Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing technology, and specifically to a rubber-coated idler roller mechanism. Background Technology
[0002] In automobile production, rubber-coated roller mechanisms are commonly used as the driving unit during the automobile assembly process. A rubber-coated roller mechanism includes two rubber-coated wheels located on either side, and a support shaft passing between the two wheels to support their suspended rotation. When driving the vehicle, multiple rubber-coated roller mechanisms are arranged parallel and spaced along the vehicle's direction of travel. The rubber-coated wheels are driven to rotate by a pulley drive mechanism. When the vehicle wheels contact the rubber surface of the rubber-coated wheels, they can move forward under the drive of the rubber-coated roller mechanism.
[0003] The disadvantages of existing rubber-coated idler roller mechanisms are:
[0004] 1. To prevent lateral (axial) displacement of the vehicle during operation, baffles are installed on both sides of the rubber-coated wheel on at least one side. In the prior art, the baffles are fixed to the rubber-coated wheel with bolts. During the assembly of the baffles, it is necessary to first machine screw holes on the rubber-coated wheel and then machine fixing holes on the baffles. The fixing holes and screw holes are aligned and then the bolts are fixed one by one. The process is cumbersome, and it is common for the screw holes and fixing holes on the baffles to be misaligned due to insufficient machining accuracy, which leads to the bolts not being able to be installed smoothly. The baffle assembly structure is complex, the manufacturing cost is high, and the assembly efficiency is low.
[0005] 2. Each of the rubber-coated wheels on both sides is connected to a set of pulleys (each set of pulleys includes two pulleys). The two sets of pulleys drive the corresponding rubber-coated wheels to rotate, resulting in redundancy in the pulley transmission mechanism and poor synchronization of the rotation of the rubber-coated wheels on both sides. Utility Model Content
[0006] The purpose of this utility model is to provide a rubber-coated idler mechanism to solve the problems of complex baffle assembly structure, high manufacturing cost and low assembly efficiency of existing rubber-coated idler mechanisms.
[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0008] A rubber-coated idler roller mechanism includes a first rubber-coated roller, a second rubber-coated roller, and a support shaft. The first rubber-coated roller is located at one end of the support shaft and is connected to the support shaft through a first bearing. The second rubber-coated roller is located at the other end of the support shaft and is connected to the support shaft through a second bearing.
[0009] It also includes baffles disposed on both sides of the first rubber-coated wheel, the baffles being connected to the first rubber-coated wheel via a stamping and riveting structure;
[0010] It also includes a pulley assembly and a synchronizing tube. The synchronizing tube is sleeved on the outer periphery of the support shaft and is fixedly connected to the first rubber-coated wheel, the pulley assembly, and the second rubber-coated wheel.
[0011] As a further improvement of this utility model, connecting pieces are provided on the two sides of the first rubber-coated wheel, and the suspended ends of the connecting pieces are folded outward to form a riveting structure to fix the baffle.
[0012] As a further improvement of this utility model, the pulley group is located close to the second rubber-coated wheel, and the pulley group includes two pulleys.
[0013] As a further improvement of this utility model, the synchronization tube is fixedly connected to the first rubber-coated wheel, the pulley group, and the second rubber-coated wheel by welding.
[0014] As a further improvement of this utility model, there is a gap between the inner wall of the synchronization tube and the outer wall of the support shaft.
[0015] As a further improvement of this utility model, the outer circumferential surfaces of the first rubber-coated wheel and the second rubber-coated wheel are both covered with an anti-slip rubber layer.
[0016] As a further improvement of this utility model, the baffle is tightly fitted to the first rubber-coated wheel.
[0017] Compared with the prior art, the technical advantages of this utility model are as follows:
[0018] This utility model uses a riveting structure to fix the baffle. After the baffle is fitted onto the riveting pre-reserved structure (such as a connecting piece), the riveting structure can be formed by stamping with a riveting die. The baffle assembly structure is simple, the manufacturing cost is low, and the assembly efficiency is high.
[0019] The first rubber-coated wheel, the pulley set, and the second rubber-coated wheel are connected by a synchronizing pipe. The synchronizing pipe can transmit the torque of the pulley set to the first rubber-coated wheel and the second rubber-coated wheel synchronously. Therefore, only one set of pulley sets is needed to drive the first rubber-coated wheel and the second rubber-coated wheel to rotate, which simplifies the pulley transmission mechanism and ensures good rotational synchronization between the first rubber-coated wheel and the second rubber-coated wheel.

[0024] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.
