Description

Technical Field

[0001] The present invention relates to the technical field of deep well pump assembly equipment, and in particular to an O-ring feeding device. Background Art

[0002] A deep well pump is a type of pumping equipment specifically used for extracting and transporting water deep into groundwater. It usually cleverly integrates the motor and the pump body into one.

[0003] Existing deep well pumps have a very wide range of applications and are often used in many fields such as farmland irrigation and drainage, water circulation in industrial and mining enterprises, urban water supply and drainage systems, and sewage treatment. Before starting the deep well pump, a key step is to ensure that the suction pipe and the inside of the pump body are completely filled with liquid. The end also needs to be tightly sealed by the end cover. To further enhance the sealing effect, an O-ring is often installed on the end cover for sealing.

[0004] The current installation method of the O-ring of the oil tank cover is manual installation by the operator, which takes a lot of time. Manual installation is limited by the structure of the O-ring's material and size, making installation difficult. As a result, the O-ring cannot be fully stretched and installed due to insufficient force, affecting the installation quality. The installation is difficult and needs to be improved. Summary of the Invention

[0005] In order to improve the problem that manual installation of O-rings with different stretching difficulties easily leads to greater difficulty in installation, this technical solution provides an O-ring feeding device.

[0006] The purpose of this technical solution is achieved in this way:

[0007] An O-ring feeding device is used to put the O-ring on the outside of the adapted oil tank cover, comprising a frame and an O-ring feeding device, which is arranged on the frame and is used to store and transport the O-ring;

[0008] An O-ring transfer device is provided on the frame, wherein a clamp mechanism for clamping the O-ring is provided at the lower portion of the O-ring transfer device, and is used to clamp the O-ring from the O-ring feeding device to the support ring positioning device;

[0009] A support ring positioning device is provided beside the support ring positioning device and is used to stretch and position the O-ring clamped by the clamp mechanism;

[0010] The expansion ring installation device is arranged next to the support ring positioning device. The expansion ring installation device includes an expansion ring assembly, a mounting assembly and a drive assembly. The drive assembly drives the expansion ring assembly to expand the O-ring on the support ring positioning device, so that the mounting assembly installs the O-ring on the oil tank cover.

[0011] Through the above technical solution, when the O-ring loading device is in normal use, O-ring materials are prepared on the O-ring feeding device, which drives the O-rings to be transported one by one to the preset position on the frame. The O-ring transfer device drives the clamping mechanism at its lower part to accurately clamp an O-ring located on the frame and transfer it to the support ring positioning device. The support ring positioning device then stretches and expands the O-ring and then releases the O-ring. Since the O-ring itself has a certain elastic force, it naturally rebounds to a more central position, thereby determining the positioning of the O-ring before installation and improving the subsequent support ring accuracy.

[0012] The expansion ring installation device drives the expansion ring assembly provided at the bottom thereof to approach the O-ring on the support ring positioning device through the driving assembly, thereby expanding the O-ring. The O-ring has a certain elastic force. The driving assembly moves the expansion ring installation device close to the oil tank cover, and the installation assembly sets the O-ring to the outside of the oil pipe cover to complete the installation of the O-ring, improve the positioning effect of the O-ring during installation, automatically install the O-ring, reduce the installation difficulty, and thus improve the installation quality of the O-ring.

[0013] Preferably, the support ring positioning device includes a mounting frame 1 and a support ring assembly provided on the mounting frame 1;

[0014] The upper end of the mounting frame 1 is provided with a material tray portion, the material tray portion is provided with a plurality of movable grooves along the circumference, and the support ring assembly is provided at the lower portion of the material tray portion;

[0015] The support ring assembly includes a support ring driving member, a rotating shaft, and a support ring member that slides below the movable groove. The rotating shaft is provided with threaded segments with opposite spiral directions at both ends. The support ring member is provided with two, and the support ring members are respectively threadedly connected to the corresponding threaded segments. The support ring member has a support ring column, and the upper ends of the two support ring columns pass through the corresponding movable grooves.

[0016] The support ring driving member drives the two support ring members to move closer to or away from each other through the rotating shaft, thereby achieving the positioning of the O-ring on the material tray part.

