Background technology
It need a projector add an article showing platform existing projector for real object, and article showing platform is mainly used to show the picture of some entities, material object, negative film, the projection in the geometry such as positive.Its shortcoming is to see the view of three directions simultaneously, cannot build point, line, surface model and can occupy fixed space, cannot arbitrarily move.
On market, another kind of its purposes of product spatial digitizer is to create object geometric jacquard patterning unit surface.But price is more expensive, the collection of information is limited in certain scope and is not too applicable to classroom and uses.
Summary of the invention
The object of the present invention is to provide a kind of projector that can show many views of putting model.
To achieve these goals, the present invention adopts following technical scheme:
A kind of many views are taken teaching appliance, comprise camera back up pad, be positioned at camera, show stand, base in camera back up pad, it is characterized in that,
Camera back up pad connects the front end with square elbow, and the tail end of square elbow is connected with the first stepper motor, and the first stepper motor is arranged on stepper motor guide rail slide unit, and the first stepping motor slide rails slide unit is arranged at a side of show platform upper bottom surface;
Show stand is divided into show platform and little display platform, show platform is arranged on base, little display platform is positioned at the through hole of show platform, the little display platform back side is connected with the second stepper motor by turning axle, and the center of little display platform front center and camera back up pad is in the same plane perpendicular to show stand.
The present invention compared with prior art, has significant advantage: (1) can build three-dimensional relationship between line, face voluntarily, and can multi-angle show existing model; (2) utilize the first stepper motor and square elbow, control camera rotation and lifting, realize the shooting of the multiple views to model; (3) the present invention assembles, dismantles all more convenient.
Brief description of the drawings
Fig. 1 is overall construction drawing of the present invention;
Fig. 2 is show platform vertical view;
Fig. 3 is little display platform vertical view;
Fig. 4 is show platform and little display platform combination schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, illustrate the many views of one provided by the present invention and take teaching appliance.
A kind of three-view diagram is taken teaching appliance, comprises camera back up pad 1, is positioned at camera, show stand, base 9 in camera back up pad 1;
Square elbow 2 is L-shaped, and front end arranges camera back up pad 1, and tail end arranges sleeve, and square elbow 2 is connected with the first stepper motor by sleeve, and square elbow 2 is axle rotation taking itself and the first stepper motor junction under the driving of the first stepper motor.The first stepper motor is arranged on stepper motor guide rail slide unit 3, the first stepper motor 13 is vertically fixed on by fixing slide unit L support 4 along stepper motor guide rail slide unit 3 in one jiao of guide rail slide unit 3 of show stand upper bottom surface establishes ball-screw, by ball-screw, gyration is converted into rectilinear motion and slides up and down along stepper motor guide rail slide unit 3 for the first stepper motor 13
Show stand is divided into the rectangular show platform of upper bottom surface 5 and is cylindrical little display platform 15, stepper motor guide rail slide unit 3 is positioned at show platform 5 upper bottom surface one side show platforms 5 and is fixed on base 9 by studdle 11 and set nut 10, show platform 5 arranges manhole 5-1 between two parties, and little display platform 15 is positioned at the through hole 5-1 of show platform 5.Little display platform 15 bottom surfaces are connected with the second stepper motor 7 by turning axle 6, turning axle 6 is thrust ball bearing, the second stepper motor 7 is fixed on base 9 by fixed electrical machinery L support, and the center of little display platform 15 upper bottom surface centers and camera back up pad 1 is in the same plane perpendicular to show stand.
Show platform 5 upper bottom surfaces arrange three above shrinkage pool 5-2 uniformly, utilize these shrinkage pools 5-2 to coordinate thin bar and flat board can build voluntarily three-dimensional relationship between line, face.In use, represent respectively line and face with thin bar and thin flat plate, 5 preset a series of shrinkage pools on show platform, can be by stablizing the residing position of thin bar with thin bar bottom phase fit, in like manner, in thin flat plate bottom also remaining can with the projection of aperture on show stand to fit, can stablize the residing position of thin flat plate.
White pmma plate 13 is fixed on the upper bottom surface of show platform 5 by glass clamp 12, glass plate 13 is positioned at the opposite of the first stepping motor slide rails slide unit 3.
In order to prevent that circuit is interfered, on base 9, be placed with circuit box and power supply, circuit box the inside is placed driver and the single-chip microcomputer of the first stepper motor, stepper motor guide rail slide unit 3 and the second stepper motor 7 successively, motor switch is placed on circuit box water jacket, and circuit box and power supply are fixed by bolts on base 9.
Square elbow 2 is the rotation taking the vertical line perpendicular to itself and the first stepper motor junction as axle under the driving of the first stepper motor, and square elbow 2 drives camera back up pad 1 to rotate.
Little display platform 15 under the driving of the second stepper motor at the Plane Rotation at show platform 5 places.
The concrete three direction views of the present invention are taken step and are:
Step 1, places horizontal level by camera, and the plane parallel show platform 5 at dull and stereotyped 1 place of camera, now takes a figure as front view;
Step 2, utilizes programmed control the first stepping driven by motor square elbow to turn clockwise 90 ° of planes to dull and stereotyped 1 place of camera perpendicular to show platform 5, now takes a figure as left view;
Step 3, utilizes programmed control the first stepping driven by motor square elbow to be rotated counterclockwise 180 ° of planes to dull and stereotyped 1 place of camera perpendicular to show platform 5, now takes a figure as right view;
Step 4, little display platform 15 is driven and is turned clockwise 90 ° by the second stepper motor 7, now takes a figure as front view;
