A blueprint display device for mechanical design

Abstract

The invention discloses a drawing placing and displaying device for mechanical design. The device comprises a movable base, an installation cavity is formed in the movable base, a supporting rod is arranged above the movable base, the bottom of the supporting rod extends into the installation cavity, and a rotation groove is formed in the bottom of the supporting rod. A screw is in threaded connection in the rotation groove, the bottom of the screw extends into the lower side of the supporting rod, a first gear fixedly sleeves the bottom of the screw, a first driving motor is fixedly installedon the inner wall of the top of the installation cavity, a second gear is welded to an output shaft of the first driving motor, and the first gear and the second gear are rotationally connected witha same chain. The device is simple in structure, the display device body can freely move, it is convenient for a teacher to carry out flexible teaching, under the cooperation of the first driving motor and the second driving motor, the height of a display frame can be adjusted, after the height is adjusted, a design drawing can be automatically unfolded, and great convenience is brought to teaching of the teacher.

Description

technical field [0001] The invention relates to the technical field of mechanical design teaching, in particular to a device for placing and displaying blueprints for mechanical design. Background technique [0002] Mechanical design is an important part of mechanical engineering, the first step in mechanical production, and the most important factor determining mechanical performance. The goal of mechanical design is to design the best machinery under various limited conditions (such as materials, processing capabilities, theoretical knowledge and calculation methods, etc.), that is, to make optimal designs. Optimal design needs to comprehensively consider many requirements, generally including: the best working performance, the lowest manufacturing cost, the smallest size and weight, the most reliable in use, the lowest consumption and the least environmental pollution. These requirements are often contradictory, and their relative importance varies with the type and appl...

Problems solved by technology

[0003] In the teaching process of mechanical design teachers nowadays, design drawings are necessary learning content. In the process of teaching, teachers usually fix the design drawings on the blackboard with magnetic blocks, which will easily cause the design drawings to fall off. At the same time, the design drawings Unable to move the display, resulting in limited teaching and unable to take care of the students in the back row, so we proposed a display device for mechanical design drawings to solve the above-mentioned problems
