Description

A high-lift impeller machining device for industrial pumps Technical Field

[0001] This application relates to the field of centrifugal pump processing technology, and in particular to a high-lift impeller processing device for industrial pumps. Background Technology

[0002] Currently, the shape and size of the pump impeller are closely related to the pump's performance. The impeller is the core component of the pump and a major factor affecting its working efficiency. The shape and arrangement of the blades in the impeller have a significant impact on the impeller's head.

[0003] In existing technologies, centrifugal pumps of the same model use a uniform impeller design, maintaining consistent structural dimensions and performance parameters to ensure a fixed flow rate and head output under standard operating conditions. This standardized design facilitates mass production and maintenance, and meets the basic requirements for pump performance stability in conventional industrial applications.

[0004] Regarding the aforementioned technologies, centrifugal pumps often require increased head during operation. However, changing the impeller specifications can lead to increased costs, and the replaced impeller may not be usable under specific operating conditions. Therefore, there is an urgent need for an impeller processing device that can increase the impeller head without changing the impeller specifications. Summary of the Invention

[0005] To increase the impeller head, this application provides a high-head impeller machining device for industrial pumps.

[0006] This application provides a high-lift impeller machining device for industrial pumps, which adopts the following technical solution:

[0007] A high-lift impeller processing device for industrial pumps includes a support and a welding torch. The welding torch is used to weld the impeller on the support. A placement groove is provided at the upper end of the support. A movable component is provided on one side of the upper end of the support along the length direction for conveying the impeller into the placement groove. A limiting component is provided on one side of the support along the width direction for fixing the position of the impeller. A first motor is fixed at the lower end of the support. The output shaft of the first motor passes through the support and is located in the placement groove. A circular plate is fixed on the output shaft of the first motor and is rotatably connected to the support. The welding torch is located at the upper end of the support and on the side of the limiting component away from the movable component. A conveying mechanism is provided on the support. Several welding plates are provided between the conveying mechanism and the limiting component. The conveying component is used to convey the welding plates. A recycling component is also provided on the support for recycling the impeller.

[0008] By adopting the above technical solution, during operation, the operator places the impeller on the support, the moving part transports the impeller to the placement slot, the limiting component moves above the placement slot, the first motor works, and the circular plate drives the impeller to rotate. When the impeller contacts the limiting component, the initial position of the impeller is determined. When the limiting component moves, it drives the welding plate to contact the impeller. The welding gun is used to weld the welding plate and the impeller. This process is repeated. The conveying mechanism is used to transport the welding plate to the limiting mechanism, and the recovery component is used to recover the welded impeller. The welding plate welds each blade of the impeller, which increases the impeller's head.

[0009] Optionally, the moving component includes a second motor, a first lead screw, a moving plate, and two baffles. The second motor is fixedly connected to one side of the bracket along its length. The first lead screw is fixedly connected to the output shaft of the second motor and rotates coaxially with the output shaft of the second motor. The first lead screw passes through the moving plate and is threadedly connected to the moving plate. The moving plate is arranged vertically. The two baffles are located on both sides of the moving plate along its length and are arranged along the length of the bracket. Both baffles are fixedly connected to the bracket.

[0010] By adopting the above technical solution, when the impeller moves, the second motor rotates, and the first lead screw drives the moving plate to move along the length of the support, thereby conveying the impeller. The two baffles limit the impeller, which helps to reduce the probability of impeller deviation and improves the convenience and stability of impeller conveying.

[0011] Optionally, the limiting assembly includes a limiting rod, an electric push rod, and a positioning plate. The electric push rod is fixedly connected to one side of the bracket along the width direction and is set along the width direction of the bracket. The limiting rod is fixedly connected to the end of the electric push rod near the placement slot and is slidably connected to the bracket along the width direction of the bracket. The positioning plate is fixedly connected to the side of the limiting rod away from the second motor and is set perpendicular to the limiting rod.

[0012] By adopting the above technical solution, when the impeller moves into the placement slot, the electric actuator drives the limiting rod to approach the impeller in the placement slot. When the limiting rod moves, the positioning plate drives the welding plate to move. When the limiting rod is above the placement slot, the first motor rotates. When the impeller contacts the limiting rod, the initial position of the impeller is determined. The welding gun welds the welding plate and the impeller, thus completing the welding of one blade. At this time, the electric actuator drives the limiting rod away from the impeller, the first motor rotates, the circular plate drives the impeller to rotate at a specified angle, and the positioning plate drives another welding plate to approach the impeller, thus completing the welding. This cycle is repeated, improving the convenience of impeller welding and the convenience of initial impeller positioning.

