The most significant feature of deep well pumps is that the motor and pump are integrated into one unit. Deep well pumps are widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Deep well pumps contain various parts such as rotors. Before starting the pump, the suction pipe and the pump body must be filled with liquid. Therefore, when the end cover is fastened to the rotor, it is necessary to seal and isolate the rotor from the liquid. The oil seal installed inside the end cover abuts against the rotor when the end cover is fastened to achieve rotor sealing. In addition, an O-ring is also required to further seal the end cover. Currently, the oil seal and O-ring are installed manually. Manual installation requires high time and financial costs and has low efficiency.

[0015] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0016] 1. The end cap feeding device designed in this technical solution can automatically transfer the end cap to the transfer device, the oil seal feeding device can lubricate the oil seal and install the oil seal on the end cap, the O-ring feeding device can install the O-ring on the end cap, and at the same time the transfer device can transfer the processed end cap, realizing assembly line operation. Multiple devices work together to complete the assembly of the end cap, which greatly saves labor costs and improves assembly efficiency.

[0017] 2. The end cap feeding device designed in this technical solution has the function of rapid feeding. The end cap lifting mechanism moves up and down, lifting the end caps by lifting the support base. After any set of end caps on the end cap feeding rack has been transferred, the end cap lifting mechanism continues to move downward through the notch until it reaches the bottom of the end cap feeding tray. At this time, the end cap feeding tray rotates, causing the next end cap feeding rack full of end caps to move above the end cap lifting mechanism. The end cap lifting mechanism then rises again to lift the end caps. This setting eliminates the need for the end cap lifting device to perform forward and backward insertion and insertion under the end caps, saving the lifting time of the end caps, simplifying the equipment, and reducing costs.

[0018] 3. The oil seal feeding device designed in this technical solution has the function of quickly immersing and draining oil seals. After the oil seal is immersed in oil, it is lifted by the oil seal lifting part until it is removed from the lubricating oil. While the oil seal is draining, the oil seal transfer module can work at the same time, which saves the time of oil seal feeding and draining the oil seal. The oil seal picking shaft is designed to be tightly fitted with the oil seal. When the oil seal picking shaft moves downward, it can grab the oil seal. When the oil seal picking shaft moves upward, it can automatically detach the oil seal, simplifying the previous steps of grabbing the oil seal by hand.

[0019] 4. The O-ring feeding device designed in this technical solution has the function of automatically expanding and installing O-rings. After the O-ring expansion mechanism expands the O-ring, the O-ring installation mechanism grabs the O-ring and installs it on the end cover. During the expansion of the O-ring, the force between the inclined planes achieves rapid and stable expansion of the O-ring. After expansion, the O-ring is transferred to the mounting cylinder through the structure of the clearance opening. This method is simple and fast and can effectively protect the O-ring from damage.

[0041] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0042] A deep well pump end cap assembly machine for installing oil seals 12 and O-rings 13 onto end caps 11 includes: a main frame 1; a transfer device 2, mounted on the main frame 1, for transferring the end caps of the deep well pump; an end cap feeding device 3, mounted beside the main frame 1, for feeding the end caps onto the transfer device 2; an oil seal feeding device 4, mounted on the main frame 1, for lubricating the oil seals and installing them inside the end caps; an O-ring feeding device 5, mounted on the main frame 1, for installing O-rings onto the end caps; wherein the transfer device 2 can sequentially transfer the end caps to below the oil seal feeding device 4 and the O-ring feeding device 5 to complete the installation of the oil seals and O-rings; a chain plate device 6, for transferring the processed end caps; and a robotic arm device 7, for clamping and transferring the processed end caps from the transfer station 25 onto the chain plate device 6.

