Abstract
The present invention relates to mechanical repair technology, and is especially fast internal thread repairing process. The fast internal thread repairing process includes the following steps: 1. reaming the thread hole with worn thread; 2. machining internal thread sleeve with internal thread fitting the available screw bolt and outer diameter fitting the reamed hole; and 3. fixing the internal thread sleeve into reamed hole in the workpiece firmly. The said repair process can repair worn internal thread quickly and avoid discard of workpiece caused by worn internal thread.
Description
Technical field
The present invention relates to flight-line maintenance method and technology field, especially a kind of fast repairing method of internal screw.
Background technology
At mechanical field, the connection that many mechanical structured members are arranged is with being threaded, and the spinning in and out of the bolt of member in internal thread hole easily produce wearing and tearing each other in utilization, causes connecting loosening or loses efficacy.Sometimes very difficult or expense is very high, can only consider to start with from repairing the internal thread hole aspect this moment to the reparation of bolt, can not consider the part of replacing own to some as the internal thread hole on fuselage, the casing, can only manage the double thread hole repairs, when repairing, adopt methods such as plug-hole redrilling, dystopy boring, but the diameter dimension that this redrilling requirement can increase bolt simultaneously is just feasible, and dystopy boring is had relatively high expectations to structural flexibility, workpiece can only be scrapped when above-mentioned all methods can't be implemented.Only repairing screwed hole so require to have a kind of method to satisfy, and the reparation in double thread hole is in situ, also requirement can not change the restorative procedure of original thread bore dia.
Summary of the invention
The objective of the invention is in order to overcome the double thread hole and to repair under the situation that can't adopt methods such as plug-hole redrilling, dystopy boring, be difficult to implement this deficiency of the reparation in double thread hole.
The technical solution adopted for the present invention to solve the technical problems is: a kind of fast repairing method of internal screw has following processing step, 1), reaming is carried out in the original thread hole of wearing and tearing on the workpiece; 2), the preparation inner screw sheath, the internal thread of inner screw sheath and former bolt are adaptive, the external diameter of inner screw sheath matches with counter bore diameter on the workpiece; 3), inner screw sheath is placed in institute's reaming and with workpiece be connected and fixed with prevent inner screw sheath relative with workpiece rotation or come off.
It is at the place's of matching oral area at least one minor thread hole and at least one Screw of installation or the oral area employing at the place of matching to be set axially to be welded to connect fixing that described inner screw sheath places institute's reaming method interior and that workpiece is connected and fixed.
The outer wall that it is inner screw sheath that described inner screw sheath places institute's reaming method interior and that workpiece is connected and fixed adopts with the hole on the workpiece and is threaded, and at least one minor thread hole and at least one Screw of installation axially is set or is welded to connect fixing in the employing of screw thread oral area at the screw thread oral area.
The invention has the beneficial effects as follows: 1, improved the reparation speed after mechanical structured member connects the internal thread wearing and tearing of usefulness; 2, alleviated repair amount behind the internal thread abrasion; 3, reduced and to repair the workpiece that causes because of internal thread wearing and tearing and scrap.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of implementation method schematic diagram of the present invention.
Fig. 2 is an another kind of implementation method schematic diagram of the present invention.
The specific embodiment
As the fast repairing method of internal screw of accompanying drawing 1, earlier reaming is carried out in the original thread hole of wearing and tearing on the workpiece 1; Prepare inner screw sheath 2 then, the internal thread of inner screw sheath 2 and former bolt are adaptive, and the external diameter of inner screw sheath matches with counter bore diameter on the workpiece; Again inner screw sheath is placed in institute's reaming, the place's of matching oral area adopt be welded to connect fixing, to prevent that inner screw sheath is relatively and the rotation of workpiece or come off.Can carry out chamfering to the interior oral area of workpiece 1 and/or the outer port part of inner screw sheath 2 before the welding, be beneficial to welding, polish processing after the welding.
As the fast repairing method of internal screw of accompanying drawing 2, earlier the reaming tapping is carried out in the original thread hole of wearing and tearing on the workpiece 1; Prepare inner screw sheath 2 then, the internal thread of inner screw sheath 2 and former bolt are adaptive, and the external diameter machining screw of inner screw sheath matches with reaming tapping on the workpiece; Cooperate the back minor thread hole axially to be set and be screwed into a Screw again, to prevent that inner screw sheath 2 relatively and the rotation of workpiece 1 or come off at the screw thread oral area.
Claims (3)
1, a kind of fast repairing method of internal screw is characterized in that, has following processing step, 1) workpiece (1) is upward carried out reaming in the original thread hole of wearing and tearing; 2) preparation inner screw sheath (2), the internal thread and the former bolt of inner screw sheath (2) are adaptive, and the external diameter of inner screw sheath (2) matches with counter bore diameter on the workpiece (1); 3) inner screw sheath (2) is placed in institute's reaming and be connected and fixed with the rotation that prevents relative and the workpiece (1) of inner screw sheath (2) with workpiece (1) or come off.
2, fast repairing method of internal screw according to claim 1 is characterized in that: it is at the place's of matching oral area at least one minor thread hole and at least one Screw of installation or the oral area employing at the place of matching to be set axially to be welded to connect fixing that described inner screw sheath (2) places institute's reaming method interior and that workpiece (1) is connected and fixed.
3, fast repairing method of internal screw according to claim 1, it is characterized in that: the outer wall that it is inner screw sheath (2) that described inner screw sheath (2) places institute's reaming method interior and that workpiece (1) is connected and fixed adopts with the hole on the workpiece (1) and is threaded, and at least one minor thread hole and at least one Screw of installation axially is set or is welded to connect fixing in the employing of screw thread oral area at the screw thread oral area.
