Description
Technical field
The utility model relates to the driving actuator of metallurgy, mine, coal, power domain use, particularly relates to the structure of Electrohydraulic push rod.
Background technique
Electrohydraulic push rod is a kind of Novel electric liquid mechanism of mechanical-electrical-hydraulic integration, and it is based on oil hydraulic cylinder, the assembly of oil pump, motor, fuel tank, oil purifier, hydraulic control valve combination, because of its compact structure, easy to operate and be used widely.The cylinder barrel external demand welding oil storage cylinder of Electrohydraulic push rod, wall thickness because of cylinder barrel is thinner, and (working pressure is low, so the wall thickness of cylinder barrel is thin), the deformation comparison that after welding, the connecting thread place of cylinder barrel occurs is large, screwing screw thread and sealing localization part of former guide sleeve is integral type structure, the matching gap of the localization part of guide sleeve and the internal diameter of cylinder barrel is very little (because there being pressure, need sealing), as long as welding deformation amount is greater than the tolerance clearance of cooperation, screw thread will be stuck in the process screwed, once stuck, cylinder barrel will be scrapped, not only cause huge waste, and delay delivery date.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of stuck Electrohydraulic push rod of anti-screw thread easy for installation.
The purpose of this utility model is achieved in that the stuck Electrohydraulic push rod of anti-screw thread, mainly comprise the motor connected successively, coupling, oil pump, integrated package, oil cylinder, outside oil cylinder, oil storage cylinder is set, motor is arranged on outside oil storage cylinder, coupling, oil pump, integrated package is arranged in oil storage cylinder, oil cylinder mainly comprises cylinder barrel, cylinder pedestal, piston, piston rod, jaw, oil storage cylinder is stretched out in one end of cylinder barrel, and one end of oil storage cylinder is welded with cylinder barrel, cylinder pedestal is connected to cylinder barrel and is arranged on one end in oil storage cylinder, piston is arranged in cylinder barrel, one end of piston rod is connected with piston, be connected with described jaw after the other end of piston rod stretches out cylinder barrel, described cylinder barrel stretches out between one end of oil storage cylinder and piston rod and is equipped with guide sleeve, the outer end of guide sleeve arranges gland mounting groove, in gland mounting groove, gland is set, gland is threaded with cylinder barrel, welding position outside cylinder barrel and the screw position inside cylinder barrel are staggeredly arranged.
The beneficial effects of the utility model are: 1. increase, the cylinder barrel weld seam of oil cylinder and the flight pitch screwed to reduce the welding deformation of screw thread and the localization part screwed as much as possible; 2. guide sleeve adopts split type structure, guide sleeve is divided into guide sleeve and gland two parts, guide sleeve is installed required all Sealings, by in guide sleeve direct pressure cylinder barrel, then screwing gland spells tight by guide sleeve, because part gland not having Sealing and locate with cylinder barrel, screws gap between screw thread much larger than cylinder barrel welding deformation amount, so gland screws relatively lighter, screw thread stuck phenomenon can not be there is.
In order to ensure sealing effect, axle being set between described piston rod and guide sleeve and enclosing.
In order to prevent dust from entering in cylinder barrel, arrange dust ring between described piston rod and guide sleeve, dust ring is arranged on the outside of axle circle.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
