Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: A valve stem taper runout detection device includes a workbench 1. A mounting frame 2 is fixedly connected to the left side of the top end of the workbench 1. A conveyor belt 3 is installed inside the mounting frame 2.

A clamping mechanism 5 is installed at the output end of the cylinder 1 4. The position of the suction cup 3 23 corresponds to the rear side of the clamping mechanism 5.
[0025] Specifically, the workbench 1 fixes the mounting frame 2, so that the position of the mounting frame 2 is fixed. The valve can be conveyed through the conveyor belt 3 on the mounting frame 2. The conveyed valve can be adsorbed by the suction cup 3 23 on the right side of the conveyor belt 3. The cylinder 1 4 can drive the clamping mechanism 5 to move, so that the valve on the suction cup 3 23 can be clamped by the clamping mechanism 5.
[0026] Referring to Figures 1-3, a support frame 6 is fixedly connected to the rear side of the top end of the workbench 1. A first slide rail 7 is installed at the top end of the support frame 6. A second cylinder 8 is installed on the left side of the support frame 6. A moving frame 9 is slidably connected to the outside of the first slide rail 7. The output end of the second cylinder 8 is fixedly connected to the left end of the moving frame 9. A third cylinder 10 is installed on the left front side of the front end of the moving frame 9. A fourth cylinder 11 is installed on the right front side of the front end of the moving frame 9. A first suction cup 12 is installed at the output end of the third cylinder 10. A second suction cup 13 is installed at the output end of the fourth cylinder 11. A control cabinet 27 is fixedly connected to the inside of the workbench 1. A display 28 is fixedly connected to the front side of the top end of the workbench 1.
[0027] Specifically, the workbench 1 fixes the support frame 6, enabling the position of the support frame 6 to be fixed. Through the first slide rail 7 and the second cylinder 8 on the support frame 6, and with the moving frame 9 slidably connected to the first slide rail 7, the second cylinder 8 can drive the moving frame 9 to move on the first slide rail 7. The third cylinder 10 and the fourth cylinder 11 can drive the first suction cup 12 and the second suction cup 13 to move. The workbench 1 fixes the control cabinet 27 and the display 28, enabling the positions of the control cabinet 27 and the display 28 to be fixed.
[0028] Refer to Figure 1 , Figure 2 and Figure 4 , a lifting mechanism 14 is installed on the front side of the top end of the workbench 1. A fifth cylinder 15 is installed on the outside of the lifting mechanism 14. The output end of the fifth cylinder 15 is fixedly connected to a limiting rod 16. A motor 17 is installed on the front right side of the right end of the lifting mechanism 14. A turntable 18 is installed on the rear right side of the right end of the lifting mechanism 14. A detection frame 19 is fixedly connected to the middle side of the top end of the workbench 1. The turntable 18 is directly in front of the detection frame 19. The fourth cylinder 11 is directly above the detection frame 19. A conical surface detection sensor 20 is installed on the upper side of the detection frame 19. A rod part detection sensor 21 is installed in the middle side of the detection frame 19. A thimble 22 is installed on the lower side of the detection frame 19.
[0029] Specifically, by installing the lifting mechanism 14 on the workbench 1, the lifting mechanism 14 can drive the limiting rod 16 and the turntable 18 to move to an appropriate height. By starting the fifth cylinder 15, the limiting rod 16 can be driven to abut against the valve for limiting. By the motor 17, the turntable 18 can be driven to rotate the valve. With the valve placed on the upper side of the thimble 22, the valve can be detected by the conical surface detection sensor 20 and the rod part detection sensor 21. The workbench 1 fixes the detection frame 19, enabling the position of the detection frame 19 to be fixed.
[0030] Refer to Figure 1 and Figure 2, a blanking component is provided on the upper right side of the workbench 1. The blanking component includes a moving mechanism 24. The moving mechanism 24 is installed on the upper right side of the workbench 1. A first blanking chute 25 is installed at the top of the moving mechanism 24. The conveyor belt 3, the first suction cup 12, the second suction cup 13, and the first blanking chute 25 are all on the same horizontal plane. Three second blanking chutes 26 are fixedly connected to the upper right side of the workbench 1, and the three second blanking chutes 26 are directly to the right of the moving mechanism 24.
[0031] Specifically, the moving mechanism 24 on the workbench 1 can drive the first blanking chute 25 to move, so that the position of the first blanking chute 25 can correspond to the positions of the three second blanking chutes 26. Since the conveyor belt 3, the first suction cup 12, the second suction cup 13, and the first blanking chute 25 are all on the same horizontal plane, the detection process can operate normally.
[0032] Working principle: When it is necessary to detect the valve, start the conveyor belt 3 to drive the valve to move to the position of the third suction cup 23, and adsorb it through the third suction cup 23. Then start the clamping mechanism 5 to clamp it. Then drive the clamping mechanism 5 to move to the lower side of the first suction cup 12 through the first cylinder 4, and adsorb it through the first suction cup 12. Then start the third cylinder 10 and the fourth cylinder 11 to drive the first suction cup 12 and the second suction cup 13 to move upward. Then start the second cylinder 8 to drive the moving frame 9 to move on the first slide rail 7, so that the valve that has been detected on the second suction cup 13 can be transported to the first blanking chute 25, and the valve on the first suction cup 12 can be placed on the thimble 22. Then start the fifth cylinder 15 to drive the limiting rod 16 to limit the valve, and start the motor 17 to drive the turntable 18 to rotate, so as to drive the valve to rotate. Then detect the valve through the conical surface detection sensor 20 and the rod part detection sensor 21. By reversing and repeating the operations of each structure, the valve can be automatically detected;
[0033] In addition, when the detected valve falls onto the first blanking chute 25, whether there is a problem with the quality detected by the sensor is checked. Then the moving mechanism 24 can drive the blanking chute 25 to move to the corresponding positions of the three second blanking chutes 26 respectively, so as to classify the valves that have completed the detection.
[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
