Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, specifically a pump core assembly machine. Background Technology

[0002] As the core component of pump equipment, the pump core directly determines the pump's performance, efficiency, and reliability, and is widely used in industrial manufacturing, civil water supply, aerospace, and new energy fields. Modern pump cores utilize high-strength, corrosion-resistant composite materials, such as ceramic alloys, titanium alloys, and engineering plastics, significantly extending their service life. The pump core structure in a spring-loaded pump mainly consists of the pump body, sealing beads, spring, and piston assembly, which require assembly using a pump core assembly machine during production.

[0003] For example, a pump head assembly machine for a press pump, disclosed in CN215942069U, includes an assembly frame, an assembly turntable rotatably mounted on the assembly frame, and a first drive motor driving the assembly turntable to rotate. Around the assembly turntable are arranged a pump core feeding plate, a glass bead feeding plate, and a spring feeding plate for vibrating and feeding materials to the assembly turntable. Grooves for vertically accommodating pump cores are equidistantly arranged along the edge of the assembly turntable. A notched limiting ring is fixedly mounted on the assembly frame around the assembly turntable. The outlet of the pump core feeding plate is connected to a feeding track that feeds the pump core from one end of the notch in the limiting ring into the groove on the assembly turntable. The assembly turntable drives the pump core to sequentially rotate within the limiting ring to the dropping positions of the glass bead feeding plate and the spring feeding plate, completing the assembly of the glass beads and springs, and then discharging from the other end of the notch in the limiting ring.

[0004] However, the aforementioned assembly machine has difficulty in assembling multiple components within the pump body simultaneously, resulting in low assembly efficiency. Furthermore, it cannot automatically detect the assembly position of the components within the pump body in real time, which affects the assembly quality. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-4 and Figure 6The pump core assembly machine of this embodiment includes a frame 1. A first turntable conveying mechanism 2 and a second turntable conveying mechanism 3 are rotatably connected to the top two sides of the frame 1, respectively, for rotating and conveying the components to be assembled. A pump body feeding mechanism 4 and an inner spring feeding frame 9 are respectively arranged on the outer side of the first turntable conveying mechanism 2. The pump body feeding mechanism 4 is used to feed and convey the pump body. A pair of inner spring feeding mechanisms 10 are symmetrically arranged on the top of the inner spring feeding frame 9 for feeding and conveying the inner springs. A first conveying track 11 is provided between the pump body feeding mechanism 4 and the first turntable conveying mechanism 2, for conveying the material output from the pump body feeding mechanism 4 to the first turntable. The conveying mechanism 2, specifically the first turntable conveying mechanism 2, has a sealing bead pressing mechanism 24, a sealing bead detection mechanism 25, an inner spring pressing mechanism 26, and an inner spring detection mechanism 27 sequentially arranged around its rotational direction along its axis. The sealing bead pressing mechanism 24 presses the sealing beads into the pump body; the sealing bead detection mechanism 25 detects the pressing state of the sealing beads; the inner spring pressing mechanism 26 presses the inner spring; and the inner spring detection mechanism 27 detects the assembly state of the inner spring. A second conveying track 12 is provided between the first turntable conveying mechanism 2 and the second turntable conveying mechanism 3 to transport the pump body after the sealing beads and inner spring are assembled. The second turntable conveying mechanism 3 has a support frame 15 fixedly connected to the outer side of the first turntable conveying mechanism 2. A lifting plate 22 is slidably connected between the inner sidewalls of the support frame 15. The sealing bead pressing mechanism 24 includes a first mounting base 2401, which is fixedly connected to the outer sidewall edge of the lifting plate 22. Several first pressing cylinders 2402 are evenly and vertically arranged around the axis of the first turntable conveying mechanism 2 on the top outer side of the first mounting base 2401. The piston rod of the first pressing cylinder 2402 is fixedly connected to a first pressing rod 2407. A first inlet is arranged parallel to the first pressing cylinder 2402 on the side facing the axis of the first turntable conveying mechanism 2. The top of the frame 1 is fixedly connected to the material pipe 2403 and the fixed frame 7. The top of the fixed frame 7 is fixedly connected to the sealing bead feeding mechanism 8. Several first feed pipes 2403 are connected to the sealing bead feeding mechanism 8. The bottom outer side of the first pressing cylinder 2402 is horizontally provided with a first feeding cylinder 2405. The piston rod of the first feeding cylinder 2405 is fixedly connected to a first feeding push block 2406. The top of the first feeding push block 2406 is provided with a first feeding hole 2408. Several first guide joints 2404 are vertically fixedly connected to the bottom of the first mounting base 2401. The opposing first guide joints 2404 are coaxially arranged with the first pressure rod 2407.During pump core assembly, the pump body is conveyed along the first conveying track 11 to the conveying groove on the edge of the first turntable conveying mechanism 2 via the pump body feeding mechanism 4. During the conveying process, the first turntable conveying mechanism 2 rotates synchronously, driving the pump body to rotate accordingly. When the pump body moves to the bottom of the corresponding first guide joint 2404, the first turntable conveying mechanism 2 stops rotating. At this time, the sealing bead feeding mechanism 8 conveys the sealing beads to the corresponding first feed pipe 2403, causing the sealing beads to fall into the first feed hole 2408 on the top of the first feed pusher 2406. Then, the first feed cylinder 2402 drives the first feed pusher 2406 to move towards the first feed hole 2408 on the top of the first feed pusher 2406. The first guide joint 2404 moves in the direction until the first feeding hole 2408 is directly below the first pressure rod 2407 and stops. At this time, the lifting plate 22 moves downward, causing the first guide joint 2404 to move downward to insert into the pump body. Then, the first pressure rod 2407 is driven downward by the first pressing cylinder 2402 to penetrate the first feeding hole 2408, pushing the sealing bead inside the first feeding hole 2408 along the first guide joint 2404 into the pump body to press the sealing bead. Through the above steps, the synchronous pressing of multiple sets of pump body sealing beads can be achieved, effectively improving the pressing efficiency.

