Brief description of the drawings
Fig. 1 structural representations of the present utility model.
Embodiment
Shown in Fig. 1, it is related to a kind of new buffer for being easy to processing, including cylinder body 1, one end of the cylinder body are provided with cylinder
First 2, the other end is sequentially installed with bearing holder (housing, cover) 5 and the sheath 6 that is covered with dust, and sponge 51 is equipped with the bearing holder (housing, cover) 5；The sheath that is covered with dust
6 both sides open up fluted respectively, and oil sealing 61 is provided with the groove；The middle part of cylinder body 1 is provided with piston 3 and piston rod 4；
The inner side of cylinder head 2 is axially disposed lug boss 21, and spring installation cavity 31 is provided with the piston 3；It is arranged in cylinder body 1
The part of spring 8 be arranged on the lug boss 21, another part is arranged in the spring installation cavity 31；The piston 3
Right-hand member close to the position of piston rod 4 be provided with one through the piston 3 and by the cavity of piston 3 or so connect spill port
34, the spill port 34 is in hierarchic structure, and an oil return steel ball 33 is provided with the hierarchic structure；The piston rod 4 it is interior
End is resisted against the end of the piston 3, and its outer end is through bearing holder (housing, cover) 5 and is covered with dust and sheath 6 and stretches out that cylinder body 1 is outer to be connected with cylinder cap 7.
On the basis of above-mentioned technical proposal, in order that fluid it is more steady in oil return, can be in the spill port 34
Place is provided with oil return pad 32 with the relative position of spring 8.
On the basis of above-mentioned technical proposal, in order that cylinder cap 7 work it is relatively reliable, between cylinder cap 7 and piston rod 4
It is provided with lock-screw 71.
On the basis of above-mentioned technical proposal, in order to prevent piston rod 4 operationally passive stress and damage by pressure, can be in cylinder cap
Capsule 72 is provided with 7.
On the basis of above-mentioned technical proposal, in order to improve the sealing in buffer between all parts, the cylinder head 2
The first O-ring seal 22 is provided between cylinder body 1, it is O-shaped close to be provided with second between the bearing holder (housing, cover) 5 and the piston rod 4
Seal 41, is provided with the 3rd O-ring seal 42 between the bearing holder (housing, cover) 5 and cylinder body 1, it is described be covered with dust sheath 6 and the cylinder body 1 it
Between be provided with the 4th O-ring seal 62.
In use, external impetus driving piston rod 4 is moved to the left, the inner of piston rod 4 offsets with piston 3, promotes piston 3
It is moved to the left, spring 8 compresses, the life extruding of the fry dried food ingredients of the left end lumen portion of piston 3, and now fluid is along piston 3 and the inner chamber of cylinder body 1
The gap of body enters the right-hand member of piston 3, and the oil pressure resistance of fluid gradually increases so that the both ends oil pressure amplitude of variation of piston 3 becomes
It is small.A fluid part into the right-hand member of piston 3 is absorbed by sponge 51, and another part enters main spill port 34, and fluid is to piston 3
Right-hand member squeezes and pushes away and steel ball 33 is extruded, and when pressure is larger, steel ball 33 is open, appropriate to reduce right side oil pressure；When piston rod 4 to
When moving right, the oil pocket increase of the left end of piston 3, oil pressure reduces, and the fluid of its right-hand member enters left end from spill port 34, and in bullet
Under the elastic force effect of spring 8, piston 3 is promoted to reset.
The utility model design when, in order that buffer overall structure it is compacter, it is compact, can be on the inner side edge of cylinder head 2
It is axially arranged to have lug boss 21, spring installation cavity 31 is provided with piston 3.In this manner it is possible to directly the part of spring 8 is set
In spring installation cavity 31, another part is set on lug boss 21；Greatly reduce installing space of the spring in cylinder body 6.
When the utility model designs, traditional oil enveloping structure being arranged on bearing holder (housing, cover) is changed in the sheath two that is covered with dust
Side is symmetrically arranged with oil enveloping structure, so while original sealing effectiveness is ensured, can substantially reduce the processing of buffer
Difficulty, technique manufacturing cost is reduced, improve yield rate.
Because buffer needs emphasis point to consider the problem of gap of equipment operation is small during fabrication, therefore the external diameter of equipment will
It is strict controlled in claimed range.Buffer of the present utility model is after piston structure is changed so that and overall structure is compacter,
Run it is relatively reliable, largely meet abatement apparatus operation caused by impulsive force requirement, can effectively improve from
The service life of dynamicization equipment, effective protection equipment are not collided with operation, compared with noise caused by skinny device operation.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
