Description

Technical Field

[0001] This invention relates to the field of shaft component inspection, specifically rotor runout detection equipment. Background Technology

[0002] Rotor runout testing essentially confirms whether the rotor truly moves around its ideal axis when rotating. Therefore, it is a key testing method for evaluating rotor machining quality, assembly accuracy, and operational stability.

[0003] Existing rotor runout detection devices generally employ fixed-gap support structures or non-adjustable support components. Because both the support spacing and height lack adjustability, when different rotors have different end diameters, it is often necessary to replace the brackets with different sizes or use temporary shims to adapt the installation. This not only increases the complexity of the clamping process but also easily leads to rotor misalignment at the support position, making it difficult to ensure good coaxiality, thus affecting the reference stability of runout measurements and the accuracy of the measurement data.

[0004] Therefore, rotor runout detection equipment is provided to address the above-mentioned problems. Summary of the Invention

[0005] To address the problem in existing technologies where rotor misalignment at the support position is easily caused, making it difficult to ensure good coaxiality and thus affecting the reference stability and accuracy of runout measurement data, this invention provides rotor runout detection equipment.

[0006] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0007] The present invention provides a rotor runout detection equipment, including a base guide rail, on which two support components are slidably connected, and each of the two support components is provided with a placement component. Each placement component has a placement cavity with a "V" shaped structure at its top. The placement component slides in a vertical position and is used to place the end of the workpiece.

[0008] After sliding, the support component is fixed in position on the base guide rail by a limiting member, and the placement component is fixed in position after vertical sliding by an adjusting member;

[0009] One of the support components is provided with a clamping component for holding or placing a dial indicator, and the dial indicator fixed by the clamping component can move in at least three mutually perpendicular directions.

[0010] The equipment features adjustable support components that allow for both close proximity and distance, as well as height-adjustable placement, enabling better placement of rotors with different diameters at both ends, facilitating the measurement of rotor runout data.

[0011] By using an adjustable clamping component to position the dial indicator, its position can be controlled, and it can be simply picked up when needed.

[0012] In this technical solution, the support component includes a sliding support, which is slidably connected to the base guide rail. The top of the sliding support has a first through groove for setting the placement component, and the middle area of ​​the sliding support has a second through groove. The solid structure of the sliding support between the first through groove and the second through groove forms a crossbeam, and the adjustment component is set on the crossbeam.

[0013] The distance between the two sliding supports can be adjusted by sliding them on the base guide rail.

[0014] In this technical solution, the placement component includes a support block. The two sides of the support block are slidably connected to the lifting grooves on the two inner walls of the first through groove. The top of the support block is recessed downward to form two symmetrically arranged support slopes. The two support slopes together form a placement cavity.

[0015] The support block slides inside the lifting grooves on the two inner walls of the first through groove, thereby adjusting the height of the support block.

[0016] In this technical solution, the adjusting component is a first fixing component or a second fixing component. The first fixing component is a screw rod arranged vertically. The screw rod passes through the crossbeam vertically and is connected to the crossbeam by threaded engagement. The top of the screw rod is connected to the bottom side wall of the support block.

[0017] The second fixing member includes a support rod arranged vertically, which passes through the crossbeam and is fixedly connected at its top to the bottom side wall of the placement block, and slidably connected at its bottom to the guide sleeve. A locking bolt is inserted into the surface of the guide sleeve, which passes through the side wall of the guide sleeve and is threadedly engaged with the side wall of the guide sleeve. The end of the locking bolt can abut against the outer wall of the support rod. The guide sleeve is fixed to the inner wall of the second through groove by the rod.

[0018] A buffer spring is fitted at the sliding connection between the support rod and the guide sleeve.

[0019] By rotating the screw, the screw is pushed to move vertically through the thread engagement, thereby causing the support block to move up or down.

[0020] The position of the support rod is changed by sliding it on the surface of the crossbeam and the guide sleeve, which in turn moves the support block vertically. The position of the support block is fixed by locking the support rod and the guide sleeve with locking bolts.

[0021] In this technical solution, the limiting component includes a T-block and a fixing bolt. The T-block is slidably connected to the inside of the movable groove on the base guide rail. The fixing bolt penetrates the bottom sidewall of the second through groove vertically and extends into the threaded hole on the T-block. The threaded hole and the fixing bolt are connected by thread engagement.

[0022] Rotate the fixing bolt until it is fully screwed into the T-block, pressing the T-block tightly against the top inner wall of the sliding groove, thus fixing the position of the sliding support on the base guide rail.

