Abstract
The utility model discloses a dual drive automatic vibration amplitude modulation vibrating device, it mainly comprises bi-motor (1), amplitude modulation case and vibration case, and the amplitude modulation case comprises box and two bevel gear axle (3) of setting in it and rather than a set of amplitude modulation gear (4) of meshing, and the one end of these two bevel gear axle (3) is by a motor drive respectively, and the other end is connected with the input shaft of vibration case, and the vibration case comprises box and the multiunit axle (7) of setting in it and setting at epaxial coupling eccentric block (8) of every group and activity eccentric block (9). The utility model has the advantages of reasonable design, because the amplitude modulation part does not participate in the vibration, therefore improved the reliability and the life of equipment, and it can take the multiaxis, shake case simultaneous working more, the high-power vibration of specially adapted.
Description
The utility model belongs to the mechanical oscillation technical field, and what relate generally to is a kind of two vibration amplitude modulated oscillations device automatically that drives.
At present, vibrate desk-top vibrating forming machine owing to be that the eccentric full square of band starts, thereby starting power is big, the time is long, and by the system resonance district time, can produces resonance, system architecture intensity is had considerable influence.And in large-scale material forming process, often need to feed in raw material with the little force vibration that shakes earlier, it is closely knit to shake by force with large amplitude again, and existing vibratory equipment is difficult to meet the demands.Existing several amplitude modulated oscillations all is amplitude modulation in vibrating bin, and not only amplitude modulation mechanism participates in vibration, and does not fit into powerful vibrating device.
The purpose of this utility model namely produces thus, proposes a kind of Dual-motors Driving, the outer amplitude modulation of vibrating bin, simultaneously with two automatic vibration amplitude-modulated vibration equipments that drive of multiaxis, the work of many vibrating bins.Use this pair driving to vibrate the amplitude modulated oscillations device automatically and can realize that zero amplitude starts, got rid of the interference of resonance region, and in vibration processes, arbitrarily change the vibration force size, realize many amplitude vibrations.
For achieving the above object, the utility model is achieved through the following technical solutions: it mainly is made up of amplitude modulation case and vibrating bin, the amplitude modulation case is by casing and be arranged on two helical gear shafts in the casing and form with one group of amplitude modulation gear of its engagement, one end of these two helical gear shafts is respectively by a motor-driven, and the other end connects by the power shaft of universal interlink and vibrating bin; Vibrating bin by casing, be arranged on the many groups axle in the casing and the shaft coupling eccentric block and the movable eccentric block that are arranged on every group of axle form, wherein many group axles add up to even numbers, the shaft coupling eccentric block on each even number axle all with adjacent odd number axle on movable eccentric block mesh by gear; Shaft coupling eccentric block on each odd number axle all with adjacent even number axle on movable eccentric block mesh by gear.
The utility model reasonable in design is not because its amplitude modulation part participates in vibration thereby reliability and the service life that can improve equipment outside vibrating bin.Because the number of axle amount in the vibrating bin can be any even number, and is with eccentric block on each axle, can make like this eccentric force respectively by every through-drive, make the holding capacity equilibrium of each axle, improved the reliability of equipment, and fill on each axle eccentric basically identical, reduced the specification of parts.Because it is stepless adjustable that it can make vibration amplitude be in open state easily, thereby various line style technologies are controlled easily.Simultaneously, eliminate the excessively resonance region covibration in the common shake table startup-shutdown process, improved structural strength.Owing to can avoid the motor frequent starting of start-stop vibration, realize that one-shot repeatedly uses by amplitude modulation, make frequent starting reduce to minimum to the impact of circuit.And it can be with multiaxis, the work of many casees simultaneously, is specially adapted to high-power vibration.
The utility model has following accompanying drawing:
Accompanying drawing 1 is the utility model amplitude modulation box structure schematic diagram.
Accompanying drawing 2 is the utility model vibrating bin structural representation.
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1, 2: present embodiment mainly is made up of bi-motor, amplitude modulation case and vibrating bin, the amplitude modulation case is made up of amplitude modulation casing 2 and two helical gear shafts 3 and one group of amplitude modulation gear 4 of being arranged in this casing, amplitude modulation gear 4 meshes with two helical gear shafts 3 respectively, each is driven one end of these two helical gear shafts by a motor 1, and the other end connects with the power shaft of vibrating bin by universal interlink 5.Vibrating bin is by vibration box body 6 and be arranged on the many groups axle 7 in this casing and the shaft coupling eccentric block 8 and the movable eccentric block 9 that are arranged on every group of axle form, wherein organize the even numbers that add up to of axles more, present embodiment is four groups of a, b, c, d, movable eccentric block 9 on the connecting shaft eccentric block 8 of a, c-axis and b, the d axle passes through gear mesh, and is driven by a axle; Equally, the movable eccentric block 9 on the shaft coupling eccentric block 8 on b, the d axle and a, the d axle meshes by gear, and is driven by the d axle.Also can be connected with the power shaft of another vibrating bin by universal interlink by a, d axle, so can be with simultaneously the work of many vibrating bins, be specially adapted to high-power vibration.The course of work of present embodiment is as follows: bi-motor is controlled two power transmission shaft relative rotations and is made it synchronous by the amplitude modulation case, drive the one or more vibrating bin work that connect with it, because the relative rotation of two driving shafts changes relative eccentric moment is changed arbitrarily to maximum from zero, thereby changed total eccentric moment, reached the purpose of amplitude modulated oscillations.
