Description

Technical Field

[0001] The invention relates to the technical field of sealing ring assembly for oil rings, and in particular to a sealing ring assembly structure for an oil ring production line. Background Art

[0002] Generally, there are oil rings on the piston parts of the piston cylinders of automobiles. The main function of the oil rings is to scrape off the excess oil on the cylinder wall and spread a uniform oil film on the cylinder wall. This can prevent the oil from entering the cylinder and burning, causing problems such as increased fuel and oil consumption and reduced engine power, and can also reduce the wear of the piston, piston ring and cylinder wall, thereby extending the service life of the engine.

[0003] When the existing oil ring is installed on the piston, in order to enhance the sealing performance of the oil ring, a sealing ring is installed on the oil ring, mainly by opening an annular groove in the middle of the outer ring of the oil ring, and then assembling the rubber sealing ring to the annular groove. The main function of the sealing ring is to prevent the lubricating oil from leaking from the gap between the oil ring and the cylinder wall, thereby ensuring the normal operation of the engine or machinery. When assembling the existing sealing ring, it is necessary to first manually expand the sealing ring through an expansion mechanism, then put it on the oil ring, align the position of the annular groove, and then release the sealing ring, so that the sealing ring retracts and snaps into the annular groove to complete the assembly.

[0004] The existing shortcomings of the sealing ring assembly for oil ring production are: although the sealing ring can be assembled to the oil ring by relying on relevant equipment after the existing oil ring production is completed, it needs to be manually operated multiple times. First, the sealing ring is expanded to a size larger than the outer diameter of the oil ring by using an expansion device, for example, the sealing ring is put on a columnar member to expand, and then the oil ring is positioned on one side of the sealing ring by relying on a positioning member, and is aligned with the expanded sealing ring, and then the expanded sealing ring is transported from the columnar member or other expansion device to the oil ring by using a pushing device. During the transportation process, the sealing ring needs to be released in time when the oil ring is aligned with the annular groove on the oil ring, so as to ensure that the sealing ring is stuck in the annular groove to be installed, that is, the existing oil ring sealing ring assembly process needs to be operated multiple times; and after the sealing ring is assembled, it is also necessary to operate separately to remove the assembled oil ring from the positioning member and transport it to the next process for processing, which is not convenient enough and has low operating efficiency.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention relies on a lifting drive mechanism to drive a loading cylinder sleeved with a rubber sealing ring to descend and dock onto an oil ring positioning column. When the loading cylinder relies on a limit column to stop on the oil ring positioning column, the lifting drive mechanism continuously drives the provided lifting rod, and relies on the lifting rod to drive the distributed movable tooth blocks to act on the provided driving gear, so that the annular belt distributed outside the loading cylinder runs, so that it is convenient to drive the sleeved rubber sealing ring by the annular belt to descend and separate from the loading cylinder, so that the rubber sealing ring can be sleeved onto the oil ring component on the oil ring positioning column, and the rubber sealing ring can be automatically fed and assembled at a fixed point only by relying on the lifting movement, and the oil ring component of the assembled rubber sealing ring can be automatically separated during the resetting process of the lifting drive mechanism, and the operation and control are convenient and effective.

[0021] 2. After the oil ring seal at the bottom of the loading cylinder of the present invention is detached and assembled onto the oil ring component, the continuously descending lifting rod can also push the extrusion sleeve arranged at the bottom of the loading cylinder. Since the inner diameter of the extrusion sleeve gradually increases from top to bottom, the outer wall of the oil ring seal can be squeezed by the inclined inner wall during the descending process, thereby facilitating the oil ring seal to be further squeezed into the annular groove on the oil ring component to ensure the assembly effect.

