Description

[0002] A motor rotor runout detection device is a device used to detect the circular runout of a motor rotor. It is generally divided into contact rotor runout detection devices that use mechanical sensors such as dial indicators and micrometers, and non-contact rotor runout detection devices that use laser displacement sensors or photoelectric encoders.

[0003] Most existing motor rotor runout detection devices are single-point, resulting in low detection efficiency and a time-consuming detection process. Contact-type rotor runout detection equipment is prone to wear and tear during long-term use, which affects the accuracy of the equipment. Non-contact rotor runout detection equipment has high environmental requirements, and the detection process is easily affected by the environment, leading to errors in the detection process.

[0008] Furthermore, a limiting slider is provided at the connection position between the scissor lift and the limiting support plate and the T-shaped limiting plate. The limiting slider is respectively connected through to the middle of the corresponding scissor lift and one end of the corresponding limiting support plate. A limiting cavity is formed on the T-shaped limiting plate. One end of the limiting slider is connected through to the limiting cavity, and the limiting slider is slidably connected to the limiting cavity. A fixing nut is rotatably connected at the connection position between the fixing post and the detection ring.

[0009] Furthermore, one end of the push-pull support plate is rotatably connected to a hydraulic telescopic rod, and one end of the hydraulic telescopic rod is rotatably connected to a fixed plate via a hinge rod.

[0010] Furthermore, a clamping mechanism is installed on the support plate. The clamping mechanism includes a lower clamping plate and an upper clamping plate located at one end of the support plate. A lifting slider is fixedly connected to one end of each of the upper and lower clamping plates. A push-adjusting block is fixedly connected to the middle of the lifting slider. A lifting cavity is opened in the middle of the support plate. The upper and lower clamping plates are slidably connected to the support plate through the lifting slider and the lifting cavity. An adjusting shaft is provided at the other end of the support plate. A set of adjusting arc grooves are symmetrically opened on the adjusting shaft. The push-adjusting blocks at one end of the upper and lower clamping plates are slidably connected to one of the corresponding adjusting arc grooves in the set of adjusting arc grooves. A support plate and a fixed platform are fixed on the support plate.

[0011] Furthermore, the adjusting shaft is located within the gap between the support plate and the fixed platform. One end of the adjusting shaft is connected through the support plate, and the other end of the adjusting shaft is rotatably connected to the fixed platform. A first motor is provided on the support plate, and the output end of the first motor is fixedly connected to the end of the adjusting shaft that passes through the support plate.

[0012] Furthermore, a clamping disc is rotatably connected to both the upper and lower clamping plates. A positioning ring cavity is formed in the middle of the upper and lower clamping plates. A clamping cavity is formed inside the clamping disc. The positioning ring cavity communicates with the clamping cavity.

[0015] Furthermore, a base plate is fixedly connected to the other end of the fixed platform, and a data display screen is mounted on the base plate.

[0016] The beneficial effects of this application are: it facilitates the adjustment of the size of the rotor clamping cavity as needed, facilitates the quick clamping and fixing of the clamping cavity, facilitates multi-point mixed detection of the rotor, helps to improve the accuracy of motor rotor concentricity runout detection, and the combination of contact mechanical sensing detection and non-contact photoelectric detection helps to improve the effect of motor rotor runout detection.

[0017] This application provides a motor rotor runout detection device. Through a runout detection mechanism, when the motor rotor rotates, the resulting runout pushes a pressure sensor inwards towards a fixed column. During this contraction, a mechanical structure within a dial indicator converts the minute linear displacement of the probe into the rotational motion of a pointer within the dial indicator. By observing the changes in multiple dial indicators mounted on multiple detection rings, the device determines the runout at multiple points during the motor rotor's rotation. Simultaneously, multiple laser diodes within multiple optical path emitters synchronously emit light beams towards the motor rotor. After reflection and obstruction by the motor rotor, the light beams illuminate multiple optical path receivers. Multiple photodiodes within these receivers capture the corresponding light signals, thereby capturing the periodic displacement fluctuations during rotor rotation. The two detection methods work together to improve the detection effect of the motor rotor, facilitating multi-point mixed detection of the rotor and improving the accuracy of motor rotor concentricity runout detection. The combination of contact-type mechanical sensing detection and non-contact photoelectric detection enhances the effectiveness of motor rotor runout detection.

