Description

Technical Field

[0001] This invention relates to the field of assembly technology, and in particular to a cableway wheel liner assembly device and method. Background Technology

[0002] In cableway systems, metal wheel bushings are prone to wear on the traction rope, and prolonged use may lead to rope breakage, severely impacting the cableway's operational safety. To improve equipment durability and operational safety, the applicant's researchers have designed a new type of cableway wheel bushing, such as... Figures 1-3 As shown, the wheel includes a hub 1, two retaining rings 2, two sealing rings 3, a rubber wheel 4, and a bearing 5. The top and bottom surfaces of the hub 1 are each arranged with two rings of threaded holes. A through hole 11 is provided at the center of the hub 1. 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. The two retaining rings 2 are symmetrically arranged on the top and bottom surfaces of the hub 1 and are fixedly connected to the threaded holes of the outer ring of the hub 1 by multiple bolts. The two sealing rings 3 are symmetrically arranged on the top and bottom surfaces of the hub 1 and are fixedly connected to the threaded holes of the inner ring of the hub 1 by multiple bolts. The function of the sealing rings 3 is to confine the bearing 5 within the through hole 11.

[0003] The following problems exist when assembling the aforementioned cableway wheel bushings:

[0004] ① In order to make the rubber wheel 4 fit tightly on the hub 1, the inner diameter of the rubber wheel 4 in its natural state needs to be slightly smaller than the outer diameter of the hub 1. This would make the process of manually fitting the rubber wheel 4 onto the outer wall of the hub 1 very time-consuming and laborious.

[0005] ②The number of bolts is very large, and the process of manually installing the bolts is time-consuming and labor-intensive;

[0006] ③ The entire assembly process relies too heavily on manual labor, resulting in low efficiency, which needs improvement. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a cableway wheel liner assembly device and method. First, it solves the problem of manual bolt installation by automatically aligning the wheel hub, retaining ring, and sealing ring, and automatically installing the bolts. Second, it solves the problem of manual rubber wheel fitting by automatically fitting the rubber wheel onto the wheel hub.

[0008] In order to achieve the objective of this invention, the following solution is proposed:

[0009] A cableway wheel liner assembly device, the cableway wheel liner includes a hub, two retaining rings, two sealing rings, a rubber wheel, and bearing components. The device includes multiple conveyor platforms, a centering mechanism, a steering mechanism, bolt installation equipment, and a clamping mechanism.

[0010] The first, second, and third conveyor platforms are arranged side by side and are all located on one side of the clamping mechanism. They are used to convey the retaining ring, the hub, and the sealing ring toward the clamping mechanism, respectively. Each conveyor platform includes two oppositely arranged conveying sections with a gap between them.

[0011] The centering mechanism is located below the conveyor tail end and is used to insert three cones of different sizes upwards into the center of the retaining ring, hub and sealing ring respectively to achieve centering;

[0012] The directional adjustment mechanism includes a stroke mechanism, a first lifting rod, a first motor, and a clamping component. The clamping component includes a first control box, two sleeves, and two clamping rods. The stroke mechanism is mounted or suspended above the conveyor table and is connected to the first lifting rod. The movable end of the bottom of the first lifting rod is connected to the first motor. The bottom output shaft of the first motor is connected to the first control box. The bottom of the first control box is connected to two sleeves for adjusting the distance between the two sleeves. The top of the clamping rod is slidably disposed inside the sleeve. The sleeve is equipped with a spring that exerts a downward force on the clamping rod and a spring sensor. The stroke mechanism is used to move the clamping component above the centering retaining ring / hub / sealing ring. The two clamping rods are used to insert into the two holes of the retaining ring / hub / sealing ring for directional adjustment and clamping.

[0013] The clamping mechanism is used to clamp the wheel hub after centering and reversing.

[0014] Bolt installation equipment is located outside or above the conveyor table and is used to connect the retaining ring and sealing ring to the top of the hub to obtain a primary semi-finished product.

