Detailed Description
The invention aims to design and manufacture a device for polishing the surface of a small-sized sheet part, which is used for processing the surface of a special-shaped small-sized sheet part, and effectively avoids the defects that the part is small and thin and is inconvenient to clamp, and the heat transfer is too fast and the operation cannot be directly carried out by hand contact.
The method specifically comprises the following steps:
a surface polishing device for special-shaped small sheet parts comprises a base 1, a groove plate and a fastener; the groove plate is arranged on the base 1, the piece to be polished is arranged on the groove plate, and the fastening piece is arranged on the base 1 and the groove plate and used for fixing the piece to be polished;
the fastener comprises a right-angle plate 3, a stop block 4 and a sample block 2; sample block 2 sets up in recess board top, and the both ends of sample block 2 are passed through right angle board 3 and are fixed on base 1, and dog 4 sets up the side at base 1.
The groove plate comprises a first metal plate and a second metal plate, an opening matched with the piece to be polished is formed in the first metal plate, and the first metal plate is welded on the second metal plate.
The first metal plate is provided with two symmetrical openings, and the first metal plate is welded on the second metal plate to form a groove plate.
The purpose of the invention is realized by the following technical scheme: in order to facilitate the surface polishing of small-sized thin-sheet parts, the outline of the part is cut on a metal plate with the thickness equal to that of the part by adopting wire cutting, then the metal plate is welded and fixed on a thicker metal plate, so that a groove with the outline of the part is formed, the small thin-sheet part is fixed in the groove, the surface to be polished is taken down, and the small thin-sheet part is fixed again for polishing the other surface after being overturned.
The invention has the advantages that: fix small-size thin slice part and conveniently grip the operation on specialized tool, utilize metal sheet to transfer heat fast characteristics simultaneously, inlay the part and laminate with it, can dispel the heat fast and avoid part polishing process heat accumulation and appear the burn. The part 2 can be replaced according to the shapes of different parts, and is convenient and easy to operate.
The embodiment is as follows:
after a guide pipe is installed in a guide vane cavity of a high-pressure turbine of a certain engine, a hole at one end is sealed by a cover plate in a welding mode. The cover plate is formed by cutting a profile from a bar stock according to a drawing by a linear cutting line, and then the profile is cut into sheets with the thickness of about 1mm one by one, and because the welding quality is considered, no machining trace residue exists on the surface of a part, and a remelted layer needs to be removed from all the surfaces. The operation steps are as follows: two cover plates to be polished are arranged in the two grooves in the figure 1 in a symmetrical mode, then the sample block 2 and the part penetrate through the right-angle plate 3 to be arranged in the base 1, and the upper surface of the part can be polished after one side of the sample block is attached to the stop block 4; after the polishing, the sample block 2 and the parts are taken out of the base 1 together, and the cover plate is taken out, turned over and reloaded into the grooves at the symmetrical positions of the sample block 2 to polish the other surface.
