Description

Technical Field

[0001] This application relates to the field of mechanical seal manufacturing and processing technology, and in particular to a press-fitting device for mechanical seal manufacturing and processing. Background Technology

[0002] A mechanical seal is a device that prevents fluid leakage. It consists of at least one pair of end faces perpendicular to the axis of rotation, which are kept in contact and slide relative to each other under the action of fluid pressure, the elastic force (or magnetic force) of the compensation mechanism, and the cooperation of auxiliary seals. It is one of the basic mechanical components with precision and relatively complex structure, and is a key component of various pumps, reaction synthesis vessels, turbine compressors, and other equipment. A mechanical seal consists of a main seal (dynamic ring, stationary ring), an auxiliary seal (sealing ring), a clamping component (horizontal spring, push ring), and a transmission component (horizontal spring seat and key or fixing screw). The assembly of the main seal and the auxiliary seal often requires the use of press-fitting equipment. This equipment uses a cylinder to push a pressure plate to move, so that the auxiliary seal and the main seal are pressed together to prevent the connection from loosening.

[0003] However, existing press-fitting equipment still has some defects in use: if the main seal and the auxiliary seal are tilted to each other during the press-fitting process, they cannot be fully connected, resulting in poor sealing effect. In actual press-fitting, it takes a long time for workers to fix and accurately align the main seal and the auxiliary seal, which affects processing efficiency. Summary of the Invention

[0004] This application proposes a press-fitting device for the production and processing of mechanical seals, which has the advantages of effectively adjusting the position of the sealing ring and sealing ring in a simple way, enhancing the alignment between the two, improving processing efficiency, and ensuring the quality of finished products, thereby solving the problem of time-consuming and inefficient alignment operations of the sealing ring and sealing ring.

[0005] To achieve the above objectives, this application adopts the following technical solution: a press-fitting device for the production and processing of mechanical seals, comprising: A left limiting mechanism is movably disposed on the top left side of the worktable. The left limiting mechanism includes a limiting frame, a limiting component, a limiting ring, a limiting membrane, a movable component, and a main adjustment component. A right limiting mechanism is movably disposed on the top right side of the worktable. The right limiting mechanism includes a limiting frame, a limiting component, a limiting ring, a limiting membrane, a movable component, and a fine-tuning component. The middle part of the limiting frame is fixedly sleeved to the top of the limiting member, and a limiting hole is opened inside the top of the limiting member. A limiting ring is provided above the limiting member, and a limiting membrane is provided between the limiting member and the limiting ring. A sealing ring can be placed in the limiting hole of the left limiting mechanism. An installation groove is provided on the outer wall of the top of the sealing ring, and the height of the installation groove of the sealing ring is higher than the height of the top of the limiting ring during the pressing stage. Movable components are provided on the left and right sides of the limiting frame, and the movable components are connected to the limiting ring. A main adjustment component is provided inside the limiting member on the left limiting mechanism, and there are six main adjustment components. The lifting and lowering of the movable components can control the six main adjustment components to apply the same thrust to the sealing ring at the same time, so that the sealing ring can be adjusted in a simple way to align the center of the sealing ring with the center of the limiting hole.

[0006] Furthermore, a sealing ring can be placed in the limiting hole of the right limiting mechanism. A fine-tuning component is provided inside the limiting member on the right limiting mechanism, and there are several fine-tuning components. By raising and lowering the movable component, several fine-tuning components can be controlled to reciprocate and apply the same thrust to the sealing ring, so that the sealing ring can be adjusted in a simple way to achieve alignment between the center of the sealing ring and the center of the limiting hole.

[0007] Furthermore, the worktable is vertically provided with a working circular groove, and the bottom end of the limiting frame is movably engaged in the working circular groove; the worktable is vertically provided with a working circular hole, and the limiting component is movably sleeved in the working circular hole. The limiting hole has a T-shaped cross-section. For the right limiting mechanism, the upper half diameter of the limiting hole is larger than the outer diameter of the sealing ring, and the lower half diameter is adapted to the inner diameter of the sealing ring. For the left limiting mechanism, the upper half diameter of the limiting hole is larger than the outer diameter of the sealing ring, and the lower half diameter is adapted to the inner diameter of the sealing ring. The inner diameter of the limiting ring is equal to the upper half diameter of the limiting hole; The limiting membrane, the limiting component, and the limiting ring form a sealed space, which is called the limiting cavity.

