Description
Technical field
The invention belongs to optical instrument mounting technology field, relate generally to a kind of process unit that the optical axis of optical instrument is debug, especially design and a kind of many visual fields TV is seen the process unit that the collimation of the collimation take aim at the tool optical axis and optical axis and reference field is debug.
Background technology
The TV sight is taken aim at each optical axis of the large, medium and small visual field of tool requirement and is parallel to each other, and each visual field optical axis is parallel with reference field, in use requires optical axis to keep stablizing constant.Because the existence of part's machining errors and rigging error has caused between each visual field optical axis and the collimation error of optical axis and installation base surface, therefore need when debuging, carry out correction of a final proof.Debug in the process at product, usual way is that the mode that adopts the square tube preset lens to combine with parallel light tube is carried out adjustment, and reset error is big, alignment difficulties but this method is installed, and is difficult to satisfy the requirement of product to plain shaft parallelism and stable adjustment.
At present, Changchun Institute of Optics, Fine Mechanics and Physics, CAS's " detection method of the optical axis and the installation base surface depth of parallelism " patent (application number 03127024.7 that China announces, notification number CN1236278C), be to adopt the dull and stereotyped detection that realizes the optical axis and the installation base surface depth of parallelism of three adjustment platforms, two parallel light tubes, prism and.This method is earlier with three adjustment platforms and prism optical axis and the dull and stereotyped basal plane leveling row with two parallel light tubes; To be placed on the flat board by the system of debuging again, and one of them parallel light tube optical axis be transferred to and is overlapped by being debug systematic optical axis, measure the angle of two parallel light tube optical axis deviations at this moment, then finish the check of system optical axis and its installation base surface depth of parallelism.It is to utilize prism the optical axis of optical system and the measurement of the dull and stereotyped depth of parallelism to be converted to the measurement of two parallel light tube parallelisms of optical axis.But this method equipment needed thereby instrument more (two parallel light tubes and three platforms), it is complicated to set up instrument, and has the installation repetitive error.
Summary of the invention
The technical problem to be solved in the present invention is, at problems of the prior art, for many visual fields TV see the many plain shaft parallelisms take aim at tool and stability debug provide a kind of simple in structure, instrument sets up convenience, alignment precision height, the technique detection device that do not have an installation repetitive error is that optical axis is debug device.
For solving the problems of the technologies described above, optical axis of the present invention is debug device and is comprised adjustable platform, base plate, riser, catoptron, parallel light tube, electric cross generator and display, parallel light tube has eyepiece and bore can hold whole visual fields that tool is taken aim in the TV sight simultaneously, it is groove that described base plate front has the corresponding with it position of the strip bulge and the back side, and strip bulge is provided with one group of via hole in one line; The lower end of described riser has projection limit forward, right flank is a mirror body installed surface, plate body front surface outside the projection limit all has highly identical boss face for four jiaos, it is corresponding respectively to see the mounting hole of taking aim at the tool side with a mounting hole and position and TV on each boss face, have on the lower surface of riser and the corresponding one group of screw of described one group of via hole, the upper surface on projection limit is promptly mutually orthogonal by face, boss face and mirror body installed surface three; Described catoptron is bonded on the described mirror body installed surface and mirror mirror and describedly still keep quadrature by face and boss face; The back side of described base plate is placed on the adjustable platform, and the lower surface of riser is sitting on the described strip bulge and by screw and is connected; When debuging, being debug TV sees the reference field take aim at tool and is close to and describedly is connected by screw and described boss face by face and side, described parallel light tube be erected at debug TV see the dead ahead take aim at tool and with described catoptron autocollimation, described display and electric cross generator are all by cable and debug TV and see and take aim at tool and link to each other, the electric cross curve that electricity cross generator generates, the graduation cross curve of parallel light tube is presented at respectively on the described display after TV is seen the different view field imagings of taking aim at tool through debuging.
Beneficial effect of the present invention is embodied in the following aspects:
(1) adjustable platform among the present invention is formed by the used common scraping platform transformation of the way of pincers worker, only increases by three adjustment positions in the bottom and gets final product, and is therefore very simple and convenient.By the control hand wheel of rotation adjustable platform, utilize 3 levelling principle can realize that TV sees the trace adjustment of position angle when taking aim at tool and debuging.
(2) the present invention is mutually orthogonal with the face of leaning on and boss face at the bonding catoptron of riser right flank, and make catoptron vertical with the parallel light tube optical axis, realized that TV is seen and taken aim at debuging of each visual field plain shaft parallelism of tool and optical axis and installation base surface collimation and be converted to the TV sight and take aim at debuging of tool optical axis and parallel light tube plain shaft parallelism, thereby unified to debug benchmark preferably, avoided the benchmark transformed error.
(3) the present invention has changed the mode of aiming at cross curve with two parallel light tube intervisibilities with parallel light tube and catoptron autocollimation.Because the catoptron rotation can make emergent light axis with the twice angular turn, so the present invention can double the alignment precision of debuging benchmark.
(4) the present invention is in use debug TV and sees and to take aim at tool and install and settle at one go, needn't reinstall in optical axis adjustment and the environmental experiment process, and benchmark does not change, and has therefore avoided the installation reset error.
(5) the present invention only needs several common platform and general parallel light tubes from workpieces, a transformation of the way, electricity consumption cross generator and display are auxiliary to be observed, can realize the adjustment of product optical axis, have simple in structure, set up conveniently, little, characteristics such as operation link is few, adjusting accuracy height take up room.
