Abstract

The invention discloses a weld joint tensile force testing machine which comprises a base, a stationary fixing end, a movable fixing end, a pressure sensor, a hydraulic oil cylinder and a manual oil pump. The stationary fixing end is fixed to one end of the base, the movable fixing end is movably arranged at the other end of the base, mounting blocks are respectively arranged on the stationary fixing end and the movable fixing end, the hydraulic oil cylinder is fixed onto the base, a piston rod of the hydraulic oil cylinder is connected with the movable fixing end, the pressure sensor is arranged between the movable fixing end and the piston rod of the hydraulic oil cylinder, and the manual oil pump is connected with the hydraulic oil cylinder. The weld joint tensile force testing machine has the advantages that the weld joint tensile force testing machine is simple in structure, convenient to use, safe and reliable in operation and low in investment and manufacturing cost and is small, and tensile force can be accurately displayed; the weld joint tensile force testing machine is safe, accurate, light and convenient and is easy to use and operate; the weld joint tensile force testing machine is suitable for frame manufacturing units; verification of the welding quality of frames can be effectively guaranteed; the manufacturing quality of special equipment can be guaranteed, and the like.

Description

technical field [0001] The invention relates to special test equipment for frame corner fittings and column welds, in particular to a weld tensile testing machine. Background technique [0002] The frame of the long-tube trailer for transporting compressed natural gas is welded. Due to the long-distance transportation, the welding quality must be ensured. In the production process, in order to verify the reliability of the welding quality, a tensile test must be carried out on the corner fittings and column welds. Currently there is no special equipment to detect the pulling force. Tensile testing machines from other industries are generally used, but due to their bulky size, they are not easy to use. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a weld seam tensile testing machine, which can effectively detect the weld seam quality. [0004] The present invention is achieved through t...
