Description

Technical Field

[0001] The utility model relates to a motor rotor detection tool. Background Art

[0002] A motor is an electromagnetic device that realizes electrical energy conversion or transmission based on the law of electromagnetic induction. It can be divided into DC motors and AC motors according to the type of working power supply. DC motors are also composed of rotors and stators, but unlike AC motors, DC motors have coil modules on their rotor cores. Because of the coil modules and other accessories on the rotor, its dynamic balance will be affected. The most important manifestation is vibration during rotation. Long-term vibration of the rotor will accelerate the wear of components such as bearings and shaft seals, thereby reducing the service life and efficiency of the motor. Therefore, when manufacturing and repairing the rotor, the rotor must be dynamically balanced. In addition, since the rotor is wound with a coil module, the coil must be wired to connect each winding after winding, and the wiring must be checked for correctness after wiring.

[0003] At present, the steps of dynamic balancing test and wiring inspection for the rotor are separated and carried out in different testing equipment in sequence, so the rotor must flow between two different testing equipment, and the testing process is quite cumbersome; and because the existing dynamic balancing test equipment and wiring inspection equipment must manually install the rotor into the matching fixture on the corresponding equipment, and the rotor must be manually removed after the inspection is completed, this results in the need to repeatedly install and remove the rotor, which is time-consuming and laborious, and also leads to low work efficiency, which needs further improvement.

[0041] Working principle:

[0042] Start the conveying motor 47 to rotate its rotating shaft, and then drive one of the conveying shafts 44 to rotate with the help of the synchronous belt 49 and the two pulleys 48, and then drive the other conveying shaft 44 to rotate with the help of the conveyor belt 46 and the two conveyor wheels 45 in each feeding combination, so that the conveyor belt 46 in each feeding combination starts to run, and then drive each feeding block 410 to follow each conveyor belt 46 to run in the direction of the dynamic balancing tester 2; put the motor rotor 8 one by one into each feeding block 410 located above the frame 42, and embed the lower end of the motor rotor 8 into the positioning sink cavity 4101, and at the same time, embed the arc-shaped pressing plate at the lower end of the motor rotor 8 into the arched notch groove 4102 to prevent the motor rotor 8 from rotating.

[0043] When the motor rotor 8 moves to the end closest to the dynamic balancing tester 2, the moving end of the first pneumatic slide 33 in the material moving assembly 3 is driven to move to the right to drive the two first double-headed cylinders 35 to move to the right with the help of the first lifting cylinder 34 until the two clamping blocks 6 on the first double-headed cylinder 35 are both located above the above-mentioned motor rotor 8, and then the telescopic end of the first lifting cylinder 34 is driven to extend outward to drive the first double-headed cylinder 35 to move downward, and at the same time, the two telescopic ends of the first double-headed cylinder 35 are driven to extend outward until the two clamping blocks 6 on the first double-headed cylinder 35 are respectively located on the left and right sides of the above-mentioned motor rotor 8, and then the two telescopic ends of the first double-headed cylinder 35 are driven to retract inward to clamp the above-mentioned motor rotor 8 with the help of the arc grooves 61 on the two clamping blocks 6.

[0044] Next, the telescopic end of the first lifting cylinder 34 is driven to retract inward to drive the motor rotor 8 to move upward to leave the feeding block 410, and then the moving end of the first pneumatic slide 33 is driven to move to the left, until the motor rotor 8 moves to the top of the test shaft 22; in this process, it is also necessary to start the power module to drive the test shaft 22 to rotate a certain angle, so that the triangular groove 223 on the dividing plate 222 is rotated to the inner side of the triangular block 76 in the position calibration component 7, and then the telescopic end of the slide cylinder 71 in the position calibration component 7 is driven to extend outward to drive the buffer limit unit to move in the direction of the triangular groove 223 with the help of the L-shaped traction block 72 and the fixed block 73, until the triangular block 76 in the buffer limit unit is inserted into the triangular groove 223, and then the dividing plate 222 is used to realize The positioning of the test shaft 22 is realized to prevent it from rotating and ensure the initial position of the key block 224; thereafter, the telescopic end of the first lifting cylinder 34 can be driven to extend outward to drive the motor rotor 8 to move downward, thereby inserting the test shaft 22 into the motor rotor 8 until the lower end of the motor rotor 8 contacts the top of the support ring 221. At this time, the key block 224 is also inserted into the keyway located inside the motor rotor 8, and then the two telescopic ends of the first double-headed cylinder 35 can be driven to extend outward to loosen the motor rotor 8, and the first lifting cylinder 34 and the first pneumatic slide 33 are controlled in the same way to drive the first double-headed cylinder 35 to move in the direction of the next feeding block 410, and then the next motor rotor 8 is clamped in the same way to form a cycle.

