Description

Technical Field

[0001] This invention belongs to the field of auxiliary tooling technology, specifically relating to a snap ring auxiliary installation device and its working method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In the field of mechanical assembly, snap rings, as a common fastening element, are widely used in shaft or hole structures to limit the axial displacement of components. Traditional snap ring installation methods typically rely on manual tools such as snap ring pliers. Operators must first insert the jaws of the pliers into the snap ring's opening, then manually expand it to deform it before inserting it into the predetermined position. However, due to the snap ring's high elasticity and small size, the expansion process of the snap ring's opening is difficult to control precisely when using snap ring pliers manually. Uneven force can easily cause the snap ring to suddenly pop out or undergo plastic deformation, affecting assembly quality and creating safety hazards. The degree of expansion of the snap ring each time depends on the operator's skill level and experience, exhibiting significant randomness and making it difficult to guarantee assembly consistency and reliability. Frequent use of snap ring pliers can easily cause operator fatigue, affecting assembly efficiency and further exacerbating uncertainties in the operation process. Alternatively, there are simple tools such as screwdrivers to pry open the snap ring, but this carries a higher risk of damage and also makes it impossible to control the expansion range, easily causing permanent deformation or damage to the snap ring, affecting its locking function. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a snap ring auxiliary installation device and working method, which solves the problems of inaccurate control of snap ring expansion process, easy snap ring ejection or deformation, and high fatigue strength in the prior art.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a snap ring auxiliary installation device, comprising: a worktable, a snap ring placement platform disposed on the worktable, the snap ring placement platform being mounted on a support platform via a sliding sleeve, a circular snap ring groove being horizontally disposed on the upper surface of the end of the snap ring placement platform, a workpiece hole being disposed at the bottom of the snap ring groove, the support platform also being disposed with a through hole, and a vertical groove being disposed at the end of the snap ring placement platform, the vertical groove communicating with the snap ring groove; a drive assembly is also disposed on the worktable, an inner support assembly is disposed on the drive assembly, the inner support assembly is disposed at the end of the snap ring placement platform near the snap ring groove, the inner support assembly includes a vertically arranged drive plate, an elliptical cylinder is disposed at the end of the drive plate near the vertical groove, the axis of the elliptical cylinder is parallel to the plane of the drive plate, and a limiting plate is disposed at the top of the elliptical cylinder, when the drive plate pushes the elliptical cylinder through the vertical groove and inserts it into the snap ring opening, the limiting plate is located on the upper surface of the snap ring placement platform, thereby limiting the snap ring in the vertical direction.

[0006] As a further implementation, a first cylinder is provided at the other end of the snap ring placement platform. The first cylinder is fixedly mounted on the support platform, and the telescopic rod of the first cylinder is fixedly connected to the snap ring placement platform.

[0007] As a further implementation, the legs of the support platform are provided with a contouring fixture, and a first detection component is provided below the support platform, with the first detection component arranged opposite to the contouring fixture.

[0008] As a further implementation, the drive component includes a movable slide rail disposed on the worktable, and a push cylinder is disposed in the movable slide rail.

[0009] As a further implementation, a second cylinder is provided on the movable slide rail via a support seat. The end of the second cylinder is provided with a mounting seat for mounting the inner support assembly. The end of the mounting seat is provided with a mounting groove. The drive plate of the inner support assembly is installed in the mounting groove and is fixedly clamped by fasteners.

[0010] As a further implementation, a protective shell is also provided on the workbench, and an operation window is opened in the middle of the protective shell. The operation window corresponds to the position of the snap ring groove and is used to place the snap ring and the workpiece.

[0011] As a further implementation, a second detection component, which is an infrared sensor, is provided on the protective shell on one side of the operation window.

[0012] As a further implementation, the workbench is fixedly mounted on the machine base, which is equipped with a main switch, a start button, and a material box.

[0013] As a further implementation, a control device is also included, which is connected to the first cylinder, the second cylinder, the drive cylinder, the first detection component, the second detection component, and the start button.

[0014] Secondly, the present invention also provides a method for operating the snap ring auxiliary installation device, comprising the following steps: Step 1: Power on the device via the main switch, place the snap ring on the snap ring placement platform, and press the start button; Step 2: The first cylinder starts and moves the snap ring placement platform until the workpiece hole coincides with the through hole on the support platform, then stops. At the same time, the drive cylinder and the second cylinder start, and the internal support assembly moves to the left through the vertical groove to open the snap ring. Step 3: Manually insert the workpiece shaft into the workpiece hole. The first detection component uses infrared detection to check whether the groove on the workpiece coincides with the infrared light. If they coincide, the second detection component checks whether the angle of the workpiece shaft is in place. Step 4: The second cylinder continues to drive the inner support assembly to move towards the side closest to the second cylinder until the retaining spring is fully engaged in the workpiece's slot. Step 5: Reset the drive cylinder, the first cylinder, and the second cylinder, and wait for the next operation.

