Description

Technical Field

[0001] The utility model belongs to the technical field of tire assembly equipment, and particularly refers to a tire mounting device for bicycle solid tires. Background Technique

[0002] On the market, a solid outer tire form is usually adopted to be installed on the outside of the wheel hub. This method results in a relatively heavy overall weight of the tire and a relatively low driving speed. With the development of the times, the traditional solid tire structure cannot meet relatively special use environments. There appears a solid tire for track racing bicycles on the market, which includes a plastic support ring assembled in the wheel groove of the wheel hub, an outer tire assembled with a sponge ring, and the outer tire is assembled in the wheel groove of the wheel hub to form a bicycle wheel assembly. The sponge ring and the plastic support ring play a role in protecting the wheel hub.

[0003] However, for the assembly of such solid tires, manual assembly using traditional tools is usually adopted at present. The assembly efficiency is low, and at the same time, the dynamic balance effect of the tires after manual assembly is relatively poor, with a large error. Summary of the Invention

[0004] The purpose of the utility model is to provide a tire mounting device for bicycle solid tires, which provides convenience for assembling bicycle solid tires through an integrated device, greatly improves the assembly efficiency, and has higher assembly accuracy than manual assembly.

[0034] The following further describes the utility model with specific embodiments in conjunction with the drawings. Refer to Figure 1 — Figure 5 :

[0035] A bicycle solid tire mounting device includes a bottom plate 1, on which a turntable 2 driven by a servo motor at the bottom is arranged. A tensioning mechanism 3, a first pressing mechanism 4 and a second pressing mechanism 5 fixed on the bottom plate 1 are arranged outside the turntable 2;

[0036] A hub column 20 for horizontally placing the hub is provided in the middle of the turntable 2, and a limit fixture 21 for fixing the hub is provided on the turntable 2. A retaining wheel 22 is provided at the upper end of the limit fixture 21;

[0037] The tensioning mechanism 3 includes a tensioning platform 30 fixed on the bottom plate 1. A tensioning roller 32 that moves along the radial and longitudinal directions of the turntable 2 is arranged on the tensioning platform 30 through a sliding component 31, and the tensioning roller 32 is horizontally placed;

[0038] The first pressing mechanism 4 includes a first pressing frame 40 arranged outside the turntable 2. An upper pressing fixing plate 41 that moves up and down by means of a motor-driven lead screw is arranged on the first pressing frame 40. A plurality of upper pressing tire rollers 42 for abutting against the upper end surface of the tire are arranged at the lower end of the upper pressing fixing plate 41;

[0039] The second pressing mechanism 5 includes a second pressing frame 50 arranged outside the turntable. A sliding plate 51 that moves up and down by means of a motor-driven lead screw is arranged on the second pressing frame 50. A horizontally placed pressing motor 52 is fixed on the sliding plate 51, and a pressing wheel 53 for pressing the tire shoulder is fixed on the output shaft of the pressing motor 52.

[0040] The specific tire mounting operation is as follows:

[0041] Pre-place the hub 6 on the turntable 2 and fix it by means of the limit fixture. Place the outer tire 7 flat above the hub 6. The outer wheel wall of the tensioning roller 32 abuts against the inner ring of the lower tire shoulder. By rotating the turntable 2 one circle, the lower tire shoulder of the outer tire 7 is installed into the outer wheel groove of the hub.

[0042] The tensioning roller is lifted up. The plastic support ring 9 is sleeved above the hub, and the pressing roller is used again to make the turntable rotate one circle and install the plastic support ring into the wheel groove of the hub.

[0043] Put the sponge ring above the hub, and one end is abutted by the retaining wheel 22. Press down the upper pressing tire roller and rotate the turntable one circle to fill the sponge ring 8 into the outer tire.

[0044] Lift up the upper pressing tire roller 42, and the pressing motor drives the pressing wheel 53 to move downward, so that the upper tire shoulder of the outer tire is installed in the wheel groove of the hub after the turntable 2 rotates one circle. During installation, the pressing roller keeps one end fixed, so that the upper tire shoulder of the tire can be completely installed in the wheel groove of the hub after rotating one circle.

[0045] In addition, in the above structure, the number of rotation circles can be judged by rotating the limit fixture 21 one circle. And after rotating one circle, a reset form, that is, a reverse rotation form, is adopted. This method is convenient for accurate positioning during installation.

[0046] The outer tire is a non-solid tire.

[0047] Preferably, the limiting fixture 21 extends into the rim gap inside the wheel hub. A slide bar 23 is fixed to the end of the wheel stop 22, and a chute 24 for the slide bar 23 to move in the radial direction of the turntable 2 is provided at the top of the limiting fixture 21.

[0048] In the above structure, different tires have different inner ring sizes. By adjusting the wheel stop 22 on the limiting fixture, more tires of different sizes can be used.

[0049] Preferably, a number of lower tire pressing rollers 43 are provided at the lower end of the first lower pressing frame 40 and are located below the upper tire pressing rollers 42. The a number of lower tire pressing rollers 43 and the upper tire pressing rollers 42 are both arc-shaped, and the longitudinal positions of their arc centers are the same as the center of the turntable 2.

[0050] Making the a number of lower tire pressing rollers 43 and the upper tire pressing rollers 42 arc-shaped can better fit the sidewall of the tire and be more firmly abutted during installation; at the same time, a number of lower tire pressing rollers that can fit the lower tire shoulder are also placed below the pressing wheel.

[0051] Preferably, the sliding assembly 31 includes a tensioning cross slide 310 provided on the tensioning platform 30 and sliding in the radial direction of the turntable 2. A tensioning longitudinal slide 311 that slides longitudinally is provided above the tensioning cross slide 310. A longitudinally arranged fixed shaft 320 is penetrated through the top of the tensioning roller 32, and the top of the fixed shaft 320 is fixedly connected to the tensioning longitudinal slide 311.

[0052] In the above structure, an annular groove is provided on the side wall of the tensioning roller 32, which can facilitate the installation of the plastic support ring. Since the tensioning mechanism abuts one end of each part during the installation process, adjustments at multiple positions are required.

[0053] Preferably, a lead screw for driving the slide plate 51 to move in the radial direction of the turntable 2 is provided on the back of the slide plate 51, and a hand crank 54 for driving the lead screw to rotate is provided at one end of the lead screw. The use of the hand crank can make fine adjustments, thus facilitating the installation of the upper tire shoulder of the tire.

[0054] Preferably, the first lower pressing mechanism 4 is located between the tensioning mechanism 3 and the second lower pressing mechanism 5. The structure is more optimized.

[0055] Preferably, a frame is provided at the bottom of the bottom plate, which is integrally wrapped with a housing, and a certain main control adjustment operation platform is also provided to control each motor.

[0056] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
