Description
Technical field
The present invention relates to a kind of precision optical machinery parts, particularly relate to a kind of fine setting travelling carriage that is used for devices such as photoelectricity precision optical machinery instrument, instrument.
Background technology
Up to now, in precision optical machinery motion design and the manufacturing, the mechanical movement precision, the one, by the raising machining accuracy, the 2nd, guarantee by advanced Rational structure.Comparatively common precision optical machinery moving component is made up of accurate worm drive pair, spring, tapering spring cover, attic base etc.This is theoretic structure, and stage clip is contained in the tapering spring cover, and the stage clip external diameter contact with tapering spring cover internal diameter and the axial force of stage clip and tapering spring overlap with one heart, and in fact this does not accomplish.Actual structure is that stage clip is contained in the tapering spring cover, and the stage clip external diameter contacts with a side of tapering spring cover.During work, turn accurate screw pair, tapering push rod, push rod is just oppressed tapering spring cover and is moved forward and backward.Because the interior edge of tapering spring cover always contacts with stage clip one side, stage clip and tapering spring cover are bound to produce uneven frictional force, can also hear the grating of chuckleing sometimes.So just caused in this parts use the inhomogeneities of elastic force and beating of motion to occur, in addition the structure more complicated.
Also have a kind of structure to form, control running clearance to eliminate idle running error with the split gear that adds spring by gear, tooth bar, axle etc.Also have a kind of structure to form, eliminate worm gear, worm engaging central backhaul error with the sheet spring by worm gear, worm screw, axle, axle bed, sheet spring, stage clip etc.Described these two kinds of structures are all too complicated, and cost is too high.
Summary of the invention
The objective of the invention is to: overcome the shortcoming of above-mentioned prior art, in use regulate even, soft the stablizing that seesaw in order to reach the fine setting travelling carriage; And eliminate the hysterisis error that the micrometer bar seesaws, reach the raising trimming precision, thereby a kind of compact conformation, the fine setting travelling carriage that is used for the precision optical machinery device that cost is low are provided.
The object of the present invention is achieved like this:
The invention provides a kind of fine setting travelling carriage that is used for the precision optical machinery device, comprising: one is
The dovetail slide bearing groove that has in the base of shape, base bilateral wall has dovetail slide bearing groove depth difference in the two side, wherein dark guide rail cell wall external-open has through hole, and jackscrew is housed in the through hole; The two ends, bottom surface of base respectively have a groove, are equipped with in it and also have a plurality of screw holes on bottom surface of loading magnetic material, base in magnetic support and the magnetic support, and a step counter sink arranged at the groove back side; One slide plate, slide plate are provided with two one slide rails of joining with base rail groove cunning, and there is a partition at two one slide rail centers on slide plate, and the either side of partition has a stepped hole, and magnetic material is housed in the hole; The two one slide rails outside has a groove, and the bottom of each groove has a slit, and bead-distributing plate is housed in the slit, has a plurality of steel balls hole on the bead-distributing plate, in its hole steel ball is housed; Slide plate is joined installation by dovetail groove cunning on slide rail and the base, steel ball coincide in the middle of slide plate and base, regulate bar and be filled between slide plate slide rail and the base rail groove, form the fine setting mobile station body, between the adjusting bar at the two-port place that finely tunes mobile station body and slide rail, axle is housed; One
The screw bolt seat of shape, the top of screw bolt seat has a hole, fixes a micrometer bar in the hole, and the bottom of screw bolt seat has screw, the position that this screw is opened is relative with the screw that the bottom surface of base one side is opened, and screw bolt seat and base fix by the above screw of two parts; The front end of slide plate has a center hole, and the micrometer bar crown of passing in the screw bolt seat hole is on center hole.The magnet of being fixed on base and the slide plate is oppositely arranged with heteropole, so the magnetic force of a direction is arranged; Because screw bolt seat is fixed on an end of base, and a screw rod is arranged again on the screw bolt seat, when turning screw rod, screw rod promotes slide plate to the opposite direction motion of magnetic force, and slide plate moves in axle upper edge magnetic force direction through steel ball; Three blocks of magnetic materials when mounted its pole orientation by the installation direction of deciding magnetic material with the gap of eliminating the guide rail movement direction.
Three sides and the bottom surface that also are included in slide plate all have a plurality of screws, can respectively or simultaneously a fine setting travelling carriage or a plurality of fine setting travelling carriage be combined by the screw on three sides and the bottom surface, are formed on multidirectional fine setting travelling carriage.
Also comprise a stepper motor and computer, the axle of a stepper motor connects by elasticity connecting axle and micrometer bar, and computer is electrically connected with stepper motor.
Described micrometer bar is a no gap screw rod, and the top of its screw rod is cup head, and the screw rod of cup head withstands on the center hole of slide plate; Or a micrometer micrometer bar, its top is tack, just needs to place a globule, micrometer bar tack top to withstand on the globule in the slide plate center hole in the center hole of nose.
The slit that described slide rail outer concave trench bottom is opened is one half elliptic, and this slit leaves one section (promptly do not open mouthful) on the groove both sides.
One side of described bead-distributing plate is the ellipse that a slit of opening with slide rail outer concave trench bottom matches, and three limits are the half elliptic (as shown in Figure 6) of straight flange in addition, have a plurality of holes along the bead-distributing plate straight flange, and steel ball is placed in the hole.
Described magnetic material is a ndfeb magnet.
The invention has the advantages that: (1) fine setting travelling carriage that is used for precision optical machinery provided by the invention overcomes existing technology and regulates platform backhaul gap error, in use usually occurs beating or the uneven shortcoming of elastic force; Since be provided with magnetic material, the principle of utilizing the magnetic material heteropole to inhale mutually, as flexible member, flexible member does not directly contact with movement parts with magnetic force, and its active force is even, soft, stable, and can reach the assembling trimming precision is more than the 0.005mm.
(2) fine setting travelling carriage of the present invention is simple in structure, compact, cost is low.
(3) fine setting travelling carriage of the present invention can be organized combination more, realizes multidirectional fine setting; This fine setting travelling carriage applicability is strong, can be widely used in precision optical machinery and the photoelectricity precision instrumentation.
The present invention is described in detail below in conjunction with accompanying drawing and embodiment:
