[0037] With the development of economy and the progress of science and technology, air wheels have become an indispensable part of people's production and life, such as vehicles such as cars, bicycles, electric vehicles, and chairs, supports and the like with air wheels. In some processing scenarios, it is necessary to assemble the tire and the hub of the air wheel. In the related art, the tire has elasticity, and the inner ring size of the tire is larger than the outer ring size of the hub. The inner ring edge of the tire is pressed into the hub by manual pressing to complete the assembly of the air wheel. Manual work is time-consuming, high in cost, and does not have high assembly efficiency, and the assembly is difficult.

[0038] As shown in Figures 1-3 The present application embodiment provides an imitation pneumatic wheel assembly jig 10 suitable for adjusting the imitation pneumatic tire preassembled to the hub to the assembly position. The imitation pneumatic wheel assembly jig 10 comprises a rack 100 and a positioning turntable 200 and an assembly mechanism 300 arranged on the rack 100.

[0039] As shown in Figure 1 In order to facilitate the movement of the imitation pneumatic wheel assembly jig 10, the rack 100 can be arranged as a movable structure, for example, the bottom of the rack 100 can be provided with a universal wheel 101 with a brake, so as to facilitate the movement and fixing position of the rack 100.

[0040] As shown in Figures 1-3As shown, the positioning turntable 200 has a limiting clamp 210 for limiting the wheel hub, and the wheel hub limited by the limiting clamp 210 is in a state that the wheel shaft S is vertical, and the upper and lower sides of the imitation pneumatic tire pre-assembled to the wheel hub are exposed from the limiting clamp 210; the positioning turntable 200 drives the limiting clamp 210 and the wheel hub and the imitation pneumatic tire clamped by the limiting clamp 210 to rotate around the wheel shaft S of the wheel hub. The positioning turntable 200 has a bearing surface 201 for bearing the wheel and a wheel shaft perpendicular to the bearing surface 201, and the wheel shaft S of the wheel hub is collinear with the wheel shaft, that is, the positioning turntable 200 drives the limiting clamp 210 and the wheel hub and the imitation pneumatic tire clamped by the limiting clamp 210 to rotate around the wheel shaft S. It can be understood that, considering the shape of the general wheel hub and the imitation pneumatic tire, the positioning turntable 200 can adopt a cylindrical body, and the bearing surface 201 can be a circular end face.

[0041] Further, as shown in Figure 2 、 Figure 3 , the wheel hub can be close to the bearing surface 201, and in some embodiments, a plurality of positioning holes are arranged on the wheel hub, as shown in Figure 3 , three positioning holes can be arranged on the wheel hub, and the limiting clamp 210 includes three positioning blocks 211 corresponding to the three positioning holes, when the positioning turntable 200 bears the wheel hub and the imitation pneumatic tire, the limiting clamp 210 can be located in the corresponding positioning hole to accurately position the position of the wheel hub and the imitation pneumatic tire on the positioning turntable 200. It can be understood that, on the one hand, the position of the limiting clamp 210 can correspond to the position of the positioning hole, so that when the wheel hub and the imitation pneumatic tire are placed on the positioning turntable 200, the wheel hub and the imitation pneumatic tire can be positioned by the limiting clamp 210, on the other hand, the shape of the positioning block 211 can also correspond to the shape of the positioning hole, for example, the shape of each positioning hole is circular, and the positioning block 211 can be arranged in a corresponding circular structure; the shape of the positioning hole is diamond-shaped, and the limiting clamp 210 can be arranged in a corresponding diamond-shaped structure. Further, the number of positioning blocks 212 can also be the same as the number of positioning holes, for example, when the number of positioning holes is two, the number of positioning blocks 211 is also two; on the other hand, the number of positioning blocks 211 can also be different from the number of positioning holes, for example, when the number of positioning holes is three, the number of positioning blocks 211 can be two, that is, the limiting clamp 210 can be arranged according to the positioning hole of the wheel hub and the imitation pneumatic tire, and can be adjusted according to the actual situation.

