Detailed description of the invention
Embodiment 1 one kinds of grinding attachments for thin wall component endoporus
As Figure 4-Figure 6, a kind of grinding attachment for thin wall component endoporus, is made up of grinding machine (1), fixture (3), emery wheel (4), pole wheel (5) and motor (8).
The two ends of grinding machine (1) are shaped with bearing I (6) and bearing II (7).
Fixture (3) is fixed on bearing I (6) by three-jaw chuck (9), motor (8) is fixed on bearing II (7), motor (8) is connected with pole wheel (5), emery wheel (4) is arranged on pole wheel (5) front end, and motor (8) drives emery wheel (4) opposed jaw (3) to axially move by pole wheel (5).
Described fixture (3) is annular, the cylindrical of one end is shaped with outer lug boss (3-1), the inner circle of the other end is shaped with inner convex platform (3-2).Fixture (3) is shaped with breach (3-3).Described fixture (3), the coaxiality error of cylindrical and inner circle is within-0.02 ~+0.02mm.
Grinding attachment for thin wall component endoporus of the present invention, is greater than Ф 100mm for diameter, and thickness is less than the thin wall component inner hole grinding skin processing of 2.5mm.Fixture (3) adopts No. 45 steel, heat treatment 35-39HRC.Operation principle is: fixed by part outer by fixture, is arranged on by fixture on grinding machine, carries out the inner hole grinding of part after folder is stable again with emery wheel.Creativeness of the present invention is to locate employing 360 ° of comprehensive location, clamping force is disperseed, prevents part from occurring flat phenomenon.Because needs carry out clamping parts by fixture, in order to reduce transition position error, so require that the axiality of fixture inside and outside circle is within 0.02mm.Simultaneously in order to make parts fixation stablize, the laminating degree of fixture inner circle and part outer requires very high, so by the dimensional tolerance design of fixture inner circle and part outer within 0.02mm, while at fixture cylindrical place incision 4mm fracture, facilitate the handling of part.
