In the oscillator in the related art, when three eccentric shafts are adopted to realize rotary vibration, one of the eccentric shafts is used as a driving shaft to drive the other two eccentric shafts to rotate, so that the oscillating effect is achieved. Since the oscillator is driven by one shaft to drive two shafts, a balancing weight is needed to be added at the driving shaft. And the balancing weight is added at the position of the single eccentric driving shaft, so that a space is reserved for the rotation of the balancing weight additionally, and parts such as a chassis are additionally arranged due to the requirement of stabilizing an oscillator. When the oscillator runs, the balancing weight does not rotate in the geometric center, so that the driving shaft is required to bear radial pressure, and meanwhile, the driving shaft is required to bear pressure in the horizontal direction generated when the balancing weight rotates, and the driving shaft has high strength requirements. Therefore, the rotation speed of the oscillator cannot be too high, the load cannot be too high, and otherwise the centrifugal force generated by the balancing weight is too high, so that the service life of the driving shaft and the service life of the oscillator are influenced. For experiments with a large number of oscillation requirements, such oscillators are difficult to meet and cannot oscillate for a long period of time.

To the above-mentioned problem, the embodiment of the application provides an oscillation device and experimental facilities, can promote the running stability of oscillation device when high-speed and long-time oscillation, can satisfy the experiment that has high-speed, heavy load and long-time oscillation demand.

The following describes the technical scheme of the embodiments of the present application in detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of an oscillation device shown in an embodiment of the present application; fig. 2 is a schematic installation view of a rotating member of the oscillating device shown in fig. 1.

Referring to fig. 1 and 2, the oscillating device provided in the present application includes a base plate 110 and three rotating members 111 rotatably mounted to the base plate 110; the upper side of the bottom plate 110 is provided with a supporting plate 130, the lower side is provided with a balancing weight 120, and two ends of the rotating piece 111 are respectively positioned on the upper side and the lower side of the bottom plate 110 and are respectively fixedly connected with the supporting plate 130 and the balancing weight 120 through eccentric structures; the three rotating members 111 are located at three vertexes of the virtual triangle, and an output shaft 141 of the driving device is perpendicular to the virtual triangle and is in transmission connection with the three rotating members 111, so as to drive the three rotating members 111 to rotate synchronously. When the oscillating device of the embodiment operates, the three rotating members 111 can drive the supporting plate 130 to oscillate, and the balancing weights 120 are arranged at the bottoms of the three rotating members 111 and fixedly connected with the three rotating members 111 through the eccentric structures, so that centrifugal force generated by the balancing weights 120 can be shared by the three rotating members 111, not only can load larger oscillating load, but also the operation stability of the oscillating device during high-speed and long-time oscillation is improved, and experiments with high-speed, heavy-load and long-time oscillation requirements can be met.

Compared with the scheme that the balancing weight is connected with only one rotating piece in the existing oscillator, the balancing weight 120 is connected with three rotating pieces 111 simultaneously, is more stable in installation, can bear larger load and rotating speed, reduces the strength requirement on the rotating pieces 111, and cannot easily cause physical fatigue (deformation) of the rotating pieces to influence the service life of the whole oscillating device in the oscillating working process, so that the stability of the whole oscillating device is better, and the whole oscillating device can work continuously for a long time.

Fig. 3 is a schematic perspective view of the rotating member 111 of the oscillating device shown in fig. 1; fig. 4 is a side view of the rotation member 111 of the oscillation device shown in fig. 1.

Referring to fig. 1 to 4, in some embodiments, the rotating member 111 includes a shaft body 1110, two ends of the shaft body 1110 are respectively provided with a first eccentric connecting shaft 1111 and a second eccentric connecting shaft 1112, the rotating member 111 is connected to the supporting plate 130 through the first eccentric connecting shaft 1111, and is connected to the balancing weight 120 through the second eccentric connecting shaft 1112; the axes of the first eccentric connecting shaft 1111 and the second eccentric connecting shaft 1112 are parallel to the axis of the shaft body 1110 and are located on two radial sides of the shaft body 1110.