[0022] 3. When the lifting drive mechanism of the present invention drives the loading cylinder to descend, the arranged linkage vertical plate drives the one-way push plate to descend through the arranged U-shaped rotating plate. During this process, the one-way push plate can deflect upward relative to the linkage vertical plate. When the lifting drive mechanism drives the loading cylinder to rise and reset, the arranged linkage vertical plate drives the one-way push plate to rise synchronously. During the rising process, the one-way push plate can squeeze one end of the U-shaped rotating plate to deflect upward, thereby making the other end of the U-shaped rotating plate deflect downward and push the linkage cross bar. The linkage cross bar then pulls down the oil ring positioning column, causing the oil ring positioning column and the annular support plate to descend. Since the oil ring component can be supported by the support ring, the oil ring positioning column and the annular support plate can be separated from the oil ring component, which is convenient for recovering the oil ring component with the sealing ring assembled, and there is no need to separate the oil ring component separately.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-Figure 12 As shown, an oil ring production line sealing ring assembly structure includes a support seat 1 and an oil ring positioning column 5. The four corner positions at the bottom of the support seat 1 can also be fixed with supporting feet to ensure that the bottom surface of the support seat 1 maintains a certain distance from the ground, thereby facilitating the installation of related components at the bottom; the oil ring positioning column 5 is arranged on the support seat 1, and the oil ring positioning column 5 is used to position the oil ring member 4. The oil ring member 4 is an annular structure, which is used to be installed on the piston column to push and scrape the excess oil on the piston cylinder wall or to apply the oil to the piston cylinder wall. In order to avoid a gap between the oil ring member 4 and the cylinder wall to affect the oil scraping effect, a rubber sealing ring 9 is installed on the oil ring member 4. In order to effectively position and install the rubber sealing ring 9, an annular groove matching the rubber sealing ring 9 is opened on the outer wall of the oil ring member 4. During installation, since the rubber sealing ring 9 has a certain elasticity, it can be first opened, then put on the outer wall of the oil ring member 4, and then rely on the rebound force to clamp it into the annular groove on the outer wall of the oil ring member 4 to complete the installation. In order to automatically complete the installation of the rubber sealing ring 9, the assembly structure disclosed in the present invention also includes a lifting ring mechanism and an automatic ring removal mechanism;

[0039] The lifting ring mechanism includes a loading cylinder 8, a lifting drive mechanism and a fixed-point pushing mechanism. The outer wall of the loading cylinder 8 is used to sleeve a plurality of rubber sealing rings 9 at equal intervals, and the loading cylinder 8 is aligned and arranged above the oil ring positioning column 5, and the lifting drive mechanism is used to drive the loading cylinder 8 to move longitudinally; it should be noted that the inner diameter of the loading cylinder 8 is larger than the outer diameter of the oil ring 4, so that the rubber sealing ring 9 can be stretched to a size larger than the oil ring 4, so that it is easy to be sleeved on the oil ring 4; the fixed-point pushing mechanism is arranged on the loading cylinder 8, and when the loading cylinder 8 is lowered and docked on the oil ring positioning column 5, the fixed-point pushing mechanism relies on the longitudinal driving and squeezing action of the lifting drive mechanism to push the rubber sealing ring 9 down to be sleeved on the oil ring 4, so that the rubber sealing ring 9 is automatically installed;

[0040] The automatic ring-removing mechanism is arranged on the support seat 1, and when the lifting drive mechanism drives the loading cylinder 8 to rise, the automatic ring-removing mechanism drives the oil ring positioning column 5 to descend and detach from the oil ring member 4, thereby realizing automatic detachment without manual processing.

[0041] It should be noted that the sealing ring assembly structure disclosed in the present invention can be used in conjunction with an oil ring production line. A conveyor belt can be set on one side, and the produced oil ring parts 4 can be transported one by one to the location of the assembly structure by means of the conveyor belt. At the same time, an intelligent manipulator is also arranged on one side, and the oil ring parts 4 transported on the conveyor belt can be grabbed by the intelligent manipulator, and the oil ring parts 4 are installed on the oil ring positioning column 5. Then, the lifting and lowering drive mechanism is controlled by a control device to facilitate continuous assembly and processing.

