Description

Technical Field

[0001] The embodiments of this utility model belong to the field of snap ring opening technology, and more specifically, relate to a double-linkage pneumatic press for snap ring opening. Background Technology

[0002] Snap rings (also known as elastic retaining rings) are fastening elements commonly used in mechanical connections, widely applied to the axial fixation of components such as bearings, gears, and pulleys. Due to their advantages of simple structure, quick installation, and automatic positioning, they are widely used in industrial fields such as automobile manufacturing, machining, and home appliance assembly. However, in actual installation and disassembly processes, because of the high elasticity and small structural dimensions of snap rings, problems such as difficulty in opening, slippage, or damage to the workpiece often arise, especially in confined spaces or situations requiring high precision.

[0003] In existing technologies, retaining rings are typically made of elastic metal materials such as spring steel and stainless steel. Their openings are mostly radially shaped "C" notches (i.e., the opening plane is parallel to the retaining ring axis). The opening width is usually determined according to the nominal diameter of the retaining ring, generally 1 / 5 to 1 / 3 of the outer diameter of the retaining ring. Through this opening, the retaining ring can be opened or closed by external force (such as retaining ring clamps) to fit into mounting positions such as shaft grooves and hole grooves. After assembly, the opening naturally rebounds under the elastic action of the material, so that the inner ring (for shaft retaining rings) or the outer ring (for hole retaining rings) of the retaining ring fits tightly against the mounting surface, forming axial constraint. Summary of the Invention

[0004] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a double-linkage pneumatic press for opening retaining rings. Through the layered design of the mounting frame, a double-linkage mechanism between the pressing component and the worktable is achieved. A foot switch controls the pressing component to press downwards, fulfilling the requirement for opening the retaining ring. Another foot switch controls the fixed platform to push the worktable, precisely delivering the retaining ring to the designated installation position.

[0005] To achieve the above objectives, this utility model provides a double-linkage pneumatic press for opening retaining rings, comprising:

[0006] The mounting frame includes a base plate, a column with one end vertically mounted on the base plate, and a pressing mounting plate located at the other end of the column.

[0007] The pressing assembly located on the top of the mounting bracket includes a vertical pressing mechanism located on the pressing mounting plate, a pressing mounting block located on the top of the vertical pressing mechanism, and a pressing rod located in the mounting hole at the bottom of the pressing mounting block.

[0008] The fixed platform located at the bottom of the mounting frame includes a fixed platform mounting plate located at the top of the base plate, a push mounting plate located on one side of the top of the fixed platform mounting plate, a slide rail located in the middle of the fixed platform mounting plate, and a horizontal push mechanism located on the inner surface of the push mounting plate facing the slide rail.

[0009] The fixed platform includes a worktable located inside the slide rail and a screw mounting block located in the groove at the top of the worktable.

[0010] Furthermore, the fixed platform also includes a limiting plate disposed on the top of the fixed platform mounting plate.

[0011] Furthermore, the fixed platform also includes a limiting screw located in the mounting hole in the middle of the limiting plate.

[0012] Furthermore, the fixed platform also includes a starting rod disposed in the middle hole of the limiting plate.

[0013] Furthermore, the workbench also includes fixing screws located in mounting holes inside the screw mounting block.

[0014] Furthermore, a T-shaped groove extending from the top to the bottom is provided on one side of the working slider.

[0015] Furthermore, the worktable also includes a floating joint disposed in a T-slot on one side of the working slider.

[0016] Furthermore, the top of the base plate is provided with a T-shaped groove.

[0017] Furthermore, the vertical pressing mechanism is a linear motion structure.

[0018] Furthermore, the horizontal pushing mechanism is a linear motion structure.

[0019] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0020] 1. The press of this utility model achieves dual linkage between the pressing component and the worktable through the upper and lower layered design structure of the mounting frame.

