Abstract
The utility model relates to a plane mechanism demonstrator which belongs to a teaching apparatus, which is composed of shelf connecting rods A and B, a machine frame, a connecting rod 2, a slide block 3, a guide rod 4, a handle, an axial supporting seat and the supporting rod of the guide rod. The shelf connecting rods A and B are connected by the connecting rod 2. The shelf connecting rod A is rotated for driving the connecting rod 2 to pull the slide block 3 to move to make the slide block 3 do reciprocating movement on the guide rod 4 for achieving the goal of demonstrating each plane mechanism. The utility model can be used for teaching for secondary technical schools.
Description
The utility model relates to a kind of plane mechanism demonstration device, belongs to instruments used for education.
Existing relevant demonstration lesson utensil can only be demonstrated single mechanism, and as slider-crank mechanism, linkage etc. is returned on the plane.The material that uses mostly is timber, moulds firmly, and bakelite etc. are made coarsely, and motion has some setbacks, and not hard solid durable, each member length can not be adjusted, and demonstration is moved unintelligible, is difficult to adapt to the requirement of modern teaching.
The purpose of this utility model provides a kind of motion principle that can demonstrate multiple plane mechanism, and the instruments used for education of kinetic characteristic and power performance translate numerous and diverse didactics to reach ocular demonstration, to drill, and makes it easily religion and easily learns raising teaching efficiency and quality of instruction.
The technical solution of the utility model is: have the plane mechanism demonstration device of mounting, and by side link A, side link B, frame 1, connecting rod 2, slide block 3, guide rod 4, handle 5, axle supporting base 6 and guide rod cramp bar 7 are formed, and side link A wherein is connected with connecting rod 2 with side link B, and the distance of its length and frame 1 (i.e. distance between two rotation axiss) can be adjusted, 3 motions of side link A rotation drivening rod 2 pulling slide blocks move back and forth slide block 3 on guide rod 4.
The utility model can be demonstrated multiple plane mechanism: crank and rocker mechanism (Fig. 1), double rocker mechanism (Fig. 2), double-crank mechanism (Fig. 3), slider-crank mechanism (Fig. 4), offset slider-crank mechanism (Fig. 9), oscillating guidebar mechanism (Fig. 5), whitworth mechanism (Fig. 6), he Moving Leader Mechanism (Fig. 8) and cranking block mechanism (Fig. 7).The kinetic characteristic that can demonstrate: quickreturn characteristics, crank angle between two limit positions, dead-centre position and drive line angle (or pressure angle).Can demonstrate the kinematic pair of mechanism: rotary pair, moving sets.When demonstrating various mechanism, can be in arbitrary stationkeeping.All member is made through machining with metal.
In the operation, during the demonstration crank and rocker mechanism: with hand fixed handle 5, side link A rotation drives side link B by connecting rod 2 and swings, and demonstrates out various motion principles.During the demonstration slider-crank mechanism: turning handle 5, side link A rotation, drivening rod 2 spurs slide block 3 motions, and slide block 3 is moved back and forth on guide rod 4, plays the effect of the various principles of demonstration.
The utlity model has following characteristics: 1. function is many, can demonstrate nine kinds of plane mechanisms and kinetic characteristic and kinematic pair.2. all member is made with metal and through machining, and the kinematic accuracy height is sturdy and durable, aesthetic in appearance.3. demonstrate different institutions, only need suitably to adjust each pole length and the several members of displacement, convenient and swift.4. same mechanism can change all lengths, observes its motion and performance, and 5. various mechanisms can be in arbitrary stationkeeping.
Now in conjunction with the accompanying drawings, be illustrated:
Fig. 1, the crank and rocker mechanism planimetric map
Fig. 2, the double rocker mechanism planimetric map
Fig. 3, the double-crank mechanism planimetric map
Fig. 4, the slider-crank mechanism planimetric map
Fig. 5, the oscillating guidebar mechanism planimetric map
Fig. 6, the whitworth mechanism planimetric map
Fig. 7, the cranking block mechanism planimetric map
Fig. 8, the he Moving Leader Mechanism planimetric map
Fig. 9, the offset slider-crank mechanism planimetric map
Among the figure, the A-side link, the B-side link, the 1-frame, the 2-connecting rod, the 3-slide block, the 4-guide rod, the 5-handle, 6-axle supporting base, 7-guide rod cramp bar, arrow shows rotation direction.
During the demonstration crank and rocker mechanism: turning handle 5, side link A rotation drives side link B by connecting rod 2 and swings.During the demonstration slider-crank mechanism: turning handle 5, side link A rotates, and 3 motions of connecting rod 2 pulling slide blocks move back and forth slide block 3 on guide rod 4, play the effect of the various plane mechanisms of demonstration.