[0043] like Figure 1-4 As shown, the oil seal needs to be installed in the middle of the end cover, and the O-ring needs to be installed around the perimeter of the end cover. The transfer device 2, end cover feeding device 3, oil seal feeding device 4, O-ring feeding device 5, robotic arm device 7, and chain plate device 6 work together to form a production line for processing and assembling deep well pump end covers. The end cover feeding device 3, oil seal feeding device 4, O-ring feeding device 5, and robotic arm device 7 are arranged around the transfer device 2. The transfer device 2 includes: a transfer motor, which is located below the main frame 1; and a rotating disk 21, which is located above the main frame 1 and connected to the output end of the transfer motor, and has transfer station 1 22, transfer station 23, transfer station 3 24, and transfer station 4 25 on it; wherein, the transfer motor controls the rotation... The rotating disc 21 rotates continuously, causing the end caps on transfer stations 1 (22), 23, 24, and 25 to be processed in an assembly line. The transfer device 2 is located above the main frame 1. Transfer station 1 (22) receives the end caps transferred by the end cap feeding device 3. The oil seal feeding device 4 assembles the oil seals on the end caps at transfer station 2 (23). The O-ring feeding device 5 assembles the O-rings on the end caps at transfer station 3 (24). After processing, the end caps are transferred to transfer station 4 (25) and picked up by the robotic arm device 7 and transferred to the chain plate device 6. This achieves fully automated processing of the end caps. The various devices work together to assemble the end caps, which greatly improves the assembly production efficiency and reduces labor costs.

[0044] Preferably, the end cap feeding device 3 includes: an end cap feeding platform 31, on which an end cap feeding tray 32 is provided, the end cap feeding tray 32 having a plurality of notches 33; an end cap feeding rack 34, which is provided on the end cap feeding tray 32, and a bearing base 35 is provided on it, with all end caps placed on the bearing base 35; an end cap lifting mechanism 36, which is provided on the main frame 1, for lifting the bearing base 35 to lift the end caps; and an end cap conveying mechanism 37, which is provided on the main frame 1, for clamping the end caps after lifting to a certain height and feeding them to the transfer device 2; wherein, the end cap lifting mechanism 36 passes through the notches 33 and abuts against the bottom surface of the bearing base 35, and the bearing base 35 moves up and down by its own movement.

[0045] Depend on Figure 3-5 As shown, the end cap loading platform 31 is located beside the main frame 1, and a motor for driving the end cap loading tray 32 is located below it. Multiple end cap loading racks 34 are mounted on the end cap loading tray 32. Each end cap loading rack 34 is a cylindrical rod with a vertically movable support base 35 at its lower end. The end caps are hollowed out in the middle and can be fitted onto the end cap loading rack 34 and placed on the support base 35. The end caps can be lifted by controlling the vertical movement of the support base 35. Several notches 33 are provided on the end cap loading tray 32, with two notches corresponding to each end cap loading rack 34. The end cap lifting mechanism 36 includes a lifting motor, a lead screw, a slide rail, and a lifting plate 38. The lifting motor drives the lifting plate 38 to move up and down on the slide rail via the lead screw. The lifting plate 38 can pass through the notches 33 and movably abut against the support base 35. The lifting plate 38 can drive the support base 35 to move. After each end cap is transferred, the lifting plate 38 rises by the height of one end cap, and the transfer continues. Next, after the end cap on one of the end cap loading racks 34 is processed, the lifting plate 38 passes through the notch 33 and stops below the end cap loading tray 32. Then, the other end cap loading rack 34 rotates to above the lifting plate 38, and the lifting plate 38 re-enters the notch 33 and abuts against the support base 35, continuing to lift the end cap on this end cap loading rack 34. The end cap conveying mechanism 37 includes a slide rail and a gripper that can be transported horizontally and vertically. The gripper is used to grab the lifted end cap. The end cap conveying mechanism 37 is a conventional structure and will not be described in detail here. The end cap is placed on the transfer station 22 by the gripper. The end cap loading device 3 realizes the automated loading of end caps. When lifting the end cap, the lifting plate 38 does not need to move back and forth to insert under the end cap. The design of the notch 33 allows the lifting plate 38 to lift the end cap by only moving up and down vertically. Because the power component for back and forth movement can be omitted, the components of the device are simplified and the overall size of the device is reduced.

