Description

Technical Field

[0001] This invention relates to the field of automatic welding technology, and in particular to a welding device for welded seams of bent and twisted box bodies. Background Technology

[0002] In steel structure fabrication, the main weld cover of the straight box girder is generally welded using an automated welding machine. The automated machine moves on guide rails to perform the welding (see...). Figure 1 Automatic welding, compared to manual welding, allows for continuous welding, reduces the number of weld joints, and produces aesthetically pleasing welds.

[0003] However, when the box body is in an arc-shaped, twisted form ( Figure 2 If the main weld seam of the box body is not a straight line and is not parallel to the ground plane, the automatic welding cart cannot travel in a straight line during welding and must travel in an arc-shaped and twisting manner. In this case, on the one hand, the automatic welding cart is prone to falling off the box body; on the other hand, during welding, because some areas of the box body are not parallel to the ground plane, the molten metal generated by the welding wire is prone to flowing out of the weld seam, thus affecting the overall welding effect. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a welding device for the weld seam of a bent box, which on the one hand prevents the molten metal generated by the welding wire from flowing out of the weld seam, thereby improving the overall welding quality and aesthetics, and on the other hand prevents the welding carriage from falling off the component to be welded.

[0005] This invention provides a welding device for a bent and twisted box body, including an adjusting jig and a welding carriage. The adjusting jig is used to support the component to be welded and to level the section of the component to be welded where the welding carriage is located based on feedback from the welding carriage. The welding carriage can move along the weld seam of the component to be welded, and welds the weld seam of the component during the movement, and feeds back the horizontal status of the component to the adjusting jig.

[0006] In one embodiment, the welding carriage includes a welding carriage body and an inductive switch assembly. The welding carriage body can move along the weld seam of the welding component and welds the weld seam of the component to be welded during the movement. The inductive switch assembly is mounted on the welding carriage body and is used to feed back the horizontal status of the component to be welded to the adjusting frame.

[0007] In one embodiment, the welding vehicle body includes a trolley body, a welding component, and side wheels. The trolley body is movably disposed on the component to be welded. The welding component and side wheels are assembled on the trolley body, and the side wheels slide against the contact side of the component to be welded, so that the trolley body can move along the weld seam of the component to be welded.

[0008] In one embodiment, the inductive switch assembly includes a first mercury switch and a second mercury switch mounted on the welding vehicle body. The first mercury switch is used to feed back tilt information to the adjustment frame when the welding vehicle body tilts in a first direction. The second mercury switch is used to feed back tilt information to the adjustment frame when the welding vehicle body tilts in a second direction. The first direction and the second direction are opposite.

[0009] In one embodiment, the adjusting frame includes a first support and a second support for supporting the component to be welded, wherein the first support adjusts the angle of the segment of the component to be welded where the welding carriage is located until it is horizontal according to the feedback of the welding carriage, and the second support rotates with the component to be welded.

[0010] In one embodiment, the first support base includes a first support frame, a first support seat, a telescopic rod support, and a telescopic rod. The first support frame is rotatably mounted on the first support seat to support the component to be welded. The telescopic rod is mounted on the first support seat through the telescopic rod support, and the telescopic end of the telescopic rod is connected to the first support frame to adjust the angle of the segment of the component to be welded where the welding trolley is located until it is horizontal, based on the feedback from the welding trolley.

[0011] In one embodiment, the second support base includes a second bracket and a second support base. The second bracket is rotatably mounted on the second support base to support the component to be welded and rotates with the component to be welded.

[0012] In one embodiment, the first support frame includes two limiting plates, a support plate, and a connecting plate. The two limiting plates are assembled on the same side of the support plate to form a supporting space for supporting the component to be welded. The support plate is rotatably connected to the first support seat, and the connecting plate is connected to the support plate for connecting to the telescopic end of the telescopic rod.

[0013] In one embodiment, the first support base includes a rotating plate, a horizontal plate, and a support leg. The rotating plate is connected to the horizontal plate, and the support plate is rotatably connected to the rotating plate. The support leg is connected to the horizontal plate.

[0014] In one embodiment, the welding device for the weld seam of the bending and twisting box further includes a base plate, and the adjusting jig is mounted on the base plate.

