Description

Technical Field

[0001] This utility model relates to the field of space frame welding equipment technology, specifically a continuous mold for welding metal space frames. Background Technology

[0002] Resistance spot welding is a common processing step in the production of metal mesh frames. The common welding equipment is a single-point welding device. During the production process, the production personnel place the connection points of the metal wires one by one under the welding electrode and use the welding electrode to weld the connection points one by one.

[0003] A search revealed Chinese Patent Publication No. CN 221870807 U, which discloses a metal mesh frame welding device. The device includes a base plate with four symmetrically arranged mounting seats on its top. Each mounting seat is connected to a driving device, and a rectangular block is connected to each driving device. A bearing plate is fixedly mounted on the top of the rectangular block, and a second bearing plate is in close contact with the side wall of the first bearing plate. A hinge is fixedly mounted between the second and first bearing plates, and a limiting block is fixedly mounted on the bottom of the first bearing plate. This metal mesh frame welding device, through the interaction of components such as handles, round rods, limiting blocks, hinges, and springs, allows for free switching of the shape of the bearing plate to handle welding operations on metal mesh frames of different shapes. This reduces the time spent by workers constantly changing molds and also lowers the cost of mold usage.

[0004] The metal grid welding mold in the aforementioned patent still has some shortcomings. In the existing metal grid welding process, it is necessary to manually align the welding ball with multiple steel pipes before welding the grid. However, in actual manual operation, it is quite troublesome to align the angle between the steel pipe and the welding ball, and it is easy to have a large deviation. This makes it difficult to accurately align and weld the subsequent connecting pipes, which is very inconvenient for workers to weld the grid. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a continuous welding mold for metal space frames. This solves the problem that in the existing metal space frame welding process, manual alignment of the welding ball with multiple steel pipes is required before welding can be performed. However, in actual manual operation, aligning the angle between the steel pipes and the welding ball is troublesome and prone to significant deviations, making it difficult to accurately align and weld subsequent connecting pipes, which is very inconvenient for workers welding space frames.

[0006] This utility model provides the following technical solution: a continuous welding mold for metal mesh frame, including a welding support platform, with legs evenly arranged around the bottom of the welding support platform, each leg having a movable wheel at its bottom, a welding ball support module on the welding support platform, two steel pipe limiting modules symmetrically arranged on both sides of the welding support platform, a welding ball on the top of the welding support platform, and two mesh frame welding steel pipes symmetrically arranged on both sides of the welding ball;

[0007] The welding ball support module includes an abutment support seat disposed at the bottom of the welding ball. A lifting screw is rotatably connected to the bottom end of the abutment support seat. The bottom end of the lifting screw is threaded through the middle of the welding support platform. A rotating disk is disposed at the bottom end of the lifting screw. Two limiting rods are symmetrically disposed on both sides of the bottom end of the abutment support seat. The limiting rods pass through the welding support platform. A side support frame is disposed on the side of the welding support platform. An abutment screw is threaded through the top end of the side support frame. A top abutment plate is rotatably connected to the bottom end of the abutment screw.

[0008] The steel pipe limiting module includes two steel pipe support seats symmetrically arranged on both sides of the welding support platform. Each steel pipe support seat has a rotating groove at its top. A reverse screw is rotatably arranged in the rotating groove, and one end of the reverse screw rotates through the inner wall of the rotating groove.

[0009] Preferred technical solution 1: The end of the reverse screw is provided with a handle, and two drive sleeves are symmetrically sleeved on the reverse screw.

[0010] Preferred technical solution 2: The top of each drive screw sleeve is provided with a clamping connecting plate, and the side of the clamping connecting plate is provided with a fixing clamp.

[0011] Preferred technical solution 3: A limiting groove is formed on the bottom wall of the rotating groove, and a limiting block is provided at the bottom end of the driving screw sleeve. The limiting block is slidably inserted into the limiting groove.

[0012] This design allows the drive screw sleeve to slide within the limiting groove of the limiting block, preventing the drive screw sleeve from rotating as the reverse screw rotates.

[0013] Preferred technical solution four: The threads on both sides of the reverse screw shaft are in opposite directions, and the drive sleeves are all threadedly connected to the reverse screw shaft.

[0014] This design enables the two drive sleeves mounted on the reverse screw to move closer together when the reverse screw rotates.

[0015] Preferred technical solution five: The inner sidewall of the fixing clamp is an arc shape that fits into the welded steel pipe of the grid frame.

[0016] This solution enables the fixed clamping plate to clamp and support the welded steel pipe of the space frame under the push of the clamping connecting plate.

[0017] Compared with the prior art, this utility model provides a continuous die for welding metal grid structures, which has the following advantages:

[0018] (1) This utility model provides a welding ball support module and a steel pipe limiting module on the welding support platform. The abutment support seat in the welding ball support module can support the bottom of the welding ball under the rotation of the lifting screw, while the top abutment plate can fix the welding ball above the welding support platform in conjunction with the abutment support seat under the rotation of the abutment screw. The fixing clamp in the steel pipe limiting module can fix the welded steel pipe of the space frame and the welding ball after they are aligned and stably fixed under the rotation of the reverse screw. This makes the welding between the welding ball and the welded steel pipe of the space frame more precise and prevents large deviations, making it more convenient for users to use.