In some embodiments, the first eccentric connecting shaft 1111 of the rotating member 111 is connected to the supporting plate 130 through the upper bearing housing 131, and the second eccentric connecting shaft 1112 is connected to the balancing weight 120 through the lower bearing housing 122. The driving device can drive the three rotating members 111 to rotate, and when the three rotating members 111 rotate, the upper supporting plate 130 can be driven to move through the first eccentric connecting shaft 1111, and meanwhile, the lower balancing weight 120 can be driven to move through the second eccentric connecting shaft 1112. Because the first eccentric connecting shaft 1111 and the second eccentric connecting shaft 1112 are respectively located at two radial sides of the shaft body 1110 of the rotating member 111, when the movement directions of the supporting plate 130 and the balancing weight 120 are opposite, the balancing weight 120 can buffer the centrifugal force generated by the supporting plate 130, and meanwhile, the supporting plate 130 can buffer the centrifugal force generated by the balancing weight 120, so that the running stability of the oscillating device is improved, the requirement of high-speed oscillation can be met, for example, the maximum movement of the supporting plate 130 can reach 1200 rpm; the requirement of long-time oscillation can be met, for example, an oscillation experiment can be carried out for 48 hours; but also to withstand larger oscillating loads, for example up to 2kg.

In some embodiments, since the rotating member 111 needs to bear axial force and radial force, the first eccentric connecting shaft 1111 and the second eccentric connecting shaft 1112 may be integrally formed to secure the strength of the rotating member 111, which may improve the overall structural strength of the rotating member 111. In some embodiments, the rotating member 111 is made of a relatively strong metal material, such as, but not limited to, 303 stainless steel.

In this embodiment, when the rotating member 111 drives the balancing weight 120 to rotate, the balancing weight 120 generates centrifugal force. The faster the rotation speed, the greater the centrifugal force generated, and the greater the radial force of the weight 120 acting on the rotating member 111. In this embodiment, since the three rotating members 111 are all connected to the weight 120 and buffered by the connection of the lower bearing seat 122, the radial force of the weight 120 on the rotating members 111 is reduced, and the service life of the rotating members 111 is prolonged.

The driving device may include a motor 140, an output shaft 141 of the motor 140 is provided with a driving wheel 1411, three rotating members 111 are respectively provided with driven wheels 1114, the output shaft 141 of the motor 140 is in transmission connection with the three rotating members 111 through a flexible transmission member 150, and the flexible transmission member 150 is wound between the driving wheel 1411 and the three driven wheels 1114. The flexible transmission member 150 includes a double-sided toothed synchronous belt, and when the driving wheel 1411 rotates, three driven wheels 1114 can be driven to synchronously rotate by the double-sided toothed synchronous belt. By using synchronous belt transmission, noise generated in the oscillating process is reduced, phase errors generated in the processing and assembling processes of the three rotating parts 111 can be reduced, and the running precision of the oscillating device is ensured.

In this embodiment, the three rotating members 111 have the same structure, the virtual triangle is an isosceles triangle, the output shaft 141 is disposed through the center of gravity of the virtual triangle, so that when the driving wheel 1411 rotates each time, the number of teeth of the double-sided toothed synchronous belt corresponding to each side of the virtual triangle is the same, so that the oscillating device reduces shaking during operation, and has higher stability. In addition, compared with the related art, the reserved space for the rotation of the balancing weight 120 is reduced, and components such as a chassis for stabilizing the oscillating device can be omitted. The space is saved, the cost is reduced, the overall weight of the oscillating device is reduced, the volume is smaller, a plurality of oscillating devices can be placed on a test bed with the same area, and different oscillating experiments can be conveniently carried out at the same time. In addition, by adopting the above structure, the eccentric oscillation of the supporting plate 130 and the substances carried by the supporting plate and the eccentric oscillation of the balancing weight 120 can be offset, so that the stability of the oscillating device is improved.