[0015] The welding device for the bending and twisting box body provided by the present invention has an adjusting frame that can adjust the section of the component to be welded, where the welding carriage is located, to be horizontal, that is, parallel to the ground plane. On the one hand, it avoids the molten metal generated by the welding wire from flowing out of the weld, thus improving the overall welding quality and aesthetics. On the other hand, it can also prevent the welding carriage from falling off the component to be welded. Attached Figure Description

Based on the description of the present invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

They are only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0023] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0024] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0025] Please refer to Figure 3 The welding device for the bending and twisting box body provided by the present invention includes an adjusting frame 1 and a welding carriage 2. The adjusting frame 1 is used to support the component 4 to be welded, and adjusts the section of the component 4 to be welded where the welding carriage 2 is located according to the feedback of the welding carriage 2. The welding carriage 2 can move along the weld seam of the component 4 to be welded, and welds the weld seam of the component 4 during the movement, and feeds back the horizontal status of the component 4 to the adjusting frame.

[0026] It can be seen that the welding device in this embodiment is designed for bent or twisted box bodies (see...). Figure 2 In this case, the component to be welded 4 is a bent box. During the welding operation, the welding carriage 2 moves along the weld seam on the component to be welded 4 and welds the weld seam while moving. When it enters the inclined section, which can be understood as the section where the component to be welded 4 is not parallel to the horizontal plane, the welding carriage 2 will move along the inclined direction and may fall off the component to be welded 4. Therefore, the welding carriage 2 itself can detect the inclination direction of the section of the component to be welded 4 where the welding carriage 2 is located. After detection, it is fed back to the adjusting frame 1. The adjusting frame 1 adjusts the section of the component to be welded 4 where the welding carriage 2 is located to be horizontal, which is the so-called leveling. In this case, the falling of the welding carriage 2 is well avoided, so as not to affect the automatic welding of the weld seam.

[0027] Please see Figure 3In some embodiments, the welding carriage 2 includes a welding carriage body and an inductive switch assembly. The welding carriage body can move along the weld seam of the welding component and welds the weld seam of the component 4 to be welded during the movement. The inductive switch assembly is mounted on the welding carriage body and is used to feed back the horizontal status of the component 4 to be welded to the adjusting frame 2. The welding carriage body includes a carriage body 205, a welding component 201 and a side wheel 202. The carriage body 205 is movably disposed on the component 4 to be welded. The welding component 201 and the side wheel 202 are mounted on the carriage body 205, and the side wheel 202 slides against the contact side of the component 4 to be welded, so that the carriage body 205 can move along the weld seam of the component 4 to be welded.

[0028] It can be understood that in this embodiment, the trolley body 205 moves on the moving side of the component 4 to be welded. The contact side is the side connected to the moving side, and the height of the moving side is higher than the side opposite to it. Of course, there can be two side wheels 202, which are respectively attached to two opposite contact sides. Both contact sides are connected to the moving side. When the trolley body 205 moves, the side wheels 202 are attached to the moving side to limit the movement trajectory of the trolley body 205 so that it moves along the weld seam. While moving, the welding work is carried out by the welding component 202. The welding component 202 can be a welding gun. The inductive switch assembly senses the tilt direction of the trolley body 205 and feeds it back to the adjustment frame 2. The adjustment frame 2 levels the section of the component 4 to be welded where the trolley body 205 is located. The section of the component 4 to be welded where the welding trolley body is located can be understood as the area to be welded. The welding trolley body structure of this structure is simple and can make the welding trolley body move along the weld seam of the component 4 to be welded.

[0029] Please see Figure 3 In some embodiments, the inductive switch assembly includes a first mercury switch 203 and a second mercury switch 204 mounted on the welding vehicle body. The first mercury switch 203 is used to feed back tilt information to the adjustment frame 2 when the welding vehicle body tilts in a first direction. The second mercury switch 204 is used to feed back tilt information to the adjustment frame 2 when the welding vehicle body tilts in a second direction. The first direction and the second direction are opposite.

[0030] It is understood that when the welding vehicle body tilts in the first direction, the first mercury switch 203 is activated. After the first mercury switch 203 is activated, the first adjustment circuit of the adjustment frame 2 and the adjustment frame 2 form a closed first control circuit, that is, the feedback to the adjustment frame 2 in this embodiment. In this case, the first control circuit controls the adjustment frame 2 to adjust the component 4 to be welded to rotate in the second direction opposite to the first direction until the component 4 to be welded reaches a horizontal state. After the component 4 to be welded reaches a horizontal state, the first mercury switch 203 is disconnected. When the welding vehicle body tilts in the second direction, the second mercury switch 204 is activated. The second mercury switch 204 connects the second adjustment circuit and the adjustment frame 2 to form a second control circuit. The second control circuit controls the adjustment of the component 4 to be welded to rotate in the first direction until the component 4 to be welded reaches a horizontal state. After the component 4 to be welded reaches a horizontal state, the second mercury switch 204 is disconnected. This structure is simple and effective, without the need for complex sensors and judgment logic for control, thus reducing costs.