[0018] This application provides a motor rotor runout detection device. Through a clamping mechanism, one end of the motor rotor is clamped onto a lower clamping plate. This allows one end of the motor rotor to pass through a positioning ring cavity and be clamped into a clamping cavity within a rotatably connected clamping disc on the lower clamping plate. The clamping cavity within the clamping disc supports the motor rotor. With manual assistance, the motor rotor is held in place. Simultaneously, a first motor drives an adjusting shaft fixedly connected to its output end to rotate. This rotation of the adjusting shaft causes a set of adjusting arc grooves on it to rotate synchronously. The changing angle of these adjusting arc grooves is controlled by their internal connections. A set of push-adjusting blocks drives a set of lifting sliders fixedly connected to the push-adjusting blocks to slide relative to each other along the lifting cavity opened on the support plate. The relative sliding of the lifting sliders will drive the upper clamping plate and the lower clamping plate connected at one end to slide relative to each other synchronously. When the clamping plate connected to the upper clamping plate gets stuck at the other end of the rotor during the sliding process, the clamping force generated by the clamping plate connected to the upper clamping plate and the lower clamping plate respectively will clamp and position the rotor between them. This facilitates the adjustment of the size of the rotor clamping cavity as needed and facilitates the quick clamping and fixing of the clamping cavity.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] like Figure 1-7As shown, this application provides a motor rotor runout detection device, including a support plate 3. One end of the support plate 3 is provided with a runout detection mechanism 6. The runout detection mechanism 6 includes a set of T-shaped limiting plates 61. Multiple scissor lifters 64 connected by hinge blocks are slidably connected to the set of T-shaped limiting plates 61. One end of each set of T-shaped limiting plates 61 is fixedly connected to a fixed frame 615 by a nut. A scissor lifter 64 located near the fixed frame 615 on the set of T-shaped limiting plates 61 is rotatably connected to a push-pull support plate 62 by a hinge block. The last scissor lifter 64, located away from the fixed frame 615, is rotatably connected to a limit plate 65 via a hinge block. Multiple detection rings 68 are equidistantly distributed in the middle of a set of T-shaped limit plates 61. Each detection ring 68 is fixedly connected to a light transmitter 67 and a light receiver 616, which are symmetrically distributed on the detection rings 68. A fixed post 611 passes through the middle of one end of each detection ring 68, and a pressure sensor 612 passes through the fixed post 611. The pressure sensor 612 slides and extends with respect to the fixed post 611. A dial indicator 613 is fixedly connected to the fixed post 611. A limiting slider 66 is provided at the connection points of the scissor lift 64 and the limiting support plate 65 with the T-shaped limiting plate 61. The limiting slider 66 is respectively connected through to the middle of the corresponding scissor lift 64 and one end of the corresponding limiting support plate 65. A limiting cavity 63 is formed on the T-shaped limiting plate 61, and one end of the limiting slider 66 is connected through to the limiting cavity 63, and the limiting slider 66 is slidably connected to the limiting cavity 63. A fixing nut 618 is rotatably connected at the connection point between the fixed post 611 and the detection ring 68. One end of the support plate 62 is rotatably connected to a hydraulic telescopic rod 69, and one end of the hydraulic telescopic rod 69 is rotatably connected to a fixed plate 614 via a hinge rod. One end of the fixed frame 615 is fixedly connected to the lower clamping plate 48. A set of T-shaped limiting plates 61 are symmetrically distributed at both ends of the lower clamping plate 48. A beam receiving port 617 is provided at the connection position between the optical path receiver 616 and the detection ring 68. A beam emitting port is provided at the connection position between the optical path transmitter 67 and the detection ring 68. The other end of the fixed platform 2 is fixedly connected to a base plate 1, and a data display screen 610 is installed on the base plate 1.

[0033] In this embodiment, during detection, the hydraulic telescopic rod 69 pushes a push-pull support plate 62, which is rotatably connected at one end, to rotate around the axis point connected to the T-shaped limiting plate 61 at a specified angle. When the push-pull support plate 62 rotates, it drives multiple scissor lifters 64 connected at the other end to simultaneously generate scissor lift motion, thereby driving the limiting support plate 65 connected at one end of the scissor lifter 64 to synchronously generate scissor lift motion. The scissor lifters 64 and the limiting support plate 65 generating scissor lift motion will drive multiple detection rings 68, which are fixedly connected at one end of the multiple limiting sliders 66, to synchronously generate lifting and lowering motion through multiple limiting sliders 66 connected through them. This causes the multiple detection rings 68 to be evenly distributed on the motor. On the outside of the rotor, multiple optical transmitters 67, multiple optical receivers 616, multiple pressure sensors 612, multiple fixed columns 611, and multiple dial gauges 613, which are installed on multiple detection rings 68, are moved synchronously to the designated positions on the motor rotor and are evenly distributed on the motor rotor. When the scissor lifter 64 and the limiting support plate 65 generate scissor lift motion, one end of the multiple limiting sliders 66 that are connected through the upper part will slide along the limiting cavity groove 63 opened on the T-shaped limiting plate 61, thereby improving the stability of the scissor lifter 64 and the limiting support plate 65 scissor lift motion and preventing the scissor lifter 64 and the limiting support plate 65 from shifting their positions during the motion.

