Description

A kind of novel buffer

Technical field

The present invention relates to buffer technology field, the buffer that especially a kind of damping is stable.

Background technique

Buffer is not affecting under industry equipment ride quality prerequisite, eliminating as increasing manufacturing efficiency, improving the impact of motion speed generation, vibrations, noise, guarantee safety, optimize production environment.In prior art, conventional hydraulic bjuffer, its complex structure, assembly manipulation is loaded down with trivial details, and manufacture cost is high, and its control stability is not high, does not reach desirable cushioning effect.In addition, conventional buffer uses pot type piston, in use, the oil pressure vary within wide limits at piston two ends, oil pressure poor stability, causes cushioning effect undesirable; Further, piston two ends are provided with damping spring, cause buffer internal structure complicated.

Summary of the invention

The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, provides a kind of novel buffer, and it has good buffer effect, structure is simple, easy to assembly, cost is low feature.

In order to solve the problem, the present invention adopts following scheme:

A kind of novel buffer, comprise cylinder body, be provided with piston and piston rod in cylinder body, one end of cylinder body is provided with cylinder head, and the other end installs axle sleeve and cylinder cap, and axle sleeve is equipped with sponge; Between piston and cylinder head, spring is installed, the inner of piston rod is against the end of piston, axle sleeve and cylinder cap are run through in its outer end, and to stretch out cylinder body outer and be connected with cylinder cap, one end of described piston is with the mounting groove of described spring, the end face of its other end is with oil-return groove, be communicated with by spill port between oil-return groove with mounting groove, be provided with steel ball between spill port and described mounting groove, the periphery wall of described piston is with oblique oil guide slot.

Further improvement as technique scheme:

The end of described spring is fixed in mounting groove by catch spring.

Technique effect of the present invention is:

Compact structure of the present invention, rationally, the oblique oil guide slot that outside piston side face is arranged, compare traditional helix structure or other buffer structures, its processing technology is simple, cost is low; Oblique oil guide slot ensures that the oil liquid resistance at piston two ends is gradual change type change, and oil pressure amplitude of variation is little, steady, thus ensure that the working stability that buffer is high and reliability; Only spring need be set in one end of piston in cylinder body, which simplify the internal structure of buffer.

Accompanying drawing explanation

Fig. 1 is sectional view of the present invention.

The three-dimensional structure diagram of piston in the present invention of Fig. 2 position.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.

As shown in Figure 1, the novel buffer of the present embodiment, comprise cylinder body 11, piston 9 and piston rod 19 are installed in cylinder body 11, one end of cylinder body 11 is provided with cylinder head 4, the end of cylinder head 4 is closed by hexagon socket cap head screw 1, hexagon socket cap head screw 1 is equipped with an O RunddichtringO 5, is provided with back-up ring 2 and the 2nd O RunddichtringO 3 between the outer circumferential face of cylinder head 4 and the inner peripheral surface of cylinder body 11; The other end of cylinder body 11 installs axle sleeve 13 and cylinder cap 17, dustproof gasket 16 is installed between axle sleeve 13 and cylinder cap 17, axle sleeve 13 being equipped with sponge 12, with being nested with groove 121 on sponge 12, the 3rd O RunddichtringO 14 being installed between the outer circumferential face of axle sleeve 13 and the inner peripheral surface of cylinder body 11; Be provided with spring 6 between piston 9 and cylinder head 4, axle sleeve 13 is stretched out and against the end of piston 9 in the inner of piston rod 19, is provided with jump ring 10 between the end face of inner and axle sleeve 13; Axle sleeve 13 and cylinder cap 17 are run through in the outer end of piston rod 19, and to stretch out cylinder body 11 outer and be connected with cylinder cap 20, and the end of cylinder cap 20 is provided with Capsule 21, is provided with oil sealing 15 between axle sleeve 13 and piston rod 19, is provided with and is covered with dust 18 between cylinder cap 17 and piston rod 19;

One end of piston 9 is with the mounting groove 93 of spring 6, the end of spring 6 is fixed in mounting groove 93 by catch spring 7, the end face of the other end of piston 9 is with oil-return groove 92, be communicated with by spill port 94 between oil-return groove 92 with mounting groove 93, steel ball 8 is installed between spill port 94 and mounting groove 93, the periphery wall of piston 9 is with oblique oil guide slot 91, the groove depth of oblique oil guide slot 91 diminishes from piston left end gradually to right-hand member, namely the Oil Guide gap between the outer circumferential face of piston 9 and the inner peripheral surface of cylinder body 11 is grading structure, fluid is when oblique oil guide slot 91, its oil pressure resistance increases from the left end of piston 9 gradually to right-hand member, thus realize the smooth change of oil pressure, and then improve the working stability of buffer.

As shown in Figure 1, when the present invention uses, power actuated plunger bar 19 is moved to the left, and the inner and the piston 9 of piston rod 19 offset, and promotes piston 9 and is moved to the left, spring 6 compresses, the raw extruding of fry dried food ingredients of piston 9 left end inner chamber part, due to the setting of oil guide slot 91 oblique on piston 9, now fluid enters the right-hand member of piston 9 along oblique oil guide slot 91, the oil pressure resistance of fluid increases gradually, makes the two ends oil pressure amplitude of variation of piston 9 little; The fluid part entering piston 9 right-hand member is absorbed by sponge 12, and another part enters spill port 94 along oil-return groove 92, and fluid squeezes the right-hand member of piston 9 and pushes away and extrude steel ball 8, and when pressure is larger, steel ball 8 is open, and suitably reduces right side oil pressure; When piston rod 19 moves right, the oil pocket of piston 9 left end increases, and oil pressure reduces, and the fluid of its right-hand member enters left end from spill port 94, and under the elastic force effect of spring 6, promotes piston 9 and reset.

Above illustrated embodiment is better embodiment of the present invention, only be used for conveniently the present invention being described, not any pro forma restriction is done to the present invention, have in any art and usually know the knowledgeable, if do not depart from the present invention carry in the scope of technical characteristics, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and do not depart from technical characteristics content of the present invention, all still belong in the scope of the technology of the present invention feature.
