Abstract
The utility model discloses a sample clamp which comprises a rigid fixing clamp, wherein a metal pressing block and a metal fixing plate are respectively arranged on two inner walls of a jaw of the rigid fixing clamp, a metal connecting rod is arranged on the upper surface of the jaw of the rigid fixing clamp, and the metal connecting rod penetrates through the metal fixing plate. The metal fixing plate is arranged at one end of the rigid metal clamp, the metal pressing block is arranged at the other end of the rigid metal clamp, the metal fixing plate and the metal pressing block are parallel to each other, and a deformed welding test piece is placed between the metal fixing plate and the metal pressing block, so that the welding test piece can be leveled, and the subsequent machining of the welding test piece can be facilitated.
Description
Technical Field
The utility model relates to the field of clamps, in particular to a sample clamp.
Background
The welding test piece is a test piece for verifying the performance of the weld joint. The welding test piece can generate deformation through uneven heating, the locally heated metal expands in the welding process, the expansion is restrained by surrounding cold metal, so that thermal stress is caused and plastic deformation is caused, local contraction is generated when a welding seam molten pool is cooled, the contraction is restrained by the surrounding, the contraction amount cannot offset the expansion deformation caused in the heating process, and residual deformation is left. Generally, a reversible deformation measure is adopted, but the deformation cannot be completely eliminated, and the deformation increases the difficulty of machining a test piece, so that the size precision of the test piece is reduced, and the final test result is possibly inaccurate or even fails.
An effective solution to the problems in the related art has not been proposed yet.
SUMMERY OF THE UTILITY MODEL
Aiming at the technical problems in the related art, the utility model provides a sample clamp which can reduce the problem that the deformation of a test piece influences the accuracy of a test result.
In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:
the sample clamp comprises rigid fixing pliers, wherein metal pressing blocks and metal fixing plates are respectively arranged on two inner walls of a jaw of the rigid fixing pliers, and metal connecting rods penetrate through the metal fixing plates and are arranged on the upper surfaces of the jaws of the rigid fixing pliers.
Furthermore, the metal pressing block and the metal fixing plate are arranged in parallel.
Furthermore, the metal pressing block and the metal fixing plate are both cuboid metal blocks.
Furthermore, the metal connecting rod is located at the central line of the upper end of the metal fixing plate.
Furthermore, a gap is reserved between the metal pressing block and the metal fixing plate.
The utility model has the beneficial effects that:
(1) the utility model has simple structure and low cost.
(2) The metal fixing plate is arranged at one end of the rigid metal clamp, the metal pressing block is arranged at the other end of the rigid metal clamp, the metal fixing plate and the metal pressing block are parallel to each other, and a deformed welding test piece is placed between the metal fixing plate and the metal pressing block, so that the welding test piece can be leveled, and the subsequent machining of the welding test piece can be facilitated.
(3) The metal fixing plate is connected to the rigid metal pliers through the metal connecting rod, and can be detached conveniently. And the distance between the metal fixing plate and the metal pressing block can be adjusted at any time, so that welding test pieces with different thicknesses can be leveled conveniently.
