Description

The invention relates to the surface treatment of parts by surface plastic deformation and can be used to process the cylindrical surfaces of the holes of the parts.

Known rolling for machining cylindrical holes of parts, on the casing of which are installed with the possibility of rotation in the longitudinal plane of rolling with respect to the axis perpendicular to this plane, spring-loaded holders with Deforming elements, mounted for movement in the radial direction, associated with the holders of fixation. a spring-loaded stop for engagement with the face of the part and a latch, which is interoperable, with said spring-loaded stop 1.

However, the deformation force developed by each of the deforming elements is different, which does not ensure the uniformity of the hardened layer and reduces the quality of the treatment. i.e. the invention is an improvement in the quality of processing. by providing a uniform surface layer. . The goal is achieved by rolling the inner cylindrical surfaces, comprising a housing with shafts mounted on the housing rotatably relative to the axis of the shank, spring-loaded holders with deforming elements mounted for movement in the radial direction, a locking mechanism associated with the holders and a supporting spring-loaded stop, designed to interact with the face of the part, a latch arranged to interact with the said subs uzhinennym focusing, the tool holder is provided with a through hole holders deformation elements mounted eccentrically relative to the shank axis and with the possibility of rotation, the spring holders deforming element is disposed in the through hole between the holder and the pawl is fixed on the tool holder.

On ig. 1 shows the rolling, general view; in fig. 2 shows section A-A in FIG. one.

Rolling includes a housing 1, on which is installed with the possibility of rotation in the longitudinal plane of rolling along axis 2, perpendicular to this plane, the holder 3 with the forming elements 4, spring-loaded in the radial direction, and the mechanism for their fixation 5, connected through a system of levers 6 and 7 with a holder 3. The latch contains an emphasis 8, made in the form of a bearing fixed on 6. The lever 7 rotates on the axis 9 and presses against the limiter 10 by the spring 11. The lever 7 interacts with the lever 13 installed on the axis 12, the spring 14 pressed to the lever 7. The lever 13 interlocks with the latch 15 fixed on the holder 3 in the through-hole which houses the springs 16 and 17, mounted between the holders 18 of the deforming elements, each of which is made in the form of a bearing with a machined N. outer ring. The bearings are mounted on axles 19 placed on the forks of the holders 18. The stability of the outer ring of the bearing is ensured by the washer 20 and the thrust bearing 21 controlled by it, the springs 16 and 17 interact with the holders 18. The radial movement of the holders 18 is limited by the stop made in the form of studs 22 and nuts 23.

Works rolling as follows.

Usually, the machining of the part installed in the machine chuck (not shown) is specified by the displacement. Rolling is introduced into the hole of the part, and the deforming elements 4 are machined. After the whole surface is processed, the deforming elements 4 are withdrawn from the hole of the part, the stop 8 comes into contact with the face of the part and, when further moving the rolling, takes out the rolling; . from the engagement with the latch 15, the lever 13. The holder 3 with the deforming elements 4 rotates under its own weight around the axis 2, and in this position of the holder 3, the rolling is taken out of the machined hole.

The proposed rolling for processing the cylindrical surfaces of the holes of the parts as compared to the prototype makes it possible to obtain a uniform surface layer on the part, since it is possible to create the same deformation force by each of the deforming elements.
