The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.
See also shown in Figure 1, a kind of vibration absorber 1 that the embodiment of the invention provides, comprise for connecting the upper fixed seat 11 that needs vibration-proof equipment and the lower fixed seat 12 that is used for connecting attachment, upper fixed seat 11 is used for support needs vibration-proof equipment, lower fixed seat 12 is used for vibration absorber 1 is fixed on attachment, upper fixed seat 11 and lower fixed seat 12 are oppositely arranged, and parallel to each other, be installed with spiral helicine metallic cable 13 between upper fixed seat 11 and the lower fixed seat 12, elastic deformation can occur in helical metal rope 13, the axis of helical metal rope 13 is parallel to upper fixed seat 11 and lower fixed seat 12, is about to helical metal rope 13 and laterally places.
When the vibrational energy of horizontal direction (X as shown in Figure 1 is horizontal and Y is vertical) reaches vibration absorber 1, vibration absorber 1 is subdued vibrational energy, is reduced amplitude by the horizontal hunting of helical metal rope 13, makes the extraneous vibration that vibration absorber 1 can the offset by the level of direction; When the vibrational energy of vertical direction (Z direction as shown in Figure 1) reaches vibration absorber 1, helical metal rope 13 is out of shape to subdue vibrational energy, reduces amplitude by the elastic compression diastole of vertical direction, makes vibration absorber 1 can offset the extraneous vibration of vertical direction; Therefore, vibrating device 1 of the present invention can be realized the comprehensive vibrationproof protection to the need vibration-proof equipment.
See also Fig. 1 ~ Fig. 3, in the present embodiment, concrete connected mode between helical metal rope 13 and upper fixed seat 11 and the lower fixed seat 12 is: upper fixed seat 11 is fixedly connected with upper mounted plate 14 towards a side of lower fixed seat 12, the part that helical metal rope 13 closes on upper mounted plate 14 is sheathed on the upper mounted plate 14 and by upper fixed seat 11 and compresses, thereby the top of helical metal rope 13 is fixed; Lower fixed seat 12 is fixedly connected with bottom plate 15 towards a side of upper mounted plate 14, and the part that helical metal rope 13 closes on bottom plate 15 is sheathed on the bottom plate 12 and by lower fixed seat 12 and compresses, thereby the bottom of helical metal rope 13 is fixed.
As illustrated in fig. 1 and 2, further, the side that upper mounted plate 14 closes on upper fixed seat 11 offers some equally spaced upper thread grooves 141, the degree of depth of upper thread groove 141 is less than the diameter of helical metal rope 13, spacing between the upper thread groove 141 equates with the pitch of helical metal rope 13, thereby so that the top of helical metal rope 13 is embedded at thread groove 141 and protrudes from thread groove 141, the projection on 13 tops of helical metal rope is fixed by upper fixed seat 11.Equally, the side that bottom plate 15 closes on lower fixed seat 12 offers some equally spaced lower thread grooves 151, the degree of depth of lower thread groove 151 is less than the diameter of helical metal rope 13, spacing between the lower thread groove 151 equates with the pitch of helical metal rope 13, thereby so that the bottom of helical metal rope 13 is embedded at lower thread groove 151 and protrudes from lower thread groove 151, the projection of the bottom of helical metal rope 13 is fixed by lower fixed seat 12.When vibration absorber 1 is subject to the vibratory impulse of extraneous horizontal direction (directions X as shown in Figure 1 and Y-direction), helical metal rope 13 can produce horizontal hunting, because the upper and lower of helical metal rope 13 is embedded at respectively in thread groove 141 and the lower thread groove 151, helical metal rope 13 is subject to the constraint of thread groove 141 and lower thread groove 151 and can produce excessive torsional deformation, avoided further having guaranteed dependability and the service life of vibration absorber 1 because helical metal rope 13 produces the problem that excessive deformation can't restore to the original state and then cause damaging.
Between upper fixed seat 11 and the upper mounted plate 14 specifically by snap fit 16 connection that is fixedly clamped, between lower fixed seat 12 and the bottom plate 15 specifically by snap fit 17 connection that is fixedly clamped.Certainly, also can be fixedly connected with by conventional fasteners such as screw, rivets between upper fixed seat 11 and the upper mounted plate 14 and between lower fixed seat 12 and the bottom plate 15.
Because can protruding from the outer surface of upper fixed seat 11 and lower fixed seat 12, snap fit 16,17 can affect assembling, in order to overcome this problem, the present invention is by offering respectively platform upper groove 111 and low groove 121 at the outer surface of upper fixed seat 11 and lower fixed seat 12, snap fit 16,17 is contained in respectively in upper groove 111 and the low groove 121, thus be convenient to upper fixed seat 11 and lower fixed seat 12 respectively with need vibration-proof equipment and attachment assembling.
Further, offer some upper installing holes 112 on the upper fixed seat 11, upper fixed seat 11 is fixedly connected with needing vibration-proof equipment by the securing member (not shown) that is arranged in the upper installing hole 112.Equally, offer some lower installing holes 122 on the lower fixed seat 12, fix 12 and be fixedly connected with attachment by the securing member (not shown) that are arranged in the lower installing hole 122 down.This securing member can be the connectors commonly used such as screw, rivet.
In the present embodiment, the 13 preferred bendings of helical metal rope are spiral helicine steel wire rope, and steel wire rope intensity is high, good toughness, more is conducive to improve the vibration resistance of vibration absorber 1.