[0015] Furthermore, both side walls at the tail end of the second conveyor are provided with notches. The clamping mechanism includes a second control box and two clamping plates. The two ends of the second control box are respectively located on the two support plates, and the clamping plates are located at the corresponding notches. The second control box connects the two clamping plates and is used to adjust the distance between the two clamping plates.

[0016] Furthermore, the clamping mechanism also includes a second motor, which is located on the outer wall of one of the support plates. Its output shaft passes through the support plate and is connected to one end of the second control box. The other end of the second control box is rotatably connected to another support plate. The fourth, fifth, and sixth conveyor platforms are arranged side by side and are all located on the other side of the clamping mechanism. The fourth and sixth conveyor platforms are used to convey rubber wheels and bearing parts towards the clamping mechanism, respectively. Under the action of the second motor, the clamping plate is used to flip the primary semi-finished product onto the fifth conveyor platform.

[0017] Furthermore, the device also includes a lifting mechanism located below the fifth conveyor platform. From bottom to top, the lifting mechanism includes a third 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 primary semi-finished product, and the two are matched in size. The support plate is used to lift the primary semi-finished product.

[0018] Furthermore, the device also includes a robotic arm and a fitting fixture. The robotic arm is located outside the conveyor table. The fitting fixture includes a second lifting rod, a pressure ring, and a guide cylinder. The second lifting rod is mounted or suspended directly above the lifting mechanism. 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. After the lifting mechanism lifts the primary semi-finished product, the robotic arm is used to place a bearing component in the through hole at the center of the primary semi-finished product, to cover the top of the primary semi-finished product with the guide cylinder, and to fit a rubber wheel onto the guide cylinder. 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.

[0019] Furthermore, each clamping plate has two arc-shaped clamping grooves on its inner wall, one of which is located outside the other. The outer clamping groove is used to clamp and fix the hub at the tail end of the second conveyor. When the clamping plate flips the primary semi-finished product onto the fifth conveyor, all the clamping grooves are within the range of the fifth conveyor in the downward projection of the clamping plate. The stroke mechanism is also used to move the clamping part above the fifth conveyor.

[0020] Furthermore, both conveying sections of the sixth conveyor table use annular conveyor belts, and multiple limiting plates are arrayed along the annular track of the conveyor belt. The inner end of the limiting plate is provided with an arc-shaped limiting groove, and the limiting plates at two corresponding positions are used to clamp the shaft pins of the bearing components.

[0021] A method for assembling cableway wheel bushings, using the aforementioned apparatus, includes the following steps:

[0022] S1. The first conveyor table, the second conveyor table, and the third conveyor table respectively convey the retaining ring, the wheel hub, and the sealing ring towards the clamping mechanism;

[0023] S2. The centering mechanism inserts three cones of different sizes upwards into the center of the retaining ring, hub and sealing ring respectively to achieve centering;

[0024] S3. The clamping parts move to the centering hub. Under the action of the first lifting rod and the first motor, the two clamping rods are inserted into the two holes of the hub, and then the hub is adjusted to the preset orientation.

[0025] S4. The clamping mechanism clamps the wheel hub after centering and adjustment.

[0026] S5. The clamping device moves to the centering retaining ring, adjusts the direction of the retaining ring, and then transfers it to the corresponding wheel hub. The bolting device connects the retaining ring to the wheel hub.

[0027] S6. The clamping component moves to the centering sealing ring, adjusts the sealing ring's orientation, and then transfers it to the corresponding wheel hub. The bolt installation device connects the sealing ring to the wheel hub, resulting in a primary semi-finished product.

[0028] The beneficial effects of this invention are as follows: through the ingenious cooperation of multiple conveying platforms, centering mechanism, direction adjustment mechanism, bolt installation equipment and clamping mechanism, the hub, retaining ring and sealing ring can be automatically aligned and the bolts can be automatically installed, solving the problem of manual bolt installation; through the cooperation of robotic arm and fitting tooling, the rubber wheel can be automatically fitted onto the hub, solving the problem of manual rubber wheel fitting.

