Abstract
The utility model discloses a kind of cam mechanism page plate.Mechanical principle course is abstract, and mechanical principle mechanism Display Rack price is high, and Portable belt not.The utility model comprises transparent coating, top book frame, Ye Ban mechanism, base plate, active thumb wheel, driven thumb wheel and transmission thumb wheel; Top book frame and base plate are bonding, and initiatively all and base plate hinged, and initiatively thumb wheel engages with transmission thumb wheel for thumb wheel, driven thumb wheel and transmission thumb wheel, and transmission thumb wheel engages with driven thumb wheel; Initiatively a side of thumb wheel is exposed the side of Ye Ban mechanism; Transparent coating is bonded on the book frame of top, is printed on knowledge section title, cam drive basic parameter and cam locus curve on transparent coating; Ye Ban mechanism comprises cam and push rod, and push rod is connected by sliding pair with base plate; Cam and base plate hinged, and the lower surface of cam and the upper surface of driven thumb wheel are fixed.The utility model becomes the cam mechanism in mechanical principle course into stereoscopic mechanism, intuitively lively.
Description
Technical field
The utility model belongs to educational aid field, relates to textbook, is specifically related to a kind of cam mechanism page plate.
Background technology
Show by inquiry, it is too abstract that each large college student generally reacts mechanical principle course, and classroom indigestion causes achievement not increase.Although for this problem, most of industry science class colleges and universities have all been equipped with mechanical principle mechanism Display Rack, extracurriliar or visit while testing for students, be intended to serve better student and learn mechanical principle course well.But Display Rack exists two defects, on the one hand, Display Rack is expensive, and a Display Rack just needs fund up to ten thousand, and the mechanism of mechanical principle has a lot, has increased burden to the infusion of financial resources of school, mechanical principle course.On the other hand, Display Rack is bulky, cannot take the classroom use of attending class, and some school is even locked in laboratory by Display Rack, and student seldom has an opportunity really to touch mechanism, and the meaning of Display Rack is reduced.How to reduce costs to school, and mechanism can be taken to classroom, attend class for student, play good aided education, allow course become more vivid, allow student's study become a happy process, these problems have to be solved.Therefore, develop an operable a kind of cam mechanism page plate in this classroom, will on classroom, classroom, bring into play huge effect.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of cam mechanism page plate is provided, be applicable to the explanation of mechanical principle course cam mechanism, make cam mechanism motion by stirring the gear of books side, demonstration is lively, heighten the enjoyment to classroom, the intuitive that elevating gear principle knowledge Focal point and difficult point is lectured and interactive; Demonstrate and add basic theoretical knowledge by mechanism, cam mechanism is analyzed, designed, cultivate student's knowwhy application power, overcome stiff, the abstract problem of standard machinery principle books.
The utility model comprises transparent coating, top book frame, Ye Ban mechanism, base plate, active thumb wheel, driven thumb wheel and transmission thumb wheel; Described top book frame and base plate are bonding, described Ye Ban mechanism, active thumb wheel, driven thumb wheel and transmission thumb wheel are all arranged between top book frame and base plate, described active thumb wheel, driven thumb wheel and transmission thumb wheel are all and base plate hinged, and initiatively thumb wheel engages with transmission thumb wheel, and transmission thumb wheel engages with driven thumb wheel; One side of described active thumb wheel is exposed the side of Ye Ban mechanism; Described transparent coating is bonded on the book frame of top, is printed on knowledge section title, cam drive basic parameter and cam locus curve on transparent coating; Described Ye Ban mechanism comprises cam and push rod, and described push rod is connected by sliding pair with base plate; Described cam and base plate hinged, and the lower surface of cam and the upper surface of driven thumb wheel are fixed.
The beneficial effects of the utility model:
1, the cam mechanism in mechanical principle is carried out physical object simulating by the utility model, and be integrated in page plate, by 3 D stereo mechanism, cam locus curve and knowledge point statement combination, abstract, the complicated knowledge point of script is transformed into three-dimensional movable cam mechanism, make knowledge point become more directly perceived lively, be convenient to promote student's learning interest, for mechanical principle course teaching, make teaching process lively, vivid.
2, the utility model compact, be convenient for carrying, be convenient to change, cost is low, is highly suitable on the course (as Machine Design, Graphing of Engineering) that needs to demonstrate mechanism on colleges and universities classroom and promotes, and has higher economic worth and application value.
3, the utility model is applicable to standardization production, and production cost is low, and using value is high.
Brief description of the drawings
Fig. 1 is stereographic map of the present utility model;
Fig. 2 is the schematic diagram of transparent coating in the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As illustrated in fig. 1 and 2, a kind of cam mechanism page plate, comprises transparent coating 1, top book frame 2, Ye Ban mechanism 3, base plate 4, active thumb wheel 5, driven thumb wheel 6 and transmission thumb wheel 7; Top book frame 2 is bonding with base plate 4, Ye Ban mechanism 3, active thumb wheel 5, driven thumb wheel 6 and transmission thumb wheel 7 are all arranged between top book frame 2 and base plate 4, initiatively thumb wheel 5, driven thumb wheel 6 and transmission thumb wheel 7 are all hinged with base plate 4, and initiatively thumb wheel 5 engages with transmission thumb wheel 7, and transmission thumb wheel 7 engages with driven thumb wheel 6; Initiatively a side of thumb wheel 5 is exposed the side of Ye Ban mechanism 3, and available hand is stirred initiatively thumb wheel 5, drives driven thumb wheel 6 to move, thereby band moveable leaf plate mechanism 3 moves; Transparent coating 1 is bonded on top book frame 2, is printed on knowledge section title 8, cam drive basic parameter 9 and cam locus curve 10 on transparent coating 1; Ye Ban mechanism 3 comprises cam 3-1 and push rod 3-2, and push rod 3-2 is connected by sliding pair with base plate 4; Cam 3-1 and base plate 4 are hinged, and the upper surface of the lower surface of cam 3-1 and driven thumb wheel 6 is fixed.
The use of this cam mechanism page plate:
This cam mechanism page plate has carried out the analysis of physical object simulating and Key Points for the cam mechanism in mechanical principle; Student can stir initiatively thumb wheel 5 with hand, drives transmission thumb wheel 7 and driven thumb wheel 6 to move, thereby band moveable leaf plate mechanism 3 moves, and profoundly understands all critical learning in motion and the motion process of cam mechanism.
