Description

Technical Field

[0001] This utility model relates to the field of rotor technology, and in particular to a rotor perpendicularity detection device. Background Technology

[0002] In the machining and assembly process, accurate detection of rotor perpendicularity is crucial to ensuring the operational stability and reliability of rotating equipment such as motors and steam turbines.

[0003] Most existing rotor verticality testing devices on the market generally use traditional methods such as bolt tightening and clamping when fixing the rotor. Taking bolt tightening as an example, the rotor is positioned and fixed by tightening multiple bolts one by one. The whole process is not only cumbersome, but also consumes a lot of time and manpower because the tightness of the bolts needs to be adjusted many times to ensure that the rotor center is aligned with the testing benchmark. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing rotor perpendicularity testing devices on the market usually use bolt tightening or clamping to fix the rotor. Taking bolt tightening as an example, multiple bolts are turned for positioning and fixing. This process is complicated and requires multiple adjustments of the bolt tightness to ensure that the rotor center is aligned with the testing reference, resulting in a large consumption of time and manpower. Therefore, we propose a rotor perpendicularity testing device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a rotor verticality detection device, comprising an operating table, a support rod fixedly connected to the top of the operating table, a detector slidably connected to the surface of the support rod, a sleeve fixedly connected to the top of the operating table, a connecting rod rotatably connected inside the sleeve, a placement plate fixedly connected to the top of the connecting rod, two movable slots opened on the top of the placement plate, movable blocks slidably connected inside the movable slots, a positioning plate fixedly connected to the top of the movable blocks, an L-shaped plate fixedly connected to one side of the movable blocks, a fixing rod fixedly connected to the bottom of the L-shaped plate, movable slots opened on both sides of the placement plate, the surface of the fixing rod slidably connected to the interior of the movable slots, and slots opened at both ends of the fixing rod;

[0006] The slot is equipped with a fixing mechanism for fixing the position of the positioning plate.

[0007] Preferably, the fixing mechanism includes a storage spring installed inside the slot, one end of the storage spring is fixedly connected to a locking block, and multiple extension plates are fixedly connected to both sides of the placement plate, with a locking groove opened at one end of each extension plate.

[0008] Preferably, the surface of the card block is slidably connected to the interior of the card slot, and the external shape of the card block matches the internal shape of the card slot.

[0009] Preferably, there are sliding grooves on both sides of the inner cavity of the slot, and sliders are fixedly connected to both sides of the locking block.

[0010] Preferably, the inner wall of the positioning plate is fixedly connected with an anti-slip pad.

[0011] Preferably, limit grooves are provided at both ends of the inner cavity of the moving groove, and limit blocks are fixedly connected to both ends of the moving block.

[0012] Preferably, a thrust spring is fixedly connected to the other side of the movable block, and one side of the thrust spring is fixedly connected to the inside of the movable groove.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, the operator places the rotor on top of the placement tray, then moves the L-shaped plate, causing the positioning plate to move and clamp the rotor's surface. The combination of a storage spring and a locking block allows the locking block to be inserted into a slot by the spring force, thus fixing the position of the positioning plate. This makes rotor positioning faster, saves time, and improves work efficiency. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figures 1-5 As shown, this utility model provides a technical solution: a rotor verticality detection device, including an operating table 1, a support rod 2 fixedly connected to the top of the operating table 1, a detector 3 slidably connected to the surface of the support rod 2, a sleeve 4 fixedly connected to the top of the operating table 1, a connecting rod 5 rotatably connected inside the sleeve 4, a placement plate 6 fixedly connected to the top of the connecting rod 5, two movable grooves 7 opened on the top of the placement plate 6, a movable block 8 slidably connected inside the movable grooves 7, a positioning plate 9 fixedly connected to the top of the movable block 8, an L-shaped plate 10 fixedly connected to one side of the movable block 8, a fixing rod 11 fixedly connected to the bottom of the L-shaped plate 10, movable grooves 12 opened on both sides of the placement plate 6, the surface of the fixing rod 11 slidably connected to the inside of the movable grooves 12, and slots 15 opened at both ends of the fixing rod 11. A fixing mechanism is installed to fix the position of the positioning plate 9. The fixing mechanism includes a storage spring 16 installed inside the slot 15. One end of the storage spring 16 is fixedly connected to a locking block 17. Multiple extension plates 13 are fixedly connected to both sides of the placement plate 6. One end of the extension plate 13 is provided with a slot 14. The operator places the rotor on the top of the placement plate 6, and then moves the L-shaped plate 10, which drives the positioning plate 9 to move. The positioning plate 9 clamps and positions the surface of the rotor. Then, through the cooperation of the storage spring 16 and the locking block 17, the locking block 17 can be inserted into the slot 14 by the elastic force of the storage spring 16, fixing the position of the positioning plate 9. This makes the rotor positioning faster, saves the operator's time, and improves work efficiency.

