Abstract
The utility model discloses a hydraulic cylinder exhaust device, which comprises a screw plug (1) having a through hole in the middle and an exhaust bolt (2), wherein the screw plug (1) and the exhaust bolt (2) are connected and mounted on a hydraulic end cover (3) through threads; the screw plug (1) is positioned above the exhaust bolt (2) for preventing the exhaust bolt from being separated outwards; an upper end face of the screw plug (1) is embedded in the surface of the hydraulic end cover (3); a hole site (1-1) is arranged on the side edge of the screw plug (1) for riveting; a hex socket (2-1) is arranged at the upper end of the exhaust bolt (2); a conical surface (2-3) is arranged at the lower end of the exhaust bolt (2); and an exhaust groove (2-2) is arranged in the exhaust bolt. The hydraulic cylinder exhaust device is compactly structured, small in occupation, simply machined, safe in equipment work and convenient for operation.
Description
One, technical field
The utility model relates to hydraulic machinery equipment, is specifically related to Exhausted Apparatus of Hydraulic Cylinders.
Two, background technique
There is pressurized air in oil hydraulic cylinder in the cylinder when work, for avoiding vibration when working, occurring, tremble or creeping phenomenon because of the cylinder compressed air causes oil hydraulic cylinder, must the residual air in the oil hydraulic cylinder be got rid of.At present; Exhausted Apparatus of Hydraulic Cylinders structure commonly used has two kinds, is respectively integrated type outlet valve and split type outlet valve, and these two kinds of Exhausted Apparatus of Hydraulic Cylinders have simple in structure, easy to operate advantage; Its working principle is to lean on the exhaust valve head conical surface to play sealing; During exhaust, unscrew the outlet valve screw thread, air is extruded the gap between the exhaust valve head conical surface and cylinder cap and is discharged outside the cylinder in the oil hydraulic cylinder.But all there is following defective in these two kinds of Exhausted Apparatus of Hydraulic Cylinders: the one, because of to spatial requirement big so in the compact oil hydraulic cylinder of some structures outlet valve difficulty arrange; The 2nd, discharge valve apparatus obviously exposes outside oil hydraulic cylinder so very easy being damaged causes equipment failure; The 3rd, the processing of exhaust port has increased the machining difficulty.
Three, summary of the invention
The purpose of the utility model provide a kind of compact structure take up room little, processing is simple, equipment work safety, easy to operate Exhausted Apparatus of Hydraulic Cylinders.
For realizing above purpose, the plug screw and the exhaust bolt of band through hole in the middle of the utility model Exhausted Apparatus of Hydraulic Cylinders comprises, both are contained on the hydraulic pressure end cap through being threaded; Said plug screw is positioned at exhaust bolt top and is used to prevent that exhaust bolt from outwards deviating from, and the plug screw upper-end surface embeds the hydraulic pressure end cover surface, and the plug screw side also is provided with position, a hole, is used for the riveting point; Said exhaust bolt upper end is provided with interior hexagonal, the lower end is the conical surface, has air vent in the exhaust bolt.
The characteristics of above-mentioned Exhausted Apparatus of Hydraulic Cylinders: the one, replace outer-hexagonal with interior hexagonal, thereby dwindled venting gas appliance the demand on the space; The 2nd, replace the boring exhaust with the fluting exhaust, reduce the machining difficulty, it is compacter that structure seems; The 3rd, cover concrete structure at the peripheral plug screw of exhaust bolt with the band through hole; Intermediate throughholes is as the handle hole position of inner hexagon spanner; And increase position, a hole again at the plug screw side; Be used for riveting point and turn the plug screw operation, make the thread distortion from this hole through impacting the hydraulic pressure end cap when needing, prevent that stopper and screw from withdrawing from.The structure of this Exhausted Apparatus of Hydraulic Cylinders and technology are simpler than two kinds of outlet valves of the prior art; And increased firmly beforehand means; And whole device gos deep in the guide sleeve, not only is difficult for being damaged, and has increased device security; And outward appearance is also comparatively attractive in appearance, has the advantage of making simple, operation and maintenance safe ready, being beneficial to popularization.
Four, description of drawings
Accompanying drawing is the utility model Exhausted Apparatus of Hydraulic Cylinders master cross-sectional schematic.
Five, embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Shown in the accompanying drawing, the plug screw 1 and exhaust bolt 2 of band through hole in the middle of the utility model Exhausted Apparatus of Hydraulic Cylinders comprises, both are contained on the hydraulic pressure end cap 3 through being threaded; Said plug screw 1 is positioned at exhaust bolt 2 tops and is used to prevent that exhaust bolt from outwards deviating from, and plug screw 1 upper-end surface embeds the hydraulic pressure end cover surface, and side also is provided with hole position 1-1, is used for the riveting point; Said exhaust bolt 2 upper ends are that interior hexagonal 2-1, lower end are conical surface 2-3, have air vent 2-2 in the exhaust bolt.
During exhaust, the intermediate throughholes that hexagon wrench stretches into plug screw 1 is unscrewed the interior hexagonal 2-1 of exhaust bolt 2, conical surface 2-3 and hydraulic pressure end cap 3 generation gaps, and the cylinder compressed air is extruded from this gap through air vent 2-2 after the intermediate throughholes of plug screw 1 is discharged outside the cylinder; When needing fixedly plug screw 1,1-1 impacts hydraulic pressure end cap 3 thread between end cap and the plug screw is out of shape from the position, hole, prevents that stopper and screw from withdrawing from.
Claims (1)
1. Exhausted Apparatus of Hydraulic Cylinders is characterized in that: the plug screw (1) and the exhaust bolt (2) of band through hole in the middle of it comprises, and both are contained in through being threaded on the hydraulic pressure end cap (3); Said plug screw (1) is positioned at exhaust bolt (2) top and is used to prevent that exhaust bolt from outwards deviating from, and plug screw (1) upper-end surface embeds hydraulic pressure end cap (3) surface, and plug screw (1) side also is provided with position, a hole (1-1), is used for the riveting point; Said exhaust bolt (2) upper end is provided with interior hexagonal (2-1), the lower end is the conical surface (2-3), has air vent (2-2) in the exhaust bolt.