[0042] In some specific embodiments, in combination Figure 2 and Figure 3 As shown, the fixed-point pushing mechanism includes a conveyor belt mechanism, a linkage gear 17 and a one-way toggle mechanism. The conveyor belt mechanism is provided with multiple groups and is equidistantly distributed on the outer wall of the loading cylinder 8 in the circumferential direction. The rotating end of each conveyor belt mechanism near the top of the loading cylinder 8 is coaxially fixedly connected with the linkage gear 17. A cover plate 20 is aligned above the loading cylinder 8, and the cover plate 20 is connected to the lifting end of the lifting drive mechanism. The one-way toggle mechanism is provided with multiple groups and is equidistantly distributed at the bottom of the cover plate 20 in the circumferential direction. The one-way toggle mechanism is correspondingly matched and connected with the linkage gear 17. A linkage ring 24 is commonly connected between all the one-way toggle mechanisms. A limit column 22 aligned with the oil ring positioning column 5 is fixedly connected to the inner side of the loading cylinder 8 near the bottom position, and an elastic telescopic connecting piece is provided between the linkage ring 24 and the limit column 22.

[0043] Among them, the elastic telescopic connecting part includes an elastic telescopic rod 23 and a connecting cross plate. The connecting cross plate is fixedly connected to the inner side of the linkage ring 24. The elastic telescopic rod 23 is connected between the connecting cross plate and the limit column 22. The elastic telescopic rod 23 includes a telescopic rod body and a compressible spring sleeved on the telescopic rod body.

[0044] When multiple rubber sealing rings 9 are equidistantly and longitudinally sleeved on the outer wall of the loading cylinder 8, the inner ring of each rubber sealing ring 9 contacts the conveying surface of the conveyor belt mechanism distributed on the outer wall of the loading cylinder 8. When the lifting drive mechanism drives the cover plate 20 to descend, the loading cylinder 8 synchronously descends and approaches the oil ring positioning column 5. When the limit column 22 on the inner side of the loading cylinder 8 descends and hits the top of the oil ring positioning column 5, the loading cylinder 8 cannot continue to descend. At this time, the bottom edge of the loading cylinder 8 is just aligned with the upper edge of the annular groove on the outer wall of the oil ring 4. At this time, the lifting drive mechanism continues to drive the cover plate 20 to descend, and the cover plate 20 drives the distributed one-way toggle mechanism to move relatively. As the loading cylinder 8 descends, the elastic telescopic rod 23 is compressed, and all the one-way toggle mechanisms descend synchronously, thereby toggling all the linkage gears 17 to rotate, and each linkage gear 17 drives the corresponding conveyor belt mechanism to operate, thereby facilitating the synchronous descent of all the longitudinally distributed rubber sealing rings 9, and the running distance is just the thickness of a rubber sealing ring 9, so that the rubber sealing ring 9 on the lowest side descends and detaches from the loading cylinder 8, and just fits onto the oil ring 4, and because the bottom edge of the loading cylinder 8 is aligned with the upper edge of the annular groove on the oil ring 4, it is convenient for the detached rubber sealing ring 9 to fit into the position of the annular groove.

[0045] In some specific embodiments, such as Figure 3 As shown, each set of conveyor belt mechanisms includes an endless belt 15, a transmission wheel 21 and a mounting groove 14. The mounting groove 14 is opened on the outer wall of the loading cylinder 8 and is vertically distributed. Two transmission wheels 21 are provided and are rotatably connected to the upper and lower sides of the mounting groove 14 respectively. The endless belt 15 is cooperatively connected between the two transmission wheels 21. The endless belt 15 is in the shape of a crawler and has anti-slip protrusions on the surface. The transmission wheel 21 on the upper side of the mounting groove 14 is coaxially fixedly connected with the corresponding linkage gear 17.

