Embodiment 1

[0050] Comply with the above technical solutions, such as Figure 1 to Figure 6 As shown, this embodiment provides a contact type inter-plate weld reinforcement measuring device, which includes a guide sleeve 1, and a moving guide cylinder 2 that can move along the guide sleeve 1 is installed in the guide sleeve 1, and the moving guide cylinder 2 A displacement sensor 3 is fixedly installed on the top, and the end of the displacement sensor 3 is equipped with a roller 4 in contact with the workpiece 5. The roller 4 moves along the surface of the workpiece 5 under the drive of the moving guide cylinder 2, and the roller 4 touches the weld on the workpiece 5. When the seam surface is raised 6, the height of the roller 4 changes, and the reinforcement of the weld surface 6 is converted into the change of the output signal of the displacement sensor 3, and the inter-plate weld reinforcement is obtained according to the change of the output signal of the displacement sensor 3 .

Abstract

The invention provides a contact type inter-plate welding line surplus height measuring device. The device comprises a guide sleeve, wherein a movement guide cylinder which can move along the guide sleeve is arranged in the guide sleeve; a displacement sensor is fixedly arranged on the movement guide cylinder; a rolling wheel contacted with a workpiece is arranged on the end part of the displacement sensor and is driven by the movement guide cylinder to move along the surface of the workpiece. When the rolling wheel is in contact with a bump on the surface of a welding line on the workpiece, the height of the rolling wheel is changed, the surplus height of the bump on the surface of the welding line is converted into the change of an output signal of the displacement sensor, and the inter-plate welding line surplus height is obtained according to the change of the output signal of the displacement sensor; rotary movement of a driving motor is changed into the left and right movement of the displacement sensor along the welding line measuring direction, the numerical value of the welding line surplus height is converted into a certain electric signal, and welding line surplus height data is acquired by using the displacement sensor, the device has the characteristics of accurate measurement, high precision and capability of measuring welding lines with different widths and heights, and the width of the welding line can be 0.01mm.

Description

technical field [0001] The invention belongs to the field of precision measurement in industrial production, relates to the measurement of reinforcement, in particular to a contact type inter-plate weld reinforcement measurement device. Background technique [0002] With the continuous development of science and technology and the continuous improvement of industrial production levels, people's requirements for the quality of life are also getting higher and higher. High-quality welded parts occupy a high proportion in product production due to their unique advantages. However, weld reinforcement has become the main parameter and index for testing welding quality, which directly affects the subsequent process and the service life of the product. The reinforcement of the weld is the transition area between the weld and the heat-affected zone in the welded joint. It has the function of heat preservation and slow cooling for the entire weld, and plays a great role in refining t...
