Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a positioning system for an inner circle cutting fixture, which is used for the scheme of precisely controlling the verticality of adjacent cutting edges of an inner circle cutting machine. The principle related to the angle of the groove direction relative to the incident surface is used to monitor the positioning of the tooling fixture, which solves the problems of low precision and insufficient stability of the existing inner circle cutting fixture and cannot be monitored in real time

Abstract

The invention provides an inner circle cutting fixture locating system and method. The clamping fixture and a device support are arranged at a certain interval side by side; a raster element fixture is provided with a plane used for fixing raster elements, and an included angle of 90-180 degrees is formed between raster slot directions of adjacent raster elements; the raster element fixture is fixedly arranged on the clamping fixture, the plane of the raster element fixture is parallel to the plane of the clamping fixture, and the plane of the raster element fixture can rotate around a center shaft; a single-wavelength laser, a reflector, a scale plate and a monitoring camera lens are fixedly arranged on the device support, the reflector is fixedly arranged at the light beam exit direction of the single-wavelength laser, the reflector changes light beam directions of the single-wavelength laser and the raster elements, and diffraction lights produced by the raster elements are incident onto preset scale lines of the scale plate; and the monitoring camera lens is used for monitoring positions of the scale lines of the diffraction lights on the scale plate. The inner circle cutting fixture locating system and method have the advantages that the perpendicularity of adjacent cutting edges is improved, the perpendicularity control stability is improved and the cutting cost is lowered.

Description

technical field [0001] The invention relates to a laser and grating indicating measurement system, in particular to a positioning system and method for an inner circle cutting jig. Background technique [0002] Most of the traditional optical cold processing products need to go through the cutting process during the processing. For example, cutting the glass blank to a machinable size, cutting the semi-finished product into a finished product, etc. Since optical products have relatively high requirements on size, angle, edge chipping, etc., cutting equipment usually has relatively high requirements. The common cutting equipments are horizontal inner circle cutting machine and vertical inner circle cutting machine. [0003] When the horizontal internal circle cutting machine cuts the product, its angular accuracy is usually guaranteed by the mechanical fixture, especially the verticality of two adjacent cutting edges, which is completely guaranteed by the cooperation of the...
