Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically a rotor measuring device. Background Technology

[0002] The elevator traction machine is the power equipment of the elevator, also known as the elevator main unit. Its function is to deliver and transmit power to make the elevator run. It consists of a motor, brake, coupling, gearbox, traction sheave, frame, guide wheel, and auxiliary handwheel. The rotor is the core rotating component in the traction machine motor or rotating machinery. It is usually composed of an iron core, windings, and shaft. It is used to realize the conversion of electrical energy and mechanical energy. According to ISO standards, any rotating body supported by bearings can be called a rotor. The rotor cuts magnetic field lines in the rotating magnetic field generated by the stator, generating induced current or is directly acted upon by a permanent magnetic field, thereby generating electromagnetic torque to drive rotation.

[0003] For example, the generator rotor measuring device disclosed in the authorization announcement number CN221404254U includes: a base, a plurality of evenly distributed support plates fixedly installed on the top of the base, a fixed plate fixedly installed on the top of the support plates, a plurality of evenly distributed opening slots opened on the top of the fixed plate, a placement seat fixedly installed in the middle of the top of the fixed plate, a rotor assembly and a rotor limiting component provided on the upper part of the placement seat, and the rotor limiting component is located at the top of the base; Although it achieves the goal of converging the constraint plate towards the rotor assembly when the cylinder drives the movable plate to move downward, the first connecting rod, in conjunction with the second connecting rod, the support plate, and the support lug, and the constraint plate installed at the end of the first connecting rod, the constraint plate, in conjunction with the constraint groove, can fix rotor assemblies of different sizes and specifications, avoiding instability of the rotor assembly during the testing process, which would affect the testing accuracy of the rotor assembly; However, this does not solve the problem that existing measuring devices of this type are generally not conducive to the convenient multi-stage linkage of the measuring device for rapid center positioning and clamping of the rotor, nor to the center positioning and clamping of rotors of different diameters. This affects the convenience of the multi-stage linkage of the measuring device for rapid center positioning and clamping of the rotor, and is not conducive to the multi-stage movement of the measuring device for rotor detection, thus affecting the efficiency of the multi-stage movement of the measuring device for rotor detection.

[0014] Preferably, a grating reading head is mounted on the surface of the probe inside the sleeve, and a scale grating is mounted on the inner wall of the sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the measuring device not only realizes the convenient multi-stage linkage of the measuring device for rapid center positioning and clamping of the rotor, facilitating the center positioning and clamping of rotors of different diameters and improving the convenience of the multi-stage linkage of the measuring device for rapid center positioning and clamping of the rotor, but also realizes the multi-stage moving position of the measuring device for rotor detection, improving the efficiency of the multi-stage moving position of the measuring device for rotor detection.

[0022] Example 1 Please see Figure 1-8 This utility model provides an embodiment of a rotor measuring device, comprising a transverse lead screw moving assembly 1 and a longitudinal lead screw moving assembly 2. The longitudinal lead screw moving assembly 2 is mounted on the top of the transverse lead screw moving assembly 1. A rotor body 3 is disposed outside the longitudinal lead screw moving assembly 2.

The threaded blocks 8 are connected to the moving plates 5. Stepper motors 9 are mounted on the side walls of a set of moving plates 5. Rotary shafts are mounted on the output ends of the stepper motors 9. 10. A rotating shaft 10 extends through a set of movable plates 5 to its outside. A set of support frames 11 is installed at the end of the rotating shaft 10 away from the stepper motor 9. Another set of support frames 11 is movably installed on the side wall of another set of movable plates 5. A power motor 12 is installed inside each support frame 11. A worm gear 13 is installed at the output end of each power motor 12. A rotating frame 14 is installed on the side wall of each support frame 11. The worm gear 13 extends into the interior of the rotating frame 14 and is movably connected to it. Four sets of first shafts 16 are movably installed on the surface of each rotating frame 14. The first shafts 16 extend through the rotating frame 14 to its outside. A worm wheel 15 is fitted on the surface of each first shaft 16 outside the rotating frame 14. The worm wheel 15 extends into the interior of the rotating frame 14 and meshes with the worm gear 13.

[0023] The surface of the first shaft 16 outside the worm gear 15 is fitted with a first support arm 17, which is fixedly connected to the worm gear 15. A second shaft 18 is movably installed on the side of the first support arm 17 away from the first shaft 16.

The third shaft 20 is movably connected to the second support arm 19. The bottom end of the second support arm 19 is fitted with an arc-shaped clamp 23.

