Abstract
The invention relates to the field of mechanical parts repair processes, in particular to a repairing method for leakage of an installation screw hole on the installation surface of an integration box. The repairing method comprises the following steps of: a. reaming the installation screw hole having leakage problem to a screw thread hole; b. turning a matched red copper gasket; c. cleaning the screw thread hole, and placing the red copper gasket to the bottom of the screw hole; d. turning a matched screw sleeve; e. uniformly coating screw thread locking agent on the outside of the screw sleeve and screwing the screw sleeve to the screw thread hole; f. milling the outer end of the screw sleeve to be in parallel with the installation surface of the integration box after the screw thread locking agent is cured; and g. drilling a new installation screw hole on the screw sleeve. The repairing method is simple, practical and convenient, has good effect for the leakage problem of the installation screw hole caused by shrinkage cavity and porousness, avoids scrapping of parts, prolongs the service life of the parts, and greatly saves production cost.
Description
Technical field
The present invention relates to machine components repair technology field, the restorative procedure that screw leaks is installed on especially a kind of integrated case installed surface.
Background technology
Because integrated casing is whole iron casting, the die cavity complexity, casting manufacturability is poor, after the boring, there are shrinkage cavity and loose problem in the installation screw on its installed surface, cause installing screw and oil duct or water channel and connect and the generation leakage, part can't be used and scrap, cause great economic loss.
Summary of the invention
The installation screw easily produces leakage problem on the existing integrated case installed surface in order to overcome, and causes the deficiency of very big economic loss, the invention provides the restorative procedure that screw leaks is installed on a kind of integrated case installed surface.
The technical solution adopted for the present invention to solve the technical problems is: the restorative procedure that screw leaks is installed on a kind of integrated case installed surface, is may further comprise the steps:
A. will exist the installation screw reaming of leakage problem to be processed into M24 * 1.5, the screwed hole of bottom outlet ￠ 22.5mm, screw thread adopts fine thread, and the degree of depth surpasses more than the 5mm of leakage point position, and the bottom ream is flat;
B. car system thickness is 1-2mm, the red copper pad of ￠ 22.5mm, and the sharp edge abate, and with oxy-acetylene that its burning is red, make its annealing deliquescing;
C. will clean up in the screwed hole, red copper pad trimming is put to the screwed hole bottom after smooth;
D. the swivel nut of car system M24 * 1.5, length surpasses screwed hole degree of depth 10mm;
E. after the swivel nut appearance is evenly coated the screw-threaded coupling agent, screw in screwed hole, and tighten, until the red copper pad is thoroughly compressed;
F. after treating that the screw-threaded coupling agent is solidified, the outer end mill of swivel nut is become flat together with integrated case installed surface;
G. on swivel nut, get out a new screw of installing.
The invention has the beneficial effects as follows that this restorative procedure is simple, practical, convenient, respond well to solving because of the leakage problem of shrinkage cavity and the loose installation screw that causes, avoided scrapping of part, prolonged the service life of part, saved production cost greatly.