[0015] Compared with the prior art, the advantages and positive effects of this invention are: The circular circlip groove on the circlip placement platform of this invention provides a fixed and standard placement position for the circlips, ensuring that each circlip is in the exact same position before installation, eliminating random errors caused by human placement. When the elliptical cylinder is inserted into the opening of the circlip through the vertical slot, its special cross-sectional shape allows the opening to be opened smoothly and controllably. Compared to prying it open directly with tools such as screwdrivers, this avoids the circlip popping out or deforming due to uneven force. The minor axis radius of the elliptical cylinder determines the maximum extent to which the circlip is opened, ensuring that the expansion amount of the circlip is consistent each time it is installed. This ensures smooth installation of the workpiece while avoiding permanent deformation or damage to the circlip due to over-expansion. When the elliptical cylinder is inserted, the limiting plate covers the upper surface of the circlip placement platform, pressing down on the circlip and preventing it from popping out of the circlip groove during expansion, improving operational safety and preventing part loss. At the same time, it reduces labor intensity and fatigue, avoiding fatigue caused by frequent use of circlip pliers and the safety hazard of popping out, while also improving the installation efficiency of the circlip.

[0016] The support platform of the present invention is provided with a contouring fixture on its legs. The first detection component is arranged opposite to the contouring fixture. The contouring fixture is similar in shape to the bottom end of the workpiece shaft. Since there are two planes symmetrically arranged on the bottom side of the workpiece shaft, the distance between the workpiece shaft and the first detection component is detected. Since the placement angle of the workpiece shaft is different, the distance between the first detection component and the workpiece shaft can be identified. The distance determines whether the workpiece shaft is placed in place. After it is placed in place, the contouring fixture is used to limit the movement to ensure the stability of the snap ring installation process.

[0017] The movable slide rail of the present invention is provided with a second cylinder via a support seat. The end of the second cylinder is provided with a mounting seat for mounting an inner support assembly. The end of the mounting seat is provided with a mounting groove. The drive plate of the inner support assembly is installed in the mounting groove and is fixedly clamped by fasteners. When the inner support assembly is worn or damaged, the inner support assembly can be loosened directly by fasteners to replace the inner support assembly. Attached Figure Description

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Example 1 This embodiment discloses a snap ring auxiliary installation device, such as Figures 1-3 As shown, the system includes: a worktable 1, on which a snap ring holder 3 is mounted, which is installed on a support platform 2 via a sliding sleeve 4; a circular snap ring groove 15 is horizontally provided on the upper surface of the end of the snap ring holder 3, and a workpiece hole is provided at the bottom of the snap ring groove 15; the support platform 2 also has a through hole for mounting a workpiece shaft 9 to the workpiece hole; a vertical groove is provided at the end of the snap ring holder 3, which communicates with the snap ring groove 15 for the passage of an inner support assembly 6; a drive assembly is also provided on the worktable 1, and the inner support assembly 6 is mounted on the drive assembly. The inner support assembly 6 is used to open the retaining ring 16. It is arranged at the end near the retaining ring placement platform 3 where the retaining ring groove 15 is provided. The inner support assembly 6 includes a vertically arranged drive plate 14. An elliptical cylinder 17 is provided at the end of the drive plate 14 near the vertical groove. The axis of the elliptical cylinder 17 is parallel to the plane of the drive plate 14. A limiting plate 18 is provided at the top of the elliptical cylinder 17. When the drive plate 14 pushes the elliptical cylinder 17 through the vertical groove and inserts it into the opening of the retaining ring 16, the limiting plate 18 is located on the upper surface of the retaining ring placement platform 3, thereby limiting the retaining ring 16 in the vertical direction. It can be understood that the circular retaining ring groove 15 on the retaining ring placement platform 3 provides a fixed and standard placement position for the retaining ring 16, ensuring that each retaining ring 16 is in the exact same position before installation, eliminating random errors caused by human placement. When the elliptical cylinder 17 is inserted into the opening of the retaining ring 16 through the vertical groove, its special cross-sectional shape allows the opening of the retaining ring 16 to be opened smoothly and controllably. Compared to prying it open directly with a screwdriver or other tools, this method avoids the possibility of the retaining ring 16 popping out or deforming due to uneven force. The minor axis radius of the elliptical cylinder 17 determines the maximum extent to which the retaining ring 16 can be stretched, and ensures that the expansion amount of the retaining ring 16 is consistent each time it is installed. This ensures that the workpiece can be smoothly installed, while avoiding permanent deformation or damage to the retaining ring 16 due to over-expansion. When the elliptical cylinder 17 is inserted, the limiting plate 18 covers the upper surface of the retaining ring placement platform 3 and presses down on the retaining ring 16, preventing the retaining ring 16 from popping upward from the retaining ring groove 15 during expansion. This improves operational safety and avoids the loss of parts. At the same time, it reduces labor intensity and fatigue, avoids fatigue caused by frequent use of retaining ring pliers, and avoids the safety hazard of popping out. It also improves the installation efficiency of the retaining ring 16.