[0037] Please see Figure 7 A first drive motor 16 is fixedly connected to the bottom inner side of the frame 1. A transmission shaft 17 is rotatably connected between the inner sidewalls of the frame 1. The shaft of the first drive motor 16 is connected to the end of the transmission shaft 17 via a synchronous belt mechanism. A first transmission wheel 18 and a second transmission wheel 19 are fixedly connected to the middle part of the transmission shaft 17. A first transmission groove 45 is opened on the sidewall of the first transmission wheel 18. A first lifting shaft 20 is vertically connected to the axis of the lifting plate 22. The bottom end of the first lifting shaft 20 is rotatably connected to the first transmission groove 45 via a roller. A second transmission groove 46 is opened on the sidewall of the second transmission wheel 19. When the first turntable conveying mechanism 2 rotates, the first drive motor 16 drives the transmission shaft 17 to rotate via the synchronous belt mechanism, causing the first transmission wheel 18 and the second transmission wheel 19 to rotate accordingly. When the first transmission wheel 18 rotates, it drives the first lifting shaft 20, which is slidably connected to it, to move in the vertical direction through the first transmission groove 45 on its sidewall, thereby driving the lifting plate 22 to move accordingly.

[0038] The sealing bead detection mechanism 25 includes several upper conduits 2501 and lower conduits 2502 arranged in opposite directions. The upper conduits 2501 are fixedly connected to the edge of the lifting plate 22. The bottom of the lower conduits 2502 are fixedly connected to a movable seat 23. The bottom of the movable seat 23 is vertically fixedly connected to a second lifting shaft 21. The bottom end of the second lifting shaft 21 is rotatably connected to the second transmission groove 46 through a roller. The bottom of the upper conduits 2501 is slidably connected to an upper sealing joint 2504. The top of the lower conduits 2502 is slidably connected to a lower sealing joint 2505. A first return spring 2503 is connected between the upper sealing joint 2504 and the upper conduit 2501, and between the lower sealing joint 2505 and the lower conduit 2502. The bottom of the lower conduit 2502 is connected to a pressure gauge. When the second transmission wheel 19 rotates, it drives the second lifting shaft 21 to rotate vertically through the second transmission groove 46 on its side wall, thereby causing the movable seat 23 to move accordingly. When the pump body moves to the corresponding upper guide tube 2501 and lower guide tube 2502 after the sealing beads are pressed in, the pump body stops moving. At this time, the lifting plate 22 and the movable seat 23 move synchronously towards each other under the drive of the first transmission groove 45 and the second transmission groove 46, so that the upper guide tube 2501 and the lower guide tube 2502 move towards each other until the upper sealing joint 2504 and the lower sealing joint 2505 abut against the top and bottom of the pump body, respectively. At this time, gas is introduced into the interior of the upper guide tube 2501. If the pressure gauge at the bottom of the lower guide tube 2502 detects a change in pressure, the sealing beads inside the pump body are not assembled in place; otherwise, the sealing beads inside the pump body are assembled in place. Through the above steps, the synchronous real-time detection of the sealing bead assembly status can be achieved, effectively improving the assembly quality of the product.

