Embodiment 1
[0017] refer to Figure 1-2 , a composite motor shock-absorbing pedestal, comprising a base 1, the upper end surface of the base 1 is provided with a placement groove 2, and the inner wall of the placement groove 2 is symmetrically provided with a plurality of limiting grooves 3, and the corresponding plurality of limiting grooves The load-bearing plate 4 and the movable plate 5 are slidably connected in 3, and the load-bearing plate 4 is located above the movable plate 5. The load-bearing plate 4 is used to place the working equipment. Spring 6, and the upper and lower ends of a plurality of damping springs 6 are respectively fixedly connected to the lower end surface of the bearing plate 4 and the upper end surface of the movable plate 5, and an elastic airbag is elastically connected between the lower end surface of the movable plate 5 and the bottom groove wall of the placement groove 2 8, and the elastic airbag 8 is filled with magnetorheological fluid (magnetorheological...
Embodiment 2
[0022] refer to image 3 The difference between this implementation and Embodiment 1 is that: the lower end surface of the movable plate 5 is provided with a permanent magnet plate 15, and the magnetic pole of the side opposite to the electromagnet 7 of the permanent magnet plate 15 is the same.
[0023] When the magnetic field intensity of the electromagnet 7 changed, the magnetic repulsion between the electromagnet 7 and the permanent magnet plate 15 also changed, and then the compressive force that the shock absorbing spring 6 was subjected to also changed, and then the shock absorbing spring 6, The characteristics of the shock absorber composed of the movable plate 5, the elastic air bag 8 and the magnetorheological fluid can be changed more obviously. For some working equipment with a larger vibration amplitude, the shock absorber effect is more obvious, thereby improving the applicability of the device. sex.
