DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0027] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] As described in the background technology, when welding the sheet after roll bending in the scheme of the related technology, the sheet may rebound; especially for thinner sheets (thickness less than 0.15mm), the probability of rebound after roll bending is relatively high. After the sheet rebounds, the sheet at the position to be welded cannot be aligned because it is not in the same plane, which affects the welding quality. After research, it was found that the reason for the above problem is that the extrusion roller in the related technology can only limit the two sides of the sheet after roll bending, but cannot limit the upper and lower ends of the sheet. In order to facilitate subsequent welding, the position of the sheet to be welded is generally set at the upper end. Therefore, when the sheet rebounds, the sheet at the position to be welded will have a height difference, which affects the welding quality.

[0029] In view of this, the embodiment of the present application aims to provide a welding auxiliary device and a welding system, by setting a relative first limiting mechanism and a second limiting mechanism, the first limiting groove of the first limiting mechanism limits the position to be welded of the sheet after roll bending, the second limiting groove of the second limiting mechanism limits the bottom surface of the sheet after roll bending, and the welding device is used to weld the sheet through the welding notch on the first limiting mechanism. Due to the effects of the first limiting groove and the second limiting groove, the probability of springback of the sheet after roll bending is reduced, so that the staggered layer of the sheet at the position to be welded is kept within a reasonable range, which is conducive to ensuring the welding quality.

[0030] The contents of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application in more detail. It should be noted that in the present embodiment, the first direction X, the second direction Y and the third direction Z are three different directions in a three-dimensional space. For example, the first direction X, the second direction Y and the third direction Z are perpendicular to each other, and the third direction Z can be, for example, the forward direction of the sheet 1 after roll bending.

[0031] Please refer to Figure 1-Figure 6, this embodiment provides a welding auxiliary device 10, comprising a first limiting mechanism 100 and a second limiting mechanism 200 arranged relatively along a first direction X. Among them, the first limiting mechanism 100 is provided with a first limiting groove 101 on the side facing the second limiting mechanism 200, and the first limiting groove 101 is used to limit the position to be welded of the plate 1 after roll bending. It can be understood that the shape of the first limiting groove 101 is adapted to the shape of the position to be welded of the plate 1 after roll bending, and in the plane perpendicular to the third direction Z, the projection of the first limiting groove 101 can be, for example, square or arc-shaped. In this embodiment, the first limiting mechanism 100 can limit and adjust the position to be welded of the plate 1 after roll bending and the two side surfaces close to the position to be welded. The second limiting mechanism 200 is provided with a second limiting groove 201 on the side facing the first limiting mechanism 100, and the second limiting groove 201 is used to limit the bottom surface of the plate 1 after roll bending. It is understandable that the shape of the second limiting groove 201 is adapted to the outer shape of the bottom surface of the sheet 1 after roll bending, and the projection of the second limiting groove 201 in the plane perpendicular to the third direction Z may also be, for example, square or arc-shaped. In this embodiment, the second limiting mechanism 200 can limit and adjust the bottom surface of the sheet 1 after roll bending and the two side surfaces close to the bottom surface, mainly playing the role of auxiliary adjustment.

[0032] It can be seen from the above description that in this embodiment, the first limiting groove 101 is used to limit the position to be welded of the sheet 1 after roll bending, and the second limiting groove 201 is used to limit the bottom surface of the sheet 1 after roll bending. Due to the effects of the first limiting groove 101 and the second limiting groove 201, the probability of springback of the sheet 1 after roll bending is reduced, so that the staggered layer of the sheet at the position to be welded is kept within a reasonable range, which is conducive to ensuring the welding quality.

[0033] In this embodiment, the first limiting mechanism 100 and the second limiting mechanism 200 can be installed on the same part, or the first limiting mechanism 100 and the second limiting mechanism 200 can be installed on different parts, which can be specifically configured according to needs.

[0034] For example, the welding auxiliary device 10 of this embodiment further includes a mounting bracket, which includes a first mounting plate 310 and a second mounting plate 320. The first mounting plate 310 is used to connect to the ground, and the first mounting plate 310 can be fixed to the ground by bolts, for example. The second mounting plate 320 is vertically arranged on the first mounting plate 310, and the second mounting plate 320 and the first mounting plate 310 can also be connected by bolts, for example. The first limiting mechanism 100 and the second limiting mechanism 200 can both be fixed on the second mounting plate 320.

