[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Example 1, as Figure 1As shown in the figure, a welding device for the production cabinet of a DC control cabinet includes a base 1. A welding robot arm 4 is fixedly installed at the upper end of the base 1. A control terminal 5 is fixedly installed at the upper end of the base 1. A rotating structure 2 is fixedly installed at the upper end of the base 1. A support and positioning structure 3 is slidably connected to the inner surface of the rotating structure 2. The rotating structure 2, the support and positioning structure 3, and the welding robot arm 4 are all connected to the control terminal 5 through cables.

[0035] It should be specifically noted that the above-mentioned welding robot arm 4 is a conventional robot arm in the prior art. A welding torch is installed at its head, and its movement path and the start and stop of the welding torch are controlled by the control terminal 5. This is a conventional technical means in the existing automatic welding technology. This structure has been widely used in the prior art. In the present invention, only its function of welding the steel frame in the DC control cabinet is utilized, and its internal structure, operating principle, wiring, and control method will not be elaborated.

[0036] During the operation of this embodiment, first, the support and positioning structure 3 is used to position and fix the main beam and cross beam of the steel frame. Through the cooperation of the rotating structure 2 and the support and positioning structure 3, it moves along a predetermined trajectory and moves to a predetermined position, facilitating the welding robot arm 4 to weld it. The positioning of the main beam and cross beam by the support and positioning structure 3 can avoid offset caused by the impact of the welding torch during the welding process, ensure the welding accuracy, and improve the quality and strength of the finished product.

[0037] Embodiment 2: On the basis of Embodiment 1, this embodiment realizes the function of driving the support and positioning structure 3 to rotate through the cooperation of the motor 1 23, the transmission shaft 24, and the translation drive assembly 25, thereby achieving the effect of facilitating the welding robot arm 4 to weld the steel frame from different angles, improving the welding efficiency and quality; through the cooperation of the motor 2 252, the gear 253, the rack 33, the limit wheel 254, and the limit groove 32, it realizes the function of driving the support and positioning structure 3 to move, thereby achieving the effect of cooperating with the welding robot arm 4 to weld from different positions, reducing omissions, and improving the strength of the welded finished product; through the cooperation of the main beam fixing component 34 and the chute 2 35, it realizes the function of fixing the main beam, thereby achieving the effect of reducing the displacement of the main beam caused by vibration during welding and movement and improving the welding accuracy; through the cooperation of the cross beam positioning component 37 and the chute 3 36, it realizes the function of fixing the cross beams of steel frames with different sizes and specifications, thereby achieving the effect of improving the applicable range.

[0038] Specifically, in order to drive the steel frame parts to be in different angles and positions following the drive of the motor 1 23, facilitating the welding robot arm 4 to weld them, refer to Figure 2, the rotating structure 2 includes a mounting base 21 fixedly connected to the upper end of the base 1. Symmetrically fixed to the front and rear of the upper end of the mounting base 21 are support arms 22. The inner surface of the mounting base 21 is rotatably connected to a transmission shaft 24. Fixedly connected to the right end of the mounting base 21 is a first motor 23. The output end of the first motor 23 is in transmission connection with the transmission shaft 24 through a coupling. Symmetrically rotatably connected to the upper part of the adjacent ends of the two mounting bases 21 are translation drive assemblies 25 slidably connected to the support and positioning structure 3. On both the left and right sides of the outer surface of the transmission shaft 24, transmission belts are used to transmit power to the adjacent translation drive assemblies 25.

[0039] The first motor 23 drives the transmission shaft 24 to rotate through a coupling. The two sides of the transmission shaft 24 drive the translation drive assemblies 25 to rotate through belts. Thus, the cooperation between the translation drive assemblies 25 and the support and positioning structure 3 drives the support and positioning structure 3 to rotate. The distance between the translation drive assemblies 25 and the mounting base 21 is greater than the width of the support and positioning structure 3 to avoid collisions during rotation.

