[0056] In this embodiment of the disclosure, such as Figure 1 As shown, the first clamping mechanism 2 is located below the connecting platform on the first fixed rod 102. The first welding assembly 501 is made of stainless steel or carbon steel and has a cuboid frame structure with four faces: top, bottom, and two side faces. The top face is placed face down between the first fixed rod 102 and the second fixed rod 103. The first clamping mechanism 2 provides a first clamping force to one side of the first welding assembly 501. The direction of the first clamping force is from the first clamping mechanism 2 on the first fixed rod 102 horizontally to the second fixed rod 103.

The second clamping mechanism 3 is used to provide a second clamping force to the other side of the first welding assembly 501. The direction of the first clamping force is opposite to the direction of the second clamping force.

[0058] In this embodiment of the disclosure, such as Figure 1 As shown, the second clamping mechanism 3 is located below the connecting platform on the second fixed rod 103, at the same horizontal height as the first clamping mechanism 2. The second clamping mechanism 3 provides a second clamping force to the other side of the first welding assembly 501. The direction of the second clamping force is from the second clamping mechanism 3 on the second fixed rod 103 horizontally towards the first fixed rod 102. Optionally, there can be two second clamping mechanisms 3, respectively located on two flat rod-shaped structures of the second fixed rod 103, at the same horizontal height.

[0059] The first support mechanism 4 is fixed to the top of the third fixing rod 104, and the first support mechanism 4 is used to support the bottom inner wall of the first welding assembly 501.

[0060] In this embodiment of the disclosure, such as Figure 1 As shown, the top of the two pairs of flat rod-shaped structures of the first support mechanism 4 and the third fixed rod 104 are fixedly connected. The height of the first support mechanism 4 is less than the height of the bottom of the first welding assembly 501 after it is placed in the welding positioning equipment. The first support mechanism 4 is used to support the bottom inner wall of the first welding assembly 501.

[0061] In an optional embodiment, the first support mechanism 4 includes a support plate 401, a first support member 402, and a second support member 403.

[0062] In this embodiment of the disclosure, such as Figure 2 As shown, the support plate 401 is a rectangular flat plate structure, and its length is approximately equal to the distance between the two sides of the first welding assembly 501. Optionally, the support plate 401 can be a hollow structure, with multiple elliptical holes in the middle of the support plate 401 to save manufacturing materials and reduce manufacturing costs. The first support member 402 and the second support member 403 are disposed at both ends of the support plate 401.

[0063] The side of the support plate 401 is fixed to the top of the third fixing rod 104.

[0064] In this embodiment of the disclosure, such as Figure 2 As shown, one side of the support plate 401 is fixed to the top of the third fixing rod 104 by screws or by welding.

[0065] The first support member 402 is disposed at one end of the support plate 401. The first support member 402 is used to support the inner wall of the first bending part of the first welding assembly 501. The first bending part is the connection between the bottom and one side of the first welding assembly 501.

[0066] In this embodiment of the disclosure, such as Figure 2 As shown, a first support member 402 is disposed at one end of the support plate 401 near the first fixed rod 102. The first support member 402 is used to support the inner wall of the first bent portion of the first welding assembly 501. The first bent portion is the connection point between the bottom of the first welding assembly 501 and the side near the first fixed rod 102, and this connection point has an arc-shaped structure. Optionally, the shape of the first support member 402 matches the shape of the inner wall of the first bent portion, and the length of the first support member 402 is approximately equal to the width of the first bent portion of the first welding assembly 501.

[0067] The second support member 403 is disposed at the other end of the support plate 401, and the first support member 402 is used to support the inner wall of the second bend of the first welding assembly 501. The second bend is the connection between the bottom of the first welding assembly 501 and the other side.

[0068] In this embodiment of the disclosure, such as Figure 2As shown, the second support member 403 is disposed at one end of the support plate 401 near the second fixing rod 103. The second support member 403 is used to support the inner wall of the second bend of the first welding assembly 501. The second bend is the connection point between the bottom of the first welding assembly 501 and the side near the second fixing rod 103, and this connection point has an arc-shaped structure. Optionally, the shape of the second support member 403 matches the shape of the inner wall of the second bend, and the length of the second support member 403 is approximately equal to the width of the second bend of the first welding assembly 501. Optionally, the first support member 402 and the second support member 403 can be fixed to the support plate 401 by welding, or the first support member 402, the second support member 403, and the support plate 401 can be integrally formed.

