Abstract
The invention relates to a spatial pitching and azimuth two-dimensional micro-adjustment tool which comprises an adjustment screw, an external thread sleeve, an upper ball head sliding block and a lower ball head sliding block, wherein the external thread sleeve, the upper ball head sliding block and the lower ball head sliding block are all sleeved on the adjustment screw, the upper ball head sliding block is positioned at one end of the external thread sleeve, and the lower ball head sliding block is positioned at the other end of the external thread sleeve. In order to solve the technical problems that the existing method for determining the optical axis reference of the aspheric reflector causes reference change and the like, the invention utilizes the relative sliding of the ball head sliding block and the external thread sleeve to control the posture, does not generate local stress, does not generate deformation of the reference cross wire, and is convenient to disassemble.
Description
Technical field
The present invention relates to a kind of benchmark adjustment frock.
Background technology
Along with the widespread use of optics R-C system, the priority control link being determined to become the process of debuging of primary mirror, secondary mirror relative position, the optical axis of primary mirror and secondary mirror needs point-blank, so just ensures the imaging effect of high-quality.Common way first determines that primary mirror optical axis benchmark regulates secondary mirror optical axis and its unification again.The method of traditional determination aspheric surface reflector benchmark is the frock adopting one to be called " three tops three are drawn ", first this frock is connected on non-spherical reflector, then find the optical axis of non-spherical reflector, by top, the mode of screw is drawn to regulate the space position solution of crosshair graticule, until crosshair and optical axis coincidence.
The method shortcoming:
1, pass through top, draw the mode of screw to adjust graticule spatial attitude, frock local can produce larger stress, and along with passage of time stress slow releasing, continuation trace can occur differentiation plate spatial attitude changes, and namely benchmark will change by continuation trace;
2, this kind of frock is in course of adjustment and usually can not dismantles movement, interferes and understand noisy reflection mirror type to detect with other element, very inconvenient.
Summary of the invention
Existingly determining that the method for aspheric surface reflector benchmark causes the technical matters of benchmark change etc. to solve, the invention provides the pitching of a kind of space, orientation bidimensional trace adjustment frock and utilizing this frock to determine the system of optical element benchmark.
Technical solution of the present invention:
A kind of space pitching, orientation bidimensional trace adjustment frock, its special character is: comprise adjustment screw, external thread sleeve, upper bulb slide block and lower bulb slide block, described external thread sleeve, upper bulb slide block and lower bulb slide block are all sleeved on adjustment screw, described upper bulb slide block is positioned at one end of external thread sleeve, and described lower bulb slide block is positioned at the other end of external thread sleeve.
Determine the system of optical element benchmark, its special character is: comprise three adjustment frock, flange plate-like fixture, optical module stationary installation, internal focusing telescope, CCD camera and PCs, three adjustment frocks are uniformly distributed and are fixed on flange plate-like fixture, plane mirror is fixed on one end of optical module stationary installation, described internal focusing telescope one end is towards plane mirror, the other end is connected with PC by CCD camera
Described adjustment frock comprises adjustment screw, external thread sleeve, upper bulb slide block and lower bulb slide block, described external thread sleeve, upper bulb slide block and lower bulb slide block are all sleeved on adjustment screw, described upper bulb slide block is positioned at one end of external thread sleeve, and described lower bulb slide block is positioned at the other end of external thread sleeve; Described external thread sleeve is fixedly connected with flange plate-like fixture,
Described adjustment screw is fixed on the other end of optical module stationary installation, and described lower bulb slide block contacts with optical module stationary installation.
The advantage that the present invention has:
1, the present invention utilizes the relative sliding of bulb slide block and external thread sleeve to control attitude, and can not produce local stress, reference cross silk can not produce distortion, and convenient disassembly;
2, this reference cross silk not only can demarcate primary mirror optical reference, and can be used as the optical reference that primary and secondary mirror system debugs.
Accompanying drawing explanation
Fig. 1 is the structural representation of space pitching, orientation bidimensional trace adjustment frock;
Fig. 2 is the process schematic determining optical element benchmark;
Fig. 3 is the system schematic determining optical element benchmark;
Wherein Reference numeral is: the upper bulb slide block of 1-, 2-external thread sleeve, and bulb slide block under 3-, 4-adjusts screw
Embodiment
The structural representation of trace adjustment frock as shown in Figure 1, forms space pitching, orientation bidimensional trace adjustment frock by upper bulb slide block 1, external thread sleeve 2, lower bulb slide block 3 and adjustment screw 4.External thread sleeve, upper bulb slide block and lower bulb slide block are all sleeved on adjustment screw, and upper bulb slide block is positioned at one end of external thread sleeve, and lower bulb slide block is positioned at the other end of external thread sleeve.3 cover frocks on fixation kit 120 ° uniform be arranged on flange plate-like fixation kit and optical element supporting component with the use of, optical element can be realized and adjust at the trace of space two dimension.
As Fig. 2, the system of optical element benchmark is determined shown in 3, comprise three adjustment frocks, flange plate-like fixture 5, optical module stationary installation 6, internal focusing telescope 7, CCD camera 8 and PC 9, three adjustment frocks are uniformly distributed and are fixed on flange plate-like fixture 5, plane mirror 10 is fixed on one end of optical module stationary installation, internal focusing telescope one end is towards plane mirror, the other end is connected with PC by CCD camera, adjustment frock comprises adjustment screw, external thread sleeve, upper bulb slide block and lower bulb slide block, external thread sleeve, upper bulb slide block and lower bulb slide block are all sleeved on adjustment screw, described upper bulb slide block is positioned at one end of external thread sleeve, lower bulb slide block is positioned at the other end of external thread sleeve, external thread sleeve is fixedly connected with flange plate-like fixture, and adjustment screw is fixed on the other end of optical module stationary installation, and lower bulb slide block contacts with optical module stationary installation.
Concrete steps:
1,3 cover trace adjustment frocks, 120 ° of uniform threaded engagement on flange plate-like fixation kit are installed;
2, optical element supporting component is connected on flange plate-like fixation kit by 3 place's adjustment screws;
3, now by monitoring the reflection image of internal focusing telescope on optical element surface, what adjust different screw shell and adjustment screw is threaded into degree, ensures the pitching of optical element in space and orientation attitude.
If the parallel beam that a internal focusing telescope sends is after optical element surface reflection, converge to internal focusing telescope graticule center, then the beam orthogonal of optical element surface and internal focusing telescope is described;
If the parallel beam that b internal focusing telescope sends is after optical element surface reflection, converge to other position of internal focusing telescope graticule, then illustrate that there is angle on optical element surface with the light beam of internal focusing telescope;
4, after adjusting to request for utilization position, must ensure that 3 adjustment screws all keep tightening state.