[0046] When the rubber sealing ring 9 is sleeved onto the outer wall of the loading tube 8 , the inner ring side wall of the rubber sealing ring 9 contacts the outer surface of the annular belt 15 .

[0047] In some specific embodiments, in combination Figure 4 and Figure 5As shown, each set of one-way toggle mechanisms includes a lifting rod 18, a movable tooth block 19 and a driving gear 27. A plurality of notches 16 are equidistantly distributed around the top edge of the loading cylinder 8. The linkage gears 17 are correspondingly located in the notches 16. The driving gears 27 of each set of one-way toggle mechanisms are correspondingly connected to the notches 16 by rotating the shafts, and the driving gears 27 are meshed with the corresponding linkage gears 17. The lifting rods 18 are vertically fixedly connected to the bottom of the cover plate 20, and each lifting rod 18 is fixedly connected to the linkage ring 24. The side of the lifting rod 18 close to the driving gear 27 is longitudinally and equidistantly connected to the bottom of the cover plate 20. There are multiple movable tooth blocks 19 distributed at a certain distance, and one side end face of each movable tooth block 19 is in contact with the outer wall of the lifting rod 18, and the bottom edge of one side end face of the movable tooth block 19 that is in contact with the lifting rod 18 is movably connected with the lifting rod 18 through a rebound hinge, that is, the movable tooth block 19 can only be deflected downward from a horizontal position, and cannot be deflected upward from a horizontal position. The movable tooth blocks 19 distributed on the lifting rod 18 can engage with the corresponding driving gear 27. It should be noted that before the elastic telescopic rod 23 is compressed, the distributed movable tooth blocks 19 are all higher than the position of the corresponding driving gear 27.

[0048] When the cover plate 20 descends relative to the loading cylinder 8, each of the distributed lifting rods 18 descends synchronously, and the lifting rods 18 drive the distributed movable tooth blocks 19 to descend and pass through the corresponding driving gear 27. During this process, the movable tooth blocks 19 cannot deflect upward relative to the lifting rods 18. Therefore, when the movable tooth blocks 19 pass through the driving gear 27, they drive the driving gear 27 to rotate, and the driving gear 27 drives the linkage gear 17 to rotate, and the linkage gear 17 drives the transmission wheel 21 to rotate, and the transmission wheel 21 drives the annular belt 15 to run, so as to facilitate the displacement of the rubber sealing ring 9. When the lifting rods 18 drive the distributed movable tooth blocks 19 to completely pass through the driving gear 27 and then rise again, since the movable tooth blocks 19 can deflect downward relative to the lifting rods 18 at this time, they can be squeezed through the driving gear 27 and will not drive the driving gear 27 to rotate.

[0049] It should be noted that, in order to prevent the driving gear 27 from accidentally rotating, a non-slip rubber sleeve may be sleeved on the rotating shaft connected to the driving gear 27 , and the non-slip rubber sleeve is fixedly connected to the inner wall of the notch 16 .

[0050] In other specific embodiments, in combination Figure 3 and Fig.10 As shown, an extrusion sleeve 26 is provided in a sliding manner at the bottom of the loading cylinder 8, and the inner diameter of the extrusion sleeve 26 gradually increases from top to bottom, the inner diameter of the top of the extrusion sleeve 26 is larger than the outer diameter of the oil ring 4, and the top edge of the extrusion sleeve 26 is aligned with the bottom of the lifting rod 18, and limiting grooves 25 are provided on the inner walls on both sides of the bottom of the loading cylinder 8, and a protrusion is fixedly provided on the top edge of the extrusion sleeve 26, and is slidably connected to the limiting groove 25 through the protrusion, and a compressible support spring is connected between the extrusion sleeve 26 and the limiting groove 25.