[0069] Based on the above, in this embodiment of the present disclosure, by setting the first support member 402 at one end of the support plate 401, the inner wall of the first bending part of the first welding assembly 501 can be supported; by setting the second support member 403 at the other end of the support plate 401, the inner wall of the second bending part of the first welding assembly 501 can be supported. Through the above settings, the welding positioning structure can support both ends of the bottom inner wall of the first welding assembly 501, making the fixed support and positioning of the first welding assembly 501 more secure and reducing the possible displacement of the first welding assembly 501 during the welding process.

[0070] In an optional embodiment, the first clamping mechanism 2 includes a first clamping member 201 that moves in a direction perpendicular to the side of the first welding assembly 501 and is used to apply a first clamping force to the outer wall of the first bend.

[0071] In this embodiment of the disclosure, such as Figure 2 As shown, the first clamping mechanism 2 consists of a first fixing member, a first telescopic member, and a first clamping member 201 movably connected to the first fixing member. The first fixing member is fixed below the connecting platform of the first fixing rod 102. The first clamping member 201 is fixedly connected to the first telescopic member, which is sleeved inside the first fixing member. The first telescopic member can be electrically driven to move the first clamping member 201 in a direction perpendicular to the side of the first welding assembly 501. The first clamping member 201 is used to apply a first clamping force to the outer wall of the first bending part. Optionally, the shape of the first clamping member 201 matches the shape of the outer wall of the first bending part.

[0072] The second clamping mechanism 3 includes a second clamping member 301, which moves in a direction perpendicular to the side of the first welding assembly 501. The second clamping member 301 is used to apply a second clamping force to the outer wall of the second bending portion.

[0073] In this embodiment of the disclosure, such as Figure 2As shown, the second clamping mechanism 3 consists of a second fixing member, a second telescopic member, and a second clamping member 301 movably connected to the second fixing member. The second fixing member is fixed below the connecting platform of the second fixing rod 103. The second clamping member 301 is fixedly connected to the second telescopic member, which is sleeved inside the second fixing member. The second telescopic member can be electrically driven to move the second clamping member 301 in a direction perpendicular to the side of the first welding assembly 501. The second clamping member 301 is used to apply a second clamping force to the outer wall of the second bending portion. Optionally, the shape of the second clamping member 301 matches the shape of the outer wall of the second bending portion. Optionally, the moving direction of the second clamping member 301 is on the same straight line as the moving direction of the first clamping member 201. When there are multiple second clamping members 301 and multiple first clamping members 201, the number of second clamping members 301 and first clamping members 201 is the same, and the second clamping members 301 and the first clamping members 201 are set in a one-to-one correspondence. The moving direction of each second clamping member 301 is on the same straight line as the moving direction of the corresponding first clamping member 201.

[0074] Based on the above, in this embodiment of the present disclosure, the first clamping member 201 of the first clamping mechanism 2 can flexibly apply a first clamping force in a direction perpendicular to the side of the first welding assembly 501; the second clamping member 301 of the second clamping mechanism 3 can flexibly apply a second clamping force in a direction perpendicular to the other side of the first welding assembly 501; the first clamping force and the second clamping force can make the fixing and positioning of the first welding assembly 501 more reliable.

[0075] In an optional embodiment, the welding positioning device further includes a positioning mechanism 6, which is fixed to the first support mechanism 4 and is used to fix the second welding assembly 502, which is welded to the bottom of the first welding assembly 501.