[0017] Through the above technical solution, after an O-ring is placed flat on the upper end surface of the tray part of the mounting frame, both support ring members pass upward through the movable groove of the tray part to be located on the inner side of the O-ring ring, and the support ring driving member drives the rotating shaft to rotate. Based on the two support ring members respectively cooperating with the threaded sections with opposite spiral directions at both ends of the rotating shaft, the two support ring members slide synchronously in opposite directions, and the two support ring members located on the opposite sides form balanced expansion force points at both ends of the O-ring, which expands the O-ring to make its shape more stable and uniform, and the center of the O-ring is closer to the midpoint between the two support ring members, ensuring the smoothness and efficiency of the O-ring expansion process.

[0018] Preferably, the expansion ring installation device further comprises a second mounting frame, a sliding platform is slidably provided on the second mounting frame, a mounting seat is slidably provided on the sliding platform, and the sliding direction of the sliding platform is perpendicular to the sliding direction of the mounting seat.

[0019] The mounting seat is provided with the expansion ring assembly and the mounting assembly, and the driving assembly includes a sliding driving component 1 and a sliding driving component 2. The sliding driving component 1 drives the sliding platform to move between the first position and the second position, and the sliding driving component 2 drives the mounting seat to rise and fall.

[0020] Through the above technical solution, the sliding drive component drives the sliding platform to slide, so as to drive the position adjustment of the expansion ring assembly and the installation assembly in the horizontal direction, thereby realizing repeated switching and movement of the position between the support ring positioning device and the oil tank cover. When the expansion ring assembly is located at the support ring positioning device, the sliding drive component drives it downward to approach the O-ring to obtain the O-ring. When the expansion ring assembly is located at the oil tank cover, the sliding drive component drives it downward to approach the oil tank cover, and the installation assembly installs the O-ring on the oil tank cover, which has better operational flexibility and improves installation efficiency.

[0021] Preferably, the expansion ring assembly includes an expansion ring base, which is rotatably arranged at the lower part of the mounting seat, and the mounting seat is provided with a rotation driving member for driving the expansion ring base to rotate;

[0022] A movable block is slidably arranged at the lower part of the expansion ring base. The movable blocks include a plurality of movable blocks, the positions of which correspond to the distribution of the movable grooves one by one, and the lower end of the movable block protrudes with a movable column;

[0023] The expansion ring drive member drives all the movable blocks to slide synchronously through the transmission structure, so that the movable column expands the O-ring outward.

[0024] Through the above technical solution, the rotating driving member drives the expansion ring base to rotate and adjust around the axial direction, ensuring that the position of the movable column in each movable block can pass through the position of the movable groove one by one, and the expansion ring driving member drives all the movable blocks to slide outward. Based on the sliding direction of each movable block, the O-ring is evenly stretched from the inside by the movable column, the shape becomes more stable, and the tension is more uniform. The O-ring fastening ring is sleeved on the outside of all movable columns, thereby realizing the O-ring acquisition and improving the installation accuracy and efficiency of the O-ring.

[0025] Preferably, the mounting assembly includes a stripping drive member and a stripping plate provided at the output end of the stripping drive member, the stripping plate is slidably connected to the expansion ring base, and the expansion ring base is provided with a guide column penetrating the stripping plate to guide the sliding;

[0026] The stripping plate is provided with a plurality of stripping members, and the stripping members are movably arranged on the movable block in a one-to-one correspondence. An elastic member is sleeved on the stripping member, and the elastic force of the elastic member makes the stripping member have a tendency to press against the stripping plate;

[0027] The stripping drive member drives the stripping plate to slide, so as to push all the stripping members to move synchronously, so that the lower end of the stripping member separates the O-ring from the movable column.

[0028] Through the above technical solution, when the expansion ring base approaches the oil tank cover to a specified height, the O-ring is surrounded in the fitting position, and the stripping drive drives the stripping plate to slide. The stripping plate overcomes the elastic force of the elastic part and compresses the elastic part. Based on the sliding fitting connection between the stripping part and the movable block, the stripping part is pushed downward relative to the movable block until it is misaligned with the movable column. At this time, the lower end of the stripping part can push the O-ring against the movable column to separate the O-ring from the movable column, thereby realizing the ring sleeve on the outside of the oil tank cover.

[0029] Preferably, the transmission structure includes a gear 1, a gear 2 and a spiral chassis rotatably arranged on the expansion ring base, the gear 1 is arranged at the output end of the expansion ring driving member, the gear 2 is meshed with the gear 1, and the gear 2 is coaxially arranged with the spiral chassis;

[0030] The spiral chassis is provided with a plurality of guide grooves, the positions of which correspond one to one with the movable block. The upper end of the movable block is provided with a guide portion, which is located in the guide groove. The extension direction of the guide groove guides the movement of the guide portion to realize the sliding of the movable block.

