Description

Technical Field

[0001] The utility model relates to a steering wheel disassembly tool, belonging to the field of vehicle manufacturing. Background Art

[0002] The steering wheel is assembled on the steering column through an assembly hole at the center, and the outer wall surface of the steering column and the hole wall of the assembly hole of the steering wheel are both conical, and the two are assembled together through interference fit of the conical assembly surfaces, and the steering column is inserted into the assembly hole of the steering wheel and the upper end extends out of the steering wheel. The upper end of the steering column is formed with a thread. After the two are assembled, a fixing nut is installed on the upper end of the steering column. The fixing nut applies a large pressure on the steering wheel, thereby increasing the interference fit between the two, making the two assemble tighter and ensuring that the steering wheel is firmly installed. When the steering wheel needs to be repaired or replaced, the steering wheel needs to be removed from the steering column. In the prior art, the fixing nut is usually separated from the top of the steering wheel by first hitting the nut with a hammer. After the fixing nut is loosened, the fixing nut is removed using a wrench or other tool. However, the fixing nut of each automobile steering wheel is of different sizes, and it is necessary to prepare wrenches of various specifications. In addition, the gap between the steering wheel and the fixing nut is small and it is not convenient for tools such as wrenches to move. When the wrench cannot move, it is necessary to loosen the wrench, and then clamp the fixing nut in the direction where it can move and then rotate it. The fixing nut is separated from the steering wheel repeatedly in this way. Therefore, it is necessary to design a steering wheel removal tool that can adapt to various fixing nut sizes. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a steering wheel disassembly tool to solve the problems raised in the above-mentioned background technology. The utility model can adapt to the sizes of fixing nuts of different specifications and is convenient for reducing the operating space by rotating the fixing nuts when disassembling them.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a steering wheel disassembly tool, comprising a fixed base, a connecting rod is installed on the top of the fixed base, an operating rod is fixedly installed on the top of the connecting rod, a protective sleeve is provided on the outside of the operating rod, three screws are evenly installed on the fixed base, an adjustment handle is installed on the end of the screw located on the outside of the fixed base, a clamping plate is installed on the end of the adjustment handle located inside the fixed base, a gasket is installed on the bottom of the clamping plate, an insertion base is installed on the top of the clamping plate, and the end of the screw away from the adjustment handle is inserted in the insertion base.

[0005] Furthermore, three limiting bases are evenly installed on the outer side of the fixed base, and through holes are formed on the limiting bases, and the screw rods are inserted into the through holes.

[0006] Furthermore, three screw holes are evenly opened on the fixed base, the limiting base is installed on the outside of the screw hole, the through hole is connected to the screw hole, and a screw rod is installed in the inner thread of the screw hole.

[0007] Furthermore, a fixing plate is installed at the bottom of the clamping plate, a gasket is connected and fixed to the bottom of the fixing plate, a connecting hole is opened on the fixing plate, positioning grooves are symmetrically opened on both sides of the clamping plate, and circular holes are symmetrically formed on both sides of the clamping plate, and the positioning grooves are connected to the circular holes.

[0008] Furthermore, a fixing plate is installed in the positioning groove, a limiting rod is installed at the other end of the fixing plate, the limiting rod passes through the circular hole and the connecting hole, and the limiting rod installs the fixing plate on the clamping plate.

[0009] Furthermore, a bearing is installed on the inner side of the insertion base, and a screw is installed on the inner side of the bearing.

[0010] The beneficial effects of the utility model: the utility model provides a steering wheel disassembly tool. When the fixing nut on the steering wheel needs to be removed, the fixing base is sleeved over the fixing nut, and then the adjusting handle is rotated to drive the screw to move toward the inside of the fixing base so that the gasket fits the surface of the fixing nut. The operation of the other two screws is the same as above to lock the fixing nut and the fixed base. After the adjustment is completed, the operating lever is rotated to make the fixed base drive the fixing nut to rotate. Through the cooperation of the screw and the gasket, it is easy to adapt to fixing nuts of different sizes.

[0011] Three screws are evenly distributed on the periphery of the fixed base near the steering wheel. The top of the connecting rod installed above the fixed base is fixedly connected to the operating rod. The operating rod of the tool for rotating the fixing nut is directly above the steering wheel. The operating space between the steering wheel and the fixing nut does not affect the operating rod, which facilitates the rotation direction of the operating rod when removing the fixing nut, thereby improving the removal efficiency of the fixing nut.

[0012] The limiting rod passes through the connecting hole and the round hole, and the gasket is installed at the bottom of the clamping plate, which is convenient for disassembly and replacement when the gasket is damaged. The fixing plate is installed inside the positioning groove to prevent the fixing plate from being exposed to the cross groove on the outer surface for a long time and causing wear and difficulty in disassembly during replacement. The end of the screw away from the adjusting handle is inserted in the bearing, which is convenient for keeping the position of the gasket from moving when the screw is turned to clamp the fixing nut, so that the gasket is always in close contact with the outer surface of the fixing nut.
