Description
Technical field
The utility model relates to a kind of frock be used to press-fiting engine air valve locking plate, is specifically a kind of frock sleeve that is used on this frock.
Background technology
The frock sleeve of prior art comprises the body of a hollow, one end of described body is provided with a plug, described plug is provided with the connecting hole that is connected for frock, and the other end of described body is provided with a ring block, also is provided with two observation panels on the wall thickness of described body.There is following defect in the frock sleeve of said structure in the use procedure of reality: when the manual press-loading engine air valve locking plate, first this frock sleeve is connected on frock by connecting hole, then ring block is propped up the valve seat of honour, again two valve split collets are put into the position between the valve seat of honour and valve stem, a seat of honour of then slowly down calming the anger, and with finger or other objects, prop up two valve split collets and adjust in real time its position, after two valve split collets put in place simultaneously, coming loose and taking out frock got final product., because air valve angle comparatively tilts and the reason such as valve spring power is larger, therefore in the assembling process of valve split collets, be difficult to guarantee that the position of valve split collets is accurate, thereby occur that locking plate blocks problem motionless or that locking plate launches.Therefore, the frock sleeve of prior art at the assembly difficulty of assembling during valve large and waste time and energy, efficiency of assembling is low.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defect of above prior art, provide a kind of can real-time ensuring valve split collets position in the valve assembling process frock sleeve accurately.
The technical solution of the utility model is, a kind of frock sleeve is provided, comprise a body, one end of described body is provided with a plug, described plug is provided with the connecting hole that is connected for frock, the other end of described body is provided with a ring block, be provided with in described body one can real-time ensuring valve split collets position in the valve assembling process stopping means in real time accurately.
Described real-time stopping means comprises the first stopping means that is slidably fitted in body and the second stopping means that is slidably fitted in the first stopping means, being provided with between described the first stopping means and plug resets uses the first spring, and being provided with between described the second stopping means and plug resets uses the second spring.
Described the first stopping means is an annular element, and an end of described annular element is provided with one and protrudes the outer annular protrusion of body, and described annular protrusion and ring block are slidably matched; One end of described the first spring and the other end of annular element offset, and the other end and the plug of described the first spring offset; The other end of described annular element is provided with the first groove.
Described the second stopping means comprises a conical head and a columnar member, and described columnar member is slidably fitted in the first groove; The end that one end of described columnar member and conical head area are larger is connected; The other end of described columnar member is provided with the second groove, and an end of described the second spring and the inner face of the second groove offset, and the other end and the plug of described the second spring offset.
After adopting above structure, the utility model compared with prior art, has the following advantages:
Be provided with a real-time stopping means in the body of the utility model frock sleeve, by this device, can remain that the position of valve split collets accurately puts in place in the assembling process of valve split collets, avoided locking plate to block motionless or locking plate and launched the appearance of problem.And the utility model frock sleeve, owing to manually not contacting valve split collets, is not tilted and the larger impact of valve spring power by air valve angle therefore.Therefore, the assembly difficulty of the utility model frock sleeve when the assembling valve is little and time saving and energy saving, efficiency of assembling is high.
As improvement, described plug is provided with a cylindricality locating part, and described cylindricality locating part is contained in the second spring, can effectively limit the radial position of the second spring by this cylindricality locating part, is conducive to improve the functional reliability of frock sleeve.
