[0002] In modern industry, welding technology plays a crucial role. With the continuous development and upgrading of the manufacturing industry, the requirements for welding quality and efficiency are becoming increasingly stringent. Whether in actual welding operations or welding training, tooling and fixtures are essential to ensure the accuracy and stability of the welding process. Traditional welding methods often rely on the welder's experience and skills, making it difficult to guarantee consistent weld quality.

[0003] Fixtures and jigs can effectively hold the parts to be welded, ensuring accurate welding position and reducing welding deformation and defects. In welding competitions, reliable fixtures and jigs allow competitors to better demonstrate their technical skills and superior welding techniques. In practical training, fixtures and jigs help trainees quickly master correct welding postures and operating methods, improving welding quality. However, existing welding training fixtures have relatively simple structures, cannot simulate various welding situations, and are difficult to meet the actual needs of welding training, resulting in poor practicality.

[0045] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0046] like Figure 1As shown in the embodiment of this application, a welding training fixture is proposed, comprising: a base 11, a column assembly 12, a connecting pipe 13, a first clamping member 14, a connecting member 15, and a second clamping member 16; the column assembly 12 is vertically mounted on the base 11; the connecting pipe 13 is horizontally mounted at one end of the column assembly 12 away from the base 11, and the connecting pipe 13 is adjustablely mounted on the column assembly 12, and the connecting pipe 13 can move horizontally relative to the column assembly 12; the first clamping member 14 is adjustablely mounted on the connecting pipe 13, and the first clamping member 14 can move horizontally; the connecting member 15 is adjustablely mounted on the column assembly 12, and the connecting member 15 can move vertically along the column assembly 12; the second clamping member 16 is adjustablely mounted on the connecting member 15, and the second clamping member 16 can move vertically.

[0047] The welding training fixture provided in this embodiment includes a column assembly 12, a connecting pipe 13, a first clamping member 14, a connecting member 15, and a second clamping member 16 fixed on a base 11. The base 11 serves as the support structure of the fixture, preventing the fixture from shaking during welding and ensuring its stability, thereby improving the stability of the fixture in holding the workpiece to be welded. The column assembly 12 is set perpendicular to the base 11. The second clamping member 16 is adjustablely mounted on the column assembly 12 via the connecting member 15. By adjusting the connecting member 15, the connecting member 15 drives the second clamping member 16 to move along the column assembly 12, thereby adjusting the height of the second clamping member 16 in the vertical direction and improving the height versatility of the fixture. Adjust the position of the second clamping member 16 on the connecting member 15 to adjust the horizontal distance between the second clamping member 16 and the column assembly 12, so as to adjust the second clamping member 16 to a suitable position; the connecting pipe 13 is vertically set on the column assembly 12, and the connecting pipe 13 can move horizontally relative to the column assembly 12. The first clamping member 14 can move relative to the connecting pipe 13, thereby increasing the horizontal adjustment range of the first clamping member 14 to simulate different welding conditions and positions. It is highly practical. At the same time, the contestants can adjust the workpiece to be welded to a suitable height by adjusting the clamp according to their own welding posture and operating habits, so as to improve the welding comfort, and thus help improve the welding accuracy and welding quality.

[0048] Specifically, such as Figure 1The clamping components are used to hold the parts to be welded. The first clamping component 14 includes clamping component one 141 and clamping component two 142. Clamping component one 141 is used to fix plate-shaped workpieces so that the butt weld of the plate and tube sheet can be welded through clamping component one 141. Clamping component two 142 is used to fix small-sized tubes so that the butt weld of the small-sized tubes can be welded through clamping component two 142. The second clamping component 16 includes clamping component three 161 and clamping component four 162. Clamping component three 161 and clamping component four 162 are used to fix large-sized tubes so that the butt weld of the large-sized tubes can be welded through clamping component three 161 / clamping component four 162. During welding, the workpieces to be welded are adjusted to the required welding position and tightened by the clamps, which can realize various welding positions and welding process requirements, including flat welding position, vertical welding position, horizontal welding position, and overhead welding position.

[0049] like Figure 1 As shown, in one feasible embodiment, the first clamping member 14 is detachably connected to the connecting pipe 13; the second clamping member 16 is detachably connected to the connecting member 15.

[0050] In this technical solution, the first clamping member 14 is detachably connected to the connecting pipe 13 so as to replace the first clamping member 14 and to interchange the position of the first clamping member 14, thereby fixing different types of parts to be welded; the second clamping member 16 is detachably connected to the connecting member 15 so as to replace the second clamping member 16 and to interchange the position of the second clamping member 16, thereby fixing different types of parts to be welded.

