Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump processing technology, and in particular to a high-precision processing equipment for centrifugal pumps. Background Technology

[0002] Centrifugal pumps operate by using the rotation of an impeller to create centrifugal motion in water. The basic structure of a centrifugal pump consists of six parts: impeller, pump body, pump shaft, bearings, sealing rings, and stuffing box. Currently, many components of centrifugal pumps require punching during production and assembly. Hydraulic punching, as a novel punching method, offers unparalleled advantages over traditional processing techniques for punching hollow parts and parts with curved axes. Hydraulic punching eliminates the need for a die during the entire punching process, which is highly advantageous for machining parts with small internal dimensions or curved axes where a die cannot be placed internally.

[0003] Existing high-precision machining equipment for centrifugal pumps can only fix the two sides of the centrifugal pump components, and cannot fix the four sides of the components. This makes the components prone to movement during punching, resulting in large punching deviations, which greatly reduces product quality and limits their practicality. Therefore, we propose a high-precision machining equipment for centrifugal pumps to solve this problem. Utility Model Content

A fixing plate 15 is fixedly mounted on the inside of each of the multiple L-shaped plates 14. A rubber pad 16 is fixedly mounted on the inside of each of the multiple fixing plates 15.

[0022] In this embodiment, a placement platform 3 is fixedly installed on the top of the base 1. The top of the placement platform 3 has multiple moving holes 18. The outer sides of multiple L-shaped plates 14 are slidably connected to the corresponding moving holes 18. Two electric push rods 25 are fixedly installed on the inner side of the top of the placement platform 3. The output ends of the two electric push rods 25 are fixedly connected to the same support plate 24. A second motor 26 is fixedly installed on the top of the support plate 24. The output end of the second motor 26 is fixedly connected to a polishing rod 27. The top of the placement platform 3 has a through hole 28 that matches the polishing rod 27, so that the polishing rod 27 can be moved by the electric push rod 25.

[0023] In this embodiment, a fixed frame 2 is fixedly installed on the top of the base 1, and a hydraulic cylinder 19 is fixedly installed on the inner side of the top of the fixed frame 2. A movable plate 20 is fixedly connected to the output end of the hydraulic cylinder 19, and the bottom of the movable plate 20 is fixedly installed on the top of the punching rod 21, so as to facilitate the movement of the punching rod 21 by the hydraulic cylinder 19.

[0024] In this embodiment, the bottom end of the threaded rod 8 is rotatably installed inside the bottom wall of the groove, and multiple telescopic columns 17 are fixedly installed on the top of the base 1. The tops of the multiple telescopic columns 17 are fixedly installed on the bottom of the same connecting plate 10. A first motor 4 is fixedly installed on one side of the base 1.

[0026] In this embodiment, during use, the centrifugal pump components are first placed at the top center of the placement platform 3. Then, by starting motor 4, the rotating shaft 5 is driven to rotate, which in turn drives bevel gear 6 to rotate, thereby driving bevel gear 7, which meshes with bevel gear 6, to rotate.

This prevents the centrifugal pump components from moving during punching, making the punching of the centrifugal pump components more accurate. This significantly improves product quality and broadens practicality. After the centrifugal pump components are fixed, the hydraulic cylinder 19 is activated, which moves the moving plate 20 and the T-shaped slider 22 along the T-shaped groove 23. This further moves the punching rod 21, causing it to punch holes in the centrifugal pump components. After punching, the above operation is repeated in reverse, moving the punching rod 21 away from the centrifugal pump components. After punching, there will be burrs inside the punched holes of the centrifugal pump components. The electric push rod 25 is then activated, which moves the support plate 24, which in turn moves the second motor 26 and the grinding rod 27. The grinding rod 27 passes through the through hole 28 and reaches the punched hole inside the centrifugal pump components. Then, the second motor 26 is activated, which rotates the grinding rod 27, causing it to grind the inside of the punched holes in the centrifugal pump components, resulting in better processing quality of the centrifugal pump components.
