[0038] The second linear slider 14 is mounted on the second linear section 121 and can slide along the length direction of the second linear section 121. The second linear slider 14 has a second zero mark that matches the second size scale 1211.

[0039] In summary, this application provides an angle-adjustable weld bead size measuring device. The main scale includes a first straight section in the shape of a strip and a first arc-shaped section in the shape of an arc. One end of the first straight section is connected to one end of the first arc-shaped section. The first straight section has a first size scale, and the first arc-shaped section has an angle scale. A first straight slider can slide on the first straight section. By aligning the first zero-position scale with the first size scale, the lower weld bead size can be accurately measured. A second arc-shaped section can slide on the first arc-shaped section of the main scale. By matching the angle zero-position scale with the angle scale, the weld joint angle can be accurately adjusted and read. A second straight slider slides on the second straight section of the angle slider. By aligning the second zero-position scale with the second size scale, the upper weld bead size can be accurately measured. The device is placed directly on the weld without cutting the weld. By adjusting the angle slider and sliding the straight slider, the weld joint angle and the upper and lower weld bead sizes can be measured simultaneously, achieving the beneficial effect of reducing the difficulty of weld measurement.

[0040] In addition, the adjustable weld bead size measuring device provided in this application embodiment can be applied to measure welds at various angles, thus improving the applicability of the device.

[0041] In one exemplary embodiment, the first arcuate portion 112 has an arcuate groove 1122 parallel to the extending direction of the first arcuate portion 112. The second arcuate portion 122 is installed in the arcuate groove 1122 and can slide within the arcuate groove 1122 along the extending direction of the first arcuate portion 112. The arcuate groove 1122 serves as a guide rail, allowing the second arcuate portion 122 of the angle slider 12 to slide smoothly and stably on the main scale 11, ensuring the accuracy and consistency of angle adjustment. The edge of the arcuate groove 1122 may also have a slope, forming a fitting engagement with the second arcuate portion 122 to prevent slippage.

[0042] Figure 6 for Figure 2 The diagram shows a partial structure of an angle-adjustable weld bead size measuring device. Figure 6 A schematic diagram of the structure of the first fastening screw is shown, combined with Figures 1-6As shown, the device also includes a first fastening screw 15, which includes a first screw rod 151 and a first screw head 152 connected to one end of the first screw rod 151. The second arcuate portion 122 has an arcuate through-hole 1221 whose extension direction is parallel to the extension direction of the second arcuate portion 122. A first screw hole 1123 is provided in the arcuate groove 1122. The first screw rod 151 of the first fastening screw 15 passes through the arcuate through-hole 1221 and is threadedly connected to the first screw hole 1123. The first screw head 152 abuts against the edge of the arcuate through-hole 1221. The first fastening screw 15 locks the angle slider at the desired angle through a threaded connection, preventing slippage during measurement. The arcuate through-hole 1221 allows the angle slider to slide freely when adjusting the angle, while the first screw hole 1123 provides a fixing point. This ensures that the position is fixed after angle measurement, avoiding measurement errors caused by accidental movement, and improving measurement reliability and ease of operation.

[0043] In one exemplary embodiment, the first screw head 152 has knurling. The knurling on the first screw head 152 increases surface roughness, providing better grip and making it easier for an operator to apply force manually when tightening or loosening the first fastening screw 15 without relying on additional tools. The knurling also disperses stress during operation, reducing wear on the first screw head 152. Simultaneously, the threaded structure of the first screw 151 mates with the threaded hole, ensuring a reliable connection.

[0044] In one exemplary embodiment, the first straight section 111 includes a first strip-shaped groove 1112, and a first linear slide 13 is mounted in the first strip-shaped groove 1112 and is capable of sliding in a direction parallel to the extending direction of the first strip-shaped groove 1112. The first strip-shaped groove 1112 serves as a linear guide, allowing the first linear slide 13 to slide along the straight direction of the main scale for measuring the lower weld toe dimension Z1. The groove edge may have a slope to form a fitting engagement with the first linear slide 13, preventing slippage. The first strip-shaped groove 1112 provides stable linear motion, ensuring the straightness and accuracy of dimensional measurements and reducing errors caused by slide wobbling. The groove structure also protects the slide from external interference, extending the service life of the device.

[0045] In one exemplary embodiment, the device further includes a second fastening screw 16, which includes a second screw rod and a second screw head connected to one end of the second screw rod. A second screw hole 1113 is provided in the first strip groove 1112, and a first strip through hole 132 parallel to the length direction of the first linear slide 13 is provided on the first linear slide 13. The second screw rod passes through the first strip through hole 132 and is threadedly connected to the second screw hole 1113. The second screw head abuts against the edge of the first strip through hole 132. The second fastening screw 16 locks the first linear slide 13 in the desired position through the threaded connection, preventing movement when measuring the lower weld toe dimension Z1. The first strip through hole 132 allows the first linear slide 13 to slide freely during dimension adjustment, while the second screw hole 1113 provides a fixing point. The second fastening screw 16 ensures the stability of the measurement of the lower weld toe dimension Z1, avoids reading errors caused by sliding, and improves measurement accuracy. The second screw head may be the same as the first screw head 152, having knurled patterns.

