Description

Technical Field

[0001] The invention relates to the technical field of sealing ring installation, in particular to a sealing ring feeding device for an air compressor. Background Art

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

[0003] The seal ring of the air compressor is installed on the piston rod by manual stretching to ensure the accuracy of the seal ring installation. However, it is difficult to ensure the uniformity of the stretching when the seal ring is manually stretched on the piston rod. The operator may apply too much force to a certain local area, causing the part to be overstretched. During the manual stretching process, the seal ring may come into contact with the operator's tools or fingers. Since the seal ring material is usually soft and easily scratched by sharp objects, it is a relatively slow process to manually stretch the seal ring and put it on the piston rod. Especially for inexperienced operators, it may take a long time to complete the installation. This will greatly reduce work efficiency in large-scale production or when the seal ring needs to be replaced frequently. Summary of the invention

A limited rotating plate is fixedly installed on the outer wall of the rotating rod, and a fixed screw cap is threadedly connected on the rotating rod.

[0006] Preferably, anti-slip grooves are provided on the proximal sides of the fixed screw cap and the circular mounting buckle.

[0007] Preferably, a protective pull-out cloth is provided on one side of the limit rotating plate close to the adjustable diagonal support plate, the protective pull-out cloth is movably plugged into the adjustable diagonal support plate, and the protective pull-out cloth is located at the connection position between the limit rotating plate and the adjustable diagonal support plate.

[0010] Preferably, a cavity corresponding to the shape of the sealing ring is provided in the discharge barrel.

[0011] Preferably, a limiting end plate is fixedly installed in the inclined mounting platform, a sliding seat is fixedly installed at the bottom of the connecting plate, the sliding seat is movably engaged in the inclined mounting platform, and the bottom of the sliding seat is rollingly connected to the bottom of the inner wall of the inclined mounting platform.

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

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

[0014] Preferably, the lower barrel is provided with a through groove at a position corresponding to the inserted fixing piece and the semi-ring limiting plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. After the sealing ring falls on the structure composed of the adjustable diagonal support plate and the limit rotating plate, the structure composed of multiple adjustable diagonal support plates and the limit rotating plate unfolds like a petal, driving the sealing ring to deform. The sealing ring is pre-set outside the piston rod, and the structure composed of multiple adjustable diagonal support plates is reset. The sealing ring recovers its shape before deformation. The piston rod of the first electric push rod also pushes the assembly frame to move and compensate. The sealing ring after the deformation is restored is sleeved on the piston rod. The structure composed of multiple adjustable diagonal support plates and the limit rotating plate can provide accurate positioning guidance for the sealing ring. During the installation process, the sealing ring may be difficult to accurately fit due to its own elasticity and softness. At the appropriate position on the piston rod, the structure composed of the adjustable diagonal support plate and the limit rotating plate is like a guide rail, which can help the sealing ring to deform and fit in the correct direction, making it easier for the sealing ring to align with the piston rod and reducing the trouble of repeated adjustments due to position deviation during installation. During the installation process, the sealing ring can easily be damaged due to excessive stretching, twisting or scratching on the surface of the piston rod. The structure composed of multiple adjustable diagonal support plates and limit rotating plates can make the deformation process of the sealing ring more uniform and smooth. They can prevent the sealing ring from being over-stretched or compressed at a certain point, thereby avoiding local damage, tearing, etc.

[0017] 2. After the sealing ring contacts the semi-ring limit plate, the piston rod of the third electric push rod pushes the inserted fixing part to move, and the inserted fixing part is inserted between the lowest sealing ring and the sealing ring above it to fix the sealing ring above the lowest sealing ring. The semi-ring limit plate no longer exerts a fixing effect on the sealing ring, and the sealing ring falls freely due to gravity. The presence of multiple limiting structures can accurately control the falling position of the sealing ring so that it falls accurately on the position of the piston rod. On the automated assembly line, the precise limiting structure can make the installation process of the sealing ring efficiently cooperate with other production links, thereby improving the overall production efficiency.