[0008] Furthermore, the active component includes: Movable cylinders are fixedly engaged on both the left and right sides of the limiting frame; The movable component is L-shaped, with one end movably connected to the movable cylinder and the other end fixedly connected to the side wall of the limiting ring.

[0009] Furthermore, several fine-tuning components are evenly arranged around the limiting member, and the fine-tuning components include: A fixing tube, which is L-shaped and is fixedly sleeved inside a limiting member, with one end of the fixing tube fixedly connected to the limiting cavity and the other end of the fixing tube fixedly connected to the upper half of the limiting hole. The fixing bladder is fixedly connected to the upper half of the wall of the limiting hole corresponding to the position of the fixing tube, and the fixing bladder and the limiting member are connected by a horizontal spring.

[0010] Furthermore, the top end of the limiting ring is fixedly connected to three sets of buffer rings, and the center of the three sets of buffer rings is concentric with the center of the limiting ring. Each set of buffer rings consists of two rubber rings with different cross-sectional shapes. One rubber ring has a right-angled triangle cross-section, and the other rubber ring has a right-angled trapezoid shape. A gap hole is provided between the two rubber rings.

[0011] Furthermore, the six main tuning components are evenly arranged around the limiting member, and the main tuning component includes: The push tube is T-shaped with a 90-degree rotation, and the lower half of the push tube has an inverted L-shaped push cavity. A push rod, one end of which is fixedly connected to the bottom end of a limiting ring, and the other end of which passes through the upper half of a push tube and is movably sleeved with the vertical inner wall of the push cavity; A pusher is movably sleeved with the transverse inner wall of the push cavity, and the push cavity area located between the bottom end of the push rod and the tail of the pusher is filled with a solution; A steel rope is used to connect the bottom end of the push rod to the tail end of the push member. A fixed sleeve is fixedly connected to the transverse inner wall of the push cavity near the vertical inner wall, and the steel rope passes through the fixed sleeve. A push bladder is fixedly connected between the bottom end of the push rod and the inner bottom end of the push tube, and the push bladder is filled with a solution. The guide tube has its lower half fixedly sleeved with the push rod and its upper half fixedly sleeved with the limiting ring. One end of the guide tube is connected to the inside of the push bladder, and the other end of the guide tube is located below the buffer ring. A vertical rod is movably sleeved at the guide tube port located below the buffer ring, and the vertical rod is connected to the inner wall of the guide tube through a vertical spring. The vertical rod is located below the gap hole between the two rubber rings.

[0012] By setting a main adjustment component inside the limiting member of the left limiting mechanism and setting movable components on both sides of the limiting ring of the left limiting mechanism, the movable components control the movement of the limiting ring, which synchronously drives the push rod to move. Under the action of the solution in the pushing cavity area, the push member and the steel rope are moved. When the limiting ring moves to the highest point, the head of the push member moves out of the lateral interior of the pushing cavity and can move into the limiting hole of the limiting member, realizing the action of the main adjustment component on the sealing ring, so as to adjust the position of the sealing ring placed in the limiting hole, thereby improving work efficiency. When the limiting ring moves to the lowest point, the head of the push member can move into the lateral interior of the pushing cavity, realizing the release of the sealing ring by the main adjustment component, so as to pick up the pressed finished product, further improving work efficiency. Compared with the traditional positioning claw, there is no need to position and remove the sealing ring one by one, making the operation simple and convenient.

[0013] By setting a push bladder below the push rod and a guide tube inside the push rod, when the push rod moves downward synchronously under the drive of the limit ring, it effectively squeezes the solution in the push bladder, causing the solution to move back and forth into the guide tube and push the vertical rod to move in the spacer hole. This helps to fully push the buffer ring vertically, allowing the buffer ring to adjust its shape in a timely and sufficient manner, shortening the recovery time of the buffer ring, and ensuring the normal use of the buffer ring during the pressing stage.

[0014] Furthermore, it also includes a moving mechanism and a pressing mechanism. The moving mechanism is fixedly installed on the rear side of the top of the worktable, and the pressing mechanism is movably installed on the front side of the moving mechanism.

[0015] Furthermore, the moving mechanism includes: A movable frame is fixedly installed on the rear side of the top of the workbench, and a movable slot is provided on the movable frame; A movable shaft is movably disposed within the movable slot of the movable frame, and a motor is movably connected to one end of the movable shaft that passes through the movable frame.