[0035] Please continue to refer to Figure 2-Figure 4In this embodiment, the first limiting mechanism 100 includes a first limiting block 110, and a first adjusting block 120 and a second adjusting block 130 are arranged on one side of the first limiting block 110 facing the second limiting mechanism 200. The first adjusting block 120 and the second adjusting block 130 are arranged at intervals along the second direction Y. The first limiting block 110, the first adjusting block 120 and the second adjusting block 130 jointly surround the first limiting groove 101. It can be understood from the accompanying drawings that the first limiting groove 101 forms openings on both sides of the third direction Z so that the sheet 1 after roll bending can pass through. The first limiting block 110 forms the bottom wall of the first limiting groove 101, and the first adjusting block 120 and the second adjusting block 130 respectively form two side walls of the first limiting groove 101. In this embodiment, the first adjusting block 120 and the second adjusting block 130 are both slidably arranged on the first limiting block 110 along the second direction Y, so as to facilitate adjusting the positions of the first adjusting block 120 and the second adjusting block 130 in the second direction Y according to the size of the sheet 1 after roll bending.

[0036] Exemplarily, the first limit block 110 of this embodiment is provided with a first adjustment mechanism and a second adjustment mechanism on both sides along the second direction Y. The first adjustment mechanism is connected to the first adjustment block 120 and can drive the first adjustment block 120 to slide on the first limit block 110 to adjust the position of the first adjustment block 120 in the second direction Y. The second adjustment mechanism is connected to the second adjustment block 130 and can drive the second adjustment block 130 to slide on the first limit block 110 to adjust the position of the second adjustment block 130 in the second direction Y.

[0037] Specifically, the first adjustment mechanism of the present embodiment includes a first fixed seat 121 and a first adjustment rod 122. The first fixed seat 121 is fixed to one side of the first limit block 110 along the second direction Y. The first fixed seat 121 and the first limit block 110 can be fixed, for example, by welding, screwing, etc. The first adjustment rod 122 is rotatably arranged in the first fixed seat 121; illustratively, a corresponding mounting groove may be provided on the first fixed seat 121, and two flanges are provided on the first adjustment rod 122, and the two flanges are respectively clamped on the two sides of the mounting groove, so as to ensure that the first adjustment rod 122 and the first fixed seat 121 can rotate relative to each other. The first adjustment block 120 is provided with a first adjustment hole, and the first adjustment hole may be a threaded hole. The first adjustment rod 122 is threadedly connected to the first adjustment hole. By rotating the first adjustment rod 122, the first adjustment block 120 can slide along the second direction Y (for example, rotating the first adjustment rod 122 clockwise can make the first adjustment block 120 move toward the second direction Y). Figure 4 The first adjusting rod 122 is rotated counterclockwise to allow the first adjusting block 120 to move in the second direction Y toward Figure 4 The first adjusting block 120 is moved to the right side as shown in the figure, thereby changing the position of the first adjusting block 120 to clamp the sheet 1 after roll bending to prevent its rebound deformation.

[0038] Similarly, the second adjustment mechanism includes a second fixing seat 131 and a second adjustment rod 132. The second fixing seat 131 is fixed to the other side of the first limit block 110 along the second direction Y. The second fixing seat 131 and the first limit block 110 can be fixed, for example, by welding, screwing, etc. The second adjustment rod 132 is rotatably arranged in the second fixing seat 131; illustratively, a corresponding mounting groove can be provided on the second fixing seat 131, and two flanges are provided on the second adjustment rod 132. The two flanges are respectively clamped on the two sides of the mounting groove, so as to ensure that the second adjustment rod 132 and the second fixing seat 131 can rotate relative to each other. The second adjustment block 130 is provided with a second adjustment hole, and the second adjustment hole can be a threaded hole. The second adjustment rod 132 is threadedly connected to the second adjustment hole. By rotating the second adjustment rod 132, the second adjustment block 130 can slide along the second direction Y (for example, rotating the second adjustment rod 132 clockwise can make the second adjustment block 130 move toward the second direction Y). Figure 4 The second adjusting rod 132 is rotated counterclockwise to allow the second adjusting block 130 to move in the second direction Y toward Figure 4 The left side slides as shown in the figure), thereby changing the position of the second adjusting block 130 to clamp the sheet 1 after roll bending to prevent its rebound deformation.

