Description
Technical field
The present invention relates to self-locking device conventional in a kind of mechanical-optical setup, be specifically related to lock in mechanical-optical setup the higher occasion of required precision.
Background technique
In the follow-up light path of large telescope, often there is a series of indoor optical table that is positioned at, each piece eyeglass on these platforms or prober belong to the some of whole telescope light path equally, therefore harsher to its status requirement, must meet certain tolerance range, just can reach optical design requirement.
For optical lens, in the time debuging, often need the position of optical lens to adjust, optical lens is generally arranged in adjusting seat, and adjusting seat is arranged on the slide unit of a translation driving by nut screw mechanism or arc guide rail etc. or rotation, adjust the position of optical lens in light path by manual or electronic mode.After adjustment, need to lock the position of optical lens, avoid because of vibrations or other surprisingly cause the change of optical lens position.
For prober, often need to adjust the position of prober target surface in light path, the focusing of namely often saying.The most frequently used is arranged on prober on a transportable optical table exactly, after debuging, and platform locking movably, thus the position of fixed detector in light path.
Traditional lock mode is generally thread lock, by rotation screw thread, and fixing movable part.This lock mode is because the rotation of screw thread can bring the minor alteration of movable part displacement, and light is very responsive to this small change, causes the light path of debuging to be destroyed, and need to again debug.This lock mode has caused work to repeat, inefficiency.Therefore need a kind of locking framework that can not cause to position change in locking process.
Summary of the invention
The present invention solves the mode that adopts thread lock in existing mechanical-optical setup, there is the change of moving member displacement and cause the destruction to light path, and cause the problem that device utilization efficiency is low, a kind of highi degree of accuracy being applicable in mechanical-optical setup device that cuts off self-lock is provided.
Be applicable to highi degree of accuracy in the mechanical-optical setup device that cuts off self-lock, comprise electromagnetic chuck, Compress Spring, electromagnetic chuck seat, suction block, linear bearing, slide block, sliding axle, flange, friction plate and fixed base; Described electromagnetic chuck is fixed on slide block by electromagnetic chuck seat, linear bearing is connected on slide block, sliding axle is through linear bearing, realize sliding up and down of sliding axle, the two ends of sliding axle connect respectively suction block and flange, on described flange and fixed base, be bonded with respectively one deck friction plate, between described suction block and electromagnetic chuck, Compress Spring be set; Described Compress Spring is in pressured state; In the time of power-off, the pressure that Compress Spring produces orders about suction block and sliding axle moves downward, and the friction plate on friction plate and the fixed base on flange is compressed, and realizes locking; In the time switching on to electromagnetic chuck, electromagnetic chuck produces magnetic force, and the gap between this magneto drive suction block and electromagnetic chuck reduces, and the friction plate on flange is separated with the friction plate on fixed base, realizes release.
Beneficial effect of the present invention: the present invention adopts electromagnetic chuck time to have magnetic in energising, and do not have magnetic feature when power-off, develop a kind of highi degree of accuracy locking device that does not change original position.Debuging in process, locking device, in "on" position, does not affect optics and debugs.After having debug, power-off, the magnetic of electromagnetic chuck disappears, and under the pressure of Compress Spring, the friction plate on moving member is tightly pressed on fixed base, thereby has realized the high-precision locking of original position.Because this lock mode is for cutting off self-lock, therefore very easy to use.Locking precision of the present invention is high, simple in structure, is convenient to mechanical-optical setup.
Brief description of the drawings
Fig. 1 is the cut off self-lock structural drawing of device of the highi degree of accuracy being applicable in mechanical-optical setup of the present invention;
In figure: 1, electromagnetic chuck, 2, Compress Spring, 3, electromagnetic chuck seat, 4, suction block, 5, linear bearing, 6, slide block, 7, sliding axle, 8, flange, 9, friction plate, 10, fixed base.