[0039] Please see Figure 8The inner spring pressing mechanism 26 includes a second mounting base 2601, which is fixedly connected to the outer side wall edge of the lifting plate 22. Several second pressing cylinders 2602 are evenly and vertically arranged around the axis of the first turntable conveying mechanism 2 on the top outer side of the second mounting base 2601. A second pressing rod 2604 is fixedly connected to the piston rod of each second pressing cylinder 2602. A second feed pipe 2603 is arranged parallel to the side of the second pressing cylinder 2602 facing the axis of the first turntable conveying mechanism 2. The second feed pipe 2603 is connected to the inner spring feeding mechanism 10. The second feeding cylinder 2605 is horizontally arranged on the outer side of the bottom of the second pressing cylinder 2602. The piston rod of the second feeding cylinder 2605 is fixedly connected to the second feeding push block 2606. The top of the second feeding push block 2606 is provided with a second feeding hole 2607. The bottom of the second mounting base 2601 is vertically fixedly connected to a number of second guide joints 2608. The opposing second guide joints 2608 are coaxially arranged with the second pressure rod 2604. After the sealing bead test is completed, the pump body moves with the first turntable conveying mechanism 2 to the bottom of the corresponding second guide joint 2608. At this time, the first turntable conveying mechanism 2 stops moving. The inner spring feeding mechanism 10 delivers the inner spring to the corresponding second feed pipe 2603, so that the inner spring falls into the second feeding hole 2607 at the top of the second feeding push block 2606. Then, the second feeding cylinder 2605 drives the second feeding push block 2606 to move towards the second guide joint 2608 until the second feeding hole 2607 is located at the bottom of the second guide joint 2608. The second pressure rod 2604 stops directly below the second pressure rod 2604. At this time, the lifting plate 22 moves downward, causing the second guide joint 2608 to move downward to be inserted into the pump body. Then, the second pressure rod 2604 is driven downward by the second pressure cylinder 2602 to pass through the second feeding hole 2607, pushing the inner spring inside the second feeding hole 2607 along the second guide joint 2608 into the pump body for pressure fitting. Through the above steps, the synchronous pressure fitting of multiple sets of pump body springs can be achieved, effectively improving the pressure fitting efficiency.

[0040] Please see Figure 9The inner spring detection mechanism 27 includes several movable push rods 2701, which are vertically slidably connected to the top edge of the lifting plate 22. A second return spring 2702 is connected between the bottom end of the movable push rod 2701 and the top of the lifting plate 22. A proximity switch 2703 is provided on the top of the movable push rod 2701. After the inner spring is pressed in, the pump body moves with the first turntable conveying mechanism 2 to the bottom of the corresponding movable push rod 2701, causing the first turntable conveying mechanism 2 to stop moving. At this time, the lifting plate 22 moves downward, causing the bottom end of the movable push rod 2701 to insert into the pump body. If the movable push rod 2701 moves upward due to the upward elastic force of the inner spring in the pump body, causing the proximity switch 2703 on the top of the movable push rod 2701 to receive a signal and start illuminating, then the inner spring in the pump body is assembled in place; otherwise, the inner spring in the pump body is not assembled in place. Through the above steps, the synchronous real-time detection of the inner spring assembly status can be achieved, further improving the assembly quality of the product.