The bottom end of the assembly rack 5 is movably installed with a swing arm 6 through a movable shaft. A movable shaft is provided at the connection position of the assembly rack 5 and the swing arm 6 to ensure the normal rotation of the swing arm 6 on the assembly rack 5. A stepper motor 7 is fixedly installed at the position corresponding to the movable shaft on the assembly rack 5. The output shaft of the stepper motor 7 is fixedly connected to the movable shaft between the assembly rack 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 discharge barrel 26 are parallel to each other, so as to ensure that the sealing ring 27 in the discharge barrel 26 can fall on the swing arm 6. On the related structure of the fixed sealing ring 27, a lifting mounting seat 8 is fixedly installed on the piston rod of the swing arm 6, and the lifting and lowering of the lifting mounting seat 8 drives the related structures on the lifting mounting seat 8 to rise and fall. A slot is provided on the lifting mounting seat 8 at the position of the guide support rod 10 to ensure the normal lifting and lowering 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 diagonal support plates 9 are rotatably connected to the lifting mounting seat 8. The adjustable diagonal support plates 9 are provided with movable shafts at the positions of the lifting mounting seat 8. A fixed sleeve is provided at the position of the adjustable diagonal support plates 9 at the top of the lifting mounting seat 8, and the normal rotation of the adjustable diagonal support plates 9 and the lifting mounting seat 8 is ensured through multiple adjustable The adjustable diagonal support plate 9 rotates around the lifting mounting seat 8 to realize the support of the sealing ring 27 by the adjustable diagonal support plate 9 to ensure the deformation of the sealing ring 27. Four guide support rods 10 are fixedly installed on the end of the swing arm 6 away from the assembly frame 5. A guide ball 11 is fixedly installed on the end of the guide support rod 10 away from the swing arm 6. A guide groove 901 corresponding to the shape of the guide ball 11 is opened on the adjustable diagonal support plate 9. The guide ball 11 is movably engaged in the guide groove 901. The lifting mounting seat 8 is driven to move by the piston rod of the swing arm 6. During the movement of the lifting mounting seat 8, the guide ball 11 on the top of the guide support rod 10 moves in the guide groove 901 on the adjustable diagonal support plate 9. The guide support rod 10 consists of a vertical part and an inclined part.The guide support rod 10 is a structure that supports the adjustable diagonal support plate 9 to rotate, and the adjustable diagonal support plate 9 rotates at an angle sufficient to open the sealing ring 27. The side wall of the lifting mounting seat 8 is fixedly installed with an annular spring piece 12 through a fixed seat 13. The annular spring piece 12 is movably engaged with the adjustable diagonal support plate 9, and a fixed collar 14 is fixedly installed on the annular spring piece 12. The fixed collar 14 is supported at a corresponding position on the outer wall of the adjustable diagonal support plate 9. The annular spring piece 12 is made of metal with deformation ability. The annular spring piece 12 can be deformed by the design that the annular spring piece 12 is deformed. When the annular spring piece 12 is subjected to the thrust during the rotation of the adjustable diagonal support plate 9, the fixed collar 14 transmits the thrust to the annular spring piece 12, driving the annular spring piece 12 to deform. After the annular spring piece 12 is deformed, the guide support rod 10 no longer applies thrust to the adjustable diagonal support plate 9, but when it is retracted, under the action of the reverse thrust of the annular spring piece 12, the adjustable diagonal support plate 9 rotates around the lifting mounting seat 8. The mounting seat 8 is rotated in the opposite direction and reset to allow the sealing ring 27 to be separated from the structure composed of multiple adjustable diagonal support plates 9. A circular mounting buckle 15 is fixedly installed on the top of the adjustable diagonal support plate 9. A rotating rod 16 is rotatably connected inside the circular mounting buckle 15. The circular mounting buckle 15 is used to assist in the installation of the rotating rod 16. The limiting rotating plate 17 is fixedly installed on the rotating rod 16. The limiting rotating plate 17 and the adjustable diagonal support plate 9 form a V-shaped structure to limit the deformed sealing ring 27 to prevent the sealing ring 27 from being separated from the structure composed of multiple adjustable diagonal support plates 9. The limiting rotating plate 17 is fixedly installed on the outer wall of the rotating rod 16. A fixed screw cap 18 is threadedly connected to the rotating rod 16. By twisting the fixed screw cap 18, pressure is applied to the circular mounting buckle 15 to achieve the fixing of the limiting rotating plate 17 after rotation, and the angle of the V-shaped structure formed by the limiting rotating plate 17 and the adjustable diagonal support plate 9 is changed to achieve a better limiting effect or to facilitate the separation of the sealing ring 27.

[0035] The fixed screw cap 18 and the circular mounting buckle 15 are provided with anti-slip grooves on their near sides. After the fixed screw cap 18 and the circular mounting buckle 15 are in contact, friction is generated between the fixed screw cap 18 and the circular mounting buckle 15. The fixation of the limit rotating plate 17 is achieved through the friction between the fixed screw cap 18 and the circular mounting buckle 15.