[0013] Optionally, the conveying mechanism includes a first support block, a second support block, a moving rod, a first slider, a driving member, and a guide block. The first support block is fixedly connected to the upper end of the bracket and located on the side of the limiting rod away from the second motor. The first support block is arranged along the length direction of the bracket. The second support block is fixedly connected to the upper end of the bracket and located on the side of the first support block near the placement groove. The first support block and the second support block are parallel to each other. The first slider is located on the side of the first support block near the second support block and is slidably connected to the first support block along the length direction of the first support block. The moving rod is located at the upper end of the second support block and is slidably connected to the second support block along the length direction of the second support block. The upper end of the moving rod is provided with several guide grooves along the length direction. The guide block is rotatably connected to the side of the first slider near the second support block and is directly opposite the guide grooves. The end of the moving rod near the electric push rod is in contact with the welding plate. A limiting block is fixed on the side of the first slider near the guide block. The limiting block is located on the side of the guide block away from the electric push rod. The driving member is located at the upper end of the bracket and is used to drive the first slider to slide.

[0014] By adopting the above technical solution, when the welding plate needs to be transported, the driving component drives the first slider to move on the first support block. When the first slider moves towards the electric push rod, the guide block on the first slider is located in the guide groove, and the limiting block limits the guide block. Therefore, when the first slider moves, the guide block pushes the moving rod to move at the upper end of the second support block, thereby transporting the welding plate to the positioning plate, which improves the convenience of welding plate transport.

[0015] Optionally, the driving component includes a third motor, a first guide rod, and a second guide rod. The third motor is fixedly connected to the upper end of the bracket and located on the side of the first support block away from the electric push rod. The first guide rod is fixedly connected to the output shaft of the third motor and is set perpendicular to the third motor. The first guide rod and the second guide rod are vertically hinged together. The end of the second guide rod away from the first guide rod is vertically hinged to the first slider. The second guide rod is located between the first guide rod and the first slider.

[0016] By adopting the above technical solution, the third motor rotates, driving the first guide rod to rotate. The first guide rod and the second guide rod cooperate with each other to drive the first slider to move back and forth along the length of the first support block, thereby improving the ease of movement of the first slider.

[0017] Optionally, the recycling assembly includes a lifting cylinder, a horizontal moving assembly, a rectangular rod, and a locking component. A frame is fixedly mounted on the upper end of the support. The lifting cylinder is fixedly connected to the upper end of the frame. The output end of the lifting cylinder passes through the frame and is used to drive the horizontal moving assembly to lift. The rectangular rod is slidably connected to the horizontal moving assembly. The locking component is slidably connected to the rectangular rod vertically and is used to fix the impeller.

[0018] By adopting the above technical solution, the frame supports the lifting cylinder, which drives the horizontal moving component to descend. The rectangular rod below the horizontal moving component is located at the center hole of the impeller. At this time, the locking part fixes the impeller, the lifting cylinder retracts, and drives the impeller to move upward. The horizontal moving component drives the impeller to move horizontally, thereby completing the recovery of the impeller and improving the convenience of impeller recovery.

[0019] Optionally, the horizontal moving assembly includes a fourth motor, a second lead screw, a support plate, and a second slider. The support plate is fixedly connected to the output end of the lifting cylinder. The fourth motor is fixedly connected to one side of the support plate along its length. The second lead screw is fixedly connected to the output shaft of the fourth motor and is arranged along the length of the support plate. The second slider is located at the lower end of the support plate and is slidably connected to the support plate along its length. The second lead screw passes through the second slider and is threadedly connected to the second slider. A rectangular rod is fixedly connected to the lower end of the second slider.

[0020] By adopting the above technical solution, the support plate is connected to the lifting cylinder to support the fourth motor. The rotation of the fourth motor drives the second lead screw to rotate, and the second lead screw drives the second slider to slide along the length of the support plate. The second slider drives the rectangular rod to move, which in turn drives the impeller to move horizontally, thus improving the convenience of horizontal movement of the impeller.

[0021] Optionally, the locking component includes an electric telescopic rod, a third slider, two fourth guide rods, and two third guide rods. A sliding groove is vertically formed on the side of the rectangular rod away from the first motor. The third slider is located within the sliding groove and is slidably connected to the rectangular rod vertically. The electric telescopic rod is located within the sliding groove, with its upper end fixedly connected to the rectangular rod and its lower end fixedly connected to the third slider. Grooves communicating with the sliding groove are formed on both sides of the lower end of the rectangular rod along the width direction of the bracket. The third guide rod and the fourth guide rod correspond one-to-one. The third guide rod is hinged to the lower end of the third slider. The fourth guide rod is located within the groove and is slidably connected to the rectangular rod along its length. The end of the third guide rod away from the third slider is hinged to the end of the fourth guide rod near the third slider. The third guide rod is inclined from top to bottom along the direction from the third slider to the fourth guide rod.