[0040] Example 1

[0041] 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.

[0042] Specifically, such as Figure 2 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.

[0043] Specifically, such as Figure 2 , Figure 3 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 3 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.

[0044] Specifically, such as Figure 3 As 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 fixed to the threaded holes on the outer ring of the hub 1 by multiple bolts. Taking the retaining ring 2 located on the top surface of the hub 1 as an example, the bottom surface of the retaining ring 2 is in close contact with both the top surface of the hub 1 and the top surface of the base ring 41. The outer wall of the retaining ring 2 is set as a third arc surface, which is in close contact with the first arc surface of the wing ring 42. The retaining ring 2 has 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.

[0045] from Figure 3 As can be seen from this, the outer distance between the two retaining rings 2 is less than the thickness of the rubber wheel 4. The outer distance between the two retaining rings 2 refers to the maximum length of the distance between the two retaining rings 2, and the thickness of the rubber wheel 4 refers to the outer distance between the two wing rings 42.

[0046] When the cableway system is running, the retaining ring 2 provides sufficient support to the rubber wheel 4, preventing the cableway's traction rope from detaching from the rubber wheel 4. Normally, the traction rope is located within the arc-shaped groove 411. When the wind is too strong, causing the traction rope to swing excessively, it may extend beyond the arc-shaped groove 411 and move into the range of the wing ring 42. Therefore, the function of the wing ring 42 is to accommodate the traction rope and limit its swing amplitude, thus improving safety. When the wind is weak, the traction rope can automatically return to the arc-shaped groove 411, and the wing ring 42 will not obstruct its return.

[0047] Specifically, such as Figure 3 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 ring 3, and it is fixedly connected to the threaded hole of the inner ring of the hub 1 by multiple bolts. The function of the sealing ring 3 is to restrict the bearing component 5 within the through hole 11.

[0048] More specifically, such as Figure 2 , Figure 3 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. 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. Taking the sealing ring 3 located on the top surface of the hub 1 as an example, the bottom surface of the sealing ring 3 is simultaneously tightly attached to the top surface of the hub 1 and the top surface of the corresponding bearing 51. The top surface of the sealing ring 3 is flush with the top surface of the sleeve 53.

[0049] In summary, this solution utilizes the contact between the rubber wheel 4 and the traction rope to achieve its function. The buffering and protective properties of the rubber wheel 4 reduce wear on the traction rope, ensuring the safe and stable operation of the cableway. When the rubber wheel 4 wears out, the bolts on the retaining ring 2 are loosened, the rubber wheel 4 is removed, and a new rubber wheel 4 is installed; the wheel liner can then be reused repeatedly.

[0050] Example 2

[0051] like Figure 4 As shown, this embodiment provides a cableway wheel liner assembly device for assembling the cableway wheel liner of Embodiment 1. The device includes three conveyor platforms, a centering mechanism 7, a steering mechanism 8, a bolt installation device, and a clamping mechanism 6.

[0052] Specifically, such as Figure 4 As shown, the three conveying platforms are the first conveying platform 101, the second conveying platform 102 and the third conveying platform 103. These three conveying platforms are arranged side by side and are all located on one side of the clamping mechanism 6. The first conveying platform 101, the second conveying platform 102 and the third conveying platform 103 are used to convey the retaining ring 2, the hub 1 and the sealing ring 3 towards the clamping mechanism 6, respectively.

[0053] Specifically, such as Figure 4 As shown, each conveyor table includes two oppositely arranged conveyor sections with a gap between them. This gap is designed to avoid the cone 71 of the centering mechanism 7. The specific structure of the conveyor section can be implemented using a conveyor belt or a roller conveyor; both are existing technologies and will not be described in detail here.

