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 to connecing for sliding block and slide bar
Contacting surface is big, and frictional force between the two is also big, and connecting rod push-and-pull sliding block is difficult, and operational process has some setbacks.
How a crank driving mechanism is designed, and structure novel, push-and-pull sliding block is light, and operation is smooth, passes through data
Instruction control crank rotates, and automatic demonstrating crank driving mechanism 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 crank driving mechanism.
It is an object of the present invention to a kind of crank driving mechanism is designed, and structure novel, contact of the sliding block with slide bar
Face is small, and force of sliding friction between the two is also small, and connecting rod push-and-pull sliding block is easy, and operational process is smooth, is controlled by data command
Leading screw rotates, automatic demonstrating crank driving mechanism transmission process, and 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 crank driving mechanism is provided, including：
Slider-crank mechanism, with crank, connecting rod, sliding block and slide bar, the sliding block sliding sleeve is hinged on sliding block on slide bar
Connecting rod one end, the connecting rod other end are hinged crank one end, and the crank other 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, protrusion is equipped on the medial surface being in contact in the slide bar with sliding block.
Preferably, each protrusion on the sliding block medial surface is triangular in shape or arc-shaped.
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；Due in slide bar and cunning
The medial surface that block is in contact is equipped with protrusion, therefore structure novel, and the contact surface of sliding block and slide bar is small, frictional force between the two
Also small, connecting rod push-and-pull sliding block is light, 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.