[0023] In this technical solution, the first clamping assembly includes a plurality of retractable first adjusting rods, and the ends of two adjacent first adjusting rods are movably connected by a connecting part.

[0024] One end of each of the two outermost first adjusting rods is fixedly connected to a moving block, which is slidably connected to an adjusting guide rail distributed vertically. The adjusting guide rail is fixed to the outer wall of one of the sliding supports. The other end of the first adjusting rod is connected to a clamping unit that holds the dial indicator.

[0025] In this technical solution, the connecting part includes a connecting cover with a spherical structure and a connecting ball. The connecting cover covers more than half of the surface area of ​​the connecting ball, and the connecting ball rotates inside the connecting cover. The ends of two adjacent first adjusting rods are respectively fixedly connected to the connecting cover and the connecting ball.

[0026] A damping layer is fixed to the inner wall of the connecting outer casing and adheres to the surface of the connecting ball. The first adjusting rod consists of two rods of different diameters that slide and fit together. A damping layer is also provided on the inner wall of the outer rod, and the damping layer is made of a material with a high coefficient of surface friction. This creates damped motion between the connecting ball and the connecting outer casing, and between the two rods of the first adjusting rod sliding together. Without external interference, the connecting ball does not rotate inside the connecting outer casing, and the first adjusting rod does not extend or retract.

[0027] A damping layer is also provided on the inner wall of the adjusting guide rail, so that the moving block makes damped movement inside the adjusting guide rail.

[0028] The damping layer prevents relative movement of the various moving areas of the first clamping component when no external force is applied, so that when the dial indicator is not in use, it will remain in the position placed by the user after the last use.

[0029] In this technical solution, the clamping unit includes a mounting frame, on which two symmetrically arranged bearing arc plates are fixed. A first sliding rod is slidably inserted into the bearing arc plate, and a first clamping arc plate is fixed to the end of the first sliding rod. A limiting spring is sleeved on the surface of the first sliding rod.

[0030] The two ends of the limiting spring are fixed to the first sliding rod and the bearing arc plate respectively. The dial indicator is clamped between the two first clamping arc plates. Through the reaction force of the limiting spring, the first clamping arc plate is pressed tightly against the outer wall of the dial indicator.

[0031] In this technical solution, the second clamping component mounting part includes an arc-shaped guide rail. A movable strip plate with the same arc-shaped structure is slidably connected to the inner ring side wall of the arc-shaped guide rail. Near the inner ring end of the movable strip plate, it is connected to the placement unit for placing a dial indicator via a retractable second adjusting rod. The second adjusting rod is arranged radially along the arc-shaped guide rail and the movable strip plate.

[0032] The central angles of the arc-shaped guide rail and the moving plate are both greater than 90°, and the notch of the arc-shaped guide rail is preferably set facing upwards;

[0033] The arc-shaped guide rail is slidably connected to the base guide rail via a sliding part.

[0034] In this technical solution, the sliding part includes two symmetrically arranged bearing guide rails. The two ends of the bearing guide rails are fixed to the base guide rails by vertical rods (not shown in the figure). The bearing guide rails pass through the sliding support, that is, the sliding support can slide on the bearing guide rails. A bearing slider is slidably connected to the bearing guide rails, and the bearing slider is connected to the outer wall of the bearing guide rails by rods.

[0035] By utilizing the sliding of the moving strip inside the arc-shaped guide rail and the length of the moving strip itself, the moving strip can move in a circular trajectory on the arc-shaped guide rail, thus making circumferential movement on the rotor surface.

[0036] Meanwhile, the arc-shaped guide rail can move along the load-bearing guide rail, thus enabling the dial indicator to move in different directions.

[0037] In this technical solution, the placement unit includes a placement shell, which is connected to the end of the second adjusting rod. Two symmetrically arranged second sliding rods are slidably inserted into the side wall of the placement shell. A second clamping arc plate is fixed to the end of the second sliding rod, and a limit spring is sleeved on the surface of the second sliding rod.

[0038] The reaction force of the limiting spring causes the two second clamping arc plates to clamp and fix on the dial indicator.

[0039] The sliding connection of the second adjusting rod is provided with a damping layer that has the same structure as the sliding connection of the first adjusting rod, and damping layers are also provided on the outer wall of the bearing guide rail and the inner wall of the arc-shaped guide rail.

