Tool microscope teaching board

Abstract

The invention relates to a tool microscope demonstration and teaching board. The tool microscope demonstration and teaching board comprises an upper bottom plate and a lower bottom plate, wherein an intermediate dial is arranged between the upper bottom plate and the lower bottom plate, the outer circle of the intermediate dial is positioned by means of a cylindrical pulley and a cylindrical pulley sleeve which are installed on the upper bottom plate, and the intermediate dial can rotate along a pulley column; the upper surface of the lower bottom plate is connected with a cross-shaped sliding block through sliding grooves in the two sides, the upper surface of the cross-shaped sliding block is connected with a horizontal sliding plate via a sliding groove, the horizontal sliding plate can slide along the horizontal direction of the sliding groove of the cross-shaped sliding block, a threaded plate is fixed to the middle part of the upper surface of the horizontal sliding plate by means of a magnet, slotted parts in the middle of upper and lower parts of the lower bottom plate are each connected with a pulley by means of a pulley bracket and a pulley shaft pin, and both ends of a flexible rope are wound around the two pulleys and then connected with the cross-shaped sliding block after tensioning; and the upper bottom plate and the lower bottom plate are fixed together by means of bolts and threaded columns. The tool microscope demonstration and teaching board has a demonstration and teaching range equal to that of a tool microscope, can be used for demonstrating and teaching projects of measuring pitch diameter of thread, thread pitch error, flank angle error, sample board geometric angle, outer circle diameter, hole centre distance, taper angle, slope, groove width, length and the like.

Description

technical field [0001] The invention relates to a mechanical teaching teaching board, in particular to a tool microscope teaching board with the same teaching range as the tool microscope, capable of teaching and measuring thread diameter, pitch error, flank angle error, template geometric angle, outer circle Diameter, hole center distance, taper angle, slope, groove width, length and other items. Background technique [0002] Tool microscopes are divided into large, small, universal and other types. Tool microscopes can be used to measure lengths and angles, and inspect complex-shaped parts such as turning tools, gear shapers, thread plug gauges, templates and other tools and measuring tools. Especially in thread measurement, it is often used. The most commonly used tool microscope is to measure thread pitch, thread diameter, thread half angle, etc. The tool microscope uses the principle of light transmission and reflection to magnify and project the workpiece to be measur...

AI Technical Summary

Problems solved by technology

In the past, a classmate designed and produced a tool microscope eyepiece teaching instrument, but due to some defects in its design, it made it difficult for the teacher to teach and operate, and it was not vivid enough, and it could not meet the requirements of large class teaching

[0003] At present, in the teaching process of the tool microscope, the traditional method is that the teacher takes a tool microscope teaching board as a demonstration case and explains it directly. Because the microscope is too small, it cannot be effectively and directly explained.

The existing technology is to use three-dimensional simulation animation to play the method of using the tool microscope on the computer, but it cannot be operated by hand, and its time performance is lost.
