Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, and in particular to a quick positioning device for assembling retaining rings. Background Technology

[0002] A retaining circumference is a ring-shaped metal part that achieves fastening and positioning functions through elastic deformation. It prevents axial movement of parts on a shaft, acting as a limiter, and is widely used in machinery manufacturing, automotive, aerospace, and other fields. Assembly slot shafts with retaining circumferences can precisely fix various parts in designated positions on the shaft, ensuring stable operation of the mechanical system. Retaining circumference assembly and positioning devices mainly consist of a positioning base, a guide mechanism, and clamping components, used for fixing the workpiece, guiding the retaining circumference, and clamping and positioning, respectively.

[0003] When using this device, first place the shaft to be assembled on the positioning base, align the retaining ring with the installation position using the guide mechanism, then fix the shaft with the clamping assembly, and finally push the retaining ring into the assembly slot along the guide groove. The entire operation process is simple and efficient, improving the accuracy and speed of retaining ring assembly, reducing operational errors, and ensuring assembly quality.

[0004] In existing technologies, positioning seats are mostly fixed to the worktable with bolts. Each time they are replaced, tools are needed to loosen and tighten the bolts, which involves many steps, is time-consuming and labor-intensive, and makes it difficult to quickly adapt to different models of assembly slot shafts. This seriously restricts assembly efficiency. Furthermore, the bolt fixing method cannot guarantee the accurate installation of the positioning seat, has poor stability, and is prone to positioning deviations, which leads to a decrease in the assembly accuracy of the snap ring and affects the overall production efficiency and product quality. Therefore, a quick positioning device for snap ring assembly is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Reference Figures 1 to 3 The present invention provides an embodiment of a quick positioning device for assembling snap rings, comprising an assembly table 1, which is the basic support component of the entire device and provides a reliable reference for the installation of subsequent components. A quick-release positioning mechanism is fixedly connected to the top of the assembly table 1, and an mounting block 14 is fixedly connected to the top of the assembly table 1. The mounting block 14 is the mounting base component of the auxiliary fixing mechanism and provides a mounting base for fixing components such as cylinder 17. Through precise structural design, a stable clamping of the assembly groove shaft is achieved, improving the assembly positioning accuracy and stability. An auxiliary fixing mechanism is slidably connected to the inner side of the mounting block 14.

[0034] The quick-release positioning mechanism includes a fixing slot 5, which is a key component of the quick-release positioning mechanism. It provides installation and sliding space for the guide mounting assembly, unlocking lever 7, etc., enabling quick installation and replacement of the positioning seat 12, precise positioning, and reliable locking and unlocking. It is compatible with different models of positioning seats 12. The bottom of the fixing slot 5 is fixedly connected to the top of the assembly table 1. The guide mounting assembly is slidably connected to the outer side of the fixing slot 5, and the unlocking lever 7 is slidably connected to the inner side of the fixing slot 5. The unlocking lever 7 overcomes the spring of the locking spring 9 under external force. The force moves the locking cone 8 outward, controlling the locking lever 10 to move inward, thus unlocking the positioning seat 12 for quick disassembly and replacement. A locking spring 9 is sleeved on the outer side of the unlocking lever 7. The locking spring 9 provides an inward pushing force to the unlocking lever 7 using its own elasticity, maintaining contact between the locking cone 8 and the locking lever 10, ensuring the locking state of the positioning seat 12. A locking cone 8 is fixedly connected to the outer side of the unlocking lever 7 away from the locking spring 9. The locking cone 8 is connected to the unlocking lever 7 and, through its own conical structure,... When the unlocking lever 7 is pulled by an external force, the locking lever 10 slides along its inclined surface and gradually retracts inward, thus unlocking. After the external force is removed, the locking lever 10 assists in resetting the locking positioning seat 12. The outer side of the locking cone 8 is slidably connected to the inner side of the fixing groove 5, and the inner side of the fixing groove 5 is slidably connected to the locking lever 10. In its natural state, the unlocking spring 11 pushes the locking lever 10 to move towards the positioning seat 12, so that its locking structure is embedded in the slot of the positioning seat 12, thereby locking the positioning seat 12. The outer side of the locking lever 10 is sleeved... An unlocking spring 11 is provided. When the device is working normally, the unlocking spring 11 is in a compressed state. When the locking cone 8 releases its support on the locking engagement rod 10, the unlocking spring 11 releases its elastic potential energy and stretches outward, causing the locking engagement rod 10 to retract inward and disengage from the engagement groove of the positioning seat 12, thereby unlocking. The positioning seat 12 is slidably connected to the outside of the fixing slot block 5. The positioning seat 12 is a key component for installing and positioning the retaining ring. Its top is provided with an installation slot adapted to place the assembly slot shaft, so as to achieve quick positioning when installing the retaining ring on the assembly slot shaft.

