Description

Technical Field

[0001] This utility model relates to the field of multi-stage pump rotor processing technology, and in particular to a magnetic fast calibration frame for multi-stage pump rotors. Background Technology

[0002] The multistage pump rotor is a key rotating component in a multistage centrifugal pump used to transfer kinetic energy and drive liquid flow. It typically consists of multiple impellers and a shaft connected to them. These impellers are arranged sequentially along the axial direction, with each impeller progressively increasing the liquid pressure to achieve high-lift delivery. The precision and strength of the rotor structure directly affect the pump's operational stability and efficiency, and it is widely used in high-pressure water supply, boiler feedwater, petrochemical transportation, and other fields. Due to its complex structure and long length, the multistage pump rotor has high requirements for coaxiality and dynamic balance; therefore, a magnetic quick-calibration frame is needed during assembly and maintenance.

[0003] The magnetic quick calibration frame for multistage pump rotors is an auxiliary tool used in the assembly and maintenance of multistage centrifugal pump rotors. In existing technologies, rotor fixing usually relies on manual measurement and fixing fixtures. However, when fixing the rotor with fixtures, it is easy to damage the rotor surface, thus affecting the subsequent processing of the rotor. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-stage pump rotor magnetic quick calibration frame, which aims to improve the problem that the fixing of the rotor usually relies on fixing clamps, and fixing clamps can easily damage the rotor surface when fixing the rotor.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-stage pump rotor magnetic fast calibration frame includes a worktable and a fixed frame. The worktable has a support frame inside, and the rotor body is mounted on the upper surface of the support frame. A slidably connected irregular frame is inside the fixed frame, and a magnetic suction element is inside the irregular frame. A T-shaped rod is rotatably connected inside the irregular frame, and a slider is fixedly connected to the bottom end of the T-shaped rod. A U-shaped frame is rotatably connected inside the slider, and a slide block is rotatably connected to the outer wall of the U-shaped frame. A connecting rod is fixedly connected to the outer wall of the slide block, and a spring is fixedly connected to the outer wall of the connecting rod. The outer wall of the spring is fixedly connected inside the irregular frame, and a conical block is fixedly connected to the outer wall of the connecting rod. The outer wall of the conical block is located inside the fixed frame, and a moving component is mounted on the lower surface of the fixed frame.

[0007] Preferably, the moving component includes an electric slide table, the upper surface of which is fixedly connected to the lower surface of the fixed frame, and a slide rail is provided inside the electric slide table, the lower surface of which is fixedly connected to the upper surface of the worktable.

[0008] Preferably, the outer wall of the slider is slidably connected to the inside of the irregular frame, the inside of the slide block is located inside the irregular frame, and the outer wall of the connecting rod is slidably connected to the inside of the irregular frame.

[0009] Preferably, a second spring is fixedly connected to the lower surface of the support frame, and a circular block is fixedly connected to the lower outer wall of the second spring. The outer wall of the circular block is slidably connected to the inside of the worktable.

[0010] Preferably, an L-shaped rod is slidably connected inside the worktable, and a cylinder is fixedly connected to the outer wall of the L-shaped rod.

[0011] Preferably, the outer wall of the cylinder is slidably connected to the inside of the workbench, and the outer wall of the L-shaped rod is provided with a spring.

[0012] Preferably, one end of the spring three is fixedly connected to the inside of the workbench, and the other end of the spring three is fixedly connected to the outer wall of the cylinder.

[0013] Preferably, a trapezoidal block is fixedly connected to the outer wall of the cylinder, and the outer wall of the trapezoidal block is disposed inside the support frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the height of the magnetic component is easily adjusted by the cooperation between the fixed frame, the irregular frame, the T-shaped rod, the slider, the U-shaped frame, the slide block, the connecting rod, the spring, and the conical block, so that the magnetic component is perpendicular to the vertical center of the rotor and the attraction force is stable. This allows it to adapt to rotors of different thicknesses and facilitates the disassembly and replacement of the magnetic component, improving maintenance efficiency and reducing damage to the rotor during fixing.

