Description
Technical field
The utility model relates to a kind of track creator.
Background technology
Planar linkage mechanism experiment table for teaching and demonstration is widely used in each colleges and universities, in linkage assembly, on connecting rod, the point of diverse location can realize the link motion geometric locus enriched, different engineer applied can be met, but when demonstration realizes the kinetic characteristic of desired trajectory, cannot real-time rendering coupler-point curve, not visual pattern, be not easy to the understanding of student.
Utility model content
The purpose of this utility model, be to provide a kind of track creator, the utility model devises a kind of track creator for above deficiency, track creator is provided with paintbrush, can on drawing board real-time rendering connecting rod mechanism movement geometric locus, during use, track creator can be arranged on the diverse location of connecting rod, to draw out different link motion geometric locuses, visual in image, the grasp linkage assembly making student more deep realizes the kinetic characteristic of desired trajectory.
The technical scheme adopted is:
A kind of track creator, is arranged on the connecting rod of planar linkage mechanism experiment table for teaching and demonstration, comprises paintbrush, the pen cap, sleeve, spring, web member, it is characterized in that:
Paintbrush closely cooperates and inserts in the pen cap, pen cap outer rim there is boss, pen cap one end is through sleeve, the pen cap and sleeve form clearance fit, sleeve inside rim is stuck on the boss of pen cap outer rim, the sleeve other end links together in the mode be threaded with web member, at sleeve built with spring, spring upper end withstands on pen cap lower end, lower spring end withstands on web member upper end, there is mounting hole web member lower end, connecting rod is through mounting hole, make track creator can along rod slide, to regulate arbitrarily the distance at track creator and connecting rod two ends, draw different coupler-point curves, after track creator position is determined, lock with holding screw, so that fixation locus maker, during installation, paintbrush is made to push against drawing board, spring-compressed is made by the pen cap, under spring force effect, make paintbrush keep in touch with drawing board all the time, ensure the drafting effect of coupler-point curve.
In linkage assembly, on connecting rod, the point of diverse location can realize the link motion geometric locus enriched, the utility model can make track creator be arranged on the diverse location of connecting rod, thus ensure that different coupler-point curves drawn out by paintbrush on drawing board, visual in image, compared by the actual path curve drawn out and the calculated results, if basic indifference, illustrate reasonable in design, if difference is larger, find out reason and solve, allowing student move towards actual from theory, the ability of exercise student ' solving practical problems.Track creator is arranged on planar linkage mechanism experiment table for teaching and demonstration.See accompanying drawing 2.
Track creator is provided with paintbrush, can on drawing board real-time rendering connecting rod mechanism movement geometric locus, during use, track creator can be arranged on the diverse location of connecting rod, to draw out different link motion geometric locuses, visual in image, the grasp linkage assembly making student more deep realizes the kinetic characteristic of desired trajectory.
