Abstract

The utility model discloses a hand tool for repairing, which is and expanding and withdrawing tool for axle sleeves. The expanding and withdrawing tool for axle sleeves is composed of a handle, a threaded rod, a support bracket, a working head, etc., wherein, the threaded rod whose tail part is connected with the handle is screwed into internal threads at the back part of the working head after passing through a nut, a shim, a bracket rack, and a sleeve tube in turn; the working head forms a tubular shape, the front end is slit, an internal opening of the front end forms a funnel shape, and a wrench clamp is arranged outside the back end. When the tool is used, the work efficiency is increased in multiples than that of the original technology, and the accuracy of a machine body is not affected.

Description

The axle sleeve expansion withdrawing tool

The utility model belongs to hand-operated tools, particularly relates to the axle sleeve expansion withdrawing tool of dismounting non through hole internal axle sleeve or lining.

At present maintenance industry in the dismounting non through hole axle sleeve or during lining, weldering one metallic rod sled commonly used draws, or drill through the hole and beat, or add ripping bar with clink.These methods can cause the reduction of axle sleeve gear precision, the designing requirement of destruction body, and operating efficiency is lower.

Task of the present utility model provides a kind of axle sleeve expansion withdrawing tool, and higher operating efficiency is arranged in repairing, and does not damage body.

Task is achieved by following scheme: afterbody is connected with the screw rod of handle, penetrates in the middle of bearing support, behind the sleeve pipe through the bearing support another side, is spun on the internal thread at working head rear portion.Said working head in a tubular form, its front end jag, the front end internal orifice is funnel-form, its rear end outside is shaped on the spanner card.Nut and pad are arranged between the handle of screw rod and bearing support.

The axle sleeve expansion withdrawing tool of making according to such scheme in use, choose working head and sleeve pipe with axle sleeve or the corresponding specifications and models of lining, screw rod is screwed in working head, again working head is fixed on the appropriate location (as oil groove) in the axle sleeve, with spanner spanner card, the while rotary handle, make screw front end before the working head hopper walls and then the degree that reaches the working head expanding and fuse with axle sleeve, load onto sleeve pipe, bearing support, pad, nut then successively, be wrenched nut this moment, because bearing support props up body, so axle sleeve can be pulled out easily.Use this instrument to significantly improve, and do not influence the precision of body than the operating efficiency of prior art.

Accompanying drawing is the schematic diagram of an embodiment in the utility model.

Embodiment is now described in conjunction with the accompanying drawings.

The axle sleeve expansion withdrawing tool is made up of handle 7, screw rod 2, bearing support 4, working head 1 etc.Afterbody is connected with the screw rod 2 of handle 7, penetrates from the centre of bearing support 4, behind the sleeve pipe 3 through bearing support 4 another sides, is spun on the internal thread at working head 1 rear portion.Said working head 1 in a tubular form, its front end jag, for example third-class bifurcated, or cross fork, this example is that cross is pitched.The internal orifice of front end is funnel-form.The outside, its rear end is shaped on the spanner card.Working head [1] will be through modifier treatment, to adapt to the variation of expanding and recovery.Corresponding with the axle sleeve specification, the axle sleeve expansion withdrawing tool forms a series.Said sleeve pipe 3, when effect is bearing support incompatibility body, the performance supporting functions, its front end has breach, uses for observing.
