Description
Technical field
The utility model relates to the measurement measurer, specifically is a kind of depth survey measurer of high-power marine low speed diesel engine cylinder head fuel oil valve opening.
Background technology
As shown in Figure 1 and Figure 2, high-power marine low speed diesel engine cylinder head fuel oil valve opening 1 comprises seal section 1.1, free section 1.2 successively, gos deep into section 1.3, conical section 1.4, atomizer construction section 1.5; The bottom center of described conical section 1.4 is to apart from d strict tolerance being arranged between the center, upper end of seal section 1.1.But because conical section 1.4 is a taper surface, and there is certain angle on the last plane of fuel oil valve opening 1 and cylinder head, can't find reference point or the reference field of measuring two ends like this, and the d that adjusts the distance there is not special measuring tool to measure, so can't check whether meet the drawing requirement after machining yet.
The utility model content
The technical problems to be solved in the utility model is that the depth survey measurer of a kind of bottom center of energy measurement fuel oil valve opening conical section to the high-power marine low speed diesel engine cylinder head fuel oil valve opening of the distance between the center, upper end of seal section is provided.
The technical solution of the utility model is, a kind of depth survey measurer with high-power marine low speed diesel engine cylinder head fuel oil valve opening of following structure is provided, and comprises measuring, and described measuring is provided with first measuring section, second measuring section, the 3rd measuring section successively; The shape of described first measuring section is identical with the shape of the seal section of fuel oil valve opening, the angle of the last plane of described first measuring section and the axis of measuring equals the angle of the axis of cylinder cover upper planar surface and fuel oil valve opening, and the external diameter of described first measuring section is less than the internal diameter of seal section; The shape of described the 3rd measuring section is identical with the shape of the conical section of fuel oil valve opening, and the external diameter of described the 3rd measuring section is less than the internal diameter of corresponding conical section.
After adopting above structure, the utility model compared with prior art, have the following advantages: because that the shape of the shape of described first measuring section and the seal section of fuel oil valve opening is identical is identical with the shape of the conical section of the shape of described the 3rd measuring section and fuel oil valve opening, the measurer physical efficiency is put in the fuel oil valve opening during measurement, the 3rd measuring section and conical section are fitted, the bottom of the bottom of the 3rd measuring section and conical section maintains an equal level simultaneously, and just the datum mark of the bottom center of conical section can be used as in the bottom of the 3rd measuring section; Again because the angle of the axis of the last plane of described first measuring section and measuring equals the angle of the axis of cylinder cover upper planar surface and fuel oil valve opening, the datum mark at the center, upper end of seal section can be used as in the last plane of just described first measuring section, promptly vertical range observation is changed in oblique range observation.During measurement, only need the last plane of measurement first measuring section and the difference of cylinder cover upper planar surface just can measure the bottom center of conical section to the distance between the center, upper end of seal section.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 3, Figure 4, the depth survey measurer of high-power marine low speed diesel engine cylinder head fuel oil valve opening of the present utility model comprises measuring 2, and described measuring 2 is provided with first measuring section 2.1, second measuring section 2.2, the 3rd measuring section 2.3 successively; The shape of described first measuring section 2.1 is identical with the shape of the seal section 1.1 of fuel oil valve opening 1, and the angle of the last plane of described first measuring section 2.1 and the axis of measuring 2 equals the angle of the axis of cylinder cover upper planar surface and fuel oil valve opening 1; The external diameter of described first measuring section 2.1 that is to say described first measuring section 2.1 and seal section 1.1 clearance fit when measuring less than the internal diameter of seal section 1.1.The shape of the conical section 1.4 of the shape of described the 3rd measuring section 2.3 and fuel oil valve opening 1 just as, the external diameter of described the 3rd measuring section 2.3 is less than the internal diameter of corresponding conical section 1.4, that is to say described the 3rd measuring section 2.3 and conical section 1.4 clearance fit when measuring, the clearance fit of present embodiment is generally about 0.02mm.
Also be combined with handle on the last plane of described first measuring section 2.1, make things convenient for putting into fuel oil valve opening 1 and taking out of measuring 2 from fuel oil valve opening 1.
Measuring method of the present utility model: the zero-bit that the distance on the plane, bottom of the last plane of first measuring section 2.1 of measuring 2 and the 3rd measuring section 2.3 is processed into the drawing tolerance.During measurement, earlier measuring 2 is put in the fuel oil valve opening 1, with first measuring section 2.1 of dial gauge measuring amount concrete 2 and the difference in height of cylinder cover upper planar surface, this difference in height is converted into the distance of the axis direction of measuring 2, again and then add the last plane of first measuring section 2.1 of measuring 2 and the 3rd measuring section 2.3 the plane, bottom distance just for the bottom center of the conical section 1.4 of fuel oil valve opening 1 between the center, upper end of seal section 1.1 apart from d.