[0016] Furthermore, the pressing mechanism includes: A fixed frame, the rear side of which is movably engaged with the movable slot of the movable frame, and the rear side of the fixed frame is threadedly engaged with the movable shaft. A fixed cylinder is fixedly sleeved on the front middle part of the fixed frame; The fixed column is fixedly sleeved at one end of the fixed cylinder. The fixed column is composed of a large cylinder, a large frustum, a small cylinder, and a small frustum, and the dimensions of the fixed column gradually decrease from top to bottom. The diameter of the large cylinder is adapted to the inner diameter of the sealing ring, and the diameter of the small cylinder is adapted to the inner diameter of the sealing ring. A lifting cylinder assembly is fixedly sleeved in a fixed frame located in front of and behind the fixed column; The bottom end of the lifting cylinder assembly is fixedly connected to the top end of the pressure plate. A circular hole is provided in the middle of the pressure plate, and the fixing column can pass through the circular hole. The pressure plate has an outer positioning ring and an inner positioning ring. The bottom end of the pressure plate is movably engaged with the outer positioning ring and the inner positioning ring, which are concentrically arranged. The inner positioning ring is located inside the outer positioning ring, and the gap between the outer positioning ring and the inner positioning ring corresponds to the position of the innermost buffer ring. When the inner positioning ring is not squeezed or pushed, the inner positioning ring does not fit with the sealing ring. The outer positioning ring and the inner positioning ring are made of rubber.

[0017] By setting three sets of buffer rings at the top of the limiting ring of the left limiting mechanism, and setting an outer positioning ring and an inner positioning ring at the bottom of the pressure plate, when the pressure plate is pressed down above the limiting ring, the buffer ring, the outer positioning ring, and the inner positioning ring have a buffering effect, thereby improving the protection of the pressing mechanism and the left limiting mechanism. In addition, when the outer positioning ring and the inner positioning ring contact the buffer ring, the inner positioning ring will change direction under the limitation of the buffer ring, thereby effectively applying a thrust towards the sealing ring, further ensuring that the sealing ring is completely pressed into the mounting groove of the sealing ring.

[0018] The beneficial effects of this invention are as follows: This application provides a press-fitting device for the production and processing of mechanical seals. By setting a left limiting mechanism on the worktable, the left limiting mechanism includes a limiting element, a limiting ring, a buffer ring, a movable component, and a main adjusting component. When the sealing ring is inserted into the limiting hole of the limiting element, and the press-fitting mechanism operates above the right limiting mechanism, the movable component drives the limiting ring to move up and down, causing the height of the space within the limiting cavity to continuously change. This effectively controls the six main adjusting components to simultaneously apply the same thrust to the sealing ring. The position of the sealing ring within the limiting hole can be adjusted with a simple lifting and lowering operation, aligning the center of the sealing ring with the center of the limiting hole. This ensures accurate alignment of the sealing ring and the sealing ring during the press-fitting stage. In summary, the left limiting mechanism effectively simplifies the steps for adjusting the position of the sealing ring within the limiting hole, reduces wasted time, improves processing efficiency, and guarantees the quality of the finished product.

[0019] By setting a right limiting mechanism on the worktable, which includes a limiting component, a limiting ring, a movable component, and a fine-tuning component, when the sealing ring is inserted into the limiting hole of the limiting component and the pressing mechanism is working above the left limiting mechanism, the movable component drives the limiting ring to move up and down, causing the height of the limiting cavity to change continuously. This effectively controls multiple fine-tuning components to synchronously and reciprocally apply the same thrust to the sealing ring. The position of the sealing ring in the limiting hole can be adjusted with a simple lifting operation, aligning the center of the sealing ring with the center of the limiting hole. This facilitates the pressing mechanism's feeding operation of the sealing ring. In summary, the setting of the right limiting mechanism effectively simplifies the steps of adjusting the position of the sealing ring in the limiting hole, reduces time waste, improves processing efficiency, and ensures the quality of the finished product.

