The push-down positioning assembly 2, the push-up positioning assembly 3 and the rotating assembly 4 will be described in detail below.

As shown in fig. 1, the press-down positioning assembly 2 includes a press-down cylinder 21, guide posts 22 (four shown), an upper mounting plate 23, a lower mounting plate 24, a movable plate 25, and a rolling mechanism 26. The two ends of the guide column 22 are respectively and fixedly mounted on the upper mounting plate 23 and the lower mounting plate 24, the lower mounting plate 24 is fixed on the support plate 1, the down-pressing cylinder 21 is mounted on the upper mounting plate, the tail end of the telescopic rod is fixedly connected to the movable plate 25, the movable plate 25 is movably sleeved on the guide column 22 through the first linear bearing 27, and the rolling mechanism 26 is mounted on the movable plate 25 and used for positioning and pressing the cylindrical workpiece 100 to be detected.

In the illustrated embodiment, the number of rolling mechanisms 26 is two, i.e., the cylindrical workpiece positioning and rotating mechanism is dual-station and can be used to simultaneously inspect two workpieces 100. It should be understood that the number of rolling mechanisms 26 may be one.

As shown in fig. 1 and 4, the rolling mechanism 26 includes an upper end clamping seat 261, two guide shafts 262, a first spring 263, a pressing block fixing block 264, two pressing blocks 265, and a roller 266.

The jacking cylinder 31 may be a small mini cylinder such as MAJ20 or the like. The jacking cylinder 31 is arranged on the connecting plate 35, and the tail end of the telescopic rod of the jacking cylinder is fixedly provided with a universal seat 36. The universal seat 36 is provided with a universal ball 361. The lower end of the mandril 32 is aligned with the universal seat 36, and the upper end is fixedly connected with the workpiece positioning inner tooling 33. Therefore, the jacking cylinder 31 jacks up, contacts the lower end of the jacking rod 32 through the universal ball and jacks up the jacking rod 32, so that the workpiece positioning inner tooling 33 jacks up the cylindrical workpiece 100. The driving motor 41 is fixedly installed on the support plate 1. The driving motor 41 is in driving connection with the belt pulley 42 through a belt, and the belt pulley 42 is fixedly connected with the rotating shaft 43 through a key groove structure. The connecting plate 35 is connected with the bearing cover 45 through two connecting rods 37, a bearing seat 46 is fixedly installed on the bearing cover 45, a stop nut 47 is installed between the belt pulley 42 and the bearing cover 45, the bearing 44 is installed in the bearing seat 46, and the rotating shaft 43 penetrates through the bearing 44 and the stop nut 47. Therefore, the rotating shaft 43 is driven to rotate by the driving motor 41.

The rotating shaft 43 has a central axial through hole, and the push rod 32 is penetrated through the central axial through hole through the oilless bushing 38 and is in driving connection with the rotating shaft 43 through a rotation-preventing ring 48 fixedly mounted on the rotating shaft 43. Specifically, the carrier rod 32 has a square portion, and the rotation preventing ring 48 has a square hole through which power transmission is achieved in cooperation with the square portion so that the carrier rod 32 can rotate as the rotating shaft 43 rotates. Therefore, the push rod 32 can be operated vertically or rotationally. The outer workpiece positioning tool 34 is fixed on the rotating shaft 43, and the supporting plate 1 is provided with a through hole which is arranged on the outer workpiece positioning tool 34. The workpiece positioning inner tooling 33 and the workpiece positioning outer tooling 34 are matched with each other for fixing the cylindrical workpiece 100. Therefore, when the rotating shaft 43 is driven by the driving motor 41 to rotate, it is ensured that both the inner and

outer tools

33, 34 for positioning the workpiece can rotate, thereby driving the cylindrical workpiece 100 to rotate.

The top rod 32 is sleeved with an upper retainer ring 321, a lower retainer ring 322 and a second spring 323, the upper retainer ring 321 abuts against the lower end of the rotating shaft 43, the lower retainer ring 322 is close to the lower end part of the top rod 32, and two ends of the second spring 323 abut against the upper retainer ring 321 and the lower retainer ring 322 respectively. When the telescopic rod of the jacking cylinder 31 retracts, the ejector rod 32 returns to the original position (reset) under the action of gravity and the second spring 323, so that the workpiece positioning inner and

outer tools

33 and 34 are reset.
