Abstract
The invention discloses a bidirectional cement buffer adopting a piston type structure, wherein a piston is mounted in a sealed cylinder body fully filled with elastic cement medium; the cylinder body is a stress part; a throttling hole is formed in the piston; the piston is fixedly connected to the middle of a piston rod; and both ends of the piston rod extend out of the cylinder body. As elastic cement, which has a larger flow resistant coefficient, is taken as a damping medium to replace oil used in the prior art, the buffer can obtain larger buffering energy; and during work, the elastic size compression of the cement medium is avoided, so that the positioning accuracy is high. Moreover, due to the high oxidation resistance and the favorable sealing performance of the silica gel cement, the buffer has the characteristics of no maintenance, long service life and the like. The bidirectional cement buffer can be used for ensuring that a mobile object with large kinetic energy is stopped without impact in a target position through damping energy consumption while the stroke interval ranges from 0.2 to 1 mm. Therefore, the buffer is suitable for buffering an overweight load within a small stroke.
Description
Technical field
The present invention relates to thump, little stroke damping buffering technology, particularly relate to a kind of two-way clay buffer.
Background technique
Buffer technology all has significant application value at many industrial fields such as communications and transportation, Aero-Space, mine, metallurgy, for the protection device security, reduces and impacts, and life-saving, minimizing noise have indispensable effect.It is exactly absorption, the transfer of energy that buffer technology is searched to the bottom, and development generally has two types so far, and a kind of is the energy-storage type buffer; Elastomer like rubber, spring and other kind; This type is converted into the resiliently deformable energy with kinetic energy and stores, treat buffering course after, need energy is discharged again; This has just applied certain restoring force to load, needs the operating mode of accurate location unfavorable for some.Another kind is an energy consumption type buffer, and representative is a hydraulic bjuffer, and principle is to make it through throttle orifice through extruding hydraulic oil; Because the existence of flow resistance makes kinetic energy be converted into thermal energy consumption and falls, thereby reach the purpose of energy consumption buffering; But the hydraulic bjuffer ubiquity cushion effect that existing market is general is not enough; Cushion stroke is long, and the hydraulic oil flow resistance is lower, has action gap problems such as (project organization defectives) when beginning to move.
Summary of the invention
The present invention provides a kind of two-way clay buffer for solving the technical problem that exists in the known technology, this buffer two-way working, and the absorption energy is big, Location accuracy is high.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of two-way clay buffer; This buffer is a piston cylinder operator; Piston is installed in the cylindrical shell that is full of elastic cement medium and sealing, and said cylindrical shell is a stressed member, and said piston is provided with throttle orifice; Said piston is fixed in the middle part of piston rod, and all stretch out outside the said cylindrical shell at the two ends of said piston rod.
The outside of said cylindrical shell is the entire body screw thread.
The inside, two ends of said cylindrical shell respectively is equipped with a stuffing box gland and compresses end cap; Said stuffing box gland and the said end cap that compresses are sleeved on the said piston rod; Saidly compress the outside that end cap is arranged on said stuffing box gland, and adopt the rotary press modelling assembling with the end of said cylindrical shell.
Said piston is connected through pin with said piston rod.
Said elastic cement is the silica gel clay.
Advantage and good effect that the present invention has are: adopt elastic cement as resisting medium, abandoned traditional oil, because elastic cement has bigger flow resistance coefficient; Thereby make buffer obtain bigger buffering energy; When work, the clay medium does not have the volume elasticity compression, and Location accuracy is high.Simultaneously because the high anti-oxidation and the excellent sealing performance of silica gel clay, make buffer have characteristics such as non-maintaining and long lifetime.The present invention can will have very big kinetic energy in stroke section is 0.2-1mm moving object does not stop at the target location through the damping energy consumption with having impact.Be suitable for the superduty load, little stroke buffering is used.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1. piston 2. stuffing box glands 3. piston rods 4. compress end cap 5. cylindrical shells.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of two-way clay buffer, this buffer is a piston cylinder operator; Piston 1 is installed in the cylindrical shell 5 that is full of elastic cement medium and sealing, and cylindrical shell 5 is a stressed member, and piston 1 is provided with throttle orifice; Piston is fixed in the middle part of piston rod 3, and all stretch out outside the cylindrical shell 5 at the two ends of piston rod 3.
The outside of cylindrical shell 5 is the entire body screw thread, is convenient to install locking.Above-mentioned piston 1 is connected by the hard pin with piston rod 3; And be with cylindrical shell 5 inwalls and be slidingly matched; Cylindrical shell 5 two ends mounted inside have stuffing box gland 2 and compress end cap 4; Stuffing box gland 2 with compress end cap 4 and be sleeved on the piston rod 3, compress end cap 4 and be arranged on stuffing box gland 2 outsides, adopt the rotary press modelling assembling with the end of cylindrical shell 5.Through adopting the mode of above-mentioned rotary press modelling fitting tight, when guaranteeing sealability and intensity, reduced the axial dimension of buffer, dwindled the volume of buffer.Closed chamber in the cylindrical shell 5 is divided into two branch chambeies by piston, and the branch chamber of piston both sides can be communicated with through the throttle orifice on the piston, is full of the clay medium in the cavity; When the stressed motion of cylindrical shell; Medium will be from the branch chamber of piston one side flows to the branch chamber of piston opposite side through throttle orifice, because the clay medium has high flow resistance, it can produce certain resistance during through throttle orifice; This resistance is passed to load through cylindrical shell, reaches the buffering purpose.When work, the variable quantity of piston two side-cavity volumes is identical, and the clay medium does not have the volume elasticity compression.The size that can regulate cushion effect through the size that changes throttle orifice.
Elastic cement preferably adopts the silica gel clay with high anti-oxidation and excellent sealing property.
The present invention is improved a kind of fluid buffer in addition on the principle of hydraulic bjuffer, adopts the elastic cement medium, increases cushion effect, reduces stroke, increases rigidity.Characteristics of the present invention are two-way functions, and cushion effect is big, and cushion stroke is little, do not have the gap during startup, are particularly useful for heavy load sharp work operating mode.
Although combine accompanying drawing that the preferred embodiments of the present invention are described above; But the present invention is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
