The first embodiment is as follows:

this O type circle assembly devices includes:

the chassis 100, the center of the chassis 100 is provided with a through hole 110;

the claw 200 comprises a back surface 210, a front surface 220 and a side surface 230, the claw 200 is wedge-shaped, the width of the claw is gradually reduced from top to bottom, the claw 200 is arranged at the edge of the chassis 100, the back surface 210 faces the center of the chassis 100, and the claw 200 is movably connected between the back surface 210 and the chassis 100;

the push rod 300, the push rod 300 passes through the through hole 110 in the center of the chassis 100, the front end of the push rod 300 is provided with a connecting disc 310, the connecting disc 310 is movably connected with a connecting rod 320, the connecting rod 320 is matched with the claw piece 200 and is movably connected with a connecting head 211 in the middle of the back 210, and the rear end of the push rod 300 is connected with a power device 330.

In the prior art, a workpiece is usually manually or directly extruded into an O-shaped ring by a tool, the O-shaped ring is easily damaged in the process of opening the O-shaped ring by the workpiece, so that the sealing effect is reduced, the O-shaped ring is easily installed in an improper position, the O-shaped ring needs to be detached and reassembled, the assembling efficiency is low, and the labor intensity of workers is high.

The O-shaped ring is unfolded by the claw pieces and sleeved with the workpiece. In specific implementation, the jaw 200 is closed, the push rod 300 is in a high position, the O-ring is sleeved on the lower end of the upper jaw 200, the power device 330 works, wherein the power device 330 mostly adopts an air cylinder to push the push rod 300 to move to a low position, the push rod 300 drives the connecting rod 320 through the connecting disc 310, the connecting rod 320 is linked to open the closed jaw 200, so that the jaw 200 opens the O-ring, the front surface 220 of the jaw 200 is a vertical surface, the O-ring cannot be separated from the jaw 200, after the O-ring is opened, the part of the workpiece needing to be assembled with the O-ring is placed into the inner side of the lower end of the jaw 200 and is flush with the lower end of the jaw 200, then the power device 330 returns, the push rod 300 returns to the high position, the jaw 200 is closed again and contacts the workpiece from the back surface 210, the front surface of the jaw 200 is an inclined plane, the O-ring moves downward due to the elastic deformation recovery of the O-ring, until the separated claw pieces 200 are transited to the workpiece, the O-shaped ring is assembled on the workpiece, and finally the workpiece is taken out from between the claw pieces 200.

The O-shaped ring has the advantages that the contact area of the claw piece 200 and the O-shaped ring is large, the stress on the O-shaped ring is dispersed, and the O-shaped ring is less damaged compared with the existing O-shaped ring which is opened by a four-claw mechanism; the workpiece can extend into the space between the claw pieces 200, so that the position needing to be assembled, such as a sealing groove, can be just aligned to the lower edge of the claw pieces 200, the position of the O-shaped ring can be accurately assembled, manual adjustment is not needed, and the like, and the production efficiency is improved.

Example two:

the difference between the second embodiment and the first embodiment is that the chassis 100 is octagonal, and each side of the chassis is provided with a claw piece 200.

Specifically, compared with a mechanism for expanding the O-shaped ring by using the four-corner claw in the prior art, the eight claw pieces 220 are arranged to enable the stress of the claw piece 200 on the O-shaped ring to be more dispersed, so that the O-shaped ring is protected from being damaged, the expanded O-shaped ring is closer to a complete circle shape and can move on the claw piece 200 more easily, and the chassis 100 is octagonal and can reduce interference to the claw piece 200 in operation.

Example three:

the difference between the third embodiment and the first embodiment is that the base plate 100 and the claw piece 200 are movably connected through a hinge 120.

Specifically, the hinge 120 is very simple to mount and dismount, the claw piece 200 can be quickly and conveniently dismounted and replaced, the working efficiency is improved, and the hinge 120 is simple in structure and not prone to mechanical failure.

Example four:

the difference between the first embodiment and the fourth embodiment is that the side 230 is shown as a trapezoid with a gradually decreasing width from top to bottom.

Specifically, when the jaw 200 is spread, the front surface 220 is a vertical surface, and when the jaw 200 is closed to contact a workpiece, the front surface 220 is inclined inward, and the back surface 210 is changed into a vertical surface, so that a larger contact surface can be formed between the front surface 220 and the back surface and the surface of the workpiece, and the workpiece cannot shake between the jaw 200, which causes deviation of the assembly position of the O-ring.

Example five:

the difference between the fifth embodiment and the first embodiment is that the front surface 220 is an arc-shaped surface.

Specifically, the arc-shaped front face 220 can be better matched with the shape of the O-shaped ring, so that the O-shaped ring is prevented from generating stress concentration at a corner and damaging the O-shaped ring.

Example six:

the difference between the sixth embodiment and the first embodiment is that a slot 221 is formed at the lower end of the front surface 220.

Specifically, the arrangement of the clamping groove 221 enables the O-shaped ring to be clamped into the clamping groove 221 in the process of being propped open by the claw piece 200, the O-shaped ring cannot be separated from the claw piece 200 due to the recovery of the elastic deformation of the O-shaped ring, the propping failure of the O-shaped ring is avoided, the size of the clamping groove 221 can be designed in the process that the claw piece 200 is closed to contact with a workpiece, the O-shaped ring is enabled to be separated from the clamping groove 221 through the elastic deformation recovery when a certain angle is reached, and the workpiece is smoothly assembled.

Example seven:

the seventh embodiment is different from the first embodiment in that the lower end of the back surface 210 is provided with a slip-preventing piece 212.

Specifically, the anti-slip sheet 212 can enable the claw piece 200 to have larger friction force when contacting a workpiece, so that the relative positions of the claw piece 200 and the workpiece are more fixed in the O-shaped ring assembling process, and the assembling accuracy of the O-shaped ring is ensured.

What has been described herein is merely a preferred embodiment of the utility model, and the scope of the utility model is not limited thereto. Modifications, additions, or substitutions by those skilled in the art to the specific embodiments described herein are intended to be within the scope of the utility model.
