Description
Technical field
The present invention relates to the transmission device field with endless flexible element conveying rotary motion, is specially that one kind uses ratchet
Anti-rotation axle steer device not in place and its application method.
Background technology
Now traditional forcing press is substantially to feel with operator oneself to complete the operation of pressure frock, when what is given
After pressure is acted on forcing press, the certain angle of axis of rotation, so as to implement subsequent job.If the pressure provided does not arrive setting
Value, then the rotational angle of rotating shaft is just unable to reach requirement, the operation in the case where pressure is not in place, easily causes defective products, reduces
Production efficiency and finished product rate.
The content of the invention
A kind of the defects of in order to overcome prior art, there is provided course changing control dress simple in construction, easy to use, precise control
Put, the invention discloses a kind of anti-rotation axle steer device not in place and its application method using ratchet.
The present invention reaches goal of the invention by following technical solution：
A kind of anti-rotation axle steer device not in place using ratchet, including forcing press force transmitting link axle, it is characterized in that：Also wrap
The ratchet cover plate, spring blocking plate are included, goes out pin plate extension spring, extension spring button, go out pin cam, ratchet pressing plate, ratchet, ratchet backing pin, ratchet backing pin branch
Frame, reset tension spring are buckled, pin socket, ratchet backing pin rack shaft and rack shaft reduction torsion spring,
The ratchet cover plate, go out pin cam and ratchet pressing plate is all enclosed on outside forcing press force transmitting link axle, the ratchet cover plate and ratchet pressing plate are all
It is fixed on forcing press force transmitting link axle, goes out between pin cam and forcing press force transmitting link axle and coordinate for gap；
The lateral surface of the ratchet cover plate is provided with ratchet, and the ratchet cover plate lateral surface that ratchet is covered is no more than ratchet cover plate excircle
Half, the ratchet cover plate are provided with extension spring button, go out pin cam and are provided with reset tension spring button, the one end for going out pin plate extension spring is buckled in extension spring button
On, the other end for going out pin plate extension spring is buckled in reset tension spring and buckled；
Pin socket is located at the side of forcing press force transmitting link axle, and ratchet backing pin support is located at by ratchet backing pin rack shaft
On pin socket, rack shaft reduction torsion spring is cased with ratchet backing pin rack shaft；
Spring blocking plate is fixed on one end of forcing press force transmitting link axle；
One end of ratchet backing pin is fixed on the side of ratchet backing pin support one end, shape between the adjacent ratchet of ratchet backing pin face
Into ratchet groove in, the top for the ratchet groove groove bottom that the lower edge of ratchet pressing plate is formed between two neighboring ratchet,
The one end for going out edge on pin cam props up the lower edge of ratchet, and the other end for going out edge on pin cam is " L " type groove, goes out pin cam " L " type
The trench bottom of groove one end and the distance of ratchet lower edge are more than the diameter of ratchet backing pin.
The described anti-rotation axle steer device not in place using ratchet, it is characterized in that：Formed between two neighboring ratchet
In ratchet groove, for the angle of two side walls of ratchet groove at 75 °~90 °, the bottom of ratchet groove is not less than spine for radius of curvature
The concaved circular cambered surface of tooth backing pin radius.
The application method of the described anti-rotation axle steer device not in place using ratchet, it is characterized in that：As follows according to
Secondary implementation：
The position of ratchet backing pin after setting forcing press force transmitting link axle pressure rotates forward in place when normal；
When in the ratchet groove formed between ratchet backing pin is embedded in two neighboring ratchet, the stop surface of ratchet is kept off by ratchet
Pin stopped, forcing press force transmitting link axle can not reversed turning and can only rotate forward, forcing press force transmitting link axle rotates forward
When drive the ratchet cover plate and the rotation of ratchet pressing plate synchronous forward, go out pin plate extension spring and pull out that pin cam uses pin cam and the ratchet cover plate is same
Step rotates forward；
When between ratchet backing pin is embedded in two neighboring ratchet in the ratchet groove that is formed, now forcing press force transmitting link axle
Rotate forward, because one end of ratchet backing pin is fixed on ratchet backing pin support, therefore between ratchet backing pin and Ratchet slide face
Make relative slide；If forcing press force transmitting link axle pressure is not less than normal value, each ratchet is slided from ratchet backing pin successively
Go out, until ratchet backing pin is after last ratchet skids off, under the reset force effect that rack shaft reduction torsion spring applies, ratchet
Backing pin support drive ratchet backing pin drop down onto out pin cam on one end of " L " type groove and stopped in by " L " type groove, now spine
Tooth is no longer influenced by the stop of ratchet backing pin, and forcing press force transmitting link axle is by the effect reversed turning of revolution reset force, forcing press biography
The ratchet cover plate and the revolution of ratchet pressing plate synchronous backward are driven during power pitman shaft reversed turning, goes out pin plate extension spring and pull out pin cam to use
Cam and the revolution of ratchet cover plate synchronous backward are sold, ratchet backing pin is skidded off between the other end on edge and ratchet lower edge from going out on pin cam,
Subsequent forcing press force transmitting link axle rotates forward and drives the ratchet cover plate, goes out pin cam and the rotation of ratchet pressing plate synchronous forward again,
Ratchet backing pin is slided between two ratchets in the ratchet groove formed along the sliding surface of first ratchet, completes once anti-pressure
Operation not in place；If forcing press force transmitting link axle pressure is less than normal value, all ratchets can not be all from ratchet backing pin
Skid off, i.e., ratchet backing pin is still embedded in the ratchet groove formed between two neighboring ratchet, and the stop surface of ratchet is by ratchet backing pin
Stopped, the ratchet cover plate, go out pin cam, ratchet pressing plate and forcing press force transmitting link axle all can not reversed turning and positive can only revolve
Turn.
Present invention employs the control of a set of ratchet mechanism, avoids in pressure situation about just fulfiling assignment not in place.This hair
Bright beneficial effect is：It is simple in construction, easy to use, precise control, it is widely portable to all kinds of fields for having pressure, rotating control
Close.
