Description
Technical field
The utility model relates to a kind of instrument of dismantling cylinder sleeve.
Background technology
In motor vehicle repair, replacing cylinder sleeve, bearing are an indispensable job, and the instrument of traditional dismounting cylinder sleeve needs to change pull head according to the cylinder diameter size in use, and the yielding fracture of pull head, wastes time and energy.
Summary of the invention
Technical problem to be solved in the utility model is: the instrument that overcomes traditional dismounting cylinder sleeve needs to change pull head according to the cylinder diameter size in use, and the yielding fracture of pull head, the drawback that wastes time and energy provides a kind of and can adapt to various cylinder diameter sizes, solid drawbench durable, easy to use.
The technical scheme that its technical problem that solves the utility model adopts is: comprise bracing frame, its design feature is to be connected with tapped sleeve on the bottom center position of described bracing frame, the top of bracing frame is provided with limiting plate, the inserting hole that leading screw passes the limiting plate middle part is connected with sleeve, on the leading screw between bracing frame and the limiting plate, be set with support spring, be evenly equipped with three groups of connecting plates that are hinged on the bracing frame in the radial direction at bracing frame, connecting plate is roughly concordant with the sleeve lower end, the position is hinged on the upper side at the middle part of each connecting plate bottom and pulling claw, be provided with pulling claw opening adjusting device between the top of pulling claw and the connecting plate, the contact-making surface of pulling claw top and sleeve outer wall is an arcuate structure, is strained by extension spring between the adjacent connecting plate.
Be evenly equipped with three length-adjustable spacing pillars in the radial direction at limiting plate.
The bottom of pulling claw is provided with the opening stopping means.
Described pulling claw opening adjusting device comprises the limiting plate that is fixed on the connecting plate, be provided with a hole at the top of pulling claw, limiting plate is provided with and the corresponding inserting hole in described silk hole, adjust to pass the inserting hole of screw mandrel from limiting plate and be connected on the described silk hole, on the screw mandrel between silk hole and the limiting plate, be set with holddown spring.
Bracing frame is " Y " shape, and three groups of connecting plates are hinged on described " Y " shape arm accordingly.
After adopting said structure,, therefore can adapt to the cylinder sleeve of dismantling different cylinder diameters because the opening scope of pulling claw is adjustable, simultaneously by pulling claw opening adjusting device, make the pull head and the cylinder sleeve relative fixed of pulling claw, limiting plate is placed the cylinder head outside, just rotatable leading screw, by pulling claw cylinder sleeve is slowly pulled out body, avoid injuring body, therefore easy to use, and have simple in structure, solid durable characteristics, based on same principle, this drawbench dismounting bearing is convenient equally.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:
