Description

Technical Field

[0001] This invention relates to the field of sealing ring installation technology, specifically to a sealing ring feeding device for an air compressor. Background Technology

[0002] There are two types of air compressor seals: O-rings and lip seals. O-rings are one of the most common types of seals in air compressors. They have a circular cross-section and are simple in structure and easy to install. O-rings can provide good sealing performance in both static and dynamic conditions. Between the piston and cylinder wall of the air compressor, the seal can prevent compressed air from leaking from the gaps on both sides of the piston, ensuring effective air compression and transmission.

[0003] Air compressor seals are typically installed on piston rods manually by stretching them to ensure accuracy. However, manual stretching makes it difficult to guarantee uniform stretching. Operators may apply excessive force to certain areas, causing overstretching. During manual stretching, the seal may come into contact with the operator's tools or fingers. Since the seal material is usually soft and easily scratched by sharp objects, manually stretching and installing the seal on the piston rod is a relatively slow process, especially for inexperienced operators. This can take a considerable amount of time, significantly reducing work efficiency in large-scale production or when frequent seal replacements are required. Summary of the Invention

[0004] The purpose of this invention is to provide an air compressor seal ring feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an air compressor seal ring feeding device, comprising a mounting base and a piston rod conveyor belt movably mounted on the mounting base. A gantry mounting frame is fixedly mounted on the top of the mounting base, and a first electric push rod is fixedly mounted on the top of the gantry mounting frame. An assembly frame is fixedly mounted on the bottom end of the piston rod of the first electric push rod. A swing arm is movably mounted on the bottom end of the assembly frame via a movable shaft. A stepper motor is fixedly mounted on the assembly frame at a position corresponding to the movable shaft. The output shaft of the stepper motor is fixedly connected to the movable shaft between the assembly frame and the swing arm. A lifting mounting seat is fixedly mounted on the piston rod of the swing arm. Four adjustable inclined support plates are rotatably connected to the lifting mounting seat. Four guide support rods are fixedly installed at the end of the boom away from the assembly frame. Guide balls are fixedly installed at the end of the guide support rods away from the swing arm. The adjustable inclined plate has guide grooves corresponding to the shape of the guide balls. The guide balls are movably engaged in the guide grooves. The side wall of the lifting mounting seat is fixedly installed with an annular spring piece through a fixed seat. The annular spring piece is movably engaged in the adjustable inclined plate, and a fixing collar is fixedly installed on the annular spring piece. The fixing collar is supported at a corresponding position on the outer wall of the adjustable inclined plate. A circular mounting buckle is fixedly installed at the top of the adjustable inclined plate. A rotating rod is rotatably connected inside the circular mounting buckle. A limit rotating plate is fixedly installed on the outer wall of the rotating rod, and a fixing cap is threadedly connected to the rotating rod.

[0006] Preferably, the fixing cap and the circular mounting buckle are provided with anti-slip texture on the side near the fixing cap.

[0007] Preferably, a protective pull-out cloth is provided on the side of the limiting rotating plate near the adjustable inclined brace plate. The protective pull-out cloth is movably inserted into the adjustable inclined brace plate, and the protective pull-out cloth is located at the connection position between the limiting rotating plate and the adjustable inclined brace plate.

[0008] Preferably, an extension support strip is fixedly installed on the outer wall of the lifting mounting base at the position corresponding to the adjustable diagonal brace plate.

[0009] Preferably, an auxiliary mounting bracket is fixedly installed on the top of the mounting base, and an inclined mounting platform is fixedly installed on the auxiliary mounting bracket. A second electric push rod is movably installed on the top of the inclined mounting platform through a connecting plate. A sealing ring pressure plate is fixedly installed at the bottom end of the piston rod of the second electric push rod. A feeding cylinder is fixedly installed at the bottom of the inclined mounting platform. Multiple sealing rings are provided inside the feeding cylinder. A third electric push rod and a fourth electric push rod are fixedly installed on the feeding cylinder. A semi-ring limiting plate that is movably inserted into the feeding cylinder is fixedly installed on the piston rod of the fourth electric push rod. An insertable fixing component is fixedly installed on the piston rod of the third electric push rod. The insertable fixing component and the semi-ring limiting plate are located above and below the lowest sealing ring, respectively.

[0010] Preferably, the feed cylinder is provided with a cavity corresponding to the shape of the sealing ring.

[0011] Preferably, a limiting end plate is fixedly installed inside the inclined mounting platform, and a sliding seat is fixedly installed at the bottom of the connecting plate. The sliding seat is movably engaged inside the inclined mounting platform, and the bottom of the sliding seat is in rolling connection with the bottom of the inner wall of the inclined mounting platform.