[0016] 2. In this utility model, the support frame is installed and disassembled through the cooperation between spring two, round block, L-shaped rod, cylinder, spring three and trapezoidal block. This makes it easy to replace different support frames according to the length, diameter and journal position of the rotor, thereby improving the adaptability of the calibration frame. At the same time, it leaves sufficient space for the hoisting, moving in and out of the rotor, reducing the difficulty of manual handling. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a multi-stage pump rotor magnetic fast calibration frame, including a workbench 1 and a fixed frame 4. A support frame 2 is provided inside the workbench 1, and a rotor body 3 is provided on the upper surface of the support frame 2. A shaped frame 5 is slidably connected inside the fixed frame 4. A magnetic suction component 6 is provided inside the shaped frame 5. A T-shaped rod 7 is rotatably connected inside the shaped frame 5. A slider 8 is fixedly connected to the bottom end of the T-shaped rod 7. A U-shaped frame 9 is rotatably connected inside the slider 8. A slide seat 10 is rotatably connected to the outer wall of the U-shaped frame 9. A connecting rod 11 is fixedly connected to the outer wall of the slide seat 10. A spring 12 is fixedly connected to the outer wall of the connecting rod 11. The outer wall of the spring 12 is fixedly connected inside the shaped frame 5. A conical block 13 is fixedly connected to the outer wall of the connecting rod 11. The outer wall of the conical block 13 is located inside the fixed frame 4. A moving component is provided on the lower surface of the fixed frame 4.

[0026] Specifically, the rotor body 3 is designed as a common multistage pump rotor. The support frame 2 has internal grooves to hold the multistage pump rotor with its spindle. Short rods are provided around the upper perimeter of the support frame 2 to limit the rotor body 3 during magnetic attraction, preventing accidental slippage. The movement of the irregularly shaped frame 5 is restricted by the internal structure of the fixing frame 4. Multiple grooves are provided inside the fixing frame 4, through which the conical block 13 slides in and out, facilitating adjustment of the irregularly shaped frame 5's position on the fixing frame 4, or removal of the irregularly shaped frame 5 from the fixing frame 4. Below, the irregular frame 5 is composed of a square, a U-shaped plate, and a hollow block. The hollow block is used to install the magnetic suction component 6. Short rods are set inside the U-shaped frame 9 and distributed on both sides to connect with the slider 8 and the slide block 10, which facilitates the transmission of the slide block 10. The movement stroke of the slider 8, the U-shaped frame 9, and the slide block 10 forms a triangle, which helps to reduce the transmission of the U-shaped frame 9 and the slide block 10 by the weight of the T-shaped rod 7 and the slider 8. The elastic force of the spring-12 is set to be greater than the weight of the irregular frame 5 and the magnetic suction component 6, so as to avoid insufficient elastic force of the spring-12, which would affect the stable positioning of the cone block 13 on the irregular frame 5.

[0027] Reference Figure 2 The moving component includes an electric slide table 14, the upper surface of which is fixedly connected to the lower surface of the fixed frame 4, and a slide rail 15 is provided inside the electric slide table 14, the lower surface of which is fixedly connected to the upper surface of the worktable 1.

[0028] Specifically, slide rails 15 and electric slide tables 14 are provided on both sides of the workbench 1. The slide rails 15 restrict the movement of the electric slide tables 14. The electric slide tables 14 on both sides are started at the same time, which facilitates the synchronous movement of the fixed frames 4 on both sides.

[0029] Reference Figure 3 The outer wall of the slider 8 is slidably connected to the inside of the irregular frame 5, the inside of the slide block 10 is set inside the irregular frame 5, and the outer wall of the connecting rod 11 is slidably connected to the inside of the irregular frame 5.

[0030] Specifically, the movement of the slider 8 is limited by the interior of the irregular frame 5, and the slide 10 moves on the guide rail provided inside the irregular frame 5, thereby supporting and restricting the movement of the slide 10. The movement of the connecting rod 11 is also restricted by the interior of the irregular frame 5.