[0051] After the cover plate 20 drives the distributed lifting rods 18 to descend relative to the loading cylinder 8, and the lifting rods 18 drive the distributed movable gear blocks 19 to descend and pass through the driving gear 27, the rubber sealing ring 9 at the lowest side of the loading cylinder 8 is separated from the loading cylinder 8 and is sleeved onto the oil ring 4, and sleeved onto the annular groove of the outer wall of the oil ring 4. At this time, the bottom of the lifting rod 18 just drops and contacts the top edge of the extrusion sleeve 26, and the lifting drive mechanism continues to drive the cover plate 20 to descend, and the lifting rod 18 keeps descending, thereby pushing the extrusion sleeve 26 downward, and the extrusion sleeve 26 slides down relative to the loading cylinder 8, thereby squeezing the outer ring side wall of the rubber sealing ring 9 sleeved on the annular groove of the oil ring 4, and relying on the inclined wall to produce an extrusion effect on the rubber sealing ring 9, so that the rubber sealing ring 9 is subjected to the gathering force and further effectively stuck into the annular groove of the oil ring 4, ensuring the effective assembly of the rubber sealing ring 9.

[0052] It should be noted here that, because the rubber sealing ring 9 needs to be firmly assembled in the position of the annular groove, the thickness of the rubber sealing ring 9 naturally needs to be slightly larger than the longitudinal width of the annular groove. However, this may result in the rubber sealing ring 9 being unable to fully enter the annular groove during assembly. Therefore, the extrusion sleeve 26 is required to finally squeeze the rubber sealing ring 9 to make it close in place.

[0053] In some specific embodiments, in combination Figure 7 and Figure 8 As shown, the automatic ring-removing mechanism includes an annular support plate 6 and a linkage sliding mechanism. The annular support plate 6 is fixedly connected to the oil ring positioning column 5, and an annular enclosure is provided on the edge of the annular support plate 6. When the oil ring 4 is sleeved on the oil ring positioning column 5, the bottom of the oil ring 4 is supported by the annular support plate 6, and the annular enclosure is shielded on the outside of the oil ring 4. The upper edge of the annular enclosure is aligned with the lower edge of the annular groove on the oil ring 4. Due to the existence of the annular enclosure, the rubber sealing ring 9 can be prevented from being sleeved to the bottom position of the oil ring 4 and deviating from the position of the annular groove; the oil ring positioning column 5 slides through the support seat 1, and a connecting spring 32 is connected between the bottom of the oil ring positioning column 5 and the bottom of the support seat 1, and the connecting spring 32 can be stretched; the oil ring positioning column 5 and the lifting end of the lifting drive mechanism are connected through a linkage sliding mechanism; an annular fitting groove 30 is provided on the annular supporting plate 6, and a supporting ring 31 is embedded in the annular fitting groove 30, and a plurality of supporting rods 29 are distributed circumferentially at the bottom of the supporting ring 31, and each supporting rod 29 penetrates the annular supporting plate 6 and is fixedly connected to the support seat 1, and the annular supporting plate 6 can slide relative to the supporting rod 29.

[0054] Among them, the linked sliding mechanism includes a U-shaped swivel plate 12, a linkage cross bar 28 and a one-way push plate 11; both sides of the bottom of the support seat 1 are fixedly connected with shaft frames 13, the U-shaped swivel plate 12 is rotatably connected between the two shaft frames 13 through a rotating shaft, two linkage cross bars 28 are provided, and are symmetrically fixedly connected to both sides of the bottom of the oil ring positioning column 5, and one end of the U-shaped swivel plate 12 is matched to rest on the linkage cross bar 28, and one side of the driving end of the lifting drive mechanism is fixedly connected with a linkage vertical plate 10, the one-way push plate 11 is horizontally arranged at the bottom of the linkage vertical plate 10, and the one-way push plate 11 is aligned with the other end of the U-shaped swivel plate 12, one end of the one-way push plate 11 is attached to the vertical end face of the linkage vertical plate 10, and the upper side edge of the end of the one-way push plate 11 attached to the linkage vertical plate 10 is movably connected to the linkage vertical plate 10 through a rebound hinge, so that the one-way push plate 11 can only be deflected upward from a horizontal position, and cannot be deflected downward from a horizontal position.

