Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0041] As previously mentioned, vehicle tires tend to generate a lot of noise during normal driving. Therefore, in order to reduce the noise generated by the tires and to reduce the cost of silent tires, low-cost silent tires are made by attaching silent cotton to the outer periphery of the rim. The main working method of the current tooling for attaching silent cotton to the rim is to fit the rim onto a turntable, then rotate the turntable so that the rim rotates relative to the roller. The roller can roll the silent cotton outside the rim as the rim rotates, so that the silent cotton is attached to the rim. Because the turntable has a constant size, it cannot be used for rims of different diameters, resulting in low versatility of the tooling for attaching silent cotton to the rim.

[0042] Reference Figure 1 、 Figure 2 , Figure 1 and Figure 2 The following are the structural diagram and exploded diagram of the tooling for attaching rim silent cotton according to the embodiment of the present invention. As shown in the figure, in this embodiment, the tooling for attaching rim silent cotton includes a workbench 100, a first bearing assembly 200, a second bearing assembly 300 and a rolling assembly 400. The first bearing assembly 200 and the second bearing assembly 300 are arranged side by side and spaced apart, and the first bearing assembly 200 and the second bearing assembly 300 are both arranged on the workbench 100. When assembling the rim 500 to be processed, the wheel rim 510 of the rim 500 to be processed abuts against the outer peripheral surfaces of the first bearing assembly 200 and the second bearing assembly 300, so that the first bearing assembly 200 and the second bearing assembly 300 can support the rim 500 to be processed. The processed rim 500, the rim 500 to be processed can rotate relative to the first bearing assembly 200 and the second bearing assembly 300, the rolling assembly 400 is installed on the workbench 100, and the rolling assembly 400 is used to roll the silent cotton 600 outside the rim 500 to be processed when the rim 500 to be processed rotates, so that the silent cotton 600 can be attached to the rim 500, the first bearing assembly 200 and the second bearing assembly 300 can support the wheel rim 510 of rims 500 of different diameters to adapt to rims 500 of different diameters, thereby improving the versatility of the tooling used to attach the rim silent cotton.

[0043] For example, when attaching the silent cotton 600 to the rim 500 to be processed, the rim 500 to be processed is placed on the first supporting assembly 200 and the second supporting assembly 300, so that the rim 510 of the rim 500 to be processed is in contact with the outer peripheral surface of the first supporting assembly 200 and the outer peripheral surface of the second supporting assembly 300. At this time, the rolling assembly 400 is spaced apart from the rim 500 to be processed. Thereafter, one end of the silent cotton 600 is attached to the outer side of the rim 500, and the rim 500 to be processed is rotated. The rolling assembly 400 can roll the silent cotton 600 so that the silent cotton 600 is attached to the outer side of the rim 500. The first supporting assembly 200 and the second supporting assembly 300 can support the rim 510 of rims 500 of different diameters to adapt to rims 500 of different diameters, thereby improving the versatility of the tooling used to attach the rim silent cotton.

[0044] It should be noted that along the axial direction of the rim 500, the rim 500 has two rims 510 arranged at intervals. Among the two rims 510, one is located on the inner side of the rim 500 and the other is located on the outer side of the rim 500. When the tire is mounted on the rim 500, the two rims 510 can limit the movement of the tire along the axial direction of the rim 500, which will not be described in detail here.

[0045] It should be noted that by setting up a rolling assembly 400, the rolling assembly 400 itself can be used to apply pressure to the silent cotton 600 during the processing process, without the need for manual pressure by staff, and the distance between the roller 420 in the rolling assembly 400 and the outer peripheral surface of the rim 500 is fixed, so that the roller 420 can apply uniform pressure to the silent cotton 600, ensuring that all positions of the silent cotton 600 are attached to the outer peripheral surface of the rim 500.

[0046] It should be noted that the first supporting assembly 200, the second supporting assembly 300, and the rolling assembly 400 are each configured in two groups, with the first supporting assembly 200, the second supporting assembly 300, and the rolling assembly 400 corresponding one to one, enabling simultaneous processing of two rims 500. Of course, in some specific embodiments, the first supporting assembly 200, the second supporting assembly 300, and the rolling assembly 400 may also be configured in one, three, or four groups, etc., without limitation herein.

