Abstract
The utility model discloses a sealed and static pressure strutting arrangement of hydro-cylinder for high-frequency vibration, including the piston rod, the piston rod middle part is equipped with the piston. The upper end of the piston is connected with a cylinder barrel; meanwhile, the lower end of the cylinder barrel is provided with a static pressure sleeve, and the outer side of the static pressure sleeve is provided with a cylinder head. In addition, a gland is sleeved at the joint of the cylinder barrel and the cylinder head. The utility model discloses a strutting arrangement has both guaranteed that fuel feeding pressure satisfies the operation requirement, also makes the clearance be unlikely to too little and flexible scratch and the wearing and tearing that lead to generate heat, and the static pressure support technique is adopted in the device to the innovation, has thoroughly solved the pneumatic cylinder that adopts the sealed direction of contact because rotational speed or vibration frequency are too high and the wearing and tearing support and guide position, and then causes the condition that the pneumatic cylinder became invalid, is of value to production, possesses the popularization nature and the practicality of preferred.
Description
Technical field
The utility model relates to the oil hydraulic cylinder technical field, concrete relates to a kind of cylinder seal and static pressure support device that is used for dither.
Background technique
The crystallizable mineral vibrator of metallurgy industry need dither (5～15Hz), to guarantee the crystallization uniform and delicate.And traditional oil hydraulic cylinder group power that has Sealing is big, and heating and wear block, can not reach effective using effect.Along with technical development,, can only be used for the production occasion of ULF or ultralow rotating speed though also there is the oil hydraulic cylinder of some no seal configurations to occur; And support and guiding heating wearing and tearing bigger; Working life is short, is unfavorable for whole production and management, also can cause extra cost allowance.
The model utility content
The purpose of the utility model is to solve the problem that exists in the existing technology, and a kind of cylinder seal and static pressure support device that is used for dither is provided.
The utility model is achieved through following technological scheme:
A kind of cylinder seal and static pressure support device that is used for dither comprises piston rod, and the piston rod middle part is provided with piston.
The piston upper end is connected with cylinder barrel; Simultaneously, the cylinder barrel lower end is provided with the static pressure cover, and the static pressure cover outside is provided with cylinder head.
In addition, the joint of cylinder barrel and cylinder head is with gland.
On the cylinder barrel symmetry be provided with left oiler and right oiler, be respectively equipped with drain tap and static pressure hydraulic fluid port between left oiler and the right oiler.
Static pressure cover bottom is provided with annular groove, is provided with dust ring in its annular groove simultaneously.
The utility model usefulness is:
The support device of the utility model had both guaranteed that charge oil pressure satisfied usage requirement; Also make the gap be unlikely to too little and heating is flexible causes scratch to pull and wear and tear; Innovation in device, adopt the static pressure support technology, thoroughly solved adopt the contact seal guiding oil hydraulic cylinder because rotating speed or vibration frequency are too high wearing and tearing support and the guiding position and then the situation that causes oil hydraulic cylinder to lose efficacy; Be of value to production, but possess preferable generalization and practicability.
Description of drawings
To combine embodiment and accompanying drawing that the utility model is done further to describe in detail below:
Fig. 1 is the integrally-built schematic representation of the utility model.
Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
A kind of cylinder seal and static pressure support device that is used for dither as shown in Figure 1 comprises piston rod 11, and piston rod 11 middle parts are provided with piston 10, and piston 10 upper ends are connected with cylinder barrel 1.
Simultaneously, cylinder barrel 1 lower end is provided with static pressure cover 6, and static pressure overlaps 6 outsides and is provided with cylinder head 5.
In addition, cylinder barrel 1 is with gland 2 with the joint of cylinder head 5.
On the cylinder barrel 1 symmetry be provided with left oiler 3 and right oiler 9, be respectively equipped with drain tap 7 and static pressure hydraulic fluid port 8 between left oiler 3 and the right oiler 9.
Static pressure overlaps 6 bottoms and is provided with annular groove, is provided with dust ring 4 in its annular groove simultaneously.
Cylinder barrel 1 inside is provided with corresponding oil transport pipeline, and left oiler 3, right oiler 9, drain tap 7 and static pressure hydraulic fluid port 8 link to each other respectively at cylinder barrel 1 inner corresponding oil transport pipeline, so that with the transmission and the drainage collection of oil.
The efficiency test of the utility model through repeatedly both guaranteed that charge oil pressure satisfied usage requirement, also made the gap be unlikely to too little and heating is flexible causes scratch to pull and wear and tear.Innovation simultaneously in device, adopt the static pressure support technology, thoroughly solved adopt the contact seal guiding hydraulic pressure because rotating speed or vibration frequency are too high wearing and tearing support and the guiding position and then the situation that causes oil hydraulic cylinder to lose efficacy.
Wherein, left oiler 3 passes in and out oily frequency with right oiler 9 through electromagnetic proportional valve control and then realizes it and produce action; The oil that drain tap 7 will leak out from the gap takes back fuel tank, and static pressure hydraulic fluid port 8 remains pressure (pressure is according to suffered load unbalance loading decision in concrete the production), acts on the piston rod 11, reaches the purpose of support and guiding.
Through the contactless support guide structure of this no Sealing of the utility model; Can effectively avoid the easy heating wear out failure that causes greatly owing to Sealing frictional force; And the heating wear problem of traditional contact-type support guide, improved oil hydraulic cylinder working life in process of production greatly.