[0031] Please see Figure 3 In some embodiments, the adjusting frame 2 includes a first support and a second support for supporting the component to be welded, wherein the first support adjusts the angle of the section of the component 4 to be welded where the welding carriage is located until it is horizontal according to the feedback of the welding carriage, and the second support rotates with the component 4 to be welded.

[0032] It is known that the first support and the second support can be located at the two ends of the component 4 to be welded, respectively. The second support rotates with the component 4 to be welded. It can be understood that the first support drives one end of the component 4 to be welded to rotate, and the component 4 to be welded drives the second support to rotate. In this embodiment, the angle of the section of the component 4 to be welded where the welding carriage is located is adjusted only by the first support, which can save costs to a certain extent.

[0033] Please see Figure 3 In some embodiments, the first support base includes a first support frame 105, a first support base 102, a telescopic rod support 101, and a telescopic rod 103. The first support frame 105 is rotatably mounted on the first support base 102 to support the component 4 to be welded. The telescopic rod 103 is mounted on the first support base 102 through the telescopic rod support 101, and the telescopic end of the telescopic rod 103 is connected to the first support frame 105 to adjust the angle of the segment of the component 4 to be welded where the welding carriage is located until it is horizontal, based on the feedback of the welding carriage.

[0034] It is understood that the first support frame 105 can be rotatably connected to the first support seat 102 via a pin. The first support frame 105 supports the component 4 to be welded. The first support seat 102 can be placed on the ground or a platform. The telescopic rod 103 can be connected to the first support frame 105 via a connecting seat. The telescopic rod 103 can be rotatably connected to the connecting seat via a pin. The telescopic rod 103 is a hydraulic telescopic rod. The hydraulic pump 109 inputs hydraulic oil through the hydraulic pipe 110 to drive the hydraulic telescopic rod. A power supply 206 can also be set on the trolley body 205. Of course, the power supply 206 can also be not on the trolley body 205. The power supply 206 forms a first control circuit with the first mercury switch 203, the first adjustment circuit and the hydraulic pump 109. The power supply 206 forms a second control circuit with the second mercury switch 204, the second adjustment circuit and the hydraulic pump 109. The extension and retraction of the telescopic end of the hydraulic telescopic rod are controlled by the first control circuit and the second control circuit to adjust the tilt angle of the first support frame 105, thereby adjusting the tilt angle of the component 4 to be welded.

[0035] Please see Figure 3 In some embodiments, the first support frame 105 includes two limiting plates, a support plate and a connecting plate. The two limiting plates are assembled on the same side of the support plate to form a support space for supporting the component 4 to be welded. The support plate is rotatably connected to the first support seat 102, and the connecting plate is connected to the support plate for connecting to the telescopic end of the telescopic rod 103.

[0036] It is known that the limiting plate and the support plate can form a rectangular support space. The shape of this support space is to adapt to the shape of the component 4 to be welded. The first support frame 105 of this structure facilitates the fixing of the telescopic rod 103, and also facilitates the limiting support of the component 4 to be welded.

[0037] Please continue reading. Figure 3 In some embodiments, the first support base 102 includes a rotating plate, a horizontal plate, and a support leg. The rotating plate is connected to the horizontal plate, and the support plate is rotatably connected to the rotating plate. The support leg is connected to the horizontal plate.

[0038] In this embodiment, there can be two support legs, which are arranged vertically and symmetrically at both ends of the horizontal plate. The rotating plate can also be vertically connected to the horizontal plate. The first support seat 102 of this structure is simple and can save overall costs.

[0039] Please see Figure 3 In some embodiments, the second support includes a second support frame 107 and a second support base 106. The second support frame 107 is rotatably mounted on the second support base 106 to support the component 4 to be welded and to rotate with the component 4 to be welded.

[0040] It is understandable that the structure of the second support 107, the second support base 106, and the second support frame can be referenced to the first support base 102 and the first support frame 105. The structure of the second support base is simple and saves costs.

[0041] Please see Figure 3 In some embodiments, the welding device for the bending and twisting box body also includes a base plate 3, and the adjusting jig 2 is mounted on the base plate 3.

[0042] It is known that the first and second support seats of the adjusting frame 2 can be welded to the base plate 3, thereby facilitating the overall handling of the welding device for the weld seam.

[0043] As can be seen from the above description, the welding device for the bending and twisting box body provided by the present invention can adjust the section of the component 4 to be welded, where the welding carriage 2 is located, to be horizontal, that is, parallel to the ground plane. On the one hand, it avoids the molten metal generated by the welding wire from flowing out of the weld, thus improving the overall welding quality and the aesthetics of the weld. On the other hand, it can also prevent the welding carriage 2 from falling off the component 4 to be welded.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
