Description

Technical Field

[0001] This patent belongs to the field of automated equipment technology, specifically referring to an assembly line for the upper end cover of a deep well pump. Background Technology

[0002] A deep well pump mainly consists of a pump body and a deep well pump motor. The deep well pump motor provides power to the pump body during operation, enabling the pump to function normally. A deep well pump motor typically includes components such as a motor housing and end caps, which must be assembled one by one to obtain a complete motor.

[0003] With the development of technology, mechanized production operations have been widely used, and the assembly of motors can also be mechanized. During assembly, the components to be assembled are first placed on tooling, and then the deep well pump's top cover and sand-proof structure are installed sequentially. After installation, the deep well pump is sealed with oil. In general, the existing deep well pump assembly process is complex and inefficient, necessitating a streamlined assembly line for the deep well pump's top cover that can effectively improve product manufacturing speed.

[0021] A crank is provided at one end of the adapter shaft, and the crank is connected to a first linear actuator that drives the crank to swing.

[0022] Furthermore, the conveying assembly includes a longitudinal conveying section and a transverse conveying section connected to each other, and several toolings are conveyed sequentially on the longitudinal conveying section and the transverse conveying section; the longitudinal conveying section and the transverse conveying section are each provided with the rivet assembly unit, which is used to set rivets on the left and right ends and the front and rear ends of the deep well pump body respectively.

[0023] Furthermore, the sand-proof structure assembly device includes:

[0024] The first assembly station, located on one side of the conveying assembly, is used to install the sand-proof seat onto the deep well pump body; and

[0025] The second assembly station is located on one side of the conveying component and behind the first assembly station; the second assembly station is equipped with the first material handling component and the second material handling component.

During the installation process, the deep well pump body is always fixed on the tooling. Therefore, this patent achieves rivet installation on multiple aspects of the deep well pump body without disassembling the deep well pump body by setting up multiple conveying components and rivet assembly units with different orientations.

[0043] 3. This patent adapts the assembly of deep well pump bodies of different sizes by setting up lifting and translation mechanisms on the mounting bracket in the rivet assembly unit.

[0044] 4. This patent achieves the rotation of the clamping hand by means of a rotating frame, so that the feeding seat can be installed below the clamping hand to obtain sufficient space for installation; and when the feeding seat is installed below the clamping hand, the feeding seat only needs to be used to convey the rivets through a common linear vibrator structure, which reduces the difficulty of setting up the feeding seat.

[0045] 5. The conveying component of this patent is equipped with the aforementioned rivet assembly unit on both sides, which can simultaneously rivet the two sides of the deep well pump body, greatly accelerating the rivet installation efficiency.

[0046] 6. This patent converts the linear pushing structure of the first linear pusher into the rotational action of the clamping hand through a crank structure. Its rotational structure is stable and easy to assemble. In addition, a limit block is provided on the adapter shaft of the clamping hand. The limit block restricts the maximum swing angle of the clamping hand, thereby increasing the stability of the clamping hand's operation. Attached Figure Description

[0082] The present patent will be further described below with reference to specific embodiments:

[0083] A deep well pump top cover assembly line, such as Figure 1 As shown, the manufacturing production line 1 is generally square-shaped and has a feeding area 11, an upper end cap 241 assembly area 12, a sand-proof structure assembly area, and an oil injection area 14 arranged sequentially on it. Workers 15 are arranged at the feeding area 11. Workers 15 place the deep well pump body 24 on the conveying assembly 2 and place the upper end cap 241 on the deep well pump body 24. Then, the conveying assembly 2 passes through the upper end cap 241 assembly area 12, the sand-proof structure assembly area, and the oil injection area 14 in sequence to fix the upper end cap 241 and the sand-proof structure on the deep well pump body 24 in sequence and inject oil to seal it.

[0084] The upper end cover fastening device is located at the assembly area 12 of the upper end cover 241, and includes a stamping assembly 3 and a rivet 242 assembly unit. The conveying assembly 2 conveys several tooling fixtures 21, on which the deep well pump body 24 is mounted. Figure 1 , 3 As shown, the conveying component 2 in this patent not only conveys the deep well pump body 24 to the upper end cap fastening device, but also conveys the deep well pump body 24 to the device in the sand-proof structure assembly area and the oil injection area 14. The conveying component 2 is generally square, and includes two longitudinal conveying parts 22 and two transverse conveying parts 23. The two longitudinal conveying parts 22 and the two transverse conveying parts 23 are connected in sequence to form a square conveying structure. The upper end cap 241 assembly area 12, the sand-proof structure assembly area and the oil injection area 14 are arranged in sequence along the conveying component 2. The tooling 21 moves along the conveying component 2, and the deep well pump body 24 located on the tooling 21 will pass through the upper end cap 241 assembly area 12, the sand-proof structure assembly area and the oil injection area 14 in sequence to assemble the deep well pump.

