Description
Technical field
The present invention relates to engine cylinder cover cubing, specifically, be a kind of cubing for detecting the head valve degree of depth.
Background technology
As shown in Figure 1, engine cylinder lid is provided with die cavity 9 and combustor 10, die cavity 9 and combustor 10 are by valve guide bushing 5, valve retainer 6 connects, inner conical surface and male cone (strobilus masculinus) it is divided at valve retainer 6, the tapering of male cone (strobilus masculinus) is more than the tapering of inner conical surface, valve retainer 6 is provided with datum line 6a (representing with thick line in figure), this datum line 6a is positioned at the end of valve retainer 6 male cone (strobilus masculinus), valve retainer 6 and valve realize line contact sealing by this datum line 6a, Fig. 2 show camshaft plug 7, known in conjunction with Fig. 1, camshaft plug 7 is arranged on the camshaft installing hole of cylinder cap. valve depth H refers to the distance to camshaft plug axis 7 of the datum line 6a on valve retainer 6.
Currently used valve depth inspection device to use in conjunction with dial gauge, valve depth inspection device is provided with the conical surface consistent with valve retainer male cone (strobilus masculinus) tapering, make cubing constitute face with valve retainer to contact, and by dial gauge beat, thus measuring the valve retainer datum line distance to cylinder cap right side, then converse valve depth value. The subject matter that this measuring method exists is: (1) cubing contacts with valve retainer face, and cylinder cap actually used time, valve retainer and valve are to realize linear contact lay by datum line, and whether the processing that this cubing cannot measure valve retainer datum line is qualified; (2) numerical value that cubing is measured is the valve retainer distance to cylinder cap right side, and valve depth value is the distance to camshaft plug axis of the datum line on valve retainer, calculates relatively cumbersome; (3) cubing to use in conjunction with dial gauge, and operate inconvenience, adds the complexity of measurement.
Summary of the invention
It is an object of the invention to provide a kind of easy to operate, measurement numerical value simple valve depth inspection device of conversion, valve depth value can not only be measured, moreover it is possible to whether the processing simultaneously detecting valve retainer datum line is qualified.
For reaching above-mentioned purpose, the valve depth inspection device of a kind of engine cylinder cover provided by the invention, including the grip part (1) being sequentially connected, conical section (2) and measurement bar (4), the diameter of described measurement bar (4) is less than or equal to the diameter of bore of valve guide bushing (5), the tapering of described conical section (2) is more than the male cone (strobilus masculinus) tapering of valve retainer (6), and conical section (2) and valve retainer (6) are at the upper linear contact lay of valve retainer datum line (6a), measure the distance between bar (4) end and camshaft plug (7) just to fill in for feeler gauge (8).
It is preferably, it is provided with transition shaft part (3), the diameter of described transition shaft part (3) diameter more than measurement bar (4), the diameter less than conical section (2) between described conical section (2) and measurement bar (4). Transition shaft part is set, and transition shaft part direct between conical section diameter and measure between shank diameter, guaranteeing that cubing can be inserted in cylinder cap under the premise of detection smoothly, as much as possible transition shaft part is set to long enough, diameter sufficiently large, to ensure the linearity that cubing is processed, reduce difficulty of processing.
The local of described grip part (1) excircle is scabbled, and forms a dozen identity planars (1a). The different valve shape of cylinder cap, size are different, even the two of same cylinder cap valves are also had any different, therefore each valve is required for custom-designed valve depth inspection device and detects, for avoiding obscuring between cubing, it is desirable to stamp mark on the measurement bar of cubing.
During measurement, first camshaft plug is installed in camshaft installing hole, again cubing is inserted in cylinder cap, when the conical section of cubing is with valve retainer linear contact lay on valve retainer datum line, feeler gauge is filled in the gap measured between boom end and camshaft plug, feeler gauge includes multi-thickness specification, the thickness of the radius+feeler gauge of valve depth H=camshaft plug+valve retainer datum line to measure boom end distance. The radius of camshaft plug, valve retainer datum line to measure the distance of boom end when design fixed, only need to read feeler gauge data, carrying out simple conversion and just can obtain the numerical value of air outlet valve depth H.
Beneficial effects of the present invention: simple in construction, operates with very convenient, measures numerical value and converts more simple, and while measuring valve depth value, whether the processing that can detect valve retainer datum line in the lump is qualified, kills two birds with one stone, and functional effect is notable.