[0054] Specifically, such as Figure 4 , Figure 7As shown, the centering mechanism 7 is located below the conveying tail ends of the three conveyor platforms. It includes a fourth lifting rod 74, a horizontal plate 73, three columns 72, and three truncated cones 71 of different sizes. The fourth lifting rod 74 is driven by a cylinder or hydraulic cylinder, and its movable end is connected to the horizontal plate 73. The three columns 72 are all located on top of the horizontal plate 73, and the three truncated cones 71 are respectively located on top of their corresponding columns 72. At the conveying tail ends of the three conveyor platforms, the centering mechanism 7 is used to insert the three truncated cones 71 of different sizes upwards into the centers of the retaining ring 2, hub 1, and sealing ring 3, respectively, to achieve centering. Centering means that the retaining ring 2, hub 1, and sealing ring 3 are coaxial with their corresponding truncated cones 71.

[0055] Instructions for using Agency 7 (or similar agency):

[0056] The first conveyor 101, the second conveyor 102, and the third conveyor 103 respectively convey the retaining ring 2, the hub 1, and the sealing ring 3 towards the clamping mechanism 6. When the retaining ring 2, the hub 1, and the sealing ring 3 are conveyed to the end of the conveying process, the corresponding conveyor stops running. It is worth noting that at this time, the positions of the retaining ring 2, the hub 1, and the sealing ring 3 are not precise and may deviate by several centimeters in the four directions of front, back, left, and right.

[0057] Then, the fourth lifting rod 74 moves the horizontal plate 73 upward, causing the three cones 71 of different sizes to be inserted upward into the center of the retaining ring 2, the hub 1 and the sealing ring 3 respectively. The horizontal plate 73 stops when it moves to the preset height. At this time, the retaining ring 2, the hub 1 and the sealing ring 3 are all aligned and coaxial with their respective cones 71.

[0058] Specifically, such as Figure 4 , Figure 6 As shown, the steering mechanism 8 includes a stroke mechanism 81, a first lifting rod 82, a first motor 86, and clamping components. The clamping components include a first control box 83, two sleeves 84, and two clamping rods 85. The stroke mechanism 81 is mounted or suspended above the three conveyor platforms and is connected to the first lifting rod 82. The movable end of the bottom of the first lifting rod 82 is connected to the first motor 86. The power source for the first lifting rod 82 is a pneumatic or hydraulic cylinder. The bottom output shaft of the first motor 86 is connected to the first control box 83, and the bottom of the first control box 83 is connected to the two sleeves 84. The tube 84 is used to adjust the distance between the two sleeves 84. The top of the clamping rod 85 is slidably disposed inside the sleeve 84. The sleeve 84 is provided with a spring that generates a downward force on the clamping rod 85 and a spring sensor. The spring sensor is used to detect the state of the spring. The state of the spring determines whether the first motor 86 runs. The stroke mechanism 81 is used to move the clamping member above the centering retaining ring 2 / hub 1 / sealing ring 3. The two clamping rods 85 are used to insert into the two holes of the retaining ring 2 / hub 1 / sealing ring 3, and then adjust and clamp. The specific principle is described below.

[0059] In the above scheme, the stroke mechanism 81, the first control box 83, and the spring sensor are all existing technologies, and their structures and principles will not be described in detail.

[0060] Specifically, the clamping mechanism 6 is used to clamp the wheel hub 1 after centering and reversing. In this embodiment, the clamping mechanism 6 is implemented as follows: Figure 4 , Figure 5 As shown, both side walls of the conveying tail end of the second conveyor table 102 are provided with notches 1021. The clamping mechanism 6 includes a second control box 61 and two clamping plates 62. The two ends of the second control box 61 are respectively located on two support plates 63. The clamping plates 62 are located at the corresponding notches 1021. The second control box 61 connects the two clamping plates 62 and is used to adjust the distance between the two clamping plates 62. The second control box 61 is prior art, and its structure and principle will not be described in detail.

[0061] Specifically, the bolt installation device is located outside or above the conveyor table and is used to connect the centering retaining ring 2 and sealing ring 3 to the top of the centering hub 1. The bolt installation device is existing technology, so its structure is not shown in the attached drawings, and its structure and principle will not be described in detail here.