[0035] One end of the locking lever 10 is slidably connected to the inside of the positioning seat 12, and the other end of the locking lever 10 is in contact with the conical surface of the locking cone 8;

[0036] The guide mounting assembly includes a guide rib 13, which precisely matches the guide mounting groove 6 on the fixed slot block 5 to provide stable guidance for the installation and disassembly of the positioning seat 12, ensuring its accurate movement trajectory, improving positioning accuracy and assembly efficiency. The outer side of the guide rib 13 is fixedly connected to the inner side of the bottom of the positioning seat 12. Multiple guide mounting grooves 6 are opened on the outer side of the fixed slot block 5. The guide mounting grooves 6 are adapted to the guide rib 13 at the bottom of the positioning seat 12 to provide precise guidance for the installation and disassembly process of the positioning seat 12, ensuring its smooth sliding and ensuring the accuracy and stability of the installation position of the positioning seat 12. The outer side of the guide rib 13 is slidably connected to the inner side of the guide mounting groove 6.

[0037] One end of the locking spring 9 is fixedly connected to the outside of the unlocking lever 7, and the other end of the locking spring 9 is fixedly connected to the inside of the fixing slot 5. One end of the unlocking spring 11 is fixedly connected to the outside of the locking lever 10, and the other end of the unlocking spring 11 is fixedly connected to the inside of the fixing slot 5.

[0038] The top of the assembly table 1 is fixedly connected to a lower pressure arm 2. The lower pressure arm 2, in cooperation with the control lever 3, drives the assembly pressure ring 4 to slide up and down, thereby pressing down on the retaining ring for assembly. This provides a force structure for the retaining ring assembly, ensuring a stable and efficient assembly process. The inner side of the lower pressure arm 2 is rotatably connected to the control lever 3, which is rotatably connected to the lower pressure arm 2. By moving the control lever 3, the operator can drive the assembly pressure ring 4 to precisely press down or lift, achieving stable assembly and reset of the retaining ring. The bottom of the lower pressure arm 2 is slidably connected to the assembly pressure ring 4. Driven by the control lever 3, the assembly pressure ring 4 slides along the lower pressure arm 2, applying uniform pressure to the retaining ring through the flat surface at the bottom, precisely pressing the retaining ring into the shaft groove of the assembly slot, ensuring the accuracy and reliability of the retaining ring assembly.

[0039] Reference Figure 1 , Figure 3 and Figure 4The auxiliary fixing mechanism includes a fixing cylinder 17, which acts as a power source, outputting telescopic force. This force, via a transmission rod 18, drives the clamping slide rod 20, enabling the fixing jaws 16 to clamp and release the assembly groove shaft. This ensures the stable and reliable positioning of the snap ring assembly. The outer side of the fixing cylinder 17 is fixedly connected to the inner side of the mounting block 14. The drive end of the fixing cylinder 17 is rotatably connected to the transmission rod 18. The transmission rod 18 rotates around the rotating seat 19, converting the telescopic force of the fixing cylinder 17 into linear motion of the clamping slide rod 20, thus achieving the clamping and releasing of the snap ring. The outer side of the mounting block 14 is fixedly connected to a rotating... The rotating seat 19 provides a stable rotation fulcrum for the transmission rod 18, ensuring its smooth rotation when transmitting power to the fixed cylinder 17, ensuring the precise action of the clamping slide rod 20, and reliably fixing the retaining ring. The inner side of the middle section of the transmission rod 18 is rotatably connected to the outer side of the rotating seat 19. The end of the transmission rod 18 away from the fixed cylinder 17 is rotatably connected to the clamping slide rod 20. The clamping slide rod 20 slides within the mounting block 14 under the push of the transmission rod 18, causing the fixed clamping claw 16 to clamp or release the retaining ring. It is reset with the return spring 21 and guided by the guide slide rod 15 to achieve precise and stable auxiliary fixing of the retaining ring.