[0036] A protective pull-out cloth 19 is provided on one side of the limit rotating plate 17 close to the adjustable diagonal support plate 9. The protective pull-out cloth 19 is movably plugged into the adjustable diagonal support plate 9, and is located at the connecting position of the limit rotating plate 17 and the adjustable diagonal support plate 9. The protective pull-out cloth 19 blocks the connecting position of the limit rotating plate 17 and the adjustable diagonal support plate 9 to prevent the position from being exposed, so as to ensure the fixing effect of the sealing ring 27 at the connecting position of the adjustable diagonal support plate 9 and the limit rotating plate 17, and at the same time protect the sealing ring 27 to prevent the sealing ring 27 from being subjected to pressure from a sharp position, which may damage the outer surface of the sealing ring 27 and affect the sealing effect of the sealing ring 27, and the protective pull-out cloth 19 is large in size, and the excess part can be pulled out from the adjustable diagonal support plate 9 to adapt to the rotation of the limit rotating plate 17 around the adjustable diagonal support plate 9.

A second electric push rod 24 is movably mounted on the top of the inclined mounting platform 22 through the connecting plate 23. A sealing ring pressing plate 25 is fixedly mounted on 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 pressing plate 25 to move, and the sealing ring pressing plate 25 is used to press the multiple sealing rings 27 to ensure the movement effect of the sealing rings 27 in the lower barrel 26 to prevent the sealing rings 27 from moving insufficiently due to gravity alone. A lower barrel 26 is fixedly mounted on the bottom of the inclined mounting platform 22, and multiple sealing rings 2 are arranged in the lower barrel 26. 7. A third electric push rod 28 and a fourth electric push rod 29 are fixedly mounted on the discharge barrel 26. A semi-ring limit plate 30 movably inserted in the discharge barrel 26 is fixedly mounted on the piston rod of the fourth electric push rod 29. An inserted fixing piece 31 is fixedly mounted on the piston rod of the third electric push rod 28. The inserted fixing piece 31 and the semi-ring limit plate 30 are respectively located above and below the lowest end sealing ring 27. The inserted fixing piece 31 fixed on the piston rod of the third electric push rod 28 consists of a connecting part and an inserted part. The end of the inserted part is a relatively sharp part to ensure that the inserted fixing piece 31 can be inserted between multiple sealing rings 27. The inserted fixing piece 31 blocks multiple sealing rings 27. The semi-ring limit plate 30 blocks the lowest sealing ring 27. After blocking, the sealing ring 27 is released to let the sealing ring 27 fall.

[0039] A cavity having a shape corresponding to the sealing ring 27 is provided in the discharge barrel 26 to ensure a guiding effect for the multiple sealing rings 27 .

The sliding seat 32 is movably engaged in the inclined mounting platform 22, and the bottom of the sliding seat 32 is rollingly connected to 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. The sliding seat 32 is provided with rollers 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] A dovetail groove corresponding to the shape of the sliding seat 32 is provided on the upper surface of the inclined mounting platform 22 to ensure the moving effect between the sliding seat 32 and the inclined mounting platform 22 and the fixing effect of the inclined mounting platform 22 on the sliding seat 32 .

[0042] The lower material barrel 26 is arranged parallel to the swing arm 6 in the expanded state, and the lower material barrel 26 and the swing arm 6 are parallel to each other, and the structure composed of the adjustable diagonal support plate 9 and the limit rotating plate 17 is located in the direction of the falling of the sealing ring 27 to ensure that the sealing ring 27 is stably mounted outside the structure composed of the adjustable diagonal support plate 9 and the limit rotating plate 17 after falling.

[0043] A through groove is provided at the position of the lower barrel 26 corresponding to the inserted fixing member 31 and the semi-ring limiting plate 30 to ensure the telescopic stroke of the semi-ring limiting plate 30 and the inserted fixing member 31 .

