Description

Technical Field

[0001] This utility model relates to the field of tire positioning technology, specifically a rapid positioning device for a tire dynamic balancing machine. Background Technology

[0002] Tire dynamic balancing machines are used to detect and correct uneven mass distribution in the tire and wheel hub assembly. When a tire rotates at high speed, uneven mass distribution can lead to increased vibration and noise, and even cause wear on the vehicle's suspension system, reduced driving safety and comfort. When inspecting a tire, it is necessary to fix the tire in place using a quick positioning device.

[0003] A search of Chinese patent CN218067046U reveals an adjustable clamping and positioning device for tire damage inspection. The device includes a base, on which a motor is mounted. The output shaft of the motor passes through the base and is rotatably connected to it. A connecting sleeve is slidably fitted onto the outside of the output shaft, and a lead screw is fixedly connected to the connecting sleeve. This invention features a base with a motor driving the lead screw to rotate. Two moving blocks on the lead screw undergo lateral displacement through threaded movement with the lead screw, causing the blocks to move towards or away from each other. When the blocks move towards each other, they guide a clamping plate, which in turn moves a clamping sleeve, thus stably clamping the tire. Furthermore, by controlling the displacement of the moving blocks, the distance between the clamping sleeves can be adjusted to accommodate tires of different sizes, increasing applicability.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. During the tire positioning process, it is not convenient to insert the tire into the wheel hole, it is not convenient to quickly position the tire, and after the tire dynamic balancing work is completed, it is not convenient to brake the tire immediately, and the testing cycle is long. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid positioning device for a tire dynamic balancing machine.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a rapid positioning device for a tire dynamic balancing machine, including a fixed plate. A pair of first hydraulic cylinders are symmetrically arranged on the fixed plate. A fixed frame is fixedly installed on the telescopic end of each hydraulic cylinder. A movable rod is rotatably installed on the fixed frame. A positioning mechanism is provided on the movable rod. The positioning mechanism includes a turntable seat fixedly installed on the movable rod. A plurality of first circular sleeves are fixedly installed on the turntable seat. A first spring is connected to the inner wall of each first circular sleeve. The end of the first spring is connected to an insert rod that is slidably connected to the first circular sleeve.

[0008] Each of the fixed frames is provided with a support mechanism, the support mechanism including a pair of side frames symmetrically fixedly installed on the fixed frame, each of the side frames is provided with an abutment component, each pair of abutment components is provided with a ring plate, a pad ring is fixedly installed on the ring plate, and a drive component is provided between the fixed frame and the ring plate.

[0009] A pair of braking mechanisms are symmetrically arranged on the fixed plate. Each braking mechanism includes a second hydraulic cylinder mounted on the fixed plate. A bracket is fixedly installed on the telescopic end of the second hydraulic cylinder, and a braking component is mounted on the bracket.

[0010] Furthermore, a rotating sleeve is slidably mounted on each of the aforementioned movable rods.

[0011] Furthermore, the abutment assembly includes a second circular sleeve fixedly mounted on the side frame.

[0012] Furthermore, the abutment assembly also includes a second spring connected to the inner wall of the second sleeve, and the end of the second spring is connected to a telescopic block that is slidably connected to the second sleeve. Each pair of telescopic blocks is fixed together to the ring plate.

[0013] Furthermore, the drive assembly includes a drive motor mounted on the fixed frame, a lead screw fixedly mounted on the output end of the drive motor, and a threaded block adapted to the lead screw fixedly mounted on the ring plate.

[0014] Furthermore, the braking assembly includes a brake roller rotatably mounted on the bracket, and two torsion springs are connected between the bracket and the brake roller.

[0015] Furthermore, the tire body is held together by a pair of turntable seats and a pair of washer rings, and the plurality of inserts are located inside the wheel hole of the tire body.