[0040] During the process of the support and positioning structure 3 rotating following the translation drive assemblies 25, the steel frame fixed to its upper part will rotate accordingly. Its splicing seams, that is, the positions of the welding points, will be at different angles and positions under the action of rotation, facilitating the welding manipulator 4 to weld it at different angles, thereby improving the welding efficiency and quality.

[0041] Furthermore, to drive the support and positioning structure 3 to move and rotate, refer to Figure 3 , the translation drive assembly 25 includes a rotating base 251 rotatably connected to the adjacent mounting base 21. Symmetrically fixed to the front, rear, left, and right of the inner surface of the rotating base 251 are limiting wheels 254. The outer surfaces of the two limiting wheels 254 and the inner surface of the rotating base 251 are all slidably connected to the support and positioning structure 3. Rotatably connected to the inner surface of the rotating base 251 is a gear 253 meshing with the support and positioning structure 3. Fixedly installed on the inner surface of the rotating base 251 is a second motor 252 in transmission connection with the gear 253.

[0042] Furthermore, to cooperate with the action of the translation drive assembly 25 to drive the steel frame to move and rotate, refer to Figure 3 and Figure 4 , the support and positioning structure 3 includes a support platform 31 slidably connected to the inner surfaces of the two rotating bases 251. Fixedly connected to both the left and right ends of the support platform 31 are racks 33 meshing with the adjacent gears 253. Symmetrically opened at the front and rear of the upper end of the support platform 31 are limiting grooves 32 slidably connected to the outer surfaces of the adjacent limiting wheels 254. Symmetrically opened at the left and right of the upper end of the support platform 31 are a second sliding groove 35 and a third sliding groove 36. On the inner surfaces of the two second sliding grooves 35 are arranged main beam fixing components 34. On the inner surfaces of the two third sliding grooves 36 are jointly arranged a number of cross beam positioning components 37.

[0043] While the rotating base 251 drives the support platform 31 to rotate, the motor two 252 drives the gear 253 to rotate. By using the cooperation of the gear 253 and the rack 33, the support platform 31 is driven to slide linearly under the limitation of the limit groove 32 and the limit wheel 254, so as to make the support platform 31 in different horizontal or vertical positions, and cooperate with the action of the welding robot arm 4 to weld from different positions, reducing omissions and improving the strength of the welded product;

[0044] The main beam is fixed by the main beam fixing components 34 arranged on both sides. By using the cooperation of the main beam fixing components 34 and the chute two 35, the main beam is clamped and fixed at different positions, reducing the displacement caused by vibration during welding and moving, and reducing the influence of position deviation on welding accuracy.

[0045] Furthermore, the cross beam positioning component 37 is used to fix the cross beam of the steel frame, and through the cooperation of the cross beam positioning component 37 and the chute three 36, it can be fixed at different coordinates in the front and back positions of the support platform 31, so as to realize the welding requirements for steel frames of different sizes and specifications and improve the scope of application.

[0046] Embodiment 3: On the basis of Embodiment 2, this embodiment further realizes the rotation and positioning function of the support and positioning structure 3 through the cooperation of the motor one 23, the transmission shaft 24 and the translation drive component 25, which is convenient for the welding robot arm 4 to weld the steel frame at multiple angles, improving the welding efficiency and quality; through the cooperation of the motor two 252, the gear 253 and the rack 33, and the cooperation of the limit wheel 254 and the limit groove 32, the movement and positioning function of the support and positioning structure 3 is realized, and it cooperates with the welding robot arm 4 to weld at multiple positions, reducing omissions and enhancing the strength of the welded product; through the cooperation of the main beam fixing component 34 and the chute two 35, the fixing and positioning function of the main beam is realized, reducing the displacement of the main beam caused by vibration during welding and moving, and improving the welding accuracy; through the cooperation of the cross beam positioning component 37 and the chute three 36, the fixing and positioning function of the cross beams of steel frames of different specifications is realized, improving the scope of application of the equipment.

