Abstract

The invention provides a teaching demonstration instrument of tolerance principles. The teaching demonstration instrument comprises a teaching demonstration device of dimensional tolerance, a teaching demonstration device of geometrical tolerance, a teaching demonstration panel and two hole-shaft teaching demonstration boards simulating holes or shafts, wherein the hole-shaft teaching demonstration boards are parallelly arranged in the horizontal direction; the teaching demonstration device of dimensional tolerance comprises a translation transmission mechanism for driving the hole-shaft teaching demonstration boards to perform vertical translation to simulate and demonstrate the change of the dimensional tolerance of holes or shafts, and a dimensional-tolerance transmission mechanism for displaying the dimensional tolerance which is simulated and demonstrated by the hole-shaft teaching demonstration boards on the teaching demonstration panel, and the dimensional-tolerance transmission mechanism is connected with the translation transmission mechanism in a driving manner; the teaching demonstration device of geometrical tolerance comprises a deflection transmission mechanism for driving the hole-shaft teaching demonstration boards to simulate and demonstrate the change of the geometrical tolerance of holes or shafts in a deflection manner, and a geometrical-tolerance transmission mechanism for displaying the geometrical tolerance which is simulated and demonstrated by the hole-shaft teaching demonstration boards on the teaching demonstration panel, and the geometrical-tolerance transmission mechanism is connected with the deflection transmission mechanism in a driving manner. The teaching demonstration instrument disclosed by the invention has the advantage that the tolerance principles can be visually and intuitively simulated and demonstrated.

Description

technical field [0001] The invention relates to a teaching instrument, in particular to a tolerance principle teaching instrument. Background technique [0002] The tolerance principle is an important design principle dealing with the relationship between dimensional tolerances and shape tolerances, which mainly includes: independent principles and related requirements (inclusive requirements, maximum physical requirements, minimum physical requirements and reversible requirements). In the existing teaching of mechanical precision design courses, tolerance principles are usually explained from the level of theoretical definition by means of text descriptions, formulas, and graphic expressions, and there is a lack of visual and intuitive physical teaching and demonstration instruments. Since the tolerance principle involves many and abstract definitions of concepts, it is easy to be confused and difficult to understand when learning. Contents of the invention [0003] The ...
