[0016] Please see Figure 1-8 A tool for replacing engine transfer case bushings includes an elastic compression disc 1, a bushing positioning and mounting disc 2, a disassembly and positioning bracket 3, a base mounting and positioning disc 4, a disassembly and positioning chuck 6, and a disassembly and positioning screw 7.

[0017] Specifically, the mounting assembly consists of the rubber sleeve positioning plate 2, the base mounting positioning plate 4, and the disassembly and assembly positioning screw 7. Among them: Multiple limiting blocks 201 are fixedly installed on the rubber sleeve positioning mounting plate 2 by screws. The middle part of the rubber sleeve positioning mounting plate 2 has a mounting plate waist-shaped hole 202, and the multiple limiting blocks 201 correspond one-to-one with the limiting groove structure on the rubber sleeve.

[0018] The base mounting positioning plate 4 has a positioning plate contact structure 401 on its edge that mates with the corresponding side of the rubber sleeve base structure. A positioning plate threaded hole 402, which mates with the disassembly and assembly positioning screw 7, is located in the center of the plate. Four positioning holes 403 are formed around the positioning plate threaded hole 402. By inserting screws or pins into the holes on the rubber sleeve body along the positioning holes 403, the rubber sleeve can be positioned, preventing rotation when it is pressed into the base.

[0019] When installing the rubber sleeve, the limiting block 201 in the rubber sleeve positioning mounting plate 2 is inserted into the limiting groove on the rubber sleeve, the rubber sleeve is aligned with the installation position of the rubber sleeve base, and the base mounting positioning plate 4 is fitted onto the rubber sleeve base on the other side. The disassembly and assembly positioning screw 7 passes through the oblong hole on the rubber sleeve positioning mounting plate 2, the rubber sleeve, the rubber sleeve base and the base mounting positioning plate 4, and is threadedly connected to the base mounting positioning plate 4 to limit the position of each component. Both ends of the disassembly and assembly positioning screw 7 are equipped with matching nuts 9 for positioning, and a plane bearing 8 is also provided on the side of the rubber sleeve positioning mounting plate 2.

[0020] The nut 9 on the side of the rotating rubber sleeve positioning mounting plate 2 presses the rubber sleeve into the rubber sleeve base through the plane bearing 8 and the positioning mounting plate 2.

[0021] Specifically, the disassembly assembly consists of the disassembly positioning bracket 3, the disassembly positioning chuck 6, and the disassembly positioning screw 7. Among them: The disassembly positioning bracket 3 includes a bracket base plate 301. The bracket base plate 301 is provided with two support structures 302 and two positioning rods 304. The support structure 302 is a columnar structure. The bracket base plate 301 has a bracket base plate threaded hole 303 in the middle. The positioning rod 304 is a columnar structure that is inserted into the hole of the rubber sleeve body to prevent the rubber sleeve from rotating during disassembly.

[0022] The edge of the disassembly positioning chuck 6 is provided with a chuck contact structure 601 that contacts the corresponding side rubber sleeve, and a chuck waist-shaped hole 602 is provided in the center to facilitate the disassembly and assembly of the positioning screw 7.

[0023] When disassembling the rubber sleeve, the support structure 302 on the disassembly positioning bracket 3 is brought into contact with the structural surface of one side of the rubber sleeve base (the side where the rubber sleeve is removed). Then, the disassembly positioning chuck 6 is clamped on one side of the rubber sleeve (the opposite side where the rubber sleeve is removed). The disassembly positioning screw 7 passes through the disassembly positioning bracket 3, the rubber sleeve, the rubber sleeve base and the disassembly positioning chuck 6, and is threadedly connected to the disassembly positioning bracket 3. Both ends of the disassembly positioning screw 7 are equipped with matching nuts 9 for positioning, and a plane bearing 8 is also provided on the side of the disassembly positioning bracket 3.

[0024] After tightening the nuts 9 on both sides, rotate the end of the disassembly and assembly positioning screw 7 located on the side of the disassembly and assembly positioning bracket 3, move the disassembly and assembly positioning screw 7 outward, drive the disassembly and assembly positioning chuck 6 to move, and pull out the rubber sleeve.

[0025] Specifically, in this embodiment, an elastic compression disc 1 is also provided. The elastic compression disc 1 is a split structure, which includes two opposing semi-circular ring structures 101. The two semi-circular ring structures are positioned by positioning pins 102 and fastened together by fastening screws 103, forming a space for placing the rubber sleeve between them.

[0026] For rubber sleeves with high elasticity, they cannot be directly inserted into the mounting holes of the rubber sleeve base. In this case, the rubber sleeve is placed in the space between the two semi-circular ring structures 101, and the rubber sleeve is first compressed by rotating the fastening screw 103, and then inserted into the mounting holes of the rubber sleeve base, and then installed by the mounting components.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