[0047] Reference Figure 3 、 Figure 4 , Figure 3 This is a structural diagram of the first load-bearing assembly 200 or the second load-bearing assembly 300 according to an embodiment of the present invention. Figure 4The figure is a front view of the first bearing assembly 200 or the second bearing assembly 300 according to an embodiment of the present invention. As shown in the figure, in this embodiment, the first bearing assembly 200 includes a first bearing portion and a second bearing portion, which are arranged side by side and spaced apart along the axial direction of the rim 500 so that the first bearing portion and the second bearing portion can respectively abut against the corresponding wheel rim 510 of the rim 500. On the one hand, the material cost of the first bearing assembly 200 can be reduced, thereby reducing the production cost of the tooling for attaching the rim silent cotton. On the other hand, a first avoidance channel is formed between the first bearing portion and the second bearing portion. The first avoidance channel can avoid the silent cotton 600, so that one end of the silent cotton 600 can enter the gap between the first bearing assembly 200 and the outer peripheral surface of the rim 500, which can facilitate the attachment of the silent cotton 600 to the outer peripheral surface of the rim 500.

[0048] In this embodiment, the first supporting portion includes a first support 210 and a first supporting wheel 230. The first support 210 is installed on the workbench 100, and the first supporting wheel 230 is rotatably provided on the first support 210. One of the wheel rims 510 of the rim 500 to be processed abuts against the outer peripheral surface of the first supporting wheel 230, which can reduce the contact area between the rim 500 to be processed and the first supporting wheel 230, thereby reducing the friction resistance encountered by the rim 500 to be processed during rotation, so that the rim 500 to be processed can rotate smoothly.

[0049] For example, the first supporting wheel 230 can be rotatably connected to the first support 210 through the first bearing, and the rim 510 of the rim 500 to be processed abuts against the outer peripheral surface of the first supporting wheel 230. When the rim 500 to be processed is rotated, the friction between the rim 500 to be processed and the first supporting wheel 230 is rolling friction, and the friction resistance encountered by the rim 500 to be processed is small, so that the rim 500 to be processed can rotate smoothly. On the one hand, it can reduce the work intensity of the staff, and on the other hand, it can improve the work efficiency when attaching the silent cotton 600.

[0050] Similarly, the second supporting portion includes a second support 220 and a second supporting wheel 240. The second support 220 is installed on the workbench 100, and the second supporting wheel 240 is rotatably provided on the second support 220. One of the wheel rims 510 of the rim 500 to be processed abuts against the outer peripheral surface of the second supporting wheel 240, which can reduce the contact area between the rim 500 to be processed and the second supporting wheel 240, thereby reducing the friction resistance encountered by the rim 500 to be processed during rotation, so that the rim 500 to be processed can rotate smoothly.

[0051] For example, the second supporting wheel 240 can be rotatably connected to the second support 220 through a second bearing, and the rim 510 of the rim 500 to be processed abuts against the outer peripheral surface of the second supporting wheel 240. When the rim 500 to be processed is rotated, the friction between the rim 500 to be processed and the second supporting wheel 240 is rolling friction, and the friction resistance encountered by the rim 500 to be processed is small, so that the rim 500 to be processed can rotate smoothly. On the one hand, it can reduce the work intensity of the staff, and on the other hand, it can improve the work efficiency when attaching the silent cotton 600.

[0052] It should be noted that the first supporting wheel 230 can be fixedly connected to the first support 210, and / or the second supporting wheel 240 can be fixedly connected to the second support 220, which can also facilitate the rotation of the rim 500 to be processed, which will not be described in detail here.

[0053] As another embodiment, the first supporting component 200 can also be a structure in which a first roller and a first bracket are cooperated. The first bracket is installed on the workbench 100. The first roller is a long strip structure. The first roller is rotatably provided on the first bracket. The rim 510 of the rim 500 to be processed abuts against the outer peripheral surface of the first roller, which can also facilitate the rotation of the rim 500. There is no restriction here.

[0054] For example Figure 3 、 Figure 4 As shown, in this embodiment, similarly, the second bearing assembly 300 includes a third bearing part and a fourth bearing part, and the third bearing part and the fourth bearing part are arranged side by side and spaced apart along the axial direction of the rim 500, so that the third bearing part and the fourth bearing part can respectively abut against the corresponding wheel rim 510 of the rim 500. On the one hand, the material cost of the first bearing assembly 200 can be saved to reduce the production and manufacturing cost of the tooling for attaching the rim silent cotton. On the other hand, a second avoidance channel is formed between the third bearing part and the fourth bearing part. The second avoidance channel can avoid the silent cotton 600, so that the silent cotton 600 can pass through the gap between the second bearing assembly 300 and the outer peripheral surface of the rim 500, which can facilitate the attachment of the silent cotton 600 on the outer peripheral surface of the rim 500.