[0016] The above-described solution of this utility model has at least the following beneficial effects:

[0017] 1. In this utility model, by controlling the extension end of the first hydraulic cylinder to extend, the fixing frame, through the side frame, the second sleeve, the second spring, the telescopic block, and the ring plate, drives the pad ring to clamp the tire body. At the same time, the turntable seat, through the first sleeve and the first spring, drives the insertion rod to abut against the wheel hub of the tire body. By controlling the rotation shaft in the dynamic balancing machine to rotate, the rotation shaft drives the turntable seat to rotate through the rotating shaft sleeve and the movable rod, so that the insertion rod can rotate to correspond to the wheel hole position of the tire body. The first spring uses its own elastic force to drive the insertion rod to insert into the inner side of the wheel hole of the tire body, thereby realizing the rapid positioning of the tire body.

[0018] 2. In this utility model, after the tire body inspection is completed, the tire body is still in a high-speed rotation state. By controlling the extension end of the second hydraulic cylinder to extend, the extension end of the second hydraulic cylinder drives the brake roller to contact the tire body through the bracket. The brake roller rotates around the bracket under the drive of the tire body. The brake roller rubs against the tire body under the elastic support of the torsion spring, thereby quickly braking the tire body and shortening the tire body inspection cycle.

[0027] like Figures 1 to 5 As shown, an embodiment of this utility model provides a rapid positioning device for a tire dynamic balancing machine, including a fixed plate 1. A pair of first hydraulic cylinders 2 are symmetrically fixed on the fixed plate 1. A fixed frame 3 is fixedly installed on the telescopic end of each hydraulic cylinder. A movable rod 4 is rotatably installed on the fixed frame 3. A rotating shaft sleeve 5 is slidably installed on each movable rod 4. A positioning mechanism is provided on the movable rod 4. The positioning mechanism includes a turntable seat 6 fixedly installed on the movable rod 4. A plurality of first circular sleeves 7 are fixedly installed on the turntable seat 6. A first spring 8 is connected to the inner wall of each first circular sleeve 7. The end of the first spring 8 is connected to an insertion rod 9 that is slidably connected to the first circular sleeve 7. A support mechanism is provided on each fixed frame 3. The support mechanism includes a pair of side frames 10 symmetrically fixed on the fixed frame 3. An abutment component is provided on each side frame 10. A ring plate 14 is provided on each of the abutment components. A washer ring 15 is fixedly installed on the ring plate 14. A drive component is provided between the fixing frame 3 and the ring plate 14. The abutment component includes a second round sleeve 11 fixedly installed on the side frame 10. The abutment component also includes a second spring 12 connected to the inner wall of the second round sleeve 11. The end of the second spring 12 is connected to a telescopic block 13 that is slidably connected to the second round sleeve 11. Every two telescopic blocks 13 are fixed together with the ring plate 14. The drive component includes a drive motor 17 fixedly installed on the fixing frame 3. A lead screw 18 is fixedly installed on the output end of the drive motor 17. A threaded block 16 adapted to the lead screw 18 is fixedly installed on the ring plate 14. A pair of turntable seats 6 and a pair of washer rings 15 jointly clamp the tire body 23. Multiple insert rods 9 are located inside the wheel hole of the tire body 23.

[0028] In this embodiment of the invention, the fixed frame 3 and the movable rod 4 are rotatably connected by bearings. The rotating shaft sleeve 5 is connected to the rotating shaft of the dynamic balancing machine. The operator moves the tire body 23 between a pair of pad rings 15 by controlling the handling equipment. By controlling the extension end of the first hydraulic cylinder 2 to extend, the fixed frame 3 drives the pad rings 15 to clamp the tire body 23 through the side frame 10, the second round sleeve 11, the second spring 12, the telescopic block 13, and the ring plate 14. At the same time, the turntable seat 6 drives the insertion rod 9 to abut against the hub of the tire body 23 through the first round sleeve 7 and the first spring 8. By controlling the rotating shaft in the dynamic balancing machine to rotate, the rotating shaft drives the turntable seat through the rotating shaft sleeve 5 and the movable rod 4. 6. Rotate the insert rod 9 so that it corresponds to the wheel hole position of the tire body 23. The first spring 8 uses its own elastic force to drive the insert rod 9 into the inner side of the wheel hole of the tire body 23, thereby realizing the rapid positioning of the tire body 23. Control the drive motor 17 to run, so that the output end of the drive motor 17 can drive the lead screw 18 to rotate. The lead screw 18 interacts with the threaded block 16, and the threaded block 16 drives the washer 15 to move through the ring plate 14, so that the washer 15 separates from the tire body 23. Control the rotation shaft of the dynamic balancing machine to rotate, thereby driving the tire body 23 to rotate for inspection.

