The cylinder 7 can be placed in a loading position in a horizontal posture.

In this embodiment, the rotation structure 3 is covered with a protecting cover, and the protecting cover does not affect the placement and rotation of the cylinder, and is used for shielding external impurities.

Specifically, the rotation mechanism 3 includes a loading assembly and a first driving assembly. The loading assembly comprises a shaft body 31 and a friction roller 32. Wherein the two shaft bodies 31 are arranged side by side and the central axis extends in the first direction of the shaft bodies 31. The shaft body 31 is mounted on the housing body 1 through a bearing housing so as to be rotatable about its own central axis. Each shaft body 31 is provided with one or more friction rollers 32 arranged in the axial direction thereof. The friction roller 32 is fixedly provided coaxially with the shaft body 31 so as to be rotatable following the shaft body 31. A loading position is formed between the friction rollers 32 on the shaft bodies 31 at two sides. When the cylinder 7 is placed, the outer peripheral surface of the cylinder 7 is in contact with the wheel surface of the friction roller 32, so that the cylinder 7 is supported. The first driving assembly is used for driving one or both of the two shafts 31 to rotate.

By using the clamping mechanism 4, the cylinder 7 positioned at the loading position is clamped and fixed. In this clamped state, a small gap is formed between the outer peripheral surface of the cylinder 7 and the wheel surface of the friction roller 32 so as to be away from the friction roller 32, so as to avoid the friction roller 32 interfering with the action of the clamping mechanism 4. The release states include a first release state and a second release state, wherein. In the first, released state, the cylinder 7 is axially movable on the clamping mechanism 4. When it is desired to spin the cylinder 7, the clamping mechanism 4 is switched to the second, undamped state so that the cylinder 7 falls onto the friction roller 32.

Specifically, the clamping mechanism 4 described above includes a clamping unit and a second drive assembly 5. The clamping units are arranged with at least two groups according to actual design requirements. The gripping unit comprises two finger members 41 arranged opposite each other and being able to approach or depart from each other. The two finger members 41 are arranged on opposite sides in the second direction of the loading position, and have opposite faces facing the outer peripheral surface of the cylinder 7 placed in the loading position. The second driving assembly 5 is used for driving the two finger members 41 toward and away from each other. Driven by the second driving unit 5, the two finger members 41 come close to each other to clamp and fix the cylinder 7 in the radial direction, forming the aforementioned clamped state. When the two finger members 41 are moved away from each other, the aforementioned released state is formed away from the cylinder 7. The opposite surfaces of the two finger members 41 are provided with arc-shaped grooves 411 adapted to the outer circumferential surface of the cylinder 7 to improve the stability of clamping.

The height difference is a small gap size. By means of this design, the cylinder 7 can be lifted off the friction roller 32 during clamping.

In the present embodiment, the aforementioned first and second released states are formed by controlling the distance between the two finger members 41 of the gripping unit. The distance between the two finger members 41 in the first released state is smaller than that in the second released state. In the first released state, the cylinder 7 falls into the lower half of the arc-shaped groove 411, and the cylinder 7 is driven by the external force to be movable in the center axis direction in the holding space formed by the two finger members 41.

The screw rod 51 extends in the second direction and is fixed to the housing 1 through a bearing block so as to be rotatable about its own central axis. The screw rod 51 is provided with a left-handed thread section and a right-handed thread section. One of the two finger members 41 is screwed to the left-hand thread section by a slider 52, and the other is screwed to the right-hand thread section by a slider 52. The guide rail is fixed to the seat body 1 and extends in the second direction. Both of the above-mentioned slide blocks 52 are slidably coupled to the guide rail. The second driving motor 53 is fixed to the housing 1 to drive the screw 51 to rotate in the forward and reverse directions.

In this embodiment, the second driving assembly 5 is disposed corresponding to each clamping unit, so that the second driving assembly 5 is used for independently driving each clamping unit to act, so as to achieve a clamping state and a releasing state. Or, the two screw rods 51 are connected in a transmission manner through transmission mechanisms (gear mechanisms, belt pulley mechanisms or cam mechanisms) with different transmission ratios, so as to drive each clamping unit to act in a linkage manner, so that each clamping unit acts in sequence.

In this embodiment, the cylinder rotary clamping device further includes a linear driving mechanism, which may be an electric push rod, an air cylinder, or the like. Which are arranged at one or both ends of the loading position for exerting a force in the horizontal direction on the cylinder for driving the cylinder 7 to move linearly in the lateral direction. When the cylinder 7 needs to be moved linearly transversely, the finger member close to one side of the linear driving mechanism is driven by the second driving assembly 5 to be opened to a first loosening state in advance, and the finger member far away from one side of the linear driving mechanism is driven by the second driving assembly 5 to be opened later, and the opening distance is smaller than the distance of the first loosening state, so that the whole stress of the cylinder 7 is concentrated on the finger member opened later, and the friction area of the cylinder 7 in the subsequent transverse linear movement is reduced.

In the aforementioned first released state, the linear drive mechanism pushes the cylinder 7 to move on the finger member in the direction of the central axis.

When the device is used, the cylindrical part is placed at the loading position in a horizontal posture so as to position the cylindrical part 7. By the driving of the rotation mechanism 3, the cylindrical body 7 part can realize the position adjustment in the circumferential direction by a self-rotation mode. The cylindrical part at the loading position can be fixed by the clamping of the clamping mechanism 4. In the case where it is desired to move the cylindrical part in the axial direction, the two finger members of one of the clamping units can be driven to move by the second driving assembly 5 to switch to the first unclamped state. And actuating the two finger members of the other set of gripping units to move to switch to the second released state. The cylindrical part is pushed by the linear driving mechanism so that the cylindrical part can be moved in the central axis direction on the holding mechanism 4. And switching each clamping unit into a second loosening state so as to drop the cylindrical part to the loading position. The combination of above-mentioned mode to can realize the centre gripping of cylinder 7 part in carrying the material position fixed and loosen fast, labour saving and time saving effectively satisfies the processing demand of cylinder 7 part. Through the cooperation use of rotating assembly 6 to can drive pedestal 1 and the relevant mechanism on it wholly rotate, realize the position adjustment of cylinder 7 part on a plurality of degrees of freedom, the practicality is strong.