[0085] The stamping assembly 3 is positioned above the conveying assembly 2 and is used to stamp the upper end cover 241 located on the deep well pump body 24. Figure 3 , 4As shown in the figure, the stamping assembly 3 includes a stamping bracket 31, a stamping top plate 32 on the stamping bracket 31, and a vertically arranged third linear pusher 33 on the stamping top plate 32. The stamping head 34 is driven by the third linear pusher 33. The deep well pump body 24, on which the upper end cover 241 is placed, is conveyed to the area below the stamping head 34 by the conveying assembly 2. At this time, the third linear pusher 33 drives the stamping head 34 to press the upper end cover 241 downward, thereby fixing the upper end cover 241 onto the deep well pump body 24.

[0086] The rivet 242 assembly unit includes an assembly bracket 41, a feed seat 42, a clamping hand 43, and a locking electric screwdriver 44, as shown below. Figure 4 , 5 As shown in this patent, rivet 242 assembly units are provided on both sides of the conveying component 2, for simultaneously installing and locking the rivets 242 onto both sides of the deep well pump body 24. In this patent, fastening grooves 243 are provided on the front and rear sides and the left and right sides of the deep well pump body 24. The fastening grooves 243 are connected to the upper end cover 241 located in the deep well pump body 24. The fastening grooves 243 are used to install the rivets 242, which abut against the upper end cover 241 in the fastening grooves 243. Fasteners can be set in the rivets 242 to fix them to the deep well pump body 24. The rivets 242 are used to radially position the upper end cover 241 and the deep well pump body 24, preventing them from shifting.

[0087] like Figure 4 , 5 As shown, the assembly bracket 41 includes a first base 411 and a lifting mechanism 412 mounted on the first base 411. The lifting mechanism 412 moves the assembly bracket vertically, thereby driving a translation mechanism 413. The translation mechanism 413 then moves the clamping hand 43 and the locking electric screwdriver 44 laterally. (Reference) Figure 5The lifting mechanism 412 includes a lifting seat 4121 fixed on a first base 411. The lifting seat 4121 has several guide holes, and a guide rod 4122 is provided in the guide holes. A translation mechanism 413 is connected to the guide rod 4122. The lower end of the guide rod 4122 is also provided with a lifting drive plate 4123. A lead screw structure 4124 is provided between the lifting drive plate 4123 and the lower lifting seat 4121, and a motor that drives the lead screw structure 4124 to work. The motor is connected to the lead screw structure 4124 through a synchronous belt structure and drives it to move. The lead screw structure 4124 drives the lifting drive plate 4123 to move relative to the lower lifting seat 4121, and causes the guide rod 4122 to move along the guide holes, thereby driving the translation mechanism 413 connected to the upper end of the guide rod 4122 to rise and fall. The translation mechanism 413 includes a translation base plate 4131, which connects to the guide rod 4122. The translation base plate 4131 has a translation slide rail 4132 and a translation slider. A mounting plate 45 is connected to the translation slider, providing installation space. The clamping hand 43 and locking electric screwdriver 44 are mounted on the mounting plate 45. A cylinder connecting to the mounting plate 45 is also provided on one side of the translation base plate 4131. During operation, the positions of the clamping hand 43 and locking electric screwdriver 44 can be adjusted using the lifting mechanism 412 and the translation mechanism 413 to adapt to the assembly of deep well pumps of different shapes and sizes, increasing assembly flexibility.