[0040] The outer side of the clamping slide rod 20 is slidably connected to the inner side of the mounting block 14. A return spring 21 is sleeved on the outer side of the clamping slide rod 20. The return spring 21 stores force when the fixed claw 16 clamps the retaining ring. When the external force is removed, it releases elastic potential energy, pushing the clamping slide rod 20 to drive the fixed claw 16 to return to its original position, ensuring that the auxiliary fixing mechanism works stably in a cycle. One end of the return spring 21 is fixedly connected to the inner side of the mounting block 14, and the other end of the mounting block 14 is fixedly connected to the outer side of the clamping slide rod 20. The end of the clamping slide rod 20 away from the transmission rotating rod 18 is fixedly connected to the fixed claw 16. The fixed claw 16 moves precisely under the assistance of the guide slide rod 15 driven by the clamping slide rod 20, contacts and clamps the retaining ring, provides stable positioning support for the retaining ring assembly, and ensures that the position of the assembly groove shaft is fixed and does not shift during the assembly process.

[0041] Two guide slide rods 15 are fixedly connected to the inner side of the mounting block 14. The guide slide rods 15 provide precise guidance for the movement of the fixed claw 16, ensuring that it runs smoothly during the clamping or loosening of the clasp, avoiding deviation, and improving the accuracy and reliability of the clasp auxiliary fixation. The inner side of the fixed claw 16 is slidably connected to the outer side of the guide slide rods 15.

[0042] Working principle: First, install the positioning seat 12. According to the assembly requirements, select the appropriate model of positioning seat 12 and align the guide rib 13 at the bottom of the positioning seat 12 precisely with the guide mounting groove 6 on the outside of the fixing block 5. Slide the positioning seat 12 smoothly along the guide mounting groove 6 until it is installed in place. At this time, the locking lever 10 is pushed by the unlocking spring 11, and its locking structure is embedded in the slot of the positioning seat 12 to lock the positioning seat 12 and ensure its stable installation.

[0043] When the positioning seat 12 needs to be replaced, pull the unlocking lever 7 to overcome the elastic force of the locking spring 9, causing the locking cone 8 to move outward. The locking engagement lever 10 slides along the inclined surface of the locking cone 8 and gradually retracts inward, disengaging from the engagement groove of the positioning seat 12 and unlocking. At this time, the positioning seat 12 can be smoothly pulled out along the guide mounting groove and replaced with a new positioning seat 12 that fits. Repeat the above installation steps to complete the installation of the new positioning seat 12.

[0044] After the positioning seat 12 is installed, the assembly slot shaft is placed in the installation slot opened on the top of the positioning seat 12. Then, the auxiliary fixing mechanism is activated, and the fixing cylinder 17 outputs telescopic power to drive the transmission rod 18 to rotate around the rotating seat 19. The transmission rod 18 pushes the clamping slide 20 to slide in the mounting block 14. The fixing claw 16 moves precisely with the assistance of the guide slide 15, contacts and clamps the assembly slot shaft, and prevents it from shifting during the snap ring assembly process, providing stable positioning support for snap ring assembly.

[0045] After the assembly groove shaft is fixed, the retaining ring is placed in the groove of the assembly groove shaft. The operator moves the control lever 3 to drive the assembly pressure ring 4 to slide down along the lower pressure arm 2. The flat surface at the bottom of the assembly pressure ring 4 applies uniform pressure to the retaining ring, accurately pressing the retaining ring into the groove of the assembly groove shaft. After the assembly is completed, the control lever 3 is moved in the opposite direction to drive the assembly pressure ring 4 to reset, releasing the pressure on the retaining ring and completing the pressing assembly of the retaining ring.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