[0042] As shown in Figures 1-3As shown, the assembling mechanism 300 includes two assembling tool bits 310 arranged on the upper and lower sides of the limiting clamp 210 respectively, and a driving member 320 driving the two assembling tool bits 310 to move towards or away from each other, the two assembling tool bits 310 are opposite to the joint of the imitation pneumatic tire and the hub in the vertical direction F1, and the two assembling tool bits 310 are driven by the driving member 320 to move towards the joint of the imitation pneumatic tire and the hub, and to push the imitation pneumatic tire to the assembly position of the hub with the rotation of the hub. The assembling mechanism 300 is arranged on the rack 100, and the two assembling tool bits 310 can be distributed on the upper and lower sides of the limiting clamp 210 in the vertical direction F1. The driving member 320 can drive the two assembling tool bits 310 to move towards or away from each other, and the two assembling tool bits 310 are driven by the driving member 320 to move in the direction of approaching each other, so that the two assembling tool bits 310 are inserted into the joint of the imitation pneumatic tire and the hub from the upper and lower directions respectively; when the positioning turntable 200 drives the limiting clamp 210, the hub and the imitation pneumatic tire clamped by the limiting clamp 210 to rotate around the hub shaft, the imitation pneumatic tire is pushed to the assembly position of the hub with the rotation of the hub, and the positioning turntable 200 drives the hub to rotate one circle to realize the assembly of the hub and the imitation pneumatic tire.

[0043] It can be understood that, in order to facilitate the control of the two assembling tool bits 310, the number of the driving members 320 can be the same as the number of the assembling tool bits 310, that is, two driving members 320 respectively drive two assembling tool bits 310, so that the two assembling tool bits 310 can move towards or away from each other.

[0044] Further, as shown in Figure 3 , Figure 4 In some embodiments, the assembling tool bit 310 is a vertically arranged roller 311, the roller 311 is located at the joint of the imitation pneumatic tire and the hub, one side of the roller 311 faces the hub and the other side of the roller 311 faces the imitation pneumatic tire; the roller 311 has a limiting surface 3111 facing the hub and a guide surface 3112 facing the imitation pneumatic tire, and the guide surface 3112 gradually inclines to the side away from the hub along the vertical direction away from the imitation pneumatic tire. The assembling tool bit 310 is arranged as a vertically arranged roller 311 to facilitate the assembly of the hub output by the wheel shaft and the imitation pneumatic tire preassembled on the hub, the roller 311 has a limiting surface 3111 facing the hub and a guide surface 3112 facing the imitation pneumatic tire, and the guide surface 3112 gradually inclines to the side away from the hub along the vertical direction away from the imitation pneumatic tire, that is, the thickness dimension of the roller 311 gradually changes in the vertical direction, which facilitates the insertion of the assembling tool bit 310 into the joint of the imitation pneumatic tire and the hub, and further facilitates the assembly of the hub and the imitation pneumatic tire, which is beneficial to improve the assembly efficiency and reduce the cost.

[0045] In some embodiments, as shown in Figure 3 , Figure 4 , Figure 5As shown, the assembling mechanism 300 further comprises a bracket 330 and a moving block 340, the bracket 330 is connected with the driving member 320; the fixed end of the driving member 320 is connected on the bracket 330, and the output end of the driving member 320 is movable along the vertical direction F1; the moving block 340 is connected on the output end of the driving member 320; the roller 311 is connected on the moving block 340. That is, the two driving members 320 are both arranged on the bracket 330, and can drive the two assembling tool bits 310 to move towards each other or move away from each other along the vertical direction F1, so that the roller 311 connected with the moving block 340 can be close to the hub and the imitation pneumatic tire, so that the assembling tool bit 310 is inserted into the joint of the imitation pneumatic tire and the hub.

[0046] Further, as shown in Figure 2 , the driving member 320 can be a pneumatic cylinder 321, the output end of the pneumatic cylinder 321 is connected with the moving block 340, so as to realize the movement of the roller 311.

