Description

The invention relates to a tool for machining parts by surface plastic deformation.

The purpose of the invention is to decipher the technological capabilities of the tool by machining stepped surfaces.

FIG. 1 shows a schematic representation of the proposed instrument, a general view; FIG. 2 is view A; in fig. one; in fig., - 3 - section bb in fig. 2; in fig. 4 is a section on BB in FIG. 2; in fig. 5 - tool position and processing.

The smoothing tool contains a holder 1 with a three-sided insert A fixed on it with the help of a screw 2 and a sticking edge 3 installed at an angle of 45 ° to the axis of the holder 1. The working part of the insert is formed of a series of dbm surfaces: two flat surfaces 6 and 7j |, which in turn cylindrical surfaces 8 and 9 are mated with the non-working part 10 of the insert 4. The central cylindrical part of the fr /

with two spherical parts 1V, which, in turn, are mated with conical surfaces 12, with flat surfaces 6 and torus surfaces 13, the latter being mated with cylindrical surfaces 8 and 9. The radii of the central cylindrical part, spherical cylindrical and torus surfaces are equal to each other.

In operation, the tool is secured by the holder 1 in the machine caliper and is guided to the machined surface of the stepped part. A deformation force is applied to the tool and the cylindrical surface is successively applied to the flat surface of the insert and the transition surface to prices, the cylindrical part 5 and the torus surface the flat surface opposite to that mentioned above. Depending on the shape of the workpiece, flat, conical torus and spherical surfaces of the insert may enter into operation.
