[0027] The following is combined with Figure 1-6 This application is described in further detail.

[0028] An automatic detection device for a rotating shaft, such as Figure 1 and Figure 2 As shown, it includes a frame 1 and a conveying platform 2. The conveying platform 2 is arranged on the frame 1 to horizontally convey the rotating shaft 3. A loading mechanism 4, a measuring instrument 5 and a discharging mechanism 6 are sequentially arranged on the frame 1 along the conveying direction of the conveying platform 2. The rotating shaft 3 is loaded onto the conveying platform 2 by the loading mechanism 4, and then inspected by the measuring instrument 5. After the inspection is completed, it is output from the discharging mechanism 6, thereby realizing the automated inspection of the rotating shaft 3, which is suitable for large-scale inspection of the rotating shaft 3.

[0029] like Figure 1 and Figure 2 As shown, the loading mechanism 4 includes a feeding robot 7 and a hopper 8. A large number of rotating shafts 3 that need to be inspected are stored in the hopper 8, and a lifting component for lifting the rotating shafts 3 one by one is provided on one side of the hopper 8. The lifting component includes a lifting plate 9 and a lifting cylinder 10. The lifting cylinder 10 drives the lifting plate 9 to rise vertically. In actual use, the lifting plate 9 is driven to rise with the help of the lifting cylinder 10 to lift the rotating shaft 3 to the top of the hopper 8, so that the feeding robot 7 can clamp it, and then the feeding robot 7 transports it to the conveying platform 2.

[0030] like Figure 2 and Figure 3As shown, the conveyor platform 2 includes a frame 11, a sprocket 12 and a conveyor chain 13. The conveyor chain 13 is rotatably connected to the frame 11. The conveyor chain 13 is provided with two sprockets 12 arranged in parallel and connected at both ends of the frame 11. A conveying motor 14 is provided on the frame 11 to drive one of the sprockets 12 to rotate, and support blocks 15 are arranged at intervals on the conveyor chain 13 along its conveying direction. The top of the support block 15 has a positioning groove 16 for the end of the rotating shaft 3 to be placed. The positioning groove 16 is triangular in shape to facilitate the stable placement of the end of the rotating shaft 3 to prevent the rotating shaft 3 from falling during the conveying process.

[0031] like Figure 1 and Figure 3 As shown, a lifting mechanism 17 is provided below the frame 1 corresponding to the measuring instrument 5. The lifting mechanism 17 is used to lift the rotating shaft 3 on the conveying platform 2. At the same time, a driving mechanism 18 is provided on the frame 1. The driving mechanism 18 is used to drive the lifted rotating shaft 3 to rotate, so that the rotating shaft 3 can be in a rotating state when the measuring instrument 5 detects the rotating shaft 3. The detection of the rotating shaft 3 is more comprehensive, the detection accuracy is more guaranteed, and the detection of shaft runout data can be realized while the diameter detection is realized.

[0032] like Figure 3 and Figure 4 As shown, the jacking mechanism 17 includes a jacking cylinder 19 and a support platform 20. The jacking cylinder 19 drives the support platform 20 to rise and fall vertically. The support platform 20 has a placement block 21 for placing the rotating shaft 3. The placement block 21 corresponds to the two ends of the rotating shaft 3. The top of the placement block 21 is also provided with a positioning groove 16 for the end of the rotating shaft 3 to be placed, so as to improve the stability of the placement of the rotating shaft 3. The jacking mechanism 17 is arranged between the two conveying chains 13, which can lift the rotating shaft 3 without interfering with or affecting the transportation of the conveying platform 2.

[0033] like Figure 5As shown, the frame 1 is provided with a mounting frame 22 for installing the driving mechanism 18 and the measuring instrument 5. The driving mechanism 18 includes a driving motor 23, a top table 24 and a driving cylinder 25. The driving cylinder 25 and the top table 24 move horizontally. The driving motor 23 is connected with a transmission sleeve 26. The transmission sleeve 26 is transmitted to the output end of the driving motor 23 through a synchronous belt and a synchronous wheel. One end of the rotating shaft 3 has a flat orientation, which is inserted into the transmission sleeve 26 to realize circumferential linkage. The inside of the transmission sleeve 26 and the top table 24 are provided with a top 27 for abutting against the two ends of the rotating shaft 3. With the help of the top 27, the rotating shaft 3 can be well set up, and then the rotating shaft 3 can be driven to rotate with the help of the driving motor 23 to achieve good detection. In the embodiment, the driving mechanism 18 is connected to the mounting frame 22 by sliding horizontally along the axial direction of the transmission sleeve 26. The mounting frame 22 is provided with a horizontal cylinder 36 that drives the driving mechanism 18 to move horizontally. The driving mechanism 18 has a fixed plate 37 pushed by the horizontal cylinder 36. The mounting frame 22 is provided with a reset spring 38 that drives the driving mechanism 18 to reset horizontally. In actual use, the driving cylinder 25 drives the rotating shaft 3 to move axially so that its end cooperates with the transmission sleeve 26, and then it can be rotated under the drive of the driving motor 23. After the detection is completed, the horizontal cylinder 36 drives the driving mechanism 18 to move axially as a whole so that the transmission sleeve 26 is disconnected from the rotating shaft 3. After the rotating shaft 3 drops, the driving mechanism 18 moves and resets under the action of the reset spring 38.

