Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] like Figure 1-4As shown, a snap ring assembly device that prevents snap ring deformation includes a mounting frame, on which a positioning component and a pressure head component are provided, and the positioning component and the pressure head component are vertically aligned. The positioning component is detachably connected to a part component 4 that needs to be fitted with a snap ring. The pressure head component includes a movable plate 1 and a snap ring pressure head 2. The movable plate 1 is elastically and movably connected to the mounting frame. A snap ring 3 is fitted on the snap ring pressure head 2. One end of the snap ring pressure head 2 is connected to the movable plate 1 through an elastic adjustment component. When the other end of the snap ring pressure head 2 is connected to the part component 4, it continues to elastically compress to fit the snap ring 3 onto the part component 4.
[0015] The snap ring assembly device of this utility model has a simple structure. It positions and installs the snap ring 3 through the pressure head assembly, and then performs elastic compression assembly in the direction of the positioning assembly to achieve the effect of not deforming the snap ring 3. While reducing the scrap of snap ring 3, it significantly improves the product quality and the consistency of snap ring assembly.
[0016] Furthermore, the mounting frame includes a base 5, on which two guide posts 6 are symmetrically arranged. The movable plate 1 is sleeved on the two guide posts 6, and a first elastic element 7 that moves in coordination with the movable plate 1 is also sleeved on the guide posts 6. This design, through the two guide posts 6, improves the smoothness of the movement and rebound of the movable plate 1, thereby improving the assembly efficiency and accuracy of the retaining spring 3. The first elastic element 7 can be a compression spring.
[0017] Furthermore, the positioning component includes a positioning seat 8, one end of which is connected to the base 5, and the other end is detachably connected to the component assembly 4. This design, through the positioning seat 8, improves the installation stability of the component assembly 4 and also better coordinates with the positioning component for assembling the retaining ring 3, thus improving the assembly effect of the retaining ring 3. The positioning seat 8 and the component assembly 4 can be selected for mutual compatibility to ensure connection stability, and the retaining ring pressure head 2 can also be flexibly replaced according to the component assembly 4.
[0018] Furthermore, the elastic adjustment component includes an external pressure head 9, which has a connecting through hole and a second elastic element 10. One end of the connecting through hole is connected to the movable plate 1 via a connector. The external pressure head 9 also has a limiting slide 901, which communicates with the through hole. The snap ring pressure head 2 is connected to the other end of the connecting through hole via a positioning pin 11, and the positioning pin 11 moves within the limiting slide 901. One end of the second elastic element 10 abuts against the snap ring pressure head 2, and the other end is connected to the connector. In the above design, the outer pressure head 9 connects to the retaining spring pressure head 2, and the second elastic element 10 allows the outer pressure head 9 to move along the outer wall of the retaining spring pressure head 2, pressing the retaining spring 3 against the component assembly 4 for retaining spring assembly. The limiting slide 901 limits the compression and rebound positions of the second elastic element 10, preventing excessive compression of the retaining spring 3 and causing its deformation, thereby improving the assembly qualification rate of the retaining spring 3, reducing the scrap rate of the retaining spring, and significantly improving the product quality and the consistency of retaining spring assembly. The second elastic element 10 can be a compression spring, and the connecting part can be a combination of screws and flat washers, which improves the connection stability between the outer pressure head 9 and the movable plate 1 and improves the safety of the device.
[0019] Furthermore, two symmetrically arranged limiting slides 901 are provided, and both ends of the limiting slides 901 are provided with positioning grooves for locking the positioning pins 11. The above design makes the movement and rebound process of the external pressure head 9 more stable, and the positioning effect of the two position points is also better, thereby improving the assembly efficiency and assembly consistency of the snap ring 3.
[0020] Furthermore, at least one limiting post 12 can be detachably installed on the base 5. A guide sleeve 13 is provided at the joint between the movable plate 1 and the guide post 6, with one end of the guide sleeve 13 abutting against the end of the first elastic element 7 and the other end protruding from the movable plate 1. A screw 14 and a flat washer 15 are also provided at the top of the guide post 6 to abut against the guide sleeve 13. With the above design, different numbers of limiting posts 12 can be selected according to actual needs. When the snap ring 3 is assembled onto the component assembly, the limiting post 12 abuts against the movable plate, which can prevent the movable plate 1 from being excessively pressed down and affecting the assembly accuracy of the snap ring 3. The limiting post 12 can be flexibly replaced according to specific assembly requirements. The guide sleeve 13 can improve the smoothness and stability of the movable plate 1 moving along the guide post 6. The screw 14 and the flat washer 15 can abut against the guide sleeve 13 to prevent excessive rebound and safety issues such as the movable plate 1 falling off.
[0021] In use, a tooling frame is composed of a base 5, guide post 6, limit post 12, guide sleeve 13, movable plate 1, first elastic element 7, screw 14, and flat washer 15. A positioning seat 8 is installed on the base 5 of the frame, and a pressure head assembly consisting of an outer pressure head 9, a second elastic element 10, a snap ring pressure head 2, and a positioning pin 11 is installed on the movable plate 1 of the frame. Then, a set of four parts is placed on the positioning seat 8, and the snap ring 3 is installed on the snap ring pressure head 2, as shown below. Figure 2 As shown; the movable plate 1 is connected to an external pressure device, such as a press. When the press is started, the movable plate 1 moves downwards, causing the external pressure head 9 and the retaining ring pressure head 2 to move downwards synchronously, connecting the retaining ring pressure head 2 to the component assembly 4. At this time, the retaining ring pressure head 2 is fixed in place, and the external pressure head 9 abuts against the retaining ring 3, as shown. Figure 3 As shown; continue pressing down on the movable plate 1, causing it to compress the second elastic 10 and continue moving downwards. The outer pressure head 9 moves downwards along the retaining spring pressure head 2 via the slide 901, pressing the retaining spring 3 into the component assembly 4, until the positioning pin 11 is placed in the positioning groove at the upper end of the limiting slide 901, and the limiting post 12 abuts against the movable plate 1, as shown. Figure 4 As shown, the assembly of snap ring 3 is complete. The press is then turned off, and the movable plate returns to its original position. Figure 2 In this state, a round of pressing is completed. The operation is simple, the assembly consistency is good, and the efficiency is high.
[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
