Abstract
The utility model discloses a hard fiber product image displacement detecting device which comprises a pedestal, a mobile locating piece, a workpiece top plate and a top plate block. The center of the pedestal has a central hole. The mobile locating piece is fixed on the pedestal. A front end of the mobile locating piece has a through groove composed of a rectangular groove and a V-shaped groove. A front end part of an inner wall of a through groove is provided with a spring. The top plate block is fixed at a corresponding end of the pedestal. The workpiece top plate is installed between the top plate block and the mobile locating piece. A vertical transverse plane of the top plate block has a screw hole, and an adjusting screw knob is installed in the screw hole. According to the hard fiber product image displacement detecting device, detection on image displacement is carried out with a cylindrical surface of a fiber element as the reference, so that a fact that measurement errors are caused as the cylindrical surface is not vertical to a transverse plane is prevented. The hard fiber product image displacement detecting device is convenient to operate, accurate in measurement, and suitable for detection on workpieces on a large scale, and plays an active role in controlling the production process.
Description
Technical field
The utility model relates to hard fibre optic image transmission product image displacement pick-up unit.
Background technology
Low-light level imaging technology is take photon---photoelectron is the information carrier of scene image, the principles such as external photoeffect, electron multiplication and electric light conversion based on device, to the scenery under night sky faint light or the illumination of other non-visible lights, carry out image capture, conversion and enhancing, be finally shown as the visible image of human eye.Low-light Level Night Vision Technology claims again image intensifying technology, the structural principle of image intensifier is fibre faceplate input window---input faint optical imagery, photocathode---convert faint electronic image to, microchannel plate---strengthen electronic image, video screen---form the visible optical imagery of human eye that output strengthens.Video screen is exactly to plate fluorescent powder on hard fibre optic image transmission element, and fluorescent powder electroluminescence is by the visible optical imagery of fibre optic image transmission element output human eye, and its biography is most important as performance.
Image displacement---take the right-angled intersection point by optical fiber image guide device input end face center as benchmark, the largest global displacement from the viewed figure of output end face with respect to this benchmark.The main cause that its produces is in optics process, and mechanical axis and optic axis do not overlap and cause.Along with the day by day maturation of night vision technology, require more and more higher to components and parts product quality.For example: the image displacement of optical fiber image inverter rises to 125 microns by original 250 microns.Improve the accuracy of detection of fiber optic component image displacement, so that more effective quality of production control is very necessary.Conventional detection method is: columniform fiber optic component is placed in circle detection ring and rotation is found out maximum displacement and measured, this method of testing requires element end face necessary vertical with cylinder, so just can measure accurate image displacement amount.In actual production run, a large amount of blanks can not guarantee that end face is vertical with cylinder, and to production run, control exists relatively large deviation.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of hard fiber products image displacement pick-up unit of avoiding bringing due to cylinder and end face out of plumb measuring error.
In order to solve above technical matters, the utility model by the following technical solutions.
A kind of hard fiber products image displacement pick-up unit, comprises base, running fix piece, workpiece top board and top board block, and described base middle part has center pit; Running fix piece is fixed on base, running fix piece front end has the groove by rectangular channel and V-shaped groove combination, groove inwall leading section mounting spring, top board block is fixed on base corresponding end, between jacking block baffle plate and running fix piece, workpiece top board is housed, top board block is vertically having screw on end face, installs and regulate spiral shell button in screw.
When work, the utility model pick-up unit is arranged on projector worktable, regulate the adjusting spiral shell button on jacking block plate washer, workpiece can be rotated in the groove of running fix piece, but can not extract, to guarantee that in workpiece cylinder and groove, two V faces are close to, turning of work piece, find the graticule axis parallel with the groove limit of base maximum offset in one direction, regulate projector platform, this axis is overlapped with in cross curve on projector display screen one, allowing projector displacement show makes zero, turning of work piece again, find graticule axis at reciprocal peak excursion point, measure numerical value divided by 2, obtain the image displacement of this workpiece take cylinder as benchmark.
Hard fiber products image displacement pick-up unit described in the utility model, take fiber optic component cylinder as benchmark, image displacement is detected, so just avoid the measuring error of being brought by cylinder and end face out of plumb, easy to operate and value is accurate, be applicable to workpiece sensing in enormous quantities, to production run, control plays a positive role.