[0012] Preferably, the upper surface of the inclined mounting platform is provided with a dovetail groove corresponding to the shape of the sliding seat.

[0013] Preferably, the feeding cylinder and the swing arm in the unfolded state are arranged parallel to each other.

[0014] Preferably, the feed cylinder has a through groove at the position corresponding to the insertion-type fixing member and the semi-ring limiting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. After the sealing ring falls onto the structure composed of adjustable inclined braces and limiting rotating plates, the structure unfolds like flower petals, causing the sealing ring to deform. The sealing ring is pre-fitted onto the piston rod. The structure then resets, restoring the sealing ring to its pre-deformed shape. The piston rod of the first electric push rod also pushes the assembly frame for movement compensation. The re-deformed sealing ring is then fitted onto the piston rod. The structure composed of adjustable inclined braces and limiting rotating plates provides accurate positioning guidance for the sealing ring. During installation, the sealing ring may be difficult to fit accurately due to its elasticity and flexibility. The adjustable bracing plates and limiting rotating plates on the piston rod act like guide rails, helping the sealing ring deform and fit in the correct direction. This makes it easier to align the sealing ring with the piston rod and reduces the hassle of repeated adjustments due to positional deviations during installation. During installation, the sealing ring is easily damaged by excessive stretching, twisting, or scratching against the piston rod surface. The structure composed of multiple adjustable bracing plates and limiting rotating plates makes the deformation process of the sealing ring more uniform and gradual. They prevent the sealing ring from being overstretched or compressed at a certain point, thus avoiding localized damage or tearing.