[0020] In summary, by using the right and left limit mechanisms in combination, and alternately activating the moving components on the right and left limit mechanisms, the sealing ring and sealing ring can be positioned and adjusted at reasonable times. This effectively enhances the alignment accuracy of the sealing ring and sealing ring, further reduces time waste, improves processing efficiency, and ensures the quality of the finished product.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: A press-fitting device for the production and processing of mechanical seals, including a worktable 1, such as... Figures 1-2 A right limiting mechanism 4a is movably installed on the right side of the top of the worktable 1, and a left limiting mechanism 4b is movably installed on the left side of the top of the worktable 1. The right limiting mechanism 4a includes a limiting frame 41, a limiting element 42, a limiting ring 43, a limiting membrane 44, a movable component 6, and a fine-tuning component 7, which provides space for the placement of the sealing ring 11. The left limiting mechanism 4b includes a limiting frame 41, a limiting element 42, a limiting ring 43, a limiting membrane 44, a movable component 6, and a main adjustment component 8, which provides space for the placement of the sealing ring 12. Specifically: like Figures 4-5 The middle part of the limiting frame 41 is fixedly sleeved to the top of the limiting member 42, and a limiting hole is opened inside the top of the limiting member 42. A sealing ring 11 can be placed in the limiting hole of the right limiting mechanism 4a, and a sealing ring 12 can be placed in the limiting hole of the left limiting mechanism 4b. The cross-sectional shape of the limiting hole is T-shaped. Figures 9-10 For the right limiting mechanism 4a, the upper half of the limiting hole has a larger diameter than the outer diameter of the sealing ring 11, while the lower half of the limiting hole is adapted to the inner diameter of the sealing ring 11. This facilitates the downward movement of the fixing post 33 into the limiting hole, thereby allowing the sealing ring 11 to be removed and improving the convenience of the loading operation. Figures 13-14 , Figure 17 For the left limiting mechanism 4b, the upper half diameter of the limiting hole is larger than the outer diameter of the sealing ring 12, and the lower half diameter of the limiting hole is adapted to the inner diameter of the sealing ring 12. This helps the fixing post 33 to move down into the limiting hole, thereby aligning the sealing ring 11 and the sealing ring 12 with each other, effectively pushing the sealing ring 11 and the sealing ring 12 to press accurately together, and improving the convenience of the pressing operation.

[0025] like Figures 1-2 , Figures 6-7 The worktable 1 has a vertically opening working circular groove, and the bottom end of the limiting frame 41 is movably engaged in the working circular groove. The worktable 1 has a vertically opening working circular hole, and the limiting member 42 is movably sleeved in the working circular hole. The setting of the limiting frame 41 and the limiting member 42 on the worktable 1 helps to improve the stability of the right limiting mechanism 4a and the left limiting mechanism 4b on the worktable 1.

[0026] like Figure 9 , Figure 13 A limiting ring 43 is provided above the limiting member 42. The inner diameter of the limiting ring 43 is equal to the upper half diameter of the limiting hole. For the right limiting mechanism 4a, it helps the fixing post 33 pass through the limiting ring 43 to take the sealing ring 11. For the left limiting mechanism 4b, it helps the fixing post 33 carry the sealing ring 11 through the limiting ring 43 to press it into the sealing ring 12. It should be noted that the top outer wall of the sealing ring 12 is provided with an installation groove, and during the pressing stage, the height of the installation groove of the sealing ring 12 is higher than the top height of the limiting ring 43, so that the pressing mechanism 3 can press the sealing ring 11 into the installation groove of the sealing ring 12.

[0027] like Figures 10-11 , Figures 14-15A limiting membrane 44 is provided between the limiting member 42 and the limiting ring 43, and the limiting membrane 44, the limiting member 42, and the limiting ring 43 form a sealed space, which is called the limiting cavity. For the right limiting mechanism 4a, the change in the height of the limiting cavity can provide power for the operation of multiple fine-tuning components 7 at the same time. For the left limiting mechanism 4b, the change in the height of the limiting cavity can provide power for the operation of multiple main adjustment components 8 at the same time.

[0028] Based on the configuration of the right limiting mechanism 4a and the left limiting mechanism 4b, it can be seen that the limiting frame 41, limiting member 42, limiting ring 43, and limiting membrane 44 of the right limiting mechanism 4a have the same structure as the limiting frame 41, limiting member 42, limiting ring 43, and limiting membrane 44 of the left limiting mechanism 4b, but their dimensions are different. The dimensions of the right limiting mechanism 4a meet the placement requirements of the sealing ring 11, and the dimensions of the left limiting mechanism 4b meet the placement requirements of the sealing ring 12.

[0029] like Figures 4-5 Movable components 6 are provided on the left and right sides of the limiting frame 41, and the movable components 6 are connected to the limiting ring 43. The movable components 6 include a movable cylinder 61 and a movable part 62. Movable cylinders 61 are fixedly engaged on the left and right sides of the limiting frame 41. The movable part 62 is L-shaped, and one end of the movable part 62 is movably connected to the movable cylinder 61. The other end of the movable part 62 is fixedly connected to the side wall of the limiting ring 43. When the movable cylinder 61 is activated, the movable cylinder 61 can drive the movable part 62 to move up and down, thereby driving the limiting ring 43 to move up and down, thus providing power for adjusting the sealing ring 11 and the sealing ring 12. It should be noted that when the right limiting mechanism 4a and the left limiting mechanism 4b adjust the position of the sealing ring 11 and the sealing ring 12, the movable part 62 can be raised and lowered multiple times as needed to ensure the accuracy of the position adjustment of the sealing ring 11 and the sealing ring 12.

