Drawings
FIG. 1 is a sectional view of the overall structure of the embodiment of the present invention;
fig. 2 is a schematic view of the installation in the embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, a wave spring damping cushion includes: first, the second nylon gasket 1, 2 of coaxial interval setting are provided with attenuator 3 and elastic element 4 between first, the second nylon gasket 1, 2. The damping force of the extension stroke of the damper 3 is larger than the damping force of the compression stroke of the damper 3. The first nylon gasket 1 and the second nylon gasket 2 are respectively fixedly connected with two ends of the damper 3, so that the elastic element 4 is clamped between the first nylon gasket 1 and the second nylon gasket 2. When the shock pad receives the exogenic action, attenuator 3 is compressed, produces axial displacement between first, the second nylon gasket 1, 2 and makes elastic element 4 atress warp. The elastic element 4 of the embodiment of the present invention is preferably a circular wave spring piece.
The damper 3 comprises a push rod 31 and a cylinder body 32, wherein the first gasket 1 is fixedly connected with the push rod 31, and the second gasket 2 is fixedly connected with the cylinder body 32. This embodiment preferably provides 4 dampers 3 between the first and second shims 1, 2. The first nylon gasket 1 is provided with 4 first connecting holes 11 which are uniformly distributed on the circumference, the tail part of the ejector rod 31 is provided with external threads, the tail part of the ejector rod 31 penetrates through the first connecting holes 11 and is respectively in threaded connection with fixing nuts on two sides of the first connecting holes 11, and two sides of the first connecting holes 11 are respectively provided with a countersunk hole for accommodating the fixing nuts, so that the first gasket 1 is fixedly connected with the ejector rod; have 4 second connecting holes 21 of circumference equipartition on the second nylon gasket 2, the counter sink that is used for holding cylinder body 32 is offered to one side that second connecting hole 21 is close to first nylon gasket 1, and the rigid coupling has dead lever 321 on the cylinder body 32, has the external screw thread on the dead lever 321, and dead lever 321 passes second connecting hole 21 and threaded connection fixation nut to make second gasket 2 and cylinder body 32 fixed connection.
The utility model discloses the same installation through-hole of size has been seted up respectively to first, second nylon gasket 1, 2 and elastic element 4's center.
As shown in fig. 2, in the present embodiment, when in use, the shock pad is sleeved on the top of the cylinder push rod 6 and located between the cylinder block 7 and the push rod head 8 through the mounting through hole at the center of the first and second nylon gaskets 1 and 2 and the elastic element 4, when the push rod 6 moves downwards under the driving of the cylinder body 7, the cylinder body 7 and the push rod head 8 can extrude the shock absorption pad arranged between the cylinder body 7 and the push rod head 8, the damper 3 is compressed, the first nylon gasket 1 and the second nylon gasket 2 move towards each other, because the damping force generated when the damper 3 is compressed is small, the movement blocking effect of the damper 3 on the first and second nylon gaskets 1 and 2 is small, axial displacement is generated between the first and second nylon gaskets 1 and 2 and the elastic element 4 is pressed, the elastic element 4 is pressed and deformed by force to absorb the vibration energy of the cylinder body 7 and the push rod head 8 so as to generate a buffering and damping effect, and therefore the impact vibration and the impact noise between the cylinder body 7 and the push rod head 8 are reduced; when push rod 6 resets upwards, the extrusion to the shock pad is removed to cylinder block 7 and putter head 8, first, second nylon gasket 1, 2 can be opened to both sides because of elastic element 4 resumes deformation, attenuator 3 also can begin to stretch under elastic element 4's effect and reset, because attenuator 3 stretches and can produce great damping force when reseing, attenuator 3 can dissipate the energy that elastic element 4 stored, thereby it is first to restrict, second nylon gasket 1, 2 is to the displacement that both sides opened, make first, second nylon gasket 1, 2 keep cliping elastic element's state.
Of course, the above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention, and all modifications made according to the spirit of the main technical solution of the present invention should be covered within the protection scope of the present invention.
