Abstract
The utility model discloses a rubber washer rubber foot mat, including the callus on the sole body, this internal bolt hole that is equipped with of callus on the sole, bolt hole inner wall are equipped with a plurality of axial circular arc lugs, and the bolt hole inner wall encloses into a deformation chamber with two adjacent circular arc lug sides. This rubber washer rubber foot mat can play certain interference fit when using the bolt fastening, can not make excessive deformation of bolt hole again and destruction.
Description
Technical field
This utility model relates to a kind of callosity, more specifically, it relates to a kind of rubber mat.
Background technology
Rubber mat is typically bolted on the bottom of machine rack, for absorbing the vibrations of machine and playing anti-skidding effect.When callosity is installed, need bottom callosity, penetrate bolt callosity, shank of bolt is made to pass from the upper end of callosity, bolt is threadedly secured in frame, owing to rubber has certain deformability, in order to be able to make callosity more be securely fixed in frame, the bolt hole of callosity upper surface is generally slightly smaller than the diameter of bolt, owing to shank of bolt size exists error, during penetrating shank of bolt, sometimes result in the bolt hole deformation on callosity excessive, there is the phenomenon destroying callosity bolt hole.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of rubber mat, can play certain interference fit when using bolt to fix, bolt hole excessive deformation will not be made again to destroy.
For achieving the above object, this utility model provides following technical scheme: a kind of rubber mat, including callosity body, callosity is the most internal is provided with bolt hole, it is characterized in that: bolt hole inwall is provided with multiple axial circular arc projection, bolt hole inwall surrounds a deformable cavity with adjacent two circular arc projection sides.
This utility model is preferred: described this body side surface of callosity is provided with some grooves for absorbing vibrations.
This utility model is preferred: the height of described circular arc projection is 0.05 ~ 0.1 with the ratio of diameter of bolt hole.
This utility model is preferred: described circular arc number of slugs is 20, and circular arc projection is along bolt hole inwall circumference uniform distribution.
Compared with prior art, the beneficial effects of the utility model are: bolt hole inwall is provided with multiple axial circular arc projection, and bolt hole inwall surrounds a deformable cavity with adjacent two circular arc projection sides, and when loading bolt, bolt will not directly contact with bolt hole.The circular arc projection being arranged on bolt hole produces interference fit with bolt, circular arc projection top is compressed, produce certain magnitude of interference, ensure that callosity can be securely fixed in frame by bolt, circular arc projection is toward the deformable cavity homogeneous deformation of its both sides simultaneously, will not destroy bolt hole because deformation is excessive.In addition, when machine produces horizontal vibrations, circular arc projection so arranges and also can preferably absorb transverse vibration.

Detailed description of the invention
Referring to figs. 1 through Fig. 3, this utility model rubber mat embodiment is described further.
A kind of rubber mat, including callosity body 1, bolt hole 2 it is provided with in callosity body 1, bolt hole 2 coordinates with installing bolt, bolt inserts callosity body interior from callosity body lower surface, bolt hole lower surface is provided with is easy to the chamfering 3 that shank of bolt penetrates, bolt head is conflicted with callosity body 1 inner wall end surface, shank of bolt stretches out callosity body 1 upper surface threadeds with frame, bolt hole inwall is provided with multiple axial circular arc projection 4, circular arc projection 4 and bolt interference fit, bolt hole 2 inwall surrounds a deformable cavity 5 together with adjacent two circular arc projection 4 sides, deformable cavity 5 opening is towards the bolt hole center of circle.When circular arc projection 4 and bolt interference fit, the top of circular arc projection 4 is compressed, circular arc projection 4, toward deformable cavity 5 homogeneous deformation of its both sides, had both been avoided that and has caused because deflection is excessive callosity bolt hole 2 to be cracked owing to rubber mat is connected loosely to it also avoid with bolt.Additionally, when machine produces horizontal vibrations, circular arc projection 4 can be deformed, and preferably absorbs transverse vibration, it is ensured that the stability of rubber mat supporting.
This body side surface of callosity is provided with some grooves 6 for absorbing vibrations.When machine produces vertical vibrations, at groove 6 less due to wall thickness, be first deformed, absorb a part vibrations, thereafter callosity body bulk deformation again, by remaining shock absorption, so arrange and can increase the deformation space of callosity, make rubber mat that rubber mat entirety will not be caused because not having deformation space to be destroyed by pressure break, reduce the fatigue strength of callosity body simultaneously, need not reduced overall when shaking less, effectively prevent callosity body aging, improve the life-span of callosity.
1.02 ~ 1.07 times of a diameter of diameter of bolt of rubber mat bolt hole 2, the bolt hole 2 of rubber mat is slightly larger than shank of bolt diameter, for circular arc projection 4 and deformable cavity 5 headspace, circular arc projection 4 protrudes the height of bolt hole and bolt hole 2 diameter ratio between 0.05 ~ 0.1.If bolt hole 2 diameter is excessive, callosity and frame can not be connected by bolt well, and when machine run produces vibrations, rubber mat can not absorb the vibrations that machine produces well, not have the effect of bradyseism, and the preferred ratio of the present embodiment is 1.05.When the height of circular arc projection 4 is the 0.05 ~ 0.1 of diameter of bolt hole, circular arc projection 4 can produce interference fit with bolt effectively, ensure that rubber mat is connected as a single entity securely by bolt with frame, the deformation that circular arc projection 4 produces can be accommodated by deformable cavity 5 and fill up deformable cavity, making not only to produce interference fit but also bolt hole 2 will be caused to be destroyed because of deflection is excessive between bolt and rubber mat, the preferred crown height of the present embodiment is 0.08 with the ratio of diameter of bolt hole.
Circular arc projection 4 quantity is 20 and along bolt hole 2 inwall circumference uniform distribution, when bolt penetrates bolt hole 2,20 circular arc projections can provide enough magnitudes of interference, circular arc projection 4, along bolt hole inwall circumference uniform distribution, makes stress and deformation the most uniform, reduces the destruction to circular arc projection 4.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
