Description
Technical field
The utility model belongs to hydraulic pressure auxiliary processing device technical field, particularly a kind of sleeve weld auxiliary hydraulic device.
Background technology
At present, when by two sleeve weld, be all generally by external force, one end of inner sleeve is clamp-oned in outer sleeve, the inwall of outer sleeve process a boss, after boss contacts with the inserting end of inner sleeve, is welding.This method of attachment is easy to cause the coaxiality deviation of inner sleeve and outer sleeve larger, the axiality of two ends respectively when assembling of inner sleeve and outer sleeve requires to be met, cause and difficulty be installed, or in Long-Time Service process junction owing to producing comparatively high pulling torque and cause fracture.
Summary of the invention
The utility model provides a kind of sleeve weld auxiliary hydraulic device that can meet axiality for solving in known technology the technical problem that exists.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of sleeve weld auxiliary hydraulic device, comprise central shaft, the left end of described central shaft is threaded with swivel nut, the left end of described swivel nut is with internal thread, right-hand member inwall is shiny surface, and excessively coordinate with central shaft, the right-hand member cylindrical of described swivel nut is provided with from left to right downward-sloping inclined-plane, and the tapering on described swivel nut inclined-plane is consistent with the tapering of inner sleeve inwall; The middle part of described central shaft is connected with piston by bearing, and the end cylindrical of described piston and inner sleeve joint is from left to right downward-sloping taper seat, and described piston coordinates with cylinder cap; The right-hand member of described central shaft is provided with base, is connected with guide rod between described base and cylinder cap; Sealing ring is provided with between described central shaft and piston, the seam matched with piston cavity is provided with on the left of described cylinder cap, the oil filler point that described cylinder cap is provided with is connected with the cavity formed between piston and sealing ring, and described oil filler point is connected with hydraulic system by pipeline.
The taper seat of described piston is connected with reinforcing ring, and the other end of described reinforcing ring is connected with the right-hand member of piston.
The advantage that the utility model has and good effect are: the utility model structure is simple, inner sleeve is enclosed within the inclined-plane of swivel nut, hydraulic oil is injected the cavity formed between piston and seal band by hydraulic system by oil filler point, promote piston to run left, piston promotes inner sleeve and also radially expands while the inclined-plane of swivel nut runs left, by outer sleeve endoporus by inner sleeve fixation, thus ensure that the axle center of inner hole of cylinder is linearly consistent with the axle center of hydraulic pressure ringfeder, then weld with outer sleeve respectively at the two ends of inner sleeve, ensure that the perpendicularity of weld bond axiality and end face, thus there is structure simple, easy to use, the axiality of inner sleeve and outer sleeve can be ensured, operating efficiency is high, extend long service life.
