Description
Technical field
The utility model relates to a kind of machine-building and maintenance field, and accessory is extracted in a kind of specifically special use that is used to extract the axis hole lining.
Background technology
Engine is when assembling and reprocessing, sometimes need the lining that is contained in the cylinder body balance axis hole is extracted, but this lining is extremely thin, and balance axis hole interference fit with cylinder body, extremely be difficult for pounding out, usually adopt crooked hook to stretch into and catch on lining in the cylinder body, oppositely knock hook with other weight again lining is taken out of.This method usually needs could extract lining for a long time, and since when knocking hook contact the dynamics inequality with cylinder body, be easy to damage cylinder body balance shaft hole inner wall, bring variety of issue.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, and provides a kind of axis hole lining simple in structure, that can extract lining fast and not damage shaft hole inner wall to extract accessory.
Technical scheme comprises interconnective loam cake, body and lower cover, described loam cake upper end is provided with the external screw thread that can be connected with pin removal, described push shaft center line vertically passes loam cake, body and lower cover, and the push shaft between described body and the lower cover is provided with flexible slide block mechanism.
Described flexible slide block mechanism comprises and is arranged on the pushing block on the push shaft between body and the lower cover, and is positioned at around the pushing block and the slide block that can contact with pushing block.
Described slide block is with the retracting spring circle outward.
Be with retracting spring on the push shaft between described body and the pushing block.
Be with adjusting pad on the push shaft between described body and the pushing block.
Described retracting spring is with the whole pad of downward modulation outward.
Described pushing block is up big and down small pyramidal structure, and described slide block also is the corresponding conical surface or inclined-plane with the pushing block contact-making surface.
Described body lower end edge radially has the groove that is used for to slider guide.
Described push shaft can axially promote, thrust can conduct on the push shaft flexible slide block mechanism, the pushing block of described flexible slide block mechanism contacts with slide block, pushing block conducts to slide block with power, slide block is stretched out, described pushing block is a pyramidal structure, with the slide block contact-making surface be the conical surface, respective slide also is the corresponding conical surface (or inclined-plane), the following thrust of push shaft makes pushing block promote slide block along the conical surface like this, make slide block also spreading radially when the lower cover direction moves vertically, the slide block around the described pushing block can evenly be provided with a plurality of as required, and is evenly stressed to guarantee lining.The retracting spring circle that is with on the described slide block is for when thrust disappears, and slide block can radially reclaim under the active force of retracting spring circle.Described retracting spring is in order to make push shaft when thrust disappears, can be to the travelling backwards of loam cake direction.Described upper and lower spacer has the restriction push shaft and moves down, thereby avoids slide block to extend radially out the effect of the long scuffing of distance shaft hole inner wall, and its thickness can extend radially out apart from appropriate design according to predetermined slide block.Described body lower end has the groove to the slide block correspondence, is used for to slider guide.
Beneficial effect:
1, simple in structure, convenient and practical, can be connected with pin removal to cooperate and extract lining.
2, utilize downward thrust to make push shaft promote slide block, slide block radially spreading stretches out, and can catch on lining by reverse side, and active force evenly can not damage the cylinder body shaft hole inner wall, and it is easy, time saving and energy saving to extract.
3, the utility model is extracted the axis hole of all size of lining for needs all applicable.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model user mode figure.
Fig. 3 is the utility model figure that pops.
Wherein, adjusting pad, 9-slide block, the 9.1-conical surface, the last adjusting pad of 10-, 11-balance axis hole lining, 12-engine cylinder-body, 13-pin removal, 14-screw under 1-loam cake, 1.1-external screw thread, 2-body, 2.1-groove, 3-lower cover, 4-push shaft, 5-taper pushing block, 6-retracting spring circle, 7-retracting spring, the 8-.
The specific embodiment
With reference to Fig. 1 and Fig. 3, loam cake 1, body 2 is connected through screw 14 (not shown in figure 1)s successively with lower cover 3 threes, the upper end of described loam cake 1 is provided with the external screw thread 1.1 that can be threaded and be connected with pin removal 13, body 2 is the cylinder in the balance axis hole lining 11 that can insert engine cylinder-body 12 just, push shaft 4 center line vertically passes loam cake 1 successively, body 2 and lower cover 3, on the push shaft 4 between body 2 and the lower cover 3, be provided with taper pushing block 5, establish retracting spring 7 on the push shaft 4 between taper pushing block 5 and the lower cover 3, evenly be furnished with four slide blocks 9 around the described taper pushing block 5, described slide block 9 is inboard to be the conical surface (or be inclined-plane) 9.1 corresponding with taper pushing block 5 with taper pushing block 5 contact-making surfaces, and slide block 9 outsides are with retracting spring circle 6.Described body 2 lower end edges radially have four grooves 2.1 for slide block 9 guiding, body 2 and taper pushing block 5 push shaft 4 on also be with adjusting pad 10, retracting spring 7 is outer to be with that downward modulation is whole fills up 8.
Be example explanation the utility model operation principle with the balance axis hole lining 11 of extracting engine cylinder-body 12 below:
Referring to Fig. 1 and Fig. 2, at first the utility model is inserted in the balance axis hole lining 11 of engine cylinder-body 12, body 2 just in time is enclosed within the balance axis hole lining 11, then pin removal 13 endoporus and loam cake 1 upper end screw thread are tightened, the endoporus of pin removal 13 promotes the effect that push shaft 4 overcomes retracting spring 7 and moves to left to lower cover 3 directions vertically in the rundown process, taper pushing block 5 on the push shaft 4 moves to left simultaneously, taper pushing block 5 utilizes its conical surface to promote effect that four slide blocks 9 overcome retracting spring circle 6 along groove 2.1 spreading radially, stretch out the slide block end, its distance of stretching out is by last adjusting pad 10 and following adjusting pad 8, stroke is slightly less than the thickness of balance axis hole lining 11, when extracting, slide block 9 can just in time tangle balance axis hole lining 11 and not damage shaft hole inner wall, then along the collision block that clashes into pin removal 13 in the other direction, at this moment four slide blocks 9 behind the spreading can clash into balance axis hole lining 11 vertically, utilize the impact of collision block just can take balance axis hole lining 11 out of so.After balance axis hole lining 11 was extracted, the screw thread that utilizes spanner that loam cake 1 and pin removal 13 are tightened again unclamped, and the active force that acts on push shaft 4 disappears, and push shaft 4 moves to right to loam cake 1 direction vertically, and slide block 9 reclaims, just can be balance axis hole lining 11 from body 2 taking-ups.