[0088] The clamping hand 43 is mounted on the assembly bracket 41 and is used to grab the rivet 242 in the feeding seat 42 and deliver it to the deep well pump body 24; the feeding seat 42 is generally located on one side of the assembly bracket 41 and is used to transport the rivet 242. Figure 5 As shown, the feeding seat 42 is located at the front end of the lifting mechanism 412 and below the clamping hand 43. In this patent, the feeding seat 42 is specifically a linear vibrator, used to feed the rivets 242 one by one to one side of the feeding seat 42 for the clamping hand 43 to grip. The upper side of the linear vibrator is open. At this time, the feeding seat 42 is located below the clamping hand 43, and the conveying assembly 2 is located in front of the clamping hand 43. Therefore, the assembly bracket 41 in this patent is provided with a rotating frame 46, which rotatably connects to the clamping hand 43, so that the clamping hand 43 rotates around the rotating frame 46, so that the clamping hand 43 can grip the material towards the feeding seat 42 below it, or feed the material towards the tooling 21.

[0089] Combination Figure 5-7As shown, the rotating frame 46 is mounted on the mounting plate 45. The rotating frame 46 is U-shaped, and has adapter holes on both sides. Bearings 461 are installed in the adapter holes. The clamping hand 43 has adapter shafts on both sides that pass through the adapter holes. A crank 462 is provided on one end of the adapter shaft, and a first linear actuator 463 that drives the crank 462 to swing is connected to the crank 462.

[0090] like Figure 6 As shown, the clamping hand 43 in this patent includes a second linear pusher 431, a telescopic picking rod 432, and a clamping plate 433. In this embodiment, the clamping hand 43 further includes a support plate 434, with adapter shafts on both sides of the support plate 434 rotatably connected to the rotating frame 46; the second linear pusher 431 is fixed on the support plate 434, and the second linear pusher 431 is driven to rotate by the rotatable connection between the support plate 434 and the rotating frame 46. The second linear pusher 431 is specifically a cylinder, with the telescopic picking rod 432 fixed to its drive end, used to drive the telescopic picking rod 432 to move; as Figure 6 As shown, a telescopic guide rail is also provided on the front end of the support plate 434, and a telescopic slide plate 4341 is provided on the telescopic guide rail. The telescopic material picking rod 432 is fixed on the telescopic slide plate 4341. The telescopic slide plate 4341 is driven to move along the telescopic guide rail by the second linear pusher 431, thereby moving the telescopic material picking rod 432. The material clamping plate 433 is formed on the front end of the support plate 434 and is perpendicularly connected to the support plate 434. The material clamping plate 433 is provided with a material clamping hole 4331. In this embodiment, the material clamping plate 433 is formed on the front end of the telescopic slide plate 4341. In other embodiments, the telescopic slide plate 4341 and the telescopic guide rail can be provided, and the telescopic material picking rod 432 can be directly connected by the second linear pusher 431. The advantage of providing the telescopic guide rail is that it increases the stability of the telescopic material picking rod 432 when it is driven. When the telescopic slide plate 4341 and the telescopic guide rail are not provided, the material clamping plate 433 can be directly installed on the support plate 434.

[0091] The telescopic material-grabbing rod 432 is used to extend through the clamping hole 4331 to grab the rivet 242, or to retract so that the rivet 242 abuts against the clamping plate 433 and falls off. In this patent, the rivet 242 is a ring-shaped component with a through hole in its center. The telescopic material-grabbing rod 432 includes a telescopic cylinder 4342 fixed to the telescopic sliding plate 4341. The telescopic cylinder 4342 drives a telescopic push rod 4343, which, driven by the cylinder 4342, can be inserted forward into the through hole of the rivet 242, fixing the rivet 242 to the end of the telescopic material-grabbing rod 432 through an interference fit. When the rivet 242 is fixed at the end of the telescopic material-grabbing rod 432, the entire clamping hand 4... 3. Then rotate towards the deep well pump body 24. At this time, the second linear pusher 431 moves again, driving the entire telescopic material-retrieving rod 432 forward, so that the rivet 242 located at the end of the telescopic material-retrieving rod 432 is engaged in the deep well pump body 24. Then the telescopic material-retrieving rod 432 retracts. Since the telescopic material-retrieving rod 432 is connected to the rivet 242 by passing through the clamping plate 433, the rivet 242 will abut against the clamping plate 433 and fall off the telescopic material-retrieving rod 432, so that the rivet 242 is successfully installed in the deep well pump body 24.

