The utility model can be used for all four dimensional regulating purposes which need to carry out high-precision pitching rotation, right and left rotation, horizontal slide, vertical slide, etc.
Description
The utility model belongs to multidimensional precision optical machinery amount displacement adjustment technology device.
Multidimensional mechanical shift amount adjusting apparatus is widely used parts in science and technology and production practices, for example, the various catoptron adjustment racks that use in optical instrument such as laser instrument and the experiment, the precision positioning adjustment rack of the range detector spare that uses in the electronic device
Fig. 1 and Fig. 2 are the four-dimensional adjustment rack assembling schematic diagrams of widely used a kind of multilayer plate in the prior art.Wherein Fig. 1 is a front elevation, and Fig. 2 is a left view.
The piece mark of Fig. 1 and Fig. 2 is: base (1), fixedly deckle board (2) rotates deckle board (3), cross sliding clock (4), dovetail vertical slipper (5), pitch rotation release handle (6), left-right rotation release handle (7), horizontal slip release handle (8), vertical slidable adjustment handle (9), steel ball (10), steel wire extension spring (11) and (12), the extension spring bar (13) of stumbling, (14), (15) and (16), jump ring (17), level top spring (18) and (19), vertical top spring (20) and (21), outer collar (22), interior collar (23).
Illustrate below in conjunction with Fig. 1 and Fig. 2 how " plate to " relative motion in the Mnltilayered structures realizes regulating.
With base (1) and fixedly deckle board (2) adjust object of reference.
To support steel ball (10) be fulcrum, and rotation deckle board (3) is with respect to fixing deckle board (2) pitching and left-right rotation up and down.Pitch rotation release handle label is (6), and left-right rotation release handle label is (7).There is not the gap of rocking for making reciprocal rotation, jump ring (17) directly blocks fixedly deckle board (2) and rotation deckle board (3) at steel ball (10) adjacency, in addition also by two steel wire extension springs (30) and (31) and four extension springs bar (13) of stumbling, (14), (15), (16) hold fixedly deckle board (2) and rotation deckle board (3) respectively.
Rotate horizontal slip release handle (8), can realize that cross sliding clock (4) reciprocatingly slides with respect to the level of rotating deckle board (3).The gap that two level top springs (18) and (19) are used for eliminating reciprocal adjusting.
Rotate vertical slidable adjustment handle (9), can realize that vertical slipper (5) slides with respect to the back and forth vertical of cross sliding clock (4).The gap that two vertical top springs (20) and (21) are used for eliminating reciprocal adjusting.
Outer collar (22) one ends have internal thread, and the other end has external thread, and there is a boss at the middle part.The boss plane of outer collar is that planar slide cooperates with rotating deckle board (3).The screw-internal thread fit at the male end of outer collar (22) and vertical blocks (5) middle part.
External thread on the interior collar (23) is from the opposite direction of outer collar, with the screw-internal thread fit of vertical slipper (5).Since inside and outside two collars respectively from the both direction screw fixed on the internal thread at vertical slipper (5) middle part, make the boss plane of outer collar (22) and rotate between the outerplanar of deckle board (3) suitable glade plane space is arranged, and be carrier to rotate deckle board (3), carried cross sliding clock (4) and vertical slipper (5), brought in connection by the internal thread of outer collar (22) and be adjusted thing.
The Principles of Regulation of above-mentioned sandwich construction are: with base (1) with fixedly deckle board (2) is motionless as adjusting object of reference.Rotate deckle board (3) with respect to the pitching and turn right and move up and down of fixing deckle board (2).Cross sliding clock (4) slides with respect to rotating deckle board (3) horizontal direction.Vertical slipper (5) slides with respect to the horizontal vertical direction.Outer collar (22) is fixed on the vertical slipper (5), is adjusted thing and is fixed on the outer collar (22).
The major defect of above-mentioned multilayer board block structure is:
1) for reaching adjustment amount, between the plate that relatively moves the principle geometric gap must be arranged, and geometric gap causes reciprocal adjusting unstable and unreliable.The more important thing is the high precision adjusting that should not realize micron～submicron order.
2) when carrying out two angular adjustment, center of rotation thereby brings unwanted translational movement skew angular adjustment the time again not on the central axis of adjustment rack.
3) adjustable dimension is many, and the plate logarithm that relatively moves is many, requires the machining accuracy height, and the assembly precision height is difficult for producing the cost height in batches.
The purpose of this utility model is:
1) eliminates the principle geometric gap that the multilayer board block structure relatively moves and causes, thereby can realize the adjusting of submicron order high precision.
The translational movement of following that causes when 2) eliminating angular adjustment is offset.
3) eliminating the multilayer board block structure, is that main body reaches four-dimensional adjusting with one whole, and the machining of being more convenient for and production assembling reduce cost.