[0047] Specifically, to realize the positioning and fixing of the main beam of the steel frame, refer to Figure 5 , the main beam fixing component 34 includes a bidirectional screw 342 rotatably connected to the inner surface of the chute two 35. A motor three 341 drivingly connected to the bidirectional screw 342 is fixedly connected to the lower end of the support platform 31. Four clamping components 343 are slidably connected to the inner surface of the chute two 35 in an array distribution. The two clamping components 343 located on the front and back sides are threadedly connected to the outer surface of the bidirectional screw 342.

[0048] The motor three 341 drives the bidirectional screw 342 to rotate. During the rotation process, the bidirectional screw 342 further drives the clamping component 343 to slide in the second chute 35 through the cooperation with the clamping component 343, enabling it to move in two directions, forward and backward, from the middle, and then move to different positions on the main beam. By clamping and fixing multiple points on the main beam, the stability of the main beam during the welding process is ensured, and the position deviation is reduced.

[0049] Further, to fix the main beam of the steel frame, refer to Figure 6 and Figure 7 , the clamping component 343 includes a sliding seat 3431 that is slidably connected to the inner surface of the second chute 35 and the upper end of the support table 31. The upper end of the sliding seat 3431 is symmetrically provided with two first chutes 3432 on the left and right. The inner surfaces of the two first chutes 3432 are rotatably connected with threaded rods 3433. The inner surfaces of the two first chutes 3432 are slidably connected with clamping arms 3435 that are threadedly connected to the adjacent threaded rods 3433. The upper end of the sliding seat 3431 is fixedly connected with a double-shaft motor 3434 that is drivingly connected to the threaded rods 3433 on both sides. The inner surfaces of the two clamping arms 3435 are slidably connected with a number of limiting plates 3436 distributed linearly. One side of the number of limiting plates 3436 away from the double-shaft motor 3434 is fixedly connected with a limiting spring 3437 that is fixedly connected to the inner surface of the clamping arm 3435; the inner surface of the clamping component 343 that is threadedly connected to the outer surface of the bidirectional screw 342 is symmetrically slidably connected with a connecting rod 344 that is fixedly connected to the same-side sliding seat 3431.

[0050] The main beam is placed between the two clamping arms 3435 on the sliding seat 3431. The double-shaft motor 3434 drives the threaded rods 3433 to rotate. By the threaded action of the threaded rods 3433, the two clamping arms 3435 on both sides are driven to move closer inward. During the approaching process, the limiting plate 3436 first contacts the main beam and retracts into the clamping arm 3435 after being stressed. At this time, the limiting plate 3436 located on the upper side of the main beam will block the up and down movement of the main beam, thereby limiting it and reducing the deviation.

[0051] Embodiment 4. Based on Embodiment 3, this embodiment realizes the positioning function of the cross beam through the cooperation of the sliding table 371, the locking component 375, and the buckle groove 373, thereby achieving the effect of adapting to welding requirements at different positions; through the cooperation of the cross beam with the L-shaped clamping plate 372 and the spring rod 374, the fixing function of the cross beam is realized, thereby achieving the effect of stably fixing the cross beam and reducing wear; through the cooperation of the pull rod 376, the pull rope 3757, the elastic piston block 3756, the oil passage 3755, the piston rod, the wedge block 3754, the trapezoidal block 3753, and the arc-shaped block 3752, the unlocking and locking functions of the locking component 375 are realized, thereby achieving the effect of controlling the sliding and fixing position of the sliding table 371.

[0052] Specifically, to position and fix the cross beam of the steel frame, refer toFigure 8 and Figure 9 The crossbeam positioning assembly 37 includes a sliding table 371 slidably connected to the upper end of the support table 31. At the corresponding positions of the lower end of the sliding table 371 where the third chute 36 is located, locking components 375 are provided which are slidably connected to the inner surface of the adjacent third chute 36. Four L-shaped clamping plates 372 are slidably connected to the upper end of the sliding table 371 in a rectangular distribution. At the mutually approaching ends of the two L-shaped clamping plates 372 on the same side, a spring rod 374 is fixedly connected. A number of linearly distributed clamping grooves 373 are symmetrically distributed on the inner surfaces of the two third chutes 36 on both sides.

