Description
Technical field
The present invention relates to a kind of piston Zeng Zu mechanism, belong to Hydraulic Field.
Background technique
In the buffering of machinery; piston rod assembly often can be used to cushion; and piston rod assembly can be adjusted by the effect of fluid damping mechanism to buffering; but common damping mechanism cannot realize under different mechanical impact force; the performance of buffering is adjusted automatically and changed, easily causes the damage of machinery and piston assembly.
Summary of the invention
The object of the invention is to: a kind of piston Zeng Zu mechanism is provided, can be arranged on existing piston rod Buffer Unit, the automatic adjustment of piston compression speed can be realized.
The present invention realizes by the following method:
A kind of piston Zeng Zu mechanism, described Zeng Zu mechanism comprises shell, and described shell two ends are provided with connector of oil pipes of oil, and described enclosure is provided with cylindrical cavity;
In described cylindrical cavity, be provided with chock plug, the longitudinal direction of cylindrical cavity is provided with spacing preiection A and the spacing preiection B that internal diameter is less than chock plug diameter;
Spring bracket is provided with between cylindrical cavity end near described spacing preiection B and spacing preiection B, described spring bracket is coaxially arranged with spring A and spring B, the length of described spring A is greater than the length of spring B, and the [coefficient of of described spring A is less than the [coefficient of of spring B;
Described chock plug is fixedly connected with spring A, and described chock plug is pressed on spacing preiection A by spring A top.
As further innovation of the present invention, described spacing preiection A and spacing preiection B is provided with O-ring seal.
As further innovation of the present invention, described chock plug is provided with the penetration hole coaxial with cylindrical cavity.
As further innovation of the present invention, described chock plug is spherical.
beneficial effect
By changing the [coefficient of of two groups of springs, the automatic adjustment of the piston rod buffering rate of lathe can be made, when vibrating lower, chock plug is because can not there is start in spring A, the compression of piston rod is just realized by the damping oil hole of piston rod assembly inside self, only have when vibrating larger, chock plug just can vibrate, when making equipment run under even bearing capacity situation like this, entirety is more stable, only have when vibratory impulse is excessive, chock plug meeting Compress Spring A and spring B, close spacing preiection B, the oil circuit part of whole Zeng Zu mechanism is shut, make piston rod compression slack-off, when preventing from compressing too fast, damage is caused to machine, structure of the present invention is simple, effectively can realize the protection to equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is scheme of installation of the present invention.
Embodiment
Be described further below in conjunction with accompanying drawing
As shown in Figure 1 and 2, this product is a kind of piston Zeng Zu mechanism, main body is a columniform metal shell 1, in shell 1, turning has cylindrical cavity, two oil connections are provided with at cylindrical cavity two ends, the spring bracket of a web plate shape is had at one end end winding support of cylindrical cavity, between the other end end of spring bracket to cylindrical cavity, be provided with annular protrusion A3 and annular protrusion B2 on spring bracket, be coaxially provided with spring A5 and spring B 6, the length of spring A5 is the twice of spring B 6, [coefficient of is also the twice of spring B 6, spring A5 is connected with a spherical chock plug 4, columniform oil-through hole is processed with in chock plug 4, under state of rest, chock plug 4 is pressed on spacing preiection A3 by spring A5,
During installation, the oil connection near spacing preiection A3 is communicated with bottom the piston 8 of piston assembly, another oil connection is connected to the top of piston 8, be communicated with the head room of piston 7 and piston 8;
When equipment comparatively low speed concussion, during piston rod assembly stressed lower, chock plug 4 is pressed on spacing preiection A3 by top, damping oil circulates only by columniform oil-through hole, the equipment under running well can be made so more stable, more conveniently under equipment state of rest, workpiece can be installed simultaneously, only have when equipment is under greater impact, spring A5 is because the relation of oil pressure just can be compressed, open oil circuit, piston rod assembly is normally worked cushion, when impact force is excessive, spring A5 and spring B 6 are compressed jointly, this time, damping oil flow velocity was slack-off, piston rod assembly is compressed slack-off, prevent too fast impact from causing damage to equipment and piston rod assembly.
