Description

Technical Field

[0001] The present invention relates to the technical field of motor detection, in particular to a motor testing robot. Background Art

[0002] A motor test robot is a device specifically designed to comprehensively test and evaluate the performance, functionality, and reliability of motors (such as electric motors and generators). By simulating the actual working environment of the motor, the test robot, in conjunction with various sensors, measuring instruments, and control systems, accurately measures and analyzes various motor parameters to ensure that the motor meets design standards and operating requirements before shipment or after repair. During the inspection process, when the motor is being tested and installed on the test tool, the operator needs to manually support it and then install and fix it. The operation is relatively cumbersome, not only consuming manpower, but also easily affecting the installation accuracy and the accuracy of the test results. At the same time, most current motor testing robots are only designed for specific types of motors (such as DC motors and AC asynchronous motors), and the test function modules are difficult to expand. For example, traditional dynamometer systems cannot directly adapt to the high-speed and high-torque testing requirements of new energy vehicle drive motors, and are also difficult to be compatible with the high-precision position control performance testing of servo motors. As a result, companies need to purchase multiple sets of special equipment, which increases costs and takes up a lot of space. For this reason, we propose a motor testing robot.

Through the movement of the cylinder 2 901 and the push rod 2 902, as well as a series of transmission structures, the torque of the connecting shaft 1107 is enhanced to meet the testing requirements of different motors; The limiting assembly 1001 is externally fixedly connected to a top block 1002, and a second spring 1003 is provided on the outside of the limiting assembly 1001. The limiting assembly 1001 is externally fixedly connected to the top block 1002, and a second spring 1003 is provided on the outside of the limiting assembly 1001.

The top of the support component 1101 is fixedly connected to the limit frame 1102, and two sliding grooves 1103 are provided on the outside of the limit frame 1102. The sliding grooves 1103 are slidably connected to the sliding blocks 1104. The two sliding blocks 1104 are fixedly connected to the side close to each other with a support block 1105. The top of the support block 1105 is fixedly connected to a connecting cylinder 1106, and the connecting cylinder 1106 is rotatably connected to the inside of the connecting cylinder 1107. A coupling 1108 is installed on the side of the connecting shaft 1107 away from the connecting cylinder 1106; the connecting cylinder 1106 and the support block 1105 installed on the outside of the connecting shaft 1107 will also slide inside the limit frame 1102 with the assistance of the sliding block 1104, and then the connecting shaft 1107 is auxiliary supported by the support block 1105 and the connecting cylinder 1106.

[0019] When testing the motor through the motor testing robot, the motor is first placed on the top of the arc pressure plate 2 502, and then the arc pressure plate 2 502 is pressed downward by the weight of the motor itself, and then the arc pressure plate 2 502 is pressed downward on the elastic component 6, so that the arc pressure plate 2 502 slides into the lower pressing groove 501. At this time, the arc pressure plate 2 502 will pull the connecting rod 504 through the connecting block 1 503 when sliding downward, and then the connecting rod 504 cooperates with the connecting block 2 505 to pull the two arc pressure plates 3 506 downward while the two arc pressure plates 3 506 are clamped to the adjacent side of the motor on the top of the arc pressure plate 2 502. At this time, the drive component 3 is started, and then After the driving assembly 3 is started, the cylinder 1 301 cooperates with the push rod 1 302 to push the arc pressure plate 1 4 toward the motor, and then the arc pressure plate 1 4 cooperates with the limit block 401 and the installation shaft 402 to drive the arc shaft 403 to approach the motor to be tested, and then the arc shaft 403 cooperates with the slide groove 404 to slide outside the threaded rod 507 fixed on the top of the arc pressure plate 3 506 until the arc pressure plate 1 fully contacts the top of the motor, and then the fastening ring 508 is screwed to make the fastening ring 508 threaded and rotated outside the threaded rod 507 and limit the top of the slide groove 404, thereby completing the fixation of the motor to be tested. At the same time, it can adapt to motors of different sizes, making the installation operation more convenient; After the motor is installed on the motor testing robot, when testing its torque, in order to better align the coupling 1108 with the motor to be tested, first start the second cylinder 901 and the second push rod 902 to push or retract the fixed block 903 upward, so that the connecting shaft 1107 cooperates with the coupling 1108 and the output end of the motor to be aligned. Then, the connecting shaft 1107 is aligned with the output end of the motor through the coupling 1108; Then, due to the different sizes of the motors, the torque generated is also different. In order to make the connecting shaft 1107 adapt to the torque generated by the motor, it is only necessary to pull the top block 1002 to make the top block 1002 slide out from the inside of the limiting hole 906 in cooperation with the limiting assembly 1001, and then toggle the rotating piece 9010 so that the rotating piece 9010 cooperates with the rotating ring 9011 to rotate inside the limiting cover 904, and then make the rotating ring 9011 cooperate with the arc groove 9012 to push the rotating rod 9013, so that the rotating rod 9013 is rotated. When 013 slides inside the arc groove 9012, the mounting block 9014 and the connecting shaft 1107 through which the arc-shaped fastening block 9015 passes inward are brought into contact, thereby increasing friction. After the adjustment is completed, the top block 1002 is released, so that the second spring 1003 pulls the limiting assembly 1001, causing the limiting assembly 1001 to slide into the limiting hole 906 provided inside the limiting bar 905 for limiting. At this time, the contact between the arc-shaped fastening block 9015 and the outside of the connecting shaft 1107 increases friction, thereby enhancing the torque. Then, after the motor output end and the coupling 1108 are installed and limited, the current intensity transmitted to the motor is displayed through the display component 7 in conjunction with the display screen 1 702, and then the torque of the connecting shaft 1107 is detected through the detection component 8 in conjunction with the connecting tube 1106, and displayed through the detector 801 and the display screen 2 802.

[0020] Example 2 In this second embodiment, other structures remain unchanged. The difference from the first embodiment is that when the limit cover 904 is pushed upward by the cylinder 2 901 and the push rod 2 902 to cooperate with the connecting shaft 1107 to move upward, the connecting tube 1106 and the support block 1105 installed on the outside of the connecting shaft 1107 will also slide inside the limit frame 1102 with the assistance of the sliding block 1104, and then the connecting shaft 1107 is auxiliary supported by the support block 1105 and the connecting tube 1106.
