[0002] Temperature control between multi-layer and multi-pass welding passes is a basic way to ensure the welding quality of thick plates: the thickness range of marine steel plates is large. During the welding of thick plates, it is often necessary to perform multi-layer and multi-pass welding based on a specific form of groove. In order to ensure the welding quality, the temperature needs to be controlled between layers, and contact thermometers are generally used for measurement.

[0003] Weld appearance dimension inspection is a basic method to evaluate weld quality: in addition to meeting the basic requirements for measuring the excess height of plates of equal thickness, in order to ensure that the structural weight and cost are controllable, there are often a large number of transition welds of plates of different thicknesses in the hull, and the weld dimension inspection tooling must also meet the requirements for measuring the excess height of plates of different thicknesses.

[0004] In welding production, especially in industries with highly discrete characteristics such as shipbuilding, the workshop environment is poor and the safety risks are high. Technical and management personnel dynamically monitor the welding process and carry and use a large number of instruments, which is not only inconvenient to use, but also poses great risks to personal and equipment safety. Therefore, there is a strong demand for the functional integration of equipment and instruments. How to combine weld size measurement with welding temperature measuring elements to achieve high integration and miniaturization of measuring instruments is a technical problem that needs to be solved urgently in this field.

[0026] Embodiment 1

[0027] like Figures 1 to 3As shown, this embodiment provides a digital display weld detection ruler, including a thin plate-shaped ruler body 1, the plate surface of the ruler body 1 is attached with a plate thickness difference adapting slider 3 and a weld measuring slider 5 that can move up and down, and the weld measuring slider is arranged parallel to the front side of the plate thickness difference adapting slider;

[0028] A temperature sensor 6 is installed at the lower edge of the plate surface of the ruler body 1. The temperature sensor 6 is located at the front side of the weld measurement slider 5 to measure the temperature around the weld 22 of the two steel plates 21 when welding.

[0029] The ruler body 1 falls vertically on the surface of the steel plate, the temperature sensor 6 and the plate thickness difference adaptation slider 3 are arranged on both sides of the weld 22 and contact the two steel plates 21 respectively. By adjusting the vertical height of the plate thickness difference adaptation slider 3, the weld measurement slider 5 is made vertical to the steel plate 21 to measure the weld residual height.

[0030] Because there are many steel plates of different thicknesses in the butt joint of the hull structure, and these places are prone to quality problems due to problems such as personnel proficiency, it is necessary to focus on quality inspection from the perspective of weld appearance, etc. The plate thickness difference adaptation slider 3 is used to adapt to different plate thicknesses, especially when the thicknesses of two steel plates are different, by stretching or retracting the plate thickness difference adaptation slider 3 up and down, the ruler body 1 is ensured to be in a horizontal state, that is, the weld measurement slider 5 is in a vertical state with the steel plate 21 to measure the weld excess height.

[0031] Furthermore, the ruler body 1 includes a measuring area and a display area divided along the front-back direction, and the display area is located in front of the measuring area. The lower edge of the measuring area is higher than the lower edge of the display area. The temperature sensor 6 is fixed to the lower edge of the display area, and the plate thickness difference adaptation slider 3 and the weld measurement slider 5 are located in the measuring area.

[0032] Furthermore, the digital weld inspection ruler also includes a display screen 4, which is located in the display area of ​​the ruler body 1 and is used to display weld measurement data, including weld excess height and weld surrounding temperature. The weld excess height and weld surrounding temperature are measured simultaneously, which can be better applied to the ship hull butt joint excess height measurement scenario. In the welding of medium and thick plates, multi-layer and multi-pass welding is required, and the temperature may need to be controlled between layers, that is, the two size measurement + temperature measurement requirements are integrated into a tool.

[0033] Furthermore, the plate surface of the ruler body 1 is provided with two grooves arranged in the front-to-back direction and parallel to each other, so as to respectively accommodate the plate thickness difference adaptation slider 3 and the weld measurement slider 5. Here, the grooves are used to limit the position movement of the plate thickness difference adaptation slider 3 and the weld measurement slider 5, so that they can strictly move up and down to avoid shaking back and forth.

[0034] Furthermore, the plate thickness difference adapting slider 3 and the weld measuring slider 5 are provided with waist holes, and the adjusting knob 2 passes through the waist holes and is screwed into the plate surface of the ruler body 1, so as to achieve fixation. The adjusting knob 2 adopts a bolt-nut structure made of stainless steel material, which is located in two grooves of the ruler body 1, and its stud is fixedly connected to the ruler body, and the nut can be adjusted up and down, which plays the role of pressing the plate thickness difference adapting slider 3 and the weld measuring slider 5.

[0035] The plate thickness difference adapting slider 3 is made of stainless steel and is located in the groove of the ruler body 1. There is a waist-shaped opening in the middle, so it can move in one dimension along the groove of the ruler body 1; its relative position with the ruler body 1 is fixed by the adjusting knob 2 fixedly connected to the ruler body 1; it has the function of adapting to the measurement of the residual height of welds of plates with different thicknesses.

[0036] Similarly, the weld measuring slider 5 is also made of stainless steel and is located in the groove of the ruler body 1. It has a waist-shaped opening in the middle, so it can move in one dimension along the groove of the ruler body 1. Its relative position with the ruler body 1 is fixed by the adjusting knob 2 fixedly connected to the ruler body 1. It has the function of measuring the weld residual height. The measuring principle of the weld measuring slider 5 is similar to that of the existing electronic digital caliper, which will not be introduced in detail here.

[0037] Furthermore, the temperature sensor can move forward and backward along the lower edge of the plate surface of the ruler body 1 to adapt to welds of different sizes and different measurement conditions. More preferably, the number of the temperature sensors is more than two, and the two temperature sensors can be adjacent to ensure data credibility; or they can be spaced a certain distance apart to measure the temperature of different areas.

[0038] In summary, the utility model provides a digital display weld detection ruler, the ruler body plate surface of the digital display weld detection ruler is attached with a plate thickness difference adaptation slider and a weld measurement slider that can move up and down, and a temperature sensor is installed on the lower edge of the ruler body plate surface, and the temperature sensor is located on the front side of the weld measurement slider to measure the temperature around the weld of two steel plates when welding; the ruler body falls vertically on the surface of the steel plate, and the temperature sensor and the plate thickness difference adaptation slider are in contact with the two steel plates respectively, and by adjusting the vertical height of the plate thickness difference adaptation slider, the weld measurement slider and the steel plate are in a vertical state to measure the weld excess height. The utility model can measure the weld excess height and the temperature around the weld at the same time, so as to be better applied in the scene of measuring the weld excess height of the hull butt joint. The digital display weld detection ruler has a simple structure, is easy to maintain, is compact, and is easy to use. It also has both weld measurement and digital display functions and has a wide range of application scenarios.

Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