[0046] Preferably, the oil seal feeding device 4 includes: an oil seal conveying mechanism 41, which is mounted on the main frame 1 and used to transfer the oil seal to the transfer device 2; and an oil seal lubrication mechanism 42, which is mounted on the oil seal conveying mechanism 41 and used to lubricate the oil seal. The oil seal conveying mechanism 41 includes: an oil seal feeding frame 411, mounted on the main frame 1; an oil seal transfer module 412, mounted on the oil seal feeding frame 411 and used to transfer the oil seal; at least one oil seal picking module 413, mounted on the oil seal transfer module 412; and an oil seal vibrating feeding plate 414, on which an oil seal feeding slide 415 is connected, the rear end of which is positioned below the oil seal picking module 413. The oil seal picking module 413 picks up the oil seal on the oil seal feeding slide 415 and transfers it to the oil seal lubrication mechanism 42. After lubrication, the oil seal is transferred to the transfer device 2.

[0047] like Figure 6-8 As shown, the oil seal lubrication mechanism 42 is installed inside the oil seal conveying mechanism 41. The oil seal conveying mechanism 41 is used to transfer the oil seal, and the oil seal lubrication mechanism 42 is used to lubricate the oil seal. Together, they can transfer the oil seal to the upper part of the transfer station 23 and install it on the end cover. The oil seal feeding device 4 includes the following steps: the oil seal picking module 413 picks up the oil seal, then transfers the oil seal to the oil seal lubrication mechanism 42 for lubrication and oil draining, and then picks up the oil seal again and installs it on the end cover. Therefore, by setting two oil seal picking modules 41... 3. They work independently at the same time. One of them picks up the oil seal and transfers it to the oil seal lubrication mechanism 42, while the other picks up the oil seal and transfers it to the transfer station 23. While the two are working, the oil seal lubrication mechanism 42 can complete the oil soaking and oil draining work, saving processing time. The oil seal transfer module 412 is used to control the horizontal and vertical movement of the oil seal picking module 413. It includes a slide rail set on the top of the oil seal loading frame 411, a slide seat set on the slide rail, and a cylinder connected to the slide seat. This structure is existing technology and will not be described in detail here.

[0048] Preferably, the oil seal picking module 413 includes: an oil seal picking cylinder 4131, which is mounted on the oil seal feeding frame 411; an oil seal picking shaft 4132, which is mounted on the output end of the oil seal picking cylinder 4131; and an oil seal exit sleeve 4133, which is sleeved outside the oil seal picking shaft 4132 and has its upper end mounted on the oil seal feeding frame 411. The portion of the oil seal picking shaft 4132 extending out of the oil seal exit sleeve 4133 is inserted into the through hole of the oil seal to pick up the oil seal. The oil seal abuts against the oil seal exit sleeve 4133. When the oil seal picking shaft 4132 extends and retracts into the sleeve of the oil seal picking shaft 4132, the oil seal is pushed out by the oil seal exit sleeve 4133.

[0049] like Figure 6-8As shown, the inner diameter of the oil seal picking shaft 4132 is matched with the inner diameter of the mounting hole on the oil seal. Therefore, the oil seal can be tightly fitted onto the oil seal picking shaft 4132. The oil seal can be picked up by directly inserting the oil seal into the oil seal through the oil seal picking shaft 4132. The oil seal exit sleeve 4133 is sleeved on the outside of the oil seal picking shaft 4132, and its upper end is fixedly set on the oil seal feeding frame 411. Therefore, the oil seal picking shaft 4132 can extend and retract into the oil seal exit sleeve 4133. When the oil seal is tightly fitted onto the oil seal picking shaft 4132, the oil seal part abuts against the oil seal exit sleeve 4133, that is, the inner diameter of the oil seal exit sleeve 4133 is smaller than the inner diameter of the oil seal. This design can quickly grip the oil seal without the need for a robotic arm or similar equipment, thus simplifying the components and size of the device, while ensuring that the oil seal will not be damaged by the robotic arm gripping it.

