Abstract

The invention relates to a technology for the manufacture of optical parts, can be used to process spherical surfaces of optical lenses, and allows an increase in the productivity of processing by automating the process. In order to do this, during the processing of a large product or block, the embracing evil 4 is pressed against the outer surface of the upper part of the dorsing expansion cone 1 with the aim of the un. it stiffens its petals by supplying compressed air to pneumatic chamber 10, the rod of which at the same time presses the plug on the roller acting on the element 4, lowering it on the cone 1. When the tool 12 is withdrawn, at the end of processing it with its disk 13 rests on the inner surface of the lower part of the split cone 1, which allows the tool 12 to be separated from the machined surface and held in the tool. The np :: need to replace the tool 12 covering element 4 is retracted upward, removing compressed air from the pneumatic chamber 10, thereby reducing the elasticity of the petals of the split cone I, and tool 2 is fed downward (for example, by gripping the manipulator). In this case, the disk 13 expands the petals of the split cone, releasing the stem of the tool from the tool. 2 Il. S

The purpose of the invention is to increase productivity by automating the process.

FIG. 1 shows the device section; in fig. 2 shows section A-A in FIG. one.

The device for processing optical parts consists of an elastic clamping element 1, made in the form of a split double-sided cone, mounted on the spindle 2 by a nut 3 and having the possibility of axial reassembling, an additional female element 4 installed with the possibility of axial movement along the slots 5 and spring-loaded 6. The rollers 8 of the drive fork 9 connected to the pneumatic chamber 10 and the spring-loaded return spring 11 enter the annular groove 7 of the element 4. Petals of the clamping element 1 during operation ontaktiruyut with broken surface of the tool 12 provided with a disk 13, a mismatch axes tool 12 and the workpiece 14.

The device works as follows.

In the process of forming a part, the device works similarly to the prototype, except that when processing a large product or block, the surrounding element 4 is pressed against the outer surface of the upper part of the double-sided split cone in order to increase the stiffness of the petals not by preliminary manual adjustment, but by supplying compressed air to pneumatic chamber 10, the stem of which at the same time presses the drive fork 9, with its rollers 8 acting on its additional female element 4, which in this case descends along the Itzam

5 split cone, squeezing its petals, which allows you to adjust the stiffness of the petals by changing the pressure of compressed air in the pneumatic chamber 10.

At the end of the treatment, the female element 4 is also pressed by means of a pneumatic chamber 10 to the cutting cone. Then the device together with the spindle 2 is retracted upwards from the part 14. At the same time, the tool 12 with its disk 13 rests on the inner surface of the lower part of the split cone, tearing away from the part 14 as the device is further raised. Next, the compressed air from the pneumatic chamber 10 is removed, the return spring 11 retracts the plug 9 to the down position, and the spring

6 returns the female element 4. To the extreme upper position until it stops. If necessary, change the tool 12, the latter is fed down (for example, by gripping the manipulator). In so doing, the disk 13 expands the petals of the expansion cone, and the tool 12 is removed from the tool. In order to install a new tool, it is fed up to the device, and the disk 13, pressing the rounded edges of the petals of the split cone 4, pushes the latter and falls into the device, spontaneously dropping it from where it prevents the elasticity of the petals.
