Scrap.
Utility model content
To solve the defect that prior art is present, the purpose of this utility model is to provide a kind of adjustable frictional force conveying roller
Road, when workpiece is kept off, drive link stalling, it is ensured that workpiece is not damaged by.
The technical solution of the utility model is：A kind of adjustable frictional force rollgang, including be connected with holder pivots
Transmission shaft lever, support is located at transmission shaft lever two ends, and support is run through in transmission shaft lever one end, and the end run through is fixedly connected with sleeve, covers
Cylinder periphery is arranged sprocket wheel, and sprocket wheel both sides are fitted the end stone and spline pad of sleeve respectively, and the spline pad is consolidated with sleeve
Fixed connection, spline pad connecting spring, the spring-compressed is in the spring retention intracavitary of stent side portion, spring connection regulation spiral shell
Mother, the adjusting nut is connected with bush whorl, and the sprocket wheel connects chain, chain connection driver element.
The transmission shaft lever is provided with some rollers.
The transmission shaft lever is rotated by bearing with support and is connected.
The spline pad is fixedly connected by spline with sleeve.
The sprocket wheel is to be brought into close contact pad between two, two sprocket wheels.
The spring is butterfly spring.
The beneficial effects of the utility model are：Acted on by the elastic force of spring, make the end stone of spline pad and sleeve
It is brought into close contact with sprocket wheel, by the frictional force between them, there is provided the driving force of drive link, after workpiece is blocked stopping, work
Resistance produced by the contact jaw of part and roller-way, overcomes the driving force of drive link, drive link is stopped operating, and makes workpiece and biography
Lever geo-stationary, it is to avoid destruction of the drive rod rotation friction to workpiece surface.
Brief description of the drawings
The utility model has the width of accompanying drawing 3.
Fig. 1 is the utility model stereogram；
Fig. 2 is the utility model sectional side view；
Fig. 3 is the utility model partial enlarged drawing.
Reference is as follows in figure：1st, support, 2, transmission shaft lever, 3, roller, 4, bearing, 5, sleeve, 6, spline pad, 7,
Sprocket wheel, 8, spring, 9, adjusting nut, 10, chain, 11, driver element.
Embodiment
1-3 is described further to the utility model below in conjunction with the accompanying drawings：
A kind of adjustable frictional force rollgang, including the transmission shaft lever 2 being connected is rotated with support 1, support 1 is located at transmission
Support 1 is run through in the two ends of axostylus axostyle 2, one end of transmission shaft lever 2, and the end run through is fixedly connected with sleeve 5, and the periphery of sleeve 5 is arranged sprocket wheel 7,
The both sides of sprocket wheel 7 are fitted the end stone and spline pad 6 of sleeve 5 respectively, and the spline pad 6 is fixedly connected with sleeve 5, spline
The connecting spring 8 of pad 6, the spring 8 is compressed in the spring retention intracavitary of the sidepiece of support 1, and the connection adjusting nut 9 of spring 8 is described
Adjusting nut 9 is threadedly coupled with sleeve 5, and the sprocket wheel 7 connects chain 10, the connection driver element 11 of chain 10.
The transmission shaft lever 2 is provided with some rollers 3.
The transmission shaft lever 2 is rotated by bearing 4 with support 1 and is connected.
The spline pad 6 is fixedly connected by spline with sleeve 5.
The sprocket wheel 7 is to be brought into close contact spacing washer between two, two sprocket wheels 7.
The spring 8 is butterfly spring.
The driver element 11 includes motor.
Before roller-way work, first according to workpiece weight, frictional resistance F produced when workpiece is contacted with roller 3 is calculated
Size, according to Resistance Value F, adjusts precession or the back-out amount of adjusting nut 9, and then adjusts the decrement of butterfly spring, passes through
The maximum that the end stone of the elastic force of change butterfly spring, change sprocket wheel 7 and spline pad 6 and sleeve 5 can be generated is rubbed
Wipe power, make the frictional force can for transmission shaft lever 2 provide driving force while, when meet obstructions F when, will not continue to drive be driven
Axostylus axostyle 2 is rotated.
Locate the elastic force effect produced by the butterfly spring of compressive state, distinguish the end stone of spline pad 6 and sleeve 5
Be close to the both sides of sprocket wheel 7, after motor starts, rotated by chain drive sprocket wheel 7, sprocket wheel 7 and spline pad 6, sleeve 5 it
Between produce frictional force, frictional force drives spline pad 6, sleeve 5 to rotate, and then transmission shaft lever 2 is rotated, and transmission shaft lever 2 passes through rolling
Son 3 drives workpiece to be conveyed along rollgang, when workpiece can not be continued to move to by gear, with spline pad in the rotation process of sprocket wheel 7
6th, the frictional force produced between sleeve 5 is not enough to overcome the resistance between roller 3 and workpiece, stops roller 3, transmission shaft lever 2
Rotate, it is to avoid the abrasion of workpiece surface, i.e. do not stop in driver element, in the case that sprocket wheel 7 is still rotated, the biography on roller-way
Moving axis bar 2 can be stalled, and protect the work piece interface conveyed on roller-way not to be destroyed, the flatness of the contact surface of workpiece and bright and clean
Degree is guaranteed, it is to avoid workpiece scraps the loss caused.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification can also be made, these change
Enter and protection domain of the present utility model is also should be regarded as with modification.
