Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to a welding mechanism of a suspended beam erecting machine and a use method thereof. Background Art

[0002] The suspended beam-erecting welding mechanism is a highly efficient equipment specially used for welding large or heavy workpieces. Its core lies in its ability to move and rotate in any direction to meet the welding needs of complex workpieces. It is generally suspended on a special frame and can perform longitudinal and lateral movement and rotation welding.

[0003] The existing suspended beam erector welding mechanism is composed of welding clamps, welding machine transformers, welding machine controllers, water cooling systems, pneumatic pressurization systems and suspension devices. First, the workpiece is placed between the electrodes of the welding clamps, and then the welding switch is pressed. The pressurization program segment starts, the electromagnetic air valve is activated, and compressed air enters the welding machine cylinder to activate the welding clamp electrodes and press the workpiece. After an appropriate delay, the welding program segment starts. At this time, the primary coil of the welding transformer is connected to the power supply through the control of the thyristor, and the secondary generates welding current to weld the workpiece. After the welding is completed, the welder enters the maintenance program. After the pressure is maintained for a period of time, the electromagnetic air valve is disconnected, the welding clamp releases the workpiece, and the welder enters the rest program to complete a welding cycle.

[0004] Although the existing suspended beam erector welding mechanism can complete the welding work of the workpiece, the welding rod or welding wire required for welding is still manually picked up and placed to complete the loading work of the welding gun. This is not only troublesome, time-consuming and labor-intensive, and reduces the welding efficiency of the welding gun, but also causes the welding work to be constantly paused, making it impossible to continuously weld the workpiece, and thus the welding strength of the workpiece cannot be ensured.

[0036] 2. When the welding wire and the welding rod need to be quickly guided, the motor A drives the rotating shaft A to rotate, the rotating shaft A drives the two rotating disks to rotate, the two rotating disks drive their respective mounting columns to rotate synchronously at the same time, and the multiple mounting columns drive their respective guides to rotate synchronously;

[0039] 5. When the welding gun needs to replace welding rods and welding wires of different specifications, the motor B drives the rotating shaft B to rotate, and the rotating shaft B drives the threads thereon to rotate synchronously. The two threads with opposite rotation directions drive the two sliders to slide toward and in opposite directions. The two sliders drive their respective sleeves to slide toward and in opposite directions. The two sleeves drive their respective fixed plates and the control parts thereon to move toward and in opposite directions. The control parts change the initial positions of the guide parts on the two adjacent mounting columns by moving toward and in opposite directions and cooperating with the springs. The guide parts on the two adjacent mounting columns change the size of the space for the two guide grooves to clamp the welding rod or welding wire.

When the guide unit rotates to a position matching the discharge end of the material preparation box, the control unit can change the size of the clamping space of the guide unit, so that the guide unit can clamp the welding rod or welding wire located at the discharge end of the material preparation box, and then the guide unit can drive the clamped welding rod or welding wire to move toward the direction close to the feeding end of the welding gun. When the guide unit rotates to a position matching the feeding end of the welding gun, the control unit adjusts the clamping space of the guide unit again, so that the guide unit releases the clamping of the welding rod or welding wire, and then the welding rod or welding wire can effectively and quickly enter the welding gun, thereby realizing automatic feeding of the welding rod or welding wire, ensuring the continuity and stability of the welding process of the welding gun, and enabling the welding mechanism to more flexibly adapt to different welding requirements and working environments, thereby improving the welding efficiency and welding quality of the welding mechanism;

[0042] The regulating component can drive the control units arranged on both sides of the guide unit to move in opposite directions by rotating, thereby changing the size of the clamping space of the guide unit, so that the welding gun mechanism can autonomously adjust the size of the clamping space of the guide unit according to the use specifications of the welding rod or welding wire, so that it can effectively and quickly guide the welding rod or welding wire of the required specifications into the welding gun, thereby ensuring the continuity and stability of the welding process of the welding gun and improving the welding efficiency of the welding mechanism.

[0078] like Figures 1 to 7 As shown, a method for using the above-mentioned suspended beam erecting machine welding mechanism is as follows:

[0079] 1. The main body 100 of the beam erecting machine can change the horizontal and vertical positions of the welding robot 200, thereby changing the horizontal position of the welding gun 700. The motor C in the base 210 drives the rotating arm A220 to rotate, the motor D in the rotating arm A220 drives the rotating arm B230 to rotate, the motor E in the rotating arm B230 drives the rotating arm C240 ​​to rotate, the motor F in the rotating arm C240 ​​drives the rotating arm support 250 to rotate, and the motor G in the rotating arm support 250 drives the triangular support 300 to rotate.

[0081] 3. When the two guide members 623 on the two adjacent mounting columns 624 rotate synchronously to the position matching with the discharge end of the material preparation box 500, the two guide members 623 also rotate synchronously to the position slidingly matching with the control member 633. The control member 633 can drive the two guide members 623 to approach each other by cooperating with the spring 625, thereby reducing the space between the two guide grooves 626, so that the two guide grooves 626 can clamp the welding rod or welding wire and drive it to move toward the direction close to the feeding end of the welding gun 700;

[0082] Fourth, when the two guide members 623 on the two adjacent mounting posts 624 rotate synchronously to the position matching with the feeding end of the welding gun 700, the two guide members 623 rotate synchronously to the position separated from the control member 633, so that the two guide members 623 are again slidably matched with the side wall of the fixed plate 631 on which the control member 633 is not provided, and the spring 625 can drive the two adjacent mounting posts 624 away from each other through its own elastic force, and the two mounting posts 624 simultaneously drive their respective guide members 623 away from each other, thereby expanding the space between the two guide grooves 626, so that the two guide grooves 626 away from each other can release the clamping of the welding rod or welding wire, so that the welding rod or welding wire can effectively and quickly enter the welding gun 700, realize the automatic feeding of the welding rod or welding wire, and ensure the continuity and stability of the welding process of the welding gun 700;

[0083] 5. When the welding gun 700 needs to replace welding rods or welding wires of different specifications, the motor B810 drives the rotating shaft B820 to rotate, and the rotating shaft B820 drives the thread 830 thereon to rotate synchronously, thereby driving the two sliders 840 to slide toward or in the opposite direction, and the two sliders 840 drive their respective sleeves 632 to slide toward or in the opposite direction, and the two sleeves 632 drive their respective fixed plates 631 and the control members 633 thereon to move toward or in the opposite direction. The control member 633 can change the initial position of the guide member 623 on the two adjacent mounting columns 624 by moving toward or in the opposite direction and cooperating with the spring 625, thereby changing the size of the space that the two guide grooves 626 can clamp the welding rod or welding wire, so that the welding gun 700 mechanism can autonomously adjust the size of the clamping space of the guide unit 620 according to the use specifications of the welding rod or welding wire, so that it can effectively and quickly guide the welding rod or welding wire of the required specifications into the welding gun 700, thereby ensuring the continuity and stability of the welding process of the welding gun 700.