[0034] like Figure 5 As shown, the measuring instrument 5 is an online projection image measuring instrument. The measuring instrument 5 is horizontally slidably connected to the mounting frame 22. The horizontal sliding direction of the measuring instrument 5 is perpendicular to the conveying direction of the conveyor platform 2. A driving source 28 for driving the measuring instrument 5 to move is provided on the mounting frame 22. The driving source 28 can be driven by a motor and a screw rod. The measuring instrument 5 can move along the axial direction of the rotating shaft 3 during the detection process, which makes the detection of the rotating shaft 3 more comprehensive and accurate, and improves the detection accuracy and effect.

[0035] like Figure 1 and Figure 6As shown, the discharging mechanism 6 is arranged at one end of the frame 1 away from the feeding mechanism 4, and the discharging mechanism 6 includes a discharging hopper 29, a rejection component 30 and a receiving box 31. The discharging hopper 29 is used to receive the rotating shaft 3 that has passed the output inspection, and the rejection component 30 is used to reject the rotating shaft 3 that has failed the inspection and drop it into the receiving box 31. The discharging hopper 29 is tilted downward to facilitate the automatic rolling of the rotating shaft 3. The rejection component 30 includes a lifting cylinder 32 and a lifting plate 33. The lifting plate 33 is fixed to the output end of the lifting cylinder 32. The lifting cylinder 32 drives the lifting plate 33 to rise and fall vertically. A drop opening 34 is provided on the side of the discharging hopper 29 close to the conveying platform 2, and the lifting plate 33 and the drop opening 34 are shaped The material receiving box 31 is adapted to the shape, and the material receiving box 31 is located below the blanking port 34, and the top wall of the lifting plate 33 is also tilted and the tilt angle is consistent with the discharge hopper 29. In this way, when the rotating shaft 3 is qualified, the lifting cylinder 32 drives the lifting plate 33 to rise, and the lifting plate 33 is adapted to the blanking port 34. The top wall of the lifting plate 33 is flush with the bottom wall of the discharge hopper 29. At this time, the rotating shaft 3 that falls into the lifting plate 33 will roll down and drop along the discharge hopper 29. When the rotating shaft 3 is unqualified, the lifting cylinder 32 drives the lifting plate 33 to descend, and the lifting plate 33 is lower than the discharge hopper 29. At this time, the rotating shaft 3 falls to the lifting plate 33 and rolls into the material receiving box 31, thereby realizing automatic classification of qualified and unqualified products.

[0036] like Figure 6 As shown, one side of the lifting plate 33 has a receiving portion 35 extending toward the conveying platform 2. With the help of the design of the receiving portion 35, the rotating shaft 3 on the conveying platform 2 can be better received, thereby improving the stability of the rotating shaft 3 falling onto the lifting plate 33 and reducing the situation where the rotating shaft 3 accidentally falls.

[0037] The working principle of the embodiment of the present application is as follows: the loading mechanism 4 loads the rotating shaft 3 onto the conveying platform 2. When the rotating shaft 3 is conveyed to the measuring instrument 5, the lifting mechanism 17 drives the rotating shaft 3 to lift and separate from the conveying platform 2, and then rotates under the action of the driving mechanism 18. During the rotation of the rotating shaft 3, the measuring instrument 5 detects it. After the detection is completed, the lifting mechanism 17 takes over the rotating shaft 3 and lowers it back to the conveying platform 2. Finally, under the action of the conveying platform 2, it is conveyed to the discharging mechanism 6 to complete the discharging, and automatic classification of qualified and unqualified products is realized during the discharging process.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
