Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor component testing equipment, in particular to a motor rotor testing equipment. Background Art
[0002] The motor is one of the main drivers of modern machinery. Through the motor, the equipment components connected thereto can be driven to rotate. There are many components of the motor, among which the stator and the rotor are the main components. The stator is fixed on the inner wall of the motor housing, and the rotor is installed between the stators and can rotate. Therefore, when the motor is produced, it is necessary to test whether the rotor and the stator are qualified.
[0003] Since an output shaft needs to be connected inside the rotor, its testing method is different from that of the stator. In order to ensure that the rotor can rotate stably and output, it is necessary to ensure that it is a circular structure and there is no eccentricity. At present, there are basically no corresponding testing components, and the eccentricity is judged by the scale on the ruler, and the eccentricity is also likely to cause problems in other testing aspects. Therefore, a motor rotor testing equipment is proposed. Content of the Utility Model
[0004] The technical solution adopted by the utility model to solve the technical problems is: a motor rotor testing equipment, including a workbench. Two adjusting grooves are opened at the top of the workbench and close to the middle position. A follower column is telescopically and movably arranged on the side wall between the two adjusting grooves at the top of the workbench. One end of the follower column away from the workbench is fixedly connected with a pressure receiving plate. The pressure receiving plate is of an arc structure. Above each of the two adjusting grooves, a moving block is arranged. Each moving block is telescopically connected with an adjusting block. At the middle side of the relative and top parts of the two adjusting blocks, a connecting head is rotatably connected. One side wall of the adjusting block away from the connecting head is detachably connected with a driver. The output end of the driver passes through the adjusting block and is detachably connected to one side wall of the end of the connecting head.
[0005] As a preferred technical solution of the utility model, a bottom groove is opened inside the connecting head. Two lifting rods are detachably connected to the bottom side wall inside the bottom groove. The output ends of the lifting rods are detachably connected to the bottom side wall of the adjusting block. A clamp tightened by a stud is connected inside the connecting head.
[0006] As a preferred technical solution of the utility model, an activity groove is opened inside the workbench between the two adjusting grooves. Roller shafts are evenly rotatably connected to the top side wall of the pressure receiving plate. A through hole is opened through the middle of a section of the follower column located inside the activity groove of the workbench, and a spring is fixedly connected to the middle of the bottom side wall of one end of the follower column located inside the activity groove.
[0007] As a preferred technical solution of the present utility model, an electrode plate is inlaid and connected to the bottom side wall of the follower column, and an opening is formed through the middle of the electrode plate. Two warning lights are arranged directly below the electrode plate. The warning lights and the springs are detachably connected to the bottom side wall of the movable groove through the bottom ends. An observation port is formed in the middle of one side wall of the workbench, and the observation port communicates with the movable groove.
[0008] As a preferred technical solution of the present utility model, a screw rod is rotatably connected in the adjustment groove. The screw rod is of a double-thread structure. The screw rod passes through the through hole and rotates in two adjustment grooves at the same time. Sliding blocks are threadedly sleeved at both ends of the screw rod, and the sliding blocks are detachably connected to the bottom side wall of the moving block. One end side wall of the workbench is detachably connected with a knob, and the knob is detachably connected with one end of the screw rod.
[0009] The present utility model has the following advantages: Connect the rotor between two adjustment blocks, and at the same time place and fit the coil part on the top side wall of the pressure receiving plate. Then drive the rotor to rotate through the driver. If the coil part on the rotor is installed obliquely, pressure will be exerted on the pressure receiving plate and the follower column during rotation. When the follower column is subjected to pressure, it will push downwards and finally connect the wiring point of the electrode plate and the warning light, and then the warning light will light up, and the light will emit from the observation port. In this way, it can be directly understood that the rotor coil is skewed, improving the convenience of detection side view. Because it only needs to be rotated once to know whether it is skewed without repeated measurement, it can effectively improve the side view efficiency and reduce the defective product rate.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] The present utility model will be further described below with reference to the drawings.
