Good effect of the present utility model is: provide a kind of simple in structure, easily manufactured, use simple, time saving and energy saving, avoid cylinder jacket and cylinder block impaired, and can realize the installation of cylinder jacket, have simultaneously solid durable, detachable easily-storied cylinder jacket dismantling device.
The technical solution of the utility model is: a kind of special-purpose dismantling device of cylinder jacket of diesel engine, this instrument comprise turning handle, horizontal stand, inside and outside reverse pair of thread bush, work screw mandrel, upper arm-tie and lower pulling plate; Upper arm-tie contacts with the cylinder jacket lower limb, the locating hole that the work screw mandrel passes arm-tie central authorities is threaded with inside and outside reverse pair of thread bush, the outer screw thread of inside and outside oppositely two thread bush is connected with the nut of horizontal stand central authorities, and inside and outside reverse pair of thread bush square post topmost coordinates with turning handle and is connected.
In the utility model, upper and lower arm-tie both sides are processed with the step that coordinates with cylinder jacket, and upper and lower arm-tie is provided with the chamfering of eccentric gathering sill and centralized positioning, the space of inclination can be arranged and guarantee work screw mandrel positioning and guiding to guarantee arm-tie.
In the utility model, the central authorities of horizontal stand are hexagonal pit, in order to place and hold-down nut, there is the strip groove that coordinates with bolt of cylinder head on both sides.
The utlity model has simple in structurely, easily manufactured, use simply, time saving and energy saving, and can realize the installation of cylinder jacket, have simultaneously solid durable, the advantage of foldable for storage.Can be used for the cylinder jacket dismounting of various internal combustion engines.

The specific embodiment
The cylinder jacket of diesel engine dismantling device that the utility model provides mainly is comprised of turning handle 1, horizontal stand 2, inside and outside reverse pair of thread bush 4, work screw mandrel 6, lower pulling plate 7-1 and upper arm-tie 7-2.
Please refer to shown in Figure 1, work screw mandrel 6 is fixed in inside and outside oppositely two thread bush 4 by screw thread, inside and outside oppositely two thread bush 4 relies on external screw thread to be fixed on the nut of horizontal stand 2, and work screw mandrel 6 is fixed on the lower limb of cylinder jacket 5 by the positioning through hole in the middle of upper arm-tie 7-2.
Described turning handle 1 is common augmentor, can buy in the market.
Described horizontal stand 2, lower pulling plate 7-1 and upper arm-tie 7-2 are that general steel plate is processed into.
When using this instrument dismounting cylinder jacket, upper arm-tie 7-2 summary low dip is put into makes it be stuck in the lower limb of cylinder jacket away from gathering sill one end in cylinder jacket, upwards pull work screw mandrel 6, work screw mandrel 6 the effect lower slider of gathering sill in the positioning through hole of arm-tie 7-2, then horizontal stand 2 is fixed on bolt of cylinder head 3, rotating turning handle 1 can disassemble cylinder jacket from cylinder block.
When using this instrument that cylinder jacket is installed, first cylinder jacket 5 is placed in cylinder block until can not down place, at this moment, lower pulling plate 7-1 summary low dip is put into makes it be stuck in the lower limb of cylinder block away from gathering sill one end in cylinder block, upwards pull work screw mandrel 6, work screw mandrel 6 in the effect lower slider of gathering sill in the positioning through hole of lower pulling plate 7-1, then upper arm-tie 7-2 is stuck in the top edge of cylinder jacket, then rotates turning handle 1 until cylinder jacket 5 top edges get final product with the cylinder block top edge is concordant.
Sketch the course of work of the present utility model below in conjunction with accompanying drawing.