[0076] In this embodiment of the disclosure, such as Figure 1 As shown, the positioning mechanism 6 includes two back plates and two side plates. The two back plates are fixed to the side plates of the first support mechanism 4 and the third fixing rod 104. Each back plate is connected to a side plate, which is rectangular in structure. The two side plates are arranged parallel to each other in the horizontal direction, and the short side of the rectangular structure of the side plate is fixedly connected to the corresponding back plate. The positioning mechanism 6 is used to fix the second welding assembly 502, which is made of stainless steel or carbon steel. Optionally, the positioning mechanism 6 fixes the second welding assembly 502 by providing a slot on the inner side of each back plate to accommodate the side of the second welding assembly 502. The shape of the slot matches the shape of the side of the second welding assembly 502, and the second welding assembly 502 is welded to the bottom of the first welding assembly 501.

[0077] As can be seen from the above, in this embodiment of the present disclosure, the positioning mechanism 6 fixed on the first support mechanism 4 can realize the positioning and fixing of the second welding component 502, which facilitates the bottom welding of the second welding component 502 and the first welding component 501.

[0078] In an optional embodiment, a third pressing mechanism 7 is provided on both sides of the positioning mechanism 6. The third pressing mechanism 7 is used to provide a third pressing force to the second welding assembly 502. The third pressing force is used to press the bottom of the second welding assembly 502 and the first welding assembly 501.

[0079] In this embodiment of the disclosure, such as Figure 1 As shown, the third clamping mechanism 7 is respectively disposed on the outer side of the side plate of the positioning mechanism 6. The third clamping mechanisms 7 on both sides are located at the same horizontal height. The third clamping mechanism 7 is used to provide a third clamping force to the second welding assembly 502. The third clamping force is used to clamp the bottom of the second welding assembly 502 and the first welding assembly 501. The direction of the third clamping force is perpendicular to the bottom of the first welding assembly 501. Optionally, there can be two third clamping mechanisms 7 on each side, which are disposed adjacently on the outer side of the back plate of the positioning mechanism 6. The two third clamping mechanisms 7 are located at the same horizontal height.

[0080] As can be seen from the above, in this embodiment of the present disclosure, by providing third pressing mechanisms 7 on both sides of the positioning mechanism 6, pressing force can be applied to both sides of the second welding component 502 to fix and position the second welding component 502, preventing the second welding component 502 from shaking during the welding process, which is beneficial to ensuring the accuracy of welding.

[0081] In an optional embodiment, each third clamping mechanism 7 includes a third clamping member 701 that moves in a direction perpendicular to the second welding assembly 502 and is used to apply a third clamping force to the side of the second welding assembly 502.

[0082] In this embodiment of the disclosure, such as Figure 2As shown, the third clamping mechanism 7 consists of a third fixed member, a third telescopic member, and a third clamping member 701 movably connected to the third fixed member. The third fixed member is fixed to the outside of the side plate of the positioning mechanism 6. The third clamping member 701 is fixedly connected to the third telescopic member, which is sleeved inside the third fixed member. The third clamping member 701 can be electrically driven to move in a direction perpendicular to the second welding assembly 502. The third clamping member 701 applies a third clamping force to the side of the second welding assembly 502. Optionally, the shape of the third clamping member 701 matches the shape of the side of the second welding assembly 502. Optionally, the moving directions of each third clamping member 701 are parallel to each other. When there are multiple third clamping members 701 on both sides, the number of third clamping members 701 on each side is the same, and the third clamping members 701 on both sides are arranged in a one-to-one correspondence.

[0083] Based on the above, in this embodiment of the present disclosure, the third clamping member 701 of the third clamping mechanism 7 can flexibly apply a third clamping force in a direction perpendicular to the second welding assembly 502; by applying the third clamping force to both sides of the second welding assembly 502 simultaneously through the third clamping members 701 on both sides, the fixing and positioning between the welding surface of the second welding assembly 502 and the welding surface of the first welding assembly 501 can be made more reliable.

[0084] In an optional embodiment, the welding positioning device further includes a fourth clamping mechanism 8 and a fifth clamping mechanism 9.

[0085] In this embodiment of the disclosure, such as Figure 1 As shown, both the fourth clamping mechanism 8 and the fifth clamping mechanism 9 can be made of metal.

[0086] The fourth clamping mechanism 8 is disposed on the top of the first fixed rod 102. The fourth clamping mechanism 8 is used to provide a fourth clamping force to the first welding assembly 501. The angle between the direction of the fourth clamping force and the vertical direction is an acute angle.