[0051] Furthermore, the first clamping member 14 includes a first mounting post, and the second clamping member 16 includes a second mounting post. The first mounting post and the second mounting post have the same dimensions, so that the second clamping member 16 can be installed on the connector 15 and the first clamping member 14 can be installed on the connecting pipe 13. Even if the positions of the first clamping member 14 and the second clamping member 16 are interchangeable, they can be flexibly changed and combined in various ways for special welding parts, further improving the practicality of the fixture.

[0052] like Figure 1 As shown, in one feasible embodiment, the connector 15 includes: a sleeve 151, a first positioning member 152, an extension member 153, and a second positioning member 154; the sleeve 151 is fitted onto the column assembly 12, and the sleeve 151 is slidably connected to the column assembly 12; the first positioning member 152 is threadedly connected to the sleeve 151, and the first positioning member 152 is in contact with the column assembly 12 to fix the sleeve 151; the extension member 153 is disposed on the sleeve 151; the second positioning member 154 is threadedly connected to the extension member 153, and the second positioning member 154 is in contact with the second clamping member 16 to press against the second clamping member 16.

[0053] In this technical solution, the sleeve 151 is fitted onto the column assembly 12 and slidably connected to the column assembly 12. The first positioning member 152 is threadedly connected to the sleeve 151 and presses against the column assembly 12, so that the sleeve 151 is fixed to the column assembly 12 by the friction between the first positioning member 152 and the column assembly 12. The first end of the extension member 153 is disposed on the sleeve 151, and the second clamping member 16 is disposed on the second end of the extension member 153. The second positioning member 154 is threadedly connected to the extension member 153 and presses against the second clamping member 16, so that the second clamping member 16 is fixed to the extension member 153 by the friction between the second positioning member 154 and the second clamping member 16, so that the position of the second clamping member 16 after adjustment is stable and reliable.

[0054] In this technical solution, the first positioning element 152 and the second positioning element 154 are bolts, which makes the installation and disassembly of the first positioning element 152 and the second positioning element 154 simple and quick. It can be achieved simply by tightening and loosening the bolts, and can be operated with one hand. Compared with the fastening method of taking out the bolts, adjusting the angle and position, and then inserting the bolts into the corresponding holes, it is more convenient and efficient to use.

[0055] like Figure 1 As shown, in one possible embodiment, the extension 153 is arranged perpendicular to the axis of the sleeve 151.

[0056] In this technical solution, the extension member 153 extends horizontally, and the horizontal position of the second clamping member 16 is quickly adjusted by moving the second clamping member 16 on the extension member 153. The second clamping frame is used to clamp the workpiece to be welded to simulate the flat welding position.

[0057] like Figure 1 As shown, in one feasible embodiment, the extension 153 is set at an angle to the axis of the sleeve 151.

[0058] In this technical solution, the extension 153 is inclinedly disposed on the sleeve 151. The relative position between the second clamping member 16 and the column assembly 12 is quickly adjusted by moving the second clamping member 16 on the extension 153. The workpiece to be welded is clamped by the second clamping frame to simulate the angled weld position.

[0059] In one feasible implementation, the extension member 153 is cylindrical, and the angle between the axis of the extension member 153 and the axis of the sleeve 151 is 45 degrees.

[0060] In this technical solution, the extension 153 is cylindrical, and the angle between the axis of the extension 153 and the axis of the sleeve 151 is 45 degrees to simulate the 45-degree oblique welding position of the large pipe.

[0061] like Figure 1As shown, in one feasible embodiment, the column assembly 12 includes: a first column 121, a second column 122, and a first set screw 123; the first column 121 is perpendicular to the base 11 and is connected to the base 11; the second column 122 is coaxially arranged with the first column 121, the second column 122 is embedded in the first column 121, and the second column 122 is slidably connected to the first column 121; the first set screw 123 is threadedly connected to the first column 121, and the first set screw 123 is in contact with the second column 122, pressing against the second column 122; wherein, the connecting tube 13 is disposed on the second column 122.

[0062] In this technical solution, the connecting pipe 13 is set on the second column 122, the second column 122 is embedded in the first column 121 and can slide relative to the first column 121, and the second column 122 is tightened and fixed by the first set screw 123; by adjusting the position of the second column 122, the height of the connecting pipe 13 is adjusted, and then the height of the first clamping member 14 is adjusted to simulate different welding heights.

[0063] In this technical solution, the first set screw 123 is a bolt, which makes the installation and disassembly of the first set screw 123 simple and quick. It can be achieved simply by tightening or loosening the bolt, and can be operated with one hand. Compared with the fastening method of taking out the bolt, adjusting the angle and position, and then inserting the bolt into the corresponding hole, it is more convenient and efficient to use.