[0034] During testing, when the motor rotor rotates, the resulting vibration pushes the pressure sensor 612 into the fixed column 611. During this contraction, the small linear displacement of the probe is converted into the rotational motion of the pointer within the dial indicator 613 by a mechanical structure. By observing the changes of the multiple dial indicators 613 installed on the multiple detection rings 68, the vibration at multiple points during the rotation of the motor rotor can be determined. Simultaneously, multiple laser diodes within multiple optical transmitters 67 synchronously emit light beams towards the direction of the motor rotor. After reflection and obstruction by the motor rotor, the light beams illuminate multiple optical receivers 616. Multiple photodiodes within the optical receivers 616 capture the corresponding light signals, thereby capturing the periodic displacement fluctuations during rotor rotation. The two detection methods work together to improve the detection effect of the motor rotor. The detected data is displayed on the data display screen 610 for observation.

[0035] It should be noted that one end of the fixing plate 614 is fixedly connected to the fixing plate fixed on the protective box 410. There are two in a set. The pressure sensor 612 is fixed with a rack structure at the position inside the dial indicator 613. The pointer on the dial indicator 613 is fixed with a gear structure. The rack can convert the linear motion of the pressure sensor 612 into rotational motion by driving the gear.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 and Figure 7 As shown, a clamping mechanism 4 is installed on the support plate 3. The clamping mechanism 4 includes a lower clamping plate 48 and an upper clamping plate 47 located at one end of the support plate 3. A lifting slider 44 is fixedly connected to one end of both the upper clamping plate 47 and the lower clamping plate 48. A push-adjusting block 43 is fixedly connected to the middle of the lifting slider 44. A lifting cavity 45 is opened in the middle of the support plate 3. The upper clamping plate 47 and the lower clamping plate 48 are slidably connected to the support plate 3 through the lifting slider 44 and the lifting cavity 45. An adjusting shaft 41 is provided at the other end of the support plate 3. A set of adjusting arc grooves 42 are symmetrically opened on the adjusting shaft 41. The push-adjusting blocks 43 at one end of the upper clamping plate 47 and the lower clamping plate 48 are slidably connected to one of the corresponding adjusting arc grooves 42 in the set of adjusting arc grooves 42. A support plate 5 and a fixed platform 2 are fixed on the support plate 3. The adjusting shaft 41 is located between the support plate 5 and the fixed platform 2. Within the distance between the fixed platforms 2, one end of the adjusting shaft 41 is connected through the support plate 5, and the other end of the adjusting shaft 41 is rotatably connected to the fixed platform 2. The support plate 5 is equipped with a first motor 46, and the output end of the first motor 46 is fixedly connected to the end of the adjusting shaft 41 that passes through the support plate 5. A clamping plate 49 is rotatably connected to both the upper clamping plate 47 and the lower clamping plate 48. A positioning ring cavity 411 is opened in the middle of the upper clamping plate 47 and the lower clamping plate 48. A clamping cavity 412 is opened in the clamping plate 49. The positioning ring cavity 411 and the clamping cavity 412 are connected. A second motor 413 is fixed to one end of the clamping plate 49 that is rotatably connected to the lower clamping plate 48. A protective box 410 is clamped to the outside of the second motor 413. Fixed plates are provided at both ends of the protective box 410. The protective box 410 is fixedly connected to the lower clamping plate 48 through the fixed plates.

