DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Reference Figures 1-5 A rubber bushing assembly tool, comprising a bushing 1 and two mouth opening mechanisms 2, the mouth opening mechanism 2 comprises a positioning ring 3, one side of the positioning ring 3 movably abuts one end of the bushing 1, a plurality of rotating claws 4 are rotatably installed on one side of the positioning ring 3 through a hinge 8, the plurality of rotating claws 4 are arranged at equal intervals in a circle, the rotating claw 4 comprises a long inclined section 5, a short inclined section 6 and a hook ring section 7, the long inclined section 5 is used for being inserted into the bushing 1 and being swung through the hinge 8 as a rotating point to open the bushing 1, and the short inclined section 6 and the hook ring section 7 are used for extracting the mouth opening mechanism 2 after the bushing 1 is opened.

[0024] In the embodiment, the bottom end of the long inclined section 5 is conically arranged, and the two sides of the long inclined section 5 are provided with a flange structure, the conical arrangement of the bottom end of the rotating claw 4 facilitates that the plurality of rotating claws 4 can be synchronously accommodated in the bushing 1, as shown in the drawings, the bottoms of the plurality of rotating claws 4 abut each other, and the flange structure reduces the friction between the edge of the rotating claw 4 and the bushing 1, protects the bushing 1, and facilitates subsequent extraction of the mouth opening mechanism 2.

[0025] In the embodiment, a plurality of inner clamping plates 9 are fixedly installed on the inner wall of the positioning ring 3, the inner clamping plate 9 is arranged in a right angle, and the plurality of inner clamping plates 9 on the same side are used for fixing one end of the bushing 1, through the arrangement of the plurality of inner clamping plates 9, the bushing 1 can be initially sleeved on the positioning ring 3, and the subsequent rotating claw 4 can facilitate opening of the bushing 1.

[0026] In the embodiment, a lightweight hole one 10 is formed in one side of the rotating claw 4, and a plurality of lightweight hole twos 11 are formed in one side of the positioning ring 3, the plurality of lightweight hole twos 11 on the same side are arranged at equal intervals in a circle, the functions of the lightweight hole one 10 and the lightweight hole two 11 are both to reduce the weight of the whole tool, facilitate manual operation of workers, and the lightweight hole one 10 reduces the contact area between the rotating claw 4 and the inner wall of the bushing 1, facilitating extraction of the mouth opening mechanism 2 from the bushing 1.

[0027] In this embodiment, an auxiliary rod 12 is also included. The auxiliary rod 12 is used to insert into the bushing 1 and open one end of the bushing 1. By opening both ends of the bushing 1 with the auxiliary rod 12 and the shaft respectively, the force required for the shaft to be inserted is reduced, making the assembly process easier and avoiding tearing or deformation of the bushing 1 that may be caused by forced insertion.

[0028] It should be noted that if the auxiliary rod 12 is not set to open the bushing 1 synchronously with the shaft, opening only one end will result in uneven stress distribution inside the bushing 1. During the insertion of the shaft, the unopened end may bear greater local pressure, increasing the risk of the bushing 1 tearing or deforming. Furthermore, since the other end is still tight, the shaft needs greater force and more precise operation to be inserted, which may result in it not being able to pass through the bushing 1 smoothly.

[0029] In this embodiment, a handle ring 13 is fixedly installed on one side of the auxiliary rod 12. An internal groove 14 is opened at one end of the auxiliary rod 12, and an annular groove is opened on one side of the auxiliary rod 12. A magnet ring 15 is provided in the annular groove. Some metal parts or shafts usually have connecting shafts or protrusions with smaller diameters at both ends. The internal groove 14 is used to accommodate this part of the structure, so that the magnet ring 15 can fit against one side of the shaft and be tightly attracted.

[0030] The working principle of this utility model is as follows: Two support mechanisms 2 are described in the attached diagram. Figure 1 As shown, the auxiliary rod 12 is inserted into one end of the bushing 1 through the lower support mechanism 2. The edge of one end of the auxiliary rod 12 abuts against the inclined surface of the rotating claw 4, thereby causing the rotating claw 4 to swing downward with the hinge 8 as the rotation point until the long inclined section 5 of the rotating claw 4 is flush with the outer wall of the auxiliary rod 12, thereby opening one end of the bushing 1 and pushing the auxiliary rod 12 further into the bushing 1 until it approaches the upper support mechanism 2.

[0031] While the auxiliary rod 12 is inserted into the support mechanism 2, the shaft is inserted into the bushing 1 through the upper support mechanism 2. The bushing 1 is also opened at one end by the auxiliary rod 12. The shaft is pushed closer to the auxiliary rod 12 so that it is magnetically attracted to the auxiliary rod 12. Finally, the auxiliary rod 12 is pulled out of the bushing 1 by pulling the handle ring 13 on one side, and the shaft is inserted into the bushing 1 on the other side, so that the bushing 1 is fitted on the outside of the shaft. After the bushing 1 is fitted, the hook ring section on the claw 4 is rotated to facilitate the worker to pull out the support mechanism 2.

[0032] The preferred embodiments disclosed above are only used to help describe the utility model. The preferred embodiments do not describe all the details and do not limit the utility model to the specific embodiments. Obviously, according to the content of the specification, many modifications and changes can be made. The specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that the persons skilled in the art can well understand and utilize the utility model.
