The invention relates to metalworking and can be used in the finishing processing of the internal cylindrical surfaces of the parts in question I n and n.

The purpose of the invention is to improve the quality by correcting the deviations from the straightness of the axis of the surface being treated.

FIG. 1 shows honing.: 1 on head, longitudinal section; in fig. 2 the same cross section; PA of FIG. 3 is a scan of a set of levers with bar holders fixed to them; in fig. 4 scheme for correcting the initial form of the form.

In the case of the honing head I, three rushes of radial grooves 2 and a central hole 3 are made. In each of the grooves there are mounted (bar bars 4 6 with abrasive bars 7. Between each bar bars 5 are the middle wheel and two diametrically opposed to it) b) code | ) reap. 1 and 4 and (i) extreme kines, the kinematic connection is provided by means of -shaped levers 8. A compensating mechanism 9 is installed in each of the bar holders S and is a pre-compressed elastic elceptor I) and a wedge I, preloaded by a spring 12. Placement pi) The i4aiOB 8 in the housing 1 is provided with a b / 1 year of their shape (Fig. 3), representing the sections of the thick-celled pilpdra, combining two differently designed screws 1) 1e branches.

The correction of the deviation of the axis of the machined surface from the straightness of the 11 gauge () honing head is shown schematically in FIG. 1, where their section is given by the length of a transverse axis, which passes through a curved axis. Groups but three bars, connected by one m lever, can pic-. It is advantageous to take on the basis of the treatment of the () th surface of positions 13 and 14. In 13 b) the middle tusk rests on the trough of the treated surface, and in position 14 on the tilt.

Heading works as follows.

In the right position, wedge I 1 iiaxo-diggs and be1) are in the position, and bar-shaped. 1 and 4 6 ustan.chpy on mpiima.lny diameter | alyy size. In the process of processing, during group 13, three bars pass through,: | burn 13, characterized by one diameter and one diameter;) dimension di, K. IHH 1 1 is lowered under the action of spring 12, ensuring the dilution diameter of the bars equal to .Meter processed surface NOSI. I) and the far turn of the honyneve, 1n () th 10,: block bars for 1) position 14, characterizing the use of eleven diameters of di. As a result of the compression of the bars to the diameter you are. enhanced

the radial component of the cutting force, and the scaling of the prestressed element 10, ensures that this force is limited to the optimal value. The installation of a sensing mechanism in each of the middle bar bar holders allows for the production of one group of all groups connected (P) 1x to three bar bars.

, The implementation of levers in the form of sections of a thick-walled cylinder, combining two oppositely directed screw branches, allows all the levers to be placed inside the hull without reciprocal contact, thus ensuring the autonomy of adjusting bots of each group of three bar holders.

Investigation of intensity by the discovery of junenp (h and the machined surface ol of the linearity is provided on the first kinematic connection between co0 (corresponding b) bars, and the realization of this link in the design is achieved by using |) iji4ai B of the specified form and installation in b) accelerator; medium-ruler compensating mechanisms.

Thus, the ICP of the metal of the steel, the tin is automatically provided for the variable depending on the allowance, the floor is removable, and in places with mipima,; |

From this it follows that the head provides the mouth () of the axis oi from the axis from the direct linearity at a time of removal of the peace of the small allowance, and the intensity of the kapzapun run-penostat and the exact 1b o6) a6 (jTKH.