[0038] This novel embodiment provides a double-linkage pneumatic press for opening a retaining ring 74. For example... Figure 1 As shown, the system includes a mounting frame 1, a foot switch 2, an air supply triplet 3, a solenoid reversing valve 4, a pressing assembly 5, a fixed platform 6, and a workbench 7. The mounting frame 1 serves as the mounting mechanism for the entire double-linkage pneumatic press. A foot switch 2 is mounted on the central connecting column 12 of the mounting frame 1. Another foot switch 2 is connected to a horizontal pushing mechanism 67 and positioned at a suitable location outside the double-linkage pneumatic press via a connecting cable. An air supply triplet 3 is mounted on the side of the pressing mounting plate 13 at the top of the mounting frame 1. The air supply triplet 3 includes a filter for purifying compressed air, a pressure reducing valve for stabilizing output pressure, and an oil mist lubricator for lubricating pneumatic components. A pressing assembly 5 is mounted on the outward-extending side of the pressing mounting plate 13 at the top of the mounting frame 1, and is controlled by the foot switch 2 mounted on the column 12. In the vertical linear motion, when the pressing component 5 moves downward, it presses down on the retaining ring 74 and completes the opening of the retaining ring 74; an adjustable fixed platform 6 is manually installed on the top of the base plate 11 at the bottom of the mounting frame 1. The worktable 7 installed on the fixed platform 6 is controlled by the foot switch 2 located at a suitable position outside the double linkage pneumatic press to move linearly in the horizontal direction. Through the horizontal movement of the horizontal pushing mechanism 67 inside the fixed platform 6, the retaining ring 74 is sent into the designated installation position; the worktable 7 is installed inside the slide rail 63 of the fixed platform 6. The worktable 7 can move linearly within the travel range of the slide rail 63. The retaining ring 74 is manually placed on the top surface of the screw mounting block 72 installed inside the worktable 7, with the middle ring of the retaining ring 74 placed on the protruding part outside the fixing screw 73. The worktable 7, through the fixing screw 73 that matches the shape of the retaining ring 74, ensures that the retaining ring 74 is placed without deviation, and achieves the accuracy and stability of the positioning of the retaining ring 74 through a simple structure. The press of this utility model achieves dual linkage between the pressing component and the worktable through the upper and lower layered design structure of the mounting frame. The pressing component is controlled by a foot switch to press down to complete the opening of the retaining ring. The fixed platform is controlled by a foot switch to push the worktable and accurately deliver the retaining ring to the designated installation position.

[0039] Specifically, such as Figure 1 As shown, the mounting frame 1 includes a base plate 11, a column 12, and a pressing mounting plate 13. One end of the column 12 is vertically inserted into a corresponding mounting hole in the base plate 11. A T-slot is formed at a suitable position on the top of the base plate 11, and multiple nuts are installed inside the T-slot. Corresponding holes are formed on the fixing platform mounting plate 61 of the fixing platform 6 for bolt connection with the nuts in the T-slot. Thus, the T-slot can adjust the actual installation position of the fixing platform 6 to a certain extent to achieve precise pushing of the retaining ring to the actual position. The other end of the column 12 is connected to the pressing mounting plate 13, which has mounting holes for an air source triplet 3, a solenoid reversing valve 4, and a pressing assembly 5. The press of this utility model, through the upper and lower layered design structure of the mounting frame, achieves dual linkage between the pressing assembly and the worktable. By forming a T-slot on the top of the pressing mounting plate, the fixing platform can be adjusted to a certain extent, ensuring the accuracy of the fixing platform in pushing the retaining ring to the designated position.

[0040] Specifically, such as Figure 1 , Figure 2 As shown, the pressing assembly 5 includes a pressing mounting block 51, a pressing rod 52, and a vertical pressing mechanism 53. The vertical pressing mechanism 53 is a linear motion structure, such as a standard cylinder with a square end cap. The vertical pressing mechanism 53 is mounted on the pressing mounting plate 13 of the mounting bracket 1 and is controlled by a foot switch 2 mounted on the column 12 to move linearly in the vertical direction. The top of the vertical pressing mechanism 53 is connected to the pressing mounting block 51. The side of the pressing mounting block 51 has multiple fastening screw holes (two in this embodiment), and the bottom of the pressing mounting block 51 has multiple mounting holes that match the pressing rod 52 (two in this embodiment). The pressing rod 52 is replaced according to the size of the retaining ring 74 and inserted into the mounting holes at the bottom of the pressing mounting block 51. The surface of the pressing rod 52 is pressed by the fastening screws on the side of the pressing mounting block 51 to prevent the pressing rod 52 from becoming loose. The press of this utility model controls the downward pressing component to press down through a foot switch to complete the opening of the retaining ring. The fastening screw holes on the side of the pressing mounting block prevent the pressing rod from loosening. The appropriate pressing rod can be replaced according to the actual size of the retaining ring being produced.