[0092] The clamping hand 43 rotates via the first linear pusher 463, such as Figure 6 , 7 As shown, since the support plate 434 of the clamping hand 43 has adapter shafts on both sides for insertion into the adapter holes, a crank 462 can be provided on the end of the adapter shaft. The first linear pusher 463 is fixed on the mounting plate 45 and connected to the crank 462. The first linear pusher 463 is specifically a cylinder, which is connected to one end of the crank 462 and rotatably connected to the crank 462. During operation, the first linear pusher 463 moves forward, causing the crank 462 to swing, thereby driving the adapter shaft to rotate, which in turn drives the clamping hand 43 to rotate, realizing the steering of the clamping hand 43.

[0093] Since the feeding seat 42 in this patent is located below the assembly bracket 41, the clamping hand 43 needs to be rotated to a vertical position so that the clamping hand 43 is opposite to the rivet 242 on the feeding seat 42 to facilitate clamping; then the clamping hand 43 is rotated to a horizontal position so that the clamping hand 43 is opposite to the deep well pump body 24 to facilitate feeding the rivet 242.

[0094] Furthermore, a limiting block 464 is provided on the other end of the adapter shaft, and a first limiting part 465 and a second limiting part 466 are provided on both sides of the limiting block 464. When the adapter shaft rotates, the rotating frame 46 swings to and abuts against the first limiting part 465 or the second limiting part 466 for limiting. Figure 7 As shown, the rotating frame 46 is a connecting handle. The first limiting part 465 and the second limiting part 466 are disposed on the rotating frame 46. Specifically, they are two air springs respectively disposed in front of and above the adapter shaft. When the adapter shaft rotates, it will drive the limiting block 464 to swing, so that the limiting block 464 abuts against the first limiting part 465 or the second limiting part 466 and is limited, until the adapter shaft has rotated the maximum distance.

[0095] After the rivet 242 is installed, the locking electric screwdriver 44, driven by the translation mechanism 413, is positioned opposite the rivet 242 to install the fastener. The fastener in this patent is a screw, which is fed by a screwdriver. The locking electric screwdriver 44 is connected to a linear actuator that drives it to extend. The linear actuator pushes the locking electric screwdriver 44 forward to lock the screw into the rivet 242, thus achieving the connection.

[0096] The sand-proof structure assembly device is located on the rear side of the upper end cap fastening device; such as Figure 2 As shown in the patent, the sand-proof structure consists of a sand-proof seat 244, a sand-proof pad 245, and a sand-proof cap 246. The sand-proof structure assembly device is located in the sand-proof component assembly area 13, which includes a first assembly station 53 and a second assembly station 54. The first assembly station 53 is used to install the sand-proof seat 244 onto the deep well pump body 24. The second assembly station 54 is located on one side of the conveying component 2 and behind the first assembly station 53. The second assembly station 54 is provided with a first material-retrieving component 543 and a second material-retrieving component 544. The first material-retrieving component 543 and the second material-retrieving component 544 are respectively used to grab the sand-proof pad 245 and the sand-proof cap 246 onto the deep well pump body 24.

[0097] like Figure 9 , 11 As shown, the first assembly station 53 includes a first frame 531, on which a first sliding mechanism 532 is provided. A first linear drive 571 and a second linear drive 573 are driven by the first sliding mechanism 532. A first feeding mechanism 533 is provided on one side of the first sliding mechanism 532. The first feeding mechanism 533 includes a loading seat 581 and a feeding drive source 582 for conveying the sand-proof seat 244 to the loading seat 581. Specifically... Figure 11As shown, the first frame 531 includes a second base 561, on which a plurality of vertically arranged first support rods 562 are provided. A first top plate 563 is provided at the top of the first support rods 562, and the first sliding mechanism 532 is provided on the first top plate 563. The first sliding mechanism 532 in this patent includes a sliding guide rail 551 disposed on the first top plate 563, and a sliding slider 552 disposed on the sliding guide rail 551. The first linear drive member 571 is connected to the sliding slider 552 and is driven to move by the sliding slider 552. In this embodiment, the first linear drive 571 is a cylinder fixed on the sliding slider 552. A material picker 572 is driven at the end of the first linear drive 571. A second linear drive 573 is provided on the material picker 572. The second linear drive 573 can also be a cylinder. A material picker pin 574 passing through the material picker 572 is driven by the second linear drive 573. The material picker sleeve 575 is located below the material picker 572, and the material picker pin 574 is located in the material picker sleeve 575 to pick up materials.

