Description
Technical field：
The present invention relates to a kind of six bars to become input linkage experimental bench, belongs to controllable mechanism experimental technique field.
Background technology：
With the development of society, the frequency that linkage occurs in industrial or agricultural is increasing, effect becomes increasingly conspicuous, now
Also just towards multi link, multiple degrees of freedom, it is controllable in terms of develop.And teaching experiment platform now is mostly by DC MOTOR CONTROL list
Free degree mechanism, it is impossible to the features such as on-line continuous is controllable, and also system is big, and manufacturing cost is high, it is impossible to meet the need of social development
Ask, application scenario is also extremely limited.
The content of the invention：
The present invention is that the technical scheme of the use to solve the above problems is：A kind of six bars become input linkage experimental bench,
It is characterized in that by bottom plate, the first stepper motor, the second stepper motor, the 3rd stepper motor, bearing block, shaft coupling, axle, axle
Hold, be bearing cap, first connecting rod, second connecting rod, third connecting rod, fourth link, guide rail, feed screw nut, screw mandrel, gear, snap ring, double
Cross extension coupling, vibration sliding block, bolt member composition, first connecting rod, second connecting rod, third connecting rod, fourth link, guide rail
Between be connected successively with hinge, feed screw nut with vibration sliding block be connected with bolt.
The present invention is rotated using the first stepper motor and the second stepper motor, so as to which drivening rod moves, while the 3rd step
Stepper motor rotation drives the vibration sliding block being connected with connecting plate to be moved back and forth on guide rail, three step motor controls, three freedom
Degree, realize that multiple-degree-of-freedom mechanism has the motion uniquely determined；Control the rotating speed of three stepper motors respectively using program, realize
The controllability of motion；Solved well between the second stepper motor and fourth link rotation using diesis extension coupling
Movement interference problem, has an online continuous adjustment for not shutting down forms of motion, multipurpose, it is compact-sized, attractive in appearance, easy to assembly,
The features such as manufacturing cost is low.
Brief description of the drawings：

Fig. 2：A kind of six bars become input linkage experimental bench schematic diagram
Embodiment：
The present invention is further described with reference to the accompanying drawings and examples.
A kind of six bars become input linkage experimental bench, it is characterised in that by bottom plate (19), the first stepper motor (1), the
Two stepping motor (7), the 3rd stepper motor (18), bearing block (3), axle (2), bearing (4), bearing cap (5), first connecting rod (9),
Second connecting rod (10), third connecting rod (11), fourth link (12), guide rail (17), feed screw nut (15), screw mandrel (13), gear
(6), the part composition such as diesis extension coupling (8), vibration sliding block (16), bolt (14).
Wherein the first stepper motor (1) drives first connecting rod (9) to rotate by axle (2), and the second stepper motor (7) passes through tooth
Take turns (6) and diesis extension coupling (8) driving fourth link (12) rotates, the 3rd stepper motor (18) is driven by screw mandrel (13)
Dynamic feed screw nut (15) is moved back and forth, feed screw nut (15) is connected with bolt (14) with vibration sliding block (16).First stepper motor
(1), the second stepper motor (7) and the 3rd stepper motor (18) respective rotating speed are individually controlled by program, utilize the first stepping electricity
Machine (1), the difference of the second stepper motor (7) and the 3rd stepper motor (18) rotating speed and mutual cooperation, realize the line not company of shutdown
The forms of motion of continuous adjustment six bar mechanism, realize that six bar mechanism becomes input experimental study.
Second stepper motor (7) drives fourth link (12) to rotate by gear (6) and diesis extension coupling (8),
Here solves the motion between the second stepper motor and fourth link (12) rotation well using diesis extension coupling
Interference problem, this is the technical barrier that six bar mechanism is realized.
