Description

Technical Field

[0001] This utility model relates to devices in the field of ship welded joint measurement and inspection technology, and in particular to a device for measuring the weld leg size of a welded joint. Background Technology

[0002] In the assembly of ship components, many structures are arranged on curved surfaces, with natural angles between them that are not perpendicular. Currently, the measurement of weld leg dimensions for welded joints is typically done using a square and a ruler. However, in actual construction operations, the lack of constraint between the square and the ruler makes single-person operation difficult, resulting in poor stability of scale readings and significant human error, failing to meet the requirements for precise measurement and product quality inspection. Therefore, how to achieve high-precision measurement of weld leg dimensions for non-perpendicular welded joints and achieve stable scale readings has become an urgent problem to be solved. Utility Model Content

[0003] To achieve high-precision measurement of weld leg dimensions in non-perpendicular welded joints, this invention provides a welding joint weld leg dimension measuring device. This device constrains the position of the telescopic pointer on the support panel using a rotating rod, and then locks the positioning slider and fixes the position of the rotating rod using locking bolts. This allows the device to read the scale from the component being measured, solving the technical problem of inaccurate and stable measurement of weld leg dimensions in non-perpendicular welded joints using traditional methods.

[0004] The solution adopted by this utility model to solve the technical problem is:

[0005] A welding joint weld leg size measuring device includes a support panel with a semi-circular structure, the lower end of which is attached to the structural component to be measured, and a through groove on the side near the upper arc surface; a scale dial mounted on the upper arc surface of the support panel; a rotating rod, the lower end of which is mounted at the center of the support panel, the upper end of which extends outward, close to the front surface of the support panel, and swings around the center of the support panel; a telescopic pointer mounted on the upper end of the rotating rod, the tip of which points to the structural component to be measured; a positioning slider sleeved around the rotating rod and passing through the through groove of the support panel, sliding within the through groove of the support panel under the influence of the swing of the rotating rod; and a locking bolt mounted on the rear side of the positioning slider for locking the positioning slider, thereby fixing the position of the rotating rod and enabling reading the scale without the structural component to be measured.

[0006] In this embodiment, the scale dial can be replaced with the corresponding model according to the extension length of the telescopic pointer. The scale values ​​of the scale dial of each model are calculated in advance using trigonometric functions, and each angle is replaced with the corresponding linear value, which makes it easy to read the scale intuitively.

[0007] Positive effects:

[0008] This invention involves attaching a support panel to the structural component under test. A graduated dial is mounted on the upper arc surface of the support panel, and a rotating rod with a telescopic pointer is mounted at the center of the support panel. A positioning slider with a locking bolt is fitted around the rotating rod. By pre-evaluating the approximate range of the weld leg size, a suitable measuring range is determined, and a matching graduated dial is selected and mounted on the upper arc surface of the support panel. The extension length of the telescopic pointer is adjusted to align with the edge of the weld leg. The positioning slider is locked with the locking bolt, fixing the position of the rotating rod, thus allowing the scale to be read from the structural component under test. This achieves accurate and stable measurement of the weld leg size of non-perpendicular welded joints. This device is simple and convenient to operate, easy to disassemble and maintain. Measurement work can be completed independently using only this device, and it can measure the weld leg size of structural joints at various angles, effectively expanding its application range and improving construction efficiency and quality. It is suitable as a device for measuring the weld leg size of welded joints. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] As shown in the figure, a welding joint weld leg size measuring device includes:

[0015] The support panel 1 has a semi-circular structure, with its lower end face conforming to the structure to be measured, and a through groove on the side near the upper arc surface. The scale dial 2 is mounted on the upper arc surface of the support panel 1. The rotating rod 3 has its lower end mounted at the center of the support panel 1, and its upper end extends outward, close to the front surface of the support panel 1, and swings around the center of the support panel 1. The telescopic pointer 4 is mounted on the upper end of the rotating rod 3, with its tip pointing to the structure to be measured. The positioning slider 5 is sleeved around the rotating rod 3 and passes through the through groove of the support panel 1, sliding within the through groove of the support panel 1 under the influence of the swing of the rotating rod 3. The locking bolt 6 is mounted on the rear side of the positioning slider 5 to lock the positioning slider 5, thereby fixing the position of the rotating rod 3 and enabling the reading of the scale without the structure to be measured.

[0016] Specifically, the support panel 1 has a semi-circular structure design, with its lower end surface horizontal and aligned with the structure to be measured. A through groove with the same curvature as the upper arc surface is provided on the side closest to the upper arc surface. The scale dial 2 has an arc-shaped strip structure design and is bolted to the upper arc surface of the support panel 1. The lower end of the rotating rod 3 is mounted to the center of the support panel 1 via a rotating shaft, and its upper end extends outward to the outside of the scale dial 2 for reading the scale. Its rod wall is close to the front surface of the support panel 1 and swings around the center of the support panel 1. The tail end of the telescopic pointer 4 is welded... The rotating rod 3 is fixedly mounted on its upper end, with its tip pointing towards the structural component to be measured and aligned with the edge of the weld foot during measurement. The positioning slider 5 has a through hole inside and is fitted around the outer wall of the rotating rod 3. Its rear sliding part passes through the through groove of the support panel 1 and slides within the through groove of the support panel 1 under the influence of the swing of the rotating rod 3. The locking bolt 6 is assembled in the rear sliding part of the positioning slider 5 to lock the positioning slider 5, thereby fixing the position of the rotating rod 3. This allows the device to be detached from the structural component to be measured for scale reading, improving measurement stability and reducing human error during the reading process.

[0017] The scale dial 2 can be replaced with the corresponding model according to the extension length of the telescopic pointer 4. The scale values ​​of the scale dial 2 of each model are calculated in advance by trigonometric functions, and each angle is replaced with the corresponding linear value, which makes it easy to read the scale intuitively.

[0018] Specifically, the scale dial 2 can be replaced with multiple models marked with different scale values. First, the distance from the tip of the telescopic pointer 4 to the center of the support panel 1 is determined according to the extension length of the telescopic pointer 4. Then, the solder foot size values ​​corresponding to each angle when the telescopic pointer 4 extends to different lengths are calculated using trigonometric functions. Each value is marked as the scale value of the scale dial 2 of each model, thereby replacing each angle with the corresponding linear value, which makes it easy to read the scale intuitively.

[0019] Features of this utility model:

[0020] This invention involves attaching a support panel 1 to the structural component under test, mounting a graduated dial 2 on the upper arc surface of the support panel 1, and mounting a rotating rod 3 with a telescopic pointer 4 at the center of the support panel 1. A positioning slider 5 with a locking bolt 6 is fitted around the rotating rod 3. In actual use, by pre-evaluating the approximate range of the weld leg size and determining a suitable measuring range, a matching graduated dial 2 is selected and mounted on the upper arc surface of the support panel 1. The extension length of the telescopic pointer 4 is adjusted to align with the edge of the weld leg. The positioning slider 5 is then locked with the locking bolt 6 to fix the position of the rotating rod 3, allowing the dial to be read from the structural component under test. This achieves accurate and stable measurement of the weld leg size of non-perpendicular welded joints. This technical solution allows for independent operation of the measurement work, reducing human error, improving construction efficiency and quality. Furthermore, this device is simple and convenient to operate, easy to disassemble and maintain, and can measure the weld leg size of structural component welded joints at various angles, effectively expanding its applicability and reducing construction costs.