[0031] Through the above technical solution, the expansion ring driving member drives gear 1 to rotate from the output end, and based on the engagement of gear 1 and gear 2, gear 2 is driven to rotate, and the rotation of gear 2 drives the spiral chassis to rotate. Due to the different rotation directions of the spiral chassis, the guide groove on the spiral chassis guides the guide part in the opposite direction, thereby realizing the synchronous sliding gathering or expansion of the movable block and improving the accuracy of the operation.

[0032] Preferably, the frame is provided with a material preparation bin and an edge detection device, the material preparation bin is connected to the discharge end of the O-ring feeding device, the edge detection device is mounted above the material preparation bin, and the detection end of the edge detection device faces the material preparation bin to identify the edge contour of the O-ring;

[0033] The O-ring transfer device includes a transfer drive, a first crank arm provided at the output end of the transfer drive, and a second crank arm rotatably provided at the other end of the first crank arm;

[0034] The clamp mechanism is provided at the end of the second crank arm, and the second crank arm drives the clamp mechanism to rise and fall through a screw structure.

[0035] Through the above technical solution, the material preparation bin is placed on the frame and has a box-shaped structure. The material preparation bin can accommodate the O-rings delivered by the O-ring loading device, limit the random scattering of the O-rings, and provide convenience for subsequent detection and clamping operations; the edge detection device has the function of contour detection, and its detection end is facing the O-ring on the frame. Based on the O-ring being a linear ring, it can identify and capture the overall contour information of the O-ring, so as to facilitate the clamping mechanism to clamp the edge of the O-ring, thereby improving the accuracy and efficiency of O-ring clamping and loading.

[0036] The transfer drive drives the first crank arm to rotate through the output end. Since the other end of the first crank arm is hinged to the second crank arm, the second crank arm can also rotate and adjust relatively to form a two-section crank arm swinging structure, which has a wider working coverage range and is more flexible in use. The second crank arm can drive the clamp mechanism to move above the preparation bin, or move to above the tray part to respectively perform the operations of obtaining the O-ring and placing it. Among them, when the clamp mechanism reaches the predetermined position, the clamping drive drives the clamp mechanism at its lower end to approach the O-ring, and the clamp mechanism clamps the edge of the O-ring. At this time, the transfer drive drives the first crank arm and the second crank arm to operate, and transfer the O-ring to the tray part to complete the transfer and installation tasks of the O-ring. During the whole process, the transfer drive, the first crank arm, the second crank arm and the clamp mechanism work together to achieve precise clamping and transfer of the O-ring, further ensuring the accuracy and efficiency of the installation.

[0037] Preferably, the O-ring feeding device includes a feeding mechanism and a shifting mechanism, and the shifting mechanism drives the feeding mechanism to move;

[0038] The shift mechanism includes a first sliding cylinder, a slide table sliding on the frame, a second sliding cylinder, and a slide frame sliding on the slide table. The first sliding cylinder and the second sliding cylinder respectively drive the slide table and the slide frame to move in a one-to-one correspondence. The sliding direction of the slide table is perpendicular to the sliding direction of the slide frame.

[0039] The feeding mechanism includes an O-ring material rack arranged on the slide, a storage rod arranged horizontally on the O-ring material rack, and a feeding structure. A plurality of O-rings are hung on the storage rod, and the feeding structure is used to push the O-rings on the storage rod to feed.

[0040] The O-ring feeding device is installed on the frame, and several O-rings are neatly hung on the storage rod in the feeding mechanism for storage. Sliding cylinder 1 drives the slide to slide, driving the slide to move in the horizontal direction, while sliding cylinder 2 drives the slide to slide, driving the feeding mechanism to move in the horizontal direction perpendicular to the sliding direction of the slide, thereby realizing the position adjustment of the feeding mechanism between the two axes, improving the positioning accuracy, and improving the flexibility of the feeding mechanism in the two-dimensional plane; when the front end of the storage rod is located above the preparation bin, the feeding structure pushes the O-rings arranged on the storage rod to move forward, ensuring that the O-rings move forward step by step in a predetermined order and fall into the preparation bin below (the preparation bin is located on the frame, adjacent to the frame), thereby realizing continuous replenishment and feeding of O-rings, automated operation, and improved production efficiency.

[0041] Preferably, the feeding structure includes a feeding drive and a feeding plate slidably connected to the O-ring material rack, and the feeding drive drives the feeding plate to slide along the length direction of the O-ring material rack, so as to push the O-ring to detach from the front end of the storage rod.