[0041] A plurality of first feeding cylinders 30 are horizontally arranged around the first turntable conveying mechanism 2 on the side of the inner spring detection mechanism 27 away from the inner spring pressing mechanism 26. The piston rod of the first feeding cylinder 30 is fixedly connected to a first limiting block 31. A first feeding port 29 is provided on the lower side of the plurality of first limiting blocks 31. A first receiving box 28 is detachably provided at the bottom of the first feeding port 29. When the inner spring detection is completed, the pump body moves with the first turntable conveying mechanism 2 to the inner side of the corresponding first limiting block 31. At this time, the first feeding cylinder 30 corresponding to the position of the defective product drives the first limiting block 31 to retract until it is detached from the defective product, so that the defective product falls into the interior of the first receiving box 28 at the bottom along the first feeding port 29, thereby realizing the automatic screening of defective products and preventing them from being mixed with qualified products.

[0042] Please see Figure 10The second turntable conveying mechanism 3 is provided with a cap feeding mechanism 5 and a piston feeding mechanism 6 on its outer side. A third feeding track 13 is provided between the cap feeding mechanism 5 and the second turntable conveying mechanism 3. A fourth feeding track 14 is provided between the piston feeding mechanism 6 and the second turntable conveying mechanism 3. The second turntable conveying mechanism 3 includes a turntable. A second drive motor 32 is provided on the lower side of the axis of the turntable. Several lower feeding grooves 38 are opened around the axis of the turntable on the lower side of the edge of the turntable. An upper movable block 40 is provided on the top of each lower feeding groove 38. The upper movable block 40 is slidably connected to the turntable along the axis of the turntable. An upper feeding groove 37 is opened on the outer wall of the upper movable block 40. A telescopic cylinder is connected to the inner side of the upper movable block 40. A contour limiting plate 39 is provided on the outer side of the edge of the turntable. After screening, the pump body detaches from the first rotary conveyor mechanism 2 and moves along the second conveyor track 12 to the interior of the lower conveyor trough 38 on the edge of the second rotary conveyor mechanism 3. At this time, the second drive motor 32 drives the rotary disk to start rotating, causing the pump body to rotate accordingly. During the rotation of the pump body with the rotary disk, the cap feeding mechanism 5 delivers the cap to the connection between the third conveyor track 13 and the second rotary conveyor mechanism 3, and the piston feeding mechanism 6 delivers the piston assembly to the connection between the fourth conveyor track 14 and the second rotary conveyor mechanism 3. When the pump body rotates with the rotary disk and passes through the third conveyor track 13, the cap in the third conveyor track 13 enters the top of the corresponding upper conveyor trough 37 and moves synchronously with the pump body. Similarly, when the pump body passes through the fourth conveyor track 14, the piston assembly in the fourth conveyor track 14 enters the middle of the corresponding upper conveyor trough 37 and moves with the pump body and the cap. During movement, the contour limiting plate 39 can limit the movement of each component.

[0043] Please see Figures 11-14A connecting frame is provided on the outer side of the rotating disk. A contour plate 43 is fixedly connected to the top edge of the connecting frame around the axis of the rotating disk. A rotating ring is fixedly connected to the top of the rotating disk. The rotating ring is rotatably connected to the connecting frame. Several lifting rods 41 are vertically and slidably connected to the top edge of the rotating ring around the axis of the rotating disk. The lifting rods 41 are slidably connected to the middle of the connecting frame. A guide wheel 44 is rotatably connected to the top of the lifting rod 41. The guide wheel 44 is slidably connected to the contour plate 43. A pressure head 42 is fixedly connected to the bottom of the lifting rod 41. During the rotation of the rotating disc, the rotating ring and the lifting rod 41 rotate accordingly. As the lifting rod 41 rotates, its top guide wheel 44 moves around the contour plate 43, causing the lifting rod 41 to move vertically along the contour of the contour plate 43. When the corresponding pump body, end cap, and piston assembly are all in the ready-to-install state, the lifting rod 41 moves downwards under the action of the contour plate 43, causing the pressure head 42 at the bottom of the lifting rod 41 to move downwards until it passes through the end cap, and then presses the piston assembly down. The piston assembly is installed inside the pump body; at this time, the end cap is fitted onto the outside of the pressure head 42, and the end cap is limited by the protruding edge at the top of the upper conveying trough 37; after the piston assembly is pressed in, the telescopic cylinder at the corresponding position edge of the rotating disk drives the upper movable block 40 to move away from the pressure head 42, so that the end cap is disengaged from the upper conveying trough 37. At this time, the pressure head 42 continues to move downward, pressing the end cap fitted onto the top of the pump body; through the above steps, the orderly automatic pressing of the piston assembly and the end cap can be achieved, avoiding misalignment of the piston assembly and the end cap during pressing.