[0041] Specifically, such as Figure 3As shown, the fixed platform 6 includes a fixed platform mounting plate 61, a push mounting plate 62, a slide rail 63, a limit plate 64, a limit screw 65, a starting rod 66, and a horizontal pushing mechanism 67. The fixed platform mounting plate 61 is bolted to the T-slot of the lower pressure mounting plate 13 of the mounting bracket 1. The push mounting plate 62 is mounted at one end of the fixed platform mounting plate 61. The slide rail 63 is mounted in the middle of the fixed platform mounting plate 61, and a worktable 7 is mounted on the slide rail 63. The limit plate 64 is mounted at the other end of the fixed platform mounting plate 61. The limit plate 64 has mounting holes for the limit screw 65 and the starting rod 66. The limit screw 65 is used for... To ensure the snap ring 74 is accurately delivered to the designated position, the starting rod 66 has rubber blocks embedded at both ends to cushion collisions. Pushed by the worktable 7, the starting rod 66 touches the foot switch 2 mounted on the column 12, thus activating the pressing assembly 5 to push the snap ring 74 downwards. The horizontal pushing mechanism 67 is a linear motion structure, such as a compact cylinder. Mounted on the pushing mounting plate 62, it is controlled by the foot switch 2, located at a suitable position outside the double-linkage pneumatic press, to perform horizontal linear motion. The top of the horizontal pushing mechanism 67 is connected to the worktable 7. This press, controlled by a foot switch, pushes the fixed platform to the worktable, accurately delivering the snap ring to the designated installation position. A slide rail guides the linear motion of the worktable, and a limit screw controls the pushing distance, achieving precise control of the snap ring's position. When the worktable reaches the designated position, it pushes the starting rod to touch the foot switch, achieving double-linkage operation.

[0042] Specifically, such as Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the worktable 7 includes a working slider 71, a screw mounting block 72, a fixing screw 73, a retaining ring 74, and a floating joint 75. The working slider 71 is installed inside the slide rail 63 of the fixed platform 6. A screw hole is provided on the side of the working slider 71, and a groove is provided on the top of the working slider 71. The screw mounting block 72 is installed in the groove, and the screw mounting block 72 is fixed to the side with a screw. Two screw mounting holes are provided inside the screw mounting block 72. The fixing screw 73 is installed on the screw mounting block 72 from the inside out, and the fixing screw is then fixed to the screw. The bottom of the screw 73 protrudes from the top surface of the screw mounting block 72; the retaining ring 74 is manually placed on the top surface of the screw mounting block 72 installed inside the worktable 7, with the middle ring of the retaining ring 74 positioned outside the protruding part of the fixing screw 73; a T-slot penetrating the top and bottom is opened at one end of the working slide block 71, and a floating joint 75 is installed in the T-slot. The floating joint 75 is connected to the horizontal pushing mechanism 67 in the fixed platform 6 and is used to eliminate installation deviation and force misalignment between the horizontal pushing mechanism 67 and the worktable 7, protect the horizontal pushing mechanism 67, and improve transmission stability. The press of this utility model achieves the accuracy and stability of retaining ring positioning through the fixing screw that matches the shape of the retaining ring, and ensures the transmission stability of the worktable under the push of the horizontal pushing mechanism through the floating joint installed in the T-slot on the working slide block.

[0043] In another embodiment of this utility model, the working method of the double-linkage pneumatic press for opening the retaining ring is as follows:

[0044] Based on the actual size of the retaining ring 74, select the appropriate pressing rod 52 and fixing screw 73, and adjust the actual installation position of the fixing platform 6 on the mounting bracket 1 to ensure that the retaining ring 74 is accurately positioned and the press is highly synchronized.

[0045] The operator manually snaps the retaining ring 74 into the external protruding part of the fixing screw 73 in the workbench 7, with the bottom surface of the retaining ring 74 fitting against the top surface of the screw mounting block 72.

[0046] When the operator presses the foot switch 2 on the outside of the double-linkage pneumatic press, the retaining ring 74 is pushed to the designated position by the horizontal pushing mechanism 67.

[0047] Driven by the starter lever 66, the foot switch 2 located on the column 12 is activated, the pressing component 5 starts to work, and the pressing lever 52 presses downward under the action of the vertical pressing mechanism 53.

[0048] After the clasp 74 is opened once, the vertical pressing mechanism 53 and the horizontal pushing mechanism 67 return to their original positions. The operator then manually removes the clasp 74 that has been opened and inserts the next clasp 74.

[0049] Repeat the above process to sustainably complete the opening of the clasp 74.

[0050] In summary, this dual-linkage pneumatic press for opening retaining rings avoids multiple positioning and repetitive operations, and is easy to operate, has accurate positioning, and strong synchronization. It is particularly suitable for batch assembly lines of small and medium-sized parts or multi-station synchronous pressing processes.

[0051] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
