Description

Technical Field

[0001] The invention relates to the technical field of welding devices, and in particular to a welding device for assembled building steel structures. Background Art

[0002] Welding devices are equipment required to implement welding processes. When connecting beams and columns in building steel structures, positioners are needed to ensure that the actual welding angles are consistent with the design requirements so that the welded workpieces can be accurately assembled and used. By using positioners, welding operations can be more standardized. Different welding tasks only require adjusting the parameters of the angle positioner. There is no need for welders to control the angles with experience and skills, which reduces the requirements for welders' technical level and makes it easier for companies to manage and monitor welding quality.

[0003] For example, the utility model patent with announcement number CN213163826U provides a welding multi-angle adjustment positioner, in which a limit rotation mechanism is provided between the rotation positioning bar and the positioner body, which is limited at each rotation of a certain angle. The positioner can effectively increase the angle adjustment range and meet the needs of welding at various angles. However, although the positioner can adjust the angle range, it can only guarantee the angle between two planes, and cannot guarantee the spatial position between multiple planes. It also requires workers to manually control and adjust, which is troublesome to operate. Summary of the invention

[0048] In this embodiment, a first magnet 230 is fixedly provided on the lower surface of the base 200, and the first magnet 230 is used to abut against the cross bar 100.

[0050] In this embodiment, a first bearing is disposed in the base 200 , and the first bearing is connected to the first connecting shaft 310 . A second bearing is disposed in the second adjusting rod 400 , and the second bearing is connected to the second connecting shaft 330 .

[0051] Working process: First, draw auxiliary lines on the upper surface of the crossbar 100. The auxiliary lines are the boundary lines at the connection between the welding rod 110 and the crossbar 100. The auxiliary lines are parallel to the first plane, and the angle between the auxiliary lines and the second plane can be set arbitrarily. In the initial state, the first blocking plate blocks the first channel 212, the first rotary hydraulic cylinder 320 cannot rotate, the first adjustment rod 300 cannot rotate relative to the base 200, and the first adjustment rod 300 cannot be extended or retracted. The second blocking plate blocks the second channel 401, the second rotary hydraulic cylinder 410 cannot rotate, and the second adjustment rod 400 cannot rotate relative to the first adjustment rod 300.

[0052] The base 200 is placed on the upper surface of the crossbar 100 . The base 200 can be close to the auxiliary line, and the angle between the base 200 and the second plane can be any angle. The base 200 is adsorbed on the crossbar 100 by the first magnet 230 .

[0053] Then, according to the required first preset angle between the cross bar 100 and the welding rod 110, the angle between the second adjusting rod 400 and the first adjusting rod 300 is adjusted. The second limiting rod 440 is pulled so that the second limiting rod 440 moves toward the outside of the second adjusting rod 400, so that the second limiting plate no longer blocks the second channel 401, and the second oil storage chamber 420 and the third oil pipe 430 are connected. At this time, the second adjusting rod 400 can rotate relative to the first adjusting rod 300. The second adjusting rod 400 is rotated so that the second adjusting rod 400 moves in a direction away from the first adjusting rod 300, and the angle between the first adjusting rod 300 and the second adjusting rod 400 is adjusted to the first preset angle. Then, the second limiting rod 440 is released, and under the action of the second spring 442, the second limiting rod 440 is reset, thereby driving the second blocking plate to reset, and the second blocking plate blocks the second channel 401 again, and the first adjusting rod 300 and the second adjusting rod 400 no longer rotate relative to each other again.

[0054] Next, according to the second preset angle between the auxiliary line and the second plane, the angle between the first adjustment rod 300 and the base 200 is adjusted. The first limit rod 220 is pulled to move the first limit rod 220 toward the outside of the base 200, so that the first limit plate no longer blocks the first channel 212. At this time, the first oil storage chamber 210 is connected to the first oil pipe 340 and the second oil pipe 350, and the first adjustment rod 300 can rotate relative to the base 200, and the first adjustment rod 300 can be extended and retracted.

[0055] The first adjusting rod 300 is rotated until the third plane and the auxiliary line are parallel, and then the length of the first adjusting rod 300 is extended or shortened so that the third plane and the auxiliary line coincide. Then the first limiting rod 220 is released, and under the action of the first spring 222, the first limiting rod 220 is reset, thereby driving the first blocking plate to reset, and the first blocking plate blocks the first channel 212 again. At this time, the first adjusting rod 300 cannot rotate relative to the base 200, and the first adjusting rod 300 cannot be extended or retracted.

[0056] After the first preset angle and the second preset angle are adjusted, the welding rod 110 and the second adjustment rod 400 are abutted against each other, and then welding is performed. The first preset angle and the second preset angle are both any angle between 0° and 180°.

[0057] The prefabricated steel structure welding device of the present invention can arbitrarily adjust the angle between the first adjustment rod 300 and the second adjustment rod 400, and can arbitrarily adjust the angle between the first adjustment rod 300 and the base 200. First, the prefabricated steel structure welding device of the present invention can adapt to multiple angles in each angle, has stronger adaptability, reduces costs, and improves the utilization rate of equipment. Secondly, the prefabricated steel structure welding device of the present invention has more degrees of freedom and can adapt to two angles, namely the angle between the second adjustment rod 400 and the first plane, and the angle between the second adjustment rod 400 and the second plane. It can easily adapt to various different working environments and requirements, whether it is vertical or any inclined angle between the first plane of the welding rod 110 and the cross bar 100, and vertical or any inclined angle between the second plane of the welding rod 110 and the cross bar 100, it can be accurately positioned, thereby expanding its application range, having stronger versatility, and being able to adapt to different working environments and task requirements.

[0058] To place the base 200 on the cross bar 100, it is only necessary to move the base 200 close to the auxiliary line. There is no need to deliberately define the angle between the base 200 and the second plane, and there is no need to repeatedly adjust the angle between the base 200 and the second plane. It is more flexible, simple and convenient to use, allowing staff to complete tasks more conveniently. This convenience not only improves work efficiency, but also reduces the risk of errors and accidents caused by complex operations.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
