Embodiment Construction

[0007] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0008] A six-bar three-input linkage teaching aid is characterized in that it consists of a base plate (19), a first stepping motor (1), a second stepping motor (7), a third stepping motor (18), a bearing seat ( 3), shaft (2), bearing (4), bearing cover (5), first connecting rod (9), second connecting rod (10), third connecting rod (11), fourth connecting rod (12) , guide rail (17), screw nut (15), screw mandrel (13), gear (6), double cross telescopic coupling (8), vibrating slider (16), bolt (14) and other components.

[0009] The first stepper motor (1) drives the first connecting rod (9) to rotate through the shaft (2), and the second stepper motor (7) drives the fourth through the gear (6) and the double cross telescopic coupling (8). The connecting rod (12) rotates, and the third stepper motor (18) drives the screw nut (15) to reciprocate through ...

Abstract

A six-rod three-input connecting rod mechanism teaching aid is composed of a bottom plate, a first stepping motor, a second stepping motor, a third stepping motor, a bearing seat, a coupling, a shaft,a bearing, a bearing cover, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a guide rail, a screw nut, a screw rod, gears, a snap ring, a double cross telescopic coupling, a vibration sliding block and bolts; and the first connecting rod, the second connecting rod, the third connecting rod, the fourth connecting rod and the guide rail are sequentially connected through hinges, and the screw nut and the vibration sliding block are connected through the bolts. Rotating speeds of the three stepping motor are respectively controlled by utilizing acontrol program, and then motion controllability is achieved; and the problem of motion interference between the second stepping motor and the fourth connecting rod while rotation is performed is solved well through adoption of the double cross telescopic coupling, continuous adjustment in an online non-stop motion manner is achieved, and the six-rod three-input connecting rod mechanism teachingaid has the advantages of multiple functions, compact structure, beautiful appearance, convenient assembly, low manufacturing cost and the like.

Description

Technical field: [0001] The invention relates to a teaching aid for a six-bar three-input linkage mechanism, which belongs to the technical field of machinery. Background technique: [0002] With the development of society, the link mechanism appears more and more frequently in industry and agriculture, and its role is becoming more and more prominent. Now it is also developing towards multi-link, multi-degree-of-freedom, and controllable. Today's teaching and experiment platforms are mostly single-degree-of-freedom mechanisms controlled by DC motors, which cannot be continuously controlled online. They also have the characteristics of large systems and high manufacturing costs, which cannot meet the needs of social development and have very limited applications. Invention content: [0003] The technical solution adopted by the present invention to solve the above problems is: a six-bar three-input linkage teaching aid, characterized in that it consists of a base plate, a ...
