The invention relates to a device for pressing and mounting a thin-wall sleeve, which can solve the problem that the thin-wall sleeve is difficult to press and
mount. The device comprises a press head, a basic shaft, a sliding sleeve, an upper floating retention sleeve, a lower floating retention sleeve, a
copper sleeve and the like. The upper end face of the basic shaft is provided with a
flange plate which is coaxially connected on a fixed fixture block by screws, an annular clamping groove of the fixed fixture block is clamped and hooped on a shaft journal at the upper part of the upper floating retention sleeve, the lower floating retention sleeve is coaxially positioned at the lower part of the upper floating retention sleeve, the upper floating retention sleeve and the lower floating retention sleeve are connected into a whole by the nuts of the retention sleeves, and the
copper sleeve is sleeved and arranged on the lower floating retention sleeve. The sliding sleeve is arranged in the upper floating retention sleeve and the lower floating retention sleeve, and the middle part of the external
diameter of the sliding sleeve is provided with a
piston ring; and the
lower half section of the sliding sleeve is provided with a
solid shaft, and the end face of the
solid shaft is provided with three centripetal tapered wedge T-shaped grooves which are uniformly distributed along a circumferential direction. The device has simple structure and convenient operation and can carry out pressing and mounting motions as long as the thin-wall sleeve is sleeved into the press head and a jack catch of a control button extends out, so that the parts of the thin-wall sleeve obtain higher pressing and mounting accuracy, and the effective guarantee is provided for enhancing the quality of a class of cylinder body.