[0030] like Figures 9-12 The limiting member 42 located on the right limiting mechanism 4a is provided with a fine-tuning component 7 inside, and there are several fine-tuning components 7. The several fine-tuning components 7 are evenly arranged around the limiting member 42, so that the fine-tuning components 7 can be fully laid in the limiting hole of the right limiting mechanism 4a, thereby helping to fully adjust the position of the sealing ring 11. When the pressing mechanism 3 moves above the left limiting mechanism 4b and works, in the right limiting mechanism 4a, the lifting and lowering of the movable component 6 can simultaneously control several fine-tuning components 7 to reciprocate and apply the same thrust to the sealing ring 11, so that the sealing ring 11 can be adjusted in a simple way, so that the center of the sealing ring 11 is aligned with the center of the limiting hole, thereby helping the pressing mechanism 3 to pick up the sealing ring 11 and improving the efficiency of the feeding operation.

[0031] like Figures 13-20The limiting member 42 located on the left limiting mechanism 4b is equipped with a main adjustment component 8, and there are six main adjustment components 8. The six main adjustment components 8 are evenly arranged around the limiting member 42, which can provide the main power for adjusting the position of the sealing ring 12. When the pressing mechanism 3 moves above the right limiting mechanism 4a and works, the lifting and lowering of the movable component 6 in the left limiting mechanism 4b can control the six main adjustment components 8 to apply the same thrust to the sealing ring 12 at the same time. This allows the sealing ring 12 to be adjusted in a simple way, so that the center of the sealing ring 12 is aligned with the center of the limiting hole. This helps the pressing mechanism 3 to push the sealing ring 11 and the sealing ring 12 to be pressed accurately, thereby improving the efficiency of the pressing operation.

[0032] In summary, the right limit mechanism 4a and the left limit mechanism 4b only require multiple lifting operations to push multiple fine-tuning components 7 or multiple main adjustment components 8 to adjust the position of the sealing ring 11 or sealing ring 12. Compared with the traditional positioning claw, the operation of positioning and adjusting the sealing ring 11 or sealing ring 12 is simpler.

[0033] Example 2, based on Example 1, such as Figure 12 The fine-tuning component 7 includes a fixation tube 71 and a fixation capsule 72, such as Figure 5 , Figure 11 The fixing tube 71 is L-shaped and is fixedly sleeved inside the limiting member 42. One end of the fixing tube 71 is fixedly connected to the limiting cavity, and the other end is fixedly connected to the upper half of the limiting hole, effectively providing a path for the movement of gas in the limiting cavity. A fixing bladder 72 is fixedly connected to the upper half of the wall of the limiting hole corresponding to the position of the fixing tube 71, and the fixing bladder 72 is connected to the limiting member 42 by a horizontal spring. When the limiting ring 43 moves down and compresses the space of the limiting cavity, the gas in the limiting cavity is transferred to the fixing bladder 72 through the fixing tube 71, thereby pushing the fixing bladder 72 to expand and move outward. When the limiting ring 43 moves up... When the space of the stretching limiting cavity is extended, the gas in the fixing bladder 72 is transferred back into the limiting cavity through the fixing tube 71, thereby causing the horizontal spring to drive the fixing bladder 72 to contract and move inward. It should be noted that if the limiting ring 43 is in the lowest position, the expanded fixing bladder 72 will be in contact with the already adjusted sealing ring 11. Therefore, when the pressing mechanism 3 performs the feeding operation, the movable component 6 needs to set the limiting ring 43 in the lowest position to ensure that the fine adjustment component 7 can apply a pushing force to the sealing ring 11 to enhance the placement stability of the sealing ring 11, and to ensure that the fine adjustment component 7 will not affect the feeding operation of the pressing mechanism 3 on the sealing ring 11.

