Abstract
The invention relates to a valve clearance checker. The valve clearance checker is composed of a measuring tool and a standard clearance gauge; one end of the measuring tool is a handle; the other end of the measuring tool is a wedge-shaped work area; the upper plane of the wedge-shaped work area is a work slope; two side surfaces of the wedge-shaped work area are parallel to each other and are perpendicular to the lower plane of the wedge-shaped work area; a side surface of the measuring tool is provided with a maximum clearance carved line and a minimum clearance carved line; the heights of the maximum clearance carved line and the minimum clearance carved line are respectively corresponding to a maximum valve clearance and a minimum valve clearance of a measure valve; the standard clearance gauge is provided with a parallel slit; and the minimum width of the parallel slit is the standard clearance of the measure valve. The valve clearance checker has the advantages of simple operation, intuitiveness and high reliability. The standard clearance gauge arranged on the valve clearance checker of the invention can realize high accuracy of a checking and measuring tool, and can be also applied to daily training of operators.
Description
Technical field:
The present invention relates to field of internal combustion engine, a kind of valve clearance detector, particularly relate to a kind of instrument adopting wedge shape inspection, adjustment valve clearance, particularly a kind of instrument utilizing scale mark scope to carry out valve clearance inspection, adjustment.
Background technology:
The efficiency, serviceable life, operating mode etc. of the size combustion motor of valve clearance have a direct impact, because adjustment improper caused fault in valve clearance is also more, current inspection valve clearance is mainly undertaken by thickness gauge, in measuring process, by the kinetic friction force of thickness gauge, operator judges that whether gap is correct, the criterion of this method, from the subjective consciousness of operator, is made mistakes than being easier in practice.
Summary of the invention:
What the present invention solved is the indeterminable problem in existing valve clearance, provides a kind of verification, training method simultaneously.
For solving the problems of the technologies described above, the invention provides a kind of valve clearance detector, it is made up of survey instrument and standard room gap gauge, one end of survey instrument described in it is handle, the other end is wedge shape workspace, the upper plane of described wedge shape workspace is inclined working, and two sides are parallel to each other and perpendicular to lower plane, described standard room gap gauge have a parallel seam.
Optionally, described inclined working is in same plane and this inclined-plane and the Plane intersects simultaneously perpendicular to described lower plane, side, and the intersection of gained is parallel to lower plane.
Optionally, the side of described survey instrument is provided with maximal clearance groove and minimum clearance groove.
Optionally, the groove height of described maximal clearance groove and minimum clearance groove distinguishes the maximum valve clearance of corresponding measured valve and minimum valve clearance.
Optionally, the minimum widith of described parallel seam is the standard clearance of measured valve
The present invention and prior art compare, and the feature that the measurement of the present invention to valve clearance has simply, directly perceived, error is controlled, the present invention adopts standard room gap gauge also can play training effect while the accuracy of check measurement instrument.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
Fig. 1 is survey instrument structural representation of the present invention.
Fig. 2 is the side view of survey instrument of the present invention.
Fig. 3 is standard room of the present invention gap gauge front elevation.
Fig. 4 is standard room of the present invention gap gauge left view.
Embodiment:
Structure of the present invention as shown in Figure 1, Figure 2, Figure 3, Figure 4, it is made up of survey instrument and standard room gap gauge 5, one end of described survey instrument is handle 2, the other end is wedge shape workspace, the upper plane of described wedge shape workspace is inclined working 1, two sides 8 are parallel to each other and perpendicular to lower plane 7, described standard room gap gauge 5 have a parallel seam 6.
Further, described inclined working 1 is in same plane and this inclined-plane 1 and the Plane intersects simultaneously perpendicular to described lower plane 7, side 8, and the intersection of gained is parallel to lower plane 7.
Further, the side 8 of described survey instrument is provided with maximal clearance groove 3 and minimum clearance groove 4.
Further, the groove height of described maximal clearance groove 3 and minimum clearance groove 4 distinguishes the maximum valve clearance of corresponding measured valve and minimum valve clearance.
Further, the minimum widith of described parallel seam 6 is the standard clearance of measured valve.
Principle of work of the present invention:
In measurement, to guarantee before adjustment that valve is in buttoned-up status, rocking arm is in can measure valve clearance state, survey instrument is inserted according to the method for regulation the position measuring valve clearance, when exerting oneself suitable, if valve center line illustrates that valve clearance is normal between maximal clearance groove and minimum clearance groove, need not adjust, otherwise, if valve center line is not between maximal clearance groove and minimum clearance groove, need in the outside of maximal clearance groove to reduce valve clearance, need in the outside of minimum clearance groove to increase valve clearance, in measuring process, valve center line is relevant with the size of exerting oneself of operator with the relative position of survey instrument groove, firmly size can obtain by repeatedly coordinating between survey instrument and standard room gap gauge exercise, survey instrument accuracy is also tested by standard clearance rule.
Above-described be only the preferred embodiment of the present invention, and adopt wedge tool to measure valve clearance as long as should be understood that, other version is also in protection scope of the present invention.
