Embodiment Construction
[0023] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] figure 1 It is a structural schematic diagram of a welding toe shape measuring device according to a preferred embodiment of the present application; figure 2 for this application figure 1 top view. Please also see figure 1 and figure 2 , the welding toe profile measurement device 100 provided in the present application includes a probe 1 , a controller 2 and a display.
[0025] The probe 1 is provided with a measuring sensor and a positioning sensor, and the end of one end of the probe 1 is needle-shaped, so as to prevent the measuring needle from being close to the base material, causing its deformation and bending due to the uneven surface of the base material, and measuring the position Will deviate from the weld toe. The measu...

The measuring device comprises a probe, a controller and a display, and is characterized in that the probe is provided with a measuring sensor and a positioning sensor, the end part of one end of the probe is needle-shaped, the measuring sensor and the positioning sensor are used for respectively sending displacement signals of the vertical direction and displacement signals of the horizontal direction; the controller is connected with the probe and used for receiving the displacement signals of the vertical direction and the displacement signals of the horizontal direction which are respectively sent by the measuring sensor and the positioning sensor; and the display is connected with the controller and displays a weld toe shape curve according to the displacement signals which are sent by the measuring sensor and the positioning sensor and received by the controller in real time.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a measuring device for welding toe appearance. Background technique [0002] The weld toe is the interface between the weld surface and the base metal. The welding seam inspection ruler can meet the requirements when measuring relatively large welds. It only needs to measure the approximate size, because the ruler end is a plane, but the factor that the welding toe is not smooth is ignored. The application in engineering generally does not consider the roughness of the weld toe, but in some research fields, such as the fatigue behavior of welded joints, the geometry of the weld toe is a factor that cannot be ignored. For example, the details of the fish scale welding toe in the weld are complicated, and the traditional weld inspection ruler cannot meet the high precision requirements. The existing measurement of the weld leg size mainly relies on the weld inspection ruler. Th...