[0087] In this embodiment of the disclosure, such as Figure 1 As shown, the fourth clamping mechanism 8 is located above the connecting platform on the first fixed rod 102, i.e., at the top of the first fixed rod 102. The height of the fourth clamping mechanism 8 is higher than the height of the bottom of the first welding assembly 501. The fourth clamping mechanism 8 is used to provide a fourth clamping force to the outer wall of the position where the bottom of the first welding assembly 501 meets the first bend.

Optionally, there can be two fifth clamping mechanisms 9, respectively located on two flat rod-shaped structures of the second fixed rod 103, with the two fifth clamping mechanisms 9 at the same horizontal height.

[0090] As can be seen from the above, in this embodiment of the present disclosure, by setting a fourth pressing mechanism 8 and a fifth pressing mechanism 9 on the top of the first fixing rod 102 and the second fixing rod 103 respectively, a pressing force can be applied to both sides of the bottom of the first welding component 501 to fix and position the second welding component 502, preventing the first welding component 501 from shaking during the welding process, which is beneficial to ensuring the accuracy of welding.

[0091] In an optional embodiment, the fourth clamping mechanism 8 includes a fourth clamping member 801, the width of which matches the bottom width of the first welding assembly 501, and the fourth clamping member 801 is used to apply a fourth clamping force to the bottom of the first welding assembly 501.

It can be electrically driven to apply a fourth clamping force to the bottom of the first welding assembly 501 via the fourth clamping member 801. The width of the fourth clamping member 801 matches the bottom width of the first welding assembly 501.

[0093] The fifth clamping mechanism 9 includes a fifth clamping member 901, the width of which matches the bottom width of the first welding assembly 501. The fifth clamping member 901 is used to apply a fifth clamping force to the bottom of the first welding assembly 501.

[0094] In this embodiment of the disclosure, such as Figure 2As shown, the fifth clamping mechanism 9 consists of a fourth fixing member, a fifth telescopic member, and a fifth clamping member 901 movably connected to the fifth fixing member. The fifth fixing member is fixed above the connecting platform of the second fixing rod 103. The fifth clamping member 901 is fixedly connected to the fifth telescopic member, which is sleeved inside the fifth fixing member. It can be electrically driven to apply a fifth clamping force to the bottom of the first welding assembly 501 via the fifth clamping member 901. The width of the fifth clamping member 901 matches the bottom width of the first welding assembly 501.

[0095] Based on the above, in this embodiment of the present disclosure, the fourth clamping member 801 of the fourth clamping mechanism 8 and the fifth clamping member 901 of the fifth clamping mechanism 9 can apply a downward-sloping fourth and fifth clamping force to the bottom of the first welding assembly 501; the above-mentioned fourth and fifth clamping forces can make the fixation and positioning of the bottom of the first welding assembly 501 more reliable.

[0096] In an optional embodiment, the welding positioning device further includes at least two second support mechanisms 10, which are disposed on the top plate 101 and are used to support the top of the first welding assembly 501.

[0097] In this embodiment of the disclosure, such as Figure 1 As shown, the second support mechanisms 10 are arranged in pairs on the top plate 101, with each pair of second support mechanisms 10 correspondingly arranged on both sides of the top plate 101. All second support mechanisms 10 are located at the same horizontal height and are used to support the top of the first welding assembly 501. Optionally, there can be two pairs of second support mechanisms 10, one pair located at the corresponding position at the front end of the top of the first welding assembly 501, and the other pair located at the corresponding position at the rear end of the top of the first welding assembly 501.

[0098] As can be seen from the above, in this embodiment of the present disclosure, by providing at least two second support mechanisms 10 on the top plate 101, the top of the first welding component 501 can be supported to fix and position the first welding component 501 from the top, preventing the second welding component 502 from shaking during the welding process, which is beneficial to ensuring the accuracy of welding.

[0099] In an optional embodiment, the second support mechanism 10 includes a third support member 1001, which moves in a direction perpendicular to the top plate 101. The third support member 1001 is used to support the third bend of the first welding assembly 501, which is the connection between the top and the side of the first welding assembly 501.