[0044] Working principle:

[0045] Step 1: After the piston rod is transported on the piston rod conveyor belt 2 to the position directly below the assembly rack 5, it stops. The piston rod of the second electric push rod 24 pushes the sealing ring pressing plate 25 to move. The sealing ring pressing plate 25 is located in the discharge barrel 26 and the sealing ring pressing plate 25 contacts the sealing ring 27. The sealing ring 27 is pressed by the sealing ring pressing plate 25 to move the sealing ring 27 in the discharge barrel 26. After the sealing ring 27 contacts the semi-ring limit plate 30, the piston rod of the third electric push rod 28 pushes the inserted fixing part 31 to move. The inserted fixing part 31 is inserted between the lowest sealing ring 27 and the sealing ring 27 above it, so as to realize The sealing ring 27 above the lowest sealing ring 27 is fixed. At this time, the piston rod of the fourth electric push rod 29 is retracted, and the semi-ring limit plate 30 no longer exerts a fixing effect on the sealing ring 27. The sealing ring 27 falls freely due to gravity and falls outside the structure composed of the adjustable diagonal support plate 9 and the limit rotating plate 17. At this time, the piston rod of the fourth electric push rod 29 pushes the semi-ring limit plate 30 to reset, and the piston rod of the third electric push rod 28 also pushes the inserted fixing part 31 to retract. After the inserted fixing part 31 is retracted, the piston rod of the third electric push rod 28 pushes multiple sealing rings 27 to continue to move, and then repeats the operation to realize the control of the movement of the sealing ring 27.

[0046] Step 2: After the sealing ring 27 in the lower barrel 26 is used up, it is necessary to add an additional sealing ring 27 into the lower barrel 26. When adding the sealing ring 27, it is necessary to operate the second electric push rod 24 to retract the sealing ring pressing plate 25 so that the sealing ring pressing plate 25 is no longer in the lower barrel 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 table 22. The feeding port above the lower barrel 26 is exposed, and multiple sealing rings 27 are added into the lower barrel 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 falls on the structure composed of the adjustable diagonal support plate 9 and the limit rotating plate 17, the piston rod of the swing arm 6 pulls the lifting mounting seat 8 to move closer to the swing arm 6, and the guide ball 11 on the end of the guide support rod 10 moves in the guide groove 901. The guide ball 11 moves in the guide groove 901, so that the guide ball 11 applies pressure to the adjustable diagonal support plate 9. After the adjustable diagonal support plate 9 is subjected to pressure, the adjustable diagonal support plate 9 moves around the lifting mounting seat 8 is turned to, during the process of the adjustable diagonal support plate 9 rotating around the lifting mounting seat 8, the adjustable diagonal support plate 9 drives the fixed collar 14 to move, so that the fixed collar 14 applies pressure to the annular spring piece 12, thereby driving the annular spring piece 12 to deform. After the annular spring piece 12 is deformed, a reverse elastic force is generated. The structure composed of multiple adjustable diagonal support plates 9 and the limiting rotating plate 17 unfolds like a petal, and applies pressure to the inner wall of the sealing ring 27, driving the sealing ring 27 to deform, and the sealing ring 27 is located on the adjustable diagonal support plate. 9 and the limit rotating plate 17 connection position, the deformed sealing ring 27 is fixed at the connection position of the limit rotating plate 17 and the adjustable diagonal support plate 9, and contacts with the protective pull-out cloth 19, then the stepping motor 7 is controlled, the swing arm 6 is rotated around the assembly frame 5, so that the assembly frame 5 and the adjustable diagonal support plate 9 are parallel, the sealing ring 27 rotates to reach above the piston rod, the piston rod of the first electric push rod 4 drives the sealing ring 27 to descend, the sealing ring 27 is pre-sleeved on the outside of the piston rod, and the lifting mounting seat 8 is driven by the swing arm 6 piston rod to move away from the swing arm 6 side, the guide ball 11 moves in the opposite direction in the guide slide groove 901, under the action of the reverse elastic force of the annular spring piece 12, the structure composed of multiple adjustable diagonal support plates 9 is reset, and the sealing ring 27 restores the shape before deformation. At the same time, the piston rod of the first electric push rod 4 also pushes the assembly frame 5 to move compensation to ensure that the position of the sealing ring 27 will not change, and the sealing ring 27 after the deformation is restored is sleeved on the piston rod. After the sealing ring 27 is sleeved, the swing arm 6 is reset.

[0048] Step 4: Adjust the limit rotating plate 17 so that the limit rotating plate 17 drives the rotating rod 16 to rotate in the circular mounting buckle 15, and change the angle of the structure composed of the limit rotating plate 17 and the adjustable diagonal support plate 9. After the angle adjustment is completed, turn the fixed screw cap 18 to make the fixed screw cap 18 contact with the circular mounting buckle 15 to achieve the fixation of the limit rotating plate 17 after adjustment, so as to realize the change of the angle between the adjustable diagonal support plate 9 and the limit rotating plate 17, so as to support at different angles.
