Description
Technical field
The utility model relates to a kind of positioner.Be that two sections square tubes are the end-to-end flexible positioner of square tube welding that welds together usefulness specifically.
Background technology
At present, it all is artificial positioning mode that two sections square tubes are the end-to-end method that welds together location usefulness, promptly welds after the pipeline outside adopts manual method that two sections square tubes are fixed together again.Also can realize location, the butt joint of two sections square tubes though adopt artificial localization method, but need many people to help just can finish positioning and fixing during welding, not only can't realize one man operation, artificial many, the inefficiency that needs, and be difficult to accurate location, can not guarantee the pipeline that docks with one heart, the feasible pipeline quality that docks is relatively poor.
The utility model content
Problem to be solved in the utility model provides the flexible positioner of a kind of square tube welding.Use this square tube apparatus for welding and positioning that two sections square tubes are positioned, can not only locate accurately, guarantee that the pipeline that docks is concentric, improve the pipeline quality of butt joint, and can increase work efficiency greatly.
For addressing the above problem, the utility model is taked following technical scheme:
Characteristics of the present utility model are to contain check lock lever, this check lock lever by first～the 44 conical section be successively in the same way, moving type is formed by connecting.The outer end of first conical section is that small end is connected to cylindrical section, and this cylindrical section is a double-screw bolt, and its outer end is furnished with locking nut.There is circumferential boss promptly big end end, the outer end of the 4th conical section.There is concentric locking collar the outside of check lock lever, and the two ends of concentric locking collar offset with locking nut and circumferential boss respectively.And have four through holes on corresponding that section concentric locking collar of each awl property section, these four through holes are circumferentially uniform along concentric locking collar.In each through hole on the concentric locking collar adjusting steel ball is arranged all, the relative two sides of regulating steel ball respectively with check lock lever on corresponding conical section and the contacted inner surfaces of latch.There is screw thread the outside of concentric locking collar, is rotary with four spacing collars on it, and the inner surface of these four spacing collars and outer surface are circular and square respectively, and they are screwed in every circle groove upside of concentric locking collar respectively.On four limits of spacing collar axial groove is arranged all, be processed with pin-and-hole on the two side of axial groove accordingly, bearing pin is all arranged in every pair of pin-and-hole, all be hinged with latch on each bearing pin.Circular diameter equates and the two is and is slidingly matched in the outside diameter of first～the 4th conical section and the concentric locking collar.
First and the big end center of third hand tap shape section spherical pore is all arranged, steel ball is arranged in the spherical pore, be movable between steel ball and corresponding spherical pore and cooperate.Be fixed with connecting rod on the steel ball, connecting rod stretches out outside spherical pore.Center screw is all arranged on the small end of the second and the 4th spherical segment, on the steel ball connecting rod in the first and the 3rd spherical pore external screw thread is arranged all, this two connecting rod screws in respectively in the center screw on the second and the 4th spherical segment small end.
Wherein, first and third hand tap shape Duan Shangjun axial center hole is arranged, circumferential step is arranged at axial center hole bottom.In that section axial center hole more than the circumferential step limited block is arranged, on the limited block cylindrical and in that section axial center hole on the circumferential step external screw thread and internal thread are arranged respectively, the two spins together by this internal and external threads.Said spherical pore is opened the lower surface center at limited block, and its mouth diameters is less than the diameter of spherical pore.
Take such scheme, have the following advantages:
Since square tube of the present utility model welding with its check lock lever of flexible positioner by four conical sections be in the same way, moving type is formed by connecting.The outer end of first conical section is that small end is connected to cylindrical section, and this cylindrical section is a double-screw bolt, and its outer end is furnished with locking nut.There is concentric locking collar the outside of check lock lever, and the two ends of concentric locking collar offset with locking nut and circumferential boss respectively.The outside screw thread of concentric locking collar is rotary with four spacing collars on it, the inner surface of these four spacing collars and outer surface are circular and square respectively, and they are screwed in every circle groove upside of concentric locking collar respectively.On four limits of spacing collar axial groove is arranged all, be processed with pin-and-hole on the two side of axial groove accordingly, bearing pin is all arranged in every pair of pin-and-hole, all be hinged with latch on each bearing pin.Circular diameter equates and the two is and is slidingly matched in the outside diameter of first～the 4th conical section and the concentric locking collar.And have four through holes on corresponding that section concentric locking collar of each awl property section, these four through holes are circumferentially uniform along concentric locking collar.In each groove on the concentric locking collar adjusting steel ball is arranged all, the relative two sides of regulating steel ball respectively with check lock lever on corresponding conical section and the contacted inner surfaces of latch.Employing utilizes the adjusting steel ball of different-diameter by four adjusting rods of forming of conical section in the same way, is being realized location and fixing by weldering square tube inside.Thereby can utilize slew gear to realize the continuous revolution welding of square tube.Do not need other people to help just can finish positioning and fixing during welding, not only can realize the one man operation, need manually less, high efficiency, and the pipeline that can accurately locate, guarantee to demonstrate,prove butt joint with one heart, make the pipeline quality of butt joint improve greatly.
Again since check lock lever by four conical sections be in the same way, moving type is formed by connecting.When two sections soldered steel pipes are bend pipe or when crooked, under the effect of spherical pore and steel ball, the check lock lever of being made up of four conical sections can bending with the bending that is connect square tube, thus realized two sections by the weldering square tubes with one heart and accurate the location.