[0044] Please see Figure 5 A second feeding cylinder 33 is horizontally arranged on the side of the fourth feeding track 14 away from the third feeding track 13. The piston rod of the second feeding cylinder 33 is fixedly connected to a second limiting block 34. A second receiving box 35 is detachably arranged at the bottom of the second limiting block 34. A discharge track 36 is arranged on the side of the second feeding cylinder 33 away from the fourth feeding track 14. After pressing, the assembled pump body moves to the inside of the second limiting block 34 with the rotating disk. When a defective product passes through the limiting block 34, the second feeding cylinder 33 drives the second limiting block 34 to disengage from the defective product, causing the defective product to fall into the second receiving box 35 at the bottom. Normal products are discharged along the discharge track 36 after passing through the second limiting block 34, thereby realizing the secondary screening of defective products.

[0045] Working principle: During pump core assembly, the pump body is conveyed along the first conveying track 11 to the conveying groove on the edge of the first turntable conveying mechanism 2 via the pump body feeding mechanism 4. During the conveying process, the first turntable conveying mechanism 2 rotates synchronously, driving the pump body to rotate accordingly. When the pump body moves to the bottom of the corresponding first guide joint 2404, the first turntable conveying mechanism 2 stops rotating. At this time, the sealing bead feeding mechanism 8 conveys the sealing bead to the corresponding first feed pipe 2403, causing the sealing bead to fall into the first feed hole 2408 on the top of the first feed pusher 2406. Then, the first feed cylinder 2402 drives the first feed pusher 2406. 6 moves towards the first guide joint 2404 until the first feeding hole 2408 is directly below the first pressure rod 2407 and stops; at this time, the lifting plate 22 moves downward, causing the first guide joint 2404 to move downward to be inserted into the pump body, and then the first pressure rod 2407 is driven downward by the first pressure cylinder 2402 to penetrate the first feeding hole 2408, pushing the sealing bead inside the first feeding hole 2408 along the first guide joint 2404 into the pump body to press the sealing bead; through the above steps, the synchronous pressing of multiple sets of pump body sealing beads can be realized, effectively improving the pressing efficiency.

[0046] When the second transmission wheel 19 rotates, it drives the second lifting shaft 21 to rotate vertically through the second transmission groove 46 on its side wall, thereby causing the movable seat 23 to move accordingly. When the pump body moves to the corresponding upper guide tube 2501 and lower guide tube 2502 after the sealing beads are pressed in, the pump body stops moving. At this time, the lifting plate 22 and the movable seat 23 move synchronously towards each other under the drive of the first transmission groove 45 and the second transmission groove 46, so that the upper guide tube 2501 and the lower guide tube 2502 move towards each other until the upper sealing joint 2504 and the lower sealing joint 2505 abut against the top and bottom of the pump body, respectively. At this time, gas is introduced into the interior of the upper guide tube 2501. If the pressure gauge at the bottom of the lower guide tube 2502 detects a change in pressure, the sealing beads inside the pump body are not assembled in place; otherwise, the sealing beads inside the pump body are assembled in place. Through the above steps, the synchronous real-time detection of the sealing bead assembly status can be achieved, effectively improving the assembly quality of the product.

[0047] After the sealing bead test is completed, the pump body moves with the first turntable conveying mechanism 2 to the bottom of the corresponding second guide joint 2608. At this time, the first turntable conveying mechanism 2 stops moving. The inner spring feeding mechanism 10 delivers the inner spring to the corresponding second feed pipe 2603, so that the inner spring falls into the second feeding hole 2607 at the top of the second feeding push block 2606. Then, the second feeding cylinder 2605 drives the second feeding push block 2606 to move towards the second guide joint 2608 until the second feeding hole 2607 is located at the bottom of the second guide joint 2608. The second pressure rod 2604 stops directly below the second pressure rod 2604. At this time, the lifting plate 22 moves downward, causing the second guide joint 2608 to move downward to be inserted into the pump body. Then, the second pressure rod 2604 is driven downward by the second pressure cylinder 2602 to pass through the second feeding hole 2607, pushing the inner spring inside the second feeding hole 2607 along the second guide joint 2608 into the pump body for pressure fitting. Through the above steps, the synchronous pressure fitting of multiple sets of pump body springs can be achieved, effectively improving the pressure fitting efficiency.