[0055] In this embodiment, the third supporting portion includes a third support 310 and a third supporting wheel 330. The third support 310 is installed on the workbench 100, and the third supporting wheel 330 is rotatably provided on the third support 310. One of the wheel rims 510 of the rim 500 to be processed abuts against the outer peripheral surface of the third supporting wheel 330, which can reduce the contact area between the rim 500 to be processed and the third supporting wheel 330, so as to reduce the friction resistance encountered by the rim 500 to be processed during rotation, so that the rim 500 to be processed can rotate smoothly.

[0056] For example, the third supporting wheel 330 can be rotatably connected to the third support 310 through a third bearing, and the rim 510 of the rim 500 to be processed abuts against the outer peripheral surface of the third supporting wheel 330. When the rim 500 to be processed is rotated, the friction between the rim 500 to be processed and the third supporting wheel 330 is rolling friction, and the friction resistance encountered by the rim 500 to be processed is small, so that the rim 500 to be processed can rotate smoothly. On the one hand, it can reduce the work intensity of the staff, and on the other hand, it can improve the work efficiency when attaching the silent cotton 600.

[0057] Similarly, the fourth supporting portion includes a fourth support 320 and a fourth supporting wheel 340. The fourth support 320 is installed on the workbench 100, and the fourth supporting wheel 340 is rotatably provided on the fourth support 320. One of the wheel rims 510 of the rim 500 to be processed abuts against the outer peripheral surface of the fourth supporting wheel 340, which can reduce the contact area between the rim 500 to be processed and the fourth supporting wheel 340, thereby reducing the friction resistance encountered by the rim 500 to be processed during rotation, so that the rim 500 to be processed can rotate smoothly.

[0058] For example, the fourth supporting wheel 340 can be rotatably connected to the fourth support 320 through the fourth bearing, and the rim 510 of the rim 500 to be processed abuts against the outer peripheral surface of the fourth supporting wheel 340. When the rim 500 to be processed is rotated, the friction between the rim 500 to be processed and the fourth supporting wheel 340 is rolling friction, and the friction resistance encountered by the rim 500 to be processed is small, so that the rim 500 to be processed can rotate smoothly. On the one hand, it can reduce the work intensity of the staff, and on the other hand, it can improve the work efficiency when attaching the silent cotton 600.

[0059] As another embodiment, the second supporting assembly 300 can also be a structure in which a second roller and a second bracket are cooperated. The second bracket is installed on the workbench 100. The second roller is a long strip structure. The second roller is rotatably provided on the second bracket. The rim 510 of the rim 500 to be processed abuts against the outer peripheral surface of the second roller, which can also facilitate the rotation of the rim 500. There is no restriction here.

[0060] For example Figure 4 As shown, in this embodiment, the first supporting wheel 230 is a V-shaped wheel structure, and the first supporting wheel 230 is provided with a first annular groove 231, and the first annular groove 231 is extended around the axial direction of the first supporting wheel 230. The corresponding part of the wheel rim 510 of the rim 500 to be processed is accommodated in the first annular groove 231 and can abut against the side wall of the first annular groove 231, which can limit the movement of the rim 500 to be processed along the axis of the first supporting wheel 230, so as to position the rim 500 to be processed, and improve the attachment quality of the silent cotton 600.

[0061] In this embodiment, along the concave direction of the first annular groove 231, the distance between the opposite side walls of the first annular groove 231 gradually decreases. On the one hand, it can facilitate the rim 510 of the rim 500 to be processed to enter the first annular groove 231, so as to facilitate the installation of the rim 500 to be processed. On the other hand, it can improve the structural strength of the first load-bearing wheel 230, so as to increase the service life of the first load-bearing wheel 230, and further reduce the maintenance cost of the tooling used for attaching the rim silent cotton.

[0062] For example, the opposite side walls of the first annular groove 231 are inclined structures. Along the radial direction of the first load-bearing wheel 230, the cross-section of the first annular groove 231 is a trumpet-shaped structure. Two first support bars are spaced apart on the first load-bearing wheel 230, and a first annular groove 231 is formed between the two first support bars. Along the concave direction of the first annular groove 231, the width of the first support bar along the axial direction of the first load-bearing wheel 230 gradually increases, which can improve the structural strength of the first load-bearing wheel 230, thereby improving the service life of the first load-bearing wheel 230 and reducing the maintenance cost of the tooling used to attach the rim silent cotton.

