Detailed description of the invention
For technique scheme, now lift a preferred embodiment and be specifically described in conjunction with diagram.Referring to Fig. 1 to Fig. 2, the precision surface plate mechanism that the XYZ free degree of the present invention is adjustable, mainly comprises platform floor, fine adjustment stage, screw mandrel, line slide rail, wherein.
Platform floor 1 is level board.On close two Angle Position of the same side on platform floor, be arranged with base plate line slide rail 2 respectively in parallel, base plate line slide rail 2 is provided with slide block 21, slide block 21 is provided with line slide rail 22, the direction of line slide rail 22 and the direction of base plate line slide rail perpendicular.Line slide rail 22 is provided with slide block 23, slide block 23 is provided with platform seat, platform seat is provided with bearing 24.Platform floor between two base plate line slide rails is arranged with two screw mandrels 3 in parallel, screw mandrel 3 one end is connected with stepper motor 31 by screw mandrel shaft coupling, and screw mandrel 3 other end is free end.Stepper motor can drive screw mandrel to rotate.Screw mandrel 3 is arranged with movable block 32, and movable block 32 is fixedly connected with the slide block 21 on the base plate line slide rail of its side.When stepper motor rotating band movable wire bar rotates, then movable block does straight-line displacement under the effect of screw mandrel, thus band movable slider 21 does straight-line displacement along base plate linear slider; When applying the external force perpendicular to base plate line slide rail direction to bearing, bearing can under the drive of slide block 23 linearly slide rail 22 do straight-line displacement.Therefore, each bearing can realize straight-line displacement all around.
On close two Angle Position of the opposite side on platform floor, be arranged with base plate line slide rail 4 respectively in parallel, base plate line slide rail 4 is provided with slide block 41, slide block 41 is provided with line slide rail 42, the direction of line slide rail 42 and the direction of base plate line slide rail perpendicular.Line slide rail 42 is provided with slide block 43, slide block 43 is provided with platform seat, platform seat is provided with bearing 44.Slide block 41 along base plate line slide rail 4 straight-line displacement direction and slide block 21 perpendicular along base plate line slide rail 2 straight-line displacement direction.The platform floor of base plate line slide rail 4 side is wherein provided with screw mandrel 5, and screw mandrel 5 one end is connected with stepper motor 51 by screw mandrel shaft coupling, and screw mandrel 5 other end is free end.Stepper motor can drive screw mandrel to rotate.Screw mandrel 5 is arranged with movable block 52, and movable block 52 is fixedly connected with the slide block 41 on the base plate line slide rail of its side.When stepper motor rotating band movable wire bar rotates, then movable block does straight-line displacement under the effect of screw mandrel, thus band movable slider 41 does straight-line displacement along base plate linear slider; When applying the external force perpendicular to base plate line slide rail direction to bearing, bearing can under the drive of slide block 43 linearly slide rail 42 do straight-line displacement.Therefore, each bearing can realize straight-line displacement all around.
The platform floor side being positioned at each base plate line slide rail and its top shoe side is all arranged at intervals with two photoelectric sensors 6, and photoelectric sensor 6 lays respectively at the side, two ends of base plate line slide rail, is provided with optoelectronic induction sheet 61 between photoelectric sensor.One end of optoelectronic induction sheet is fixedly connected on the slide block on base plate line slide rail; Its other end is free end, between photoelectric sensor 6.By the effect of optoelectronic induction sheet and photoelectric sensor, slide block can be controlled in base plate line slide rail top offset distance.
Fine adjustment stage 7, is positioned at the top of platform floor, stepper motor and line slide rail.Corresponding position of bearings place offers installing hole thereon, and bearing 24 and bearing 44 lay respectively in installing hole.Platform seat carries out horizontal support to fine adjustment stage, and bearing supports fine adjustment stage and position limits, and drives fine adjustment stage displacement all around and around Z axis vernier angle.
Operation principle of the present invention: first suppose that stepper motor 31 drives fine adjustment stage to move to X-axis positive direction clockwise, stepper motor 51 rotates clockwise and drives fine adjustment stage to move to Y-axis positive direction.When two stepper motors 31 rotate clockwise simultaneously, drive screw mandrel rotates clockwise, then slide block 21 does rectilinear motion along base plate line slide rail to X-axis positive direction under the drive of movable block, and the bearing 44 of the other side of platform floor also does straight-line displacement in the same way along line slide rail 42 under driving.Because bearing is installed in fine adjustment stage, then drive fine adjustment stage to the displacement of X-axis positive direction; When two stepper motors 31 rotate counterclockwise simultaneously, then fine adjustment stage is driven to do straight-line displacement to X-axis negative direction.Screw mandrel 5 is driven to rotate clockwise when stepper motor 51 rotates clockwise, then do straight-line displacement with sheathed movable block band movable slider on screw mandrel 5 along base plate line slide rail, the bearing 24 being positioned at platform floor opposite side also under this driving force linearly slide rail 22 do straight-line displacement in the same way.Because bearing is installed in fine adjustment stage, therefore, drive fine adjustment stage to the straight-line displacement of Y-axis positive direction.By stepper motor 31, stepper motor 51 and drive screw mandrel, movable block etc. motion combine, the position adjustments of fine adjustment stage in XY direction of principal axis can be realized.When two stepper motors 31 1 rotate clockwise, one when rotating counterclockwise, because the bearing in fine adjustment stage can rotate, therefore, fine adjustment stage can be driven to rotate certain angle around Z axis, this angle adjustment scope control is within ± 5 ° of scopes.
By the adjustable fine adjustment stage of the XYZ free degree of the present invention, fine adjustment stage can be realized and regulate at the axial horizontal level of XY, and around the angular adjustment of Z axis.Fine adjustment stage of the present invention, simple and compact for structure, the space occupied is little, and is convenient to regulate.The fine adjustment of fine adjustment stage can be realized by the displacement of the rotating speed of Automated condtrol stepper motor and movable block.
