In the utility model, main shaft is arranged on the bearing support, and bearing support is fixed on the lower panel.
The utility model is provided with U type groove on the top of lower pendulum bar, lower pendulum bar is connected with short connecting rod by the fixing bolt in the U type groove.The adjusting that swing axis swings back and forth several angle can realize by the position of U type groove up-down adjustment linkage connector.
Be provided with the adjusting nut that is used for regulating short connecting rod length in the joint of lower pendulum bar and short connecting rod.Be provided with the adjusting nut that is used for regulating long connecting rod length in the joint of swing axis and long connecting rod.Long connecting rod and short connecting rod and the linkage connector at two ends all are by being threaded, can the free adjustment long connecting rod and the length of short connecting rod by adjusting nut, use nut check again after position regulation is good, and can realize the swing back and forth adjusting of several angle of swing axis equally.
The bottom of swing axis is fixed in the above by the swing axis bearing on the plate.The swing axis end can be connected with long connecting rod by pole.
During the utility model work, main shaft drives the cam rotation, roller moves along cam path, and the drive lower pendulum bar is swung around the rotatingshaft in the base, the swing of lower pendulum bar drives the upper pendulum bar swing by short connecting rod, the swing of upper pendulum bar drives swing axis and swings back and forth by long connecting rod, pole again, thereby has realized the swing requirement of swing axis.
This mechanism adopts upper and lower double pendulum bar structure, mainly be the needs for the stability in the high speed operation process, some machine swings require to reach 300～500 times/minute, must have very high stability, adopt double-lever mechanism stability better, and regulate convenient.
The swing back and forth adjusting of several angle of swing axis, mainly pass through dual mode: a kind of is position by the U type groove up-down adjustment linkage connector in the lower pendulum bar; To be long connecting rod and short connecting rod be by being threaded with the linkage connector at two ends another kind, can free adjustment length, use nut check again after position regulation is good.By the careful adjusting of above dual mode, can make the swing axis pendulum angle more accurate, various angles require all can realize in certain hunting range.
Compared with prior art, the utility model can be realized several angle scope swing requirement, and machine construction is compacter, the operation is more reliable.