[0022] By adopting the above technical solution, when the rectangular rod is located inside the impeller, the electric telescopic rod pushes the third slider to slide in the sliding groove. When the third slider moves down, the third guide rod pushes the fourth guide rod to slide in the groove. The fourth guide rod fits into the impeller, and the two fourth guide rods cooperate to fix the impeller, thus improving the stability of the impeller fixation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the impeller moves into the placement slot, the electric actuator drives the limit rod to approach the impeller in the placement slot. When the limit rod moves, the positioning plate drives the welding plate to move. When the limit rod is above the placement slot, the first motor rotates. When the impeller contacts the limit rod, the initial position of the impeller is determined. The welding gun welds the welding plate and the impeller, thus completing the welding of one blade. At this time, the electric actuator drives the limit rod away from the impeller, the first motor rotates, the circular plate drives the impeller to rotate at a specified angle, and the positioning plate drives another welding plate to approach the impeller, thus completing the welding. This cycle is repeated, which improves the convenience of impeller welding and the convenience of the initial positioning of the impeller.

[0025] 2. When the third motor rotates, the first guide rod and the second guide rod cooperate with each other to drive the first slider to move back and forth along the length of the first support block. When the first slider moves towards the electric push rod, the guide block on the first slider is located in the guide groove, and the limiting block limits the guide block. Therefore, when the first slider moves, the guide block pushes the moving rod to move at the upper end of the second support block, thereby conveying the welding plate to the positioning plate, which improves the convenience of welding plate conveying.

[0026] 3. When the rectangular rod is inside the impeller, the electric telescopic rod pushes the third slider to slide in the sliding groove. When the third slider moves down, the third guide rod pushes the fourth guide rod to slide in the groove. The fourth guide rod fits against the impeller. The two fourth guide rods cooperate with each other to fix the impeller, which improves the stability of the impeller fixation. Attached Figure Description

The positioning plate 33 is fixedly connected to the side of the limiting rod 31 away from the second motor 21 and is arranged perpendicular to the limiting rod 31. When the impeller moves into the placement groove 12, the electric push rod 32 drives the limiting rod 31 to move closer to the impeller in the placement groove 12. When the limiting rod 31 moves, the positioning plate 33 drives the welding plate 15 to move.

When the impeller abuts against the limiting rod 31, the initial position of the impeller is determined.

[0040] Referring to Figures 2 and 3, the welding torch 11 welds the welding plate 15 and the impeller, thus completing the welding of one blade. At this time, the electric actuator 32 drives the limiting rod 31 away from the impeller, the first motor 13 rotates, the circular plate 14 drives the impeller to rotate at a specified angle, and the positioning plate 33 drives another welding plate 15 to move closer to the impeller, thereby completing the welding. This process is repeated, which improves the convenience of impeller welding and the convenience of initial impeller positioning.

When the first slider 44 moves towards the electric push rod 32, the guide block 45 on the first slider 44 is located within the guide grooves 431, and the limiting block 46 limits the guide block 45. Therefore, when the first slider 44 moves, the guide block 45 pushes the moving rod 43 to move at the upper end of the second support block 42, thereby conveying the welding plate 15 to the positioning plate 33, improving the convenience of conveying the welding plate 15.

The second lead screw 533 passes through the second slider 534 and is threadedly connected to the second slider 534. The rectangular rod 54 is fixedly connected to the lower end of the second slider 534. The rotation of the fourth motor 532 drives the second lead screw 533 to rotate.

The extension and retraction of the electric telescopic rod 551 drives the third slider 552 to slide back and forth in the sliding groove 541.

[0047] Referring to Figure 5, the lower end of the rectangular rod 54 has grooves 542 on both sides along the width direction of the bracket 1, which are connected to the sliding groove 541.

[0048] The implementation principle of the high-lift impeller processing device for industrial pumps in this embodiment is as follows: When welding the impeller, the moving part 2 transports the impeller to the placement groove 12. The third motor 471 rotates, and the first guide rod 472 and the second guide rod 473 cooperate to drive the first slider 44 to reciprocate along the length direction of the first support block 41. When the first slider 44 moves towards the electric push rod 32, the guide block 45 and the limiting block 46 on the first slider 44 cooperate to drive the moving rod 43 to move closer to the electric push rod 32, thereby moving the welding plate 15. The material is conveyed to the positioning plate 33. The electric actuator 32 pushes the limiting rod 31 closer to the impeller. The limiting rod 31 and the positioning plate 33 work together to move the welding plate 15 closer to the impeller. The welding gun 11 welds the welding plate 15 and the impeller, thus completing the welding of one blade. At this time, the electric actuator 32 moves the limiting rod 31 away from the impeller. The first motor 13 rotates, and the circular plate 14 drives the impeller to rotate at a specified angle. The positioning plate 33 drives another welding plate 15 closer to the impeller, thus completing the welding. This process is repeated to complete the welding of each blade, thereby increasing the impeller's head.
