Description
Technical field
The utility model relates to a kind of press-loading apparatus, in particular for press-fiting the device of pipe joint and attaching nut.
Background technology
In machine-building process, there is the problem that a large amount of pipe part connects, solve problems generally adopts pipe joint to be connected with the form of attaching nut more, after pipe joint and attaching nut are first installed together by end-state position by needs, utilize external force attaching nut one end that radial deformation occurs, be fitted on pipe joint.The size of the radial load provided due to common processing mode is limited, and be difficult to provide uniform radial load, symmetry is poor, so these press-fit approach can only be used for the thinner situation of nut wall, and the precision press-fited is poor, relatively more serious to the destruction of pipe joint, the scope of application is narrow.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of device for press-fiting pipe joint and attaching nut, the relative position of pipe joint and attaching nut is fixed by arranging mandrel, cat's paw and gland are set, downward applied pressure is converted into axial force uniformly, solve exist in prior art due to strength is uneven and symmetry difference and cause to press-fit precision low, the easily technical problem of destruction pipe joint.
To achieve these goals, the technical solution used in the present invention is: for press-fiting the device of pipe joint and attaching nut, it is characterized in that: on base, be fixed with diameter by screw be less than base and the cylindrical round seat coaxial with base, base outside circle seat is provided with the spring II that bottom embeds base, the axle center of circle seat is provided with columniform mandrel, claw is had in the outer setting of mandrel, the bottom of claw is connected with circle seat with key by horizontally disposed screw I, and screw is provided with spring II; Gland is enclosed within the outside of claw, circle seat and base, and the top of internal cavity is lozenges, and bottom is taper surface, and lozenges contacts with claw lateral surface and contact surface is inclined-plane, and the upper surface of taper surface contacts with spring II, the side of taper surface and base contacts.
Base with the contact surface of gland on screw III is installed.
Described claw is six, and the outside that six claws are arranged on mandrel forms a circular platform type structure.
The beneficial effects of the utility model are: the utility model adopts said structure, the relative position of pipe joint and attaching nut is fixed by arranging mandrel, cat's paw and gland are set, downward applied pressure is converted into axial force uniformly, solve causing because strength is uneven and symmetry is poor of existing in prior art to press-fit precision low, the technical problem of easy destruction pipe joint, the utility model can exert a force uniformly to the pipe joint needing to press-fit and attaching nut, downward power is converted into axial force, ensure that symmetry and stressed even, reduce the destruction to pipe joint.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
The device for press-fiting pipe joint and attaching nut as described in Figure 1, it is characterized in that: on base 5, be fixed with diameter by screw 10 be less than base 5 and the cylindrical round seat 2 coaxial with base 5, base 5 outside circle seat 2 is provided with the spring II9 that bottom embeds base 5, the axle center of circle seat 2 is provided with columniform mandrel 4, claw 1 is had in the outer setting of mandrel 4, the bottom of claw 1 is connected with circle seat 2 with key 7 by horizontally disposed screw I3, and screw 3 is provided with spring II8; Gland 6 is enclosed within the outside of claw 1, circle seat 2 and base 5, the top of internal cavity is lozenges, and bottom is taper surface, and lozenges contacts with claw 1 lateral surface and contact surface is inclined-plane, the upper surface of taper surface contacts with spring II9, and the side of taper surface contacts with base 5.
Base 5 with the contact surface of gland 6 on screw III11 is installed.
Described claw 1 is six, and the outside that six claws 6 are arranged on mandrel 4 forms a circular platform type structure.
In use, attaching nut 13 is enclosed within positioning core axle 4, pipe joint 12 is enclosed within attaching nut 13, the endoporus of pipe joint 12 is matched with the external diameter of mandrel 4, the outer tube diameter of pipe joint 12 matches with attaching nut 13, guarantees that pipe joint 12 and attaching nut 13 rotate smooth and easy.Then install six claws 1 in outside, build gland 6, gland 6 contacts with the spring II9 of bottom, and leaves certain gap with the upper surface of base 5.Now spring II9 is in free extended configuration, ensures to keep mutually opening and smoothness of sliding between six claws.Adding man-hour, a downward active force is being applied, because have spring II9's to gland 6, so gland 6 is subjected to displacement downwards, simultaneously the inner conical surface of gland 6 coordinates with the male cone (strobilus masculinus) of cat's paw 1, applies an inside power, so just axial force is straight down converted into radial load to claw 1.After cat's paw 1 is subject to the radial load of 6 applyings, owing to there being spring I8, and the claws 1 of six composition circular platform types are inwardly subjected to displacement, and apply an inside pressure, press-fit it pipe joint 12.
As shown in Figure 2, this device adopts screw III11 to determine the relative position of gland 6 and base 5, guarantees that gland 6 axially-movable can not occur.
