Embodiment
A kind of cubing that detects cylinder of diesel engine main oil gallery and connecting rod interference 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 a 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 at the front row of steel plateelement, the distance of two pin-and-holes is 320mm.Two pin-and-holes of base plate 1 consistent apart from size apart from size and cylinder of diesel engine bottom surface two technology pin-and-holes.
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 a special surface 4.
Straight pin 3 is sold with the identical weak point that is of a pin 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 is separately positioned in the front-seat pin-and-hole of base plate 1 lower plane with chamfered edge pin 5.Four cubing gauge heads 7 respectively through fillister head screw 2 and pin 6 equidistantly be fixed on the lower plane of base plate 1 first half.Every cubing gauge head 7 is through two pins, 6 location with base plate 1, be fixed on the base plate 1 with fillister head screw 2 then, 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.To play the distance of the first row cubing gauge head, 7 mid-depth lines be 10mm to straight pin 3 center lines with being distributed in a left side on the base plate 1.
Straight pin 3 is identical with cylinder block bottom surface two technology pin-and-hole internal diameter sizes with a pin outside dimension of chamfered edge pin 5, cooperates with cylinder block oil sump face technology pin-and-hole through straight pin 3 and chamfered edge pin 5, and cubing is implemented the location exactly.
The flat body thickness size and the cylinder of diesel engine mail gallery holes lateral wall gauge of cubing gauge head 7 are consistent.
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 special-purpose software accurately to simulate the envelope of connecting rod earlier; Top with cubing gauge head 7 processes in strict accordance with the envelope that simulates then; Be processed into special surface 4; Through 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, the utility model is done explanation further through embodiment.
Embodiment:
During work; Referring to Fig. 3 and Fig. 4; Straight pin on the cubing 3 and chamfered edge pin 5 are inserted in two the technology pin-and-holes in cylinder block bottom surface, observe the lower plane 8 of base plate 1 then and whether fit, if fit with cylinder block oil sump face 9; Explain that then special surface 4 and main oil gallery lateral wall do not interfere, just connecting rod and main oil gallery are not interfered in the real process; If gapped between the two, explain that then both interfere, cubing under this time shift, every grade of mail gallery holes place coats chalk in cylinder block, detects again, takes off cubing again, observes the special surface 4 on cubing gauge head 7 tops, has the chalk dust place then to explain here and interferes.
The utility model is very low to the processing request of cylinder block, as long as two fabrication holes that process the last plane of oil sump face and go up the plane can detect, if detect interference, can avoid the unnecessary processing in back.The utility model has been controlled the generation that occurs cylinder block and connecting rod interference situation in the assembling process effectively through nearly 1 year use.
