Description
Technical field
The present invention relates to optical device translation stage, especially relate to guide rail latch assembly.
Background technology
Translation stage, as a basic module of contemporary optics instrument, for adjusting optical element, is realized beam direction and is located fast and accurately, in laboratory and optical device, is widely used.In optics industry, the positional accuracy of translation stage is had relatively high expectations, after adjustment, need to fix its working position by guide rail locking apparatus, prevent that vibrations and unexpected touching from causing working position that unexpected variation occurs.Existing guide rail locking apparatus adopts locking adjust knob or connect dynamic and static two parts part and realize position and fix with locking steel disc and screw more.The fixing stability of the poor very easily impact position of connection rigidity of this locking device, the mode that simultaneously adopts locking to adjust knob can not be eliminated and adjust the position uncertainty that screw clearance may bring.
Summary of the invention
The object of this invention is to provide guide rail latch assembly, overcome the deficiency of above-mentioned existing track locking device, have advantages of that locking effect is good, stability is strong, operating performance is good.
Object of the present invention is achieved through the following technical solutions: guide rail latch assembly, comprise locking clamp, left-hand threaded nut and tie down screw, described locking clamp comprises the locking plate that two left and right are oppositely arranged and connects the base of two locking plates, right side locking plate is provided with right-hand thread hole, left side locking plate is provided with through hole, described left-hand threaded nut is fixedly connected on left side locking plate, the left end of described tie down screw is provided with the left-hand thread (LHT) adapting with left-hand threaded nut, tie down screw is provided with the right-hand thread adapting with right-hand thread hole, described right-hand thread is positioned at the right side of left-hand thread (LHT), the left end of tie down screw is through through hole, by left-hand thread (LHT), coordinate with left-hand threaded nut, by right-hand thread, coordinate with right-hand thread hole.Thereby the present invention firmly clamps guide rail by the opening of the collapsible locking clamp of rotational lock screw rod and realizes the fixing of translation stage position.
Further, the diameter of described through hole is greater than the diameter in right-hand thread hole.So, thus the right-hand member of being convenient to tie down screw cooperatively interacts right-hand thread and right-hand thread hole through through hole.
For guaranteeing that the left-hand thread (LHT) of tie down screw can cooperatively interact with left-hand threaded nut, further, described left-hand threaded nut is fixed by attachment screw and left side locking plate, and the threaded hole in left-hand threaded nut and described through hole coaxially arrange, and the diameter of threaded hole is less than through-hole diameter.
Further, the right-hand member of described tie down screw is provided with six square toes.So, can be convenient to realize by spanner rotational lock screw rod the increase and decrease of locking clamp opening size.
For improving the stability of position between locking clamp and guide rail, be convenient to locking operation, further, described base is provided with retaining thread hole.So, thus can avoid when rotational lock screw rod occurrence positions skew between locking clamp and guide rail to be beneficial to the adjusting to locking clamp opening.
For ease of shrinking locking clamp opening, further, the junction of described two locking plates and described base is provided with transversely deforming groove.So, when rotational lock screw rod, two locking plates are beneficial to displacement in opposite directions occur.
Compare with existing mounting structure, the present invention has following beneficial effect: thus the present invention realizes the fixing of translation stage position by the opening size of the collapsible locking clamp of rotational lock screw rod firmly to clamp guide rail, not only locking effect is good, stability is strong, and compact conformation, simple to operate.In addition, during this invention work, can avoid guide rail and run between the object of guide rail top producing larger friction force, thereby be conducive to protect the rubbing surface of guide rail.
