Description

Technical Field

[0001] This utility model relates to the field of wheel hub assembly technology, and in particular to a wheel hub fitting tool. Background Technology

[0002] Figure 2 The sectional view of the cableway wheel liner shown shows that the cableway wheel liner structure includes a hub 1, two retaining rings 2, two sealing rings 3, a rubber wheel 4, and a bearing component 5. The rubber wheel 4 is tightly fitted onto the outer wall of the hub 1, and the rubber wheel 4 exerts an internal clamping force on the hub 1. The two retaining rings 2 are symmetrically arranged on the top and bottom surfaces of the hub 1. The retaining rings 2 have two functions: first, to prevent the base ring 41 from detaching from the hub 1; and second, to support the inner wall of the wing ring 42 and prevent the wing ring 42 from deforming and collapsing. The two sealing rings 3 are symmetrically arranged on the top and bottom surfaces of the hub 1. The function of the sealing rings 3 is to restrict the bearing component 5.

[0003] The problem is that during the assembly of the cableway wheel liner, because the inner diameter of the rubber wheel 4 is slightly smaller than the outer diameter of the hub 1, it is time-consuming and laborious to manually install the rubber wheel 4 onto the outer wall of the hub 1. Since the two retaining rings 2 are symmetrically located on the top and bottom surfaces of the hub 1, the rubber wheel 4 must be located in the exact center of the outer wall of the hub 1. This means that during the installation of the rubber wheel 4, it may be necessary to manually adjust the position of the rubber wheel 4 repeatedly, which is also time-consuming and laborious. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wheel hub fitting fixture that can automatically fit rubber wheels.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed: A hub fitting fixture is used to fit a rubber wheel onto the outer wall of a wheel liner semi-finished product. The wheel liner semi-finished product includes a hub and a retaining ring and a sealing ring connected to its bottom. The fixture includes a conveyor table, a lifting mechanism and a pressing mechanism.

[0006] The conveyor table includes two oppositely arranged conveying sections with a gap between them; the conveyor table is used to convey semi-finished wheel liner products. The lifting mechanism is located below the conveyor tail end of the conveyor platform. From bottom to top, the lifting mechanism includes a first lifting rod, a support plate, and an insert rod. The insert rod is used to insert upward into the through hole at the center of the wheel liner semi-finished product, and the two are matched in size. The support plate is used to lift the wheel liner semi-finished product. The pressing mechanism includes a second lifting rod, a pressure ring, and a guide cylinder. The second lifting rod is mounted directly above the lifting mechanism, and its movable end at the bottom is connected to the pressure ring. From top to bottom, the outer diameter and inner diameter of the guide cylinder gradually increase. The outer diameter at the top of the guide cylinder is smaller than the inner diameter of the rubber wheel, and the inner diameter at the bottom of the guide cylinder is larger than the outer diameter of the hub. The guide cylinder is used to cover the top of the hub. When the pressure ring moves down, it is used to press down the base ring of the rubber wheel, so that the rubber wheel fits onto the outer wall of the hub.

[0007] Furthermore, the top of the insertion rod is designed to be frustoconical.

[0008] Furthermore, the conveying section can be in the form of a conveyor belt or an array of multiple rollers.

[0009] The beneficial effect of this utility model is that it can automatically fit the rubber wheel onto the outer wall of the hub and ensure that the rubber wheel is located in the exact center of the outer wall of the hub. Attached Figure Description

[0010] Figure 1 An exploded view of the cableway wheel liner is shown; Figure 2 A longitudinal sectional view of the cableway wheel liner is shown; Figure 3 The diagram shows the fitting tooling structure. Figure 4 A front view of the conveyor platform and lifting mechanism is shown; Figure 5 The image shows a front view of the lifting mechanism supporting the semi-finished wheel liner. Detailed Implementation

[0011] Example 1 like Figure 1 As shown, this embodiment provides a cableway wheel bushing, including a hub 1, two retaining rings 2, two sealing rings 3, a rubber wheel 4, and a bearing component 5.

[0012] Specifically, such as Figure 1 As shown, the top and bottom surfaces of the hub 1 each have two rings of threaded holes, which are referred to as the outer ring threaded hole and the inner ring threaded hole, respectively, for ease of description. Both the top and bottom surfaces of the hub 1 have annular grooves 12 located between the two rings of threaded holes. The hub 1 has a through hole 11 at its center, extending vertically through the entire hub.

[0013] Specifically, such as Figure 1 , Figure 2 As shown, the rubber wheel 4 includes an integrally formed base ring 41 and two wing rings 42. The base ring 41 is tightly fitted onto the outer wall of the hub 1, and the base ring 41 exerts an internal clamping force on the hub 1. The top surface of the hub 1 is higher than the top surface of the base ring 41, and the bottom surface of the hub 1 is lower than the bottom surface of the base ring 41. The outer wall of the base ring 41 is provided with an arc-shaped groove 411, which is used to support the traction rope of the cableway system. The wing rings 42 are trumpet-shaped, and the two wing rings 42 are symmetrically arranged on the top and bottom surfaces of the base ring 41. Figure 2 As can be seen, the side with the smaller inner diameter of the wing ring 42 is connected to the outer right angle of the base ring 41. The inner wall of the wing ring 42 is set as a first arc surface, and its outer wall is set as a second arc surface. The inner diameter of the second arc surface is larger than that of the arc groove 411.