[0048] After the inner spring is installed, the pump body moves with the first turntable conveying mechanism 2 to the bottom of the corresponding movable push rod 2701, causing the first turntable conveying mechanism 2 to stop moving. At this time, the lifting plate 22 moves downward, causing the bottom end of the movable push rod 2701 to insert into the pump body. If the movable push rod 2701 moves upward due to the upward elastic force of the inner spring in the pump body, causing the proximity switch 2703 at the top of the movable push rod 2701 to receive a signal and start illuminating, then the inner spring in the pump body is assembled in place; otherwise, the inner spring in the pump body is not assembled in place. Through the above steps, the synchronous real-time detection of the inner spring assembly status can be achieved, further improving the assembly quality of the product. After the inner spring is detected, the pump body moves with the first turntable conveying mechanism 2 to the inside of the corresponding first limit block 31. At this time, the first discharge cylinder 30 corresponding to the defective product position drives the first limit block 31 to retract and detach from the defective product, causing the defective product to fall into the bottom of the first receiving box 28 along the first discharge port 29, thereby realizing the automatic screening of defective products and preventing them from being mixed with qualified products.

[0049] After screening, the pump body detaches from the first rotary conveyor mechanism 2 and moves along the second conveyor track 12 to the lower conveyor trough 38 at the edge of the second rotary conveyor mechanism 3. At this time, the second drive motor 32 drives the rotary disk to start rotating, causing the pump body to rotate accordingly. During the rotation of the pump body with the rotary disk, the cap feeding mechanism 5 delivers the cap to the connection between the third conveyor track 13 and the second rotary conveyor mechanism 3, and the piston feeding mechanism 6 delivers the piston assembly to the connection between the fourth conveyor track 14 and the second rotary conveyor mechanism 3. When the pump body rotates with the rotary disk past the third conveyor track 13, the cap in the third conveyor track 13 enters the top of the corresponding upper conveyor trough 37 and moves synchronously with the pump body. Similarly, when the pump body passes the fourth conveyor track 14, the piston assembly in the fourth conveyor track 14 enters the middle of the corresponding upper conveyor trough 37 and moves with the pump body and the cap. During the movement, the contour limiting plate 39 can limit the movement of each component. During the rotation of the rotary disk, the rotating ring and the lifting rod 41 rotate accordingly. During the rotation of the lifting rod 41, the guide wheel 44 at its top moves around the contour plate 43, causing the lifting rod 41 to move vertically along the contour of the contour plate 43. When the corresponding pump body, end cap, and piston assembly are all in the ready-to-install state, the lifting rod 41 moves downward under the action of the contour plate 43, causing the pressure head 42 at the bottom of the lifting rod 41 to move downward until it passes through the end cap, and then presses the piston assembly into the pump body. At this time, the end cap is sleeved on the outside of the pressure head 42, and the end cap is limited by the protruding edge at the top of the upper conveying trough 37. After the piston assembly is pressed, the telescopic cylinder at the corresponding position edge of the rotating disk drives the upper movable block 40 to move away from the pressure head 42, causing the end cap to disengage from the upper conveying trough 37. At this time, the pressure head 42 continues to move downward, pressing the end cap sleeved on its outside onto the top of the pump body. Through the above steps, the orderly and automatic pressing of the piston assembly and end cap can be achieved, avoiding misalignment of the piston assembly and end cap during pressing.

[0050] After pressing is completed, the assembled pump body moves with the rotating disc to the inside of the second limiting block 34. When the defective product passes the limiting block 34, the second feeding cylinder 33 drives the second limiting block 34 to disengage from the defective product, so that the defective product falls into the second receiving box 35 at the bottom. Normal products are discharged along the discharge track 36 after passing the second limiting block 34, thereby realizing the secondary screening of defective products.
