Adjustable circular optical device positioning fixture

Abstract

The invention discloses an adjustable circular optical device positioning fixture. The adjustable circular optical device positioning fixture comprises adjustable clamping blocks (1), wherein a single side or dual sides of the adjustable clamping block (1) are provided with semicircular holes which are distributed uniformly; the plurality of adjustable clamping blocks (1) are assembled together, so that corresponding semicircular holes in adjacent adjustable clamping blocks (1) are combined into workpiece holes (2); the positioning fixture constructed by the plurality of adjustable clamping blocks (1) is provided with a mandrel hole (3); a mandrel (4) is inserted into the mandrel hole to fix the plurality of adjustable clamping blocks (1) in order to construct the positioning fixture; the workpiece holes (2) can accommodate workpieces of different apertures by adjusting the tightness of the mandrel (4). In the positioning fixture, the workpiece holes (2) can accommodate the workpieces of different apertures by adjusting the tightness of the mandrel (4), workpieces to be machined are prevented from moving and deviating in a machining process, and ports of protruding ends of the workpieces can be ground or polished stably, so that the requirement on machining quality of the workpieces to be machined is met.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an adjustable circular optical device positioning fixture capable of accommodating workpieces with different apertures. Background technique [0002] A fixture is a device that precisely supports, positions and clamps one or more workpieces to facilitate the processing, grinding, and cutting of the workpiece, or as a device for assembly, inspection, etc. The fixture can be used in a large number of The production is in the middle, reducing the waste of working hours, improving production efficiency, maintaining product quality and reducing defective rate. Although the fixture itself does not have the function of grinding and cutting, it can accurately locate the workpiece at a certain position, and firmly clamp it to this position to withstand the force applied by the tool during processing. A device used to fix the processing object in the production process so that it occupie...

AI Technical Summary

Problems solved by technology

The existing positioning fixtures for circular optical components can only be used to position optical components with a fixed aperture, and the corresponding positioning fixtures must be replaced when grinding or polishing the protruding end port of each optical component, so it is necessary to make multiple Only the positioning fixture can meet the requirements of use, which is costly and wastes time and space