[0031] Reference Figure 4 and Figure 5A second spring 16 is fixedly connected to the lower surface of the support frame 2. A circular block 17 is fixedly connected to the lower outer wall of the second spring 16. The outer wall of the circular block 17 is slidably connected to the inside of the worktable 1. An L-shaped rod 18 is slidably connected to the inside of the worktable 1. A cylinder 19 is fixedly connected to the outer wall of the L-shaped rod 18. The outer wall of the cylinder 19 is slidably connected to the inside of the worktable 1. A third spring 20 is provided on the outer wall of the L-shaped rod 18. One end of the third spring 20 is fixedly connected to the inside of the worktable 1, and the other end of the third spring 20 is fixedly connected to the outer wall of the cylinder 19. A trapezoidal block 21 is fixedly connected to the outer wall of the cylinder 19. The outer wall of the trapezoidal block 21 is located inside the support frame 2.

[0032] Specifically, spring 16 and block 17 are moved downwards along the interior of workbench 1, causing the lower outer wall of support frame 2 to slide into the interior of workbench 1. The lower surface of block 17 contacts the inner bottom wall of workbench 1, compressing spring 16 and pushing trapezoidal block 21. This causes L-shaped rod 18 and cylinder 19 to move forward, compressing spring 20. After support frame 2 moves to the appropriate position, spring 20 causes trapezoidal block 21 to slide into the interior of support frame 2 for positioning. Simultaneously, the elasticity of magnetic suction 6 creates vertical and horizontal compression to position support frame 2. The above structure is provided around all four sides of support frame 2 to improve the stability of support frame 2 installation. The movement of cylinder 19 is restricted by the interior of workbench 1, and the movement of L-shaped rod 18 is restricted by the interior of workbench 1. The movement of cylinder 19 within workbench 1 provides support for the movement of trapezoidal block 21.

[0033] Working principle: When using this calibration frame, the rotor body 3 is placed on the upper surface of the support frame 2 using a lifting tool or other tools. Then, the electric slides 14 on both sides of the worktable 1 are started simultaneously, so that the electric slides 14 on both sides move synchronously towards the center of the support frame 2 via the slide rail 15. Using the magnetic suction 6 set inside the irregular frame 5, when the irregular frame 5 on both sides approaches the rotor body 3, the magnetic suction 6 is activated. Through the attraction of the magnetic suction 6 on both sides, the rotor body 3 is placed in the center position of the support frame 2, thereby fixing the rotor body 3, which is convenient for other equipment or tools to calibrate the rotor body 3, or to assemble and process the rotor body 3.

[0034] By pressing the T-shaped rod 7 downwards, the U-shaped frame 9 is driven by the slider 8, causing the U-shaped frame 9 to move downwards. At the same time, the short rod inside the U-shaped frame 9 connects with the slider 8 and the slide block 10, causing the U-shaped frame 9 to move towards the T-shaped rod 7. This drives the slide block 10 to move towards the T-shaped rod 7 on the guide rail inside the irregular frame 5, which in turn drives the connecting rod 11 and the conical block 13 to move towards the T-shaped rod 7, compressing the spring 12. The conical block 13 then disengages from the inside of the fixed frame 4, no longer limiting the irregular frame 5, making it convenient to adjust the position of the irregular frame 5 or remove the irregular frame 5.

[0035] By pulling the L-shaped rod 18 forward, the cylinder 19 and trapezoidal block 21 are moved forward, squeezing the spring 20. After the trapezoidal block 21 slides out of the support frame 2, the elastic force of the spring 16 pushes the support frame 2 upward, making it easy to hold the support frame 2 and slide the spring 16 and the cylinder 17 out of the workbench 1, thereby disassembling the support frame 2. During use, this calibration frame not only adjusts the height of the irregular frame 5, but also enables the installation and disassembly of the support frame 2, facilitating cleaning and maintenance.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
