Technical field
The utility model relates to a kind of welding tooling anchor clamps, belongs to welding technology field.
Background technology
At present, in the civil engineering equipment making of domestic nuclear power engineering building, comprise in the containment steel liner, a large amount of structural members such as steel construction, make and adopt buried arc welding method, speed of welding is fast, quality is good, but its welding operation worker will obtain the civilian nuclear safety equipment welder welding operation worker certification that State Bureau of Nuclear Safety issues in advance.Therefore, by " civilian nuclear safety equipment welder welding operation wage lattice administrative provisions (HAF603) " requirement, be the most important condition of being engaged in the civil engineering equipment making of nuclear power station by the operation item examination.
By " civilian nuclear safety equipment welder welding operation wage lattice administrative provisions (HAF603) " requirement, submerged-arc welding test piece length is generally 600mm, post welding distortion angle θ≤3 °, weld edge linearity≤3mm, the unfitness of butt joint of test specimen must not be test piece thickness greater than 10%T(T), and≤2mm, the nondestructive testing of test specimen should meet the examination requirements of civilian nuclear safety device product first-order weld.
Understand according to the applicant, because test piece length is longer, the sweating heat input is large, easily produces welding deformation, and the post welding distortion angle can't guarantee, the weld seam Non-Destructive Testing is difficult to reach the examination requirements of first-order weld, and the rate of passing the examination is lower.
The utility model content
The technical problems to be solved in the utility model is not enough for prior art, proposes a kind of nuclear power submerged-arc welding examination frock clamp.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of nuclear power submerged-arc welding examination frock clamp, comprise platform and the first backing plate of being located at the test piece below, described the first backing plate is located on the platform, described test piece comprises two block plates of docking, described two block plate joints are shaped with banjo fixing butt jointing, described platform has two row's screwed holes of fastening bolt being installed and being oppositely arranged, described the first backing plate is located at two row's screwed holes side respect to one another, described two row's screwed holes side away from each other is provided with the adjustment backing plate, described fastening bolt passes the compression test plate (panel) and screws in screwed hole, and described compression test plate (panel) is located at test piece and is adjusted on the backing plate.
Improvement of the technical scheme is: described platform is shaped with through hole, and described screwed hole is formed by the nut that is welded in the platform through hole.
Improvement of the technical scheme is: described test piece below also is provided with the second backing plate, and described the second backing plate is shaped with groove below relatively described two block plate joints.
Improvement of the technical scheme is: described the second backing plate is backing plate made of copper.
The utility model has designed nuclear power submerged-arc welding examination frock clamp, compared to existing technology, the beneficial effect that has is: 1) owing to being provided with the first backing plate at platform, platform has two row's screwed holes of fastening bolt being installed and being oppositely arranged simultaneously, be provided with the adjustment backing plate by two row's screwed holes side away from each other, test piece is located on the first backing plate, last fastening bolt passes the compression test plate (panel) and screws in screwed hole, compressing test plate (panel) is located on test piece and the adjustment backing plate, controlled the welding deformation amount of test piece, guaranteed after the banjo fixing butt jointing welding to test piece the linearity of test piece weld seam; 2) because the second backing plate is backing plate made of copper, the second backing plate is located at the test piece below simultaneously, guaranteed in the banjo fixing butt jointing welding process to test piece, can conduct the heat of welded seam area timely, controlled the welding deformation amount of test piece.