[0063] As another embodiment, the opposite side walls of the first annular groove 231 may also be a curved surface structure, which is not limited here.

[0064] It should be noted that when the rim 510 of the rim 500 to be processed enters the first annular groove 231, the outer peripheral edge of the rim 510 of the rim 500 abuts against the two first support bars, and part of the gravity applied by the rim 500 on the first load-bearing wheel 230 is transmitted to the first support 210 through one of the first support bars, and the other part of the gravity applied by the rim 500 on the first load-bearing wheel 230 is transmitted to the first support 210 through the other first support 210, which can decompose the gravity applied by the rim 500 on the first load-bearing wheel 230 to avoid excessive concentration of force on the first load-bearing wheel 230 and improve the service life of the first load-bearing wheel 230.

[0065] For example Figure 4 As shown, similarly, in this embodiment, the third load-bearing wheel 330 is a V-shaped wheel structure, and the third load-bearing wheel 330 is provided with a second annular groove 331, and the second annular groove 331 is extended around the axial direction of the third load-bearing wheel 330. The corresponding part of the wheel rim 510 of the rim 500 to be processed is accommodated in the second annular groove 331 and can abut against the side wall of the second annular groove 331, which can limit the movement of the rim 500 to be processed along the axis of the third load-bearing wheel 330, so as to position the rim 500 to be processed, and improve the attachment quality of the silent cotton 600.

[0066] In this embodiment, along the concave direction of the second annular groove 331, the distance between the opposite side walls of the second annular groove 331 gradually decreases. On the one hand, it can facilitate the rim 510 of the rim 500 to be processed to enter the second annular groove 331, so as to facilitate the installation of the rim 500 to be processed. On the other hand, it can improve the structural strength of the third load-bearing wheel 330, so as to increase the service life of the third load-bearing wheel 330, and further reduce the maintenance cost of the tooling used for attaching the rim silent cotton.

[0067] For example, the opposite side walls of the second annular groove 331 are inclined structures. Along the radial direction of the third load-bearing wheel 330, the cross-section of the second annular groove 331 is a trumpet-shaped structure. Two second support bars are spaced apart on the third load-bearing wheel 330, and a second annular groove 331 is formed between the two second support bars. Along the concave direction of the second annular groove 331, the width of the second support bar along the axial direction of the third load-bearing wheel 330 gradually increases, which can improve the structural strength of the third load-bearing wheel 330, thereby improving the service life of the third load-bearing wheel 330 and reducing the maintenance cost of the tooling used to attach the rim silent cotton.

[0068] For example Figure 4 As shown, in this embodiment, a first rib 241 is provided at one end of the second load-bearing wheel 240 away from the first load-bearing wheel 230. The first rib 241 is arranged around the axis of the second load-bearing wheel 240. The first rib 241 can assist in positioning the rim 500 to facilitate installation of the rim 500.

[0069] Similarly, a second rib 341 is provided at one end of the fourth load wheel 340 away from the third load wheel 330 . The second rib 341 is arranged around the axis of the fourth load wheel 340 . The second rib 341 can assist in positioning the rim 500 to facilitate installation of the rim 500 .

[0070] As another embodiment, the opposite side walls of the second annular groove 331 may also be a curved surface structure, which is not limited here.

[0071] Reference Figure 2 、 Figure 4 In this embodiment, the tooling for attaching the rim silent cotton is provided with a first adjustment structure, which is used to adjust the distance between the first bearing part and the second bearing assembly 300 to adapt to rims 500 of different sizes, thereby improving the versatility of the tooling for attaching the rim silent cotton.

[0072] For example, the first adjustment structure includes a first fastening component 250, a first waist-shaped hole 110 provided on the workbench 100, and a first through hole provided on the first bearing part. The first fastening component 250 includes a first bolt and a first nut. The first bolt is passed through the first through hole and the first waist-shaped hole 110. When fixing the first support 210, the nut of the first bolt abuts against the periphery of the first through hole, and the first nut is threadedly engaged with the first bolt and abuts against the periphery of the first waist-shaped hole 110, so that the first bearing part can be fixed. When loosening the first bearing part, it can be done by turning the nut. The operation is simple, convenient and fast, and can easily adjust the distance between the first bearing part and the second bearing component 300 to adapt to rims 500 of different sizes, which can improve the versatility of the tooling used to attach rim silent cotton.

