Description
Technical field
The utility model belongs to teaching aid technical field, is specifically related to a kind of roughness and intuitively identifies teaching aid.
Background technology
In mechanics, roughness refers to the microcosmos geometric shape characteristic formed compared with Small Distance and peak valley that finished surface has.The fiting property, wearing quality, fatigue strength, contact stiffness, vibration & noise etc. of surfaceness and mechanical component have substantial connection, material impact is had to serviceable life of engineering goods and reliability, therefore, in teaching, roughness is an important concept.But, can only literal statement be carried out in current teaching, student can not be allowed to experience intuitively, cause student's impression more shallow.
Utility model content
For above-mentioned problems of the prior art, the utility model provides a kind of roughness intuitively to identify teaching aid, and this teaching aid structure is simple, can provide the vision about roughness and touch feeling.
For achieving the above object, the utility model provides following technical scheme:
A kind of roughness intuitively identifies teaching aid, comprise the iron plate that axis is different with surfaceness, the side of described iron plate is provided with connecting pin, described connecting pin is arranged at the diverse location of iron plate side, described connecting pin is provided with connecting hole, described axis is flexibly connected with iron plate through described connecting hole, and the two ends of described axis are provided with block piece.
Further, described iron plate is the one in triangle, quadrilateral, hexagon.
Further, described iron plate is provided with the label representing roughness grade number.
Further, the number of described connecting pin is 1-2.
Further, described 2 connecting pins are symmetrical arranged.
Further, described block piece is nut.
The beneficial effects of the utility model are as follows:
1, teaching aid of the present utility model comprises the iron plate of different roughness, can provide about roughness vision and touch feeling intuitively, make a profound impression to student;
2, the utility model is skillfully constructed, and structure is simple, is convenient for carrying.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is foldable structure schematic diagram of the present utility model;
Fig. 3 is the iron plate structural representation with 2 connecting pins of the present utility model;
Fig. 4 is the iron plate structural representation with 1 connecting pin of the present utility model.
Embodiment
The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing of the present utility model; clear, complete description is carried out to the technical solution of the utility model; based on the embodiment in the application; other roughly the same embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all should belong to the scope of the application's protection.
Embodiment one:
As shown in Figure 1 and Figure 2, a kind of roughness intuitively identifies teaching aid, comprises axis 1 iron plate different with surfaceness 2, and described iron plate 2 is quadrilateral.The utility model is skillfully constructed, and structure is simple, is convenient for carrying.
Described iron plate 1 can also be the one in triangle, hexagon.
As shown in Figure 3, Figure 4, the side of described iron plate 2 is provided with connecting pin 21, the number of described connecting pin 21 is 1 or 2, as being 2 connecting pins 21, then described 2 connecting pins are symmetrical arranged, described connecting pin 21 is arranged at the diverse location of iron plate 2 side, and the connecting pin 21 of different iron plate 2 is arranged in order along axis 1, and described iron plate 2 is provided with the label 23 representing roughness grade number.Described connecting pin 21 is provided with connecting hole 22, and described axis 1 is flexibly connected with iron plate 2 through described connecting hole 22, and the two ends of described axis 1 are provided with screw thread, take nut as block piece, stops that iron plate 2 is from landing axis 1.Teaching aid of the present utility model comprises the iron plate 2 of different roughness, can provide about roughness vision and touch feeling intuitively, and with its to grade contrast, make a profound impression to student.
In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
