Abstract
The utility model relates to a measuring device for the depth of an air valve pit of a piston, which is applied to measure the depth of a bottom face of the air valve pit at the top of the piston. The measuring device for the depth of the air valve pit of the piston is characterized in that a chassis is provided with feet and a measuring window; a meter frame is sleeved on a fixed shaft; the fixed shaft is vertical to the surface of the chassis and is connected with the chassis into a whole; the meter frame is provided with a sleeve hole; and a measuring meter penetrates through the sleeve hole and is fixed by an adjustable screw at a lateral side of the sleeve hole. The measuring device has the advantages that measuring points are on the same arc line and a standard horizontal plane is only determined by the chassis to calculate the depth of the air valve pit and judge whether the horizontal precision of the bottom face of the air valve pit is high or not; and the chassis is provided with the feet so that the measuring device is adapted to detection on the air valve pit of the piston with a complicated top surface structure.
Description
Technical field
The utility model relates to piston port and cheats depth measurement device, is applied to measure bottom surface, the valve hole degree of depth of top land.
Background technology
In recent years, the development of society, the going from strength to strength of automobile industry also improved the requirement of motor car engine performance thereupon.Safe, fuel-efficient, high-performance has become the direction of development of automobile.Wherein engine valve clearance directly affects the performance of motor car engine.The valve clearance is excessive: the inlet and outlet door is opened and to be lagged, and has shortened the intake and exhaust time, has reduced the Lift of valve, has changed normal port timing, makes engine not enough because of air inlet, and exhaust is clean and power descends.The valve clearance is too small: after engine operation, the part expanded by heating is pushed valve open, makes valve-closing not tight, causes gas leakage, and power descends, and makes the serious carbon distribution of sealing surfaces of valve or burn out, even the valve ramming piston.The tolerance clearance in valve and piston crown valve hole is the key link wherein, and this has just proposed high request to the depth dimensions that piston port is cheated.
The method of the detection piston port hole degree of depth is to adopt pit gauge at present.Use pit gauge once can only measure a point, measure the position with the just necessary mobile entire depth chi of the degree of depth of a plurality of points in hole, with the conversion measurement point.The measured value that so just can not guarantee these measurement points is the data with respect to same measuring basis surface level.And pit gauge utilizes a face to contact the datum water level that adopts when determining to measure with testee, and the precision of measuring on the piston of some mechanism like this is also not high enough.Therefore, need a kind of simple in structure, use and also measure easily the degree of depth that cubing is measured the piston port hole.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provides a kind of piston port simple in structure, easy to use to cheat depth measurement device.
The purpose of this utility model can notify following technical proposals to realize: piston port is cheated depth measurement device, it is characterized in that chassis band pin and measurement window; Dial framework is enclosed within on stationary shaft, and stationary shaft connects as one perpendicular to chassis surface and with the chassis; Dial framework band sleeve hole, meter passes sleeve hole and is fixed by the adjustable screw of sleeve hole side direction.
The utlity model has following advantage:
1, institute's measurement point of getting is on the same camber line, and datum water level is determined by the chassis is unique, asks for the valve hole degree of depth and judges whether horizontal accuracy is high for bottom surface, valve hole;
2, chassis band pin adapts to the piston port hole of detecting the top surface structure complexity.
Description of drawings
Accompanying drawing is the utility model structural representation.
In figure, 1 is the chassis, the 3rd, and pin, the 5th, dial framework, the 7th, stationary shaft, the 9th, meter, the 11st, sleeve, the 13rd, sounding rod, the 14th, sleeve hole, the 15th, measurement window, the 17th, adjustable screw.
Embodiment
The utility model is further described below in conjunction with accompanying drawing.Piston port hole depth measurement device is characterized in that chassis (1) band pin (3) and measurement window (15); Dial framework (5) is enclosed within on stationary shaft (7), and stationary shaft (7) connects as one perpendicular to chassis surface and with chassis (1); Dial framework (5) band sleeve hole (14), it is fixing by the adjustable screw (17) of sleeve hole side direction that meter (9) passes sleeve hole (14).
The utility model is placed on top land when using, compare to determine the degree of depth in valve hole at the reading of piston-top surface and valve bottom surface, hole by reading the meter gauge outfit, and come comparison and then judge that valve cheats whether level of bottom surface by the reading of getting the several measurement points in valve bottom surface, hole more.Should choose the position that to measure simultaneously end face and valve hole during placement.Rotate gauge outfit on dial framework (5) traverse measurement table (9) sounding rod (13) to piston-top surface, read the reading of meter, then the turning handle gauge outfit moves to bottom surface, piston port hole, read the reading of meter.And then compare by the reading of twice meter and can obtain the depth dimensions in piston port hole.Whether during level, measure the meter reading that does not exist together and compare on bottom surface, valve hole by gauge outfit as long as rotate dial framework judging bottom surface, same valve hole.In measuring process repeatedly, the sleeve (11) of meter (9) is inserted in sleeve hole (14) and is changed all the time by the fixing point of fixity of adjustable screw (17), and therefore, in whole measuring process, the measuring basis surface level is same, so just guaranteed the unitarity of data, comparability has been arranged.Judge bottom surface, valve hole whether the repeatedly measurement point of level at the same camber line, so can reflect that bottom surface, valve hole is with respect to the degree of tilt of measuring basis surface level.High precision is also just secure.Chassis band foot selects the space at foothold many at top land, and this bases oneself upon complicated top surface structure and can place ability stably with regard to having improved the utility model.
