[0031] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some technical features well known to those skilled in the art are not described.

[0032] Unless otherwise defined, the directions such as up, down, left, right, front, back, inner and outer involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figure shown by the present utility model, and are hereby explained together.

[0033] This embodiment provides an adjustable measuring tool for measuring the chord distance of stator dove-tail ribs as shown in Figures 1 to 5 Figure, which includes: a stator dove-tail rib measuring plate 1, a dove-tail rib template 2, a measuring dial indicator 4, and a centripetal driving mechanism 10.

[0034] In this embodiment, the stator dove-tail rib measuring plate 1 is used to measure the chord distance between two adjacent stator dove-tail ribs.

[0035] In this embodiment, two dove-tail rib templates 2 are symmetrically arranged and slidably connected to the top of the stator dove-tail rib measuring plate 1. A stator dove-tail rib part 3 is clamped on the opposite side of each of the two dove-tail rib templates 2; the dove-tail rib template 2 serves as a fixture for the stator dove-tail rib part 3 and can clamp the actual stator dove-tail rib part 3 so that they can be accurately placed at the measuring position. This ensures the consistency and accuracy of the measurement.

[0036] In this embodiment, the dial indicator 4 is arranged between two stator dove-tail rib members 3 and can move linearly and be disassembled and adjusted in orientation on the stator dove-tail rib measuring plate 1. One side of the dial indicator 4 has a measuring end 5; the dial indicator 4 is used to directly read the chord distance between two stator dove-tail rib members 3. It can adapt to different measurement requirements by moving and adjusting the orientation. The measuring end 5, as a part of the dial indicator 4, is a component that directly contacts and senses the position change of the stator dove-tail rib member 3, thereby converting the measured position chord distance into a readable pointer movement.

[0037] In this embodiment, the centripetal driving mechanism 10 is embedded in the stator dove-tail rib measuring plate 1 to centripetally drive two dove-tail rib templates 2, so as to meet the use of different spacings between two stator dove-tail rib members 3. The centripetal driving mechanism 10 can drive the dove-tail rib template 2 and the stator dove-tail rib member 3, which can improve the use efficiency and meet different use occasions. At the same time, the design of the detachable and adjustable orientation of the dial indicator 4 can measure the stator dove-tail rib members 3 at different positions.

[0038] In this embodiment, a rectangular moving frame 6 is sleeved at the middle position of the stator dove-tail rib measuring plate 1. The rectangular moving frame 6 can slide linearly on the stator dove-tail rib measuring plate 1, and the dial indicator 4 is arranged above the rectangular moving frame 6. The rectangular moving frame 6 provides a frame for the dial indicator 4 to slide linearly on the stator dove-tail rib measuring plate 1, ensuring the stability and accuracy during the measurement process.

[0039] In this embodiment, the lower housing of the dial indicator 4 is integrally connected with the measuring end 5. A threaded through hole 11 is formed in one outer wall of the rectangular moving frame 6, and a screw member 12 is threadedly connected in the threaded through hole 11. One end of the screw member 12 is fixed with a locking knob 7. The locking knob 7 fixes the position of the rectangular moving frame 6 relative to the stator dove-tail rib measuring plate 1 through the screw member 12 to prevent accidental movement during the measurement process. The screw member 12 is connected to the locking knob 7 and the rectangular moving frame 6. When the locking knob 7 rotates, the screw member 12 will advance or withdraw to fix or loosen the rectangular moving frame 6.

[0040] In this embodiment, when the locking knob 7 is tightened, the locking knob 7 drives the screw member 12 to rotate in the threaded through hole 11, and the screw member 12 can pass through the threaded through hole 11 to squeeze and lock the stator dove-tail rib measuring plate 1.

[0041] In this embodiment, a clamping groove 13 is formed on the top surface of the rectangular moving frame 6. A plurality of positioning key grooves 14 are formed in an annular array on the inner wall of the circumferential side of the clamping groove 13, and a magnet block 15 is bonded to the inner bottom wall of the clamping groove 13. The clamping groove 13 is arranged on the rectangular moving frame 6 and cooperates with the clamping convex block 16 at the bottom of the measuring dial indicator 4 to ensure that the measuring dial indicator 4 is firmly fixed in the correct position. The magnet block 15 cooperates with the magnet sheet at the bottom of the clamping convex block 16 to enhance the fixing effect of the measuring dial indicator 4 by magnetic force.

[0042] In this embodiment, a clamping convex block 16 adapted to be clamped with the clamping groove 13 is fixed to the bottom surface of the plate member at the lower part of the measuring dial indicator 4. A plurality of positioning key blocks 17 that are integrally connected in an annular array on the circumferential side of the clamping convex block 16 are clamped with the positioning key grooves 14. The positioning key blocks 17 cooperate with the positioning key grooves 14 to prevent the measuring dial indicator 4 from rotating relative to the rectangular moving frame 6.

