At the same time, when the input shaft is placed in the middle of the detection groove 12, the middle of the input shaft contacts the top of the support plate 14 and presses the support plate 14 downward. The support plate 14 is subjected to pressure and moves downward through the elastic contraction of the first spring 13. The placed input shaft is observed to be horizontal through the spirit level 15 to determine whether the diameters at both ends of the input shaft are qualified. Detecting the input shaft diameter through the spirit level 15 can effectively reduce the error caused by manual measurement, reduce the problem of inconsistent measurement results caused by hand fatigue due to long-term measurement, and can effectively reduce the efficiency reduction caused by manual measurement with a micrometer, and the spirit level 15 can effectively make the detection process simpler. Effectively detecting the diameters at both ends of the input shaft can reduce the deviation caused by processing, which leads to difficulties in assembly during use or inability to work after assembly, and can effectively improve the processing quality and production efficiency of the input shaft.

[0024] like Figure 1 and Figure 3As shown, the top of the detection platform 1 is fixedly connected to two fixing plates 2; the two fixing plates 2 are arranged opposite to each other; the top of the detection platform 1 is fixedly connected to two second springs 21; the two second springs 21 are arranged on one side of the corresponding fixing plate 2; the side wall of the fixing plate 2 is slidably connected to a positioning plate 22; the other end of the second spring 21 is fixedly connected to the bottom of the positioning plate 22; the side wall of the positioning plate 22 is fixedly connected to two guide plates 23; the two guide plates 23 are arranged obliquely; when working, one end of the input shaft is placed inside the positioning plate 22, and the other end of the input shaft is placed in the middle of the corresponding positioning plate 22, and the guide plate 23 is flexibly arranged. The guide plate 23 guides the input shaft, and the positioning plate 22 positions the input shaft. When the input shaft is placed in the middle of the detection groove 12, the input shaft presses the positioning plate 22 to make it slide downward on the side wall of the fixed plate 2. When the input shaft is taken out after the detection, the positioning plate 22 is elastically reset by the second spring 21.

[0025] like Figure 1 and Figure 3 As shown, the side wall of the fixing plate 2 is fixedly connected to the first magnet 3; the middle of the positioning plate 22 is fixedly connected to two telescopic rods 31; the ends of the two telescopic rods 31 are fixedly connected to the first rubber pads 32; the side wall of the first rubber pad 32 is fixedly connected to the second magnet 33; the second magnet 33 is fixedly connected to the side close to the telescopic rod 31; the first magnet 3 and the second magnet 33 repel each other when they are close to each other; during operation, when input shafts of different lengths are tested, the first rubber pad 32 contacts the end of the input shaft, and the longer input shaft applies pressure to the telescopic rod 31, causing the end of the telescopic rod 31 to contract, so that the input shaft 31 is compressed. The middle of the input shaft is always kept in the center position. When the detection is completed, the positioning plate 22 moves upward after being reset by the second spring 21. When the first magnet 3 and the second magnet 33 are close to each other, the first rubber pad 32 moves outward through repulsion, and the telescopic rod 31 is stretched at the same time. The first rubber pad 32 can effectively keep the detection position of input shafts of different lengths consistent, effectively reduce the problem of measurement errors caused by different input shaft lengths, effectively reduce the operation time caused by manual adjustment, effectively reduce the waste of time and cost caused by changing equipment, and effectively improve the overall work efficiency.

[0027] like Figure 1 As shown, the middle part of the support plate 14 is threadedly connected with two threaded rods 5; the two threaded rods 5 are arranged at both ends of the support plate 14; the top of the threaded rod 5 is fixedly connected with a second rubber pad 51; during operation, when the diameter of the middle part of the input shaft is different, the threaded rod 5 is twisted to make the threaded rod 5 rotate in the middle part of the support plate 14, and the height of the top of the two threaded rods 5 in the support plate 14 is adjusted according to the middle diameter of the input shaft, so that the distance difference between the two second rubber pads 51 is equal to the distance difference between the middle diameter of the input shaft, and when the middle part of the input shaft is placed on the support plate 14, the support plate 14 is still horizontal, and the threaded rod 5 and the second rubber pad 51 can effectively adapt to the uneven part of the middle part of the input shaft, effectively reducing the problem of inaccurate measurement results caused by the uneven part during measurement, and can and can simultaneously measure the middle diameter of the input shaft, and can adapt to a wide range of input shaft types and measure them.

The suction cup 61 can effectively keep the input shaft stable during diameter detection, effectively reduce measurement errors caused by movement or shaking, and effectively make the detection platform 1 not easily moved by external impact, thereby increasing stability and reliability during the measurement process.

[0029] During operation, according to the distance difference between the two ends of the input shaft, one of the electric push rods 10 is controlled to adjust the height of the electric push rod 10 so that the height difference between the two electric push rods 10 is equal to the height difference of the input shaft, and the input shaft is placed in the detection frame 11 so that the input shaft is between the two detection slots 12, and it is observed whether the diameters of the two ends of the input shaft are on the specified scale line 16. At the same time, when the input shaft is placed in the middle of the detection slot 12, the middle of the input shaft contacts the top of the support plate 14, and the support plate 14 is pressed downward. The support plate 14 is subjected to pressure and elastically contracts through the first spring 13 and moves downward, and the input shaft is placed. The input shaft after placement is observed to be level by a level meter 15, so as to judge whether the diameters of both ends of the input shaft are qualified. One end of the input shaft is placed inside the positioning plate 22, and then the other end of the input shaft is placed in the middle of the corresponding positioning plate 22. The guide plate 23 is flexibly set so that the guide plate 23 guides the input shaft, and the input shaft is positioned by the positioning plate 22. When the input shaft is placed in the middle of the detection groove 12, the input shaft presses the positioning plate 22 to make it slide downward on the side wall of the fixed plate 2. When the input shaft is taken out after the detection is completed, the positioning plate 22 is elastically reset by the second spring 21. When testing input shafts of different lengths, the first rubber pad 32 contacts the end of the input shaft, and the longer input shaft applies pressure to the telescopic rod 31, causing the end of the telescopic rod 31 to contract, so that the middle of the input shaft is always kept in the center position. When the test is completed, the positioning plate 22 moves upward after being reset by the second spring 21. When the first magnet 3 and the second magnet 33 are close to each other, the first rubber pad 32 moves outward through repulsion, and the telescopic rod 31 is stretched at the same time. When the input shaft needs to be tested, the bristles 43 are pulled downward to make the slider 41 slide inside the slide groove 4. The bristles 43 clean the side walls of the detection groove 12. When the diameter of the middle part of the input shaft is different, the threaded rod 5 is twisted to make the threaded rod 5 rotate in the middle part of the support plate 14, and the height of the top of the two threaded rods 5 in the support plate 14 is adjusted according to the diameter of the middle part of the input shaft, so that the distance between the two second rubber pads 51 is equal to the distance between the middle diameter of the input shaft. When the middle part of the input shaft is placed on the support plate 14, the support plate 14 is still horizontal. The detection table 1 is placed on a desktop or platform, and the suction cup 61 contacts the platform to generate suction to fix the detection table 1 at a specified position.
