[0002] In the manufacturing process of bicycles, tires need to be assembled. Current tire assembly methods involve manually pressing the rubber tire into the rim, which is time-consuming and labor-intensive, resulting in low processing efficiency.

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035] like Figures 1 to 4 As shown, this embodiment proposes a tire assembly device, including:

[0036] Support assembly 11, having a rotating platform 12 for mounting wheel hub 13;

[0037] The first pressing module 14 is located above the rotating platform 12 and is used to press the rubber tire 24 into the wheel hub 13.

[0038] The lifting assembly 15 has an output end that moves in a vertical direction, and a first pressing module 14 is installed on the output end of the lifting assembly 15.

[0039] Working principle: Usually, the rubber tire 24 is first installed into the wheel hub 13 by workers manually. This process is the initial installation, which is relatively simple and quick. It only serves to initially position the rubber tire 24 and the wheel hub 13. The rubber tire 24 and the wheel hub 13 are not fully engaged. At this time, there will be local protrusions in the rubber tire 24, and it is not fully installed into the wheel hub 13.

[0040] The rubber tire 24 and wheel hub 13 are then placed together on the rotating platform 12. The lifting assembly 15 drives the first clamping module 14 downwards, applying pressure to the rubber tire 24. Simultaneously, the rotating platform 12 rotates, causing the rubber tire 24 and wheel hub 13 to rotate as well, thus ensuring the first clamping module 14 fully compresses the rubber tire 24. This solution solves the technical problem of difficult installation of the rubber tire 24 and has the advantages of saving time and effort.

[0041] As one embodiment of this invention, a support base 16 is also included, on which a lifting assembly 15 and a support assembly 11 are respectively installed.

[0042] The function of the support base 16 in this scheme is only to install and support the support component 11, the first clamping module 14 and the lifting component 15.

[0043] As one implementation of this embodiment, the support component 11 includes:

[0044] The first support plate 17 is fixed on the support base 16, and a rotating platform 12 is rotatably provided on the first support plate 17.

[0045] Motor 18 is mounted on the first support plate 17. Motor 18 has a rotatable output shaft. The output shaft of motor 18 is fixedly connected to the rotating platform 12 and is used to drive the rotating platform 12 to rotate.

[0046] In this design, the rotating platform 12 is driven by the motor 18.

[0047] As one embodiment of this invention, the rotating platform 12 is cylindrical, and the axis of the rotating platform 12 coincides with the axis of the output shaft of the motor 18. The top end face of the rotating platform 12 is used to support the hub 13.

[0048] In this design, the diameter of the top circular plane of the rotating platform 12 is smaller than the outer diameter of the hub 13, and the diameter of the rotating platform 12 is larger than the inner diameter of the hub 13. This design prevents the rotating platform 12 from contacting the rubber surface of the rubber tire 24. It is primarily used in conjunction with the third rotating wheel 28 to prevent contact between the third rotating wheel 28 and the rotating platform 12.

[0049] Furthermore, a limit post 19 is fixed on the upper end face of the rotating platform 12, and multiple limit posts 19 respectively abut against the inner ring surface of the hub 13.

[0050] As one embodiment of this invention, the first clamping module 14 includes:

[0051] The first mounting plate 20 is fixed to the output end of the lifting assembly 15.

[0052] The second mounting plate 21 is fixed to the lower surface of the first mounting plate 20 by a fixing rod 39, and a fixing plate 40 is fixed to the lower surface of the second mounting plate 21 by a connector.

[0053] The first clamping member 22 is fixed on the fixed plate 40. The first clamping member 22 has a first rotating wheel 23. The circumferential surface of the first rotating wheel 23 is used to compress the rubber tire 24.

[0054] The technical advantage of this solution is that the circumference of the first rotating wheel 23 compresses the rubber tire 24.

[0055] In one embodiment of this invention, the first pressing module 14 further includes a second pressing member 25, which is mounted on the fixed plate 40. The second pressing member 25 has a second rotating wheel 26, the flat surface of which is used to compress the rubber tire 24 and the wheel hub 13. The technical advantage of this solution is that it enables the rubber tire 24 and the wheel hub 13 to fit together fully.

[0056] As one embodiment of this example, the lower surface of the second mounting plate 21 is provided with a second pressing module 27, and the second pressing module 27 has a third rotating wheel 28 for squeezing the outer periphery of the rubber tire 24.

[0057] The technical effect of this solution is that by pressing the circumferential surface of the rubber tire 24 with the third rotating wheel 28, the rubber tire 24 can be fully pressed into the wheel hub 13.

[0058] In one embodiment of this invention, an annular mounting base 29 is rotatably mounted below the second mounting plate 21, and the end of the second pressing module 27 away from the third rotating wheel 28 is hinged to the second mounting plate 21. The second pressing module 27 and the annular mounting base 29 are movably connected.

[0059] The technical advantage of this solution is that the angle of the second pressing module 27 can be adjusted by rotating the annular mounting base 29, so that the third rotating wheel 28 can press the circumference of the rubber tire 24.

[0060] Furthermore, the third wheel 28 has a groove on its circumference for fitting with the rubber tire 24.

[0061] As one embodiment of this invention, the second mounting plate 21 is provided with an arc-shaped groove 30;

[0062] A sliding rod 31 is vertically fixed on the annular mounting base 29. The sliding rod 31 passes through the arc-shaped groove 30 and can slide along the arc-shaped groove 30. A limiting block 32 is provided at the upper end of the sliding rod 31.

[0063] The second mounting plate 21 is provided with a telescopic component 33. One end of the telescopic component 33 is rotatably mounted on the second mounting plate 21, and the other end of the telescopic component 33 is hinged to the limiting block 32. The telescopic component 33 is a cylinder.

[0064] As one embodiment of this invention, the second clamping module 27 is provided with a waist-shaped opening 34, and a push rod 35 is fixed on the annular mounting base 29. The push rod 35 is slidably disposed in the waist-shaped opening 34.

[0065] Working principle: Since the second mounting plate 21 may rotate, when the telescopic component 33 works, it will drive the limit block 32 to move. The limit block 32 drives the annular mounting seat 29 to rotate through the sliding rod 31. At this time, the pushing rod 35 follows the movement. Under the action of the waist-shaped opening 34, the pushing rod 35 adjusts the angle of the second pressing module 27, so that the third rotating wheel 28 can press the circumference of the rubber tire 24.

[0066] As one embodiment of this invention, the lifting assembly 15 includes a second support plate 36 and a hydraulic cylinder 37. The second support plate 36 is fixed on the support base 16, and the hydraulic cylinder 37 is mounted on the support base 16. A first mounting plate 20 is mounted on the piston rod of the hydraulic cylinder 37. The first mounting plate 20 is slidably inserted into the guide hole of the second support plate 36 through a guide rod 38.

[0067] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
