The technical matters that the utility model solves can realize by the following technical solutions: a kind of optics micro actuator, comprise holder, adjustment plate, horizontal direction adjustment screw and vertical direction adjustment screw, described adjustment plate is connected with holder elasticity, adjustment plate and holder are provided with some circular holes, extension spring is provided with in described circular hole, described horizontal direction adjustment screw and vertical direction adjustment screw are all arranged on holder, between adjustment plate, holder and adjustment plate are respectively equipped with some threaded holes one, threaded hole two, horizontal direction adjustment screw and vertical direction adjustment screw respectively with threaded hole one, threaded hole two connects, described horizontal direction adjusts screw and vertical direction adjustment screw and holder junction and is all provided with lock pad, described holder is all provided with hole groove in the horizontal and vertical directions with adjustment plate, centering ball is provided with in the groove of hole, centering ball sphere is respectively with holder with adjust plate and be connected, described adjustment screw is provided with coaxial two helicitic texture.
Preferably, two helicitic textures that described horizontal direction adjustment screw and vertical direction adjustment screw are provided with are M4 and M5 standard thread.
Preferably, described threaded hole one is M4 internal and external threads hole, and threaded hole two is M5 internal and external threads hole.
Preferably, described M4 standard pitch is 0.7mm, M5 standard pitch is 0.8mm.
Preferably, described extension spring comprises spring body and dop, and dop is arranged on spring body two ends.
Employing the utility model has the advantage of: by the coaxial two threaded adjustment screw be provided with, and the acting in conjunction of the parts such as extension spring, centering ball and lock pad, the precision achieving this optics micro actuator adds more than 3 times, and employ the screw thread of standard, the effect of such adjustment is just better, the production of this optics micro actuator is also more efficient, reduces production cost.In a word, the invention of this optics micro actuator, for optical detecting instrument industry provides an outstanding roll-setting gear, and the utility model structure is simple, and be easy to operation, reliability is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is adjustment bolt structure schematic diagram of the present utility model.
Wherein: 1-horizontal direction adjustment screw, 2--extension spring, 3-adjustment plate, 4-centering ball, 5-lock pad, 6-vertical direction adjustment screw, 7-holder, 8-threaded hole two, 9-threaded hole one, 10-M4 standard thread, 11-M5 standard thread, 12-dop.
Embodiment
Principle of work of the present utility model is: described holder 7 is as the support of whole mechanism, be arranged on equipment, the acting in conjunction of screw 6 and extension spring 2 is adjusted by horizontal direction adjustment screw 1, vertical direction, adjustment plate 3 elasticity is connected on holder 7, rotate horizontal direction adjustment screw 1, vertical direction adjustment screw 6 will make adjustment plate 3 fine rotation in the horizontal direction or in vertical direction, and optical mirror slip is just arranged on adjustment plate 3, thus realize the object of light path adjustment.
Preferred implementation of the present utility model is described in detail below in conjunction with accompanying drawing.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of optics micro actuator, comprise holder 7, adjustment plate 3, horizontal direction adjustment screw 1 and vertical direction adjustment screw 6, described adjustment plate 3 is connected with holder 7 elasticity, adjustment plate 3 and holder 7 are provided with some circular holes, extension spring 2 is provided with in described circular hole, described horizontal direction adjustment screw 1 and vertical direction adjustment screw 6 are all arranged on holder 7, between adjustment plate 3, holder 7 and adjustment plate 3 are respectively equipped with some threaded holes 1, threaded hole 28, horizontal direction adjustment screw 1 and vertical direction adjustment screw 6 respectively with threaded hole 1, threaded hole 28 connects, described horizontal direction adjustment screw 1 and vertical direction adjustment screw 6 are all provided with lock pad 5 with holder 7 junction, described holder 7 is all provided with hole groove in the horizontal and vertical directions with adjustment plate 3, centering ball 4 is provided with in the groove of hole, centering ball 4 sphere is respectively with holder 7 with adjust plate 3 and be connected, described adjustment screw is provided with coaxial two helicitic texture, two helicitic textures that described horizontal direction adjustment screw 1 and vertical direction adjustment screw 6 are provided with are M4 standard thread 10 and M5 standard thread 11, described threaded hole 1 is M4 internal and external threads hole, threaded hole 28 is M5 internal and external threads hole, described M4 standard pitch is 0.7mm, M5 standard pitch is 0.8mm, described extension spring 2 comprises spring body and dop 12, dop 12 is arranged on spring body two ends.
The core of this optics micro actuator is that in the pitch of horizontal direction adjustment screw 1, vertical direction adjustment screw 6, just, precision is higher in pitch less adjustment Vietnamese side.The adjustment screw of micro actuator generally adopts the nonstandard screw thread of M4, M5, M6 in the market, and pitch is at 0.3mm.If it is difficult all the more to think that pitch reduces manufacture further.The utility model changes the structure of horizontal direction adjustment screw 1, vertical direction adjustment screw 6, adopts coaxial two helicitic texture, the i.e. STRTHD of M4 and M5.Beat the threaded hole of M4 and M5 at holder 7 and the correspondence position of adjustment plate 3 simultaneously.After installation, rotate adjustment screw, due to M4 standard pitch, to be 0.7mm, M5 standard pitch be that 0.8mm adjusts that screw revolves the Adjustment effect produced that turns around is exactly that the accurate screw thread of 0.8-0.7=0.1mm is not only processed simply, and precision is 3 times of existing product.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