[0039] Furthermore, in order to ensure that the first adjustment block 120 and the second adjustment block 130 do not deviate during the movement, the first limit block 110 of this embodiment is provided with a first guide plate 141 and a second guide plate 142 on both sides along the third direction Z. The first guide plate 141 includes a first connecting section 1411 and a first guide section 1412, the first guide section 1412 is perpendicular to the first connecting section 1411, and the first connecting section 1411 and the first guide section 1412 are substantially "L" shaped. The second guide plate 142 includes a second connecting section 1421 and a second guide section 1422, the second guide section 1422 is perpendicular to the second connecting section 1421, and the second connecting section 1421 and the second guide section 1422 are substantially "L" shaped. The first connecting section 1411 and the second connecting section 1421 are respectively fixedly connected to both sides of the first limit block 110 along the third direction Z, for example, they can be fixed by welding, bolting, etc. The first guide section 1412 and the second guide section 1422 are located on the side of the first limit block 110 facing the second limit mechanism 200, and a gap is formed between the first guide section 1412 and the second guide section 1422 and the first limit block 110. The first adjustment block 120 and the second adjustment block 130 are both located between the first guide section 1412 and the second guide section 1422 and the first limit block 110, so that they can move along the second direction Y under the guidance of the first limit block 110, the first guide plate 141 and the second guide plate 142. In this embodiment, the first guide plate 141 includes two first guide sections 1412, which are arranged at intervals along the second direction Y, and the second guide plate 142 includes two second guide sections 1422, which are arranged at intervals along the second direction Y, so as to avoid blocking the opening of the first limit slot 101 in the third direction Z.

[0040] In this embodiment, the first limiting mechanism 100 is further provided with a welding notch 102, and the welding notch 102 is connected to the first limiting groove 101. When in use, the external welding device can weld the to-be-welded position of the sheet 1 after roll-bending through the welding notch 102, thereby obtaining the desired product. Exemplarily, the welding notch 102 can be provided on the first limiting block 110, and the welding notch 102 passes through the first limiting block 110 along the first direction X, so as to facilitate the welding device to be inserted into the first limiting groove 101.

It is understandable that the plurality of negative pressure holes 103 can be connected to the bottom wall of the first limiting groove 101, and the plurality of negative pressure holes 103 form negative pressure through an external negative pressure source, so that the position to be welded of the sheet 1 after roll bending can be adsorbed on the bottom wall of the first limiting groove 101 by the action of negative pressure, ensuring that the sheet at the position to be welded is always in contact with the bottom wall of the first limiting groove 101, avoiding the occurrence of misalignment of the sheet at the position to be welded, thereby facilitating improving the welding quality.

[0042] In a possible implementation, the first limit block 110 of the present embodiment can be a metal block, such as a copper block, so as to ensure that the welding position has a good thermal conductivity. A ceramic plate 150 is also provided on the side of the first limit block 110 facing the second limit mechanism 200, and the ceramic plate 150 is located in the first limit groove 101. In other words, the ceramic plate 150 is in direct contact with the plate 1 after roll bending. By providing the ceramic plate 150, the wear resistance can be improved, which is beneficial to prolonging the service life. The above-mentioned multiple negative pressure holes 103 can be opened on the ceramic plate 150.

[0043] Furthermore, in order to reduce the heat accumulation in the first limit block 110 and improve the heat dissipation efficiency of the first limit block 110, the present embodiment further provides a coolant pipeline in the first limit block 110, and a coolant inlet 111 and a coolant outlet 112 are provided on the surface of the first limit block 110.

Exemplarily, along the first direction X, a mounting groove 321 is formed at one end of the second mounting plate 320 away from the first mounting plate 310, and the first limiting mechanism 100 further includes a mounting seat 160 and a limiting seat 170, and the two ends of the mounting seat 160 along the second direction Y are respectively connected to the first limiting block 110 and the limiting seat 170, and the mounting seat 160 is slidably disposed in the mounting groove 321.

[0045] In a possible implementation, the end of the second mounting plate 320 of this embodiment away from the first mounting plate 310 is further connected to a fixing plate 330 and a third adjustment rod 340, the fixing plate 330 is provided with a third adjustment hole, the third adjustment hole can be a threaded hole, the third adjustment rod 340 is passed through the third adjustment hole and is threadedly connected to the third adjustment hole. A connecting groove 1601 is further provided in the mounting seat 160, and the third adjustment rod 340 is fixedly connected to the connecting groove 1601. Through the above structure, the third adjustment rod 340 can be rotated to drive the first limiting mechanism 100 to move along the first direction X.

The body 161, the guide portion 162 and the limiting seat 170 together form a guide groove, and one end of the second mounting plate 320 away from the first mounting plate 310 is inserted into the guide groove. Through the above structure, the first limiting mechanism 100 can be guided when moving along the first direction X by using the cooperation of the guide groove and the second mounting plate 320.

[0047] In this embodiment, a limiting groove is further provided on the side of the limiting seat 170 facing the second mounting plate 320, and a pressing block 171 is provided in the limiting groove. The limiting seat 170 is also provided with an abutment member, which passes through the limiting seat 170 and is connected to the pressing block 171.