[0014] Specifically, such as Figure 2As shown, two retaining rings 2 are symmetrically arranged on the top and bottom surfaces of the hub 1. A ring of through holes is arranged on the retaining ring 2, and it is fixedly connected to the threaded holes on the outer ring of the hub 1 by multiple bolts.

[0015] Specifically, such as Figure 2 As shown, two sealing rings 3 are symmetrically arranged on the top and bottom surfaces of the hub 1, and the sealing rings 3 are located within the range of the corresponding retaining rings 2. A ring of through holes is arranged on the sealing rings 3, and they are fixedly connected to the threaded holes of the inner ring of the hub 1 by multiple bolts.

[0016] More specifically, such as Figure 1 , Figure 2 As shown, the bearing component 5 includes two bearings 51, a shaft pin 52, and a sleeve 53. The sleeve 53 is fitted onto the shaft pin 52, and both bearings 51 are fitted onto the sleeve 53. A raised ring 531 is provided on the outer wall of the sleeve 53, and the raised ring 531 is located between the two bearings 51. The inner wall of the sealing ring 3 is tightly attached to the outer wall of the sleeve 53.

[0017] Example 2 like Figure 3 As shown, this embodiment provides a hub fitting fixture for fitting a rubber wheel 4 onto the outer wall of a wheel liner semi-finished product. The wheel liner semi-finished product includes a hub 1 and a retaining ring 2 and a sealing ring 3 connected to its bottom. The fixture includes a conveyor table 105, a lifting mechanism 201 and a pressing mechanism 9.

[0018] Specifically, the conveyor table 105 includes two oppositely arranged conveyor sections, which can be in the form of conveyor belts or multiple roller arrays. There is a gap between the two conveyor sections to avoid the lifting mechanism 201. The conveyor table 105 is used to convey semi-finished wheel liner products.

[0019] Specifically, such as Figure 3 , Figure 4 As shown, the lifting mechanism 201 is located below the conveying end of the conveying platform 105. From bottom to top, the lifting mechanism 201 includes a first lifting rod 202, a support plate 203, and an insert rod 204. The power source of the first lifting rod 202 is a cylinder or a hydraulic cylinder. The top of the insert rod 204 is set in a frustum shape. The insert rod 204 is used to insert upward into the through hole 11 at the center of the wheel liner semi-finished product. The insert rod 204 and the through hole 11 are matched in size. The support plate 203 is used to lift the wheel liner semi-finished product.

[0020] The lifting mechanism 201 is used as follows: the conveyor table 105 sequentially conveys the wheel liner semi-finished products to the top of the lifting mechanism 201. At this time, the wheel liner semi-finished products at the end of the conveyor table 105 are not directly above the insertion rod 204. The two may be offset by several millimeters in the four directions of front, back, left, and right. The insertion rod 204 is inserted upward into the through hole 11 at the center of the wheel liner semi-finished product so that the wheel liner semi-finished product and the insertion rod 204 are on the same axis. Then the support plate 203 continues to lift the wheel liner semi-finished product upward, so that there is a certain gap between the bottom surface of the wheel liner semi-finished product and the conveying part of the conveyor table 105. This gap is for the convenience of fitting the rubber wheel 4.

[0021] Specifically, such as Figure 1 , Figure 3 , Figure 5 As shown, the pressing mechanism 9 includes a second lifting rod 91, a pressure ring 93, and a guide cylinder 92. The second lifting rod 91 is mounted directly above the lifting mechanism 201, and its bottom movable end is connected to the pressure ring 93. From top to bottom, the outer diameter and inner diameter of the guide cylinder 92 gradually increase. The outer diameter of the top end of the guide cylinder 92 is smaller than the inner diameter of the rubber wheel 4, and the inner diameter of the bottom end of the guide cylinder 92 is slightly larger than the outer diameter of the hub 1. The guide cylinder 92 is used to cover the top of the hub 1. When the pressure ring 93 moves down, it is used to press down the base ring 41 of the rubber wheel 4, so that the rubber wheel 4 is fitted onto the outer wall of the hub 1.

[0022] How to use the pressing mechanism 9: After the lifting mechanism 201 lifts the semi-finished wheel bushing, a rubber wheel 4 is put onto the guide cylinder 92 manually or by a robotic arm; the second lifting rod 91 moves the pressure ring 93 down, and the pressure ring 93 presses down on the base ring 41 of the rubber wheel 4, so that the rubber wheel 4 is put onto the outer wall of the hub 1 until the bottom of the rubber wheel 4 contacts the retaining ring 2, and the pressure ring 93 stops moving down, thus ensuring that the rubber wheel 4 is put onto the center of the hub 1; the guide cylinder 92 is removed manually or by a robotic arm; the pallet 203 and the insertion rod 204 are reset downwards, and the conveyor table 105 continues to convey.

[0023] It should be noted that the fitting tool provided in this embodiment is used to fit the rubber wheel 4 onto the outer wall of the hub 1 in the wheel bushing semi-finished product, rather than fitting the rubber wheel 4 onto the outer wall of the hub 1 alone. The reason is that during the fitting process, the pressure ring 93 stops moving downwards until the bottom of the rubber wheel 4 contacts the retaining ring 2. Therefore, the retaining ring 2 in the wheel bushing semi-finished product can be used to define the position of the rubber wheel 4 and prevent the rubber wheel 4 from moving downwards excessively. Imagine if the rubber wheel 4 were fitted onto the outer wall of the hub 1 alone; without the restraint of the retaining ring 2 during the fitting process, the rubber wheel 4 might move downwards excessively.

[0024] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
