Description

Technical Field

[0001] This utility model relates to the field of automotive disassembly tools, specifically a tooling for disassembling automotive steering wheels. Background Technology

[0002] In the field of automotive repair and disassembly, the removal of car steering wheels is a relatively common operation. Car steering wheels are usually installed on the central support column through a spline fit, which is a relatively stable connection method.

[0003] There are several obvious problems with the traditional disassembly process of car steering wheels. On the one hand, due to the lack of precise positioning and a disassembly structure that distributes force evenly, it is difficult to operate along the axis of the central support column during disassembly, which can easily damage the splined parts. On the other hand, traditional disassembly tools often cannot apply even tension to the steering wheel, resulting in uneven force distribution during disassembly. This can damage the steering wheel itself and related components. These problems not only affect the efficiency of disassembling the car steering wheel, but may also increase repair costs due to component damage, and even affect the overall performance and safety of the car.

[0004] Therefore, it is necessary to propose a tooling for disassembling automobile steering wheels. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a car steering wheel disassembly fixture, which has the advantages of being able to precisely disassemble along the axis of the central bearing column and apply tension evenly, thus solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a tooling for disassembling an automobile steering wheel, including a main rod:

[0007] The lower end of the main rod is provided with a mating groove, and the upper end of the main rod is provided with a sleeve groove.

[0008] A connector is inserted into the inside of the docking groove. An adjusting screw is movably fitted inside the first sleeve groove. A lifting block is threadedly connected to the outer surface of the adjusting screw. Grooves are provided on all four sides of the lifting block. A rotating block is rotatably connected to the inside of the groove via a connecting shaft. A sleeve is fixedly connected to the middle of the lower surface of the rotating block. An internal thread groove is provided inside the sleeve. An extension rod is threadedly connected to the internal thread groove. A second sleeve groove is provided at the lower end of the extension rod. A hook is rotatably fitted inside the second sleeve groove.

[0009] Preferably, a through slot is provided at the overlap of the mating groove and the connector, and a plug rod is inserted into the slot, with an elastic ring elastically sleeved on the outer surface of the end of the plug rod.

[0010] Preferably, a bearing block is fixedly connected to the outer surface of the main rod, and a limit rod is fixedly connected to each of the four corners of the upper surface of the bearing block. A circular groove is opened at each of the four corners of the lifting block, and the interior of the circular groove is movably connected to the outer surface of the limit rod.

[0011] Preferably, a handle is fixedly connected to the upper end of the adjusting screw.

[0012] Preferably, the inner wall of the second socket is provided with a wear-resistant coating, and the wear-resistant coating is made of molybdenum disulfide material.

[0013] Preferably, the hook opening is provided with anti-slip serrations.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This type of automotive steering wheel disassembly fixture, when disassembling a steering wheel with a splined fit on a center support column, involves selecting a suitable connector and installing it into a slot at the lower end of the main rod. By installing the connector into the center support column interface, the position of the extension rod inside the sleeve is adjusted so that the hooks at the lower end of the extension rod can be equidistantly hooked at four points on the steering wheel. Rotating the adjusting screw connected to the upper end of the main rod drives the lifting block of the support hook upwards, thereby pulling the steering wheel away from the center support column and completing the disassembly. This structure effectively disassembles the steering wheel along the axis of the center support column, avoiding damage to the splined fit. Simultaneously, the equidistant hook structure applies even tension to the steering wheel. Combined with the precise positioning of the center support column, this ensures uniform force on the steering wheel during disassembly, preventing damage. This achieves efficient and safe disassembly of the automotive steering wheel, improving disassembly efficiency while ensuring that the steering wheel and related components are not damaged during the disassembly process.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A tooling for disassembling an automobile steering wheel, comprising a main rod 1:

[0031] The lower end of the main rod 1 is provided with a mating groove 120, and the upper end of the main rod 1 is provided with a sleeve groove 110.

[0032] A connector 2 is inserted into the inside of the docking groove 120. An adjusting screw 3 is movably sleeved inside the first sleeve groove 110. A lifting block 4 is threadedly connected to the outer surface of the adjusting screw 3. Grooves 410 are provided on all four sides of the lifting block 4. A rotating block 420 is rotatably connected to the inside of the groove 410 via a connecting shaft. A sleeve 430 is fixedly connected to the middle position of the lower surface of the rotating block 420. An internal thread groove 431 is provided inside the sleeve 430. An extension rod 440 is threadedly connected to the inside of the internal thread groove 431. A second sleeve groove 441 is provided at the lower end of the extension rod 440. A hook 450 is rotatably sleeved inside the second sleeve groove 441. A through slot 6 is provided at the overlap of the docking groove 120 and the connector 2. A plug rod 610 is inserted into the slot 6. An elastic ring 620 is elastically sleeved on the outer surface of the end of the plug rod 610. A handle 310 is fixedly connected to the upper end of the adjusting screw 3.

