A fixed plate 14 is fixedly connected to the top of the platform 1, and a geared motor 15 is fixedly connected to the top of the fixed plate 14. A drive wheel 16 is fixedly connected to the output end of the geared motor 15. A driven wheel 17 is rotatably connected to the bottom of the fixed plate 14. The transmission belt 18 rotates on the surface of the drive wheel 16 and the driven wheel 17. A rotating connector 19 is fixedly connected inside the driven wheel 17, and a combined shaft 20 is inserted into the rotating connector 19. The combined shaft 20 rotates inside the platform 1 and inside the lifting cylinder 13. A sensing ring is fixedly connected to the top of the combined shaft 20. 21. The sensing ring 21 is located above the protective shell 2. A spring 22 is sleeved on the surface of the combined shaft 20. The top of the spring 22 is fixedly connected to the bottom of the rotating connector 19. A workpiece insertion frame 23 is fixedly connected to the bottom of the combined shaft 20. The entire structure is driven to descend by an external lifting device. With the linkage structure composed of a reduction motor 15, a drive wheel 16, a transmission belt 18, a driven wheel 17, and the combined shaft 20, the workpiece insertion frame 23 can automatically align with the shell fixing slot and insert during rotation, realizing automatic shell fitting and fixing. There is no need for repeated manual calibration of the position. This reduces tedious and time-consuming operation steps and avoids the impact of human operation errors on subsequent measurement accuracy, effectively improving the shell positioning efficiency and measurement accuracy.

[0023] A protective shell 2 is fixedly connected to the top of the assembly platform 1, and a mounting plate 3 is fixedly connected to one side surface of the protective shell 2.

[0024] The mounting plate 3 has three monitoring probes 4 fixedly connected inside, and the assembly platform 1 has a guide sleeve 5 fixedly connected inside.

[0025] The surface of the guide sleeve 5 is provided with three guide grooves 6, and the inner walls of the three guide grooves 6 are respectively slidably connected to guide sliders 7.

[0026] Guide slides 8 are fixedly connected to one side surface of the three guide sliders 7, and the guide slides 8 slide inside the assembly table 1.

[0027] The bottom of the guide sleeve 5 is fixedly connected to the base frame 9, and three height measuring instruments 10 are fixedly connected inside the base frame 9.

[0028] The bottom of the three height measuring devices 10 is fixedly connected to a measuring disk 11, and the top of the measuring disk 11 is fixedly connected to three guide rods 12. The three guide rods 12 slide inside the base frame 9 respectively.

[0029] A lifting cylinder 13 is fixedly connected to the top of the measuring plate 11, and the lifting cylinder 13 is fixedly connected to three guide sliders 7.

[0030] The lifting cylinder 13 slides inside the base frame 9, inside the guide sleeve 5, and inside the assembly platform 1.

It can also assist the height measuring device 10 in accurately collecting data by changing the compression state, and at the same time, it can also play the role of resetting the component. In addition, the lifting cylinder 13 drives the guide slider 7 and the guide slide 8 to form a guide limit structure, which can provide guide limit for the measuring component to prevent deviation, and ensure that the measuring component can achieve accurate measurement. This not only ensures the stability and accuracy of the measurement results, but also improves the efficiency of a single measurement.

[0031] Working principle and usage process of this utility model: In use, the measuring structure is first installed on the external lifting equipment. The lifting equipment is then controlled to lower the structure. At the same time, the housing of the electric drive system to be measured is placed in the placement area below the measuring structure. The geared motor 15 is started, which drives the driven wheel 17 to rotate through the drive wheel 16 and the transmission belt 18. The driven wheel 17 drives the combined shaft 20 to rotate through the rotating connector 19, so that the workpiece insertion frame 23 is aligned with the housing fixing slot and inserted during the descent, thus completing the automatic adaptation and fixing of the housing. After the housing is fixed, the lifting device continues to drive the measuring structure to descend. At this time, the workpiece insertion frame 23, the combined shaft 20, and the sensing ring 21 are forced to move upward and compress the spring 22. When the sensing ring 21 moves to the monitoring area of ​​the monitoring probe 4, the device determines that it has switched from the fixed state to the measuring state. When the workpiece insertion frame 23 contacts and pushes the measuring disk 11 and the lifting cylinder 13 to move, the spring 22 continues to compress, and the height measuring device 10 is compressed synchronously to measure the height of the housing. At the same time, the lifting cylinder 13 drives the guide slider 7 to slide in the guide groove 6 and the guide slide 8 to slide in the combined table 1, which plays a guiding and limiting role. Then the lifting device stops and the measurement is completed. After the measurement is completed, start the geared motor 15 to rotate in the reverse direction, so that the workpiece insertion bracket 23 is separated from the housing. Then control the lifting device to rise. During the rising process, the spring 22 rebounds and pushes the combined shaft 20 to reset. The lifting cylinder 13 and the measuring plate 11 return to their positions synchronously. The guide slide 8 resets with the guide slider 7. At this time, the housing is no longer fixed and can be removed to complete a single measurement.
