Label declaration
Casing 1, the first lever 21, the second levers 22, shift fork 3, hexagon socket head cap screw 31, bearing 32, bearing 4, movable half-clutch device 5, elongated slot 51, groove 52, fixing half-clutch device 6, rotational pin 61, clutch shaft 7, stage clip 8, cam 9.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
As shown in the figure, a kind of coiling machine clutch on-off automatic controls that the present invention discloses, comprises casing 1, lever, L shaped shift fork 3, bearing 4, movable half-clutch device 5, fixing half-clutch device 6, clutch shaft 7, stage clip 8.
Wherein clutch shaft 7 is arranged on the bottom of casing 1, and movable half-clutch device 5 and fixing half-clutch device 6 are all arranged on clutch shaft 7 and are positioned at outside casing 1; On movable half-clutch device 5, offer some elongated slots 51, being arranged on clutch rotational pin 61 on fixing half-clutch device 6 can insert and in elongated slot 51, realize two clutch functions between clutch, wherein there is a ramp structure clutch rotational pin 61 this one end in elongated slot 51, is conducive to clutch rotational pin 61 and inserts more accurately in elongated slot 51; On movable half-clutch device groove 52, process circular arc, when clutch shaft 7 rotates transferring power, with the approximate pure rolling friction of bearing 32, reduced wearing and tearing, improved the life-span.
Lever comprises the first lever 21 and the second lever 22, the first lever 21 and the second lever 22 are all articulated on the interior same level of casing 1 position, the end of the second lever 22 overlaps on first lever 21 the other end, and the other end of the second lever 22 is connected with the cam 9 on motor shaft by the bearing 32 being arranged on bearing 32 pins; The turning point of shift fork 3 is articulated on the bearing 4 being arranged on outside casing 1, and the end of shift fork 3 outside casing 1 is socketed on movable half-clutch device 5; The end of shift fork 3 in casing 1 and the first lever 21 arranged in a crossed manner and be positioned at the first lever 21 above; Cam 9 is arranged on driving shaft and cylindrical comprises the circular arc that twice radius differs, and lifts the second lever 22 shift fork 3 is departed from half-clutch activity device 5 from fixing half-clutch device 6 in the time that driving shaft rotates by circular arc.