[0062] Instructions for using the steering mechanism 8:

[0063] After the retaining ring 2, hub 1, and sealing ring 3 are aligned, the horizontal plate 73 continues to rise. Under the action of the stroke mechanism 81, the first lifting rod 82, the first motor 86, and the clamping component are moved as a whole. The clamping component first moves to above the aligned hub 1. The first control box 83 adjusts the distance between the two sleeves 84, which is consistent with the distance between the two symmetrical holes on the hub 1. The first lifting rod 82 causes the clamping component to move down. It should be noted that in rare cases, the two clamping rods 85 may directly insert downwards into the two holes of the hub 1. In this case, the first motor 86 does not need to work anymore because the hub 1 is in the preset orientation at this time. However, in most cases, the two clamping rods 85 move downwards. The clamping rod 85 will first contact the top surface of the hub 1, and then the clamping rod 85 will retract into the sleeve 84 due to resistance. The first lifting rod 82 will stop, and the spring sensor will detect that the spring in the sleeve 84 is in a compressed state. Then the first motor 86 will start to rotate the clamping member counterclockwise. When the two clamping rods 85 rotate to the positions of the two holes, the clamping rods 85 will be inserted downward into the corresponding holes under the action of the spring. The spring sensor will detect that the spring in the sleeve 84 has returned to its original state, and then the first motor 86 will start to rotate the clamping member clockwise. At this time, the angle of clockwise rotation is equal to the angle of counterclockwise rotation in the previous step. After the hub 1 is aligned and adjusted, the two clamping plates 62 clamp the hub 1, and then the clamping rod 85 will disengage from the hub 1.

[0064] Under the action of the stroke mechanism 81, the first lifting rod 82, the first motor 86, and the clamping component are moved as a whole. The clamping component moves to above the centered retaining ring 2, and the retaining ring 2 is adjusted according to the same adjustment steps as above. The difference is that after the retaining ring 2 is adjusted, the two clamping rods 85 should not be disengaged from the retaining ring 2. The first control box 83 continues to adjust the distance between the two sleeves 84, so that the two clamping rods 85 clamp the retaining ring 2. Under the action of the stroke mechanism 81 and the first lifting rod 82, the clamping component and the retaining ring 2 are moved to above the wheel hub 1, and the retaining ring 2 is placed on the top of the wheel hub 1. Because the wheel hub 1 and the retaining ring 2 have been centered and adjusted, the holes of the wheel hub 1 and the retaining ring 2 are now in a one-to-one correspondence. The bolt installation equipment automatically installs the bolts and connects the retaining ring 2 to the top of the wheel hub 1. During this process, two symmetrically positioned bolts can be installed first, and then the clamping rod 85 can be disengaged from the retaining ring 2, so as not to hinder the installation of the remaining bolts.

[0065] Similarly, the sealing ring 3 is oriented according to the above-mentioned directional adjustment steps, and the sealing ring 3 is connected to the top of the wheel hub 1 according to the above-mentioned bolt installation steps to obtain the primary semi-finished product.

[0066] The above solution solves the problem of manual bolt installation, and can automatically align the hub 1, retaining ring 2, and sealing ring 3, and automatically install the bolts. Furthermore, this embodiment adopts the following solution to solve the problem of manually fitting the rubber wheel 4:

[0067] More specifically, such as Figure 8 As shown, the assembly device is further equipped with three additional conveyor platforms: a fourth conveyor platform 104, a fifth conveyor platform 105, and a sixth conveyor platform 106. The clamping mechanism 6 also includes a second motor 64, which is located on the outer wall of one of the support plates 63. The output shaft of the second motor 64 passes through the support plate 63 and is connected to one end of a second control box 61. The other end of the second control box 61 is rotatably connected to another support plate 63. The fourth conveyor platform 104, the fifth conveyor platform 105, and the sixth conveyor platform 106 are arranged side by side and are all located on the other side of the clamping mechanism 6. The fourth conveyor platform 104 and the sixth conveyor platform 106 are used to convey the rubber wheel 4 and the bearing component 5 towards the clamping mechanism 6, respectively. It should be noted that the bearing component 5 has been pre-assembled, and this embodiment does not involve the assembly of the bearing component 5 itself.

