Clamping and expanding sleeve claw of sealing piece, automatic sleeving machine of sealing piece and sleeving method

Abstract

The invention belongs to the technical field of assembling of sealing elements, and particularly discloses a clamping and expanding sleeve claw of a sealing piece, an automatic sleeving machine of the sealing piece and a sleeving method. The clamping and expanding sleeve claw of the sealing piece comprises a bearing seat, a rotating assembly is rotationally connected to the lower portion of the bearing seat, the rotating assembly is connected with a plurality of sliding rods in a sliding mode in the radial direction, the ends, away from the rotating assembly, of the sliding rods are connected with pressing blocks in a one-to-one correspondence sliding mode, the pressing blocks and the corresponding sliding rods are combined to form clamping jaws, and the clamping jaws are distributed around the rotating assembly at intervals. According to the clamping and expanding sleeve claw of the sealing piece, the sealing piece is clamped and expanded through the clamping jaws, the thin sealing piece can be smoothly and accurately sleeved, the production efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of sealing member assembly, and in particular relates to a clamping and expanding collet of a sealing sheet, an automatic fitting machine and a fitting method of the sealing sheet. Background technique [0002] The sealing ring is used to seal the product, which can prevent the grease or oil inside the product from leaking out, and can also prevent the intrusion of splashing water or dust from the outside. For closed containers, it also has the effect of heat preservation and moisture resistance. [0003] Because the sealing ring has a certain degree of elasticity and resilience, it is necessary to expand the sealing ring before fitting the sealing ring, and then to fit it. For example, the Chinese invention patent specifically discloses a sealing ring socket device and its assembly equipment (application number: CN201910738651.3), through the cooperation of the piston, piston rod, and piston hole, the conne...

[0003] Because the sealing ring has a certain degree of elasticity and resilience, it is necessary to expand the sealing ring before fitting the sealing ring, and then to fit it. For example, the Chinese invention patent specifically discloses a sealing ring socket device and its assembly equipment (application number: CN201910738651.3), through the cooperation of the piston, piston rod, and piston hole, the connecting rod can slide in the piston hole of the connecting seat under the control of hydraulic pressure, thereby driving the connecting rod and the expansion needle to move, and the multiple expansion needles With cooperation, the expansion and contraction of the sealing ring is realized. Although the sleeve device can successfully realize the fitting of the sealing ring, it is only limited to the thicker sealing ring (such as the O-ring). For the thinner sealing sheet (because the sealing sheet Thin and easily deformed, resulting in very high requirements for the set), the socket device will no longer be applicable, and can only be set manually, which is not only low in efficiency, but also substandard in quality
