Description
Technical field
The utility model relates to a kind of automobile engine frock, and more particularly, it relates to a kind of valve oil seal disassembling fixture.
Background technology
In the automobile engine cylinder head assembling process; often meeting is defective because valve oil seal press-fits need extract refitting; valve oil seal cooperates tighter with valve guide bushing; need larger strength to extract; dismantle unified standard specific purpose tool and lack reliable capable valve oil seal in the existing technology; though each car enterprise self-developing some valve oil seals tear the instrument frock open, also have some defectives.Valve oil seal extracting tool if any a kind of pliers type, utilize the frictional force after jaw clamps oil-seal outer that valve oil seal is extracted, skid easily during with this tool operation, the dismounting valve oil seal is relatively required great effort, efficient is not high, and this instrument space of circling round in thin and dark tappet bore is very little in addition, and it is very inconvenient to operate, as will both scratching the tappet bore inner surface because of carelessness, scratch again the guide hole outer surface.Publication number is that the utility model of CN 2768985Y discloses a kind of stripping attachment of changing the shock absorber for front fork oil sealing when being exclusively used in service motorcycle on April 5th, 2006, sequentially be socketed to form by pull bar, spring, jaw, jaw fixed cover, fixed mounting base, three jaws are mutually 120 °, and consisting of flexible connection with the jaw fixed cover by pin, the head of jaw is provided with direction claw hook outwardly.The epimere of pull bar is the double inclined plane cone of yarn coil core shape, and its cone face is close to the inner edge of jaw all the time; The stage casing of pull bar is cylinder, and hypomere is for planing into symmetrically half square cylinder on plane, pull bar insert in the middle of three jaws and pass axis hole in the middle of jaw fixed cover, the fixed mounting base after become flexible connection with cam.During use, pull cam handle and just oil sealing can be pulled out.The utility model makes the dismounting oil sealing become very convenient, and this improves repair quality to alleviating maintenance personal's labour intensity, and it is all very favourable to reduce maintenance cost and burden for users.But this utility model structure is slightly aobvious complicated, and parts are more, are unfavorable for promoting.
The utility model content
For a difficult problem that solves in the production process or engine valve oil seal is not drawn out easily during maintenance, the utility model provides a kind of destructiveness valve oil seal disassembling fixture little, easy to use.
The technical solution of the utility model is: a kind of valve oil seal disassembling fixture, comprise sleeve, grab bar, pole and impact sleeve, the inwall of sleeve bottom has tapering, grabbing bar is connected with bush whorl in sleeve, grab the bar bottom and be provided with elasticity and divide claw, the interior button step that elasticity divides each pawl point of claw to be provided with projection, pole with grab bar and be connected, the pole top is installed with the top cap that expands, and impact sleeve is slidingly socketed on pole.Valve oil seal is after valve guide bushing compresses, the head of valve oil seal still has certain distance apart from the tappet bore bottom, and also there is the gap between valve oil seal external edge of head and tappet bore inwall, disassembling fixture designs for this design feature, during use, sleeve is stretched into tappet bore and entangles the head that valve oil seal exposes, bar is grabbed in turn, grab bar and can shift to valve oil seal, elasticity divides the interior button step on the claw pawl point to wedge from the gap of valve oil seal external edge of head and sleeve lining, because the squeezing action of sleeve bottom tapering, continue precession and grab bar, elasticity divides claw just radially to draw in, and interior button step inner edge can be stablized securely fastening valve oil seal outer rim, then hold impact sleeve and repeatedly upwards impact the top cap, utilize impulsive force that valve oil seal is tripped out.
As preferably, pole with grab between bar as being threaded.For guaranteeing that impact sleeve has enough displacement easily to produce larger impact velocity, pole has certain-length, and pole is threaded with grabbing bar, split and assembling easily, and part dimension can be processed littlely, and is easy to use and receive and keep.
As preferably, grabbing bar is hollow tubular structure, grab bar and be provided with internal thread, pole grab bar inner with grab bar and be threaded.Pole grab bar inner with grab bar and be connected, pole can be processed carefullyyer like this, the saving material.
As preferably, to grab the masthead end and be provided with flange, impact sleeve is located between top cap and the flange.Flange impact cover below impact sleeve forms spacing, and impact sleeve can rest on when not using on the position of fixing reposefully like this, the convenient use.
As preferably, circumferentially be provided with the ring of projection on the sleeve.Ring is projection on the side face of sleeve, can provide one to be easy to apply the vertically downward stress point of active force, and when being convenient to sleeve and stretching into tappet bore sleeve being exerted pressure makes it to be pressed onto fast the end.
As preferably, top cap and pole are one-body molded.The top cap directly withstand shocks cover impact and suffered impulsive force is delivered to pole, so top cap and strut piece must have enough degree of being connected firmly, integrated formed structure can provide desirable mechanical strength and useful life longevity energy.
The beneficial effects of the utility model are:
Rational in infrastructure, reliable operation.This valve oil seal disassembling fixture can adapt to the valve oil seal mounting structure, during work and the reliable fastening of valve oil seal, utilizing repeatedly impulsive force to change into direct pressure on top surface extracts valve oil seal, the power transmission efficiency is high in the course of work, loss is few, can not occur skidding, the situation such as dislocation, good working effect.
Easy to use, can increase work efficiency, reduce labour intensity.Use this valve oil seal disassembling fixture can be easily disposable finish to valve oil seal promptly, need not also when outwards pulling out valve oil seal to continue firmly only to need that multifrequency is time of short duration firmly can greatly reduce valve oil seal dismounting difficulty, time saving and energy saving.