[0037] In this embodiment, one end of the motor rotor is clamped onto the lower clamping plate 48, so that one end of the motor rotor passes through the positioning ring cavity 411 and is clamped into the clamping cavity 412 opened in the clamping plate 49 rotatably connected to the lower clamping plate 48. The clamping cavity 412 opened in the clamping plate 49 supports the motor rotor. The motor rotor is manually supported. At this time, the first motor 46 drives the adjusting shaft 41 fixedly connected to the output end to rotate. The rotating adjusting shaft 41 will drive a set of adjusting arc grooves 42 opened on it to rotate synchronously. The set of adjusting arc grooves 42 that rotate and change angle will drive a set of lifting sliders 44 fixedly connected to the set of pushing adjustment blocks 43 through the set of pushing adjustment blocks 43 to slide relative to each other along the lifting cavity 45 opened on the support plate 3. The set of lifting sliders 44 that slide relative to each other slides relative to each other. The lowering slider 44 will drive the upper clamping plate 47 and the lower clamping plate 48 connected at one end to slide relative to each other synchronously. When the clamping plate 49 rotatably connected to the upper clamping plate 47 is stuck at the other end of the rotor during the sliding process, the clamping force generated by the clamping plate 49 rotatably connected to the upper clamping plate 47 and the lower clamping plate 48 will clamp and position the rotor between them. After the motor rotor is clamped and positioned, the second motor 413 drives the clamping plate 49 fixedly connected to the output end to rotate. The rotating clamping plate 49 will drive the motor rotor clamped and positioned in the clamping cavity 412 through the clamping cavity 412 provided therein to rotate. The rotating motor rotor will rotate at a specified angle under the restriction of the clamping plate 49 rotatably connected to the upper clamping plate 47. At this time, the motor rotor can be detected.

[0038] Working principle:

[0039] One end of the motor rotor is clamped onto the lower clamping plate 48, so that one end of the motor rotor passes through the positioning ring cavity 411 and is clamped into the clamping cavity 412 opened in the clamping plate 49 rotatably connected to the lower clamping plate 48. The clamping cavity 412 opened in the clamping plate 49 supports the motor rotor. The motor rotor is manually supported. At this time, the first motor 46 drives the adjusting shaft 41 fixedly connected to the output end to rotate. The rotating adjusting shaft 41 will drive a set of adjusting arc grooves 42 opened on it to rotate synchronously. The rotation angle changes. A set of adjusting arc grooves 42 will drive a set of lifting sliders 44 fixedly connected to the set of adjusting columns 43 to slide relative to each other along the lifting cavity 45 opened on the support plate 3. The relative sliding of the set of lifting sliders 44 will drive the upper clamping plate 47 and the lower clamping plate 48 connected at one end to slide relative to each other synchronously. When the clamping plate 49 rotatably connected to the upper clamping plate 47 clamps the other end of the rotor during the sliding process, a clamping plate 49 rotatably connected to the upper clamping plate 47 and the lower clamping plate 48 respectively... The clamping force generated by the clamping plate 49 clamps and positions the rotor. After the motor rotor is clamped and positioned, the hydraulic telescopic rod 69 pushes the push-pull support plate 62, which is rotatably connected at one end, to rotate around the axis point connected to the T-shaped limit plate 61 at a specified angle. When the push-pull support plate 62 rotates, it will drive multiple scissor lifters 64 connected at the other end to generate scissor lift motion simultaneously. This will drive the limit support plate 65 connected at one end of the scissor lifter 64 to generate scissor lift motion synchronously. The scissor lifters 64 and the limit support plate 65 generating scissor lift motion will drive multiple detection rings 68, which are fixedly connected at one end of the multiple limit sliders 66, to generate lifting and lowering motion synchronously. This will drive the multiple detection rings 68 to be evenly distributed on the outside of the motor rotor, so that the multiple optical transmitters 67, multiple optical receivers 616, multiple pressure sensors 612, multiple fixed columns 611 and multiple dial gauges 613 installed on the multiple detection rings 68 will move synchronously to the specified position on the motor rotor and be evenly distributed on the motor rotor.

[0040] The second motor 413 drives the clamping plate 49, which is fixedly connected to the output end, to rotate. The rotating clamping plate 49 drives the motor rotor, which is positioned by clamping, to rotate through the clamping cavity 412 inside the clamping plate 412. The rotating motor rotor rotates at a specified angle under the constraint of the clamping plate 49, which is rotatably connected to the upper clamping plate 47. When the motor rotor rotates, the resulting jump pushes the pressure sensor 612 into the fixed column 611. During the contraction process, the small linear displacement of the probe is converted into the rotation of the pointer inside the dial indicator 613 by the mechanical structure inside the dial indicator 613. By observing multiple detections... The changes in the dial gauges 613 installed on ring 68 determine the multiple jumps that occur in the motor rotor during rotation. At the same time, multiple laser diodes installed in multiple optical transmitters 67 synchronously emit light beams in the direction of the motor rotor. After being reflected and blocked by the motor rotor, the light beams illuminate multiple optical receivers 616. Multiple photodiodes installed in multiple optical receivers 616 capture the corresponding light signals, thereby capturing the periodic displacement fluctuations during rotor rotation. The two detection methods work together to improve the detection effect of the motor rotor. The detected data will be displayed on the data display screen 610 for observation.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