[0017] 2. After the sealing ring contacts the semi-ring limiting plate, the piston rod of the third electric push rod pushes the insert-type fixing component to move. The insert-type fixing component is inserted between the bottom sealing ring and the sealing ring above it, thus fixing the sealing ring above the bottom sealing ring. The semi-ring limiting plate no longer applies a fixing effect to the sealing ring, and the sealing ring falls freely due to gravity. The existence of multiple limiting structures can precisely control the position of the sealing ring as it falls, ensuring that it lands accurately at the position of the piston rod. On an automated assembly line, the precise limiting structure allows the sealing ring installation process to coordinate efficiently with other production processes, improving overall production efficiency.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0034] Please see Figures 1 to 14This invention provides a technical solution: an air compressor seal ring feeding device, including a mounting base 1 and a piston rod conveyor belt 2 movably mounted on the mounting base 1. A piston rod for mounting a seal ring 27 is placed on the piston rod conveyor belt 2. A gantry mounting frame 3 is fixedly mounted on the top of the mounting base 1. The gantry mounting frame 3 is used to assist in the installation of the instrument, and it is hollowed out to reduce its weight, thereby reducing the weight of the mounting base 1 and related structures on the mounting base 1, thus improving the convenience of instrument installation and handling. A first electric push rod 4 is fixedly mounted on the top of the gantry mounting frame 3, and an assembly frame 5 is fixedly mounted on the bottom end of the piston rod of the first electric push rod 4. The assembly frame 5 is driven by the lifting and lowering of the piston rod of the first electric push rod 4. The lifting and lowering of the assembly frame 5 drives the lifting and lowering of the structure installed on the assembly frame 5, so as to facilitate the movement of the sealing ring 27 and the installation of the auxiliary sealing ring 27 on the structure of the assembly frame 5. A swing arm 6 is movably mounted on the bottom end of the assembly frame 5 via a movable shaft. A movable shaft is provided at the connection position between the assembly frame 5 and the swing arm 6 to ensure the normal rotation of the swing arm 6 on the assembly frame 5. A stepper motor 7 is fixedly mounted on the assembly frame 5 at the position corresponding to the movable shaft. The output shaft of the stepper motor 7 is fixedly connected to the movable shaft between the assembly frame 5 and the swing arm 6. The rotation of the output shaft of the stepper motor 7 drives the rotation of the swing arm 6 to ensure that the swing arm 6 and the unloading cylinder 26 are parallel to each other, and to ensure that the sealing ring 27 in the unloading cylinder 26 can fall onto the swing arm 6. On the structure related to the fixed sealing ring 27, a lifting mounting seat 8 is fixedly installed on the piston rod of the swing arm 6. The lifting and lowering of the lifting mounting seat 8 drives the related structure on the lifting mounting seat 8 to rise and fall. A slot is opened on the lifting mounting seat 8 at the position of the guide support rod 10 to ensure the normal rising and falling of the guide support rod 10. The opening of the slot on the lifting mounting seat 8 does not affect the movement of the guide support rod 10. Four adjustable inclined support plates 9 are rotatably connected to the lifting mounting seat 8. The adjustable inclined support plates 9 are provided with movable shafts at the positions of the lifting mounting seat 8. A fixed sleeve is provided on the top of the lifting mounting seat 8 at the position corresponding to the adjustable inclined support plates 9, and to ensure the normal rotation of the adjustable inclined support plates 9 and the lifting mounting seat 8. The adjustable inclined brace 9 rotates around the lifting mounting base 8 to support the sealing ring 27, ensuring the deformation of the sealing ring 27. Four guide support rods 10 are fixedly installed at the end of the swing arm 6 away from the assembly frame 5, and guide balls 11 are fixedly installed at the end of the guide support rods 10 away from the swing arm 6. The adjustable inclined brace 9 has guide grooves 901 corresponding to the shape of the guide balls 11. The guide balls 11 are movably engaged in the guide grooves 901. The piston rod of the swing arm 6 drives the lifting mounting base 8 to move. During the movement of the lifting mounting base 8, the guide balls 11 at the top of the guide support rods 10 move in the guide grooves 901 on the adjustable inclined brace 9. The guide support rods 10 consist of a vertical part and an inclined part.To ensure that when the adjustable inclined plate 9 rotates, the angle of rotation of the adjustable inclined plate 9 is sufficient to open the sealing ring 27, the side wall of the lifting mounting base 8 is fixedly mounted with an annular spring 12 via a fixed seat 13. The annular spring 12 is movably engaged with the adjustable inclined plate 9, and a fixed collar 14 is fixedly mounted on the annular spring 12. The fixed collar 14 is supported at the corresponding position on the outer wall of the adjustable inclined plate 9. The annular spring 12 is made of deformable metal. Due to the design that the annular spring 12 can deform, when the annular spring 12 is subjected to the thrust during the rotation of the adjustable inclined plate 9, the fixed collar 14 transmits the thrust to the annular spring 12, causing the annular spring 12 to deform. After the annular spring 12 deforms, the guide support rod 10 no longer applies thrust to the adjustable inclined plate 9. Instead, when it retracts, under the action of the reverse thrust of the annular spring 12, the adjustable inclined plate 9 rotates around the lifting mounting base 8. The mounting base 8 rotates in the opposite direction to reset, allowing the sealing ring 27 to detach from the structure composed of multiple adjustable inclined braces 9. A circular mounting buckle 15 is fixedly installed at the top of each adjustable inclined brace 9. A rotating rod 16 is rotatably connected inside the circular mounting buckle 15, which assists in the installation of the rotating rod 16. A limiting rotating plate 17 is fixedly installed on the rotating rod 16. The V-shaped structure formed by the limiting rotating plate 17 and the adjustable inclined braces 9 limits the deformation of the sealing ring 27, preventing it from detaching from the structure. The limiting rotating plate 17 is fixedly installed on the outer wall of the rotating rod 16, and a fixing cap 18 is threaded onto the rotating rod 16. By turning the fixing cap 18, pressure is applied to the circular mounting buckle 15, thus fixing the limiting rotating plate 17 after rotation. Changing the angle of the V-shaped structure formed by the limiting rotating plate 17 and the adjustable inclined braces 9 achieves a better limiting effect or facilitates the detachment of the sealing ring 27.

[0035] Anti-slip textures are provided on the near sides of the fixed screw cap 18 and the circular mounting buckle 15. After the fixed screw cap 18 and the circular mounting buckle 15 come into contact, friction is generated between the fixed screw cap 18 and the circular mounting buckle 15. The fixed plate 17 is fixed by the friction between the fixed screw cap 18 and the circular mounting buckle 15.

[0036] A protective pull-out cloth 19 is provided on the side of the limiting rotating plate 17 near the adjustable inclined support plate 9. The protective pull-out cloth 19 is movably inserted into the adjustable inclined support plate 9, and the protective pull-out cloth 19 is located at the connection position between the limiting rotating plate 17 and the adjustable inclined support plate 9. The protective pull-out cloth 19 covers the connection position between the limiting rotating plate 17 and the adjustable inclined support plate 9 to prevent the position from being exposed, so as to ensure the fixing effect of the sealing ring 27 at the connection position between the adjustable inclined support plate 9 and the limiting rotating plate 17. At the same time, it protects the sealing ring 27 from the pressure of sharp positions, preventing the sealing ring 27 from being damaged to the outer surface of the sealing ring 27 and affecting the sealing effect of the sealing ring 27. In addition, the protective pull-out cloth 19 is large in size, and the excess part can be pulled out from the adjustable inclined support plate 9 to accommodate the rotation of the limiting rotating plate 17 around the adjustable inclined support plate 9.

