An adjusting assembly 300 for facilitating multi-directional angle adjustment of the welding head 5 is installed at the bottom of the L-shaped support rod 4;

[0029] The adjusting assembly 300 includes a connecting plate 301. On the front side of the lower end face of the connecting plate 301, a first support vertical plate 302 is fixedly installed. On one side of the first support vertical plate 302, a first protection box 303 is fixedly installed. A first driving motor 304 is fixedly installed inside the first protection box 303. The input end of the first driving motor 304 is connected to the power supply through an external cable. The output end of the first driving motor 304 passes through to one side of the first support vertical plate 302 through a bearing and is fixedly installed with a U-shaped bracket 305.

On one side of the second support vertical plate 307, a second protection box 308 is fixedly installed. A second driving motor 309 is fixedly installed inside the second protection box 308. The input end of the second driving motor 309 is connected to the power supply through an external cable. The output end of the second driving motor 309 passes through to one side of the second support vertical plate 307 through a bearing and is fixedly installed with an L-shaped first bracket 310. At the top of the L-shaped first bracket 310, an L-shaped second bracket 311 is fixedly installed. On one side of the welding head 5, a second connecting column 312 is fixedly installed. The second connecting column 312 and the two first connecting columns 306 are arranged in a T shape. The second connecting column 312 is rotatably connected to one side of the bottom of the L-shaped second bracket 311. The L-shaped first bracket 310 and the L-shaped second bracket 311 are arranged at a right angle;

[0030] The welding head 5 can be effectively adjusted in multiple directions through the provided adjusting component 300. When multi-directional angle adjustment of the welding head 5 is required, the driving motor 1 304 is started to drive the U-shaped bracket 305 to rotate, and the U-shaped bracket 305 drives the welding head 5 to rotate left and right. By starting the driving motor 2 309 to drive the L-shaped bracket 1 310 and the L-shaped bracket 2 311 to rotate, the welding head 5 is driven to rotate forward and backward, thereby realizing multi-directional angle adjustment of the welding head 5.

[0031] Embodiment 2

[0032] As Figures 1 to 6 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that the driving component 200 includes a driving motor 1 201 fixedly installed on one side of the bottom plate 1.

The top of the L-shaped support rod 4 is hollow, and the bottom wall of the top of the L-shaped support rod 4 is open. A driving motor 2 204 is fixedly installed on one side inside the top of the L-shaped support rod 4. The input end of the driving motor 2 204 is connected to a power source through an external cable. The output end of the driving motor 2 204 is fixedly installed with a threaded rod 2 205. The end of the threaded rod 2 205 away from the driving motor 2 204 is rotatably connected to the inner side wall of the L-shaped support rod 4. A sliding block 206 is threadedly connected to the outer surface of the threaded rod 2 205. The sliding block 206 matches the inner wall of the top of the L-shaped support rod 4, and the bottom of the L-shaped support rod 4 matches the limiting groove 202. The bottom of the sliding block 206 is fixedly installed on the upper end surface of the connecting plate 301. Through the provided driving component 200, the welding head 5 can be adjusted for movement in multiple directions. When multi-directional movement adjustment of the welding head 5 is required, by starting the driving motor 1 201 to drive the threaded rod 1 203 to rotate, the threaded rod 1 203 thread-pushes the welding head 5 at the bottom of the L-shaped support rod 4 to perform lateral movement adjustment during rotation. By starting the driving motor 2 204 to drive the threaded rod 2 205 to rotate, the threaded rod 2 205 thread-pushes the sliding block 206 to reciprocate during rotation, thereby driving the welding head 5 at the bottom of the sliding block 206 to perform longitudinal movement adjustment.

[0033] The lifting assembly 100 includes a driving motor three 101 fixedly installed on one side of the fixed vertical plate 2. The input end of the driving motor three 101 is connected to the power supply through an external cable. The output end of the driving motor three 101 passes through to one side of the fixed vertical plate 2 through a bearing and is fixedly installed with a bidirectional screw 102. One end of the bidirectional screw 102 away from the driving motor three 101 is rotatably connected to one side of the fixed vertical plate 2. The outer surfaces of both ends of the bidirectional screw 102 are threadedly connected with moving blocks 103. One side of the tops of the two moving blocks 103 is rotatably connected to a transmission rod 104. The tops of the two transmission rods 104 are rotatably connected to a support seat 105. The two support seats 105 are fixedly installed on the lower end surface of the placement plate 3. T-shaped sliding grooves 106 are symmetrically formed on the two fixed vertical plates 2.

The bottom of the moving block 103 is in contact with the upper end surface of the bottom plate 1. Through the arranged lifting assembly 100, the welding components on the placement plate 3 can be effectively driven to move upward to be in contact with the welding head 5 for welding. When it is necessary to drive the welding components on the placement plate 3 to move upward to be in contact with the welding head 5 for welding, the driving motor three 101 is started to drive the bidirectional screw 102 to rotate. The bidirectional screw 102 drives the two moving blocks 103 to move relatively. Then, through the mutual cooperation of the transmission rod 104 and the support seat 105, the welding components on the placement plate 3 are driven to move upward. When the welding components are in contact with the welding head 5, the welding head 5 is started for welding.

[0034] During operation, first, the welding components are fixedly clamped on the placement plate 3. Then, the driving motor three 101 is started to drive the bidirectional screw 102 to rotate. The bidirectional screw 102 drives the two moving blocks 103 to move relatively. Then, through the mutual cooperation of the transmission rod 104 and the support seat 105, the welding components on the placement plate 3 are driven to move upward, so as to drive the welding components to be in contact with the welding head 5. Then, welding is performed through the welding head 5. During the welding process, the driving motor one 201 is started to drive the threaded rod one 203 to rotate. During the rotation of the threaded rod one 203, the welding head 5 at the bottom of the L-shaped support rod 4 is pushed horizontally for adjustment by the thread. The driving motor two 204 is started to drive the threaded rod two 205 to rotate. During the rotation of the threaded rod two 205, the sliding block 206 is pushed to move reciprocally by the thread, so as to drive the welding head 5 at the bottom of the sliding block 206 to move vertically for adjustment, greatly improving the welding efficiency and the degree of intelligent automation.
