The optical mirror slip processing tool

Technical field

The utility model belongs to the optics cold processing technique, relates to a kind of undersized optical mirror slip processing tool.

Background technology

General optical element (like prism) processing mode be applicable to when optical mirror slip is larger-size, and precision is lower for becoming dish processing.But for the small size eyeglass; Like Faraday substrate as the core component of laser gyro; Its technical requirement is many, part is little and required precision is high; Actual processed complex, particularly the eyeglass for low-angle (about 20 minutes), micro parts (less than 10mm) adds man-hour, does not have the possibility of using for reference basically.

Owing to the factor of blockade on new techniques and secret aspect, do not appear in the newspapers in the document that laser gyro Faraday substrate processing technology is at home and abroad published simultaneously.In the processing of initial cavity, employing be whole angle gauge block polishing, each part is placed on the inclined-plane, actually adds man-hour, because each part height is different, need carry out asymmetric grinding, is difficult to guarantee the uniformity of part thickness.Yet because substrate thickness is had requirement, resultant processing parts physical dimension qualification rate extremely low (10%), and also the part of being processed exists angle discrete, is difficult to guarantee angle precision, simultaneously, adds man-hour, needs handwork, and labour intensity is big.

Summary of the invention

The purpose of the utility model is: propose a kind of machining accuracy height, the fast optical sheet processing tool of efficient.

The technical scheme of the utility model is: a kind of optical mirror slip processing tool, its bottom surface are the plane, and upper surface is regularly arranged serrated face array; Wherein, each serrated face oblique angle is consistent, and waits height; Wherein, the distance between each serrated face is not more than 10mm, and the oblique angle is not more than 2 °.

Said eyeglass processing tool is by bonding the forming of low-angle slip gauge of the same size of some shapes, and wherein, the inclination angle of each low-angle slip gauge is the serrated face oblique angle.

The angle uniformity at the inclination angle of each low-angle slip gauge is not more than 2 ".

The specific embodiment

Explain further details in the face of the utility model down.

The utility model optical mirror slip processing tool is an example with processing faraday optically-active substrate, the oblique angle A of low-angle slip gauge is processed into and the identical cuboid in first oblique angle of part, wherein; This oblique angle is 2 °; Angular error 2 ", each piece angle high conformity of while, the required angle uniformity is 2 " in.In addition, its lap of low-angle slip gauge guarantees to be that orthogonal plane, particularly its side and bottom surface are strict vertical, monolithic bottom surface perpendicularity 2 ", angle is 90 ° ± 2 " in, the height error of each little slip gauge is in 0.001mm, and is as shown in Figure 1.

Be benchmark then with the plane, the low-angle slip gauge sticked with glue the row of being connected into constitute faraday's optically-active substrate processing tool, like Fig. 2; Its side is a zigzag, and the frock bottom surface that is become is strict plane, and its flatness is less demanding in 0.001mm; Simultaneously; The highs and lows of each low-angle slip gauge remains on the same horizontal line, i.e. height such as the corresponding each point of each low-angle slip gauge, the unanimity of thickness when guaranteeing part processing.

See also Fig. 3, it is the overall structure figure of the utility model optical mirror slip processing tool, and its upper surface is the array structure that regular serrated face is arranged, and is used to place part.As shown in Figure 4, it is the part assembly drawing of said Faraday substrate processing tool, and said part is bonded on each serrated face of frock; Each part tilts to place; Guarantee parallel first machining angle A that can form part of part and slip gauge bottom surface, the height such as each part relevant position on the whole frock of while, thus one adds man-hour; Can effectively avoid the discrete appearance of machining angle, guarantee the uniformity and the machining accuracy of part processing.

In addition, bonding low-angle piece uses the composition of glue to be DG-4, and joining the glue ratio is 3: 1.Naturally it is dry to place glue-line after the bonding completion, then slip gauge integral body is put into 100 ℃ of constant temperature of incubator 2 hours, naturally cooling.And the utility model faraday rotator substrate processing tool is in order to process the part that different angles require, and combination can bond the low-angle slip gauge at different oblique angles.Be processed into than second big 2 times angle in oblique angle of part i.e. 2A, angular error 2 like oblique angle with the low-angle slip gauge ", its lap guarantees to be orthogonal plane, angle 90 ° ± 2 ".The height error of each little slip gauge is in 0.001mm.With angle is that the slip gauge of 2A is combined into integral body, and mode is with last identical.The grinding and polishing part guarantees parallel second angle A that can form part of part and slip gauge bottom surface, and after the completion of processing, part promptly forms symmetrical angle A, and the two sides angle is 2A.

Certainly, the utility model optical mirror slip processing tool can be processed other optical base-substrates of small size (less than 10mm), low-angle (about 20 minutes), is not limited to the Faraday substrate.

The utility model optical mirror slip processing tool has been realized from the transformation of whole angle gauge block processing mode to combination angle gauge block processing mode; On the basis that guarantees machining accuracy; Greatly improved physical dimension qualification rate (100%), improved working (machining) efficiency, reduced labour intensity.Particularly during grinding and polishing, can evenly remove surplus, need not be painstakingly parallel with hand, improved the part processing qualification rate greatly, greatly reduce labour intensity; Part need respectively be arranged the chamfering unanimity, does not need to distinguish; Each arranges part angle high conformity, do not have the inconsistent phenomenon of angle between each row, and the upper and lower dish of each position zero part can mix and puts the generation of preventing error.Therefore solved two-sided symmetrical low-angle (about 20 minutes), micro parts (less than 10mm) well and all be the difficult problem of appearance in the super-smooth surface processing.
