Further, also comprise base plate, described projection light source, condenser group and object platform Bracket setting are on base plate.
Further, described base plate is also provided with left plate, right plate and back side panel, described left plate, right plate and back side panel are all perpendicular to base plate.
Further, above described left plate, right plate and back side panel, also top board is provided with.
Further, described condenser group is provided with at least a slice and the light of projection light source is changed into the convex lens of directional light.
Further, described object platform support bottom is provided with the lifting drive that object platform support is elevated.
Further, also comprise controller, the signal output part of described controller connects the signal control line of rotating driving device, the signal control line of lifting drive respectively.
Further, described projection screen is translucent or transparent screen.
Further, described top board is opaque baffle plate.
Compared with prior art, the beneficial effect that the utility model has is:
A kind of mechanical drawing view projections stage apparatus of the present utility model, is provided with projection light source, is provided with condenser group, object platform support, projection screen successively, object platform support is provided with rotating driving device in the printing opacity direction of projection light source.This device is as the demonstration teaching aid in mechanical major classroom, utilize the rotating driving device of object platform support, thus project in projection screen after making mock-up turn to different angles, mutual transforming relationship between each two dimensional surface view enabling student's more intuitive understanding solid model corresponding with it, greatly can improve efficiency of teaching, improve the learning interest of student, and structure is simple, cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is that signal of the present utility model controls schematic diagram.
Embodiment
Below in conjunction with embodiment, the technical solution of the utility model is described in further detail, but does not form any restriction of the present utility model.
With reference to shown in Fig. 1 ~ 3, a kind of mechanical drawing view projections stage apparatus of the present utility model, comprise projection light source 1, condenser group 2, object platform support 3, projection screen 4 is provided with successively in the printing opacity direction of projection light source 1, object platform support 3 is provided with rotating driving device 5, utilize rotating driving device 5, make object platform support 3 can realize 360 degree of rotations in surface level.The light that projection light source 1 sends, has changed into directional light through condenser group 2, exposes on the solid model on object platform support 3, then, is projected to by solid model in projection screen 4 and forms two dimensional surface view.A kind of mechanical drawing view projections stage apparatus of the present utility model is as the demonstration teaching aid in mechanical major classroom, utilize the rotating driving device of object platform support 3, thus project in projection screen 4 after making mock-up turn to different angles, mutual transforming relationship between each two dimensional surface view enabling student's more intuitive understanding solid model corresponding with it, greatly can improve efficiency of teaching, improve the learning interest of student, and structure is simple, cost of manufacture is low.
A kind of mechanical drawing view projections stage apparatus of the present utility model also comprises base plate 6, and described projection light source 1, condenser group 2 and object platform support 3 are arranged on base plate 6, like this, facilitates academics and students's this stage apparatus mobile in the process of teaching.Described base plate 6 is also provided with left plate 7, right plate 8 and back side panel 9, and left plate 7, right plate 8 and back side panel 9 are all perpendicular to base plate 6.Wherein, base plate 6, left plate 7, right plate 8 and back side panel 9 is plank, utilizes screw to connect, and by arranging left plate 7, right plate 8 and back side panel 9, makes the better effects if of ray cast.
Above left plate 7, right plate 8 and back side panel 9, be also provided with top board 10, when projecting, cover top board 10, light is more concentrated in projection platform device, and the image projected out is more clear.Front side and the top side of left plate 7 and right plate 8 are provided with stria, convenient placement top board 10.
Condenser group 2 is provided with at least a slice and the light of projection light source 1 is changed into the convex lens 11 of directional light, and the light sent in projection light source 1 is divergent rays, utilizes convex lens 11 optically focused, and diverging light congruence projection light source 1 sent becomes directional light.When projecting, make projection light source 1, condenser group 2 center and solid model center on the same line, more clear to guarantee the two dimensional surface view image projected out.
Object platform support 3 bottom is provided with the lifting drive 12 that object platform support 3 is elevated.When solid model placed by object platform support 3, because the height of each view model is not identical, utilize lifting drive 12 to regulate the height of object platform support 3, guarantee projection light source 1, condenser group 2 center and solid model center on the same line.
A kind of mechanical drawing view projections stage apparatus of the present utility model also comprises controller 13, the signal output part of described controller 13 connects the signal control line of rotating driving device 5, the signal control line of lifting drive 12 respectively, lifting and the anglec of rotation of object platform support 3 can be controlled by controller 13, make the more convenient operation of whole teaching demonstration process.
Projection screen 4 is translucent or transparent screen, like this, can be convenient to the two dimensional surface view observing solid model.Top board 10 is opaque baffle plate, and light is more concentrated in projection platform device, and the image projected out is more clear.
The foregoing is only better embodiment of the present utility model, all do in spirit of the present utility model and spirit any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