[0042] Through the above technical solution, the feeding drive member drives the feeding plate to slide along the length direction of the O-ring material rack. This action causes the feeding plate to push the O-rings arranged on the storage rod forward, thereby realizing the output of the O-rings.

[0043] Preferably, the O-ring material rack is further provided with a material limiting structure, which includes a material limiting driving member and a material limiting plate sliding on the O-ring material rack, and the material limiting plate is arranged in alignment with the end of the material storage rod through the opening of the O-ring material rack;

[0044] The material limiting driving member drives the material limiting plate to move, so as to change the clearance distance between the material limiting plate and the material storage rod.

[0045] Through the above technical solution, the material limiting driving member in the material limiting structure drives the material limiting plate to slide on the O-ring material rack, adjusts the gap between the material limiting plate and the end of the storage rod, and realizes effective control of the O-ring supply through precise regulation. When there is a gap, the O-ring can pass through to ensure that an appropriate number of O-rings are pushed to the working area each time. When there is no gap, the O-ring is restricted from leaving the storage rod, thereby realizing precise and orderly management of O-ring replenishment and material limiting.

[0046] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0047] 1. This technical solution is equipped with an O-ring feeding device, an O-ring transfer device, a support ring positioning device and an expansion ring installation device. The O-ring feeding device feeds the O-ring to the frame, the O-ring transfer device transfers the O-ring to the support ring positioning device, the support ring positioning device pulls and expands the O-ring and then positions it, and the expansion ring installation device expands the O-ring so that it moves and fits on the outside of the oil tank cover. This automates the installation of the O-ring, reduces the installation difficulty, and improves the installation quality of the O-ring.

[0048] 2. This technical solution is to set up an edge detection device on the frame, and use the detector installed on the mounting frame to identify the outline of the O-ring and determine its edge position, so as to ensure that the clamping mechanism in the O-ring transfer device can clamp the edge and move it, thereby improving the accuracy and efficiency of O-ring clamping and loading.

[0061] Example:

[0062] See also Figure 1 , an O-ring feeding device, used to put the O-ring on the outside of the compatible oil tank cover, including a frame 1. The frame 1 shown in this embodiment includes two frame parts, which are placed adjacent to each other, and also includes an O-ring feeding device 2, an O-ring transfer device 3, a support ring positioning device 4, an expansion ring installation device 5 and a boundary detection device 11, wherein the O-ring feeding device 2 is installed on the frame 1 part located on the rear side, the O-ring transfer device 3 and the boundary detection device 11 are installed on the frame 1 part located on the front side, and the support ring positioning device 4 and the expansion ring installation device 5 are installed on the side of the front frame 1.

[0063] See also Figure 2 and Figure 3The O-ring feeding device 2 includes a feeding mechanism 21 and a shifting mechanism 22. The shifting mechanism 22 drives the feeding mechanism 21 to move its position. In this embodiment, two groups of feeding mechanisms 21 are provided; the shifting mechanism 22 includes a sliding cylinder 1 221, a slide 222, a sliding cylinder 223 and a slide 224. The slide 222 is slidably installed on the upper end surface of the frame 1 through a slide rail structure, and its sliding direction is along the horizontal direction. The sliding cylinder 1 221 is fixed on the frame 1 and the output shaft drives the slide 222 to slide.

[0064] There are two slides 224 distributed at intervals along the sliding direction of the slide 222. Both slides 224 are slidably installed on the slide 222 through a slide rail structure, and their sliding directions are perpendicular to the sliding direction of the slide 222 along the horizontal direction; two sliding cylinders 223 are installed on the slide 222 corresponding to the two slides 224, driving the corresponding slides 224 to slide, driving the loading mechanism 21 on the slide 224 to slide along the second direction, and cooperating with the sliding cylinder 1 221 to drive the loading mechanism 21 to slide along the first direction, thereby realizing the position change of the loading mechanism 21 on the horizontal plane along the XY axis.

[0065] The feeding mechanism 21 includes an O-ring material rack 211, a storage rod 212 and a feeding structure 213. The O-ring material rack 211 is arranged at the upper end of the corresponding slide 224, and has two rods extending forward and horizontally. The storage rod 212 is arranged horizontally parallel to the rod; the O-rings are stored in the storage rod 212.

Alternatively, the thread structure of the feeding plate 2132 can be matched with the distribution of the O-rings to make the thread progressively advance the O-rings.

