Abstract
The invention relates to an optical height adjusting device which comprises a dock, the lower end of which can be mounted on any plane, a rod-like component arranged in the dock, a screw mechanism mounted in the dock, and a compression spring. When rotating the screw mechanism to produce a small displacement for the rod-like component, the compression spring produces a thrust acting force for the rod-like component, making the rod-like component contact the screw mechanism without gaps, thus maintaining accuracy of the height adjusting device.
Description
Technical field
The present invention relates to a kind of height adjuster, particularly a kind of optics height adjuster.Optics height adjuster disclosed by the invention is for carrying out Experiments of Optics or being applied to all suit on the optical instrument.This height adjuster also can be used for other field, such as amount side, machining, product assembling etc.If arrange in pairs or groups motor and electrical control mechanism again, become electronic fine setting height devices, also quite suitable for the robotization industry.
Background technology
When carrying out Experiments of Optics, need to use anchor clamps with the clamping optical module, do light or other purposes, carry out the light time, need to use the device of adjusting height, so that carry out accurate in locating and contraposition.
General optical element, as eyeglass etc., usually with the microscope base clamping, and utilize support stick and supporting seat to be fixed on the optics table, support stick is fixed can adjust required height in supporting seat after, but can only adjust roughly, very accurately adjusts highly if need, must arrange in pairs or groups again the height mobile platform, be commonly referred to as Z axle translation stage (Z stage).
Existing height adjuster, as shown in Figure 1,101 is support bar, and 102 is supporting seat, and 103 is knob, and 104 is mobile platform.Optical module such as lens etc., be installed on the support bar 101, this support bar 101 is positioned on this supporting seat 102, and support bar 101 is moved up and down to carry out contraposition with manual stretching mode, use rotary knob 103 fixed support bars 101 after the contraposition, but this device can only carry out coarse adjustment, must cooperate high-precision mobile platform 104 again, can reach on the optics high-precision demand, but these high precision mobile platform 104 complex structures, cost an arm and a leg, take up space, install also time-consuming, support bar 101 easily gets loose in addition, causes work efficiency to reduce.
Summary of the invention
The objective of the invention is to design a kind of optics height adjuster, consider space and installation question in advance, with the device that support bar, supporting seat, mobile platform are combined as a whole, not only space saving, simple structure, manufacturing and assembling are easy, cost is also cheap.
Optics height adjuster disclosed by the invention mainly comprises a pedestal, and the lower end can be fixed on arbitrary plane, one rod component, place in the above-mentioned pedestal, axially easy on and off moves, a screw mechanism, be fixed in this pedestal, one end of this screw mechanism is a spiral cylinder, can axially move up and down, and become point to contact with above-mentioned rod component bottom, one compression spring is arranged at the bottom of this rod component.When this screw mechanism of rotation makes this rod component produce minute movement, compress between the clasp that this compression spring is provided with bottom rod component and the outshot of base interior, push back acting force to produce one, make and keep in touch between this rod component and this screw mechanism and do not have the gap and produce, to guarantee precision.
Optical module can be fixed in the upper end of this rod component, the bottom of this rod component contacts with the most advanced and sophisticated one-tenth point of the spiral cylinder of this screw mechanism, rotate this screw mechanism, can make the telescopic moving up and down of this spiral cylinder, but the body of this screw mechanism does not move, because of the bottom of this compression spring device in this rod component, the spring body is around this rod component, extend axially along this rod component, and the other end contacts with a teat of this pedestal inner face, so when this spiral cylinder moves up, promote this rod component and axially up move, compress the space at this compression spring place, make this spring produce a reverse thrust, this rod component and this spiral cylinder are kept in touch, to keep the precision of this height adjuster.
This rod component can select directly to be socketed on the inner face of this pedestal, perhaps use a lining, place in this pedestal, the outside surface of this lining contacts with the inside surface of this pedestal, this rod component then is socketed in this lining, the top device one location fastener of this pedestal is fixed in this lining in this pedestal, and this location fastener also can prevent this rod component rotation.
For preventing this rod component left rotation and right rotation, also can on this pedestal, install a fixed knob, and cut out a plane grooving vertically in the surface of this rod component, and adjust the depth of engagement between this fixed knob and this rod component plane grooving, can prevent this rod component rotation and slide vertically.
This screw mechanism can be directly fixed on this pedestal, or use a ring set, an and bolt, this ring set is installed in this pedestal, the neck of collar inwall and this thread mechanism is with threaded engagement, utilize this bolt that this ring set is fixed on this pedestal, and then this screw mechanism is fixed on this pedestal.
There is an extended element this pedestal below, can significantly be adjusted to required height and fixing.This extended element can be fixed on the optics table easily.
Height adjuster of the present invention can be carried out the adjustment of height independently and not influence other degree of freedom, and has the function of coarse adjustment and fine setting simultaneously.
This device in conjunction with existing optics with support bar, supporting seat and high-accuracy mobile platform in the height adjuster in one, its advantage is that component part is few, simple structure, do not take up space, make that (assembling) cost is low, installations is easy, easy to operate, adjust precision good, be difficult for getting loose, load is big, can independently and stablize adjustment and do not influence other degree of freedom.So being to save cost and providing, fundamental purpose of the present invention uses operation more easily, to promote work efficiency.
For this above-mentioned purpose, feature and advantage can be become apparent, preferred embodiment cited below particularly and conjunction with figs. elaborate.