[0040] This technical solution also includes a leveling component, which includes a bearing plate set on top of two support components. Guide telescopic rods are fixed at the four corners of the bottom side wall of the bearing plate. The bottom of the guide telescopic rod is flush with the bottom side wall of the base guide rail or fixedly connected to the base guide rail through rods. A support spring is sleeved on the surface of the guide telescopic rod, and the two ends of the support spring are fixedly connected to the two sides of the guide telescopic rod that slide and extend.

[0041] The bottom sidewalls of the bearing plate are slidably connected to both sides, and the bottom ends of the connecting vertical rods are fixed with pressure plates distributed in the horizontal direction.

[0042] The two adjusting members include a first fixing member and a second fixing member.

[0043] Position the two support blocks on the same horizontal line, or close to the same horizontal line. Place the two ends of the rotor on the two placement cavities respectively, with the side with the larger diameter placed on the support block with the second fixing member. Then slide the connecting vertical rod until it slides to the surface of one section of the cylindrical structure of the rotor. Next, press down on the bearing plate, which moves downward accordingly. Then rotate the locking bolt to disengage it from the surface of the support rod. At this point, the rotor is supported by the buffer spring. Continue to press down on the bearing plate, which moves downward synchronously with it. The lower pressure plate gradually comes into contact with the top surface of the cylindrical structure of the rotor until the bottom end of the bearing plate is completely in contact with the top surface of the cylindrical structure of the rotor. At this point, the entire rotor is in a horizontal position. Then reverse the locking bolt to fix the support rod.

[0044] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0045] The positive and progressive effects of this invention are as follows:

[0046] By incorporating support components that can move closer or further apart and height-adjustable mounting elements, the overall clamping dimensions can be flexibly adjusted according to the difference in the outer diameters at both ends of the rotor being measured, ensuring the rotor remains stably and coaxially supported within the device. This multi-dimensional adjustment capability allows for compatibility with rotors of different specifications without the need to replace dedicated brackets, effectively improving clamping adaptability.

[0047] At the same time, it places the rotor in a more reliable and reasonable support position, thereby providing more accurate reference conditions for subsequent runout detection and improving the reliability and repeatability of runout measurement data. Attached Figure Description

[0050] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0051] like Figure 1 and Figure 2 As shown, the rotor runout detection equipment includes a base guide rail 1, on which two support components are slidably connected, and each of the two support components is provided with a placement component. The top of each placement component is provided with a placement cavity in a "V" shape. The placement component slides in a vertical position and is used to place the end of the workpiece.

[0052] After sliding, the support component is fixed in position on the base guide rail 1 by the limiting component, and the placement component is fixed in position after vertical sliding by the adjusting component;

[0053] One of the support components is provided with a clamping component for holding or placing a dial indicator, and the dial indicator fixed by the clamping component can move in at least three mutually perpendicular directions.

[0054] The equipment features adjustable support components that allow for both close proximity and distance, as well as height-adjustable placement, enabling better placement of rotors with different diameters at both ends, facilitating the measurement of rotor runout data.

[0055] By using an adjustable clamping component to position the dial indicator, its position can be controlled, and it can be simply picked up when needed.

[0056] like Figure 3 As shown, the support assembly includes a sliding support 2, which is slidably connected to the base guide rail 1. The top of the sliding support 2 is provided with a first through groove 21 for setting the placement component, and the middle area of ​​the sliding support 2 is provided with a second through groove 22. The solid structure of the sliding support 2 between the first through groove 21 and the second through groove 22 forms a crossbeam, and the adjustment component is set on the crossbeam.

[0057] The distance between the two sliding supports 2 can be adjusted by sliding them on the base guide rail 1.

[0058] like Figure 13 and Figure 14 As shown, the placement component includes a support block 3. The two sides of the support block 3 are slidably connected to the lifting grooves on the two inner walls of the first through groove 21, respectively. The top of the support block 3 is recessed downward to form two symmetrically arranged support slopes 31. The two support slopes 31 together form a placement cavity.

[0059] The support block 3 slides inside the lifting grooves on the two inner walls of the first through groove 21, thereby adjusting the height of the support block 3.

[0060] The adjusting component is either the first fixing component 4 or the second fixing component. The first fixing component 4 is a screw rod arranged vertically. The screw rod passes through the crossbeam vertically and is connected to the crossbeam by thread engagement. The top of the screw rod is connected to the bottom side wall of the support block 3.

