Abstract
The invention provides a control method of the thickness of the outer wall of a water channel of an air cylinder cover. The method includes the steps that the air cylinder cover is clamped on a four-jaw chuck and aligned with larger inner holes of a combustion chamber on a blank, steel columns remaining in small inner holes of the combustion chamber are drilled through a small-diameter drill bit, and the holes are milled through a vertical mill and turned through a turning tool; a correction block is made of a material the same as that of the air cylinder cover, wherein the thickness sigma of the correction block is the nominal size of the outer wall of the water channel; the inner end face of the large inner holes of the combustion chamber are roughly turned, after the diameter portions of bridges of the four air valve holes are turned through the turning tool, the thickness sizes of the bridges of the four air valve holes are measured through ultrasonic waves, the thickness sizes of the four bridges are basically identical by adjusting the axial position of the air cylinder cover on the four-jaw chuck, and the inner end face of the large inner holes and the large inner holes of the combustion chamber are precisely turned according to measured data; the thicknesses of the four bridges can meet the drawing requirements alpha; and the outer end face of the large inner holes is turned according to the size from the inner end face of the large inner holes to the outer end face of the large inner holes. By the adoption of the control method, the thickness of the outer wall of the water channel is directly measured so that the air cylinder cover can be machined rapidly and accurately.
Description
Art
The present invention relates to mechanical processing technique, especially the control method of cylinder head waterway outer wall thickness.
Background technology
Current high-power diesel engine is all generally that a cylinder joins a cylinder head.Cylinder head will work under larger load and under the situation of higher temperature, and condition of work is severe.Cylinder head is generally with alloy or vermicular iron manufacture.In order to the cooling cylinder cover of the thermojunction and cylinder head work that reduce molten iron cast is also designed with complicated cooling system.In order to the wall thickness reducing thermal stress key position when cylinder head works has strict demand.Position custom between two valve valve openings claims gap bridge place, and the outer wall of gap bridge place waterway, must reach the tolerance of configurations.Waterway outer wall can not use general gage measuring, complete in casting experience control in the past, manufacture-illegal often not science.
Summary of the invention
The object of the invention is the defect overcoming prior art, a kind of control method of cylinder head waterway outer wall thickness is provided, directly measure the thickness of waterway outer wall, the processing tasks of this operation of cylinder cover can be completed fast and accurately.
The object of the invention is to realize as follows: the controlling organization of cylinder head waterway outer wall thickness comprises chuck jaw, proof-reading block, sonigauge, instructed by the actual (real) thickness of measurement waterway outer wall to cut: cylinder head clamping on the chuck of lathe, by the large endoporus centering in the combustion chamber on cast blank, the steel column in the little endoporus of combustion chamber is retained in by the bit drills of minor diameter, use slotting cutter reaming again, with lathe tool car hole; The material of proof-reading block is identical with cylinder cover, and its thickness б is the nominal dimension of waterway outer wall; The inner face of the large endoporus in rough turn combustion chamber, after the diameter of four valve valve openings gap bridges crossed by lathe tool car, the gauge at four valve valve opening gap bridge places is measured one by one with sonigauge, by the axial location of adjustment cylinder head on the chuck jaw of chuck, make the size of four gap bridge place thickness basically identical, according to inner face and the large endoporus of the large endoporus in measurement data finish turning combustion chamber; Four gap bridge place thickness are made to reach pattern requirement α; According to the inner face of the large endoporus size to the outer face of large endoporus, the outer face of the large endoporus of car reaches pattern requirement.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing is the structure chart of 16V240 cylinder cover for diesel engine waterway.

1. cylinder head in figure; 2. chuck jaw; 3. the inner face of large endoporus; 4. the outer face of large endoporus; 5. waterway; 6. proof-reading block; α. the thickness of waterway outer wall; β. proof-reading block gauge.
Detailed description of the invention
With reference to accompanying drawing, the controlling organization of cylinder head waterway outer wall thickness comprises chuck jaw (2), proof-reading block (6) and sonigauge, be instruct lathe tool to cut by the actual (real) thickness of measurement waterway (5) outer wall, the control method of cylinder head waterway (5) outer wall thickness is; Cylinder head (1) clamping on the chuck of lathe, by cast blank profile centering, make the axis of the large endoporus in car combustion chamber on cast blank coaxial with lathe spindle rotation, because the little endoporus of combustion chamber is the pore that casting is formed, casting technique is had to need the steel column stayed, by the bit drills of minor diameter, with slotting cutter reaming, steel column is removed, with lathe tool, little endoporus car is become; The material of proof-reading block (6) is identical with the material of cylinder cover (1), and its thickness б is the nominal dimension of waterway (5) outer wall, to ensure that measurement data is accurate; The inner face (3) of the large endoporus in rough turn combustion chamber, the rough turn mistake of lathe tool four valve valve opening gap bridge places diameter after, the gauge at four valve valve opening gap bridge places is measured one by one with sonigauge, if the gauge measuring four valve valve opening gap bridge places is inconsistent, can, by adjustment cylinder head (1) axial location on chuck jaw (2), make the gauge at four gap bridge places substantially identical; According to inner face (3) and the large endoporus of the large endoporus in measurement data finish turning combustion chamber; The thickness at valve valve opening gap bridge place is made to be α; According to the inner face (3) of the large endoporus size to the outer face (4) of large endoporus, the outer face (4) of the large endoporus of car reaches pattern requirement.
Claims (1)
1. the control method of a cylinder head waterway outer wall thickness, the controlling organization of cylinder head waterway outer wall thickness comprises chuck jaw, proof-reading block, sonigauge, instructed by the actual (real) thickness of measurement waterway outer wall to cut, it is characterized in that: cylinder head clamping on the chuck of lathe, by the large endoporus centering in the combustion chamber on cast blank, be retained in the steel column in the little endoporus of combustion chamber by the bit drills of minor diameter, then use slotting cutter reaming, with lathe tool car hole; The material of proof-reading block is identical with cylinder cover, and its thickness 6 is nominal dimensions of waterway outer wall; The inner face of the large endoporus in rough turn combustion chamber, after the diameter of four valve valve openings gap bridges crossed by lathe tool car, the gauge at four valve valve opening gap bridge places is measured one by one with sonigauge, by adjustment cylinder head four, axial location on the chuck jaw of dog chuck, make the size of four gap bridge place thickness substantially identical, according to inner face and the large endoporus of the large endoporus in measurement data finish turning combustion chamber; Four gap bridge place thickness are made to reach pattern requirement α; According to the inner face of the large endoporus size to the outer face of large endoporus, the outer face of the large endoporus of car reaches pattern requirement.
