Description

TECHNICAL FIELD

[0001] The utility model belongs to the welding seam fracture test equipment technical field, concretely relates to a kind of fillet weld fracture testing device. BACKGROUND

[0002] When carrying out welding operation, the welding seam is often checked to ensure the welding quality, so the welding seam needs to be fractured to check the defects of the welding seam to ensure the welding quality. Generally, the fillet weld fracture is often manually hammered to break or uses hydraulic jack to press it to break, and the hammering break not only damages the workpiece itself, but also wastes time and effort. In the process of pressing, the welding piece is easy to displace, which has great security risks. When batch fillet weld fracture is made, the efficiency is greatly affected. SUMMARY

[0003] The utility model provides a kind of fillet weld fracture testing device, for fixed fillet welding piece when carrying out fracture test, prevent its displacement, improve test security.

[0004] The fillet weld fracture testing device is characterized by comprising frame body and hydraulic jack, the frame body is composed of bottom plate, two side columns, pressing block and pressing plate, the column is symmetrically welded on the bottom plate, the distance between the two columns is greater than the diameter of the hydraulic jack, the pressing block is welded on the inner side top of column respectively, the hydraulic jack is placed on the bottom plate and located between the columns, the pressing plate is placed on the hydraulic jack, the pressing plate is composed of top plate, front and rear side plates and limiting ring, the side plate is fixed on the front and rear sides of top plate bottom surface, the limiting ring is fixed on the middle of top plate bottom surface, the outer wall of limiting ring is welded with the inner wall of front and rear side plates, the inner diameter of limiting ring matches the top surface disc of telescopic rod of hydraulic jack, the distance between front and rear side plates is less than the diameter of top surface of hydraulic jack body, when telescopic rod is retracted, side plate falls on the top surface of hydraulic jack body to form support.

[0005] Further, the handle is welded above the pressing block to lift and move the experimental device.

[0006] The utility model has the advantages that: the welding piece is placed on the pressing plate, and is lifted upward by the hydraulic jack, and the fracture test is carried out under the extrusion of the pressing block and the pressing plate. The pressing plate is provided with side plates and a limiting ring, which can form a firm fixing relationship with the hydraulic jack to prevent displacement and improve the safety of the test. In addition, only one person is needed to operate the hydraulic jack during the test, without additional personnel for hammering operation, which saves manpower and improves efficiency.