[0050] Preferably, the oil seal lubrication mechanism 42 includes: a mounting base 421, which is mounted on the oil seal feeding frame 411 via a mounting column 422, and an oil box 423 is mounted on it, the oil box 423 being filled with lubricating oil; an oil seal lifting cylinder 424, which is located below the main frame 1; an oil seal lifting part 425, which is located at the output end of the oil seal lifting cylinder 424 and is movably sleeved outside the mounting column 422; and an oil seal positioning mold base 426, which is located on the oil seal lifting part 425; wherein, part of the oil seal lifting part 425 is located below the oil box 423, and part of it bends along the opening of the oil box 423 to enter the oil box 423, so that the oil seal positioning mold base 426 can move up and down in the oil box 423 following the oil seal lifting part 425 to complete the oil immersion and oil draining of the oil seal.

[0051] like Figure 6-8As shown, the mounting base 421 is mounted above the main frame 1 via the mounting column 422. The oil box 423 is fixedly mounted on the mounting base 421. An oil seal lifting part 425 is provided outside the oil box 423, which is arranged around the oil box 423 along its length and is movably sleeved on the mounting column 422. Therefore, the oil seal lifting part 425 can be vertically raised and lowered along the mounting column 422. The mounting column 422 is used to support the mounting oil box 423 and also to guide the movement of the oil seal lifting part 425. The oil seal lifting part 425 is formed by connecting multiple straight plates to form a "concave" shape, with the lower straight plate sleeved on... Outside the mounting column 422, left and right straight plates are respectively connected upwards to both ends of the lower straight plate. The left and right straight plates are located near the side wall of the oil box 423. Short plates are connected to the left and right straight plates towards the oil box 423. Positioning plates are installed in the short plates extending into the oil box 423. The oil seal positioning mold base 426 is set on the positioning plate. The positioning plate can move up and down in the oil box 423 by lifting the lower straight plate. When the positioning plate is below the lubricating oil, the oil seal is immersed in oil. When the positioning plate is above the lubricating oil, the oil seal is drained. The oil seal lifting part 425... The lower straight plate is located at the output end of the oil seal lifting cylinder 424. When the oil seal lifting part 425 is working, the oil box 423 and the mounting base 421 remain fixed. Only the oil seal lifting part 425 needs to move to complete the oil immersion and draining. When the oil seal picking shaft 4132 transfers the oil seal into the oil box 423, the oil seal lifting part 425 rises in advance to prepare to receive the oil seal. After receiving the oil seal, the oil seal picking shaft 4132 returns to continue picking up materials. At this time, the oil seal lifting part 425 descends to lubricate the oil seal. After lubrication, the oil seal is lifted to drain the oil. During the sealing process, another oil seal picking shaft 4132 moves above the oil box 423. Then, both oil seal picking shafts 4132 descend simultaneously, one picking up the oil seal and the other picking up the lubricated oil seal. The lubricated oil seal is then transferred to the transfer station 23, while the unlubricated oil seal is transferred to the oil box 423 for reciprocating operation. This setup is simple in structure, eliminates the need for the oil seal picking shaft 4132 to enter the lubricating oil, protects the service life of the mechanical equipment, and rationally plans the work tasks, thus doubling the efficiency.

[0052] Preferably, the O-ring feeding device 5 includes: an O-ring transfer mechanism 51, which is mounted on the main frame 1 for transferring O-rings; an O-ring expansion mechanism 52, which is mounted on the main frame 1 for expanding O-rings; an O-ring mounting mechanism 53, which is mounted on the O-ring transfer mechanism 51 for mounting the expanded O-rings on end caps; and an O-ring vibrating feeding plate 54, on which an O-ring feeding slide 55 is connected, the rear end of which is located below the O-ring transfer mechanism 51.

