The specific embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, 2, the present invention includes bent axle 10, gear wheel eccentric bushing 2 is installed, adjustable side eccentric bushing 5, gear wheel 3, retaining mechanism 1 and self-locking performance worm and gear governor motion; The two ends of bent axle 10 are installed adjustable side eccentric bushing 5 respectively and gear wheel eccentric bushing 2 are installed, and in adjustable side eccentric bushing 5 and the installation gear wheel eccentric bushing 2 planetary gears 6 are set all; Shaft part part setting-up eccentricity cover 2 at bent axle 10 two ends, 5, regulate bent axle 10 like this an off-centre is arranged, be to be used for accessing Variable Eccentricity, regulate eccentric bushing 5 off-centre is arranged, be a fixing off-centre, and gear wheel 3 is by on the key fixed installation eccentric bushing 2 at one end, like this after adjusting bent axle 10 rotates to a certain position, just obtain a temporary transient eccentric throw, this eccentric throw has got up to form an eccentric throw that fixing crank block is temporary transient with the eccentric combination of regulating eccentric bushing 5, just is installed in the center of regulating bent axle 10 necked parts with respect to a temporary transient eccentric throw after being installed in distance between gear wheel 3 centers of regulating eccentric bushing 5 ends and just forming an adjusting.Because eccentric bushing the 2, the 5th, be installed in two ends regulating bent axle 10 respectively, so in order to guarantee that well two eccentric bushings install the synchronism of rotation on the fuselage body, so inside is provided with planetary gears 6.
As shown in Figure 3, planetary gears 6 is by planetary gear, planet carrier, and sun gear, ring gear constitutes, and ring gear is fixed by key and eccentric bushing, and planet carrier is fixed on the bent axle by key, and sun gear is fixed on the bent axle, and planetary gear is installed on three axles of planet carrier.Planet carrier in the planetary gears 6 is fixed on the bent axle 10 through key, and ring gear is fixing through key and eccentric bushing 2,5, and sun gear is fixed on the bent axle 10; This structure mainly is to be used for when gear wheel 3 drives with 2 rotations of its fixing eccentric bushing, allow the synchronous rotation of eccentric bushing on both sides, and, must be concentric, are equivalent to by regulating bent axle 10 and planetary wheeling mechanism 6 is whole the eccentric bushing 2 on both sides, 5 are fixed together, guarantee two eccentric bushings 2,5 rotational synchronization, but the bent axle 10 in the middle of needing just need be fixed together eccentric bushing 2 extensions of dress gear wheel 3 ends to them in operate as normal with the extension of regulating bent axle 10 rotating to pass in the past, allow its synchronous rotation, transmission could be passed to the eccentric bushing 5 of another side like this, as long as regulating bent axle 10 is fixed on the eccentric bushing, the words that not relative eccentric bushing rotates, being fixed on the sun gear of regulating on the bent axle so just can not rotate, naturally guaranteed the synchronous rotation of other end eccentric bushing, and for the external part of eccentric bushing and adjusting bent axle 10 is fixed, so be provided with locking device 1 at an end of eccentric bushing 2.
As shown in Figure 2, gear wheel 3 is fixing through the installation gear wheel eccentric bushing 2 of key and bent axle 10 1 ends; For secured adjusted bent axle and adjusting eccentric bushing 2, bent axle 10 1 ends in eccentric bushing 2 outer ends are provided with locking device 1, and locking device 1 part is fixing through flange and eccentric bushing 2, and another part is fixed on the bent axle 10 through spline; The existing product of locking device 1 for purchasing.
Shown in Fig. 2,4, bent axle 10 1 ends in adjustable side eccentric bushing 5 outer ends are provided with self-locking performance worm and gear governor motion, and self-locking performance worm and gear governor motion is regulated motor by the driving of worm gear seat, worm gear 8, worm screw 7 and worm and gear and formed.Regulate worm and gear 7,8 fixedly realization is earlier the axle head of worm gear 8 and adjusting bent axle 10 to be fixed together by the worm gear seat, worm screw 7 is by being installed on the worm gear seat then, its worm and gear is combined together, and the other end of worm screw 7 is by flange it to be fixed on stretching out on the end face of adjusting eccentric bushing 5, when regulating bent axle 10 positions, in fact whole adjusting motor is along with big eccentric bushing rotates together.Install one and regulate worm-and-wheel gear, be convenient to automatic adjusting, simultaneously worm and gear is designed to have the self-locking effect, like this after regulating, also can play regulating the effect that bent axle 10 and eccentric bushing 5 are fixed together, prevent simultaneously since during punching press since bounce cause regulating the motor reversing and regulate the small deflection vibration of bent axle 10 with respect to eccentric bushing, thereby guarantee in operate as normal, to regulate bent axle and eccentric bushing can well be done as a whole the rotation.
Operation principle of the present invention, at first drive planetary gears 6 China and foreign countries' toothed portions and the disengaging of interior toothed portion by piston body, regulate worm gear 8 by driven by motor then, make angle of bent axle 10 rotations, by locking device 1 locking, just become a new off-centre by the off-centre 2,5 of eccentric bushing and the off-centre of bent axle 10 so then, so just finished the adjusting of one stroke, this adjustment process has the adjusting driven by motor fully, is automatic adjusting therefore.Internal structure is a planetary gear construction 6, also guaranteed two purposes that eccentric bushing rotates synchronously when well having guaranteed degree of regulation, the self-locking performance of regulating worm and gear has guaranteed that well the bent axle 10 that regulates between eccentric bushing 2,5 springing does not take place in work.Guarantee service behaviour.The present invention realizes regulating by following principle, regulates bent axle 10, by locking device 1 locking, connects each eccentric throw so then.