[0046] In one exemplary embodiment, the second straight section 121 includes a second strip-shaped groove 1212, and a second linear slide bar 14 is mounted in the second strip-shaped groove 1212 and can slide in a direction parallel to the extending direction of the second strip-shaped groove 1212. The second strip-shaped groove 1212 serves as a linear guide, allowing the second linear slide bar 14 to slide along the straight direction of the angle slide bar 12 for measuring the upper weld toe dimension Z2, providing stable linear motion and ensuring the accuracy of the upper weld toe dimension Z2 measurement. The groove edge of the second strip-shaped groove 1212 may have a slope to form a fitting fit with the second linear slide bar 14 and prevent slippage. During the measurement process, the position of the second linear slide bar 14 in the second strip-shaped groove 1212 can be adjusted independently, enabling the device to measure the upper and lower weld toes simultaneously without repeated positioning.

[0047] In one exemplary embodiment, the device further includes a third fastening screw 17, which includes a third screw rod and a third screw head connected to one end of the third screw rod. A third screw hole 1213 is provided in the second strip-shaped groove 1212, and a second strip-shaped through hole parallel to the length direction of the second linear slide 14 is provided on the second linear slide 14. The third screw rod passes through the second strip-shaped through hole and is threadedly connected to the third screw hole 1213. The third screw head abuts against the edge of the second strip-shaped through hole. The third fastening screw 17 locks the second linear slide 14 in the desired position through the threaded connection, preventing movement when measuring the upper weld toe dimension Z2. The second strip-shaped through hole allows the second linear slide 14 to slide freely during dimension adjustment, while the third screw hole 1213 provides a fixing point, ensuring the stability of the upper weld toe dimension Z2 measurement, avoiding data deviation caused by movement, and improving overall measurement reliability. The third fastening screw 17 cooperates with the second fastening screw 16 to reliably fix both linear slides. The third screw head may be the same as the first screw head 152, having knurled patterns.

[0048] In one exemplary embodiment, the first zero-point scale 131 and the second zero-point scale include a zero scale and a vernier scale. The zero scale provides a reference reading point, while the vernier scale provides a more precise subdivision reading, enabling the operator to read finer dimensions, improving the resolution and accuracy of dimensional measurements, and is suitable for welding quality inspection with high precision requirements.

[0049] In one exemplary embodiment, the ends of the first linear slide bar 13 and the second linear slide bar 14 furthest from the first arcuate portion 112 are pointed tips 133, with the angle of the pointed tips 133 being less than or equal to 30 degrees. The pointed tips 133 enable the linear slide bars to more easily contact the weld toe point, especially in narrow or hard-to-reach weld areas. When the pointed tip angle is less than or equal to 30 degrees, it ensures a close fit between the pointed tip and the weld toe point, avoiding measurement deviations caused by shape interference and improving measurement accuracy.

[0050] In summary, this application provides an angle-adjustable weld bead size measuring device. The main scale includes a first straight section in the shape of a strip and a first arc-shaped section in the shape of an arc. One end of the first straight section is connected to one end of the first arc-shaped section. The first straight section has a first size scale, and the first arc-shaped section has an angle scale. A first straight slider can slide on the first straight section. By aligning the first zero-position scale with the first size scale, the lower weld bead size can be accurately measured. A second arc-shaped section can slide on the first arc-shaped section of the main scale. By matching the angle zero-position scale with the angle scale, the weld joint angle can be accurately adjusted and read. A second straight slider slides on the second straight section of the angle slider. By aligning the second zero-position scale with the second size scale, the upper weld bead size can be accurately measured. The device is placed directly on the weld without cutting the weld. By adjusting the angle slider and sliding the straight slider, the weld joint angle and the upper and lower weld bead sizes can be measured simultaneously, achieving the beneficial effect of reducing the difficulty of weld measurement.

[0051] In addition, the adjustable weld bead size measuring device provided in this application embodiment can be applied to measure welds at various angles, thus improving the applicability of the device.

[0052] Figure 7 A flowchart illustrating a method for measuring weld leg dimensions provided in this application embodiment. This method can be used with the angle-adjustable weld leg dimension measuring device in any of the above embodiments. The specific steps of the method are as follows: Step 701: Obtain the component to be measured. The component to be measured includes a first plate, a second plate, and a weld located between the first plate and the second plate. The first plate and the second plate have an included angle greater than zero degrees.

[0053] Step 702: Place the first straight section of the main scale of the adjustable weld bead size measuring device on the first plate, and make the length direction of the first straight section parallel to the first plate, and the scale surface of the main scale perpendicular to the first plate and the second plate.