[0015] Please refer to Figures 1 - 3, a motor rotor testing device of the present utility model includes a workbench 1. Two adjustment slots 2 are opened at the top of the workbench 1 near the middle position. A follower column 8 is telescopically and movably arranged on the side wall between the two adjustment slots 2 at the top of the workbench 1. One end of the follower column 8 away from the workbench 1 is fixedly connected to a pressure receiving plate 9. The pressure receiving plate 9 is of an arc-shaped structure. Above each of the two adjustment slots 2, a moving block 4 is arranged. Each moving block 4 is telescopically connected with an adjustment block 5. At the middle side near the top and opposite to each other of the two adjustment blocks 5, a connecting head 6 is rotatably connected. One side wall of one of the adjustment blocks 5 away from the connecting head 6 is detachably connected with a driver 7. The output end of the driver 7 passes through the adjustment block 5 and is detachably connected to one side wall of the connecting head 6;
[0016] An activity slot is opened inside the workbench 1 between the two adjustment slots 2. Roller shafts 14 are evenly rotatably connected to the top side wall of the pressure receiving plate 9. A through hole 15 is opened through the middle of a section of the follower column 8 located inside the activity slot of the workbench 1. And a spring 16 is fixedly connected to the middle of the bottom side wall of one end of the follower column 8 located inside the activity slot. An electrode piece 17 is inlaid and connected to the bottom side wall of the follower column 8. And an opening is opened through the middle of the electrode piece 17. Two warning lights 18 are arranged directly below the electrode piece 17. The warning lights 18 and the spring 16 are detachably connected to the bottom side wall of the activity slot through their bottom ends. An observation port 10 is opened at the middle of one side wall of the workbench 1. And the observation port 10 communicates with the activity slot.
[0017] The technical effect of this solution is as follows: Place the rotor to be side-viewed between the two connecting heads 6. After placing it stably, start the driver 7 to drive the connecting head 6 to rotate and drive the rotor to rotate synchronously. After the rotor is placed, the coil part on it will fit on the side wall of the pressure receiving plate 9. If the coil part of the rotor is of a perfect circular structure, then the pressure receiving plate 9 and the follower column 8 will not change their positions when the rotor rotates. If there is a problem of deviation, then pressure will be exerted on the pressure receiving plate 9 and the follower column 8 during rotation. And the follower column 8 will contract downward under the force, so that the connection between the electrode piece 17 and the warning light 18 will be fitted, and thus the warning light 18 will emit light, and the light will escape from the observation port 10, which is convenient for the staff to observe and improves the detection efficiency and accuracy.
[0018] A screw rod 3 is rotatably connected inside the adjustment slot 2. The screw rod 3 is of a double-threaded structure. The screw rod 3 passes through the through hole 15 and rotates inside the two adjustment slots 2 at the same time. Threaded sleeves are sleeved on both ends of the screw rod 3, and the sliders are detachably connected to the bottom side wall of the moving block 4. One end side wall of the workbench 1 is detachably connected with a knob 11. The knob 11 is detachably connected to one end of the screw rod 3. A bottom slot 12 is opened inside the connecting head 6. Two lifting rods 13 are detachably connected to the bottom side wall of the bottom of the bottom slot 12. The output ends of the lifting rods 13 are detachably connected to the bottom side wall of the adjustment block 5. A clamp tightened by a stud is connected inside the connecting head 6.
[0019] The technical effects of this solution are as follows: By connecting two lifting rods 13 in the bottom groove 12, when needed, the lifting rods 13 are activated to drive the adjusting block 5 to perform telescopic activities in the bottom groove 12, thereby adjusting the height position of the connecting head 6. At the same time, the distance between the two adjusting blocks 5 can be adjusted by the provided screw rod 3. The two cooperate to be able to test rotors of different sizes, improving the convenience and flexibility of application.
[0020] Specifically, when the present utility model is in use, both ends of the rotor to be tested are connected in the corresponding connecting heads 6, and then it is positioned by the built-in fixture, and it is observed whether the rotor coil part is in contact with the pressure receiving plate 9. After confirmation, the driver 7 is activated to drive the rotor to rotate. If there is any deflection during rotation, pressure will be exerted on the pressure receiving plate 9 and the follower post 8. When the follower post 8 is pressed, it will retract downward, which will drive the electrode plate 17 to be in contact with the warning lamp 18. In this way, the warning lamp 18 will be powered on and emit light, and the light will be emitted from the observation port 10 for the convenience of the staff to observe. In this way, it is not necessary to use a ruler for repeated measurements, which can effectively improve the test efficiency and the accuracy of the results. According to the situation, a battery can be built into the follower post 8 as a power source or an external power source can be used through wires.
[0021] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
[0022] Other parts not detailed in the present utility model belong to the prior art, so they will not be elaborated here.
[0023] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