[0037] An extension support bar 20 is fixedly installed on the outer wall of the lifting mounting base 8 at the position corresponding to the adjustable inclined brace plate 9. The extension support bar 20 is an additional part to accommodate larger sealing rings 27, so as to achieve the effect of accommodating the installation of sealing rings 27 of different sizes.

[0038] An auxiliary mounting bracket 21 is fixedly mounted on the top of the mounting base 1. An inclined mounting platform 22 is fixedly mounted on the auxiliary mounting bracket 21. The inclined mounting platform 22 is inclined, and a trapezoidal groove is formed on its upper surface to allow movement of the inclined mounting platform 22 and the connecting plate 23 within it. A second electric push rod 24 is movably mounted on the top of the inclined mounting platform 22 via the connecting plate 23. A sealing ring pressure plate 25 is fixedly mounted at the bottom end of the piston rod of the second electric push rod 24. The piston rod of the second electric push rod 24 pushes the sealing ring pressure plate 25 to move, applying pressure to multiple sealing rings 27 through the sealing ring pressure plate 25. This ensures the effective movement of the sealing rings 27 within the feed cylinder 26 and prevents insufficient power for the sealing rings 27 to move solely by gravity. A feed cylinder 26 is fixedly mounted at the bottom of the inclined mounting platform 22, and multiple sealing rings 27 are disposed within the feed cylinder 26. 7. A third electric push rod 28 and a fourth electric push rod 29 are fixedly installed on the feed cylinder 26. A semi-ring limiting plate 30 that is movably inserted into the feed cylinder 26 is fixedly installed on the piston rod of the fourth electric push rod 29. An insertable fixing part 31 is fixedly installed on the piston rod of the third electric push rod 28. The insertable fixing part 31 and the semi-ring limiting plate 30 are located above and below the lowest sealing ring 27, respectively. The insertable fixing part 31 fixed on the piston rod of the third electric push rod 28 consists of a connecting part and an inserting part. The end of the inserting part is a relatively sharp part to ensure that the insertable fixing part 31 can be inserted between multiple sealing rings 27. The insertable fixing part 31 blocks multiple sealing rings 27. The semi-ring limiting plate 30 blocks the lowest sealing ring 27. After blocking, the sealing ring 27 is released and allowed to fall.

[0039] The feed cylinder 26 has a cavity corresponding to the shape of the sealing ring 27 to ensure the guiding effect of multiple sealing rings 27.

[0040] A limiting end plate 33 is fixedly installed inside the inclined mounting platform 22. A sliding seat 32 is fixedly installed at the bottom of the connecting plate 23. The sliding seat 32 is movably engaged inside the inclined mounting platform 22. The bottom of the sliding seat 32 is in rolling connection with the bottom of the inner wall of the inclined mounting platform 22. The limiting end plate 33 has a limiting effect to prevent the sliding seat 32 from moving out of position. Rollers are provided on the sliding seat 32 near the bottom of the inclined mounting platform 22 to realize the rolling connection between the sliding seat 32 and the inclined mounting platform 22.

[0041] The upper surface of the inclined mounting platform 22 is provided with a dovetail groove corresponding to the shape of the sliding seat 32, which ensures the movement between the sliding seat 32 and the inclined mounting platform 22, as well as the fixing effect of the inclined mounting platform 22 on the sliding seat 32.

[0042] The feeding cylinder 26 and the swing arm 6 in the unfolded state are arranged parallel to each other. The feeding cylinder 26 and the swing arm 6 are parallel to each other, and the structure composed of the adjustable inclined support plate 9 and the limiting rotating plate 17 is located in the direction of the sealing ring 27 falling, so as to ensure that the sealing ring 27 is stably fitted outside the structure composed of the adjustable inclined support plate 9 and the limiting rotating plate 17 after falling.

[0043] The feed cylinder 26 has through slots at the positions of the insert-type fixing member 31 and the semi-ring limiting plate 30 to ensure the extension and retraction stroke of the semi-ring limiting plate 30 and the insert-type fixing member 31.

