Specific embodiment

A kind of engine cylinder cover lubricating oil pump mounting surface position degree detection method of the present invention, in order to improve lubricating oil pump mounting surface Position degree detection efficiency, this detection method uses special detection device.Covered in qualified finished cylinder, lubricating oil pump mounting surface has one Fixed inclination angle, the axis of lubricating oil pump mounting hole is vertical with lubricating oil pump mounting surface.

As shown in Figures 1 to 6, the detection means that this detection method is used includes base plate 1 and the hole with lubricating oil pump mounting hole Footpath size identical test bar 5, base plate 1 is provided with detent mechanism for being positioned to cylinder cap to be detected 6 and positioned at detent mechanism one The detection plate 4 of side, it is identical that detection plate 4 includes that the inclined lubricating oil pump mounting surface for setting and being covered with qualified finished cylinder has The hang plate 41 at angle of inclination, hang plate 41 is provided with and allows test bar 5 to pass through and identical with the pore size of lubricating oil pump mounting hole Detection hole, detect hole axis it is perpendicular with hang plate 41, detect when, cylinder cap to be detected 6 is placed on detent mechanism, Detection plate 4 be located at cylinder cap to be detected 6 side and with the aligned in position of lubricating oil pump mounting surface 8, detection hole and machine oil in detection plate 4 Pump mounting hole is coaxial, and by the insertion detection hole downward-sloping first of test bar 5, as long as test bar 5 can pass through detection, hole is inserted Enter in lubricating oil pump mounting hole, illustrate that orifice position of the lubricating oil pump mounting hole on lubricating oil pump mounting surface 8 is accurate, so that just can be with Judge that the position degree of the lubricating oil pump mounting surface 8 on cylinder cap to be detected 6 meets the requirements, the position degree of lubricating oil pump mounting hole is equally also accorded with Close and require.

Specifically, test bar 5 is made of round bar, including the test section for detecting and the gripping for gripping Portion, shape and diameter and the lubricating oil pump between test section and grip part with an annular stop block, test section detects hole Identical, limited block is that the detection Kong Zhonghou in the insertion detection plate 4 of test bar 5 carries out spacing, the diameter of limited block to test bar 5 Aperture compared with detection hole is big.The simple structure of test bar 5 of this structure, installs hole shape and matches, it is possible to increase inspection with lubricating oil pump The accuracy of survey.

Detection plate 4 also include a vertical plate 42, hang plate 41 be located at vertical plate 42 top, hang plate 41 and vertically Plate 42 is formed in one.Vertical plate 42 is the top surface for being vertically mounted on base plate 1, is fixed by screw.Base plate 1 is rectangle, its chi Quite, detection plate 4 is located at a corner positions of base plate 1 for very little size and cylinder cap to be detected 6, with cylinder cap to be detected 6 on The aligned in position of lubricating oil pump mounting surface 8.The inclined upward that hang plate 41 is directed towards detent mechanism stretches out, and hang plate 41 is used as detection Benchmark, its inclination angle is equal with the inclination angle of the lubricating oil pump mounting surface that qualified finished cylinder is covered.

The detent mechanism of this detection means includes that 2 and and alignment pin are followed closely in the supporting being located on base plate 1.Supporting nail 2 is provided with four It is individual, four supporting nail 2 respectively correspond to cylinder cap to be detected 6 four corner positions, generally rectangular shaped distribution, cylinder cap to be detected 6 with Its bottom surface is placed on the supporting plane that four supporting nails 2 are formed.The top surface of each supporting nail 2 is plane, and flatness is very small, It is i.e. consistent with the positioning requirements that cylinder cap is processed, by supporting this design of nail 2, the stabilization support to cylinder cap to be detected 6 is formed, To improve accuracy of detection.

Alignment pin is provided with two, and one of them is straight pin 3, and another is rhombus pin 7, and two alignment pins are along base plate 1 Length direction is arranged side by side, and respectively close to a supporting nail 2.Using a straight pin 3, the positioning method of a rhombus pin 7, fixed During position, during two alignment pins are inserted into the corresponding holes of the bottom surface of cylinder cap 6 to be detected, and cylinder cap to be detected is suitably adjusted as needed 6 position can make cylinder cap to be detected 6 realize being accurately positioned, and be not only convenient for the easy to adjust of the position of cylinder cap to be detected 6, be also convenient for carrying The accuracy of the position degree of lubricating oil pump mounting surface 8 detection high.

Supporting nail 2 and alignment pin are arranged on base plate 1 by screw.

Detection method of the invention includes the steps:

(1)Base plate 1 is well placed, cylinder cap to be detected 6 is placed on the detent mechanism on base plate 1 and is positioned, and made to be detected The aligned in position of detection plate 4 on the lubricating oil pump mounting surface 8 and base plate 1 of cylinder cap 6;

(2)Using test bar 5, during test bar 5 to insert the detection hole in detection plate 4;

(3)Test bar 5 is promoted, test bar 5 is moved towards the lubricating oil pump mounting surface 8 on cylinder cap to be detected 6 through detection hole It is dynamic;

(4)Test bar 5 is continued to press on, if test bar 5 is inserted into lubricating oil pump mounting hole, is judged on cylinder cap to be detected 6 The position degree of lubricating oil pump mounting surface 8 meet the requirements;If test bar 5 can not be inserted into lubricating oil pump mounting hole, judge to be checked The position degree of the lubricating oil pump mounting surface 8 surveyed on cylinder cap 6 is undesirable.

Therefore above-mentioned detection means is used, the whole detection process of detection method is simple, easy to operate, improves machine oil The detection efficiency of the position degree of pump mounting surface 8, detection accuracy is good, detect the cylinder cap employee be even more without training by behaviour on duty Make.

The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented and do not receive aforesaid way Limitation, as long as employing the improvement of various unsubstantialities that method of the present invention design and technical scheme are carried out, or without changing Enter and design of the invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
