The using method that cylinder head is bored guide pillar hole aligning tool is: 1. cylinder head is arranged on and on fixture, makes the axis of valve guide bushing installing hole parallel with boring spindle axis, the direction that the residing plane of axis of upper and lower two valve guide bushing installing holes moves up and down with boring spindle is parallel; 2. circle alignment pin is contained in the following valve guide bushing installing hole of cylinder head, rhombus pin is contained in the valve guide bushing installing hole of top of cylinder head, dial gauge is contained on boring spindle, and dial indicator measuring head is pressed on centering post; Rotating spindle, makes axis and the boring spindle axis coaxle of centering post, records the position a of boring spindle axis above-below direction; 3. circle alignment pin is contained in the valve guide bushing installing hole of top of cylinder head, rhombus pin is contained in the following valve guide bushing installing hole of cylinder head, dial gauge is contained on boring spindle, dial indicator measuring head is pressed on centering post, boring spindle moves up and down relevant position, rotating spindle, makes axis and the boring spindle axis coaxle of centering post, records the position b of boring spindle axis above-below direction; 4. the position of boring spindle axis is moved to a of boring spindle axis above-below direction and the position in the middle of b; 5. start to process guide pillar hole, with drill bit slightly hole → with boring cutter rough bore → with cornish bit reaming → finish ream hole with reamer.6. use the same method and process the guide pillar hole of cylinder head another side.
The advantage that this cylinder head is bored guide pillar hole aligning tool is: reasonable positioning, precision is high.Easy to operate in the time of processing, position and the dimensional accuracy of boring are high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing is the installation diagram that cylinder head is bored guide pillar hole aligning tool.Fig. 1 is front view, Fig. 2 be Fig. 1 along the cutaway view of A-A, Fig. 3 is that Fig. 2 is along the cutaway view of B-B.
1. cylinder head in figure, 2. rhombus pin, 3. plate, 4. centering post, 5. justifies alignment pin.
The specific embodiment
Accompanying drawing is the installation diagram that 16V240ZJ cylinder cover for diesel engine (1) bores guide pillar hole aligning tool.
With reference to accompanying drawing, the diameter of the conduit installing hole of 16V240ZJ cylinder cover for diesel engine (1) is that 28 millimeters of guide pillar bore dias are 22 millimeters, and 104 ± 0.2 millimeters of the distances of homonymy two guide holes require guide pillar hole in the centre of homonymy two guide holes.Together with the valve seat insert hole that conduit installing hole must be coaxial with it, from the combustion front of cylinder head (1), process, guide pillar hole will be from the another side processing of cylinder head (1).According to the operation principle of cylinder head (1), the guide pillar hole of homonymy is associated with conduit installing hole.The position in guide pillar hole is that the positioning datum of aligning tool is exactly two conduit installing holes of cylinder head (1), can adopt the positioning form of conventional one side double-pin by the determining positions of cylinder head (1) conduit installing hole.Cylinder head (1) is bored guide pillar hole aligning tool, comprises rhombus pin (2), plate (3), centering post (4) and circle alignment pin (5).Rhombus pin (2) is contained in the cylinder of its small end in the hole of top of plate (3), and the central plane of two column parts that coordinate with associated orifices of rhombus pin (2) is vertical with the plane at circle alignment pin (5) axis place with rhombus pin (2).Centering post (4) is contained in the cylinder of its small end in the hole of centre of plate (3), and circle alignment pin (5) is contained in the following hole of plate (3) with the cylinder of its small end.The axis of rhombus pin (2), centering post (4) and circle alignment pin (5) is in same plane and be parallel to each other, and rhombus pin (2) is contained in respectively in the valve guide bushing installing hole of cylinder head (1) homonymy with circle location (5).According to pattern requirement, rhombus pin (2) axis equates with the distance of circle alignment pin (5) axis to centering post (4) axis to the distance of centering post (4) axis.In order to extend the service life of aligning tool, rhombus pin (2), centering post (4) and circle alignment pin (5) heat 58～62HRC of place.