[0055] When the lifting drive mechanism drives the loading cylinder 8 to descend, the linkage vertical plate 10 descends synchronously and brings the one-way push plate 11 with it. When the loading cylinder 8 descends and connects to the oil ring positioning column 5 to assemble the rubber sealing ring 9, the one-way push plate 11 has squeezed through the end of the U-shaped rotating plate 12. During this process, the one-way push plate 11 deflects upward relative to the linkage vertical plate 10. When the lifting drive mechanism drives the loading cylinder 8 to rise, the one-way push plate 11 below the end of the U-shaped rotating plate 12 rises synchronously. Then the one-way push plate 11 squeezes and pushes one end of the U-shaped rotating plate 12 upward. The U-shaped rotating plate 12 deflects, and the other end deflects downward, thereby pushing the distributed linkage cross bar 28 downward. The linkage cross bar 28 drives the oil ring positioning column 5 to slide down relative to the support seat 1. The oil ring positioning column 5 drives the annular support plate 6 to descend and disengage from the oil ring component 4 assembled with the rubber sealing ring 9. At this time, the oil ring component 4 is kept in its original position by the support ring 31, which is convenient for direct removal.

[0056] In some specific embodiments, such as Figure 1 As shown, in order to facilitate the automatic transportation of the oil ring component 4 that has detached from the oil ring positioning column 5 to one side, an electric push rod 7 is fixedly connected to one side of the support seat 1, and the telescopic end of the electric push rod 7 is aligned with the position of the oil ring component 4, and the other side is fixedly connected to an inclined guide plate 3 for guiding the oil ring component 4 to slide, and a recovery box or a conveyor belt can be placed on the end of the inclined guide plate 3, and a pressure sensing switch aligned with the annular support plate 6 is installed on the surface of the support seat 1, and the pressure sensing switch is electrically connected to the electric push rod 7.

[0057] When the oil ring positioning column 5 drives the annular support plate 6 to descend and detach from the oil ring component 4, the annular support plate 6 finally hits the surface of the support seat 1, exerting an extrusion effect on the pressure sensing switch. The pressure sensing switch then extends the electric push rod 7, and the electric push rod 7 pushes the oil ring component 4 on the support ring 31, pushing it onto the inclined guide plate 3, and the oil ring component 4 falls onto the inclined guide plate 3, and then slides onto the recovery box or the conveyor belt.

[0058] In some specific embodiments, the lifting drive mechanism includes an electric telescopic rod 2, which is fixedly connected to one side of the support seat 1, with the telescopic end facing upward, and the telescopic end of the electric telescopic rod 2 is fixedly connected to a horizontal frame, and the cover plate 20 and the linkage vertical plate 10 are both fixedly connected to the horizontal frame.

[0059] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0060] First, the oil ring 4 transported on the conveyor belt is grabbed by the intelligent manipulator, and the oil ring 4 is installed on the oil ring positioning column 5. At this time, the bottom of the oil ring 4 is supported by the annular support plate 6, and the annular enclosure is blocked on the outside of the oil ring 4. The upper edge of the annular enclosure is aligned with the lower edge of the annular groove on the oil ring 4. Due to the existence of the annular enclosure, it can be avoided that when the rubber sealing ring 9 is installed, the rubber sealing ring 9 is prevented from being put on the bottom position of the oil ring 4 and deviating from the position of the annular groove.

