Description

Technical Field

[0001] This utility model relates to the field of automotive repair technology, specifically to a wheel lifting device for wheel dynamic balance testing. Background Technology

[0002] Wheel dynamic balancing is a process of evaluating car tires and rims. Its main purpose is to ensure that the center of gravity of the wheel is even when it rotates, and to prevent vibration and abnormal wear caused by imbalance. The test usually uses special equipment to measure the static and dynamic imbalance of the tires, and adjusts the balance by adding counterweights to improve driving stability, driving comfort and tire life.

[0003] When performing dynamic balancing tests on car wheels, a wheel dynamic balancer is required. Before starting the test, the wheel often needs to be moved onto the balance shaft of the wheel dynamic balancer. Usually, workers manually move the wheel onto the balance shaft of the wheel dynamic balancer. Manual moving is not only time-consuming and laborious, but also carries the risk of slipping and falling, injuring the feet. Utility Model Content

[0004] The purpose of this invention is to provide a wheel lifting device for wheel dynamic balance detection, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A wheel lifting device for dynamic balancing testing includes a column, a lifting seat, a mounting frame, and a pair of support rollers. The column is vertically fixed on the ground and located on one side of the balance shaft of the dynamic balancing instrument. The lifting seat is arranged on the side of the column facing the balance shaft. A drive mechanism is provided on the column to drive the lifting seat to adjust its height. The mounting frame is fixed on the end of the lifting seat, and the two support rollers are symmetrically arranged on the side of the mounting frame.

[0007] Therefore, by standing the tire upright and rolling it between the two support rollers, the operating drive mechanism moves the lifting seat upward. After the two support rollers contact the two sides of the tire, the tire can be supported and raised together until the hole on the tire is roughly aligned with the position of the balance shaft. Then, the tire is manually transferred to the balance shaft, which achieves the effect of assisting in lifting, replacing the traditional manual lifting, saving time and effort, and reducing the labor intensity of the workers.

[0008] Furthermore, the two support rollers are arranged on the side of the mounting frame facing the balance shaft, and the balance shaft is positioned centered relative to the two support rollers.

[0009] Furthermore, the mounting bracket has a horizontally extending guide groove on its side, in which a bidirectional threaded rod is rotatably mounted. One end of the mounting bracket is fixed with a drive motor, and the output shaft of the drive motor is fixedly connected to the bidirectional threaded rod. Two nut seats are symmetrically and slidably mounted in the guide groove, and the two nut seats are respectively threaded and matched on both sides of the bidirectional threaded rod. A vertically downward extending mounting plate is fixed to the end of each of the two nut seats, and a support roller is installed on the side of the corresponding mounting plate.

[0010] Furthermore, shafts are rotatably mounted on the sides of both mounting plates, and two support rollers are mounted on the shafts in a corresponding manner.

[0011] Furthermore, one side of the two support rollers is provided with a telescopic channel, and the other side is provided with a through hole that communicates with the telescopic channel. The inner diameter of the telescopic channel is larger than the inner diameter of the through hole. The shaft slides through the through hole and extends into the telescopic channel. An anti-detachment cap is fixed on the end of the shaft. The outer diameter of the anti-detachment cap is larger than the inner diameter of the telescopic channel.

[0012] Furthermore, the side of the column is provided with a sliding groove, and the end of the lifting seat away from the mounting frame is slidably installed in the sliding groove.

[0013] Furthermore, the drive mechanism includes an electric push cylinder, a slide rod, and a connecting arm. The electric push cylinder is vertically fixed to the side of the column. The slide rod is vertically arranged in the slide groove, with its bottom end fixedly connected to the lifting seat and its top end sliding through and extending to the top of the column. One end of the connecting arm is fixed to the end of the telescopic rod of the electric push cylinder, and the other end is fixed to the top of the slide rod.

[0014] Furthermore, vertically extending guide rods are fixed to both sides of the column via side brackets, and L-shaped arms are fixed to both sides of the lifting seat, with the L-shaped arms slidingly fitted onto the guide rods in a corresponding manner.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model stands the tire upright and rolls it between two support rollers. The operating drive mechanism moves the lifting seat upward. After the two support rollers contact the two sides of the tire, the tire can be supported and raised together until the hole on the tire is roughly aligned with the position of the balance shaft. Then, the tire is manually transferred to the balance shaft, thereby achieving the effect of auxiliary lifting. This replaces the traditional manual lifting, saving time and effort and reducing the labor intensity of workers.

[0017] 2. This utility model uses a drive motor to operate, and its output shaft drives a bidirectional threaded rod to rotate. The rotating bidirectional threaded rod drives two nut seats to slide closer or further apart along the inner wall of the guide groove. Under the connection of the mounting plate, it drives two support rollers to move synchronously, thereby adjusting the distance between the two support rollers to accommodate tires of different diameters and effectively improving the versatility of this device.

[0018] 3. After the tire is raised to the required height, this utility model pulls the tire towards the balance shaft. Under the action of friction, the support roller can slide along the shaft, which helps to transfer the tire to the balance shaft. This reduces the time spent manually moving the tire, ensures a smoother transfer process, reduces the probability of slippage and loss of control, and improves the safety of tire transfer.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0027] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0028] Please see Figures 1-5 The present invention provides a wheel lifting device for wheel dynamic balancing testing, including a column 1, a lifting seat 2, a mounting frame 4 and a pair of support rollers 5. The column 1 is vertically fixed on the ground and located on one side of the balance shaft of the dynamic balancing instrument. The lifting seat 2 is arranged on the side of the column 1 facing the balance shaft. The column 1 is provided with a drive mechanism 3, which is used to drive the lifting seat 2 to adjust its height. The mounting frame 4 is fixed on the end of the lifting seat 2, and the two support rollers 5 are symmetrically arranged on the side of the mounting frame 4.

