eccentric wheel

14 and 15 rotations of second eccentric wheel, thereby make the different parts of first eccentric wheel 14 and second eccentric wheel 15 alternately replace shake table 16, and make shake table 16 vibrations.

Substrate 11 is square chromium plating steel plates, and this substrate 11 is provided with a motor fixing plate 122, a backing plate 133 and is arranged at interval relative support plate 134 of two on the backing plate 133 and two support arms 162, and it is respectively applied for fixed electrical machinery 12, main shaft 13 and supports shake table 16.The vibration that when working workbench is caused for slowing down vibrating device 10, the downside of substrate 11 is provided with four cushion blocks 111, and the material of this cushion block 111 is the polyurethane of anti-the punching press.

Motor 12 has a machine shaft 121, and to being provided with a through hole 123 in machine shaft 121 places, machine shaft 121 passes this through hole 123 and links to each other with main shaft 13 on the motor fixing plate 122.

Electric cabinet 17 is located on the substrate 11, the rotating speed that this electric cabinet 17 is used to control the keying state of motor 12 and adjusts motor 12.

Main shaft 13 is fixed on the support plate 134 by two bearings 132, and this two bearings 132 is fixed in the outside of two support plates 134, and corresponding bearing 132 places respectively are provided with a perforate (figure does not show) on this two support plate 134, and main shaft 13 passes bearing 132 and this perforate rotation.And an end of this main shaft 13 links to each other with machine shaft 121 by connecting shaft cover 131.

Please consult Fig. 3 and Fig. 4 simultaneously, one first key piece 137 and one second key piece 138 that main shaft 13 is provided with two keyways 135,136 and matches with this two keyway 135,136 respectively.

Offer a keyway 141 that matches with the first key piece 137 on first eccentric wheel 14, this first eccentric wheel 14 is connected on the main shaft 13 by keyway 135, the first key piece 137 and keyway 141 keys, offer a keyway 151 that matches with the second key piece 138 on second eccentric wheel 15, this second eccentric wheel 15 is connected on the main shaft 13 by keyway 136, the second key piece 138 and keyway 151 keys.

Please consult Fig. 5 and Fig. 6 simultaneously, shake table 16 is in the form of annular discs, its lower end is connected with two at interval relative back-up blocks 161, and this shake table 16 is supported in the top of first eccentric wheel 14 and second eccentric wheel 15 by two support arms 162, and contacts with this first eccentric wheel 14 and second eccentric wheel 15.The both sides of being located at main shaft 13 of these two support arms, 162 relative spacings, and these two support arms, 162 inboards respectively are provided with a flange 163, and back-up block 161 promptly is positioned on this flange 163.

For preventing because of high vibration makes shake table 16 over-tiltings, thus stuck between two support arms 162, and two support arms, 162 upper ends respectively are provided with a universal ball 164.And two back-up blocks, 161 two ends of this shake table 16 respectively are provided with a spring 165, and the other end of this spring 165 is connected on the backing plate 133, and shake table 16 broke away from first eccentric wheel 14 and second eccentric wheel 15 when this spring 165 can prevent to vibrate, and made vibration more steady.

When using vibrating device 10 of the present invention, earlier object to be vibrated is fixed on the shake table 16, open motor 12 by electric cabinet 17 again, machine shaft 121 rotations drive main shaft 13 rotations, thereby first eccentric wheel 14 and second eccentric wheel 15 that are connected on the main shaft 13 are rotated.Because the eccentric structure of first eccentric wheel 14 and second eccentric wheel 15 makes the diverse location of the win eccentric wheel 14 and second eccentric wheel 15 alternately replace shake table 16, thereby make shake table 16 vibrations.In the vibration processes, can change the rotating speed of motor 12, thereby change the vibration frequency of shake table 16 by electric cabinet 17.