[0025] When using the rotor measuring device, the rotor body 3 is manually placed in the working area. Two sets of servo motors 6 are turned on. Supported by the moving platform 4, the servo motors 6 drive the threaded rod 7 to rotate. With the threaded connection between the threaded rod 7 and the threaded block 8, the threaded rod 7 drives the threaded block 8 and the moving plate 5 to move in opposite directions, causing the two sets of clamping tools to move to both ends of the rotor. Two sets of power motors 12 are then turned on. Supported by the support frame 11, the power motors 12 drive the worm gear 13 to rotate. With the meshing of the worm gear 13 and the worm wheel 15, the worm gear 13 drives the four sets of worm wheels 15 to rotate. Under the movable support of the first shaft 16, the worm wheels 15 drive the first support arm 17 to rotate synchronously. The first support arm 17, via the second shaft 18, drives the second support arm 19 to rotate. The fourth shaft 21... The third support arm 22 provides limiting support, and the third support arm 22 provides limiting support to the second support arm 19 via the third shaft 20. The second support arm 19 drives the arc-shaped clamping plate 23 to move, so that multiple sets of arc-shaped clamping plates 23 can quickly and stably center-position and clamp the two ends of the rotor. The stepper motor 9 is turned on, and under the support of the moving plate 5, the stepper motor 9 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the support frame 11, the first support arm 17, the second support arm 19, the third support arm 22, the arc-shaped clamping plate 23, and the rotor to rotate. This realizes the convenient multi-stage linkage of the measuring device to quickly center-position and clamp the rotor, which is convenient for center-positioning and clamping rotors of different diameters and improves the convenience of the multi-stage linkage of the measuring device to quickly center-position and clamp the rotor.

[0026] A support plate 24 is installed at the output end of the longitudinal lead screw moving assembly 2, a cylinder 25 is installed at the top of the support plate 24, an L-shaped frame 26 is installed at the output end of the cylinder 25, and a sleeve 27 is installed at the top of the L-shaped frame 26.

[0027] A spring 29 is installed inside the sleeve 27. A connecting plate 32 is installed at the end of the spring 29 away from the sleeve 27. A probe 28 is installed on the side wall of the connecting plate 32. The probe 28 extends to the outside of the sleeve 27 and is slidably connected to it.

[0028] An optical grating reading head 31 is mounted on the surface of the probe 28 inside the sleeve 27, and a scale grating 30 is mounted on the inner wall of the sleeve 27.

[0029] When it is necessary to measure the rotor, the transverse lead screw moving assembly 1 and the longitudinal lead screw moving assembly 2 are moved so that the probe 28 moves to the surface of the rotor. The cylinder 25 is opened, and under the support of the support plate 24, the cylinder 25 drives the L-shaped frame 26, the sleeve 27, and the probe 28 to move, so that the probe 28 comes into contact with the rotor. Since the sleeve 27 is equipped with a spring 29, the probe 28 slides inside the sleeve 27 through the spring 29, so that the probe 28 makes elastic contact with the rotor body 3, and the probe 28 measures the surface of the rotor body 3. The probe 28 drives the grating reading head 31 to move synchronously. The grating reading head 31 slides on the surface of the scale grating 30. At this time, the grating reading head 31 and the scale grating 30 transmit data to the external controller through wires. The external Internet computer analyzes and processes the data. When the sliding range of the grating reading head 31 on the surface of the scale grating 30 is too large, it is marked as unqualified. At this time, the external operator will handle the problem. This realizes the multi-level movement position of the measuring device to detect the rotor, which improves the efficiency of the multi-level movement position of the measuring device to detect the rotor.

[0030] Work steps When using the rotor measuring device, the rotor body 3 is manually placed in the working area. The servo motor 6 drives the threaded rod 7 to rotate. The threaded rod 7 drives the threaded block 8 and the moving plate 5 to move in opposite directions, so that the two sets of clamping tools move to both ends of the rotor. The power motor 12 drives the worm gear 13 to rotate. The worm gear 13 drives the four sets of worm wheels 15 to rotate. The worm wheels 15 drive the first shaft 16, the first support arm 17, the second shaft 18, and the second support arm 19 to rotate. Under the limiting support of the fourth shaft 21, the second support arm 19 drives the third shaft 20, the third support arm 22, and the arc-shaped clamping plate 23 to rotate a certain angle around the fourth shaft 21, so that the multiple sets of arc-shaped clamping plates 23 quickly and stably clamp the two ends of the rotor. Motor 9 drives rotating shaft 10 to rotate, which in turn drives support frame 11, first support arm 17, second support arm 19, third support arm 22, arc-shaped clamp 23, and rotor to rotate. When it is necessary to measure the rotor, the transverse lead screw moving assembly 1 and the longitudinal lead screw moving assembly 2 are moved so that probe 28 moves to the surface of the rotor. Cylinder 25 drives L-shaped frame 26, sleeve 27, and probe 28 to move so that probe 28 contacts the rotor. Since spring 29 is installed inside sleeve 27, probe 28 slides inside sleeve 27 through spring 29, so that probe 28 makes elastic contact with rotor body 3. Probe 28 measures the surface of rotor body 3 to complete the use of the measuring device.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