[0053] like Figure 9As shown, the O-ring transfer mechanism 51, the O-ring mounting mechanism 53, and the O-ring expansion mechanism 52 cooperate to complete the transfer and processing of the O-ring. The O-ring transfer mechanism 51 includes a first transfer module 511 and a second transfer module 512. The first transfer module 511 is used to drive the O-ring mounting mechanism 53 to move horizontally, and the second transfer module 512 is used to drive the O-ring mounting mechanism 53 to move vertically. The O-ring is first transported to the O-ring transfer mechanism 51 by the O-ring vibrating feeding plate 54 through the O-ring feeding slide 55. After the O-ring mounting mechanism 53 picks up the O-ring, it is transferred to the O-ring expansion mechanism 52. At the same time, the O-ring mounting mechanism 53, which is placed above the O-ring expansion mechanism 52, transfers the expanded O-ring to the transfer station 24 and installs it on the end cap. Therefore, the O-ring transfer mechanism 51 can make the transfer and processing of the O-ring synchronized. The first transfer module 511 and the second transfer module 512 are both driven by cylinders to realize the transfer of O-rings.

[0054] Preferably, the O-ring mounting mechanism 53 includes a gripping module 531 and an mounting module 532. The gripping module 531 is used to mount the O-ring on the stretching position, and the mounting module 532 is used to mount the expanded O-ring on the end cap.

[0055] like Figure 9 As shown, the gripping module 531 includes two grippers and a cylinder for controlling the grippers. An O-ring feeding base is provided at the end of the O-ring feeding slide. Both ends of this base are provided with clamping holes. The cylinder controls the grippers to extend into the clamping holes to grip the O-ring, which can ensure that the O-ring is subjected to uniform force on both sides and that the O-ring maintains its circular shape during transfer. After the gripping module 531 grips the O-ring, the O-ring transfer module drives the gripping module 531 to move, transferring the O-ring to the top of the O-ring expansion mechanism 52. Then, the grippers are released, allowing the O-ring to fall onto the O-ring expansion mechanism 52, where it waits for the O-ring expansion mechanism 52 to expand the O-ring.

[0056] Preferably, the O-ring expansion mechanism 52 includes: an expansion ring fixing base 521 with a plurality of movable areas 522 thereon, and a plurality of expansion ring slide rails 523 disposed within the movable areas 522; a plurality of inclined push sliders 524 disposed on the corresponding expansion ring slide rails 523, and having their ends bent to form stretching portions 525 for mounting O-rings, all of the stretching portions 525 cooperating to form a stretching position, the inclined push sliders 524 surrounding to form an ejection area 526; and an ejector 527. Its movement is located within the ejection area 526 and has several inclined surfaces adapted to the inclined ejector slider 524; ejection cylinder 528 is used to drive the ejector 527 to extend and retract; reset member 529 is used to control all inclined ejector sliders 524 to reset; wherein, the ejection cylinder 528 drives the ejector 527 to make the inclined ejector slider 524 slide, thereby expanding the O-ring; when the ejection cylinder 528 drives the ejector 527 to reset, the reset member 529 controls the inclined ejector slider 524 to reset.

