Abstract
The utility model discloses a kind of bulging fixture for preventing screw thread ozzle welding deformation, including screw rod (1), the screw rod (1) includes being connected and coaxial thread segment (11) and linkage section (12)；The thread segment (11) is connected with nut (2)；The external diameter of the linkage section (12) is less than thread segment (11) external diameter, and linkage section (12) end is connected with round platform (13), and round platform (13) is placed in bulging set (3) endoporus；The endoporus of the bulging set (3) includes a bellmouth, and there is screw thread bulging set (3) outer surface.The utility model fundamentally solves the problems, such as screw thread ozzle welding deformation, or even solves the problems, such as to correct the damage form of thread using screw die.The welding of stainless steel screwed tube mouth is carried out using this bulging fixture, the solder yield of screw thread ozzle is improved, ensure that the crudy of product.
Description
Technical field
The utility model belongs to manufacturing technology equipment field, particularly a kind of to prevent the swollen of screw thread ozzle welding deformation
Clamp.
Background technology
The problem of welding deformation is inevitable in stainless steel thin-walled member class product pipe joint class part welding process, it is not
Easy to control, difficulty of processing is big, and solder yield is low, dangerous.
Utility model content
The technical problems to be solved in the utility model is：A kind of bulging fixture for preventing screw thread ozzle welding deformation is provided,
Solve the problems, such as deformed threads in stainless steel thin-wall class product pipe joint class part welding process.
The technical solution of the utility model is as follows：
A kind of bulging fixture for preventing screw thread ozzle welding deformation, including screw rod, the screw rod include connected and coaxial
Thread segment and linkage section；
The thread segment is connected with nut；
The external diameter of the linkage section is less than thread segment external diameter, and linkage section end is connected with round platform, and round platform is placed in bulging set
Kong Zhong；
The endoporus of the bulging set includes a bellmouth, and there is screw thread bulging set outer surface.
One end of the thread segment first cylindrical section smooth with surface is connected, and the external diameter of the first cylindrical section is less than screw thread
Section, the first cylindrical section can be used for the guiding of nut, directly dropped when exiting thread segment prevented also from nut.
The bulging set is copper set, beneficial to radiating, is hardly damaged screw thread.
One end of the bulging set is provided with the extension for being provided with through hole, and the through-hole aperture of extension is less than nut external diameter,
And extension surface knurling, it is convenient that bulging set is threaded into ozzle.
The section outline of the extension is square or hexagon, and bulging set is threaded into connecing by convenient use spanner
In head.
Compared with existing screw thread ozzle welding manner, screw thread bulging fixture of the present utility model fundamentally solves screw thread
Ozzle welding deformation problem, or even solve the problems, such as to correct the damage form of thread using screw die.Carried out using this bulging fixture
The welding of stainless steel screwed tube mouth, the solder yield of screw thread ozzle is improved, ensure that the crudy of product.
