Abstract
The invention discloses a method for repairing a bolt hole of a cylinder cover, which is used for repairing the bolt hole when the bolt hole leaks. The method comprises the following steps of: expanding the bolt hole, to be repaired, of the cylinder cover, namely expanding the diameter of the bolt hole for 2.5 mm; precisely reaming the expanded bolt hole, wherein the diameter of the precisely reamed bolt hole is expanded for 3 mm on the basis of an original size; coating a repair adhesive on the inner wall of the precisely reamed bolt hole; cooling a prepared insert bush which is adapted to the precisely reamed bolt hole in liquid nitrogen; and pressing the cooled insert bush into the bolt hole in which the adhesive is coated, so that the insert bush expands at normal temperature to form interference fit with the bolt hole. In the repair method, only leaky bolt holes need to be repaired, so that the cylinder cover of which the bolt hole has leakage defects can be saved so as not to be scrapped totally, and the cost is low.
Description
Technical field
The present invention relates to a kind of method for repairing and mending of mechanical field, particularly a kind of cylinder head bolt hole method for repairing and mending.
Background technology
At present, after the processing of part engine cylinder cover seepage defect is arranged, incidence is about 1%, and wherein greatly a part is the bolt hole seepage that connects cylinder block.If the generation seepage is very big to the performance impact of engine, thus most of cylinder cover manufacturer pressure water leak test operation all after processing, to judge whether seepage.If generation seepage, cylinder cover need to scrap to a great extent, cause great waste.
Summary of the invention
The present invention is in order to overcome defective in the above-mentioned prior art, only needs to repair the bolt hole of seepage, and can save bolt hole has that the cylinder cover of seepage defect is unlikely all to be scrapped, and with low cost.
Cylinder head bolt of the present invention hole method for repairing and mending is used for when bolt hole generation seepage it is repaired to comprise the steps: to treat repairing the cylinder head bolt hole and carrying out reaming, and diameter of bolt hole is enlarged 2.5mm; Bolt hole after the reaming is finish reamed, and the diameter of bolt hole after finish reaming enlarges 3mm on the basis of its original size; Bolt hole inwall after finish reaming is smeared repair sheets; With previously prepared with finish ream after the suitable edge cover of bolt hole put into liquid nitrogen and cool off; Cooled edge cover is pressed into bolt hole behind the gluing, and normal temperature edge cover down expands and bolt hole forms interference fit.
Wherein, the diameter of waiting to repair the cylinder head bolt hole is 15mm, and the diameter of bolt hole after the reaming is 17.5mm, and the diameter of bolt hole after finish reaming is 18mm; The margin of tolerance of the diameter of bolt hole after finish reaming for-0.045mm to-0.02mm; The external diameter margin of tolerance of edge cover be+0.025 to+0.048mm, and it is 15mm that edge overlaps internal diameter.
Wherein, liquid nitrogen temperature is-190 ℃ to-197 ℃.
Wherein, the cooled with liquid nitrogen time is 10 to 30 minutes; Be preferably 20 minutes.
Wherein, repair sheets are Lip river mixture and alloy, pottery, diamond dust, and are formulated.
Wherein, the edge cover adopts copper material.
Compared with prior art, bolt hole method for repairing and mending of the present invention is simple to operate; By reaming, finish ream bolt hole and make it reach diameter dimension in the tolerance allowed band; By cooled with liquid nitrogen and the suitable edge cover of bolt hole, make its after recovering normal temperature with the bolt hole interference fit, mending-leakage is effective, need not bigger input.

The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subjected to the restriction of the specific embodiment.
To shown in Figure 5, cylinder head bolt of the present invention hole method for repairing and mending is specific as follows as Fig. 1: at first reaming is carried out in the cylinder head bolt hole that seepage takes place earlier, promptly elder generation expands into Φ 17.5mm to the bolt hole of Φ 15mm; Ream accurately again, the hole that is about to Φ 17.5mm finish ream into
(margin of tolerance be-0.045 to-0.02mm), the original pacch bolt hole for the treatment of is enlarged 3mm; Coat repair sheets then on the bolt hole that has enlarged, repair sheets are Lip river mixture and alloy, pottery, diamond dust, and are formulated; To be pressed in the bolt hole through the edge cover of cooled with liquid nitrogen at last, the edge cover adopts copper material, and liquid nitrogen temperature is-190 ℃ to-197 ℃, is preferably-195 ℃.The time of cooling off in liquid nitrogen container can be 10 to 30 minutes, and preferred 20 minutes, this edge cover external diameter was
(margin of tolerance be+0.025 to+0.048mm), interior diameter remains Φ 15m (promptly the diameter of bolt hole with needs is identical), the edge that is pressed into is enclosed within and expands under the normal temperature and bolt hole forms interference fit, repair sheets play further sealing mending-leakage simultaneously.So far finished the whole process that inlays.
Bolt hole method for repairing and mending of the present invention is applied to the reparation in cylinder head bolt hole, and mending-leakage is effective, and is simple to operate, do not need higher input to finish, and the whole of cylinder cover that avoided the localized seepage because of bolt hole to cause scrap.
More than disclosed only be a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