[0057] like Figure 10-12As shown, the expansion ring fixing base 521 is provided with multiple expansion ring slide rails 523 and inclined slide blocks 524. The number of inclined slide blocks 524 is at least three. Only when three or more inclined slide blocks 524 work together can the O-ring be expanded. The number of inclined slide blocks 524 is more suitable between six and eight. The more inclined slide blocks 524 there are, the more evenly the force is distributed. The expansion ring slide rails 523 all slide back and forth towards the center of the fixing base. The tensioning part 525 is provided on the inner end side of the inclined slide block 524. The tensioning part 525 of each inclined slide block 524 is... The interlocking components are used to fix the O-ring. When the angled slide blocks 524 move outward simultaneously, the O-ring is stretched and expanded. A reset member 529 is provided on the outer end of the angled slide block 524. The reset member 529 is made of rubber band or ring spring and is located in the snap-fit ​​groove. When the angled slide block 524 is pushed out by the ejector 527, the reset member 529 is stretched simultaneously, causing the angled slide blocks 524 to tend to move closer together. The reset member 529 has various structures, which are used to make the angled slide block 524 and the ejector 527 have interrelated movements, that is, when the ejector is pushed out... When component 527 is reset, reset component 529 can drive the inclined slide block 524 to reset. All structures or devices with this function can be called reset component 529. The center of the fixed base has a channel for the ejector component 527 to move. The inclined slide block 524 and the ejector component 527 have mutually compatible and movable contact inclined surfaces. Therefore, when the ejector component 527 moves upward, it can push out the inclined slide block 524 horizontally to complete the expansion task of the O-ring. The mounting cylinder 537 is set on the connecting plate 533, and the connecting plate 533 is driven by the O-ring transfer mechanism 51 to move up and down. When the lower end of the O-ring is placed in the stretch position and expanded, the mounting cylinder 537 moves downward into the O-ring. At this time, the stretching part 525 on the inclined slide block 524 can move forward or backward freely along the clearance opening 539. When the O-ring is stretched into place, the inclined slide block 524 resets. At this time, the stretching part 525 on the inclined slide block 524 retracts synchronously along the clearance opening 539. After the O-ring comes into contact with the mounting cylinder 537, it disengages from the stretching part 525 and contracts and fits around the protrusion 538 at the lower end of the mounting cylinder 537 through its own elasticity, thus completing the gripping of the expanded O-ring.

[0058] Preferably, the mounting module 532 is used to mount the expanded O-ring onto the end cap. The mounting module 532 includes: a connecting plate 533, which is fixedly mounted on the O-ring transfer mechanism 51 and has a mounting cylinder 534 mounted thereon; a transmission part 535, which is mounted on the connecting plate 533 and connected to the output end of the mounting cylinder 534; a movable plate 536, which is located at the lower end of the transmission part 535 and has a through hole on its surface; a mounting cylinder 537, which is located below the connecting plate 533 and placed inside the through hole, and whose outer diameter is larger than the outer diameter of the position where the O-ring is mounted on the end cap; and several protrusions 538, which... The protrusion is located at the lower end of the mounting cylinder 537, and an avoidance opening 539 is formed between adjacent protrusions 538. When the O-ring is expanded, the transfer mechanism controls the mounting cylinder 537 to descend and extend into the O-ring. At this time, the inclined top slider 524 is reset, and the stretching part 525 retracts along the avoidance opening 539 to the ejection area 526, so that the O-ring is fitted onto the mounting cylinder 537. When the mounting cylinder 537 is placed above the end cover, the mounting cylinder 534 controls the movable plate 536 through the transmission part 535 to push the O-ring fitted outside the mounting cylinder 537, so that the O-ring is detached from the mounting cylinder 537 and installed on the end cover.

[0059] like Figure 12-14 As shown, when the installation module 532 moves above the transfer station 24, the movable plate 536 pushes the O-ring so that the O-ring is installed in the installation groove 14 opened on the end cover. The O-ring is fitted on the lower end of the installation cylinder 537. When the installation cylinder 537 is aligned with the end cover, the upper surface of the end cover can slightly enter the inner cavity of the installation cylinder 537, or it can abut against the lower end face of the installation cylinder 537. The outer diameter of the lower end of the installation cylinder 537 is not less than the outer diameter of the plane where the installation groove 14 is located on the end cover, so as to ensure that the O-ring can slide smoothly into the installation groove 14. The installation cylinder 534 works to control the movable plate 536 to move up and down through the transmission part 535. The movable plate 536 moves down to push the O-ring down until it is disengaged from the installation cylinder 537 and finally installed in the installation groove 14. The installation of the O-ring is completed on the transfer station 24.
