Abstract
The present invention relates to one kind to become length linkage instructional device, is made up of supporting table, the first controlled motor, the second controlled motor, the 3rd controlled motor, shaft coupling, diesis Hooks coupling universal coupling, the first side link, the second side link, variable length link connecting rod, plain connecting rod, sliding block, guide rail.Becoming length linkage instructional device realizes the adjustable function of amplitude on-line continuous of double crank slider mechanism exciting agency, by realizing the change of length of connecting rod, avoids frequent disassembling, assembling and replacing connecting rod, is easy to teaching demonstration and experiment.It is simple in construction, easily realize, small volume, mechanical major teaching field can be advantageously applied to.
Description
Technical field
The present invention relates to one kind to become length linkage instructional device, belongs to mechanical test technical field.
Background technology：
Conventional mechanical exciting agency using single crank slide block mechanism eccentric stiffener, cam mechanism, have equipment it is simple,
The advantages of price is low, easy to use, but the problems such as excited frequency is single, and amplitude adjustment is difficult be present, it is difficult to realize ungraded amplitude
Exported with more frequency vibrations；Double crank slider mechanism exciting agency can realize that amplitude on-line continuous adjusts, and have mechanical exciting
The characteristics of cost of mechanism is low, easy to use while the performance for improving mechanical exciting agency.
Conventional linkage experimental bench is usually quadric chain, can not realize the function of exciting agency, using
Rod member is changed, to adapt to the length requirement that different real rod members are tested, this experimental bench needs to prepare a large amount of connecting rods to be used in case changing,
And need constantly to dismount rod member in experimentation, experimental implementation is inconvenient, is also easily damaged rod member.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of religion of the connecting rod with exciting function of adjustable link length
Learn device.The present invention solves above-mentioned technical problem using following technical scheme：One kind becomes length linkage instructional device, by propping up
Support platform, the first controlled motor, the second controlled motor, the 3rd controlled motor, shaft coupling, diesis Hooks coupling universal coupling, the first frame linking
Bar, the second side link, variable length link connecting rod, plain connecting rod, sliding block, guide rail composition；Wherein the first side link, the second frame linking
Bar is connected with variable length link with hinge.Variable length link is by two sections of rod members and forms, and U-shaped block is connected by trip bolt
It is connected on rod member.
It is real to become the variable linkage of the length of connecting rod that is made up of double crank slider mechanism of length linkage instructional device
Platform is tested, the function of exciting agency can be achieved, changes the length of connecting rod by adjusting trip bolt, it is not necessary to rod member is changed, with suitable
The demand of different experiments is answered, it is easy to operate, it is simple in construction.
Brief description of the drawings
Fig. 1：The structural representation of the variable linkage instructional device of length of connecting rod.
Fig. 2：Variable length link structural scheme of mechanism.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
As shown in figure 1, the present invention is by supporting table (19), the first controlled motor (1), the second controlled motor (7), the 3rd controlled
Motor (18), shaft coupling (2), diesis Hooks coupling universal coupling (8), the first side link (9), the second side link (12), variable-length
Connecting rod connecting rod (10), plain connecting rod (11), sliding block (13), guide rail (17) etc. form.Wherein the connecting rod of variable-length is by rod member 1
(1) it is connected to rod member 2 (5), U-shaped block (2), trip bolt composition, U-shaped block (2) by trip bolt (3) on rod member 2 (5).
When trip bolt (4) unclamps, connecting rod 1 (1) can relatively move in U-shaped block (2)；When being moved to the length of needs, lead to
Cross and tighten screw (4), to fix the length of connecting rod.The change of length of connecting rod is realized by this method, avoids the frequently company of replacing
Bar.
By supporting table (19), the first controlled motor (1), the second controlled motor (7), the 3rd controlled motor (18), shaft coupling
(2), diesis Hooks coupling universal coupling (8), the first side link (9), the second side link (12), variable length link connecting rod (10), general
Lead to the linkage instructional device of the compositions such as bar (11), sliding block (13), guide rail (17), the function of exciting agency can be achieved, lead to
Cross the length that adjustment trip bolt changes connecting rod, it is not necessary to change rod member, easy to operate to adapt to the demand of different experiments, knot
Structure is simple.
Claims (1)
1. one kind becomes length linkage instructional device, by supporting table, the first controlled motor, the second controlled motor, the 3rd controlled