[0098] The loading seat 581 in the first feeding mechanism 533 is located on the base of the first frame 531. The feeding drive source 582 is a vibratory feeder connected to the loading seat 581. The vibratory feeder vibrates the sand-proof seats 244 one by one into the loading seat 581. During operation, the conveying assembly 2 delivers the deep well pump body 24 to the first assembly station 53. Then, the first sliding mechanism 532 moves to make the picking pin 574 on the first sliding mechanism 532 face the loading seat 581. Then, the first linear drive member 571 works to grab the sand-proof seats 244 on the loading seat 581. The sand-proof seat 244 has a through hole in the center. When the first linear drive 571 operates downward, it will drive the picking pin 574 and the picking sleeve 575 located on the picking frame 572 to move downward. At this time, the second linear drive 573 will drive the picking pin 574 to move and extend out of the picking sleeve 575 and insert into the through hole of the sand-proof seat 244. The sand-proof seat 244 is fixed in the picking pin 574 by interference fit and abuts against one end of the picking sleeve 575. Then, the first linear drive 571 and the second linear drive 573 rise and reset sequentially, and the first feeding mechanism 533 operates again to position the material-taking pin 574, which is fixed with the sand-proof seat 244, above the deep well pump body 24. The upper end of the deep well pump body 24 is provided with a rotor 247, and the sand-proof seat 244 is used to mount on the rotor 247. At this time, the first linear drive 571 operates to lower the sand-proof seat 244 above the rotor 247 of the deep well pump body 24, and to position the material-taking pin 574 above the sand-proof seat 244. The end of the material pin 574 abuts against the rotor 247, and then the first linear drive 571 continues to work and move downward, while the material picking pin 574 retracts under the action of the second linear drive 573. The material picking sleeve 575 presses down on the sand-proof seat 244 to press the sand-proof seat 244 onto the rotor 247 to achieve fixation. The inner diameter of the material picking sleeve 575 is slightly larger than that of the rotor 247, so it can be fitted outside the rotor 247 and can press the sand-proof seat 244 onto it.

[0099] like Figure 10 As shown, the second assembly station 54 includes a second frame 541, a second sliding mechanism 542, and a second feeding mechanism 545. The second frame 541 is disposed on one side of the tooling 21 and includes a second base 561 horizontally positioned below the conveying assembly 2. Both ends of the second base 561 extend to both sides of the conveying assembly 2. Vertically arranged first support rods 562 are provided on both ends of the second base 561. The top of the first support rods 562 is connected to a first top plate 563 through a plug-in structure or fasteners. The second sliding mechanism 542 is fixed on the first top plate 563.

[0100] like Figure 10 As shown, similar to the first sliding mechanism 532, the second sliding mechanism 542 includes a sliding guide rail 551 fixed on the first top plate 563 and a sliding slider 552 sliding along the sliding guide rail 551. The first material-collecting component 543 and the second material-collecting component 544 are fixed on the sliding slider 552 and are vertically downward, to grab the sand-proof pad 245 and the sand-proof cap 246 and install them onto the deep well pump body 24. In this patent, the first top plate 563 has an opening, the sliding guide rail 551 is arranged on both sides of the opening, and the first material-collecting component 543 and the second material-collecting component 544 pass through the opening to collect material downward.

[0101] In this patent, the first material-receiving component 543 and the second material-receiving component 544 are mounted on the same sliding block 552. During installation, the second material-receiving component 544 first picks up the sand-proof pad 245 and places it onto the deep well pump body 24, and then the first material-receiving component 543 picks up the sand-proof cap 246 and presses it onto the sand-proof pad 245, thus assembling the sand-proof structure in this patent. The structure of the sand-proof cap 246 is similar to that of the sand-proof seat 244, with a through hole in its center. Therefore, the first material-receiving component 543 in this patent is similar to the structure at the first assembly station 53, and it also includes a first linear drive component 571, a second linear drive component 573, and a material-receiving sleeve 575 for fixing on the sliding block 552. A second feeding mechanism 545 is provided on one side of the first material handling component 543, mounted on the second frame 541. Two second feeding mechanisms 545 are provided, located on opposite sides of the tooling 21. The two feeding mechanisms 545 are used to convey the sandproof pad 245 and the sandproof cap 246, respectively. Each feeding mechanism includes a loading seat 581 and a feeding drive source 582 connected to one side of the loading seat 581. In this embodiment, the feeding drive source 582 is a vibratory feeder. The vibratory feeder continuously vibrates to feed the sandproof pad 245 and the sandproof cap 246 to the two loading seats 581. The second material handling component 544 includes a third linear drive member 5441, which is a cylinder fixed to the sliding slider 552. The third linear drive member 5441 drives a chuck 5442, which can clamp the two ends of the sandproof pad 245 to achieve the gripping and transport of the sandproof pad 245.