[0100] In this embodiment of the disclosure, such as Figure 2As shown, the second support mechanism 10 consists of a sixth fixing member, a sixth telescopic member, and a third support member 1001 movably connected to the sixth fixing member. The sixth fixing member is fixed to the outside of the side plate of the positioning mechanism 6. The third support member 1001 is fixedly connected to the sixth telescopic member, which is sleeved inside the sixth fixing member and passes through a corresponding hole on the top plate 101 to connect with the third support member 1001. The third support member 1001 can be electrically driven to move in a direction perpendicular to the top of the first welding assembly 501. The third support member 1001 is used to support the third bent portion of the first welding assembly 501, which is the connection point between the top and the side of the first welding assembly 501. Optionally, the shape of the third support member 1001 matches the shape of the outer wall of the third bent portion of the first welding assembly 501. Optionally, each of the second support mechanisms 10 is respectively arranged on both sides of the top of the first welding assembly 501. When there are multiple third support members 1001 on both sides, the number of third support members 1001 on each side is the same, and the third support members 1001 on both sides are arranged one-to-one.

[0101] Based on the above, in this embodiment of the present disclosure, the third support member 1001 of the second support mechanism 10 can provide support force to the connection between the top and side of the first welding assembly 501 in a direction perpendicular to the top of the first welding assembly 501; by providing support force to both sides of the top of the first welding assembly 501 through the aforementioned third support members 1001 on both sides, the fixing and positioning of the top of the first welding assembly 501 can be made more reliable.

[0102] In the above embodiments, this disclosure provides a welding positioning device. Compared with other welding positioning devices, in this embodiment, by using the first support member 402 and the second support member 403, the inner walls of the two bent portions at the bottom of the first welding assembly 501 can be supported; by using the first pressing member 201 of the first pressing mechanism 2 and the second pressing member 301 of the second pressing mechanism 3, a pressing force can be flexibly applied in a direction perpendicular to the side of the first welding assembly 501; by using the positioning mechanism 6 fixed on the first support mechanism 4, the second welding assembly 502 can be positioned and fixed, facilitating the welding of the second welding assembly 502 to the bottom of the first welding assembly 501; by using the third pressing member 701 of the third pressing mechanism 7, the second welding assembly 502 can be positioned and fixed to the bottom of the first welding assembly 501; and by using the third pressing member 701 of the third pressing mechanism 7, the second welding assembly 502 can be positioned and fixed to the bottom of the first welding assembly 501. A clamping force is flexibly applied in a direction perpendicular to the plane of the second welding component 502 to fix and position the welding surface of the second welding component 502 and the welding surface of the first welding component 501. Through the fourth clamping member 801 of the fourth clamping mechanism 8 and the fifth clamping member 901 of the fifth clamping mechanism 9, a fourth and fifth clamping force obliquely downward can be applied to the bottom of the first welding component 501, making the fixation and positioning of the bottom of the first welding component 501 more reliable. Through the third support member 1001 of the second support mechanism 10, support force can be provided to the top two sides of the first welding component 501, making the fixation and positioning of the top of the first welding component 501 more reliable.

[0103] In one specific embodiment, the technical solution implementation process of this application is as follows: The first welding component 501 is placed upside down on the first support mechanism 4, and the first welding component 502 is placed in the positioning mechanism 6 for positioning. Then, the welding positioning device starts to operate. The third clamping member 701 of the third clamping mechanism 7 presses down to fix the first welding component 502. The fourth clamping member 801 of the fourth clamping mechanism 8 and the fifth clamping member 901 of the fifth clamping mechanism 9 press down simultaneously and then release the pressure (relieve the cylinder pressure). Then, the third support member 1001 of the second support mechanism 10 presses up. The first clamping member 201 of the first clamping mechanism 2 and the second clamping member 301 of the second clamping mechanism 3 press inward simultaneously. Finally, the fourth clamping member 801 of the fourth clamping mechanism 8 and the fifth clamping member 901 of the fifth clamping mechanism 9 press down simultaneously (hold pressure). After that, laser welding is performed.
