Background technology
Cylinder head is the main body of electromotor, and each cylinder and crankcase are connected by it, is to install piston, bent axle and the support framework of other part and accessories.Valve guide bushing, the guider of automotive engine valves, valve is play the guiding role, and makes the heat on valve stem pass to cylinder cover through valve guide bushing.Valve guide bushing is arranged in the guide hole of cylinder head.Owing to valve guide bushing exists leakage pressure, press-fits the problems such as rear size positions deviation, leakage pressure can cause scrapping of cylinder head, loss cost is big, press mounting dimension is defective can affect the firmness after pressing of valve guide pipe and guiding accuracy, when production line automation unit exception cannot produce simultaneously, interim replacement scheme is needed to deal with urgent production, therefore need a kind of easy press mounting tool of design, solve the specific demand of production scene, it is desirable to easy for operation, meet that to press-fit required precision and control of product quality stable.Current more company typically all uses simple plug directly to tap or without replacement scheme, owing to being that interference is press-fitted to joining guide hole in valve guide bushing and cylinder head, need after press-fiting to coordinate uniformly with in cylinder head to joining guide hole, to reach to fit firmly and axiality requirement, subsequent openings adds and meets requirement on machining accuracy man-hour, uses directly to tap and cannot ensure press mounting dimension and required precision, and easily pressure is partially, inconvenient operation, quality is unstable.
Summary of the invention
This utility model provide a kind of can be simple and convenient press-fit operation, Financial cost, improving product process quality control can be reduced again simultaneously, and possess applicable variety scope flexible operating wide, more preferable, it is ensured that a kind of simple valve guide pipe press mounting tool of cost, efficiency and quality；Solving and cannot ensure press mounting dimension and required precision present in prior art, easily pressure is partially, inconvenient operation, the technical problem that quality is unstable.
Above-mentioned technical problem is that of the present utility model is solved by following technical proposals: a kind of simple valve guide pipe press mounting tool, including press-fit bar and with press-fit the guide-localization set that bar coordinates, wherein, the center of guide-localization set offers through hole, the described bar that press-fits includes end and insertion section, described insertion section is insertion rod, insertion rod is inserted in through hole, end is connected to one end of through hole along with the insertion of insertion rod, and the other end at through hole is provided with the alignment concavity that the base end face with cylinder cover guide pipe hole coordinates.It is valve guide bushing can be put into it in through hole, then by press-fiting bar by the guide hole on pressing of valve guide pipe to cylinder head.Guide-localization set end offer alignment concavity, coordinate such that it is able to be first directed to positioning sleeve with cylinder cover guide pipe aperture step and base end face.And the through hole at guide-localization set center press-fits bar for guarantee and valve guide bushing coaxially positions.Valve guide bushing is inserted in guide-localization set, the most again the position being directed to positioning sleeve and cylinder head by the alignment concavity of guide-localization set end face is determined, press-fit in lid is inserted in through hole and press-fit in the guide hole that valve guide bushing enters in cylinder head, press-fit to end face and the guide-localization set end face laminating press-fiting bar, just complete and press-fit.Whole process is simple to operation, and axially polarization is good, and dimensional accuracy is high, and quality control is stable.
As preferably, described insertion rod and through hole are matched in clearance.Facilitate insertion rod freely-movable and ensure certain guidance quality and axiality in the through hole that guide-localization overlaps.
As preferably, the external peripheral surface of described end is provided with annular protrusion, and the external peripheral surface of annular protrusion is provided with annular knurl.Convenient manual crawl is with anti-skidding.
As preferably, one end of end is connected with insertion section, and the other end of end is sphere.Spherical design is used for making stress concentrate on center, conveniently press-fits.
As preferably, the external peripheral surface of described guide-localization set is provided with annular protrusion, and the external peripheral surface of annular protrusion is provided with annular knurl.
As preferably, the degree of depth that the movement travel in through hole of the described insertion rod is inserted in the guide hole of cylinder head with valve guide bushing is identical.The length of insertion rod is to determine with coordinating of guide hole according to valve guide bushing.Valve guide bushing is in guide-localization overlaps, the end face of valve guide bushing is encountered in the end of insertion rod, the movement travel of insertion rod refers to insertion rod and starts the distance that valve guide bushing is pressed in guide hole by stress, simultaneously after insertion rod motion puts in place and is namely pressed in guide hole by valve guide bushing, the end face that the end face of insertion rod end overlaps with guide-localization is concordant.
Therefore, the simple valve guide pipe press mounting tool of one of the present utility model possesses following advantage:
1. this cubing is simple to operate, compact conformation, simplification, novel in design, it is simple to a line operator uses.
2. controlled dimensions precision, job stability is high, and quality control is stable.
The most easy to operate, quick, Financial cost is low, applied widely.
Accompanying drawing explanation
Fig. 1 be a kind of simple valve guide pipe press mounting tool of prior art with the use of cross-sectional schematic.
Fig. 2 is the schematic diagram press-fiting bar in Fig. 1.
