A device for treating the cnv-linear surfaces of optical lenses, the first, one | one and the other, is known, based on the part holders mounted on it and on the rim. -1e :. The tool is mounted on a spherical support located in the center of the curvature of the surface being machined and connected with an actuator made in the form of partial chambers mounted evenly around the tool and connected to the pressure source through the distributor (1 |.

However, due to the wear of the H-base support, the installation of the deformation of plastic chambers, the presence of yiipyiHx g elements and elements, it does not ensure the accuracy of machining, y.iajTHbie does not work, but it reduces the handling of the skin, and it is as if it is used to change the processing,), it is the way to get, and get the values, and to get the values, and get the way to get the values, and get the way to get, and so, you have to do so), and you need to change the number of items that are out of work, y.iajTHbie on ruzknn, which reduces the processing of the body, it is necessary to get to the table, it is the same thing as if it is used, but it does not change the processing,), and to get to the row,), it is the way, and it will be; the process of sleep) has been solved with significant difficulties, since the shrinking and compressing of the hN111H kame) in this case will be the meaning, 1Ы1о b (). 1yne. What is required for maintaining the tool with the frequency required by the machining. The increase in the first love of 11.1111 of the environment is brought to the 1st level of the 1st.

Le.; I () bretenn - a new quality of the process .a 11 due to the 1-; emea frequency of reciprocating frivolous tooling | The goal is achieved by the fact that a device containing a base with a tool holder mounted on it, mounted on an oiore located in the center of the curvature of the surface to be machined and connected to the swinging mechanism, is made in the form of a two-cavity drum, into the internal cavity of which the medium is fed pressure, prnv h1a in motion through the tangential element, located in the partition between the inner and outer cavities of the drum, the inertial mass, located in the | The drum is installed on the blade support and is connected to the base by means of elastic elements.

FIG. 1 shows the proposed device, an axial section; in fig. 2 - section .4 - A in FIG. I.

The device for treating the surfaces of ontic parts contains a tool 1, located below the workpiece 2, rigidly connected with the mechanism of relative swinging motion, made in the form of a two-cavity drum 3, in the inner cavity 4 of which there is an inlet Kaiia.i food under pressure. With SITOM, the inner cavity is connected to an annular outer cavity 6 with tangentially located nozzles 7. An inertial mass 8 is located in the outer annular cavity 8. produced in the form of a Japica, having spine move but ko.1ieioy KJ.KXTH (. which ful, you 1pen (1 skno1 kama.m 1d. The drum 3 with the tool I installed

on the support 10, screwed into the drum axle 11 and fixed by a nut 12, supported on the support 13, mounted on the base 14. The drum axle 11 is connected to the base with springs 15. The workpiece 2 is connected to the actuator 16 in turn and with the help of a spring 17 with a base 14. The working force during operation is a spring 17.

The device for processing the surface of the ontic components works as follows.

Simultaneously with: iTiiM but the inner cavity 4 of the drum 3 feeds through the inlet channel 5 under the pressure of the working medium, which through the steam guns of the air nozzle between the inner 4 and the outer 6 G1o, 1 of the Marabian 3 nozzles 7 enters the annular rigging cavity b, exerting pressure on the line | the mass of 8, made in the form of a ball, and drive it into motion. The internal medium is withdrawn from the annular cavity B through the outlet canal; | 9. When the inertial mass 8 is moving along the annular cavity h, the center of gravity of the drum 3 is intermixed with the tool I. As well as the change in direction arises from the movement of this mass, the inertia force. which causes the drum 3 with the tool I to deflect, due to the effect of inertial force in the plane, perpendicular to the plane of the line of contact of the knife bearing 10 with the subtitle 13, turning the tool itself around the tool. At the same time, the deformation of the springs 15 is occurring;

To ensure guaranteed processing of the entire surface of the workpiece, it is necessary that the amilitude of the co.chebie tool.ment exceeds the distance between the centers of neighboring workers (diamond) e, 1.the tool’s tool diameter, 1yn) 5 cross section, i.e. Banip D |.). to be more than (fng. h. -th ..- 2-, g.

The pressing force of the workpiece 2 to the working surface of the tool 1 is carried out with spring nominal 17. The presence of the threaded connection of the support K) and the drum axis 11 allows changing the radius of curvature of the machined sphere.

After the machining is completed, the part 2 is retracted from the tool 1, the motor is switched off, a new workpiece is installed and the cycle is repeated.

The use of the proposed construction allows to achieve an increase in the quality of processing and an increase in the productivity of the process.