[0066] Each O-ring material rack 211 is provided with a material limiting structure 15, which is located on the front end side of the O-ring material rack 211 corresponding to the material storage rod 212, and includes a material limiting driving member 151 and a material limiting plate 152. The O-ring material rack 211 leaves a clearance opening for the material limiting plate 152, and the lower part of the material limiting plate 152 passes through the clearance opening. The material limiting plate 152 is set on the output shaft of the material limiting driving member 151 and slides relative to the O-ring material rack 211, and its sliding direction is parallel to the sliding direction of the feeding plate 2132. The material limiting driving member 151 drives the material limiting plate 152 to slide. When the material limiting plate 152 abuts against the end of the material storage rod 212, it limits the O-ring from leaving the material storage rod 212. When the material limiting plate 152 leaves the storage rod 212, a gap is left between the material limiting plate 152 and the end of the storage rod 212 for the O-ring to pass through.

[0067] See also Figure 4 , a material preparation bin 17 is provided on the frame 1, which is in the shape of a box with an open top and no closed part. It is received below the discharge end of the O-ring feeding device 2 and can accommodate the O-rings pushed by the feeding plate 2132; the frame 1 is also provided with a border detection device 11, which is mounted above the material preparation bin 17. In this embodiment, the border detection device 11 is composed of a detection frame and a detection camera. The upper part of the border detection device 11 extends to the top of the material preparation bin 17, and the detector faces the material preparation bin 17 at the extension end to identify the contour of the O-ring in the material preparation bin 17, determine the position of the O-ring border, and feed back the information to the O-ring transfer device 3.

[0068] The O-ring transfer device 3 is located next to the edge detection device 11. This embodiment shows that a raised platform is installed between the O-ring transfer device 3 and the frame 1. The O-ring transfer device 3 includes a transfer drive 31, a first curved arm 32 and a second curved arm 33. The first curved arm 32 is located above the rotating drive 533, one end of which is set on the motor shaft of the transfer drive 31, and the other end is hinged to one end of the second curved arm 33. The second curved arm 33 is located above the first curved arm 32, and a clamping mechanism 13 is provided at the other end away from the hinge. The second curved arm 33 has a built-in drive for driving the clamping mechanism 13, which drives the clamping mechanism 13 to rise and fall. The clamping mechanism 13 is preferably an electric clamp. The transfer drive 31 drives the first curved arm 32 and the second curved arm 33 to move in coordination, driving the clamping mechanism 13 to move to the specified position to open and close.

[0069] See also Figure 5, the support ring positioning device 4 is arranged next to the O-ring transfer device 3, and includes a mounting frame 41 and a support ring assembly 42. The mounting frame 41 includes three layers, and pillars are provided at the four corners between adjacent layers. The upper end of the mounting frame 41 has a tray portion 6, and the upper end surface of the tray portion 6 is used to place the O-ring clamped by the clamping mechanism 13. The tray portion 6 is penetrated by a plurality of movable grooves 7. The multiple movable grooves 7 are distributed circumferentially around the axis of the tray portion 6, and the length direction of each movable groove 7 radiates outward with the same axis.

[0070] The support ring assembly 42 is arranged at the lower part of the material tray part 6, and includes a rotating shaft 423, a support ring driving part 421 and a support ring part 422. The rotating shaft 423 is provided with threaded sections with opposite spiral directions at both ends.

The support ring part 422 has a support ring column 10, which is fixed to the upper end face of the corresponding support ring part 422. The two support ring columns 10 pass through the two movable grooves 7 on the opposite sides and then protrude from the material tray part 6. The support ring driving part 421 drives the rotating shaft 423 to rotate, so that the two support ring parts 422 slide synchronously, driving the support ring columns 10 to slide closer or farther away relative to each other along the corresponding movable grooves 7. The support ring columns 10 on both sides slide away from each other to position the stretched O-ring.

[0071] See also Figure 6 The expansion ring installation device 5 includes an expansion ring assembly 51, an installation assembly 52, a drive assembly 53 and a second installation frame 54. The second installation frame 54 is located next to the first installation frame 41. A sliding platform 18 is slidingly provided on one side of the second installation frame 54. A mounting seat 19 is slidingly provided on the side of the sliding platform 18 away from the second installation frame 54. The sliding direction of the sliding platform 18 is perpendicular to the sliding direction of the mounting seat 19. The drive assembly 53 includes a sliding drive component 1 531 and a sliding drive component 2 532. The sliding drive component 1 531 drives the sliding platform 18 to move between a first position and a second position. When in the first position, the mounting seat 19 is located above the support ring positioning device 4. In the second position, it is located above the oil tank cover. The sliding drive component 2 532 drives the mounting seat 19 to move up and down.

