 524. The segmented elastic piece 526 deforms according to the shape of the hub to facilitate fitting the shape of the middle part of the hub and improve the stability during support.

[0057] The staff adjusts the position of the slider 44 in the guide rail 2 according to the shaft diameter of the hub, making the polishing part 42 fit more closely to the surface of the hub. Then the staff starts the motor 6, so that the motor 6 rotates to drive the hub to rotate, causing the hub to generate friction with the polishing part 42. When the hub rotates, it generates extrusion with the polishing part 42, making the polishing part 42 be squeezed and contact the hub more closely, thereby increasing the contact area with the hub and strengthening the polishing force when the polishing part 42 polishes the hub.

[0058] Since the hub has a round shaft structure and needs to fit its surface during grinding, before grinding, the staff moves the position of the slider 44, making the arc-shaped covering frame 422 displace towards the side close to the hub, and causing the extrusion fitting block 424 and the grinding block 423 to generate extrusion with the surface of the hub, and fitting more closely during grinding, thereby improving the grinding efficiency.

[0059] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