[0053] The sliding table 371 slides in the third chute 36 through the locking component 375. The position of the sliding table 371 can be restricted by the cooperation of the locking component 375 and the clamping grooves 373 opened in the third chute 36, so as to position the crossbeam at multiple different positions and meet the welding requirements at different positions.

[0054] Further, to position the crossbeam of the steel frame, refer to Figure 11 The locking component 375 includes a T-shaped block 3751 fixedly connected to the lower end of the sliding table 371. Four arc-shaped blocks 3752 are fixedly connected to the inner surface of the T-shaped block 3751 in a rectangular distribution. All four arc-shaped blocks 3752 penetrate through the inner surface of the T-shaped block 3751 and extend to the outer surface of the T-shaped block 3751. The two arc-shaped blocks 3752 on the same side are connected by a spring telescopic rod. At the mutually approaching ends of the two arc-shaped blocks 3752 on the same side, trapezoidal blocks 3753 are slidably connected, and the trapezoidal blocks 3753 are slidably connected to the inner surface of the T-shaped block 3751 through spring limiting rods. At the mutually approaching ends of the two trapezoidal blocks 3753 on both sides, wedge-shaped blocks 3754 are slidably connected. The wedge-shaped blocks 3754 are fixedly connected to the bottom wall of the inner surface of the T-shaped block 3751 through spring limiting rods.

[0055] Refer to Figure 11 An oil passage 3755 is opened on the inner surface of the sliding table 371. A piston rod slidably connected to the inner surface of the oil passage 3755 is fixedly connected to the upper end of the wedge-shaped block 3754. Elastic piston blocks 3756 are symmetrically arranged on the left and right sides of the inner surface of the wedge-shaped block 3754. A pull rope 3757 is fixedly connected to the mutually approaching ends of the two elastic piston blocks 3756 on both sides. The end of the pull rope 3757 far from the two elastic piston blocks 3756 on both sides is fixedly connected to a pull rod 376 slidably connected to the upper end of the sliding table 371.

[0056] The crossbeam presses downward along the L-shaped clamping plate 372 and squeezes open the spring rod 374 to enter between the L-shaped clamping plates 372. At this time, under the action of the spring rod 374, the L-shaped clamping plates 372 will closely adhere to and clamp both sides of the crossbeam. Rubber pads are attached to the vertical parts of the L-shaped clamping plates 372 to reduce the direct wear on the crossbeam and improve the friction force at the same time, ensuring stable fixation.

[0057] In the initial state, the arc-shaped block 3752 is located outside the T-shaped block 3751 and will be buckled in the buckling groove 373 in the corresponding third sliding groove 36, thereby locking the relative position of the sliding table 371 and preventing the sliding table 371 from shifting in position;

[0058] By pulling the pull rope 3757 through the pull rod 376, the elastic piston block 3756 is driven to move in the oil passage 3755. At this time, the spring in the elastic piston block 3756 is compressed, providing conditions for resetting. When the elastic piston block 3756 moves, the hydraulic oil in the oil passage 3755 will drive the wedge-shaped block 3754 to move through the piston rod due to pressure changes, and then the wedge-shaped block 3754 is used to push the trapezoidal block 3753 to move toward the front and rear sides. At this time, under the action of the spring limiting rod, the arc-shaped blocks 3752 will approach each other until they are completely received in the T-shaped block 3751. At this time, the sliding table 371 can slide on the support table 31 through the locking member 375;

[0059] After the pull rod 376 is released, it resets under the action of the spring in the elastic piston block 3756. The hydraulic oil in the oil passage 3755 is pressed by the elastic piston block 3756 toward the wedge-shaped block 3754 direction, and the wedge-shaped block 3754 resets. At this time, the trapezoidal block 3753 resets under the action of the spring limiting rod, and the arc-shaped block 3752 is pushed out by the trapezoidal block 3753 and enters the adjacent buckling groove 373 to lock the position of the sliding table 371.
