Background technology
At present, operationally, because the effect of high-temperature high-pressure fuel gas in cylinder, valve and valve base surface will wear and tear engine.High temperature makes valve and valve seat produce creep and plucking, and high pressure (cylinder pressure) makes cylinder cover workplace and air valve produce strain, and valve and valve seat produce micro-mistake and wear and tear.If valve seat smooth finish quality is bad, wearing and tearing can be made to aggravate, valve and valve base seal property decline, on the one hand carbon deposit is increased, unstable wear, on the other hand because air valve is not closed completely, combustion gas washout valve seating face, valve face forms the vestige such as " pit ", " pit " " groove ".So the valve face crudy of inlet and outlet valve seat just and important.In general, engine air valve base, its seat surface roughness, dimensional accuracy, form and position tolerance all require very high, and its 120 ° of conical surfaces are because its length is very short, cannot with the measurement of its diameter dimension precision of traditional method Measurement accuracy, tapering precision and roughness and form and position tolerance.
Traditional tapering detects and generally checks with omnipotent vernier protractor, angular templet, cone gage.And higher for precision, and length is very short, the detection on the inclined-plane that angle requirement is high detects then very inaccurate by above several way.Situation shown in the upper figure, the length of its valve face is only 4.03, and accuracy requirement is high.
Utility model content
Goal of the invention of the present utility model is the shortcoming overcoming prior art, provides one engine air valve base valve face gauge accurately, in order to overcome the above problems.
It is as follows that the utility model solves the problems of the technologies described above taked technical scheme:
A kind of engine air valve base valve face gauge, comprise: the feeler gauge (1) identical with tested valve seat seat surface conical surface ostensible angle, be enclosed within on the measuring unit of its supporter clearance fit (2), feeler gauge (1) is coaxial with measuring unit (2), one register pin (3) is arranged in the bar portion of feeler gauge, be interference fit with bar portion, the center line of its center line and feeler gauge is in 90 °.
Further, preferably, described feeler gauge (1) and measuring unit (2) right alignment are within 0.004.
After the utility model takes such scheme, the diameter dimension of valve seat seat surface can be detected, the function that the cone angle of circular cone endoporus, form and position tolerance, roughness etc. require can be detected again.
Other features and advantages of the utility model will be set forth in the following description, and, partly become apparent from instructions, or understand by implementing the utility model.The purpose of this utility model and other advantages realize by structure specifically noted in write instructions, claims and accompanying drawing and obtain.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail, to make above-mentioned advantage of the present utility model definitely.