[0102] During operation, the second sliding mechanism 542 first positions the second material-grabbing component 544 on the second feeding mechanism 545, which holds the sand-proof pad 245, to grab the sand-proof pad 245. Then, the second sliding mechanism 542 moves to make the second material-grabbing component 544 face the rotor 247 on the deep well pump body 24. Then, the third linear drive 5441 drives the claw 5442 to descend and put the sand-proof pad 245 onto the rotor 247. Then, the first material-grabbing component 543 is positioned on the second feeding mechanism 545, where the sand cap 246 is placed, by the second sliding mechanism 542 to grab the sand cap 246. Similar to the structure of the first assembly station 53, the first material-grabbing component 543 is positioned opposite the rotor 247 on the deep well pump body 24 by the second sliding mechanism 542. The sand cap 246 is fixed on the rotor 247 of the deep well pump body 24 by the cooperation of the material-grabbing pin 574 and the material-grabbing sleeve 575, thus realizing the installation.

[0103] In summary, this patent achieves automatic installation of the sand-proof components by sequentially setting up a first assembly station 53 and a second assembly station 54 in conjunction with the conveying component 2, significantly increasing product manufacturing efficiency. In particular, at the second assembly station 54, the first material-picking component 543 and the second material-picking component 544 are sequentially driven by the second sliding mechanism 542 to the second feeding mechanism 545 and tooling 21, thereby achieving the sequential installation of the sand-proof pad 245 and the sand-proof cap 246. By placing both the first material-picking component 543 and the second material-picking component 544 on the second sliding mechanism 542, the number of stations can be effectively reduced, the overall size of the assembly device can be simplified, and the product assembly speed can be accelerated.

[0104] In fact, a skeleton oil seal assembly device 7 is also provided between the sand-proof structure assembly device and the upper end cover 241 fastening device. It is used to install the skeleton oil seal 71 on the rotor 247 of the deep well pump body 24 before installing the sand-proof structure. The skeleton oil seal assembly device 7 has a structure that is basically the same as the first assembly station 53. It uses a sliding structure to drive the first linear drive member 571 and the second linear drive member 573 to grip the skeleton oil seal 71 for press-fitting.

[0105] The oil injection device is located on the rear side of the sand-proof structure assembly device and in the oil injection area 14. It includes an assembly bracket 63, an oil injection gun 64, and a sealing component 65. The assembly bracket 63 is located on one side of the delivery component 2. The oil injection gun 64 is slidably mounted on the assembly bracket 63 and can slide to the deep well pump body 24 located in the delivery component 2 to inject oil into the deep well pump body 24. The sealing component 65 is also slidably mounted on the assembly bracket 63 and is used to slide onto the deep well pump body 24 to seal the oil injection port on the deep well pump body 24.

[0106] like Figure 13 As shown in this patent, the assembly bracket 63 includes a third base 631, a plurality of second support rods 632, and a second top plate 633. The third base 631 is positioned horizontally below the conveying assembly 2, with both ends extending to the sides of the conveying assembly 2. The second support rods 632 are respectively disposed on both ends of the third base 631, extending vertically upward. The second top plate 633 is connected between the tops of the plurality of second support rods 632 and is located above the conveying assembly 2. The oil injection gun 64 and the sealing assembly 65 are slidably mounted on the second top plate 633. The horizontally positioned third base 631 allows the second top plate 633 to be positioned horizontally above the conveying assembly 2, facilitating the operation of the oil injection gun 64 and the sealing assembly 65 mounted on the horizontal plate.

[0107] like Figure 14 As shown, the second top plate 633 is provided with an oil injection slide rail 6331, and an oil injection slide plate 6332 is slidably mounted on the oil injection slide rail 6331. The oil injection gun 64 and the sealing assembly 65 are fixed on the oil injection slide plate 6332. The second top plate 633 is also provided with a first opening 6333 in the middle for the oil injection gun 64 and the sealing assembly 65 to pass through. The oil injection gun 64 and the sealing assembly 65 pass through the first opening 6333 and descend to face the deep well pump body 24 located on the delivery assembly 2. The first opening 6333 facilitates the operation of the oil injection gun 64 and the sealing assembly 65.