[0043] In this embodiment, when the clamping convex block 16 is clamped into the clamping groove 13, the magnet sheet bonded to the bottom surface of the clamping convex block 16 magnetically attracts the magnet block 15 for the stable installation of the measuring dial indicator 4.

[0044] In this embodiment, detachable end plates 9 are installed at both ends of the stator dovetail rib measuring plate 1 by screws. A stroke chute 18 is formed inside the stator dovetail rib measuring plate 1, and the centripetal driving mechanism 10 is arranged in the stroke chute 18.

[0045] In this embodiment, the centripetal driving mechanism 10 includes a double-headed screw 19 that rotates in the stroke chute 18 and whose two ends are rotatably connected to the two detachable end plates 9, external thread paths 23 arranged at both ends of the double-headed screw 19 and having opposite thread directions, a slider member 21 penetrated and connected by the two external thread paths 23 of the double-headed screw 19, and a sliding seat 20 installed on the top surface of the slider member 21 by screws. The detachable end plates 9 are located at both ends of the stator dovetail rib measuring plate 1, supporting the installation of the centripetal driving mechanism 10 and also facilitating replacement and maintenance. The double-headed screw 19 drives the slider member 21 to move along the stroke chute 18 through a rotating action, thereby adjusting the distance between the dovetail rib templates 2. The sliding seat 20 is installed on the top surface of the slider member 21 and is connected to the dovetail rib template 2 through an installation ear plate 24 and moves along with the movement of the slider member 21.

[0046] In this embodiment, the slider member 21 moves linearly in the stroke chute 18. One end of the double-headed screw 19 extends to the outside of the detachable end plate 9 and is fixed with an adjusting knob 8. The slide base 20 makes sliding friction contact with the top surface of the stator dovetail rib measuring plate 1. At the lower part of the back of each dovetail rib template 2, mounting ear plates 24 are symmetrically welded. The mounting ear plates 24 are connected to the slide base 20 by screws. The detachable installation method of the dovetail rib template 2 can not only replace the dovetail rib templates 2 of different sizes, but also adjust the direction to meet the use in different measurement occasions. The detachable design of the slide base 20 helps to replace different slide bases 20 to meet the installation and use of different dovetail rib templates 2. When the adjusting knob 8 is screwed, the double-headed screw 19 can be driven to rotate in the stroke chute 18.

[0047] Working principle:

[0048] For this adjustable measuring tool for measuring the chord distance of the stator dovetail ribs, all components are correctly installed on the stator dovetail rib measuring plate 1. According to the actual size of the stator dovetail rib part 3 to be measured, the stator dovetail rib parts 3 to be measured are respectively placed into the dovetail rib card slots 22 in two relatively arranged dovetail rib templates 2 to ensure that they are firmly clamped and in the correct measurement position. The adjusting knob 8 is used to rotate the double-headed screw 19. Since the two ends of the double-headed screw 19 have external thread paths 23 in opposite directions, it will drive the slider members 21 on both sides to move inwards or outwards synchronously. The slider members 21 drive the slide base 20 and the dovetail rib templates 2 connected thereto to move along the stroke chute 18, so as to adjust the distance between the two dovetail rib templates 2 to adapt to the size of the workpiece to be measured. Once the appropriate spacing is adjusted so that the measuring end 5 of the measuring dial indicator 4 touches the surface of one of the stator dovetail rib parts 3.

[0049] Rotate the locking knob 7 to make the screw member 12 pass through the threaded through hole 11 on the square moving frame 6 and press the stator dovetail rib measuring plate 1 to ensure that the square moving frame 6 will not be displaced. Place the measuring dial indicator 4 above the square moving frame 6 and insert the clamping convex block 16 at the bottom of the measuring dial indicator 4 into the clamping groove 13. The positioning key block 17 in the clamping convex block 16 and the positioning key groove 14 cooperate to prevent the measuring dial indicator 4 from rotating. At the same time, the magnet block 15 is attracted to the magnet sheet at the bottom of the clamping convex block 16 to further fix the position of the measuring dial indicator 4.

[0050] Record the reading of the measuring dial indicator 4 at this time as the starting point, and continue to move the square moving frame 6 until the measuring end 5 touches the surface of the other stator dovetail rib part 3, and record the reading of the measuring dial indicator 4 again. The difference between the two readings is the chord distance between the two stator dovetail rib parts 3.

[0051] If it is necessary to measure multiple positions or stator dove-tail rib parts 3 of different specifications, repeat the above steps and adjust the measurement spacing and measurement positions according to the actual situation.
