Five, the specific embodiment
Now with specific embodiment the utility model is described in further details in conjunction with the accompanying drawings:
The utility model relates to a kind of attached shedding motion of air-jet loom, be meant a kind of improvement of the shedding motion to air-jet loom, mainly be unstable at the existing in prior technology motion, can not realize at a high speed, a kind of positive cam opening device rational in infrastructure is provided, refer in particular to opening shaft and be down in working order solid and reliable, manually flat comprehensive instrument by special use under off working state is again movably, can make opening shaft move to the flat position of combining from the operating position, opening shaft 7 is again eccentric simultaneously, manually flat comprehensive instrument by special use rotates opening shaft 7 a little, reaches the contact condition that changes opening arm rotor 5 and conjugate cam 4.
Operation principle is: in the casing 1 of its shedding motion, via a pair of bevel gear driving cam axle 3 rotations that are installed in power transmission shaft 2 and camshaft 3.One group of conjugate cam 4 is installed on camshaft 3, and camshaft 3 and conjugate cam 4 are fastening one, and corresponding with this group conjugate cam 4 is that one group of opening arm 6 is installed on opening shaft 7.Opening shaft 7 and camshaft 3 are not at grade.The different replaceable group conjugate cams 4 that are somebody's turn to do of fabric as requested.The positive rotation of conjugate cam 4 forces opening arm rotor 5 to produce and moves, and is swing (see figure 3) in center thereby make opening arm 6 with opening shaft 7.
Fixing and mobile, the rotational structure principle (seeing Fig. 2, Fig. 4) of opening shaft 7.The both sides of the opening shaft 7 of one group of opening arm 6 are installed, be separately installed with chuck 9, chuck 9 is connected with elastic rocking beam 8 by chuck bearing pin 11, and elastic rocking beam 8 is connected on the two interior parallel brackets of casing 1 by bearing pin 10, and elastic rocking beam 8 is that the center can be swung with bearing pin 10.Simultaneously the two ends of opening shaft 7 place on two parallel brackets in the casing 1, on two parallel brackets in casing 1 track that opening shaft 7 is moved are arranged.It is outer that one end of opening shaft 7 stretches out on the casing 1 parallel bracket, so that the manually flat instrument 12 of combining is installed under the state of shutting down, make opening shaft 7 move or rotate, but opening shaft 7 external parts do not go out casing 1.
The invariant feature of opening shaft 7 is realized by following scheme: because the clamping action of chuck 9 screwings is locked opening shaft 7 and chuck 9 mutually, chuck 9 and elastic rocking beam 8 are connected with two parallel brackets in the casing 1 by chuck bearing pin 11 and bearing pin 10, constitute the two quadric chains inboard of two parallel brackets in casing 1 respectively.Because the center o1 of opening shaft 7 is in the inboard of 8 liang of hole lines of elastic rocking beam, the elastic force of elastic rocking beam 8 makes opening shaft 7 must not move in the operating position, to realize at a high speed.
The move mode of opening shaft 7 is: load onto the flat instrument 12 of combining at opening shaft 7 external parts, firmly change the flat instrument 12 of combining, because the effect chuck 9 of external force is the center swing with chuck bearing pin 11, while chuck 9, chuck bearing pin 11 is the center swing with elastic rocking beam 8 with bearing pin 10, because the track on two parallel brackets in the casing 1 is to the restriction of opening shaft 7, make elastic rocking beam 8 produce strain, two hole sites increase, again owing to the elastic force of external force greater than elastic rocking beam 8, the center o1 of opening shaft 7 crosses 8 liang of hole lines of elastic rocking beam, move thereby reach on the two parallel bracket tracks of opening shaft 7 in casing 1, realize the flat opening arm rotor 5 disengaging conjugate cams 4 of combining or make, according to the different conjugate cams 4 of changing of fabric.
The eccentric nature of opening shaft 7 is: supported center is o1 on two parallel brackets of opening shaft 7 in casing 1, and the center that the opening shaft 7 of one group of opening arm 6 is installed is o2, and center o1 and center o2's is micro-apart from e.After realizing flatly combining, more finishing changing cam, when opening shaft 7 is got back to the operating position owing to manual reason of rotating flat comprehensive instrument 12 effects from putting down comprehensive position, unclamp the screw on the chuck 9, rotate back and forth the flat instrument 12 of combining again a little, center o2 is center swing with center o1, thereby can adjust the gap of 4 of opening arm rotor 5 and conjugate cams exactly, changes its contact condition, reaching optimum efficiency, do not contact vibration, collision and the excessive power that is produced and do not produce interference pressure and cross pine.Screw the screw on the chuck 9, take away the flat instrument 12 of combining on opening shaft 7 external parts.
