Abstract

The invention relates to the field of optical production technology and can be used in optical machines for polishing the surfaces of elliptical optical cylinders. The aim of the invention is to improve the accuracy of polishing of the surfaces of elliptical zipingrs by ensuring that the working surfaces of the instrument are in constant contact with the workpiece surface while they are constantly forced by force. The tool comprises a housing 1c attached to its base surfaces by polishing substrates 2 and with a holder 3; The base surfaces of the tool body 1 are made in the form of two planes arranged at a right angle to each other. The center of the ball bearing is located on the line of intersection of the working surfaces of the polishing substrates, and the holder is us-mounted in the tool body 1 with the possibility of adjusting its height - moving the angle formed by the working surfaces of the substrates along the bisector. 1 il. i (L

the polishing pads 2 are reinforced, and the holder 3c is cavity 4 In case 1, a threaded hole 5 is made in the case 1 along the bisector of the angle between the base surfaces A, into which the holder 3 is screwed. Ball bearing (ball) 6 of the machine 7 lead (not shown) enters the cavity 4 holders 3. The position of the cavity 4 of the holders 3 in the device body is height adjustable and fixed by a nut 8.

The device works as follows.

Adjust the preliminary position of the holder 3 in the housing 1 of the device in height. For this, knowing the geometrical parameters of the polished elliptical billet, set the required distance of the ball bearing 6 with the help of a caliper to the geometric axis of rotation of the billet. The final adjustment of the position of the holder 3 in the device body 1 is carried out by placing the device on the machine by screwing in or unscrewing the holder 3 from the device body 1 to a position in which the device does not oscillate in a direction perpendicular to the axis

rotation of the workpiece 9 when it is polished. This position of the holder 3 is fixed by a nut 8. Then the forced reciprocating movement is reported to the tuned device in a direction parallel to the geometric axis of rotation of the workpiece from the drive, and the workpiece 9, fixed at the centers, is driven at a frequency y around its geometric axis from the second drive (not shown). The leash 7 of the machine through the ball 6 transmits the device the force of the clamp F to the workpiece surface from the feed mechanism of the machine.

The polishing slurry is fed to the treatment area by the machine feeder.
