Description
Art
The present invention relates to mechanical processing technique equipment, the especially assembly method of cylinder head interstitial hole part.
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 generally manufactures with alloy cast iron.Because its complex structure, multiple casting technique hole to be designed when cylinder head cast blank, with after relevant Assembly of the parts, cold water cavity be sealed after waiting for cylinder head machining.The assembly quality of the part of cylinder head interstitial hole directly affects the sealing property of cylinder head.
Summary of the invention
The object of the invention is the defect overcoming prior art, a kind of assembly method of cylinder head interstitial hole part is provided, the cylinder cover hydraulic after assembling can be made to test completely qualified.
The object of the invention is to realize as follows: the assembly method of cylinder head interstitial hole part, relates to cylinder head, spline screw plug spanner, spline screw plug, sleeve handle, sealing ring, sleeve, mandrel stock, copper packing and mandrel.Installation step is: 1. the cylinder head cleaned up is placed on to install and flat board makes hole that cylinder head intermediate sizes is large on top; 2. mandrel stock is contained on mandrel, utilizes mandrel stock to be contained in by mandrel in the following hole of cylinder head; 3. copper packing is contained in the following of the interstitial hole of cylinder head by mandrel stock and mandrel; 4. be contained in the groove of sleeve by sealing ring, sleeve being contained on sleeve, under the guiding of mandrel, grip wound packages is in copper packing top; 5. utilize spline screw plug spanner that spline screw plug is contained in sleeve top clamp sleeve; 6. unload spline screw plug spanner, sleeve handle and mandrel stock successively; 7. spline screw plug is tightened again by standard-required with special spline torque spanner; 8. mandrel stock is contained on mandrel and takes off mandrel; 9. cylinder head turn over reamer hinge repair the following hole of cylinder head.
The advantage of the assembly method of this cylinder head interstitial hole part is: reasonable positioning, easy to operate, precision is high.Particularly thoroughly solve the difficult problem that copper packing place leaks, the assembly quality of cylinder head interstitial hole part is reached absolutely.

Detailed description of the invention
With reference to accompanying drawing, the assembly method of cylinder head interstitial hole part, relates to cylinder head (1), spline screw plug spanner (2), spline screw plug (3), sleeve (4), sealing ring (5), sleeve (6), mandrel stock (7), copper packing (8) and mandrel (9).The part assembled in cylinder head (1) interstitial hole is: copper packing (8) is contained in bottom, and top is sleeve (6), and spline screw plug (3), sleeve (6), compresses.The sealing ring (5) be contained on sleeve (6) seals the water cavity of cylinder head (1) top, and copper packing (8) seals the following water cavity of cylinder head (1).The following hole of the following hole of cylinder head (1) interstitial hole and copper packing (8) endoporus, sleeve (6) is coaxial.Copper packing (8) is bonded at the upper installation of sleeve (6) with the location, hole that sleeve (6) is following in the past, sticky insecure, often comes off, unreliable.The more important thing is when copper packing (8) compressive deformation, by the constraint in the following hole of jacket casing (6), be out of shape insufficient.Cause water pressure test seepage.Now copper packing (8) cylindrical is diminished and just can address this problem.But difficulty is brought to assembling.The assembly method of cylinder head interstitial hole part has been invented for this problem.1) cylinder head cleaned up (1) is placed on to install flat board makes hole that cylinder head (1) intermediate sizes is large on top; 2) mandrel stock (7) is contained on mandrel (9), utilizes mandrel stock (7) to be contained in the following hole of cylinder head (1) by mandrel (9).For assembling copper packing (8) is prepared; 3) copper packing (8) is contained in the following of the interstitial hole of cylinder head (1) by mandrel stock (7) and mandrel (9).The hole that the endoporus of copper packing (8) so just can be made following with cylinder head (1) interstitial hole is coaxial; 4) sealing ring (5) is contained in the groove of sleeve (6), sleeve is contained on sleeve (6) (4), under the guiding of mandrel (9), sleeve (6) is contained in copper packing (8) top.Also following with cylinder head (1) interstitial hole hole, the following hole of such sleeve (6) is coaxial.If need in assembling process, sleeve (6) is taken off, also use sleeve (4).Firmly upwards can pull out inserting a corresponding cylinder in the hole of (4) top at sleeve if desired; 5) utilize spline screw plug spanner (2) that spline screw plug (3) is contained in sleeve (6) top clamp sleeve (6); 6) spline screw plug spanner (2), sleeve is unloaded successively (4) and mandrel stock (7); 7) because the length of spline screw plug spanner (2) is short, the power of tightening spline screw plug (3) with spline screw plug spanner (2) may not reach requirement.So again with special spline torque spanner, spline screw plug (3) is tightened again by standard-required.Defeat tight copper packing (8) with larger, the part metals after the distortion of copper packing (8) cylindrical can not encounter the outer wall of sleeve (6) corresponding aperture.Therefore seepage can not be caused; 8) mandrel stock (7) is contained on mandrel (9) takes off mandrel (9).A corresponding cylinder can be inserted if desired firmly upwards pull out in the hole of mandrel stock (7) top; 9) gap is had because of the hole that mandrel (9) and cylinder head (1) interstitial hole are following, tight copper packing (8) is defeated with larger, part metals after copper packing (8) Internal Hole Deformation can give prominence to the inwall in the following hole of cylinder head (1) interstitial hole, just hole following for cylinder head (1) interstitial hole to be fixed with corresponding reamer cylinder head (1) is turned over.
