[0026] The following specific embodiments illustrate the implementation mode of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiments, this does not mean that the features of this invention are limited to this implementation mode. On the contrary, the purpose of introducing the invention in conjunction with the implementation mode is to cover other alternatives or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, many specific details will be included in the following description. The present invention can also be implemented without these details. In addition, in order to avoid confusion or obscuring the key points of the present invention, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0027] See Figures 1-4 , an assembly tool for an open retaining ring, including a connected pusher 1 and a fitting 2. An arc-shaped positioning part 3 adapted to the open retaining ring is provided at the end of the fitting 2. A positioning groove 5 is provided on the concave surface of the arc-shaped positioning part 3. A positioning and attracting part 4 is also provided on one side of the end of the fitting 2 where the arc-shaped positioning part 3 is not provided. The open retaining ring (GBT896 - 19) is placed on the positioning groove 5, and three-dimensional positioning in the X, Y, and Z directions is achieved under the cooperative action of the positioning groove 5 and the positioning and attracting part 4. The arc-shaped positioning part 3 and the positioning and attracting part 4 are respectively arranged on two sides of the fitting 2. The positioning in the X and Y directions of the open retaining ring is achieved through the arc-shaped positioning part 3 and the positioning groove 5, and the positioning in the Z direction of the open retaining ring is achieved through the positioning and attracting part 4. The arc-shaped positioning part 3 is arranged with a variable diameter to achieve the assembly of the open retaining ring (GBT896 - 19). The arc-shaped positioning part 3 includes a first arc-shaped positioning part 6 and a second arc-shaped positioning part 7. A gap is provided between the first arc-shaped positioning part 6 and the second arc-shaped positioning part 7. The fitting 2 includes a first assembly arm 8 and a second assembly arm 9. The first arc-shaped positioning part 6 and the second arc-shaped positioning part 7 are respectively connected to the first assembly arm 8 and the second assembly arm 9.

[0028] When assembling the snap ring (GBT896-19) using this snap ring assembly tooling, place the snap ring (GBT896-19) on the positioning groove 5, then align the snap ring (GBT896-19) with the snap ring assembly groove on the main clutch tensioner pulley. Subsequently, manually push the pusher 1 so that the snap ring acts on the tensioner pulley. The tensioner pulley exerts a reaction force on the snap ring, causing the snap ring, the first arc-shaped positioning member 6, and the second arc-shaped positioning member 7 to open to both sides. The snap ring is then precisely installed into the snap ring assembly groove. Remove the assembly tooling. If the main clutch tensioner pulley can rotate flexibly and the snap ring (GBT896-19) does not come out, the snap ring assembly is successful.

[0029] The gap between the first arc-shaped positioning member 6 and the second arc-shaped positioning member 7 is 0.3 - 0.8 mm, preferably 0.5 mm, to facilitate the positioning and assembly of the snap ring. While preventing the snap ring from deforming, it also improves the fixation of the snap ring. If the gap is too small, when pushing the pusher 1, the opening degree of the first arc-shaped positioning member 6 and the second arc-shaped positioning member 7 is insufficient to complete the assembly of the snap ring. If the gap is too large, it is difficult to position, and the snap ring is prone to deformation.

[0030] The positioning attracting member 4 is a positioning magnet. When assembling the snap ring, it performs Z-direction positioning through the suction force of the strong magnetic magnet. The positioning attracting member 4 is arranged at the junction of the first assembly arm 8 and the second assembly arm 9, that is, spaced from the center position of the snap ring to ensure the positioning accuracy.

[0031] The pusher 1 includes a chassis 10 and a boss 11. The boss 11 is connected to the fitting 2 through a bolt 12. A screw hole 13 adapted to the bolt 12 is provided at one end of the fitting 2 away from the arc-shaped positioning member 3; the chassis 10 is circular, facilitating the operation of the staff.

[0032] The snap ring assembly tooling provided by the present utility model is used for the assembly of the snap ring (GBT896-19). Through the setting of the positioning groove 5 and the positioning attracting member 4, precise positioning of the snap ring is achieved; the arc-shaped positioning member 3 is set to be variable in diameter, which can realize the expansion of the snap ring, facilitating the assembly of the snap ring, and the operation is simple and labor-saving; moreover, the snap ring does not need to be struck during the assembly process, will not deform, ensuring the assembly quality and efficiency, and at the same time eliminating the safety hazards brought by hammering assembly.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