[0108] like Figure 14-16 As shown, a fourth linear drive component 641 is fixed on the oil injection slide plate 6332. The fourth linear drive component 641 drives a first drive plate 642, and the oil injection gun 64 is fixed on the first drive plate 642. The fourth linear drive component 641 is a cylinder fixed on the oil injection slide plate 6332. The extended end of the cylinder is connected to the first drive plate 642. Both ends of the first drive plate 642 are also provided with motion guide rods 634 that pass through the oil injection slide plate 6332. The motion guide rods 634 are used to increase the stability of the movement of the fourth linear drive component 641. The first drive plate 642 is used to provide installation space for the oil injection gun 64. The oil injection gun 64 is used to connect to the external oil circuit. During operation, the oil injection gun 64 is inserted into the oil injection port located on the deep well pump body 24 under the drive of the oil injection slide plate 6332 and the fourth linear drive component 641 to inject oil.

[0109] like Figure 16As shown, a fifth linear drive component 651 is fixed on the oil filling slide plate 6332, and the fifth linear drive component 651 drives the second drive plate 652. The fifth linear drive component 651 is also a cylinder mounted on the oil filling slide plate 6332, similar to the fourth linear drive component 641. The extended end of the cylinder is connected to the second drive plate 652, and both ends of the second drive plate 652 are provided with motion guide rods 634 passing through the oil filling slide plate 6332. The sealing assembly 65 includes a sealing motor 653 mounted on the second drive plate 652 and a bit 654 driven by the sealing motor 653. A feed head 655 for feeding material to the bit 654 is provided on one side of the bit 654. The sealing motor 653 is specifically a servo sealing motor 653, which has a certain volume. To facilitate the installation of the servo sealing motor 653, a second opening 6334 is provided on the oil filling slide plate 6332 located on one side of the second drive plate 652. The sealing motor 653 is located within the second opening 6334. A fixing plate 656 is provided on the lower end of the sealing motor 653, and the fixing plate 656 is connected to the second drive plate 652. During operation, the fifth linear drive member 651 drives the second drive plate 652 to move up and down, which in turn drives the fixing plate 656 to move up and down. Finally, the fixing plate 656 drives the sealing motor 653 to move within the second opening 6334. The second opening 6334 provides installation space for the sealing motor 653, facilitating its installation and improving the accuracy of the electric screwdriver operation.

[0110] Furthermore, the sealed motor 653 is also provided with an extension bracket 6531, such as... Figure 16 As shown, the extension frame 6531 is mounted on the fixed plate 656. The extension frame 6531 is generally L-shaped. A guide tube 6532 is located at the bottom of the extension frame 6531, positioned along the movement path of the screwdriver bit 654. Below the guide tube 6532 is a feed head 655 for feeding the screwdriver bit 654. A feed inlet 6551 is located on one side of the feed head 655, and a pipe fitting is connected to the feed inlet 6551 for connecting to an external feeding structure. The screwdriver bit 654, under the action of the servo sealing motor 653, passes through the extension frame 6531 and the guide tube 6532, and is located in the feed head 655. The external feeding structure feeds fasteners into the feed head 655 through the feed inlet 6551, causing the electric screwdriver to abut against the fasteners in the feed head 655. The entire sealing assembly 65 can be positioned above the oil injection port of the deep well pump body 24 under the action of the oil injection slide plate 6332. Under the drive of the fifth linear drive member 651 and the sealing motor 653, the fastener is fixed in the oil injection port to achieve the sealing of the oil injection port.

[0111] In summary, this patent achieves oil injection and automatic sealing of the deep well pump body 24 through the oil injection gun 64 and sealing assembly 65, realizing automated manufacturing and increasing product manufacturing efficiency. Furthermore, by placing the oil injection gun 64 and sealing assembly 65 on the same oil injection slide plate 6332, the oil injection gun 64 and sealing assembly 65 are transported using only one slide plate 6332, simplifying the transport structure and facilitating the manufacturing of the assembly device in this patent.

[0112] In other embodiments, the cylinders in the above-mentioned production line can also be linear motor push rods, as long as they can achieve linear push.