[0068] Because the structure of bearing component 5 differs significantly from other parts, special modifications are necessary to the structure of the sixth conveyor table 106 in order to maintain bearing component 5 in a certain state during transport. For example... Figure 8As shown, both conveying sections of the sixth conveyor table 106 use annular conveyor belts. Multiple limiting plates 1061 are arrayed along the conveyor belt's annular trajectory. The inner end of each limiting plate 1061 has an arc-shaped limiting groove 1062. Two corresponding limiting plates 1061 are used to clamp the shaft pin 52 of the bearing component 5. More precisely, the shaft pin 52 includes a cap, a rod, and a nut. The diameter of the cap or nut is larger than the diameter of its rod. Therefore, the two limiting plates 1061 actually clamp the rod of the shaft pin 52, further preventing the bearing component 5 from falling downwards. When the two conveying sections of the sixth conveyor table 106 run in opposite directions, the two limiting plates 1061 gradually separate at the ends of the conveying sections, thus releasing the clamping restriction on the bearing component 5.

[0069] Under the action of the second motor 64, the clamping plate 62 is used to flip the primary semi-finished product onto the fifth conveyor table 105. After the primary semi-finished product is flipped, the other side without the retaining ring 2 and sealing ring 3 is exposed, which facilitates the subsequent installation of the rubber wheel 4 and also makes it convenient to install the remaining retaining ring 2 and sealing ring 3. It should be noted here that before the clamping plate 62 flips, under the action of the stroke mechanism 81, the first lifting rod 82, the first motor 86 and the clamping parts need to be moved away from the primary semi-finished product as a whole to prevent obstruction of the flipping trajectory of the clamping plate 62 and the primary semi-finished product.

[0070] Because clamping plate 62 holds the primary semi-finished product, or more precisely, clamping plate 62 holds the outer wall of the wheel hub 1 within the primary semi-finished product, the design concept for fitting the rubber wheel 4 is as follows: First, ensure that the central axis of the primary semi-finished product cannot move. Then, release the clamping and fixing of clamping plate 62, and then lift the primary semi-finished product upwards. The specific implementation method is as follows:

[0071] like Figure 9 As shown, the assembly device also includes a lifting mechanism 201 located below the fifth conveyor table 105. From bottom to top, the lifting mechanism 201 includes a third lifting rod 202, a support plate 203, and an insertion rod 204. The third lifting rod 202 is driven by a cylinder or a hydraulic cylinder. The insertion rod 204 is used to insert upward into the through hole 11 at the center of the primary semi-finished product, and the size of the insertion rod 204 matches that of the through hole 11. The diameter of the support plate 203 is larger than that of the insertion rod 204, and the support plate 203 is used to lift the primary semi-finished product upward.

[0072] The lifting mechanism 201 is used as follows: under the action of the second motor 64, the clamping plate 62 flips the primary semi-finished product onto the fifth conveyor table 105; the insert rod 204 is inserted upward into the through hole 11 at the center of the primary semi-finished product, and then the clamping plate 62 releases the primary semi-finished product, and the support plate 203 continues to lift the primary semi-finished product upward, so that a certain gap is left between the bottom surface of the primary semi-finished product and the conveying part of the fifth conveyor table 105. This gap is for the convenience of installing the rubber wheel 4.

[0073] More specifically, such as Figure 9 , Figure 10 As shown, the device also includes a robotic arm and a fitting fixture 9. The robotic arm is located outside the conveyor table. Since the robotic arm is existing technology, its structure is not specifically shown in the attached drawings and will not be described in detail here. The fitting fixture 9 includes a second lifting rod 91, a pressure ring 93, and a guide cylinder 92. The second lifting rod 91 is mounted or suspended directly above the lifting mechanism 201. The power source for the second lifting rod 91 is a cylinder or hydraulic cylinder. The movable end at the bottom of the second lifting rod 91 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 at the top of the guide cylinder 92 is smaller than the inner diameter of the rubber wheel 4, and the inner diameter at the bottom of the guide cylinder 92 is slightly larger than the outer diameter of the hub 1.

