The purpose that idle running is suddenly returned.
Existing slider-crank mechanism specifically, is generally included with lower structure：Crank, connecting rod, sliding block and slide bar, sliding block
Sliding sleeve is on slide bar, articulated linkage one end on sliding block, and the connecting rod other end is hinged crank one end, and the crank other end is in linkage with motor
Main shaft.Motor rotation drives crank to rotate, and the sliding block of articulated linkage is moved as crank is rotated on slide bar.
The straight line slide unit for science and education experiment has the disadvantage that in the prior art：First, data command intelligence cannot be passed through
Crank is controlled to rotate, it is inconvenient for operation；2nd, structure fluctuation of service, sliding block are run on slide bar, due between sliding block and slide bar
There are force of sliding frictions, and the resistance of relative motion between the two is big, and connecting rod push-and-pull sliding block is difficult, and operational process has some setbacks.
How a smooth mechanism is designed, and structure novel, push-and-pull sliding block is light, and operation is smooth, passes through data command
Crank is controlled to rotate, automatic demonstrating crank block apparatus for demonstrating transmission process, structural stability is high, and service life is long, this is anxious
It need to solve the problems, such as.
The content of the invention
The defects of present invention is in order to overcome the prior art discloses a kind of smooth mechanism.
It is an object of the present invention to design a kind of smooth mechanism, there is rolling in structure novel between sliding block and slide bar
Kinetic force of friction, the resistance of relative motion between the two is small, and operational process is smooth, by data command leading screw is controlled to rotate, automatically
Crank block apparatus for demonstrating transmission process is demonstrated, structural stability is high, and service life is long.
In order to realize these purposes and further advantage according to the present invention, a kind of smooth mechanism is provided, including：
Slider-crank mechanism, with crank, connecting rod, sliding block, linear bearing and slide bar, the linear bearing sliding sleeve is in slide bar
On, linear bearing is fixed in sliding block, articulated linkage one end on sliding block, and the connecting rod other end is hinged crank one end, and crank is another
One end is in linkage with electric machine main shaft；
Motor is used for as crank powered rotation, described crank one end and electric machine main shaft linkage；
Host computer is used to generate motor power break-make and converts the control instruction of current direction in motor；
PLC is used to receive host computer motor power break-make and converts the control instruction of current direction in motor, and makes corresponding
Action, control motor power break-make and conversion motor in current direction；
Power supply provides electric energy for above-mentioned each electric elements.
Preferably, the linear bearing adaptation is placed in sliding block.
Preferably, the linear bearing periphery is connected by welding with sliding block inside.
Preferably, the crank is vertical with electric machine main shaft, and crank is sleeved on electric machine main shaft.
Preferably, the electric machine main shaft is interference fitted with crank.
Preferably, the electric machine main shaft drive connection driving gear, driving gear and driven gear engaged transmission, it is driven
Vertical fixed crank in the shaft of gear.
Preferably, the motor is decelerating motor.
The present invention includes at least following advantageous effect：Since host computer generates electric current in motor power break-make and conversion motor
The control instruction in direction, PLC receives host computer motor power break-make and converts the control instruction of current direction in motor, and makes
Current direction in corresponding action, control motor power break-make and conversion motor, therefore the data command intelligence for passing through host computer
Crank is controlled to rotate, structure novel, easy to operate, good demonstration effect meet prolonged Xun Huan demonstration；Since linear bearing is slided
Dynamic to be sleeved on slide bar, linear bearing is fixed in sliding block, therefore structure novel, and there are rolling friction between sliding block and slide bar
Power, the resistance of relative motion between the two is small, and operational process is smooth.
Part is illustrated to embody by further advantage, target and the feature of the present invention by following, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
