Abstract
The invention discloses a valve depth inspection device of an engine cylinder cover. The valve depth inspection device comprises a holding part (1), a cone section (2) and a measuring rod (4) which are sequentially connected. The diameter of the measuring rod (4) is smaller than or equal to the inner hole diameter of a valve shaft guide (5). The taper of the cone section (2) is larger than the outer conical surface taper of a valve retainer (6), and the cone section (2) and the valve retainer (6) are in line contact with each other on a valve retainer datum line (6a). The distance between the end of the measuring rod (4) and a cam shaft core rod (7) is right suitable for a plug gauge (8) to be plugged in. The valve depth inspection device of the engine cylinder cover is simple in structure, very convenient to use, even simpler in conversion of numerical measurements, capable of inspecting whether the valve retainer datum line is processed up to standard while measuring the valve depth and achieving two things at the same time, and remarkable in effect.
Description
Technical field
The present invention relates to the engine cylinder cover cubing, specifically, is a kind of cubing for detection of the head valve degree of depth.
Background technology
as shown in Figure 1, engine cylinder covers and is provided with die cavity 9 and firing chamber 10, die cavity 9 and firing chamber 10 are by valve guide bushing 5, valve retainer 6 is communicated with, be divided into inner conical surface and male cone (strobilus masculinus) at valve retainer 6, the tapering of male cone (strobilus masculinus) is greater than the tapering of inner conical surface, be provided with datum line 6a (representing with thick line in figure) on valve retainer 6, this datum line 6a is positioned at the end of valve retainer 6 male cone (strobilus masculinus)s, valve retainer 6 is realized line contact sealing with valve by this datum line 6a, Figure 2 shows that camshaft plug 7, in conjunction with Fig. 1 as can be known, camshaft plug 7 is arranged on the camshaft mounting hole of cylinder cap.The valve depth H refers to that datum line 6a on valve retainer 6 is to the distance of camshaft plug axis 7.
Use at present the valve depth check tool to use in conjunction with dial gauge, be provided with the conical surface consistent with valve retainer male cone (strobilus masculinus) tapering on the valve depth check tool, cubing is contacted with valve retainer formation face, and by the dial gauge beat, thereby measure the valve retainer datum line to the distance of cylinder cap right side, then converse the valve depth value.This measuring method Main Problems is: (1) cubing contacts with the valve retainer face, and during the actual use of cylinder cap, valve retainer is to realize that by datum line line contacts with valve, and whether this cubing can't be measured the processing of valve retainer datum line qualified; (2) numerical value measured of cubing be valve retainer to the distance of cylinder cap right side, the valve depth value be datum line on valve retainer to the distance of camshaft plug axis, calculate relative trouble; (3) cubing will be used in conjunction with dial gauge, and the inconvenience that operates has increased the complexity of measuring.
Summary of the invention
The object of the present invention is to provide a kind of easy to operate, simple valve depth check tool of measurement numerical value conversion, can not only measure the valve depth value, whether the processing that can also detect simultaneously the valve retainer datum line is qualified.
for reaching above-mentioned purpose, the valve depth check tool of a kind of engine cylinder cover provided by the invention, comprise the grip part (1) that is connected successively, conical section (2) and sounding rod (4), the diameter of described sounding rod (4) is less than or equal to the diameter of bore of valve guide bushing (5), the tapering of described conical section (2) is greater than the male cone (strobilus masculinus) tapering of valve retainer (6), and conical section (2) is reached the standard grade at valve retainer datum line (6a) with valve retainer (6) and is contacted, distance between sounding rod (4) end and camshaft plug (7) just in time supplies feeler gauge (8) to fill in.
Be preferably, be provided with transition shaft part (3) between described conical section (2) and sounding rod (4), the diameter of described transition shaft part (3) is greater than the diameter of sounding rod (4), less than the diameter of conical section (2).The transition shaft part is set, and the transition shaft part directly between conical section diameter and sounding rod diameter, guaranteeing that cubing can insert under the prerequisite that detects in cylinder cap smoothly, the transition shaft part is arranged to such an extent that long enough, diameter are enough large as much as possible, to guarantee the linearity of cubing processing, reduce difficulty of processing.
The part of described grip part (1) excircle is scabbled, and forms a dozen identity planars (1a).Valve shape, the size of different cylinder caps are different, even two valves of same cylinder cap are also had any different, therefore each valve needs custom-designed valve depth check tool to detect, and for avoiding obscuring between cubing, is preferably on the sounding rod of cubing and stamps sign.
During measurement, first the camshaft plug is installed in the camshaft mounting hole, again cubing is inserted in cylinder cap, reach the standard grade when contacting at the valve retainer datum line until the conical section of cubing and valve retainer, feeler gauge is filled in gap between sounding rod end and camshaft plug, feeler gauge comprises the multi-thickness specification, and the thickness of the radius+feeler gauge of valve depth H=camshaft plug+valve retainer datum line is to the distance of sounding rod end.The radius of camshaft plug, valve retainer datum line are fixed when the design to the distance of sounding rod end, only need read the feeler gauge data, carrying out simple the conversion and just can get the numerical value of air outlet valve depth H.
Beneficial effect of the present invention: simple in structure, operate very easy to usely, measure numerical value and convert more simply, when measuring the valve depth value, whether the processing that can detect in the lump the valve retainer datum line is qualified, kills two birds with one stone, and functional effect is remarkable.
