Description
Technical field
The utility model relates to a kind of special-purpose accessory, a kind of instrument of diesel cylinder liner dismounting specifically.
Background technology
Cylinder sleeve is one of strength member on the diesel engine, and particularly its cylinder sleeve of the diesel engine of dry cylinder liner and cylinder body are interference fit, this thin-walled steel cylinder sleeve comparison difficulty of removing stage makeup and costume.Cylinder sleeve in the diesel engine usually needs dismounting in assembling or maintenance process, mainly contains following two kinds of situation: the first, and diesel engine in use because cylinder sleeve damages, needs repair and replacement; The second, in the diesel engine assembling process,, need unload cylinder sleeve owing to find the cylinder body defectiveness.In unloading process, propose to use common punching pin to knock and unload cylinder sleeve, the very difficulty that operates, and since firmly inhomogeneous, damage the sleeve port on the cylinder body easily or make the cylinder sleeve gross distortion, thereby the cylinder sleeve after the dismounting is scrapped, cause waste.
The utility model content
To use the sleeve port on the existing operation inconvenience of punching pin dismounting cylinder sleeve, the damage cylinder body and cause problem such as cylinder sleeve gross distortion in order to solve, the utility model provides a kind of convenience, diesel cylinder liner unloads holding tool reliably.
The purpose of the utility model is achieved through following technical scheme:
A kind of specific purpose tool that is used for diesel cylinder liner dismounting, include draw cover 1, backing pin 2, pull bar 3, rotary handle bearing 4, rotary handle 5 and handgrip 6;
Drawing and covering 1 outline is the round nullisomic with center symmetry chamfered edge, and circle nullisomic center laterally is provided with the long waist shaped hole, is provided with step at the circular arc place that justifies nullisomic;
Rotary handle bearing 4 is a weldment, and top is closing disk, and the bottom is the thin-walled long sleeve; Be provided with boss platform and centre bore in the closing disk upper surface;
Rotary handle bearing 4 closing disk central hole size are greater than pull bar 3 bar portion thread sizes;
Screwed hole size on the rotary handle 5 is identical with pull bar 3 bar portion thread sizes;
Draw and cover 1 and be installed in pull bar 3 end segment, pull bar 3 end segment are arranged on to draw and cover in 1 the long waist shaped hole.The interlude of backing pin 2 is installed in the pin-and-hole of pull bar 3 tail ends, and the backing pin 2 that stretches out outside pull bar 3 pin-and-holes part is horizontally set with drawing and covers 1 lower surface waist;
Draw the diameter dimension of topping bar that builds 1 circular arc place step than the little 0.1～0.2mm of cylinder sleeve internal diameter, the diameter dimension of getting out of a predicament or an embarrassing situation is than the little 0.3～0.4mm of cylinder sleeve outside dimension.
Rotary handle bearing 4 thin-walled long sleeve length dimensions are greater than the cylinder sleeve length dimension.
The technique effect of the utility model is embodied in following several aspect:
1. in unloading process, cylinder body oil sump face can need not to be sidelong towards held, and actual mechanical process is simple, convenient;
2. because this device adopt to rotate rotary handle drives to draw and cover 1 and spur the cylinder sleeve dismounting mode that moves up; Draw that to cover 1 step and cylinder sleeve contact area bigger; Make cylinder sleeve evenly stressed, thereby can not damage the sleeve port on the cylinder body, also can not cause cylinder to be with big distortion.
Description of drawings
Fig. 1 the utility model structural representation.
Fig. 2 is the right view of Fig. 1.
Among the figure: draw and cover 1, backing pin 2, pull bar 3, rotary handle bearing 4, rotary handle 5, handgrip 6, cylinder sleeve 7.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done further to describe through instance.
Embodiment:
A kind of specific purpose tool that is used for diesel cylinder liner dismounting, include draw cover 1, backing pin 2, pull bar 3, rotary handle bearing 4, rotary handle 5 and handgrip 6.
Drawing and covering 1 outline is the round nullisomic with center symmetry chamfered edge, and circle nullisomic center laterally is provided with the long waist shaped hole, is provided with step at the circular arc place that justifies nullisomic.Draw and cover 1 and be designed to the round nullisomic of symmetrical chamfered edge and laterally be provided with the long waist shaped hole, its objective is in order in use can conveniently to pass the cylinder trepanning in circle nullisomic center.
Rotary handle bearing 4 is a weldment, and top is closing disk, and the bottom is the thin-walled long sleeve; Be provided with boss platform and centre bore in the closing disk upper surface.
Rotary handle bearing 4 closing disk central hole size are greater than pull bar 3 bar portion thread sizes.
Screwed hole size on the rotary handle 5 is identical with pull bar 3 bar portion thread sizes.
Have identical screw thread on pull bar 3 and the rotary handle 5, its major function is through screw thread rotation, and cylinder sleeve is dismantled under the effect of uniform force.
Draw and cover 1 and be installed in pull bar 3 end segment, pull bar 3 end segment are arranged on to draw and cover in 1 the long waist shaped hole.The interlude of backing pin 2 is installed in the pin-and-hole of pull bar 3 tail ends, and the backing pin 2 that stretches out outside pull bar 3 pin-and-holes part is horizontally set with drawing and covers 1 lower surface waist.
Draw the diameter dimension of topping bar that builds 1 circular arc place step than the little 0.1～0.2mm of cylinder sleeve internal diameter, the diameter dimension of getting out of a predicament or an embarrassing situation is than the little 0.3～0.4mm of cylinder sleeve outside dimension.Draw and cover topping bar and get out of a predicament or an embarrassing situation and being the groundwork face of this device of 1 circular arc place step, so comparatively strict its dimensional requirement.
Rotary handle bearing 4 thin-walled long sleeve length dimensions are greater than the cylinder sleeve length dimension, its objective is to the cylinder sleeve after the dismounting to leave the space.
With cylinder body oil sump placed face down, hand-held handgrip 6 and rotary handle bearing 4, will be installed in earlier drawing on pull bar 3 end segment cover 1 (draw this moment cover 1 self gravity and be horizontally set with under the effect at the backing pin 2 of its lower surface waist, present tilting state.) interior until the lower surface of let-down to cylinder sleeve 7 by the cylinder cap faying face entering cylinder sleeve 7 of cylinder body, firmly go up handle then gently 6, make to draw and cover 1 the insertion cylinder sleeve endoporus of topping bar; The upper surface of getting out of a predicament or an embarrassing situation is against the cylinder sleeve lower surface, rotary handle bearing 4 is placed on the cylinder junction surface again, evenly firmly rotates rotary handle; Cylinder sleeve 7 at the uniform velocity rises in the sleeve; Cylinder sleeve is separated with cylinder body fully, neither can damage the sleeve port on the cylinder body, can not make cylinder sleeve 7 that big distortion is arranged again.