[0026] Please see Figure 1-4 ,

[0027] Example 1: A continuous welding mold for metal mesh frame includes a welding support platform 1, with legs 2 evenly arranged around the bottom of the welding support platform 1, and each leg 2 having a movable wheel 3 at its bottom. A welding ball support module 4 is arranged on the welding support platform 1, and two steel pipe limiting modules 5 are symmetrically arranged on both sides of the welding support platform 1. A welding ball 6 is arranged on the top of the welding support platform 1, and two mesh frame welding steel pipes 7 are symmetrically arranged on both sides of the welding ball 6.

[0028] The welding ball support module 4 includes an abutment support seat 401 disposed at the bottom of the welding ball 6. A lifting screw 402 is rotatably connected to the bottom end of the abutment support seat 401. The bottom end of the lifting screw 402 is threaded through the middle of the welding support platform 1. A rotating disk 403 is disposed at the bottom end of the lifting screw 402. Two limiting rods 404 are symmetrically disposed on both sides of the bottom end of the abutment support seat 401. The limiting rods 404 pass through the welding support platform 1. A side support frame 405 is disposed on the side of the welding support platform 1. An abutment screw 406 is threaded through the top end of the side support frame 405. A top abutment plate 407 is rotatably connected to the bottom end of the abutment screw 406.

[0029] The steel pipe limiting module 5 includes two steel pipe support seats 501 symmetrically arranged on both sides of the welding support platform 1. The top of each steel pipe support seat 501 is provided with a rotating groove 502. A reverse screw 503 is rotatably arranged in the rotating groove 502. One end of the reverse screw 503 rotatably passes through the inner wall of the rotating groove 502. A handle 504 is provided at the end of the reverse screw 503. Two drive screw sleeves 505 are symmetrically sleeved on the reverse screw 503. A clamping connecting plate 506 is provided at the top of each drive screw sleeve 505. A fixing clamp 507 is provided on the side of the clamping connecting plate 506.

[0030] Example 2: The difference between this example and Example 1 is that a limiting groove is provided on the bottom wall of the rotating groove 502, and a limiting block is provided at the bottom end of the driving screw sleeve 505. The limiting block is slidably inserted into the limiting groove.

[0031] This allows the drive screw sleeve 505 to slide within the limit groove of the limit block, preventing the drive screw sleeve 505 from rotating as the reverse screw 503 rotates.

[0032] Example 3: The difference between this example and Example 1 is that the threads on both sides of the reverse screw 503 are in opposite directions, and the drive sleeves 505 are threadedly connected to the reverse screw 503.

[0033] When the reverse screw 503 rotates, it can drive the two drive sleeves 505 fitted on it to move closer to each other.

[0034] Example 4: The difference between this example and Example 1 is that the inner wall of the fixing clamp 507 is an arc shape that fits against the welded steel pipe 7 of the space frame.

[0035] This allows the fixed clamping plate 507 to clamp and support the welded steel pipe 7 of the space frame under the push of the clamping connecting plate 506.

[0036] In this embodiment, the welding of existing metal grid structures requires manual alignment of the welding ball with multiple steel pipes before welding can be carried out. However, in actual manual operation, aligning the angle between the steel pipe and the welding ball is quite troublesome and prone to large deviations, making it difficult to accurately align and weld the subsequent connecting pipes, which is very inconvenient for workers to weld the grid structure.

[0037] In summary, during specific implementation, when the user needs to weld between the welded sphere 6 and the welded steel pipe 7 of the space frame, the user can use the movable wheels 3 at the bottom of the support leg 2 to push the device to the bottom side of the welded sphere 6. Then, by rotating the lifting screw 402, and because the limit rods 404 are provided on both sides of the contact support 401, the lifting screw 402 can push the contact support 401 to move upward, so that the bottom end of the welded sphere 6 is supported and fixed by the contact support 401. Then, by rotating the contact screw 406 threaded into the side support frame 405, the top contact plate 407 at the bottom end of the contact screw 406 can contact the upper end of the welded sphere 6, thereby stably fixing the welded sphere 6 on the welding support platform 1.

[0038] Next, the user can place the welded steel pipe 7 of the space frame on the steel pipe limiting module 5, so that the end of the welded steel pipe 7 can be close to the side of the welded sphere 6. The user can then rotate the handle 504, which will drive the reverse screw 503 to rotate. This will cause the drive screw sleeve 505 to drive the fixing clamp 507 to clamp and fix both sides of the welded steel pipe 7, so that the welded steel pipe 7 can remain fixed after being close to the side of the welded sphere 6. This makes the welding operation between the welded sphere 6 and the welded steel pipe 7 easier for the worker. Since the device is movable, it can be easily moved when the worker needs to perform the next welding, making it more flexible to use for connecting and welding metal space frames.