[0061] After the oil ring 4 is positioned, the electric telescopic rod 2 starts to shrink, driving the cover plate 20 to descend, and the loading cylinder 8 is synchronously lowered to approach the oil ring positioning column 5. When the limit column 22 inside the loading cylinder 8 descends and hits the top of the oil ring positioning column 5, the loading cylinder 8 cannot continue to descend, and at this time, the bottom edge of the loading cylinder 8 is just aligned with the upper edge of the annular groove on the outer wall of the oil ring 4; at this time, the lifting drive mechanism continues to drive the cover plate 20 to descend, and the cover plate 20 drives the distributed lifting rods 18 to descend relative to the loading cylinder 8. During this process, the elastic telescopic rod 23 is compressed, and the lifting rod 18 drives the distributed movable tooth block 19 to descend through the position of the corresponding driving gear 27. During this process, the movable tooth block 19 cannot deflect upward relative to the lifting rod 18, so the movable tooth block When 19 passes through the driving gear 27, it drives the driving gear 27 to rotate, and the driving gear 27 drives the linkage gear 17 to rotate, and the linkage gear 17 drives the transmission wheel 21 to rotate, and the transmission wheel 21 drives the annular belt 15 to run, so as to facilitate the pushing of all the longitudinally distributed rubber sealing rings 9 to descend relative to the loading cylinder 8, and the running distance is just the thickness of a rubber sealing ring 9, so that the rubber sealing ring 9 on the lowest side descends and detaches from the loading cylinder 8, and just fits on the oil ring 4, and because the bottom edge of the loading cylinder 8 is aligned with the upper edge of the annular groove on the oil ring 4, and the annular enclosure on the annular support plate 6 is aligned with the lower side edge of the annular groove of the oil ring 4, it is convenient for the rubber sealing ring 9 detached from the loading cylinder 8 to be fitted to the position of the annular groove on the oil ring 4.

[0062] And after the lifting rod 18 drives the distributed movable tooth block 19 to completely pass the position of the driving gear 27, the bottom of the lifting rod 18 just drops and contacts the top edge of the extrusion sleeve 26, and the electric telescopic rod 2 continues to shrink and drive the cover plate 20 to drop, and the lifting rod 18 keeps dropping, thereby pushing the extrusion sleeve 26 downward, and the extrusion sleeve 26 slides down relative to the loading cylinder 8, and compresses the support spring, thereby squeezing the outer ring side wall of the rubber sealing ring 9 at the annular groove of the oil ring part 4, and relying on the inclined wall to squeeze the rubber sealing ring 9, the rubber sealing ring 9 is subjected to the gathering force and further effectively stuck in the annular groove of the oil ring part 4, ensuring the effective assembly of the rubber sealing ring 9.

[0063] When the electric telescopic rod 2 drives the loading cylinder 8 to descend, the linkage vertical plate 10 descends synchronously, and brings the one-way push plate 11 down with it. When the loading cylinder 8 descends and docks with the oil ring positioning column 5 to assemble the rubber seal 9, the one-way push plate 11 has squeezed through the end of the U-shaped rotating plate 12. During this process, the one-way push plate 11 deflects upward relative to the linkage vertical plate 10. When the electric telescopic rod 2 drives the loading cylinder 8 to rise, the one-way push plate 11 below the end of the U-shaped rotating plate 12 rises synchronously, and then the one-way push plate 11 squeezes and pushes one end of the U-shaped rotating plate 12 upward, and the U-shaped rotating plate 12 deflects, and the other end deflects downward, thereby pushing the distributed linkage cross bar 28 downward, and the linkage cross bar 28 drives the oil ring positioning column 5 to slide downward relative to the support seat 1, and the oil ring positioning column 5 drives the annular support plate 6 to descend and separate from the oil ring component 4 assembled with the rubber seal 9, and at this time the oil ring component 4 is kept in its original position by the support ring 31;

[0064] When the annular support plate 6 contacts the surface of the support seat 1, it exerts an extrusion effect on the pressure sensing switch, which causes the electric push rod 7 to extend. The electric push rod 7 pushes the oil ring 4 on the support ring 31 and pushes it onto the inclined guide plate 3. The oil ring 4 falls onto the inclined guide plate 3 and then slides onto the recovery box or the conveyor belt.

[0065] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
