SU408754A1 - CUTTING MACHINE FOR CUTTING SPHERICAL DIFFRACTIVE GRATINES - Google Patents

Description

one

This invention relates to cutting diffraction gratings on dividing machines.

Electromagnetic correction machines are known for raising and lowering a cutting tool for applying strokes, containing separating and cutting carriages. A disadvantage of the known machines in the manufacture of spherical arrays with large apertures is that when the cutter head is idle, the gap between the raised cutter and the surface of the workpiece changes, which leads to the formation of chipping on the cutter blade and the knocking out of the workpiece when the tool is dropped on the workpiece. and, therefore, reduces the quality of the cut.

The aim of the invention is to maintain a constant gap between the cutter and the surface of the workpiece when the cutting head is idling.

The goal is achieved by the fact that the dividing machine is equipped with kinematically connected between them a cutting width copier mounted on the dividing carriage, a stroke length copier interacting with a pusher connected to the electromagnet.

Pa drawing shows the proposed machine.

The cutting carriage 1 is horizontally moved to the arm 2 of the body 3 of the machine. The tool holder is hinged at point 4 at the point of attachment of the tool holder with the tool 6 for applying strokes.

In the vertical guides 7 of the carriage 1, the electromagnet 6 is movably mounted that controls the raising and lowering of the toolholder 5. The electromagnet is rigidly connected to the pusher 9, which interacts with the cam 10,

the length of the stroke, movably mounted in a vertical. Konir 10 through the siete.m levers 12, 13 kinematically connected with the pusher. 14 a copy of the cutting width 15, mounted on

the separating carriage 16, which carries the workpiece 17. Before starting the idle stroke of the incisal capeTKii 1, the electromagnet 6 is turned on, as a result of which the tool holder 5 nitrite is pushed to the electromagnet core,

Thereby, the cutter 6 is above the workpiece 17. During idling, the pusher 9 slides over the copier 10, as a result of which the cutter 6 moves along a path repeating the curvature of the workpiece 17 in the corresponding section. When turning

dividing the carriage 16 in the process of dividing the lattice 17, the copier 15 through the pusher 14 and the levers 12, 13 moves the coiir 10 into the caster 11, and with it the pusher 9 with the electromagnet 1, the toolholder 5 and the resolver 6. B

As a result, the gap between the raised cutter and the workpiece remains constant all the time.

Subject invention

A separating machine for cutting spherical diffraction gratings placed on a dividing carriage containing a horizontally moving cutting tool carriage on which a vertically mounted electromagnet is installed that corrects the raising and lowering of the tool holder, which is different in that it has a constant clearance between the tool and the tool blanks when idling the cutting carriage, the machine is equipped with a cutting width kinematically connected with a copier mounted on a dividing carriage and a copier the length of the stroke, interacting with the pusher connected to the electromagnet.