[0025] Please see Figures 1 to 4 A rubber-coated roller mechanism includes a first rubber-coated roller 1, a second rubber-coated roller 2, and a support shaft 3. The first rubber-coated roller 1 is located at one end of the support shaft 3 and is connected to the support shaft 3 via a first bearing 4. The second rubber-coated roller 2 is located at the other end of the support shaft 3 and is connected to the support shaft 3 via a second bearing 5. The first rubber-coated roller 1 and the second rubber-coated roller 2 can rotate in suspension under the support of the support shaft 3.
[0026] It also includes baffles 6 disposed on both sides of the first rubber-coated wheel 1, the baffles 6 being connected to the first rubber-coated wheel 1 via a stamping and riveting structure. The baffles 6 are used to limit the movement of the vehicle's wheels to prevent lateral (axial) displacement of the vehicle during travel. Assembling the baffles 6 using a stamping and riveting structure has the advantages of simple assembly structure, low manufacturing cost, and high assembly efficiency.
[0027] It also includes a pulley assembly 7 and a synchronizing pipe 8. The synchronizing pipe 8 is sleeved on the outer periphery of the support shaft 3. The synchronizing pipe 8 is fixedly connected to the first rubber-coated wheel 1, the pulley assembly 7, and the second rubber-coated wheel 2 by welding. The pulley assembly 7 is located close to the second rubber-coated wheel 2, and the pulley assembly 7 includes two pulleys.
[0028] When used to drive a car, multiple rubber-coated roller mechanisms are arranged in parallel and spaced along the direction of the car's travel. The two pulleys of the pulley group 7 are respectively connected to the pulleys of the upper and lower level rubber-coated roller mechanisms via belts, so that each rubber-coated roller mechanism can operate under the drive of a power mechanism (e.g., an electric motor). When the car's wheels come into contact with the first rubber-coated wheel 1 and the second rubber-coated wheel 2, they rotate and move forward to carry out car assembly operations.
[0029] Furthermore, connecting pieces 9 protrude from both sides of the first rubber-coated wheel 1, and the suspended ends of the connecting pieces 9 are folded outward to form a riveting structure to fix the baffle 6.
[0030] The connecting piece 9 and the metal wheel body of the first rubber-coated wheel 1 are an integral structure. Before stamping, the connecting piece 9 is cylindrical, and the baffle 6 fits onto the connecting piece 9 through the circular hollow in the middle.
[0031] By stamping the connecting pieces 9 one by one with a stamping and riveting die, the suspended ends of the connecting pieces 9 can be folded outward, and the two baffles 6 can be firmly fixed on the first rubber-coated wheel 1.
[0032] Furthermore, the baffle 6 is tightly fitted to the first rubber-coated wheel 1. There is no gap between the baffle 6 and the anti-slip rubber layer 10 of the first rubber-coated wheel 1, and the outwardly folded stamped surface of the connecting piece 9 is flat and has good roundness.
[0033] Furthermore, there is a gap between the inner wall of the synchronizing tube 8 and the outer wall of the support shaft 3. The inner wall of the synchronizing tube 8 and the outer wall of the support shaft 3 do not contact each other, thereby avoiding friction between the synchronizing tube 8 and the support shaft 3 during rotation, which would increase rotational resistance.
[0034] Furthermore, both the first rubber-coated wheel 1 and the second rubber-coated wheel 2 are covered with an anti-slip rubber layer 10 on their outer circumferential surfaces. The anti-slip rubber layer 10 is made of rubber or polyurethane material with a high coefficient of friction, and is used to increase the friction between the rubber layer and the vehicle wheels.
[0035] Compared with the prior art, the technical advantages of this utility model are as follows:
[0036] This utility model fixes the baffle 6 through a stamping and riveting structure. After the baffle 6 is fitted onto the pre-stamping and riveting structure (such as the connecting piece 9), the stamping and riveting structure can be formed by stamping with a stamping and riveting die. The baffle 6 has a simple assembly structure, low manufacturing cost and high assembly efficiency.
[0037] The first rubber-coated wheel 1, the pulley group 7, and the second rubber-coated wheel 2 are connected by the synchronizing pipe 8. The synchronizing pipe 8 can transmit the torque of the pulley group 7 to the first rubber-coated wheel 1 and the second rubber-coated wheel 2 synchronously. Therefore, only one pulley group 7 is needed to drive the first rubber-coated wheel 1 and the second rubber-coated wheel 2 to rotate, which simplifies the pulley transmission mechanism and ensures good rotational synchronization of the first rubber-coated wheel 1 and the second rubber-coated wheel 2.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
