Description

Sleeve weld auxiliary hydraulic device
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, the tapering on described swivel nut inclined-plane is consistent with the tapering of inner sleeve inwall, described inner sleeve is socketed on swivel nut inclined-plane, described inner sleeve is positioned in outer sleeve, welding inclined-plane is provided with inside the right-hand member end face of described outer sleeve, described inner sleeve right-hand member end face is provided with welding bench terrace, the middle part of described central shaft is connected with piston by bearing, 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 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 sealing ring 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.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In Fig. 1,1. swivel nut; 2. outer sleeve; 3. inner sleeve; 4. piston; 5. cylinder cap; 6. guide rod; 7. base, 8. central shaft, 9. oil filler point, 10. sealing ring, 11. cavitys, 12. bearings, 13. welding inclined-planes, 14. welding bench terraces.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See Fig. 1, a kind of sleeve weld auxiliary hydraulic device, comprises central shaft 8, the left end of central shaft 8 is threaded with swivel nut 1, and the left end of swivel nut 1 is with internal thread, and right-hand member inwall is shiny surface, and excessively coordinate with central shaft, making the right-hand member of inner sleeve and urceolus for being rigidly connected, can axiality be ensured.The right-hand member cylindrical of swivel nut 1 is provided with from left to right downward-sloping inclined-plane.The tapering on swivel nut 1 inclined-plane is consistent with the tapering of inner sleeve 3 inwall, and inner sleeve is socketed on swivel nut inclined-plane, and inner sleeve is positioned in outer sleeve, is provided with welding inclined-plane inside the right-hand member end face of outer sleeve, and inner sleeve right-hand member end face is provided with welding bench terrace; The middle part of central shaft 8 is connected with piston 4 by bearing 12, and piston 4 coordinates with cylinder cap 5; The right-hand member of central shaft 8 is provided with base 7, is connected with guide rod 6 between base 7 and cylinder cap 5; Sealing ring 10 is provided with between central shaft 8 and piston 4, the seam matched with piston 4 inner chamber is provided with on the left of cylinder cap 5, the oil filler point 9 that cylinder cap 5 is provided with is connected with the cavity 11 formed between piston 4 and sealing ring 10, and oil filler point 9 is connected with hydraulic system by pipeline.
Be provided with welding inclined-plane 13 inside outer sleeve 2 right-hand member, can firm welding be ensured.
Inner sleeve 3 left side is provided with welding bench terrace 14, can ensure firm welding.
The utility model in use, inner sleeve is enclosed within the inclined-plane of swivel nut, hydraulic oil is injected the cavity formed between piston and sealing ring 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.
