Description

Technical Field

[0001] This application relates to the technical field of shipbuilding, and more particularly to a weld leg measuring device. Background Technology

[0002] PCTC ships have many thin plate sections, and most of the connections between sections are made by welding. The weld leg data of the welds formed by the corner welds of structures such as longitudinal skeletons and T-beams are important indicators for evaluating the amount of welding and deformation of that section.

[0003] Currently, the main method for measuring weld leg size is manual measurement using a weld leg ruler. This ruler can only measure the weld leg on one side at a time, and it's a single-point measurement, requiring two measurements to obtain data for both sides. For longer welds, measurements are typically taken at the beginning, middle, and end points of the weld, and then the average value is calculated. For fillet welds in structures like longitudinal ribs and T-beams, which are usually located on the ground, the weld leg ruler must be placed close to the ground and the measurement repeated twice. This is inconvenient and inefficient, and for longer welds, there is an inherent error in the point-by-point measurements, meaning the average value cannot accurately reflect the overall weld leg size. Therefore, the accuracy of the measurement needs improvement. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a weld leg measuring device that can solve the above-mentioned problems existing in the prior art.

[0030] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the operations (or steps) as sequential processes, many of these operations can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but it may also have additional steps not included in the figures. The process may correspond to a method, function, procedure, subroutine, subroutine, etc.

[0034] Unless otherwise stated or defined, the term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0035] For ease of description, the weld extension direction described below is the same as... Figure 1 Its left-right direction is consistent, and the up-down direction mentioned below is consistent with it. Figure 2 Its vertical direction is consistent.

[0036] like Figures 1 to 2 As shown, this embodiment provides a weld leg measuring device, including a base 10, a first depth gauge 11, a second depth gauge 12, a first elastic element 13, and a second elastic element 14.

[0037] The first depth gauge 11 is mounted on the base 10 and has a slidingly mounted first probe 111. The second depth gauge 12 is mounted on the base 10 and has a slidingly mounted second probe 121. Both the first depth gauge 11 and the second depth gauge 12 are existing measuring instruments. The first probe 111 and the second probe 121 typically refer to the depth measuring rod or depth sounding probe of the depth gauge, and are one of the key components of the depth gauge. When the first probe 111 and the second probe 121 slide, the measured value can be obtained by combining the scale readings on the first depth gauge 11 and the second depth gauge 12. The measurement results of the first depth gauge 11 and the second depth gauge 12 can be obtained manually by obtaining the scale readings on the first depth gauge 11 and the second depth gauge 12, or the first depth gauge 11 and the second depth gauge 12 can automatically obtain the measurement data and send it to the user terminal, or a combination of the above two methods can be used.

[0038] The first elastic element 13 is connected to the first probe 111 and applies a first elastic force so that the first probe 111 abuts against the weld foot of the weld 20. The first elastic element 13 causes the end of the first probe 111 to abut against the weld 20. When the weld foot measuring device moves along the extension direction of the weld 20, the end of the first probe 111 remains in contact with the weld foot on one side of the weld 20.

[0039] The second elastic element 14 is connected to the second probe 121 and applies a second elastic force so that the second probe 121 abuts against the weld foot of the weld 20. The second elastic element 14 causes the end of the second probe 121 to abut against the weld 20. When the weld foot measuring device moves along the extension direction of the weld 20, the end of the second probe 121 remains in contact with the weld foot on the other side of the weld 20.

[0040] The sliding direction of the first probe 111 and the sliding direction of the second probe 121 form a predetermined angle, so that the first probe 111 and the second probe 121 can simultaneously measure the size of both sides of the solder joint, that is, the first probe 111 and the second probe 121 simultaneously measure... Figure 2 The dimensions of D1 and D2. In the prior art, the weld leg refers to the connection between the weld 20 and the part to be welded. For example, as shown... Figure 2 As shown, the two components to be welded are a longitudinal rib 22 and a base plate 21. When the longitudinal rib 22 and the base plate 21 are perpendicular to each other, the predetermined included angle is 90 degrees. In other embodiments, the included angle between the longitudinal rib 22 and the base plate 21 can also be 120 degrees, 150 degrees, etc., in which case the predetermined included angles are 120 degrees and 150 degrees, respectively.

[0041] In use, the weld leg measuring device of this application adjusts the position of the base 10 so that the first probe 111 and the second probe 121 respectively abut against the weld legs on both sides of the weld 20. Then, the base 10 is pushed to move along the weld 20, realizing simultaneous and rapid measurement of the weld leg dimensions on both sides of the weld 20, thus improving measurement efficiency. The number of measured data can be selected according to needs, making the measurement results more accurately reflect the weld leg dimensions, providing support for subsequent weld leg control and improvement, controlling welding deformation, monitoring weld leg dimensions in thin plate segments, and having positive significance for thin plate welding process optimization and on-site process guidance.

[0042] In one embodiment, the predetermined included angle is 90 degrees, which can be used to measure the weld leg for right-angle welding of structures such as longitudinal skeletons 22 and T-beams during shipbuilding.

