Abstract
The invention relates to the field of intermittent power mechanisms, and discloses an intermittent linear power mechanism for pushing a cam to move by a roller, which comprises a driving shaft, a turntable, rollers and a cam, wherein the driving shaft is provided with the turntable; the free end of the cam is connected with the upper end of a turnbuckle, the lower end of the turnbuckle is connected with the front section of a rocker, the front end of the rocker is mounted on the supporting shaft, the rear end of the rocker is lapped above a sliding block, the sliding block is connected with the lower end of a spring, and the upper end of the spring is fixed on a third rack. The invention solves the problem that the cam type intermittent mechanism in the prior art can not directly provide linear power for the actuating mechanism under the condition of a long distance.
Description
Technical field
Present invention relates particularly to intermittent power field of mechanisms, relate more specifically to a kind of be moved by roller urges cam
Intermittent straight line actuating unit.
Background technology
Traditional Cam intermittent mechanism is several rollings being distributed in by the circular motion promotion of cam on turntable
Son, so that the mechanism of intermittent rotation occurs for turntable, this indexing mechanism is difficult to the executive item that interval moves along a straight line（Than
Dibbler in such as smart bunch planting kind）Power is directly provided.When executing agency and power source are apart from each other, using traditional convex
Wheeled indexing mechanism is as power, it is necessary to which a series of additional transmission mechanisms, certainly will cause unnecessary energy loss, traditional is convex
Making, the assembly precision requirement of wheeled indexing mechanism are general all higher, and clean environment degree also there are certain requirements, therefore cost phase
To higher, some special occasions are applied in general to.So design it is a kind of it is of simple structure and low cost, can be straight under relatively long distance
It is connected in executing agency and provides straight line power and suitable for the indexing mechanism of common occasion, there is important use value and promotion price
Value.
The content of the invention
It can not directly be provided to solve Cam intermittent mechanism in the prior art in relatively long distance for executing agency
The problem of straight line power, the present invention provide a kind of intermittent straight line actuating unit moved by roller urges cam.
The present invention adopts the following technical scheme that：A kind of intermittent straight line actuating unit moved by roller urges cam, institute
Stating actuating unit includes driving shaft, turntable, roller, cam, is equipped with turntable on driving shaft, several rollings are evenly distributed on turntable
Son sets driven shaft above turntable, is equipped with cam on driven shaft, during dial movement, roller interval and cam contact；It is convex
Wheel free end is connected with turnbuckle upper end, and the turnbuckle lower end is connected with rocking bar leading portion, and rocker front end is mounted on supporting
On axis, rear end is overlapped on above sliding block, which is connected with lower spring end, and spring upper end is fixed in the 3rd rack.
The present invention is moved conventional cam roller mechanism reverse utilization by roller urges cam, then coordinate rocker device,
Realize remote Linear transmission；Several rollers are circumferentially distributed in the side of disk-shaped part, these rollers promote cam successively,
Achieve that intermittently-driving；The swing of cam is transmitted to by rocking bar using turnbuckle, it is possible to by the position for adjusting turnbuckle
It puts and length, to preset cam initial position, rocking bar initial position and torque conversion proportion.

Symbol description
1. 8. rocking bar of the first rack 2. roller, 3. turntable, 4. bolt, 5. cam, 6. driven shaft, 7. turnbuckle, 9. spring
10. the 3rd rack of 11. guide rail of sliding block, 12. support shaft, 13. 14. second rack 15 of driving shaft.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
Referring to the drawings, the present invention provides a kind of intermittent straight line actuating unit moved by roller urges cam, the first machine
Driving shaft 13 is fixed on frame 1, turntable 3 is installed on driving shaft 13, is evenly distributed several rollers 2 on turntable 3, on turntable 3
Driven shaft 6 is fixed in second rack 14 of side, cam 5,5 free end of cam and 7 upper end of turnbuckle are installed on driven shaft 6
Connection, 7 lower end of turnbuckle are connected with 8 leading portion of rocking bar, and 8 front end of rocking bar is mounted in support shaft 12, and rear end is overlapped on cunning
10 top of block, the sliding block 10 are connected with 9 lower end of spring.Sliding block 10 is in guide rail 11, and guide rail 11 is fixed in rack 1.Spring 9
Lower end is fixed on 10 top of sliding block, and upper end is fixed in the 3rd rack 15, the rotor number preferably 10.
3 edge of turntable is vertically threaded hole, and bolt 4 is equipped in threaded hole, and 4 middle part of bolt is set with roller
2.Sliding block 10 is in guide rail 11.
In a preferred embodiment, 5 free end of cam is connected by hinge with 7 upper end of turnbuckle, the flower
Blue 7 lower end of screw is connected by hinge with 8 leading portion of rocking bar.
The course of work：
1st, perform：Driving driving shaft 13 counterclockwise, turntable 3 rotates counterclockwise therewith, when roller 2 turns to 5 side of cam with turntable 3
After edge, just cam 5 is promoted forward.Then, cam 5 is rotated clockwise around driven shaft 6.Since 5 free end of cam is by spending orchid
Screw 7 is connected with rocking bar 8, and then rocking bar 8 is just rotated clockwise around support shaft 12.At this point, 5 free segment of cam and 8 structure of rocking bar
Into double rocker mechanism.8 rear end of rocking bar imposes sliding block 10 downward pressure, and sliding block 10 overcomes the drawing of spring 9 in track 11
Power is moved downward with certain speed.
2nd, interval：Turntable 3 is rotated further, and roller 2 departs from cam 5, and the pressure for acting on 10 top of sliding block disappears, institute
With under the pulling force effect of spring 9, sliding block 10 returns to original position rapidly upward.When other rollers 2 on turntable 3 turn to successively
During 5 edge of cam, the above process will be reappeared successively.This is the basic principle that the present invention provides intermittent straight line power.
The present invention is moved conventional cam roller mechanism reverse utilization by roller urges cam, then coordinate rocker device,
Achieve that remote Linear transmission；Several rollers are circumferentially distributed in the side of disk-shaped part, these rollers promote successively
Cam, so that it may intermittently-driving is realized, if being separately installed with above-mentioned roller in two sides of disk-shaped part, so that it may while be two
A executing agency provides the intermittent straight line power with certain correlation；The swing of cam is transmitted to using turnbuckle and is shaken
Bar, it is possible to by adjusting position and the length of turnbuckle, turn to preset cam initial position, rocking bar initial position and torque
Change ratio；Using backhaul power of the spring as executive item, it is possible to fully extend the intermittent time, more preferably realize set function.
The present invention changes cam face, and different velocity forms can be provided for executive item, changes rail pattern, can change executive item
Movement locus.Roller can be selected common roller bearing, cheap, be easily changed.