[0029] After the test is completed, control the drive motor 17 to reverse so that the washer ring 15 can clamp the tire body 23 again. Control the extension end of the first hydraulic cylinder 2 to retract to the fixed end so that the insert rod 9, turntable seat 6 and washer ring 15 can be separated from the tire body 23.

[0030] Figures 1 to 5 As shown, a pair of braking mechanisms are symmetrically arranged on the fixed plate 1. Each braking mechanism includes a second hydraulic cylinder 19 fixedly mounted on the fixed plate 1. A bracket 20 is fixedly installed on the telescopic end of the second hydraulic cylinder 19. A braking assembly is provided on the bracket 20. The braking assembly includes a brake roller 21 rotatably mounted on the bracket 20. Two torsion springs 22 are connected between the bracket 20 and the brake roller 21.

[0031] In this embodiment of the present invention, after the tire body 23 is inspected, the tire body 23 is still in a high-speed rotation state. By controlling the extension end of the second hydraulic cylinder 19 to extend, the extension end of the second hydraulic cylinder 19 drives the brake roller 21 to contact the tire body 23 through the bracket 20. The brake roller 21 rotates around the bracket 20 under the drive of the tire body 23. The brake roller 21 rubs against the tire body 23 under the elastic support of the torsion spring 22, thereby enabling the tire body 23 to be braked quickly and shortening the inspection cycle of the tire body 23.

[0032] Working principle: The operator moves the tire body 23 between a pair of pad rings 15 using the handling equipment. By controlling the extension end of the first hydraulic cylinder 2, the fixing frame 3, through the side frame 10, the second sleeve 11, the second spring 12, the telescopic block 13, and the ring plate 14, drives the pad rings 15 to clamp the tire body 23. At the same time, the turntable seat 6, through the first sleeve 7 and the first spring 8, drives the insertion rod 9 to abut against the hub of the tire body 23. By controlling the rotation shaft in the dynamic balancing machine to rotate, the rotation shaft drives the turntable seat 6 to rotate through the rotating shaft sleeve 5 and the movable rod 4, allowing the insertion rod 9 to rotate to a position where it is aligned with the hub of the tire body 23. The wheel hole position of the tire body 23 corresponds to the first spring 8, which uses its own elastic force to drive the insert rod 9 into the inner side of the wheel hole of the tire body 23 for rapid positioning of the tire body 23. The drive motor 17 is controlled to run, so that the output end of the drive motor 17 rotates to drive the lead screw 18 to rotate. The lead screw 18 interacts with the threaded block 16, and the threaded block 16 drives the washer ring 15 to move through the ring plate 14, so that the washer ring 15 separates from the tire body 23. The rotation shaft of the dynamic balancing machine is controlled to rotate, so that the tire body 23 rotates and is inspected.

[0033] After the tire body 23 is inspected, the tire body 23 is still rotating at high speed. By controlling the extension end of the second hydraulic cylinder 19 to extend, the extension end of the second hydraulic cylinder 19 drives the brake roller 21 to contact the tire body 23 through the bracket 20. The brake roller 21 rotates around the bracket 20 under the drive of the tire body 23. The brake roller 21 rubs against the tire body 23 under the elastic support of the torsion spring 22, and quickly brakes the tire body 23.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
