Summary of the invention
The purpose of this utility model is to provide a kind of positioner mechanism, to solve the problem that in existing positioner design, the location is low, driving error is too high.
Scheme of the present utility model is by such realization: construct a kind of positioner mechanism, comprise frame, motor and workbench, described frame is provided with switching mechanism and slew gear, described switching mechanism comprises trip shaft servomotor and flip piece, described flip piece middle part is provided with rotatable revolving part, in described revolving part with bolt hole; Described flip piece two ends are rotatably connected on frame, and described flip piece end is connected with the trip shaft servomotor; Described slew gear comprises workbench, pivoting support bearing and gyroaxis servomotor, described gyroaxis servomotor is connected with bolt hole in revolving part by bolt, and pivoting support bearing is fixedly connected with the revolving part top, and workbench is connected with pivoting support bearing.Operation principle of the present utility model is: by a flip piece is set, and rotatable bolt hole is set in flip piece, thereby makes modified gear can realize the upset of up and down and front and back, and the rotation rank is low, the rotating mechanism of employing is simple, and is easy to maintenance.It is high that more existing gear drive has accuracy, the advantage that stability is strong.
In the utility model, as further improvement, described trip shaft servomotor and gyroaxis servomotor are connected with respectively flip piece decelerator and gyroaxis decelerator.By to increasing decelerator on two servomotors, thereby make servomotor rotate to stop the time driving flip piece or bolt hole, can stop rapidly, avoid inertia to drive workpiece and continue rotation.
In the utility model, as further improvement, described flip piece decelerator lower position is provided with gripper shoe, and the effect of gripper shoe is to alleviate upset servomotor and flip piece decelerator to the moment of frame side, prevents the distortion of frame.
In the utility model, as further improvement, also be provided with direction limiting device on described frame, load onto that stopping means can guarantee in the situation that the soft spacing inefficacy of programme-control, hard spacing the playing a role of machinery, guarantee that workbench turns round within the working range of appointment, improved the reliability of mechanism.
In the utility model, as further improvement, described revolving part top also is provided with several flange shaft, described pivoting support bearing is connected with the flange shaft coupling by flange shaft sleeve, described flip piece top also is provided with brush, described brush contacts with pivoting support bearing, and brush can guarantee the smooth rotation of pivoting support bearing.
In the utility model, as further improvement, described flip piece top also is provided with the axle pad plate, makes between flip piece and pivoting support bearing directly not contact.
The utlity model has following beneficial effect:
1, the utility model has the advantages that and only used a transmission to two-stage, driving-chain is short, adopts the Combination Design of servomotor and planetary reduction gear, and precision is high, and stability is strong.
2, the utility model is simple in structure, and positioning accuracy has had greatly with respect to the gear drive positioner of transmission and improves, and is simple in structure, safeguards easy and conveniently, coordinates the control software commonly used or PLC system, can realize deflection function.
3, the utility model production cost is low, to make experimental prototype, is convenient to production firm and promotes the use at present.