[0054] Figure 8 This is a schematic diagram illustrating a usage scenario of an angle-adjustable weld bead size measuring device provided in an embodiment of this application, combined with... Figures 1-8 As shown, the first straight section 111 of the main scale 11 is selectively connected to the first plate 31. The main scale 11 can be made of stainless steel or a magnetic material, which can be adsorbed onto the surface of carbon steel for easy measurement. The first straight section 111 has a first size scale 1111 for subsequent size reading.

[0055] Step 703: Adjust the angle slider of the adjustable weld bead size measuring device so that the length direction of the second straight section of the angle slider is parallel to the second plate and the second straight section is in contact with the second plate. Determine the included angle between the first plate and the second plate by the zero angle scale on the angle slider and the angle scale on the main scale.

[0056] The adjustment process includes selectively performing at least one of the following operations based on the initial contact state between the second straight section 121 and the second plate: Figure 9 This is a schematic diagram illustrating a usage scenario of an angle-adjustable weld bead size measuring device provided in an embodiment of this application, combined with... Figures 1 to 9 As shown, if the front end of the second straight section 121 contacts the second plate 32 and there is a gap J1 at the rear end, the angle of the angle slider 12 is increased, and / or the entire measuring device is moved away from the weld.

[0057] Figure 10 This is a schematic diagram illustrating a usage scenario of another angle-adjustable weld bead size measuring device provided in this application embodiment, combined with... Figures 1 to 10 As shown, if the rear end of the second straight section 121 contacts the second plate 32 and there is a gap J2 at the front end, the angle of the angle slider 12 is reduced, and / or the entire measuring device is moved toward the weld.

[0058] Repeat the above adjustments until the entire length of the second straight section 121 is completely aligned with the second plate 32. After the second straight section 121 is completely aligned with the second plate, operate the first fastening screw 15 to lock the relative position of the angle slide 12 and the main scale 11.

[0059] Step 704: Adjust the first linear slide installed on the main scale so that the end of the first linear slide abuts against the edge of the weld on the first plate.

[0060] After adjustment, the second screw passes through the first strip-shaped through hole 132 and is threaded into the second screw hole 1113. The second screw head abuts against the edge of the first strip-shaped through hole 132 to tighten and fix the first linear slide bar 13.

[0061] Step 705: Adjust the second linear slide installed on the angle slide so that the end of the second linear slide abuts against the edge of the weld on the second plate.

[0062] After adjustment, the third screw passes through the second through hole and is threaded into the third screw hole 1213. The head of the third screw abuts against the edge of the second through hole to tighten and fix the second linear slide bar 14.

[0063] Step 706: Determine the first weld toe size of the weld on the first plate by using the first zero mark on the first linear slide and the first size mark on the main scale, and determine the second weld toe size of the weld on the second plate by using the second zero mark on the second linear slide and the second size mark on the angle slide.

[0064] Figure 11 This is a schematic diagram illustrating a usage scenario of another angle-adjustable weld bead size measuring device provided in this application embodiment. Figure 12 for Figure 11 A schematic diagram of the three-dimensional structure. Figure 11 This diagram illustrates the structure of an adjustable weld bead size measuring device after adjustment, showing the weld bead's position. Figures 1-12 As shown, the position where the first zero mark 131 is aligned with the first size mark 1111 is read to determine the first weld toe size Z1; the position where the second zero mark is aligned with the second size mark 1211 is read to determine the second weld toe size Z2.

[0065] This yields the first weld toe dimension Z1 and the second weld toe dimension Z2 between the first and second plates, which are needed to calculate the effective thickness of the weld. The effective thickness of the weld can then be calculated.

[0066] In summary, this application provides a method for measuring weld bead size using an angle-adjustable weld bead size measuring device. The method involves acquiring the component to be measured, placing the first straight section of the main scale of the angle-adjustable weld bead size measuring device on a first plate, ensuring the length direction of the first straight section is parallel to the first plate, and the scale surface of the main scale is perpendicular to both the first and second plates. The method then adjusts the angle slider of the angle-adjustable weld bead size measuring device so that the length direction of the second straight section of the angle slider is parallel to the second plate and that the second straight section is in contact with the second plate. The method is then measured using the zero-angle scale on the angle slider and... The angle scale on the main scale determines the included angle between the first and second plates. The first linear slide on the main scale is adjusted so that its end abuts against the edge of the weld on the first plate. Similarly, the second linear slide on the angle scale is adjusted so that its end abuts against the edge of the weld on the second plate. The first weld toe dimension on the first plate is determined by the first zero-position scale on the first linear slide and the first dimension scale on the main scale. The second weld toe dimension on the second plate is determined by the second zero-position scale on the second linear slide and the second dimension scale on the angle scale. This method allows the device to be placed directly on the weld without cutting it. By adjusting the angle slide and sliding the linear slide, the weld joint angle and the dimensions of the upper and lower weld toes can be measured simultaneously, effectively reducing the difficulty of weld measurement.

[0067] In addition, the adjustable weld bead size measuring device provided in this application embodiment can be applied to measure welds at various angles, thus improving the applicability of the device.