[0034] Example 3, based on Example 2, such as Figure 20 The main control component 8 includes a push tube 81, a push rod 82, a pusher 83, and a steel cable 84, such as Figures 13-20The push tube 81 is T-shaped with a 90-degree rotation, and the lower half of the push tube 81 has an inverted L-shaped push cavity. One end of the push rod 82 is fixedly connected to the bottom end of the limiting ring 43, and the other end of the push rod 82 passes through the upper half of the push tube 81 and is movably sleeved with the vertical inner wall of the push cavity. The push member 83 is movably sleeved with the transverse inner wall of the push cavity. The push cavity area between the bottom end of the push rod 82 and the tail end of the push member 83 is filled with a solution. The bottom end of the push rod 82 and the tail end of the push member 83 are connected by a steel rope 84, thereby utilizing the push... A solution and a steel rope 84 are arranged between the moving rod 82 and the pushing member 83, so that the movement of the moving rod 82 can drive the pushing member 83 to move synchronously. A fixed sleeve is fixedly connected to the transverse inner wall of the pushing cavity near the vertical inner wall, and the steel rope 84 passes through the fixed sleeve, effectively ensuring that the steel rope 84 is always in an L-shape, thereby effectively limiting the movement path of the steel rope 84. In summary, when the limiting ring 43 moves up and down, the moving rod 82 can move vertically within the pushing tube 81. If the moving rod 82 moves down, the pushing member 83 can be pulled into the pushing cavity by the steel rope 84. If the push rod 82 moves upward, the pusher 83 can be pushed outward through the solution. At this time, the head of the pusher 83 contacts the sealing ring 12 and can apply a pushing force to the sealing ring 12 to adjust the position of the sealing ring 12 in the limiting hole. Specifically, after the main adjustment component 8 has adjusted multiple times, when the limiting ring 43 moves to the top position, the head of the pusher 83 moves into the limiting hole of the limiting component 42, and the head of the pusher 83 will come into contact with the adjusted sealing ring 12 to achieve the positioning of the sealing ring 12. When the limiting ring 43 moves down to the lowest position, the head of the pushing component 83 can move to the transverse inner area of ​​the pushing cavity to release the sealing ring 12, making it convenient to pick up the pressed finished product and improve work efficiency. It should be noted that when the pressing mechanism 3 performs the pressing operation, the moving component 6 needs to set the limiting ring 43 to the highest position, so as to ensure that the main adjusting component 8 can apply a pushing force to the sealing ring 12 to enhance the placement stability of the sealing ring 12, and also to ensure that the main adjusting component 8 will not affect the pressing operation of the pressing mechanism 3 on the sealing ring 12.

[0035] Example 4, based on Example 3, such as Figures 13-19 Three sets of buffer rings 5 ​​are fixedly connected to the top of the limiting ring 43, and the center of the three sets of buffer rings 5 ​​is concentric with the center of the limiting ring 43. The setting of multiple sets of buffer rings 43 helps to buffer when the pressure plate 35 impacts the limiting ring 43. Each set of buffer rings 5 ​​is composed of two rubber rings with different cross-sectional shapes. One rubber ring has a right-angled triangle cross-section, and the other rubber ring has a right-angled trapezoid shape. There is a gap hole between the two rubber rings. The shape setting of the buffer ring 5 not only helps to push the sealing ring 11 into the mounting groove of the sealing ring 12, but also helps to quickly and fully restore its own shape.

[0036] like Figures 13-19 The main adjustment component 8 also includes a push bladder 85 and a guide tube 86. The push bladder 85 is fixedly connected between the bottom end of the push rod 82 and the inner bottom end of the push tube 81, and the push bladder 85 is filled with a solution. The lower half of the guide tube 86 is fixedly sleeved with the push rod 82, and the upper half of the guide tube 86 is fixedly sleeved with the limiting ring 43. One end of the guide tube 86 communicates with the inside of the push bladder 85, and the other end of the guide tube 86 is located below the buffer ring 5. A vertical rod is movably sleeved at the port of the guide tube 86 located below the buffer ring 5, and the vertical rod is connected to the inner wall of the guide tube through a vertical spring. The vertical rod is located below the gap hole between the two rubber rings. When the push rod 82 moves up and down reciprocally, it effectively squeezes the solution in the push bladder 85, pushes the solution into the guide tube 86 and pushes the vertical rod upward, so that the vertical rod moves in the gap hole and pushes the buffer ring 5 vertically, so that the buffer ring 5 can adjust its shape in a timely and sufficient manner, shorten the recovery time of the buffer ring, and ensure the normal use of the buffer ring next time.

