Cubing gauge head 7 is the flat body of " fourth " word shape, and flat body thickness is 10-25mm, and its upper surface is provided with screw thread and pin hole, and its head front side is special surface 4.
Straight pin 3 is sold with the identical weak point that is of plunger external diameter of chamfered edge pin 5, and both afterbodys are identical.Straight pin 3 is identical with base plate 1 front-seat two pin-and-hole diameter dimensions with chamfered edge pin 5 tail diameter sizes.
Straight pin 3 and chamfered edge pin 5 are separately positioned in the front-seat pin-and-hole of base plate 1 lower plane.Four cubing gauge heads 7 equidistantly are fixed on respectively the first half of the lower plane of base plate 1 by fillister head screw 2 and pin 6, the internal arm distance of every adjacent cubing gauge head 7 is 80-110mm.Straight pin 3 center lines are 10-15mm with the distance that is distributed in the from left to right first row cubing gauge head 7 mid-depth lines on the base plate 1.
Two pin-and-holes of base plate 1 consistent apart from size with cylinder of diesel engine bottom surface two technique pin-and-holes apart from size.
Straight pin 3 is identical with cylinder block bottom surface two technique pin-and-hole internal diameter sizes with the plunger outside dimension of chamfered edge pin 5.
The flat body thickness size of cubing gauge head 7 is consistent with diesel engine cylinder main oil duct hole lateral wall gauge.
The internal arm carpenters square of every adjacent cubing gauge head 7 is very little very little consistent with each adjacent mail gallery holes internal arm carpenters square of cylinder of diesel engine.
The upper surface of cubing gauge head 7 is consistent with respect to the radius-of-curvature that is contained in the connecting rod in the body with respect to plane on the radius-of-curvature of special surface 4 and the diesel-engine body.
Technique effect of the present invention is embodied in following several aspect:
1. can find earlier the interference of diesel engine cylinder main oil duct and connecting rod, reduce unnecessary assembling and reprocessed cost, improve work efficiency;
2. testing process is simple and convenient, can detect the particular location of interference, for the repair of cylinder of diesel engine provides the analysis foundation.

Embodiment
A kind of cubing that detects diesel engine cylinder main oil duct and interference of link comprises base plate 1, fillister head screw 2, straight pin 3, chamfered edge pin 5, pin 6 and cubing gauge head 7.
Base plate 1 is rectangular bar of steel plate, and latter half of at steel plateelement is the hollow out rectangle frame, first half equidistantly distribute four row screw threads and pin group hole.Be provided with two pin-and-holes in that steel plateelement is the most front-seat, the distance of two pin-and-holes is 320mm.Two pin-and-holes of base plate 1 consistent apart from size with cylinder of diesel engine bottom surface two technique pin-and-holes apart from size.
The benefit of the hollow out rectangle frame on the base plate 1 has 3 points: 1, be convenient to hold and put; 2, be convenient to observe the inner case of cubing gauge head and cylinder block main oil gallery; 3, rationally go heavily to carry light.
Cubing gauge head 7 is the flat body of " fourth " word shape, and flat body thickness is 20mm, and its upper surface is provided with screw thread and pin hole, and its head front side is special surface 4.
Straight pin 3 is sold with the identical weak point that is of plunger external diameter of chamfered edge pin 5, and both afterbodys are identical.Straight pin 3 is identical with base plate 1 front-seat two pin-and-hole diameter dimensions with chamfered edge pin 5 tail diameter sizes.
Straight pin 3 and chamfered edge pin 5 are separately positioned in the front-seat pin-and-hole of base plate 1 lower plane.Four cubing gauge heads 7 equidistantly are fixed on respectively the first half of the lower plane of base plate 1 by fillister head screw 2 and pin 6.Every cubing gauge head 7 is by two pins, 6 location with base plate 1, then be fixed on the base plate 1 with fillister head screw 2, has guaranteed that every cubing gauge head 7 is with respect to absolute accurate in the position of cylinder block.The internal arm distance of every adjacent cubing gauge head 7 is 100mm.Straight pin 3 center lines are 10mm with the distance that is distributed in the from left to right first row cubing gauge head 7 mid-depth lines on the base plate 1.
Straight pin 3 is identical with cylinder block bottom surface two technique pin-and-hole internal diameter sizes with the plunger outside dimension of chamfered edge pin 5, cooperates with cylinder block oil sump face technique pin-and-hole by straight pin 3 and chamfered edge pin 5, and cubing is implemented the location exactly.
The flat body thickness size of cubing gauge head 7 is consistent with diesel engine cylinder main oil duct hole lateral wall gauge.
The internal arm carpenters square of every adjacent cubing gauge head 7 is very little very little consistent with each adjacent mail gallery holes internal arm carpenters square of cylinder of diesel engine.
The upper surface of cubing gauge head 7 is consistent with respect to the radius-of-curvature that is contained in the connecting rod in the body with respect to plane on the radius-of-curvature of special surface 4 and the diesel-engine body.The processing mode of cubing gauge head 7 is: utilize first special-purpose software accurately to simulate the envelope of connecting rod, then the top with cubing gauge head 7 processes in strict accordance with the envelope that simulates, be processed into special surface 4, by the control of cubing position dimension, the consistance of the track that forms when guaranteeing special surface 4 with the connecting rod actual rotation.
Below in conjunction with accompanying drawing, by embodiment the present invention is further described.
Embodiment:
During work, referring to Fig. 3 and Fig. 4, straight pin 3 on the cubing and chamfered edge pin 5 are inserted in two the technique pin-and-holes in cylinder block bottom surface, whether then observe the lower plane 8 of base plate 1 fits with cylinder block oil sump face 9, if fit, illustrate that then special surface 4 and main oil gallery lateral wall do not interfere, namely connecting rod and main oil gallery are not interfered in the real process; If gapped between the two, illustrate that then both interfere, cubing under this time shift, every grade of mail gallery holes place coats chalk in cylinder block, again detects, and takes off cubing again, observes the special surface 4 on cubing gauge head 7 tops, has the chalk dust place then to illustrate herein and interferes.
The present invention is very low to the processing request of cylinder block, as long as process the upper plane of oil sump face and two fabrication holes on upper plane can detect, if detect interference, can avoid the unnecessary processing in back.The present invention has controlled the generation that occurs cylinder block and interference of link situation in the assembling process effectively by nearly 1 year use.