[0047] In some embodiments, as shown in Figure 4 , Figure 5 , the roller 311 is rotatably connected with the moving block 340 around the rotation axis direction F2, which is parallel to the bearing surface 201, that is, in the process of contacting the hub and the imitation pneumatic tire to complete the assembly, the roller 311 can roll on the hub and the imitation pneumatic tire synchronously with the rotating positioning turntable 200, compared with the roller 311 without rolling, the roller 311 rotating can receive smaller friction, so as to complete the assembly of the hub and the imitation pneumatic tire more conveniently and quickly.

[0048] Specifically, in some embodiments, as shown in Figure 4 , Figure 5 , the surface of the moving block 340 away from the driving member 320 is provided with a first groove 341, the assembling mechanism 300 further comprises a rotation shaft 350, the rotation shaft 350 extends along the rotation axis direction F2, the rotation shaft 350 is located in the first groove 341 and connected with the inner wall surface of the first groove 341, and the roller 311 movably sheaths on the rotation shaft 350, that is, by movably sheathing the roller 311 on the rotation shaft 350, the roller 311 can be rotatable, so as to complete the assembly of the hub and the imitation pneumatic tire more conveniently and quickly. It can be understood that the first groove 341 has two opposite inner wall surfaces, as shown in Figure 5 , the two opposite inner wall surfaces are respectively a first inner wall surface 3411 and a second inner wall surface 3412. Further, in order to avoid the rotation shaft 350 from being separated from the bracket 330, a fixing shaft 360 for fixing the rotation shaft 350 can also be arranged, which can be arranged on the two side brackets connected with the rotation shaft 350, or can be arranged on only one side.

[0049] In some embodiments, as shown in Figure 1 , Figure 2As shown, the assembly mechanism 300 includes two, two assembly mechanisms 300 are respectively arranged on the left and right sides of the positioning turntable 200; two assembly mechanisms 300 act on the hub and the imitation pneumatic tire limited by the limiting clamp at the same time. Two assembly mechanisms 300 are respectively arranged on the left and right sides of the positioning turntable 200, which can act on the hub and the imitation pneumatic tire at the same time. Compared with only one assembly mechanism 300 for assembly, two assembly mechanisms 300 work at the same time, and the imitation pneumatic tire is balanced on both sides, so that the imitation pneumatic tire can be accurately and quickly assembled to the expected assembly position of the hub, avoiding the influence of the assembly effect caused by the single-sided force of the imitation pneumatic tire; in addition, the positioning turntable 200 can rotate a smaller angle, thereby shortening the assembly time, which is beneficial to improve the assembly efficiency. When the number of assembly mechanisms 300 is two, as shown in Figure 1 、 Figure 2 two assembly mechanisms 300 are distributed at intervals on the outer periphery of the positioning turntable 200, and the interval is 180°, that is, the extension lines of the two assembly mechanisms 300 are located on the same straight line. It can be understood that the number of assembly mechanisms 300 can also be more than two, for example, the assembly mechanism 300 can be three, four, etc. For example, when the number of assembly mechanisms 300 is three, three assembly mechanisms 300 are distributed at intervals on the outer periphery of the positioning turntable 200, and the interval is 120°, and so on. Considering the cost, the embodiment of the application can adopt two assembly mechanisms 300.

[0050] In some embodiments, as shown in Figure 3 the imitation pneumatic tire assembly jig 10 further includes an auxiliary limiting mechanism 400, and the auxiliary limiting mechanism 400 includes a tire limiting unit 410 arranged on both sides of the positioning turntable 200; one end of the tire limiting unit 410 towards the limiting clamp 210 has a circular arc limiting surface 411 matched with the outer surface of the imitation pneumatic tire, and the tire limiting unit 410 further includes a horizontal driving member 412 for driving the circular arc limiting surface 411 to approach or move away from the limiting clamp. The moving direction of the circular arc limiting surface 411 is the translation direction F3, and the circular arc limiting surface 411 is matched with the outer surface of the imitation pneumatic tire, which can increase the contact area between the tire limiting unit 410 and the imitation pneumatic tire, thereby enhancing the contact stability between the auxiliary limiting mechanism 400 and the imitation pneumatic tire, improving the stability of assembly, and facilitating the assembly of the imitation pneumatic tire and the hub; the horizontal driving member 420 can drive the circular arc limiting surface 411 to approach or move away from the limiting clamp 210, and by controlling the movement of the circular arc limiting surface 411, the limiting of the hub and the imitation pneumatic tire limited by the limiting clamp 210 can be realized.