[0073] It should be noted that the first fastening assembly 250 may also include only the first bolt, and the first through hole is configured as a threaded hole structure. The first thread cooperates with the first through hole thread, which can also facilitate fixing or loosening the first support 210, and is not limited here.

[0074] It is understandable that the positions of the first waist-shaped hole 110 and the first through hole can be interchanged, that is, the first waist-shaped hole 110 is provided on the first support 210 and the first through hole is provided on the workbench 100, which is not limited here.

[0075] As another embodiment, the first adjustment structure can also be a structure in which the first motor and the first screw rod are coordinated. The first motor and the first screw rod are both arranged on the workbench 100. The output end of the first motor is connected to the first screw rod. The first screw rod is threadedly engaged with the first support 210. When the first motor drives the first screw rod to rotate, it can drive the first load-bearing wheel 230 to move in the direction of approaching or away from the third load-bearing wheel 330. There is no restriction here.

[0076] In this embodiment, a second adjustment structure is provided between the tooling for attaching the rim silent cotton. The second adjustment structure is used to adjust the distance between the second bearing part and the second bearing assembly 300 to adapt to rims 500 of different sizes, thereby improving the versatility of the tooling for attaching the rim silent cotton.

[0077] For example, the second adjustment structure includes a second fastening component 260, a second waist-shaped hole 120 provided on the workbench 100, and a second through hole provided on the second bearing part. The second fastening component 260 includes a second bolt and a second nut. The second bolt is passed through the second through hole and the second waist-shaped hole 120. When fixing the second bearing part, the nut of the second bolt abuts against the periphery of the second through hole, and the second nut is threadedly engaged with the second bolt and abuts against the periphery of the second waist-shaped hole 120, so that the second bearing part can be fixed. When loosening the second bearing part, it can be done by turning the nut. The operation is simple, convenient and fast, and can easily adjust the distance between the second bearing part and the second bearing component 300 to adapt to rims 500 of different sizes, which can improve the versatility of the tooling used to attach rim silent cotton.

[0078] It should be noted that, in this embodiment, the second through hole is provided on the second support 220 , which will not be described in detail herein.

[0079] It should be noted that the second fastening assembly 260 may also include only a second bolt, and the second through hole is configured as a threaded hole structure. The second thread cooperates with the second through hole thread, which can also facilitate fixing or loosening the second support 220, and is not limited here.

[0080] It is understandable that the positions of the second waist-shaped hole 120 and the second through hole can be interchanged, that is, the second waist-shaped hole 120 is provided on the second support 220, and the second through hole is provided on the workbench 100, which is not limited here.

[0081] As another embodiment, the second adjustment structure can also be a structure in which a second motor and a second screw rod are cooperated. The second motor and the second screw rod are both arranged on the workbench 100. The output end of the second motor is connected to the second screw rod. The second screw rod is threadedly engaged with the second support 220. When the second motor drives the second screw rod to rotate, it can drive the second load-bearing wheel 240 to move in the direction of approaching or away from the third load-bearing wheel 330. There is no restriction here.

[0082] For example Figure 1 、 Figure 2 As shown, in this embodiment, the rolling assembly 400 is located on the side of the first bearing assembly 200 away from the second bearing assembly 300. This ensures that the gap between the rolling assembly 400 and the outer circumference of the rim 500 is not blocked by the first bearing assembly 200. This allows one end of the silent cotton 600 to pass through the gap between the rolling assembly 400 and the outer circumference of the rim 500 from the side of the roller 420, facilitating attachment of the silent cotton 600.

[0083] Reference Figure 5 、 Figure 6 , Figure 5 This is a structural diagram of a rolling assembly according to an embodiment of the present invention. Figure 6This is a front view of a rolling assembly according to an embodiment of the present invention. As shown, in this embodiment, the rolling assembly 400 includes a driving unit 410 and a roller 420. The driving unit 410 is disposed on the workbench 100, and the roller 420 is disposed on the driving unit 410. The driving unit 410 is used to adjust the spacing between the roller 420 and the second supporting assembly 300. The roller 420 is used to roll the silent pad 600 on the outside of the rim 500 to be processed as the rim 500 to be processed rotates, thereby adapting to rims 500 of different sizes and improving the versatility of the tooling used to attach the silent pad to the rim.

[0084] It should be noted that the roller 420 is rotatably provided on the driving part 410, and the roller 420 can rotate relative to the rim 500, reducing the friction between the roller 420 and the silent cotton 600, facilitating the rotation of the rim 500, and the width of the roller 420 can be greater than the width of the silent cotton 600 and smaller than the width of the rim 500 to ensure that the roller 420 can roll the silent cotton 600 at various positions.