[0045] Finally, the power module can be started to drive the motor rotor 8 to rotate a certain number of times at a certain speed with the help of the test shaft 22. At the same time, the detection module can be started to work and accurately test and calculate the dynamic balance of the motor rotor 8, so as to obtain an effective imbalance amount for improving the structure and processing technology.

[0046] After the test is completed, the moving end of the second pneumatic slide 53 in the visual inspection component 5 is driven to move to the right to drive the two second double-headed cylinders 56 to move to the right with the help of the second lifting cylinder 54 and the lifting plate 55, until the second double-headed cylinder 56 on the right moves above the test shaft 22, and then the telescopic end of the second lifting cylinder 54 is driven to extend outward or retract inward to drive the two second double-headed cylinders 56 to move downward with the help of the lifting plate 55, and at the same time, the two telescopic ends of each second double-headed cylinder 56 are driven to extend outward until the two clamping blocks 6 on the right second double-headed cylinder 56 are respectively located on the left and right sides of the motor rotor 8 placed on the test shaft 22, and then the two telescopic ends of the second double-headed cylinder 56 on the right are driven to retract inward to clamp the motor rotor 8, and then the telescopic end of the second lifting cylinder 54 is driven to retract inward or extend outward to drive the motor rotor 8 to move up until it completely leaves the test shaft 22.

[0047] Next, the movable end of the second pneumatic slide 53 is driven to move to the left to drive the motor rotor 8 to move synchronously until the motor rotor 8 is located above the bracket 58, and then the telescopic end of the second lifting cylinder 54 is driven to extend outward or retract inward to drive the motor rotor 8 to move downward until the lower end of the motor rotor 8 contacts the top of the bracket 58, and then the two telescopic ends of the second double-headed cylinder 56 can be driven to extend outward to release the motor rotor 8, and then the motor rotor 8 is placed on the top of the bracket 58.

[0048] Then, the visual camera 510 is turned on to automatically photograph the upper end connection of the motor rotor 8 and transmit the photographed data to the processing system connected thereto. The processing system automatically processes the photographed data and determines whether the wiring is complete and correct, thereby screening out the motor rotor 8 with wiring errors or omissions. The above principle is the prior art.

[0049] When the visual camera 510 is detecting the motor rotor 8 located on the top of the bracket 58, the next motor rotor 8 is similarly placed on the test shaft 22 and the dynamic balancing test is started; during this process, the telescopic end of the second lifting cylinder 54 is driven to retract inward or extend outward to drive the two second double-headed cylinders 56 to move upward, and at the same time, the movable end of the second pneumatic slide 53 is driven to move to the right to drive the two second double-headed cylinders 56 to move to the right in the same way, until the two clamping blocks 6 on the right second double-headed cylinder 56 are respectively located on the left and right sides of the motor rotor 8 placed on the test shaft 22, while the two clamping blocks 6 on the left second double-headed cylinder 56 are respectively located on the left and right sides of the motor rotor 8 placed on the top of the bracket 58.

[0050] Next, the telescopic ends of each second double-headed cylinder 56 are driven to retract inward to clamp the two motor rotors 8 at the same time, and then the second lifting cylinder 54 and the second pneumatic slide 53 are controlled in the same way to drive the two motor rotors 8 to move up first and then to the left, until the right motor rotor 8 is located above the bracket 58, and then the second lifting cylinder 54 and each second double-headed cylinder 56 are controlled in the same way to drive the two motor rotors 8 to move down first and then release, so that the right motor rotor 8 is placed on the top of the bracket 58 for automatic wiring screening with the help of the visual camera 510, and the left motor rotor 8 is placed on the belt conveyor line 512. After the belt conveyor line 512 is started, the motor rotor 8 will be driven by the belt conveyor line 512 to move to the left, thereby realizing automatic discharging.

[0051] The utility model combines the steps of dynamic balancing test and wiring inspection in the same device, thereby eliminating the step of transferring the rotor between two detection devices, thereby simplifying the testing process; it also realizes automatic clamping, moving, placing and removing of the rotor, and no manual operation is required throughout the whole process, thereby achieving the effect of saving time and labor, thereby greatly improving work efficiency.
