Problems solved by technology

[0003] The current teaching of CNC technology generally adopts the teaching method of combining classroom theory teaching and CNC machine tool practice. Because it is difficult to put CNC machine tools on the platform, theory teaching and practice are two independent teaching links, and the two cannot be integrated in time.

Embodiment 1

[0036] Such as Figure 1-14 shown.

[0037] A kind of numerical control whiteboard plotter for teaching, such as figure 1As shown, it can be used in conjunction with CAD software such as AutoCAD, CAXA, and the numerical control mode is open-loop control. Shaped slide plate 50, Γ-shaped slide plate 50 is pulled by the wire rope in the transverse traction system 30, and moves horizontally along the transverse guide rail 40; Electromagnetic pen holder assembly 70 is installed on described Γ-shaped slide plate 50 and drives this electromagnetic pen holder assembly 70 The longitudinal traction system 60 moving up and down, the electromagnetic pen holder assembly 70 , the transverse traction system 30 and the longitudinal traction system 60 are all controlled by the numerical control system 80 . The installation frame 20 is fixed on the rear portion of the whiteboard and is used to fix the whiteboard plotter on the wall or support it on the ground so that the whiteboard is paralle...

Embodiment 2

[0047] Such as Figure 1-14 shown.

[0048] The structure of the digitally controlled whiteboard plotter for teaching in this embodiment is generally the same as that in Embodiment 1, but the numerical control mode is closed-loop control. On the premise that the embodiment is substantially the same as the first embodiment described above, the following changes are made.

[0049] Horizontal hanging wheel assembly 303 such as Figure 5 As shown, it includes a wire sheave 3031 , a hanging sheave bracket assembly 3032 , a shaft coupling 3033 and a rotary encoder 3034 . The hanging wheel bracket assembly 3032 includes a bearing assembly 303201 and a Ц-shaped frame body 303202. The shaft of the wire sheave 3031 passes through the bearing assembly 303201, and is connected with the input shaft of the rotary encoder 3034 through the coupling 3033, and the shell of the rotary encoder 3034 is fixed on the Ц-shaped frame body 303202.

Abstract

Provided is a numerical control whiteboard potter for teaching. The numerical control whiteboard plotter for teaching comprises a whiteboard (10). The numerical control whiteboard plotter for teaching is characterized in that a lateral guide rail (40) is arranged at the upper end or the lower end of the whiteboard, an inverted L-shaped or L-shaped slide board (50) is arranged on the lateral guide rail (40), and the slide board (50) is driven by a steel wire rope in a lateral traction system (30) and moves in a horizontal direction along the lateral guide rail (40); an electromagnetic penholder assembly (70) and a longitudinal traction system (60) which drives the electromagnetic penholder assembly (70) to move upward and downward are arranged on the slide board (50), the electromagnetic penholder assembly (70), the lateral traction system (30) and the longitudinal traction system (60) are all controlled by a numerical control system (80). The numerical control whiteboard potter for teaching provides intuitive teaching aids for curricular teaching of engineering drawing, numerical control principle and the like, and therefore learning interest and quality of teaching are improved.

Description

technical field [0001] The invention relates to a teaching instrument, especially a plotter for directly drawing on a whiteboard matched with computer-aided drawing (CAD) software, such as AutoCAD, CAXA, etc., specifically a numerical control whiteboard drawing for teaching instrument. Background technique [0002] At present, many courses in engineering technology majors need to draw on the blackboard. Although multimedia classrooms combined with computer drawing software can also be used for graphic demonstration, computer drawing can only display the final graphic results, and it is difficult to demonstrate drawing intuitively like manual drawing. process. A device that can automatically draw on a blackboard (or whiteboard) in a classroom does not currently exist. The invention uses two-axis numerical control technology to fill this technical gap, and provides a low-cost teaching device that can vividly display the principle of numerical control technology. [0003] Th...
