Description

Technical Field

[0001] This utility model relates to the field of clutch snap ring press-fit technology, specifically a clutch snap ring press-fit auxiliary tool. Background Technology

[0002] With the rapid development of the automotive industry, the clutch, as a key component of the automotive transmission system, has its assembly process precision and efficiency crucial to overall vehicle performance and production efficiency. This is especially true in the clutch circlip pressing stage, which directly impacts the clutch assembly quality, reliability, and production efficiency. The circlip pressing process plays a vital role in clutch assembly; however, current operational methods still present certain problems and challenges.

[0003] Currently, there are three main types of snap ring pressing solutions commonly used in the industry. The first method involves using simple manual pressing tools, such as pry bars or pliers, to manually press one end of the snap ring into the mounting groove. This method requires skilled operators; unskilled workers are prone to problems such as snap ring misalignment, uneven pressing, or even product damage due to improper operation. Furthermore, manual operation is inefficient and has poor quality consistency, making it difficult to meet the demands of high-efficiency and high-precision production.

[0004] The second approach employs a complex positioning and pressing structure. This method uses a dedicated snap ring pressing platform to fix the clutch and guides the snap ring during pressing with guide components. While this structure reduces operational difficulty and improves assembly accuracy to some extent, it is more complex, has higher manufacturing costs, and is inconvenient for subsequent maintenance. Each assembly requires the clutch to be installed in a specific position, making the process cumbersome and inefficient. Especially in mass production, this method may not meet the requirements for rapid assembly.

[0005] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a clutch snap ring press-fitting auxiliary tool. Utility Model Content

[0006] The purpose of this utility model is to provide a clutch retaining ring press-fitting auxiliary tool to solve the problems mentioned in the background art.

[0013] The handle has two ends connected to handle connecting posts;

[0014] The side wall of the press-fit sleeve has a limit block slot to avoid the limit block of the positioning guide sleeve.

[0026] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a clutch retaining ring press-fitting auxiliary tool: it includes a positioning guide sleeve 1, the inner side of which is provided with at least one limiting block 2, used to limit the radial movement of the retaining ring during the press-fitting process. The lower end of the positioning guide sleeve 1 is provided with four circumferentially distributed square protrusions, which are used to position with the clutch housing to ensure that the press-fitting sleeve 4 can be accurately aligned with the installation position.

[0028] A press-fit sleeve 4 is coaxially fitted above the positioning guide sleeve 1. The upper end face of the press-fit sleeve 4 has three equally divided pin holes 42 for engaging with three stepped pins 3. The stepped pins 3 are fixed to the upper end face of the positioning guide sleeve 1 and are evenly distributed on three sides, forming a clearance fit with the pin holes 42 of the press-fit sleeve 4 to ensure the axial positioning of the retaining ring during the press-fitting process.

[0029] Two handle connecting posts 5 are symmetrically fixed to the upper end face of the press-fit sleeve 4 for mounting handles 6. Both ends of the handle 6 are connected to the handle connecting posts 5 respectively, so that the operator can apply force through the handle 6 to press-fit the retaining ring.

[0030] A limiting block slot 41 is provided on the side wall of the press sleeve 4 to avoid the limiting block 2 of the positioning guide sleeve 1, so as to ensure that the limiting block 2 will not hinder the smooth pressing of the snap ring during the press-fitting process.

[0031] To further improve positioning accuracy, the square protrusion at the lower end of the positioning guide sleeve 1 matches the groove on the end face of the clutch housing to achieve radial positioning. Simultaneously, the inner side of the positioning guide sleeve 1 is provided with a square groove for installing a limiting block 2, which is fixed within the groove by bolts.

[0032] To provide better guidance, the inner diameter of the positioning guide sleeve 1 gradually decreases from top to bottom, forming a guide cone surface, which helps the snap ring to smoothly enter the installation position.

[0033] The lower end of the handle connecting post 5 is fixed to the threaded hole on the upper end face of the press sleeve 4 by bolts, and the upper end is connected to the handle 6 by bolts to ensure the stability and durability of the handle 6.

[0034] The bottom inner side of the positioning guide sleeve 1 is provided with a circlip pre-installation groove for initial positioning of the circlip, which facilitates the operator to quickly and accurately pre-install the circlip.

[0035] Through the above structural design, the clutch snap ring pressing auxiliary tool of this utility model can effectively improve the accuracy and stability of snap ring pressing, avoid problems such as positioning deviation and uneven pressing caused by manual operation, and improve the assembly quality and reliability of the product. At the same time, the auxiliary tool has a relatively simple structure, low manufacturing cost, and is easy to maintain and operate, greatly improving production efficiency, especially suitable for mass production scenarios. The handle design makes operation more convenient and labor-saving, further improving work efficiency.
