[0031] Please refer to Figures 5-7 , the detection device 7 in the figure includes three cylinders 8 and a bottom support plate 9 fixedly connected to the body 1. The piston rods of the cylinders 8 located on both sides are respectively fixedly connected with a pressing plate 10 and an insertion rod 11. The pressing plate 10 cooperates with the bottom support plate 9 to detect the height of the part, and the insertion rod 11 cooperates with the bottom support plate 9 to detect the inner diameter of the part. The piston rod of the cylinder 8 located in the middle is fixedly connected with a lifting plate 12, and two pressing rods 13 are elastically matched on both sides of the lifting plate 12. Detection sensors are provided on the pressing plate 10, the insertion rod 11 and the pressing rods 13.

[0032] Please refer to Figures 8-10 , in the illustrated rotation assembly 14, there are two pressing blocks 15 symmetrically distributed and located at the central position of the clamping device. The pressing blocks 15 are located in the inner diameter of the part. The two pressing blocks 15 are in pressing cooperation. A support rod 16 that contacts the inner wall of the inner diameter of the part is movably fitted on the outer surface of the pressing block 15. Inside the pressing block 15, the support rod 16 is moved to press against the inner diameter of the part through an expansion assembly 28. A rotating rod 17 is movably fitted at the end of the pressing block 15. A closed annular groove 18 is formed on the outer surface of the rotating rod 17. A sliding column 19 is slidably fitted in the annular groove 18. The end of the sliding column 19 is fixedly connected to a collar 20 sleeved on the outer surface of the rotating rod 17. A power assembly 21 for driving the collar 20 to move up and down is provided on the outer surface of the collar 20. An actuating assembly 31 is provided between the pressing block 15 and the rotating rod 17 to drive the rotating rod 17 to rotate after the expansion assembly 28 operates.

[0033] Please refer to Figures 8-9 , in the illustrated power assembly 21, it includes a servo motor 22 fixedly connected to the bottom support plate 9. The output shaft of the servo motor 22 is fixedly connected to a gear 23. Two rack plates 24 are in meshing contact on both sides of the gear 23. The two rack plates 24 are slidably fitted on both sides with a limit frame plate 25 fixedly connected to the bottom support plate 9. The ends of the two rack plates 24 are fixedly connected to a connecting rod 26 fixedly connected to the collar 20. Activity grooves 27 for movably fitting the connecting rod 26 are formed on the pressing plate 10, the inserting rod 11, and the bottom support plate 9.

[0034] Please refer to Figures 11-12 , in the illustrated expansion assembly 28, it includes a sliding block 29. The side of the sliding block 29 is at an inclined angle. A limit post 30 is fixedly connected to the end of the sliding block 29. The limit post 30 and the sliding block 29 are both in pressing cooperation with the support rod 16. A connecting assembly 35 is provided between the plurality of support rods 16.

[0035] Among them, the end of the pressing block 15 has a frustum structure with a narrow inner part and a wide outer part.

[0036] In this embodiment, the parts are continuously conveyed onto the clamping plate 6 by the conveying device 2, and the parts are precisely clamped by a plurality of uniformly arranged clamping workpieces on the clamping plate 6. The stepping device 3 makes the clamping workpieces on the clamping plate 6 move intermittently and stops for a period of time. During the stopped period, the air cylinder 8 drives the pressure plate 10, the insertion rod 11, the lifting plate 12 and the pressure rod 13 to move downward, so that the pressure plate 10 cooperates with the bottom support plate 9 to press against the top and bottom ends of the parts to detect the height of the parts. The insertion rod 11 is inserted into the inner diameter of the parts to detect the inner diameter of the parts. The two pressure rods 13 press against the outer surface of the parts, so as to detect the outer diameter of the parts. A regulating valve is provided at the end of the pressure rod 13 to automatically adjust the position of the pressure rod 13, ensure that the downward moving pressure rod 13 smoothly presses against the outer surface of the parts, and ensure that the pressure rod 13 tightly presses against the outer surface of the parts. The detection sensor reads the corresponding data and feeds it back to the system;

[0037] When the pressure plate 10 moves downward to press against the parts, due to the setting of the movable groove 27, the connecting rod 26, the pressure block 15 and the rotating rod 17 do not conflict with the pressure plate 10. The rotating rod 17 and the pressure block 15 are both located on the axis of the through hole of the parts. The servo motor 22 operates to drive the gear 23 to rotate, so that the two toothed plates 24 move towards each other along the limiting frame plate 25, drive the two connecting rods 26 to move towards each other, drive the collar 20 to move, and thus drive the rotating rod 17 and the pressure block 15 to move downward. When the two pressure blocks 15 press against each other and contact, under the action of the movable assembly 31, the rotating rod 17 remains in place. Under the action of the continuously moving collar 20, the sliding column 19 and the annular groove 18, the rotating rod 17 rotates one week and moves downward, so that the pressure block 15 rotates, and drives the sliding block 29 and the limiting column 30 to move downward relative to the pressure block 15, so that the sliding block 29 presses against the support rod 16, causing the support rod 16 to expand. A plurality of support rods 16 move away from each other, so that the outer ends of the support rods 16 press against and are fixed on the inner wall of the inner diameter of the parts. Cooperating with the rotating rotating rod 17 and the pressure block 15, the parts rotate, and the parts rotate with the axis of the inner diameter of the parts as the rotation axis. Similarly, the insertion rod 11 is the same;

[0038] It should be noted that during the rotation process, the clamping workpieces on the clamping plate 6 at the position of the rotating parts are slightly loosened and adjusted to facilitate the rotation of the parts.

[0039] Embodiment Two

[0040] This Embodiment Two is a further supplement and explanation of Embodiment One. Please refer to Figures 11-12, the movable component 31 in the figure includes a first movable rod 32 penetrating the rotating rod 17 and the pressing block 15. The first movable rod 32 is fixedly connected to the sliding block 29. Second movable rods 33 penetrating the rotating rod 17 are provided on both sides of the first movable rod 32. The ends of the second movable rods 33 are fixedly connected to the first movable rod 32. A compression spring 34 is sleeved on the outer surface of the second movable rod 33. Both ends of the compression spring 34 are respectively connected to the first movable rod 32 and the rotating rod 17.

[0041] In this embodiment, when the two pressing blocks 15 are in pressing contact, the collar 20 that continues to move downward, through the sliding column 19 and the annular groove 18, causes the rotating rod 17 to move downward and rotate self - sufficiently, so that the two pressing blocks 15 rotate self - sufficiently at the original position. The rotating rod 17 moving relative to the pressing block 15 drives the first movable rod 32 to move, and the second movable rod 33 moves relative to the pressing block 15, and the compression spring 34 is compressed.

[0042] Embodiment Three

[0043] This Embodiment Three is a further supplement and explanation of Embodiment Two. Please refer to Figures 11-12 , the connecting component 35 in the figure includes a plurality of interconnected elastic ropes 36 distributed in a circle. The elastic ropes 36 are connected to the end of the support rod 16. A plurality of sliding grooves 37 are distributed in a circle on the sliding block 29 and the limiting column 30. The elastic ropes 36 slide in the sliding grooves 37.

[0044] In this embodiment, while the sliding block 29 and the limiting column 30 move downward to press the support rod 16, the elastic ropes 36 are stretched and slide in the sliding grooves 37.