[0044] Working principle:

[0045] Step 1: After the piston rod is conveyed on the piston rod conveyor belt 2 to a position directly below the assembly frame 5, it stops. The piston rod of the second electric push rod 24 pushes the sealing ring pressure plate 25 to move. The sealing ring pressure plate 25 is located inside the feed cylinder 26 and contacts the sealing ring 27. The sealing ring pressure plate 25 applies pressure to the sealing ring 27, causing the sealing ring 27 to move within the feed cylinder 26. After the sealing ring 27 contacts the semi-ring limiting plate 30, the piston rod of the third electric push rod 28 pushes the insert-type fixing member 31 to move. The insert-type fixing member 31 is inserted between the lowermost sealing ring 27 and the sealing ring 27 above it, realizing... With the sealing ring 27 fixed above the bottom sealing ring 27, the piston rod of the fourth electric push rod 29 retracts, and the semi-ring limiting plate 30 no longer applies a fixing effect to the sealing ring 27. The sealing ring 27 falls freely to the ground due to gravity, landing outside the structure composed of the adjustable inclined brace plate 9 and the limiting rotating plate 17. At this time, the piston rod of the fourth electric push rod 29 pushes the semi-ring limiting plate 30 to reset, and the piston rod of the third electric push rod 28 also pushes the insert fixing member 31 to retract. After the insert fixing member 31 retracts, the piston rod of the third electric push rod 28 pushes multiple sealing rings 27 to continue moving. Then, this operation is repeated to control the movement of the sealing ring 27.

[0046] Step 2: After the sealing rings 27 in the feed cylinder 26 are used up, additional sealing rings 27 need to be added to the feed cylinder 26. When adding sealing rings 27, the second electric push rod 24 needs to be operated to retract the sealing ring pressure plate 25. The sealing ring pressure plate 25 is no longer located in the feed cylinder 26. The structure composed of the second electric push rod 24, the connecting plate 23 and the sliding seat 32 is pushed to move in the inclined mounting platform 22. The feeding port above the feed cylinder 26 is exposed, and multiple sealing rings 27 are added to the feed cylinder 26 together. Then, the structure composed of the second electric push rod 24, the connecting plate 23 and the sliding seat 32 is operated to reset.

[0047] Step 3: After the sealing ring 27 rests on the structure composed of the adjustable inclined brace 9 and the limiting rotating plate 17, the piston rod of the swing arm 6 pulls the lifting mounting base 8 to move closer to the swing arm 6. The guide ball 11 on the end of the guide support rod 10 moves in the guide groove 901. The movement of the guide ball 11 in the guide groove 901 applies pressure to the adjustable inclined brace 9. After being subjected to pressure, the adjustable inclined brace 9 rotates around the lifting mounting base. As the adjustable brace plate 9 rotates around the lifting mounting base 8, it drives the fixed collar 14 to move, causing the fixed collar 14 to apply pressure to the annular spring 12, thereby driving the annular spring 12 to deform. After the annular spring 12 deforms, it generates a reverse elastic force. The structure composed of multiple adjustable brace plates 9 and the limiting rotating plate 17 unfolds like petals, applying pressure to the inner wall of the sealing ring 27, causing the sealing ring 27 to deform. The sealing ring 27 is located on the adjustable brace plate. At the connection point between the limiting rotating plate 17 and the adjustable inclined plate 9, the deformed sealing ring 27 is fixed at the connection point between the limiting rotating plate 17 and the adjustable inclined plate 9, and contacts the protective pull-out cloth 19. Then, the stepper motor 7 is operated, and the swing arm 6 rotates around the assembly frame 5, so that the assembly frame 5 and the adjustable inclined plate 9 are parallel. The sealing ring 27 rotates to the top of the piston rod, and the piston rod of the first electric push rod 4 drives the sealing ring 27 to descend. The sealing ring 27 is pre-fitted on the outside of the piston rod. The piston rod of the swing arm 6 drives the lifting mounting seat 8 to move away from the swing arm 6. The guide ball 11 moves in the opposite direction in the guide groove 901. Under the action of the reverse elastic force of the annular spring 12, the structure composed of multiple adjustable inclined plates 9 is reset, and the sealing ring 27 returns to its shape before deformation. At the same time, the piston rod of the first electric push rod 4 also pushes the assembly frame 5 to perform movement compensation to ensure that the position of the sealing ring 27 does not change. The deformed sealing ring 27 is fitted on the piston rod. After the sealing ring 27 is fitted, the swing arm 6 is reset.

[0048] Step 4: Adjust the limiting rotating plate 17 so that the limiting rotating plate 17 drives the rotating rod 16 to rotate within the circular mounting buckle 15, changing the angle of the structure composed of the limiting rotating plate 17 and the adjustable diagonal brace 9. After the angle adjustment is completed, turn the fixing cap 18 so that the fixing cap 18 contacts the circular mounting buckle 15, thereby fixing the adjusted limiting rotating plate 17 and changing the angle between the adjustable diagonal brace 9 and the limiting rotating plate 17 to provide support at different angles.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