[0033] By inserting the connector 2 into the mating groove 120, and then using the plug rod 610 to pass through the slot 6, the elastic ring 620 can provide a certain elastic force to ensure that the plug rod 610 is firmly inserted, thereby realizing a reliable connection between the main rod 1 and the connector 2. The adjusting screw 3 is movably sleeved inside the sleeve groove 110. The upper end of the adjusting screw 3 is fixedly connected to the handle 310, which makes it convenient for the operator to rotate the adjusting screw 3.

[0034] According to the size and structure of the steering wheel, the operator can adjust the extension length of the extension rod 440 inside the sleeve 430 by rotating the extension rod 440, thereby adjusting the position of the hook 450 so that the hook 450 can be accurately hooked into the appropriate position of the steering wheel. At the same time, the rotating block 420 can rotate in the groove 410 so that the hook 450 can adapt to the hooking requirements of different angles.

[0035] As a preferred technical solution of this utility model, a bearing block 5 is fixedly connected to the outer surface of the main rod 1, and a limit rod 510 is fixedly connected to the four corners of the upper surface of the bearing block 5. A circular groove 460 is opened at the four corners of the lifting block 4, and the interior of the circular groove 460 is movably connected to the outer surface of the limit rod 510.

[0036] This structural design allows the limiting rod 510 to limit and guide the lifting block 4 as it moves up or down under the drive of the adjusting screw 3, ensuring that the lifting block 4 moves smoothly along the axis of the main rod 1 and avoiding deviation.

[0037] As a preferred technical solution of this utility model, the inner wall of the second sleeve groove 441 is provided with a wear-resistant coating, and the wear-resistant coating is made of molybdenum disulfide material, which can reduce the friction when the hook 450 rotates and improve the service life of the component.

[0038] As a preferred technical solution of this utility model, the hook 450 is provided with anti-slip teeth at the hook opening, which can increase the friction between the hook 450 and the steering wheel and prevent the hook 450 from slipping off the steering wheel during disassembly.

[0039] Working principle: When it is necessary to disassemble the steering wheel that is splined to the center support column, firstly, select the appropriate connector 2 according to the shape and size of the interface end of the center support column, insert the connector 2 into the mating groove 120 at the lower end of the main rod 1, and then insert the plug rod 610 through the slot 6. Using the elastic effect of the elastic ring 620, the connector 2 is firmly fixed to the main rod 1. Then, install the connector 2 to the interface end of the center support column to achieve the initial docking of the tooling with the car steering wheel system.

[0040] Afterwards, the operator adjusts the position of the extension rod 440 inside the sleeve 430 according to the specific situation of the steering wheel. By rotating the extension rod 440, it moves in the internal thread groove 431 of the sleeve 430, thereby changing the extension length of the extension rod 440, and then adjusting the position of the hook 450 so that the hook 450 at the lower end of the extension rod 440 can be equidistantly hooked on the four points of the steering wheel. Since the rotating block 420 can rotate in the groove 410, the hook 450 can flexibly adjust its angle to adapt to the shape of the steering wheel, ensuring that the four hooks 450 are evenly hooked on the steering wheel.

[0041] After the position adjustment of hook 450 is completed, the operator turns the handle 310 at the upper end of the main rod 1, which drives the adjusting screw 3 to rotate. Since the adjusting screw 3 is threadedly connected to the lifting block 4 and the lifting block 4 is limited by the limiting rod 510, the rotation of the adjusting screw 3 will drive the lifting block 4 to move upward along the limiting rod 510. When the lifting block 4 moves upward, it drives hook 450 to pull the steering wheel upward through the rotating block 420, sleeve 430 and extension rod 440.

[0042] During this process, the four hooks are equidistant at 45° intervals, which can evenly apply an upward pulling force to the steering wheel. Simultaneously, the connection between connector 2 and the interface end of the central support column ensures that the tooling applies pulling force along the axis of the central support column. This design ensures that the steering wheel is subjected to uniform force during disassembly and is pulled smoothly along the axis of the central support column, avoiding damage to the splined mating parts due to uneven force or deviation of the pulling direction from the axis. Finally, the steering wheel detaches from the central support column under the pulling force, completing the disassembly operation.
