Description
Technical field
The present invention relates to a kind of can precisely dismantle to belling shoulder piece cover instrument and dismounting to belling shoulder piece cover method.
Background technology
What is called refers to along matrix hole both sides the bushing combination formed after pressure one group of shouldered lining belling shoulder piece cover.In lining use procedure, due to liner wear or specification change, need dismounting and change lining.The method of tradition dismounting lining is, first on the lining inner hole wall of side, asymmetric buff goes out two grooves and relends and help hammer to exert a force, and exits along the lining of groove by opposite side.Lining exit requirement in process must not injure matrix bottom outlet surface, and dismantle lining by this kind of mode, because impulsive force is large and force direction is unstable, very easily cause matrix bottom outlet surface damage, whole matrix part rejection can be caused time serious, bushing dismounting quality is very unstable, brings greater risk to more resleeve.If constructed aboard, due to the impact force action of hammer, the part for poor rigidity likely produces distortion, thus affects aircraft product quality.
Summary of the invention
In order to overcome the above problems, the object of this invention is to provide one can precisely dismantle, and can not cause damage to matrix bottom outlet, ensures the instrument that the dismounting of bushing dismounting quality is overlapped belling shoulder piece.
Another object of the present invention be to provide a kind of utilize above-mentioned instrument precisely dismantle to belling shoulder piece cover method.
The technical solution used in the present invention is:
Dismantle the instrument to belling shoulder piece cover, be made up of block, bolt, nut I, nut II, jacking block I and jacking block II; The end, side of jacking block I is provided with the notch I coordinated with nut I, and the lateral surface of jacking block I is with two symmetrical arc boss; The end, side of jacking block II is provided with the notch II coordinated with nut I; Bolt one end is connected with nut II through after block; The other end of bolt is connected with the nut I be combined together by notch I and jacking block I, or is connected with the nut I be combined together by notch II and jacking block II.
Above-mentioned a kind of dismounting is to the instrument of belling shoulder piece cover, and described block is provided with notch III, and the depth H of notch III is greater than the height h of lining to be removed.
Dismantle the method to belling shoulder piece cover, utilize above-mentioned extracting tool, method is as follows:
1) on the inner hole wall of lining II, asymmetric buff goes out two grooves corresponding with the arc boss on jacking block I;
2) lining I is dismantled: outer rim block being stuck in lining I, bolt one end is connected with nut II, the other end is successively through block, lining I and lining II, nut I is installed in the notch I of jacking block I, then the other end of bolt is installed to together, the arc boss of jacking block I falls into the groove that lining II polish, jacking block I advances along the groove in lining II, make it the end contact with lining I, turn nut II with spanner, lining I ejects in the notch III of block by the thread transmission utilizing bolts and nuts II to form;
3) lining II is dismantled: outer rim block being stuck in lining II, bolt one end is connected with nut II, the other end is successively through block and lining II, nut I is installed in the notch II of jacking block II, then be installed to the other end of bolt together, jacking block II advances along matrix hole, makes it the end contact with lining II, turn nut II with spanner, lining II ejects in the notch III of block by the thread transmission utilizing bolts and nuts II to form.
The invention has the beneficial effects as follows: dismounting mode of the present invention is owing to adopting thread transmission, and in bushing dismounting process, thrust transmission is even, steady, avoids matrix hole inwall impaired in unloading process.Meanwhile, the thread transmission that forms owing to utilizing bolts and nuts dismounting lining, required working space is little, be more suitable at narrow space region dismounting lining.Successfully will be exited belling shoulder piece cover by the present invention, exit rear matrix hole size and surface roughness is kept intact, do not change, serviceability rate reaches 100%, to solve on aircraft or other products precisely, a difficult problem that convenient, dismounting and change is overlapped belling shoulder piece.