[0061] The second fixing component includes a support rod 8 arranged vertically, which passes through the crossbeam and is fixedly connected to the bottom side wall of the placement block at its top and slidably connected to the guide sleeve 81 at its bottom. A locking bolt is inserted into the surface of the guide sleeve 81, which passes through the side wall of the guide sleeve 81 and is connected to the side wall of the guide sleeve 81 by thread engagement. The end of the locking bolt can abut against the outer wall of the support rod 8. The guide sleeve 81 is fixed to the inner wall of the second through groove 22 by the rod.

[0062] A buffer spring is fitted at the sliding connection between the support rod 8 and the guide sleeve 81.

[0063] By rotating the screw, the screw is pushed to move vertically through the thread engagement, thereby causing the support block 3 to move up or down.

[0064] By sliding the support rod 8 on the surfaces of the crossbeam and guide sleeve 81, the position of the support rod 8 is changed, causing the support block 3 to move vertically. The position of the support block 3 is fixed by locking the support rod 8 and guide sleeve 81 with locking bolts.

[0065] The limiting component includes a T-block 12 and a fixing bolt 13. The T-block 12 is slidably connected to the inside of the movable slide groove 11 on the base guide rail 1. The fixing bolt 13 passes vertically through the bottom side wall of the second through groove 22 and extends into the threaded hole on the T-block 12. The threaded hole and the fixing bolt 13 are connected by thread engagement.

[0066] Rotate the fixing bolt 13 so that it is fully screwed into the T-block 12, pressing the T-block 12 tightly against the top inner wall of the movable slide groove 11, thereby fixing the position of the sliding support 2 on the base guide rail 1.

[0067] The first clamping assembly 5 includes a plurality of retractable first adjusting rods 52, and the ends of two adjacent first adjusting rods 52 are movably connected by a connecting part 53.

[0068] One end of the two outermost first adjusting rods 52 is fixedly connected to the moving block, the moving block is slidably connected to the adjusting guide rails 51 distributed vertically, the adjusting guide rails 51 are fixed to the outer wall of one of the sliding supports 2, and the other end of the first adjusting rod 52 is connected to the clamping unit 54 that clamps the dial indicator.

[0069] like Figure 7 As shown, the connecting part 53 includes a connecting cover 531 with a spherical structure and a connecting ball 532. The connecting cover 531 covers more than half of the surface area of ​​the connecting ball 532, and the connecting ball 532 rotates inside the connecting cover 531. The ends of two adjacent first adjusting rods 52 are respectively fixedly connected to the connecting cover 531 and the connecting ball 532.

[0070] A damping layer is fixed to the inner wall of the connecting outer cover 531 and adheres to the surface of the connecting ball 532. The first adjusting rod 52 is composed of two rods of different diameters that slide and fit together. A damping layer is also provided on the inner wall of the outer rod. The damping layer is made of a material with a high coefficient of surface friction. Thus, damped motion is formed between the connecting ball 532 and the connecting outer cover 531, and between the two rods of the first adjusting rod 52 sliding together. Without external force interference, the connecting ball 532 does not rotate inside the connecting outer cover 531, and the first adjusting rod 52 does not extend or retract.

[0071] A damping layer is also provided on the inner wall of the adjusting guide rail 51, so that the moving block makes damped movement inside the adjusting guide rail 51.

[0072] The damping layer prevents relative movement of the various active areas of the first clamping component 5 when no external force is applied, so that when the dial indicator is not in use, it will remain in the position placed by the user after the last use.

[0073] The clamping unit 54 includes a mounting frame 541, on which two symmetrically arranged bearing arc plates 542 are fixed. A first sliding rod 544 is slidably inserted into the bearing arc plate 542. A first clamping arc plate 53 is fixed to the end of the first sliding rod 544. A limiting spring is sleeved on the surface of the first sliding rod 544.

[0074] The two ends of the limiting spring are fixed to the first sliding rod 544 and the bearing arc plate 542 respectively, and the dial indicator is clamped between the two first clamping arc plates 53. Through the reaction force of the limiting spring, the first clamping arc plate 53 is pressed tightly against the outer wall of the dial indicator.

[0075] The second clamping assembly 6 includes a mounting part 63, which includes an arc-shaped guide rail 631. A movable strip 632 with the same arc-shaped structure is slidably connected to the inner ring side wall of the arc-shaped guide rail 631. Near the inner ring end of the movable strip 632, it is connected to the placement unit 634 for placing a dial indicator via a telescopic second adjusting rod 633. The second adjusting rod 633 is arranged radially along the arc-shaped guide rail 631 and the movable strip 632.

