As shown in the figure, the supporting part and the clamping parts are integrally formed, wherein one clamping part is completely connected to the supporting part and is positioned on the symmetrical center point of the supporting part, and the other two clamping parts are connected to the two semicircular ends of the supporting part, and obviously, only part of the clamping parts are connected. The supporting part below is designed into a semicircle, so that the purpose is to expose the motion working conditions of the double-acting installation component and the piston rod, and different cylinders and power components can be replaced at any time. The clamping groove and the clamping block are used for being matched with the single-action clamping jaw mounting assembly.
The three clamping parts 102 are provided with single-action clamping jaw mounting assemblies 2; the single-action clamping jaw mounting assembly 2 comprises a sliding block 201 and a single-action clamping jaw 202 fixedly arranged on the sliding block 201; the sliding block 201 is embedded in the clamping block 104, an abutting block 203 is arranged at the bottom of the sliding block 201, a spring 204 is arranged in the clamping groove 103, and one end of the spring 204 abuts against the abutting block 203, so that the spring 204 pushes the single-action clamping jaw mounting assembly 2.
The sliding block is limited by the clamping block and moves along the radial direction. The sliding block pushes the abutting block through the spring to realize the movement towards the circle center direction.
A double-acting clamping jaw mounting assembly 3 is arranged between every two clamping parts 102, and is positioned at the same horizontal height with the single-acting clamping jaw mounting assembly 2 when the double-acting clamping jaw mounting assembly 3 moves to the topmost end; the double-acting clamping jaw mounting assembly 3 comprises a central sliding block 301, a double-acting sliding block assembly 302 and double-acting clamping jaws 303; the central sliding block 301 is provided with three sliding strips 3011 with included angles of 120 degrees outwards along the radius; the three sliding strips 3011 are respectively located between the two clamping portions 102, the double-acting sliding block assemblies 302 are arranged on the sliding strips 3011, and each double-acting sliding block 3023 is provided with a double-acting clamping jaw 303.
The central slide block and the slide bar form a structure similar to a three-fork star, are placed in the mounting block and move up and down. The sliding bar is provided with a double-acting sliding block component which is used for realizing horizontal movement along the radial direction and vertical movement.
The double-acting slide block assembly 302 comprises a double-acting spring 3021, a double-acting abutment block 3022 and a double-acting slide block 3023; the double-acting sliding block 3023 is positioned on the sliding bar 3011 to do reciprocating motion; the lower surface of the double-acting slide block 3023 is provided with a double-acting abutment block 3022, and the double-acting spring 3021 is provided on the slide 3011 and abuts against the double-acting abutment block 3022.

The lower end of the mounting block 1 is connected to a chassis 5 through a connecting column 4; the center of the mounting block 1 is provided with a through hole for the piston rod 6 to move, the end part of the piston rod 6 is provided with a power assembly 7, and the power assembly 7 is fixedly arranged on the chassis 5; the bottom of the double-acting clamping jaw mounting assembly 2 is connected with an air cylinder 8, and the air cylinder 8 is fixedly arranged on the chassis 5.
The piston rod is driven by the power assembly to move up and down in the through hole, the single-acting clamping jaw and the double-acting clamping jaw are driven by the spring and the double-acting spring to move towards the circle center, and when the piston rod moves upwards, the single-acting clamping jaw and the double-acting clamping jaw are propped open towards the outside.
Further, a sliding shaft 9 is arranged below the sliding strip 3011, the sliding shaft 9 penetrates through the mounting block 1, and a limiting flange 901 is arranged at the end part of the sliding shaft 9. The sliding bar is limited, and the sliding bar is prevented from moving upwards excessively, so that the parts are damaged.
The top of the piston rod is in a truncated cone shape. The top of the piston rod needs to have an inclined surface so that the single-acting jaw and the double-acting jaw are pushed apart step by step.
It is worth mentioning that the working end face structures of the single-acting clamping jaw and the double-acting clamping jaw are the same, and the single-acting clamping jaw and the double-acting clamping jaw are provided with a raised head, the raised heads of the three single-acting clamping jaw and the three double-acting clamping jaw are in an annular array, and the O-shaped ring is sleeved on the raised head. The piston rod moves upwards, the single-acting clamping jaw and the double-acting clamping jaw are outwards opened, and the O-shaped ring is further unfolded. After all clamping jaws move to the position for installing the O-shaped ring, the air cylinders of the double-acting clamping jaw seat retract to drive the three double-acting clamping jaws to move downwards, and as the three double-acting clamping jaw installing blocks are provided with curved surfaces matched with the cylindrical surfaces of the piston rods, the clamping jaws of the group can still keep an open state after moving downwards, and at the moment, the O-shaped ring contacted with the clamping jaws of the group is separated from the clamping jaws and is attached in the O-shaped ring installing groove. The clamping jaw is withdrawn from the O-ring mounting position, and the O-ring is retained in the O-ring mounting groove when the clamping jaw is withdrawn, since three positions of the O-ring are previously located in the O-ring mounting groove, and thus the O-ring mounting is completed. When the O-shaped ring in the workpiece is installed, the clamping jaw is only required to be replaced, and the action sequence of the clamping jaw is changed.
The O-shaped ring in the workpiece is installed, the single-acting clamping jaw and the double-acting clamping jaw firstly prop open the O-shaped ring, the piston rod contracts, the single-acting clamping jaw firstly contracts and is separated from the O-shaped ring, in addition, the double-acting clamping jaw and the piston rod synchronously contract, so that the double-acting clamping jaw always keeps an open state, then the double-acting clamping jaw is pushed upwards by the air cylinder, the double-acting clamping jaw contracts and is completely separated from the O-shaped ring, the O-shaped ring is left in the workpiece, and the convex head is not the length of the drawing, so that the length can be adjusted according to different workpieces.
It should be understood that the foregoing examples of the present invention are provided merely for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention, and that various other changes and modifications may be made therein by one skilled in the art without departing from the spirit and scope of the present invention as defined by the appended claims.