[0085] It should be pointed out that the distance between the roller 420 and the outer peripheral surface of the rim 500 to be processed can be 2mm to 3mm, that is, during the processing, the part of the silent cotton 600 that contacts the roller 420 is compressed to 2mm to 3mm. The thickness of the silent cotton 600 under normal conditions is usually about 20mm, so the roller 420 can provide sufficient pressure to roll the silent cotton 600. Other suitable distance ranges between the roller 420 and the outer peripheral surface of the rim 500 to be processed can also be selected according to needs.

[0086] During the actual implementation process, the rim 500 is placed vertically on the first bearing assembly 200 and the second bearing assembly 300. At this time, the axis of the rim 500 is parallel to the axis of the roller 420. One end of the silent cotton 600 is passed from one side of the roller 420 through the gap between the roller 420 and the outer peripheral surface of the rim 500, and the pressure applied by the roller is used to make the end of the silent cotton 600 stick to the outer peripheral surface of the rim 500. After the end is attached, the remaining part of the silent cotton 600 is placed along the outer peripheral surface of the rim 500. The staff rotates the rim 500 in the specified direction. During the rotation of the rim 500, the roller applies pressure to stick the entire silent cotton 600 to the outer peripheral surface of the rim 500.

[0087] It can be understood that, through the arrangement of the driving part 410 and the roller 420, it is convenient to place the silent cotton 600 on the outer peripheral surface of the rim 500 when it is not processed, and it is convenient to install the rim 500 on the first bearing component 200 and the second bearing component 300, thereby avoiding the rim 500 colliding with the roller 420 during installation, resulting in installation failure, and improving the work efficiency of processing the rim 500 and the silent cotton 600.

[0088] For example Figure 5 As shown, in this embodiment, the driving part 410 includes a mounting seat 411 provided on the workbench 100 and a connecting seat 412 connected to the roller 420. The connecting seat 412 is slidably provided on the mounting seat 411 so that the roller 420 can move in a direction close to or away from the second supporting assembly 300 to adapt to rims 500 of different sizes, thereby improving the versatility of the tooling for attaching rim silent cotton.

[0089] During the actual implementation process, when the rim 500 has not been processed, the staff can slide the connecting seat 412 to increase the distance between the roller 420 and the rim 500 to be processed, that is, place the roller 420 at a position farther away from the rim 500 to be processed, so as to facilitate the placement of the silent cotton 600; when the rim 500 is being processed, the staff can operate the connecting seat 412 to shorten the distance between the roller 420 and the rim 500 to be processed. After the roller 420 contacts the silent cotton 600, it continues to apply pressure to the silent cotton 600, so that the thickness of the silent cotton 600 is compressed to a preset value. The staff then rotates the rim 500 so that the roller 420 rolls the silent cotton 600 for at least one week.

[0090] It should be noted that, for example Figure 6 As shown, a guide structure is provided between the mounting seat 411 and the connecting seat 412, and the guide structure includes a slide rail 413 provided on the mounting seat 411 and a slide seat 414 provided on the connecting seat 412. The slide seat 414 is sleeved on the slide rail 413 and slidably cooperates with the slide rail 413 to enable the roller 420 to slide along a preset direction, thereby improving the movement stability of the roller 420.

[0091] As another embodiment, the driving part 410 can also be a structure in which a third motor and a third screw rod are cooperated. The third motor and the third screw rod are both arranged on the workbench 100. The output end of the third motor is connected to the third screw rod. The third screw rod is threadedly cooperated with the third support 310. When the third motor drives the third screw rod to rotate, it can drive the third load-bearing wheel 330 to move in the direction of approaching or moving away from the third load-bearing wheel 330. There is no restriction here.

[0092] In this embodiment, a locking member 430 is provided between the mounting seat 411 and the connecting seat 412. The locking member 430 is a bolt structure. The locking member 430 is passed through the connecting seat 412 and is threadedly engaged with the connecting seat 412. When the connecting seat 412 is locked, one end of the locking member 430 abuts against the mounting seat 411. When the connecting seat 412 is loosened, one end of the locking member 430 is separated from the mounting seat 411. The operation is simple, convenient and fast, and can easily fix or loosen the connecting seat 412 to facilitate adjustment of the distance between the roller 420 and the outer peripheral surface of the rim 500.