[0051] In some embodiments, as shown in Figure 3As shown, the tire limiting unit 410 further comprises a roller 412 and a connecting piece 413, the arc limiting surface 411 can be formed on the roller 412, the roller 412 is arranged along the vertical direction F1, the connecting piece 413 has a second groove 4131, the roller 412 is located in the second groove 4131, and the roller is connected to the opposite inner walls of the second groove 4131, and the roller is located on the side of the roller 311 away from the positioning turntable 200 along the translation direction F3, the roller 412 can rotate around the vertical direction F1, and can assist in rotating the hub and the imitation pneumatic tire located on the rotatable positioning turntable 200, so as to improve the stability of the hub and the imitation pneumatic tire during rotation, thereby facilitating the assembly of the hub and the imitation pneumatic tire; the connecting piece 413 can connect two assembly mechanisms 300, and the two assembly mechanisms 300 are located on the two sides of the connecting piece 413, and then the roller 412 extends along the vertical direction F1 and is located on the side of the roller 311 away from the positioning turntable 200 along the translation direction F3, so as to avoid the contact between the roller 311 and the roller 412 affecting the assembly of the hub and the imitation pneumatic tire. It can be understood that the roller 412 can adopt a structure between the two supports 330 of the rotatable roller 311 connecting the two assembly mechanisms 300, which will not be described here. In order to avoid the influence of the connecting piece 413 on the movement of the roller 311 and the moving block 340 in the direction close to the hub and the imitation pneumatic tire, a through hole (not shown in the figure) can be provided on the connecting piece 413, and the roller 311 and the moving block 340 pass through the through hole to approach the hub and the imitation pneumatic tire and complete the assembly of the hub and the imitation pneumatic tire.

[0052] In some embodiments, as shown in Figure 3 As shown, the tire limiting unit 410 further comprises a guide rail 414 arranged along the moving direction F3 of the arc limiting surface 411. The tire limiting unit 410 comprises a guide rail 414 arranged along the moving direction F3 of the arc limiting surface 411, that is, the arc limiting surface 411 can move along the guide rail 414, which can improve the stability of the imitation pneumatic tire assembly jig 10. It can be understood that the connecting piece 413 is arranged on the guide rail 414, and further, the tire limiting unit 410 further comprises a sliding block 415, the connecting piece 413 is connected with the sliding block 415, and the sliding block 415 is slidably arranged on the guide rail 414 to realize the movement of the arc limiting surface 411.

[0053] In some embodiments, as shown in Figures 1-3As shown, two tire limiting units 410 are located on the left and right sides of the positioning turntable 200, and the horizontal driving member 420 simultaneously drives the circular arc limiting surface 411 and the assembly tool bit 310 to move horizontally to approach or move away from the limiting clamp 210. By locating the two tire limiting units 410 on the left and right sides of the positioning turntable 200, the left and right sides of the hub and the imitation pneumatic tire can be simultaneously limited, which can improve the accuracy of the limiting and the stability of the imitation pneumatic tire assembly jig 10 compared to one tire limiting unit 410. By setting the horizontal driving member 420 to simultaneously drive the circular arc limiting surface 411 and the assembly tool bit 310 to move horizontally along the translation direction F3 to approach or move away from the limiting clamp 210, the two tire limiting units 410 and the two assembly mechanisms 300 located on the left and right sides of the positioning turntable 200 can be simultaneously controlled, which is convenient for operation and control compared to manual control, has higher accuracy, and can improve the stability of the hub and the imitation pneumatic tire assembly. It can be understood that the horizontal driving member 420 can also be a pneumatic cylinder.
