Problems solved by technology

This utility model patent solves the problem that the teacher has no physical reference when speaking. Due to the abstraction, many students cannot imagine the shape and structure of other views, which brings certain difficulties to teaching.
[0004] However, the parts storage platform of this projection platform device can only complete the projection of a single surface after the parts are placed. When the next surface is projected, the parts storage platform must also be lowered to a height that is convenient for manual surface replacement. After changing the surface manually, adjust the relative height of the three screws again so that the parts storage platform, convex lens and lighting lamp are located on the same horizontal plane for projection. In use, each projection surface needs to be placed manually, and the three The relative heights of the two screws are adjusted multiple times. In addition, when performing orthographic projection, it is difficult to ensure that the six surfaces are perpendicular to the emission direction of the light source by manual placement. The manual labor intensity is high and the work efficiency is low.

[0027] The workpiece clamping units are arranged around the workpiece transfer table 7, and the two workpiece clamping units are respectively used to clamp two vertical surfaces of the workpiece.

[0028] The workpiece transfer table 7 includes a box body, a light source 8 for emitting light is arranged on the bottom surface of the box, and a spotlight bowl 9 for spotlighting is arranged above the light source 8. The light source 8 is located in the center hole of the spotlight bowl ...

Embodiment 2

[0040] As a further optimization scheme based on Embodiment 1, in this embodiment, the position of the projection cloth 14 is adaptively adjusted so as to meet the adjustment requirements of the size of the workpiece or the light.

[0041] Specifically, such as image 3 As shown, a groove is provided on the side of the column 12 close to the base 17, and a height adjustment unit is arranged in the groove, so that the height of the projection cloth 14 can be changed under the action of the height adjustment unit.

[0042] Further, the height adjustment unit includes a screw rod 15 mounted in the groove through a bearing, one end of the screw rod 15 is connected with the output shaft of the drive device 16 through a coupling, the screw rod 15 is sleeved with a nut seat, and the nut seat A moving block 13 is fixedly connected to the top, and the moving block 13 is connected to the support frame of the projection cloth 14 by connecting bolts.

[0043] Wherein, the driving device ...

Embodiment 3

[0045] As a further optimization solution on the basis of Embodiment 2, in this embodiment, the position of the turntable 7 in the workpiece is adaptively adjusted so as to meet the adjustment requirements of the size of the workpiece or the light.

[0046] Specifically, a lift adjustment unit 10 is provided below the workpiece transfer table 7 , one end of the lift adjustment unit 10 is fixed to the bottom surface of the workpiece transfer table 7 , and the other end of the lift adjustment unit 10 is fixed to the base 17 .

[0047] Wherein, the lift adjustment unit 10 may preferably be one of a hydraulic cylinder or a fork lift.

[0048]In use, the telescopic unit one 5 of one of the workpiece clamping units is extended to the work area directly above the workpiece turntable 7, and then the telescopic unit two 2 is synchronously driven to adjust the opening of the clamping structure to facilitate clamping the workpiece, and then synchronously Drive the two driving devices 1-3...

Abstract

The invention relates to a mechanical drawing view projection platform device, and belongs to the technical field of auxiliary equipment for mechanical teaching. The mechanical drawing view projectionplatform device comprises a workpiece transfer table and two workpiece clamping units; each workpiece clamping unit comprises a supporting body; a first telescopic unit is arranged at the top end ofeach supporting body; a bracket is arranged at the tail end of a telescopic body of each first telescopic unit; a clamping structure for clamping a workpiece is arranged on each bracket; the workpiececlamping units are arranged around the workpiece transfer table; and clamping faces of the clamping structures of two workpiece clamping units, which are used for clamping the workpiece, are perpendicular to each other. The clamping structures of the mechanical drawing view projection platform device is adjustable in opening; meanwhile, the workpiece transfer table is adjustable in height and canbe applicable to projection demands of different sizes of workpieces; and according to the mechanical drawing view projection platform device, projection of all faces can be completed without manually participating in changing faces, so that hand labor intensity is reduced and the mechanical drawing view projection platform device is high in working efficiency, high in practicality and valuable to popularize.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for mechanical teaching, and in particular relates to a mechanical drawing view projection platform device. Background technique [0002] In the professional courses of mechanical manufacturing and related majors, the mechanical drawing course is indispensable as a professional basic course. In the teaching process of mechanical drawing, the drawing of views is a difficult point. Many students who do not have a strong sense of space find it difficult to construct three-dimensional graphics in their minds. Therefore, it is very difficult to learn drawing views, and the learning effect of students is relatively poor. [0003] In the utility model patent with the application number CN201621013609.3, a mechanical drawing view projection platform device is disclosed. Its structure includes a flat plate fixed on the top wall of the classroom and a blackboard fixed on the side wall of the cla...