[0023] Reference Figure 3 and Figure 5 As shown, in this embodiment: the surface of the locking block 17 is slidably connected to the inside of the locking groove 14, and the external shape of the locking block 17 matches the internal shape of the locking groove 14. Because the external shape of the locking block 17 matches the internal shape of the locking groove 14, the locking block 17 can be firmly locked into the locking groove 14, avoiding the shaking of the positioning plate 9 during the movement, and further enhancing the stability of the rotor.

[0024] Reference Figure 5As shown in this embodiment: both sides of the inner cavity of the slot 15 have sliding grooves 18, and both sides of the locking block 17 are fixedly connected with sliders 19. The sliders 19 can slide inside the sliding grooves 18. Due to the cooperation between the sliders 19 and the sliding grooves 18, the locking block 17 is more stable when sliding inside the locking groove 14, which further avoids the shaking of the positioning plate 9 during the movement and improves the stability of the rotor.

[0025] Reference Figure 4 As shown in this embodiment: the inner wall of the positioning plate 9 is fixedly connected with an anti-slip pad 20. The anti-slip pad 20 increases the friction between the positioning plate 9 and the rotor, thereby preventing the rotor from sliding or shifting during the detection process and ensuring the accuracy of the detection.

[0026] Reference Figure 3 and Figure 4 As shown in this embodiment: both ends of the inner cavity of the moving groove 7 are provided with limiting grooves 21, and both ends of the moving block 8 are fixedly connected with limiting blocks 22. The limiting blocks 22 can be inserted into the inside of the limiting grooves 21. Due to the cooperation between the limiting blocks 22 and the limiting grooves 21, the moving block 8 is limited, making the moving block 8 more stable when moving inside the moving groove 7, avoiding the displacement of the moving block 8 during the movement, thereby ensuring that the positioning plate 9 can move along a specific path.

[0027] Reference Figure 4 As shown in this embodiment: a thrust spring 23 is fixedly connected to the other side of the moving block 8. One side of the thrust spring 23 is fixedly connected to the inside of the moving groove 7. The thrust spring 23 can generate a thrust on the moving block 8, so that the positioning plate 9 can automatically reset when it is not subjected to external force, which facilitates quick positioning for the next use.

[0028] Working principle: The operator places the rotor on top of the placement plate 6, then moves the L-shaped plate 10, causing the positioning plate 9 to move. The positioning plate 9 clamps and positions the rotor. Then, through the cooperation of the storage spring 16 and the locking block 17, the locking block 17 is inserted into the slot 14 by the elastic force of the storage spring 16, fixing the position of the positioning plate 9. This makes rotor positioning faster, saving operator time and improving work efficiency. Because the external shape of the locking block 17 matches the internal shape of the slot 14, the locking block 17 can be firmly locked into the slot 14, preventing the positioning plate 9 from shaking during movement and further enhancing the stability of the rotor. The slider 19 can slide inside the slide groove 18. Due to the interaction between the slider 19 and the slide groove 18... The coordinated design makes the locking block 17 more stable when sliding inside the locking slot 14, further preventing the positioning plate 9 from shaking during movement and improving the stability of the rotor. The anti-slip pad 20 increases the friction between the positioning plate 9 and the rotor, thereby preventing the rotor from sliding or shifting during the detection process and ensuring the accuracy of the detection. The limiting block 22 can be locked inside the limiting groove 21. Due to the coordinated design of the limiting block 22 and the limiting groove 21, the moving block 8 is limited, making the moving block 8 more stable when moving inside the moving groove 7 and preventing the moving block 8 from deviating during the movement process. This ensures that the positioning plate 9 can move along a specific path. The thrust spring 23 can generate thrust on the moving block 8, so that the positioning plate 9 can automatically reset when it is not subjected to external force, which facilitates quick positioning for the next use.

[0029] 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.