[0023] As a further implementation, a first cylinder 5 is provided at the other end of the snap ring placement platform 3. The first cylinder 5 is fixedly mounted on the support platform 2, and the telescopic rod of the first cylinder 5 is fixedly connected to the snap ring placement platform 3 for driving the snap ring placement platform 3 to move, so as to facilitate the placement of the workpiece shaft 9 into the workpiece hole and the through hole.

[0024] As a further implementation, a contouring fixture 8 is provided on the legs of the support platform 2, and a first detection component 7 is provided below the support platform 2. The first detection component 7 is arranged opposite to the contouring fixture 8. The contouring fixture 8 is similar in shape to the bottom end of the workpiece shaft 9. Since there are two symmetrical planes on the bottom side of the workpiece shaft 9, the distance between the first detection component 7 and the workpiece shaft 9 is detected. Since the placement angle of the workpiece shaft 9 is different, the distance between the first detection component 7 and the workpiece shaft 9 can be identified. The distance determines whether the workpiece shaft 9 is placed in place. After it is placed in place, the contouring fixture 8 is used to limit the position to ensure the stability of the snap ring 16 during installation.

[0025] As a further implementation, the drive assembly includes a movable slide rail 11, which is disposed on the worktable 1. A push cylinder is disposed in the movable slide rail 11 to drive the second cylinder 12 to move in position and to provide stable support for the second cylinder 12.

[0026] As a further implementation, a second cylinder 12 is provided on the movable slide rail 11 via a support base 13. The end of the second cylinder 12 is provided with a mounting base 10 for mounting the inner support assembly 6. The end of the mounting base 10 is provided with a mounting groove. The drive plate 14 of the inner support assembly 6 is installed in the mounting groove and is fixedly clamped by fasteners. When the inner support assembly 6 is worn or damaged, it can be directly loosened by fasteners to replace the inner support assembly 6.

[0027] As a further implementation, the workbench 1 is also provided with a protective shell 23, and an operation window is provided in the middle of the protective shell 23. The operation window corresponds to the position of the snap ring groove 15 and is used to place the snap ring 16 and the workpiece.

[0028] As a further implementation, a second detection component 24 is provided on the protective shell 23 on one side of the operation window. The second detection component 24 is an infrared sensor. The infrared sensor checks whether the groove on the infrared detection workpiece coincides with the infrared light. If it coincides, the second detection component 24 detects whether the angle of the workpiece axis 9 is in place.

[0029] As a further implementation, the workbench 1 is fixedly mounted on the machine base 19, and the machine base 19 is equipped with a main switch 20, a start button 21, and a material box 22.

[0030] As a further implementation, a control device is also included, which is connected to the first cylinder 5, the second cylinder 12, the drive cylinder, the first detection component 7, the second detection component 24, and the start button 21.

[0031] Example 2 This embodiment discloses a method for operating a snap ring auxiliary installation device, including the following steps: Step 1: Power on the main switch 20, place the snap ring 16 on the snap ring placement platform 3, and press the start button 21; Step 2: The first cylinder 5 starts and drives the snap ring placement platform 3 to move until the workpiece hole coincides with the through hole on the support platform 2 and stops. At the same time, the drive cylinder and the second cylinder 12 start and drive the inner support assembly 6 to move to the left through the vertical groove to open the snap ring 16. Step 3: Manually insert the workpiece shaft 9 into the workpiece hole. The first detection component 7 uses infrared detection to check whether the groove on the workpiece coincides with the infrared light. If it does, the second detection component 24 checks whether the angle of the workpiece shaft 9 is in place. Step 4: The second cylinder 12 continues to drive the inner support assembly 6 to move towards the side closest to the second cylinder 12 until the snap ring 16 is fully engaged in the workpiece's slot. Step 5: Reset the drive cylinders, first cylinder 5 and second cylinder 12, and wait for the next operation.