[0029] When using this lifting device for dynamic balancing testing, firstly, operate the drive mechanism 3 to lower the lifting seat 2 to its limit position, so that the two support rollers 5 are lowered to the bottom. Stand the tire upright and roll it between the two support rollers 5. Since the support rollers 5 are lowered to the bottom and in contact with the ground, it is easier to roll the tire between the two support rollers 5. Then, operate the drive mechanism 3 to move the lifting seat 2, the mounting frame 4 and the support rollers 5 upward. After the two support rollers 5 contact the two sides of the tire, the tire can be supported and raised together until the hole on the tire is roughly aligned with the position of the balance shaft. Then, manually transfer the tire to the balance shaft, thereby achieving the effect of auxiliary lifting, replacing traditional manual lifting, saving time and effort, and reducing the labor intensity of workers.

[0030] Specifically, the two support rollers 5 are arranged on the side of the mounting frame 4 facing the balance shaft, and the balance shaft is centered relative to the two support rollers 5. This ensures that when the two support rollers 5 support and lift the tire, the balance shaft is aligned with the hole on the tire as much as possible, making tire transfer easier and less strenuous.

[0031] Specifically, the mounting frame 4 has a horizontally extending guide groove 41 on its side. A bidirectional threaded rod 42 is rotatably installed in the guide groove 41. A drive motor 43 is fixed to one end of the mounting frame 4. The output shaft of the drive motor 43 is fixedly connected to the bidirectional threaded rod 42. Two nut seats 44 are symmetrically and slidably installed in the guide groove 41. The two nut seats 44 are threadedly matched and fitted on both sides of the bidirectional threaded rod 42. A vertically downward extending mounting plate 45 is fixed to the end of each of the two nut seats 44. The support rollers 5 are installed on the side of the corresponding mounting plates 45. When the drive motor 43 works, its output shaft drives the bidirectional threaded rod 42 to rotate. The rotating bidirectional threaded rod 42 drives the two nut seats 44 to slide closer to or further away from each other along the inner wall of the guide groove 41. Under the connection of the mounting plate 45, the two support rollers 5 move synchronously, thereby adjusting the distance between the two support rollers 5 to accommodate tires of different diameters and effectively improving the versatility of the device.

[0032] Specifically, shafts 51 are rotatably mounted on the sides of both mounting plates 45, and two support rollers 5 are mounted on the shafts 51 in a corresponding manner. By mounting the support rollers 5 on the rotatably mounted shafts 51, the support rollers 5 have the ability to rotate, and thus can rotate after contacting the tire, thereby reducing the friction between the support rollers and the tire.

[0033] Specifically, one side of each of the two support rollers 5 is provided with a telescopic channel 501, and the other side is provided with a through hole 502 that communicates with the telescopic channel 501. The inner diameter of the telescopic channel 501 is larger than the inner diameter of the through hole 502. The shaft 51 slides through the through hole 502 and extends into the telescopic channel 501. An anti-detachment cap 53 is fixed on the end of the shaft 51. The outer diameter of the anti-detachment cap 53 is larger than the inner diameter of the telescopic channel 501. After the tire is raised to the required height, by pulling the tire towards the balance shaft, the support roller 5 can be driven to slide along the shaft 51 under the action of friction, which helps to transfer the tire to the balance shaft and reduces the time spent manually moving the tire, ensuring a smoother transfer process. It also reduces the probability of slippage and loss of control, and improves the safety of tire transfer.

[0034] Specifically, the side of the column 1 is provided with a sliding groove 21, and the end of the lifting seat 2 away from the mounting frame 4 is slidably installed in the sliding groove 21, so that the lifting seat 2 has the ability to slide up and down.

[0035] Specifically, the drive mechanism 3 includes an electric push cylinder 31, a slide rod 32, and a connecting arm 33. The electric push cylinder 31 is vertically fixed to the side of the column 1. The slide rod 32 is vertically arranged in the slide groove 21, and its bottom end is fixedly connected to the lifting seat 2. Its top end slides through and extends to the top of the column 1. One end of the connecting arm 33 is fixed to the end of the telescopic rod of the electric push cylinder 31, and the other end is fixed to the top end of the slide rod 32. Through the telescopic operation of the electric push cylinder 31, under the fixed connection of the connecting arm 33, the slide rod 32 and the lifting seat 2 can be driven to move up and down synchronously, thereby providing a stable drive for the lifting adjustment of the lifting seat 2.

[0036] Specifically, vertically extending guide rods 12 are fixed to both sides of the column 1 via side brackets 11. L-shaped arms 22 are fixed to both sides of the lifting seat 2. The L-shaped arms 22 are slidably fitted onto the guide rods 12 in a corresponding manner. When the lifting seat 2 is raised or lowered, the L-shaped arms 22 can be driven to slide synchronously along the guide rods 12. The sliding cooperation between the L-shaped arms 22 and the guide rods 12 provides limiting guidance and support for the raising and lowering of the lifting seat 2, ensuring that the raising and lowering of the lifting seat 2 is smoother and more stable.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