In some embodiments, the eccentricity of the rotating member 111 is the same, that is, the distance from the axis of the shaft body 1110 of the rotating member 111 to the axis of the first eccentric connecting shaft 1111 of the rotating member 111 is equal to the distance from the axis of the second eccentric connecting shaft 1112 of the rotating member 111, so that the amplitude of the supporting plate 130 and the balancing weight 120 is the same, for example, the eccentricity may be 2.5 mm, and the amplitude may be 5 mm. This can further improve the stability of the oscillation device.

In some embodiments, when the three rotation members 111 are installed, the phases of the three rotation members 111 may be made uniform, so that the three rotation members 111 can be ensured to rotate synchronously, thereby improving the stability of the oscillation device.

By adopting the above structure, when the oscillating device works, the supporting plate 130 and the substances carried by the supporting plate can generate horizontal force, the balancing weights 120 can generate opposite force, and the opposite forces can offset each other, so that the stability of the whole oscillating device in the rotation process is realized.

In some embodiments, the drive means is movably disposed relative to the base plate 110; a tension adjusting mechanism is arranged between the motor 140 and the bottom plate 110, and the tension adjusting mechanism is used for adjusting the relative positions between the driving wheel 1411 and the three driven wheels 1114 so as to adjust the tension of the flexible transmission member 150, so that the flexible transmission member 150 can be prevented from loosening after long-time operation.

In some embodiments, motor 140 is fixed to mounting plate 142, and mounting plate 142 is movably disposed with respect to base plate 110; the tension adjusting mechanism includes an adjusting fixing block fixed to the base plate 110, a tension adjusting block 143 fixed to the mounting plate 142, and a screw adjuster connected between the adjusting fixing block and the tension adjusting block 143. An adjustment fixing block and a tension adjusting block 143 may be provided at the bottom of the base plate 110 and located at one side of the motor 140.

The screw adjusting member may be a screw connected between the adjusting fixing block and the tensioning force adjusting block 143, and when the screw is rotated, the adjusting fixing block and the tensioning force adjusting block 143 can generate relative movement, so that the motor 140 and the base plate 110 generate relative movement, and the distance between the driving wheel 1411 and the three driven wheels 1114 is slightly changed, thereby achieving the purpose of adjusting the tensioning force of the flexible transmission member 150. The tension adjusting mechanism can also stabilize the motor 140, and can prevent the output shaft 141 of the motor 140 from being biased by the tension of the synchronous belt.

In some embodiments, the middle part of the bottom plate 110 may be provided with a first hollow part 112, and the middle part of the balancing weight 120 may be provided with a second hollow part 121; the first hollow portion 112 and the second hollow portion 121 are vertically opposite, the motor 140 comprises a main body connected with the output shaft 141, the output shaft 141 is arranged in the first hollow portion 112 in a penetrating mode, and the main body is arranged in the second hollow portion 121 in a penetrating mode, so that the structure of the oscillating device is more compact, space occupation can be reduced, and weight of the oscillating device can be reduced.

In some embodiments, the oscillating device is further provided with a switch member 113 for defining a rotation position of the rotation member 111, the switch member 113 may be mounted on an upper side of the base plate 110, and a limit member 1113 in limit fit with the switch member 113 may be disposed on the shaft body 1110 of the rotation member 111, so that after the oscillating device is completed, the support plate 130 may be stopped at a specific position or the limit member 1113 of the rotation member 111 may be stopped at a specific position. The switching part 113 may include a photoelectric switch, but is not limited thereto. In addition, the stopper 1113 also serves to balance the rotation member 111, because the rotation member 111 is installed in a position lower than the bottom plate 110 and longer than the position upper than the bottom plate 110, so that the weight of the upper and lower parts is not uniform, and the rotation is easy to shake. And the limiting piece 1113 is added on the upper side of the rotating piece 111, so that the weight of the upper part and the lower part of the rotating piece 111 can be balanced, and the rotating piece 111 can be ensured to be more stable in rotation.