[0043] Optionally, the weld foot measuring device further includes a first guide wheel 15 rotatably mounted on the base 10 and / or a second guide wheel rotatably mounted on the base 10. The rotation axis of the first guide wheel 15 is parallel to the sliding direction of the first probe 111, and the rotation axis of the second guide wheel is parallel to the sliding direction of the second probe 121. The base 10 may have only the first guide wheel 15, only the second guide wheel, or both. In this embodiment, taking the base 10 with only the first guide wheel 15 as an example, the first guide wheel 15 can roll along the longitudinal rib 22, realizing the walking measurement of the weld foot measuring device, simplifying the weld foot measurement process, saving labor costs, and further improving measurement efficiency. The rotation of the first guide wheel 15 can be achieved by manually pushing the base 10 or by setting a motor to achieve automatic rotation.

[0044] Furthermore, there are multiple first guide wheels 15 and / or second guide wheels, with a first depth gauge 11 located between two of the first guide wheels 15 and / or a second depth gauge 12 located between two of the second guide wheels. The multiple first guide wheels and / or multiple second guide wheels improve the smoothness of the weld bead measuring device's movement.

[0045] In one embodiment, both the first elastic element 13 and the second elastic element 14 are columnar springs. One end of the first elastic element 13 is connected to the base 10 or the first depth gauge 11, and the other end is connected to the first probe 111. One end of the second elastic element 14 is connected to the base 10 or the second depth gauge 12, and the other end is connected to the second probe 121. In this embodiment, one end of the first elastic element 13 and one end of the second elastic element 14 are both connected to the base 10. By applying elastic force through the first elastic element 13 and the second elastic element 14, the first probe 111 and the second probe 121 respectively abut against the weld feet on both sides of the weld 20, thereby quickly measuring the weld foot dimensions D1 and D2. After the weld foot measuring device moves along the weld 20, the dimensions D1 and D2 of different measurement points of the weld foot can be obtained. Finally, by calculating the average of multiple D1 values ​​and the average of multiple D2 values, more accurate measurement data can be obtained.

[0046] Furthermore, the first probe 111 is provided with a first push plate, and there are two first elastic elements 13. The two first elastic elements 13 are arranged at intervals and both abut against the first push plate. The second probe 121 is located between the two first elastic elements 13, so that the force on the first probe 111 when it abuts against the welding foot is more stable.

[0047] Optionally, the second probe 121 is provided with a second push plate 17 and two second elastic elements 14. The two second elastic elements 14 are arranged at intervals and both abut against the second push plate 17. The second probe 121 is located between the two second elastic elements 14, so that the force on the second probe 121 when it abuts against the weld foot is more stable.

[0048] In one embodiment, the first depth gauge 11 further has a first digital display screen, and the second depth gauge 12 further has a second digital display screen. In this application, both the first depth gauge 11 and the second depth gauge 12 are digital depth gauges, which can automatically display the measured data values, reduce the labor intensity of manually reading the scale values, and improve the measurement accuracy.

[0049] Furthermore, the first depth gauge 11 also has a first communication module, and the second depth gauge 12 also has a second communication module. The first digital display screen is electrically connected to the first communication module, and the second digital display screen is electrically connected to the second communication module. The first and second communication modules can be wireless communication modules such as Bluetooth, or wired communication modules. In this embodiment, the first and second communication modules are Bluetooth, and the measured data is sent to the user terminal through the first and second communication modules. The user terminal can be the measuring personnel's mobile phone, computer, or other devices. Through the automatic continuous measurement of the first depth gauge 11 and the second depth gauge 12, more accurate measurement data can be obtained.

[0050] In one embodiment, the base 10 is provided with a handle 18 for easy gripping and pushing by the measuring personnel. Specifically, the base 10 includes a chassis 101, a frame 102 connected to the chassis 101, and a first limiting plate 103 and a second limiting plate 104 both disposed on the chassis 101. The handle 18 is connected to the frame 102. The two ends of the first elastic member 13 are respectively connected to the first limiting plate 103 and the first probe 111, and the two ends of the second elastic member 14 are respectively connected to the second limiting plate 104 and the second probe 121.

[0051] Taking the measurement of weld 20 between longitudinal rib 22 and base plate 21 as an example, the working steps of the weld leg measuring device of this application are as follows:

[0052] 1. Place the first guide wheel 15 of the welding foot measuring device against the panel of the longitudinal rib 22, and place the base 101 of the base 10 flat against the base plate 21.

[0053] 2. Adjust the first probe 111 of the first depth gauge 11 and the second probe 121 of the second depth gauge 12 so that the first probe 111 and the second probe 121 are perpendicular to the weld feet on both sides of the weld 20.

[0054] 3. Open the first depth gauge 11 and the second depth gauge 12, and use the first communication module and the second communication module to connect to the mobile phone and other user terminals.

[0055] 4. The first guide wheel 15 is driven manually or automatically to rotate, causing the weld foot measuring device to move forward along the weld seam 20, and the measurement data of the first depth gauge 11 and the second depth gauge 12 are continuously or intermittently acquired according to the measurement requirements.

[0056] 5. After measuring the weld leg of the entire weld seam 20, generate a weld leg data table on the user end and plot the weld leg change curve based on the measurement data, so that the measurement personnel can analyze the weld leg size of the entire weld seam 20 based on the data.

[0057] The technical principles of this application have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this application without inventive effort, and these embodiments will all fall within the scope of protection of this application.