[0037] Example 5, based on Example 4, provides a pressing device for the production and processing of mechanical seals, further comprising a moving mechanism 2 and a pressing mechanism 3, such as... Figures 1-2 A moving mechanism 2 is fixedly installed on the rear side of the top of the workbench 1, and a pressing mechanism 3 is movably installed on the front side of the moving mechanism 2. The moving mechanism 2 can drive the pressing mechanism 3 to move horizontally, and the pressing mechanism 3 can move vertically, so that the sealing ring 11 is picked up and fully pressed into the sealing ring 12. Specifically: like Figures 5-6 The moving mechanism 2 includes a moving frame 21 and a moving shaft 22. The moving frame 21 is fixedly installed on the rear side of the top of the workbench 1, and a moving groove is provided on the moving frame 21. The moving shaft 22 is movably installed in the moving groove of the moving frame 21, and a motor is movably connected to one end of the moving shaft 22 that passes through the moving frame 21, so that the motor can drive the moving shaft 22 to rotate, thereby providing power for the horizontal movement of the pressing mechanism 3.

[0038] like Figures 5-7The pressing mechanism 3 includes a fixed frame 31, a fixed cylinder 32, a fixed column 33, a lifting cylinder assembly 34, a pressure plate 35, an outer positioning ring 36, and an inner positioning ring 37. The rear side of the fixed frame 31 is movably engaged with the moving groove of the moving frame 21, and the rear side of the fixed frame 31 is threadedly connected to the moving shaft 22. When the moving shaft 22 rotates, it can drive the fixed frame 31 to move horizontally along the moving groove. The fixed cylinder 32 is fixedly sleeved in the middle of the front side of the fixed frame 31. The bottom end of the fixed cylinder 32 is fixedly sleeved with one end of the fixed column 33. The fixed column 33 is composed of a large cylinder, a large frustum, a small cylinder, and a small frustum, and the dimensions of the fixed column 33 gradually decrease from top to bottom. The diameter of the large cylinder is adapted to the inner diameter of the sealing ring 11. The diameter of the small cylinder is adapted to the inner diameter of the sealing ring 12, allowing the fixing post 33 to be smoothly inserted into the right limiting mechanism 4a and the left limiting mechanism 4b. This facilitates both the alignment and loading of the sealing ring 11 and the alignment and pressing of the sealing ring 12. A lifting cylinder assembly 34 is fixedly sleeved within the fixing frame 31 located in front of and behind the fixing post 33. The bottom end of the lifting cylinder assembly 34 is fixedly connected to the top end of the pressure plate 35. A circular hole is provided in the middle of the pressure plate 35, through which the fixing post 33 can pass. The lifting cylinder assembly 34 can drive the pressure plate 35 downwards, thereby pushing the sealing ring 11 downwards and disengaging it from the fixing post 33, allowing the sealing ring 11 to transfer and press onto the mounting groove of the sealing ring 12. Figure 3 The bottom end of the pressure plate 35 is movably connected to an outer positioning ring 36 and an inner positioning ring 37, which are concentrically arranged. The inner positioning ring 37 is located inside the outer positioning ring 36, and the gap between the outer positioning ring 36 and the inner positioning ring 37 corresponds to the position of the innermost buffer ring 5. Thus, when the pressure plate 35 is pressed down, the buffer ring 5 can separate the outer positioning ring 36 and the inner positioning ring 37. The inner positioning ring 37 changes direction due to the inclined design of the buffer ring 5, effectively applying a pushing force to the sealing ring 11 towards the sealing ring 12, further ensuring that the sealing ring 11 is completely pressed into the mounting groove of the sealing ring 12. When the inner positioning ring 37 is not squeezed or pushed, the inner positioning ring 37 does not fit with the sealing ring 11, effectively ensuring that the inner positioning ring 37 does not affect the sealing ring 11, thereby ensuring that the sealing ring 11 can be fully pushed by the pressure plate 35. The outer positioning ring 36 and the inner positioning ring 37 are made of rubber, which is convenient for deformation to achieve different functions such as buffering.