[0064] It should be noted that the clamp is highly versatile, as the connecting piece 15 moves up and down along the first column 121, and the second column 122 moves, driving the connecting pipe 13 up and down. This allows the clamp to meet the needs of various welding methods, including argon arc welding, CO2 gas shielded welding, and manual arc welding, reducing usage costs. It enables rapid positioning and clamping of the workpiece, reducing preparation time before welding, and is applicable to workpieces of different shapes and sizes, meeting the needs of various welding tasks in practical training. For argon arc welding, the clamp can be used to adjust the workpiece to the optimal operating height and angle, facilitating precise welding operations. For gas shielded welding, the clamp can be adjusted to the appropriate position to ensure smooth gas flow while providing good protection. For electrode welding, the clamp can be flexibly adjusted according to the electrode specifications and welding angle, and the clamping parts can firmly clamp the workpiece, effectively preventing movement and shaking during welding, thus contributing to high-quality welds.

[0065] like Figure 1As shown, in one feasible embodiment, the welding training fixture further includes: a mounting component 17 and a second set screw 18; the mounting component 17 is disposed on the second column 122, the connecting pipe 13 passes through the mounting component 17, and the connecting pipe 13 is slidably connected to the mounting component 17; the second set screw 18 is threadedly connected to the mounting component 17, and the second set screw 18 is in contact with the connecting pipe 13, pressing the connecting pipe 13 tightly.

[0066] In this technical solution, the mounting component 17 is fixed on the second column 122, and the connecting pipe 13 is connected to the second column 122 through the mounting component 17. The connecting pipe 13 can slide horizontally relative to the mounting component 17 to adjust the horizontal position of the connecting pipe 13. The second set screw 18 is threadedly connected to the mounting component 17 and tightens the connecting pipe 13 to lock the position of the connecting pipe 13 and ensure the stability of the position of the connecting pipe 13.

[0067] In this technical solution, the second set screw 18 is a bolt, which makes the installation and disassembly of the second set screw 18 simple and quick. It can be achieved simply by tightening or loosening the bolt, and can be operated with one hand. Compared with the fastening method of taking out the bolt, adjusting the angle and position, and then inserting the bolt into the corresponding hole, it is more convenient and efficient to use.

[0068] like Figure 1 As shown, in one feasible embodiment, the welding training fixture further includes: a third positioning member 19, which is threadedly connected to the connecting pipe 13, and the third positioning member 19 is in contact with the first clamping member 14, pressing against the first clamping member 14.

[0069] In this technical solution, the third positioning member 19 is threadedly connected to the connecting pipe 13 and presses against the first clamping member 14. The first clamping member 14 is fixed by the third positioning member 19 to ensure the stability of the first clamping member 14 and the workpiece to be welded on it.

[0070] In this technical solution, the third positioning component 19 is a bolt, which makes the installation and disassembly of the third positioning component 19 simple and quick. It can be achieved simply by tightening or loosening the bolt, and can be operated with one hand. Compared with the fastening method of removing the bolt, adjusting the angle and position, and then inserting the bolt into the corresponding hole, it is more convenient and efficient to use.

[0071] In one possible implementation, the length of the base 11 is greater than the length of the connecting tube 13.

[0072] In this technical solution, the length of the base 11 is greater than the length of the connecting pipe 13. The base 11 supports the entire fixture, which improves the overall load-bearing capacity of the fixture, can stably support the workpiece to be welded without deformation or damage, ensures the accuracy of welding, and has a longer service life.

[0073] Example:

[0074] All adjustments are made by bolt fixing. When adjusting the fixture or mounting the workpiece to be welded, simply tighten or loosen the bolts to adjust the position. The clamping components are detachable; simply replacing the clamping components allows for the installation of different workpieces in different positions. During the welding process, to meet the interpass temperature requirements, welding can be interspersed to achieve the required temperature for each weld. For example... Figure 1 The second clamping piece 142 can be rotated to fix the obstacle position horizontally for TIG welding of small-sized pipe fittings, and continued rotation will fix the obstacle position vertically. By changing the clamping pieces, the parts to be welded can be fixed in different positions. Placing the second clamping piece 142 on the connector 15 at the position of the fourth clamping piece 162 allows for 45-degree angled welding of small-sized pipe fittings. Placing the third clamping piece 161 on the connector 15 at the position of the fourth clamping piece 162 allows for 45-degree angled welding of large-sized pipe fittings. Rotating the first clamping piece 141 allows for horizontal and overhead welding of butt joints. All bolts on the connector 15 are adjustable in length and height. The first set screw 123 can be used to adjust the connecting pipe 13 upwards or downwards; the second set screw 18 can be used to adjust the length of the connecting pipe 13 extending to the left and right ends; and the first positioning piece 152 and the second positioning piece 154 can be used to adjust the connection to the appropriate position according to the needs of different users during welding.

[0075] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0076] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