[0072] See also Figure 7 and Figure 9 The expansion ring assembly 51 is installed on the mounting seat 19, which includes an expansion ring base 511, a movable block 512 and a rotating drive member 513. The expansion ring base 534 is rotatably connected to the bottom of the mounting seat 19 and is disc-shaped. A rotating drive member 8 is provided on the mounting seat 19, and its driving end is connected to the expansion ring base 511 to drive the expansion ring base 511 to rotate axially.

[0073] Several movable blocks 512 are slidably arranged at the lower part of the expansion ring base 511 through a slide rail structure. In this embodiment, there are six movable blocks 512. The six movable blocks 512 are distributed at axial intervals around the expansion ring base 511. The position of each movable block 512 corresponds one-to-one to the position distribution of the movable groove 7. The lower end of each movable block 512 protrudes with a movable column 14, and the cross-sectional size of the movable column 14 matches the groove width of the movable groove 7.

[0074] The rotating driving member 513 drives the movable block 512 to slide. The specific driving method is to set a transmission structure 24 in the expansion ring base 534. Figure 8 As shown, it includes gear 1 241, gear 2 242 and spiral chassis 243. Gear 1 241 is arranged on the output shaft of the rotating driving member 513 and is coaxial. Gear 2 242 is meshed with gear 1 241. Gear 2 242 is coaxial with the spiral chassis 243. The spiral chassis 243 is located below gear 2 242. The rotating driving member 513 drives the rotation, and the spiral chassis 243 is driven to rotate by gear 1 241 and gear 2 242. The spiral chassis 2431 is provided with a plurality of guide grooves 25. The positions of the guide grooves 25 correspond one-to-one to the movable blocks 512. Each movable block 512 has a guide portion 26 on the upper end, which is located in the corresponding guide groove 25. The guide portion 26 is guided by the arc-shaped extension direction of the guide groove 25 to move in a preset direction, driving all movable blocks 512 to slide synchronously, so that the movable column 14 expands the O-ring outward.

[0075] See also Figure 7 and Figure 10 The mounting assembly 52 includes a stripping drive member 521 and a stripping plate 522. The stripping plate 522 is located below the expansion ring base 511. The expansion ring base 511 is provided with a number of guide columns 9 that pass through the stripping plate 522 to guide the sliding. The stripping plate 522 is arranged on the output shaft of the push drive member. A number of stripping members 20 are provided below the stripping plate 522. The positions of the stripping members 20 correspond one to one with the movable block 512. Each stripping member 20 is slidably sleeved on the corresponding movable block 512. Each stripping member 20 is sleeved with an elastic member 23. One end of the elastic member 23 rests on the movable block 5 12, and the other end makes the elastic force push the stripping member 20 to have a tendency to press against the lower end surface of the stripping plate 522. When the stripping driving member 521 drives the stripping plate 522, the stripping plate 522 slides downward along the guide column 9, and the stripping plate 522 overcomes the elastic force of each elastic member 23 to compress the elastic member 23, so as to push all the stripping members 20 to move downward synchronously. When the stripping member 20 passes the movable block 512, its lower end pushes the O-ring. When the lower end surface of the stripping member 20 is horizontally lower than the lower end surface of the movable block 512, the O-ring is detached from the movable column 14, and the O-ring is installed.

[0076] The specific working process of this program is as follows:

[0077] The present technical solution prepares a plurality of O-rings on the O-ring feeding device 2, which drives the O-rings to be transported one by one to the preset position on the frame 1, and the O-ring transfer device 3 drives the clamping mechanism 13 at its lower portion to accurately clamp an O-ring located on the frame 1 and transfer it to the support ring positioning device 4. The support ring positioning device 4 then stretches and expands the O-ring and then releases the O-ring. Since the O-ring itself has a certain elastic force, it naturally rebounds to a more central position to determine the positioning of the O-ring before installation. The expansion ring installation device 5 drives the expansion ring assembly 51 at its lower portion to approach the O-ring on the support ring positioning device 4, expand the O-ring, and the O-ring has a certain elastic force. The sliding drive part 2 532 drives the expansion ring installation device 5 to slide close to the oil tank cover. The expansion ring installation device 5 puts the O-ring on the outside of the oil pipe cover to complete the O-ring installation, automatically install the O-ring, reduce the installation difficulty, and thus improve the installation quality of the O-ring.