[0039] The working principle of the method of using this invention is as follows: First, the sealing ring 11 is inserted into the limiting hole of the right limiting mechanism 4a. Then, the movable component 6 on the right limiting mechanism 4a is activated, causing the movable component 6 to reciprocate and drive the limiting ring 43 to move up and down. This effectively controls multiple fine-tuning components 7 to synchronously and reciprocally apply the same thrust to the sealing ring 11. That is, when the limiting ring 43 moves down, the fixing bladder 72 expands under the action of gas and pushes it to adjust the position of the sealing ring 11 to be aligned with the center of the limiting hole. When the limiting ring 43 moves up, the fixing bladder 72 contracts under the action of the horizontal spring and does not contact the sealing ring 11. This process is repeated to continuously adjust the position of the sealing ring 11 until the center of the sealing ring 11 is aligned with the center of the limiting hole. After that, the movable component 6 stops moving and the limiting ring 43 is controlled to be in the lowest position, thus preparing for the loading operation of the sealing ring 11. In summary, the right limiting mechanism 4a can realize the adjustment of the position of the sealing ring 11 in the limiting hole through a simple lifting operation, effectively simplifying the steps of adjusting the position of the sealing ring 11 in the limiting hole, reducing time waste, improving processing efficiency, and ensuring the quality of the finished product.

[0040] Next, when the moving mechanism 2 pushes the pressing mechanism 3 to move above the right limit mechanism 4a, the fixing cylinder 32 is activated to push the fixing column 33 downward, so that the lower end of the fixing column 33 is inserted into the limit hole and the sealing ring 11 is fitted into the outer wall of the fixing column 33. Then the fixing cylinder 32 is activated to push the fixing column 33 upward, thereby completing the feeding operation of the sealing ring 11.

[0041] Simultaneously, the sealing ring 12 is inserted into the limiting hole of the left limiting mechanism 4b, and then the movable component 6 on the left limiting mechanism 4b is activated, causing the movable component 6 to reciprocate and drive the limiting ring 43 to move up and down. This effectively controls the six main adjusting components 8 to simultaneously apply the same thrust to the sealing ring 12. That is, when the limiting ring 43 moves upward, the push rod 82 is pushed by the solution and drives the pusher 83 to move outward, thus applying a thrust to the sealing ring 12. Moreover, the push distances of the six pushers 83 are equal, effectively adjusting the position of the sealing ring 12. When the limiting ring 43 moves downward, the push rod 82 is pulled by the steel rope 84 and drives the pusher 83 to move inward, thus not applying a thrust to the sealing ring 12. This process is repeated, and the position of the sealing ring 12 is continuously adjusted under the combined action of the main adjusting components 8 until the center of the sealing ring 12 is aligned with the center of the limiting hole. After the center is aligned, the moving component 6 stops moving, and the control limit ring 43 is in the highest position, thus preparing for the pressing operation of the sealing ring 12 and the sealing ring 11. In summary, the left limit mechanism 4b can realize the adjustment of the position of the sealing ring 12 in the limit hole through a simple lifting operation, effectively simplifying the steps of adjusting the position of the sealing ring 12 in the limit hole, reducing time waste, improving processing efficiency, and ensuring the quality of finished products. In addition, during the reciprocating movement of the push rod 82, the solution in the push bladder 85 is effectively squeezed, causing the solution to move back and forth into the guide tube 86, thereby pushing the vertical rod to move upward and within the spacer hole. This helps to fully push the buffer ring 5 vertically, allowing the buffer ring 5 to adjust its shape in a timely and sufficient manner, shortening the recovery time of the buffer ring 5, and ensuring the normal use of the buffer ring 5 during the pressing stage.

[0042] Next, when the moving mechanism 2 pushes the pressing mechanism 3 to move above the left limiting mechanism 4b, the fixing cylinder 32 is activated to push the fixing column 33 downward, causing it to move the sealing ring 11 and approach the sealing ring 12. Then, the lifting cylinder assembly 34 is activated to push the pressure plate 35 downward, so that the pressure plate 35 applies a downward pushing force to the sealing ring 11, thereby pressing the sealing ring 11 into the mounting groove of the sealing ring 12. At the same time, as the pressure plate 35 and the limiting ring 43 move towards each other, the inner positioning ring 37 changes direction under the limitation of the buffer ring 5, causing the inner positioning ring 37 to apply a pushing force to the sealing ring 11 towards the sealing ring 12, further ensuring that the sealing ring 11 is completely pressed into the mounting groove of the sealing ring 12. After that, the fixing cylinder 32 is activated to push the fixing column 33 upward, thereby completing the pressing operation of the sealing ring 11 and the sealing ring 12. In addition, during this process, the right limiting mechanism 4a simultaneously performs the placement and adjustment operation of the sealing ring 11.

[0043] Finally, when the moving mechanism 2 pushes the pressing mechanism 3 to move above the right limit mechanism 4a again, the moving component 6 in the left limit mechanism 4b is controlled to push the limit ring 43 down to the lowest end. Then the pressed finished product is taken out and a new sealing ring 12 is placed for the next processing.