[0074] How to use the robotic arm and fitting fixture 9: After the lifting mechanism 201 lifts the primary semi-finished product, the two conveying sections of the sixth conveyor table 106 move in opposite directions. The robotic arm clamps a bearing component 5 located at the end of the conveying section. As the two limiting plates 1061 gradually separate, the clamping restriction on the bearing component 5 is released. The robotic arm then places the bearing component 5 into the through hole 11 at the center of the primary semi-finished product. Then, the robotic arm covers the top of the primary semi-finished product with the guide cylinder 92 (in the state as shown). Figure 10 (As shown); the robotic arm then clamps a rubber wheel 4 and places the rubber wheel 4 onto the guide cylinder 92; 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 placed on the outer wall of the hub 1, thus obtaining the secondary semi-finished product; the robotic arm removes the guide cylinder 92; the pallet 203 and the insertion rod 204 are reset downwards, and the secondary semi-finished product falls onto the fifth conveyor table 105.

[0075] Because the tooling 9 is positioned directly above the secondary semi-finished product, the adjusting mechanism 8 cannot be used to move the remaining retaining rings 2 and sealing rings 3. Therefore, this embodiment makes the following improvements: Figure 5 As shown, each clamping plate 62 has two arc-shaped clamping grooves 621 on its inner wall. One clamping groove 621 is located outside the other clamping groove 621. "Outer" refers to its position being further away from the second control box 61. The outer clamping groove 621 is used to clamp the hub 1 at the tail end of the second conveyor table 102. When the clamping plate 62 flips the primary semi-finished product onto the fifth conveyor table 105, as... Figure 8 , Figure 9 , Figure 11 As shown, the outer clamping groove 621 is located below the fitting tool 9, while the inner clamping groove 621 is located below the stroke mechanism 81, and the inner clamping groove 621 is still within the range of the fifth conveyor table 105.

[0076] The method of use is as follows: As mentioned above, the pallet 203 and the insert rod 204 are reset downwards, and the secondary semi-finished product falls onto the fifth conveyor table 105; the fifth conveyor table 105 conveys the secondary semi-finished product towards the second control box 61, conveying the secondary semi-finished product to the clamping groove 621 on the inner side of the clamping plate 62. Then the distance between the two clamping plates 62 is reduced until the clamping groove 621 is close to the outer wall of the rubber wheel 4. Note that it is only close, not clamped tightly. The purpose of this operation is to center the secondary semi-finished product, so as to facilitate the subsequent adjustment of the secondary semi-finished product using the adjustment mechanism 8; the clamping part moves above the secondary semi-finished product, and after the secondary semi-finished product is adjusted, the clamping plate 62 clamps the secondary semi-finished product, as shown in the figure. Figure 11 As shown; the first conveyor 101, the second conveyor 102, and the third conveyor 103 respectively convey the retaining ring 2, the hub 1, and the sealing ring 3 towards the clamping mechanism 6; the centering mechanism 7 inserts three cones 71 of different sizes upwards into the center of the retaining ring 2, the hub 1, and the sealing ring 3 respectively to achieve centering; the clamping component then moves to above the centered retaining ring 2, adjusts the direction of the retaining ring 2, and then transfers it to the secondary semi-finished product, and the bolt installation device connects the retaining ring 2 to the hub 1; following the same operation, the sealing ring 3 is then connected to the hub 1 to obtain the assembled cableway wheel liner; the clamping plate 62 loosens the cableway wheel liner, and the fifth conveyor 105 conveys the cableway wheel liner away from the second control box 61, preferably conveying the cableway wheel liner to another new conveyor.
