[0002] Roll welding, also known as seam welding, is a method of welding workpieces by using a pair of roller electrodes instead of the cylindrical electrodes used for spot welding.

[0027] A limiting nut is also provided on the part of the vertical limiting fixing bolt that is outside the vertical limiting space.

[0028] The advantages of this invention are as follows:

[0029] In this invention, the positive and negative roller electrodes are aligned on the same straight line, enabling them to make more stable contact with the same area on different surfaces of the workpiece. This minimizes the possibility of incomplete welding or omissions caused by the overlapping of the positive and negative roller electrodes, resulting in better welding performance. The roller adjustment mechanism allows for vertical adjustment of both the positive and negative roller electrode groups, making the invention adaptable to various workpiece types and ensuring stable contact between the roller electrodes and different workpieces, thus improving welding efficiency. Furthermore, the detachable connection between the first and second connecting parts allows the positive and negative roller electrode groups to be connected to the welding machine after adjustment, minimizing damage to the connecting parts and the welding machine during adjustment.

[0030] In this invention, the first adjustment unit, through the setting of the first adjustment cylinder, drives the positive roller electrode group to adjust vertically, while the setting of the first adjustment bearing and the first adjustment guide rod limits the movement path of the positive roller electrode group; the second adjustment unit, through the setting of the second adjustment hydraulic cylinder, drives the negative roller electrode group to adjust vertically, while the setting of the adjustment guide block and the adjustment guide space limits the movement path of the negative roller electrode group; thereby, the positive roller electrode of the positive roller electrode group and the negative roller electrode of the negative roller electrode can be adjusted more precisely, and make more stable and close contact with the workpiece, resulting in better welding effect of this invention.

[0031] In this invention, the cooperation between the first electrode rotating shaft and the first electrode rotating bearing, and the cooperation between the second electrode rotating shaft and the second electrode rotating bearing, enables the positive roller electrode connected to the first electrode rotating shaft and the negative roller electrode connected to the second electrode rotating shaft to roll synchronously in response to the workpiece's entry and exit movements, thereby achieving welding work on the workpiece during the rolling process; the first electrode seat, the second motor seat, the first electrode housing, and the second electrode housing make the assembly of the first electrode rotating shaft and the second electrode rotating shaft more stable.

[0032] In this invention, the first connecting part, the second connecting part, the first electrode support, the second electrode support, the first electrode seat, the second electrode seat, the first electrode rotation shaft, the second electrode rotation shaft, the positive roller electrode, and the negative roller electrode are made of copper; thereby, the positive roller electrode group and the negative roller electrode group are made of copper while being assembled, so as to achieve conductivity between the positive roller electrode and the negative roller electrode.

[0033] In this invention, the detachable connection between the left and right sides of the motor base plate and the base plate of the motor base facilitates the assembly and disassembly of the first and second electrode rotating shafts, making the installation and subsequent maintenance of this invention more convenient. It also allows the invention to replace the first and second electrode rotating shafts with different shapes and materials to match the processing requirements of different workpieces.

[0034] In this invention, a welding fixture is used to stably weld the workpiece. The welding fixture includes a workpiece limiting device and a height adjustment device. The workpiece is limited by the workpiece limiting device, so that the workpiece can move according to the limited path, thus avoiding welding errors as much as possible. The height adjustment device makes the workpiece fit more closely with the positive roller electrode and the negative roller electrode, making the contact between the workpiece and the positive roller electrode and the negative roller electrode more stable and the welding effect better.

[0035] In this invention, the height adjustment device includes a first adjustment component and a second adjustment component, which are respectively disposed on both sides of the positive roller electrode and the negative roller electrode; this allows the workpiece to be welded more stably and improves the welding effect.

[0036] In this invention, the first adjustment component and the second adjustment component achieve independent adjustment through the setting of the first adjustment hydraulic cylinder and the second adjustment hydraulic cylinder; thus, this invention can not only process flat workpieces, but also adjust the position of each welding part limiting device and the position of the negative roller electrode group by adjusting the first adjustment component, the second adjustment component and the second adjustment part, thereby enabling this invention to process workpieces of different shapes and types.

[0037] In this invention, a horizontal limiting component applies a horizontal limiting force to the workpiece; the first horizontal contact portion and the second horizontal contact portion are respectively rolledly connected to the first horizontal assembly rod and the second horizontal assembly rod, and the workpiece passes between the first horizontal contact portion and the second horizontal contact portion, so that while the first horizontal contact portion and the second horizontal contact portion contact the workpiece and restrict its movement path to improve the welding effect, they do not affect the movement of the workpiece; the contact groove further improves the cooperation between the workpiece and the first horizontal contact portion and the second horizontal contact portion, and enhances the limiting effect of the first horizontal contact portion and the second horizontal contact portion on the workpiece; through horizontal limiting... The coordination of the space, the horizontal limiting block, and the horizontal limiting fixing bolt allows the first and second horizontal movable blocks to move and bring the first and second horizontal contact parts into contact with the workpiece. By adjusting the horizontal limiting fixing bolt, the distance between the first and second horizontal contact parts is adjusted, resulting in a tighter fit between the first and second horizontal contact parts and the workpiece, and a better effect of the first and second horizontal contact parts in restricting the workpiece. At the same time, the distance between the first and second horizontal contact parts can be adjusted according to different types of workpieces, making this invention applicable to welding work of various types of workpieces.

[0038] In this invention, the auxiliary limiting component further applies a horizontal limiting force to the workpiece, making the workpiece more stable during welding. The auxiliary limiting component applies a limiting force to the workpiece through the auxiliary limiting cylinder, and the cylinder arm of the auxiliary limiting cylinder is detachably connected to the auxiliary limiting block. This allows the auxiliary limiting block to be replaced promptly after it is damaged upon contact with the workpiece.

[0039] In this invention, a vertical limiting force is applied to the workpiece by setting a vertical limiting component; the two ends of the second vertical contact portion are rotatably connected to the first vertical limiting plate and the second vertical limiting plate, respectively, and the two ends of the first vertical contact portion are rotatably connected to the first vertical assembly block and the second vertical assembly block, respectively. This allows the first and second vertical contact portions to contact the workpiece and restrict its movement path to improve the welding effect without affecting the movement of the workpiece. Through the cooperation of the vertical limiting space, the vertical limiting fixing bolt, and the vertical assembly block, the distance between the first and second vertical contact portions can be adjusted, making this invention applicable to different types of workpieces.

[0040] The opening and top cover allow the invention to disassemble or replace the first vertical contact part according to the needs of the workpiece.

[0041] After adjusting the distance between the first and second vertical contact parts, the vertical limiting fixing bolt can be reinforced by setting a limiting nut. Attached Figure Description