[0076] The central angles of both the arc-shaped guide rail 631 and the movable strip 632 are greater than 90°, and the notch of the arc-shaped guide rail 631 is preferably set facing upwards;

[0077] The arc-shaped guide rail 631 is slidably connected to the base guide rail 1 via a sliding part.

[0078] The sliding part includes two symmetrically arranged bearing guide rails 61. The two ends of the bearing guide rails 61 are fixed to the base guide rails 1 by vertical rods (not shown in the figure). The bearing guide rails 61 pass through the sliding support 2, that is, the sliding support 2 can slide on the bearing guide rails 61. A bearing slider 62 is slidably connected to the bearing guide rails 61. The bearing slider 62 is connected to the outer wall of the bearing guide rails 61 by rods.

[0079] By utilizing the sliding of the movable strip 632 inside the arc-shaped guide rail 631 and the length of the movable strip 632 itself, the movable strip 632 can move in a circular trajectory on the arc-shaped guide rail 631, thereby making circumferential movement on the rotor surface.

[0080] Meanwhile, the arc-shaped guide rail 631 can move along the bearing guide rail 61, thus enabling the dial indicator to move in different directions.

[0081] The placement unit 634 includes a placement shell 6341, which is connected to the end of the second adjusting rod 633. Two symmetrically arranged second sliding rods 6342 are slidably inserted into the side wall of the placement shell 6341. A second clamping arc plate 6343 is fixed to the end of the second sliding rod 6342, and a limit spring is sleeved on the surface of the second sliding rod 6342.

[0082] The reaction force of the limiting spring causes the two second clamping arc plates 6343 to be clamped and fixed on the dial indicator.

[0083] The sliding connection of the second adjusting rod 633 is provided with a damping layer with the same structure as the sliding connection of the first adjusting rod 52, and damping layers are also provided on the outer wall of the bearing guide rail 61 and the inner wall of the arc-shaped guide rail 631.

[0084] like Figures 12-13 As shown, it also includes a leveling component 7, which includes a bearing plate 71 set on top of the two support components. Guide telescopic rods 72 are fixed at the four corners of the bottom side wall of the bearing plate 71. The bottom of the guide telescopic rods 72 is flush with the bottom side wall of the base guide rail 1 or fixedly connected to the base guide rail 1 through rods. A support spring 73 is sleeved on the surface of the guide telescopic rod 72. The two ends of the support spring 73 are fixedly connected to the two sides of the guide telescopic rod 72 that slide and extend.

[0085] Both sides of the bottom sidewall of the bearing plate 71 are slidably connected with connecting vertical rods 74, and the bottom end of the connecting vertical rods 74 is fixed with a lower pressure plate 75 distributed in the horizontal direction;

[0086] There are two adjusting components, one of which is the first fixing component 4, and the other is the second fixing component.

[0087] Position the two support blocks 3 on the same horizontal line, or close to being on the same horizontal line. Place both ends of the rotor on the two placement cavities respectively, with the side with the larger diameter placed on the support block 3 with the second fixing member. Then slide the connecting vertical rod 74 to the surface of one section of the cylindrical structure of the rotor. Then press down the bearing plate 71, and the lower pressure plate 75 moves down accordingly. Then rotate the locking bolt to disengage it from the surface of the support rod 8. At this time, the rotor is supported by the buffer spring. Then continue to press down the bearing plate 71. The lower pressure plate 75, which moves down synchronously with the bearing plate 71, gradually comes into contact with the top surface of the cylindrical structure of the rotor until the bottom end of the bearing plate 71 is completely in contact with the top surface of the cylindrical structure of the rotor. At this time, the entire rotor is in a horizontal position. Then reverse the locking bolt to fix the support rod 8.

[0088] During the above process, both the buffer spring and the support spring 73 are compressed. When the rotor is in a horizontal position and the locking bolt is tightened again on the support rod 8, the bearing plate 71 is released and returns to its original position under the action of the rebound of the support spring 73.

[0089] It can help solve the measurement of key geometric tolerances such as rotor position and profile.

[0090] After leveling, press the dial indicator needle against the outer circle to be inspected, then manually rotate the rotor part to observe the surface reading changes and record the coaxiality error value; move the needle to different outer circle positions to detect runout data at other positions.

[0091] During measurement, the user can directly hold the clamping unit 54 or the placement unit 634 with the dial indicator. After measurement, the first clamping component 5 and the second clamping component maintain their ability to remain undeformed without external force, so that the dial indicator is suspended in a position that is convenient for the user.

The protection scope of this invention is defined by the appended claims.
