Description

[0001] This application is a divisional application of the application filed on October 17, 2025, with application number 2025114879402 and invention title "A Laser Welding Device for Weighing Instrument Production and Processing". Technical Field

[0002] This invention relates to the field of welding fixture technology, and in particular to a laser welding device for the production and processing of weighing instruments. Background Technology

[0003] In the field of weighing instrument manufacturing and processing, welding is a key process in constructing the structure of weighing instruments. Among them, welding of two sets of vertical pipes is more common. As an advanced welding technology with high precision and high efficiency, laser welding has become an ideal choice for welding vertical pipes due to its significant advantages such as concentrated energy density.

[0004] Traditional laser welding equipment, when fixing two sets of vertically welded pipes, has a structural design that results in the pipes being in a relatively fixed position after being fixed, lacking an effective rotation mechanism. In the actual welding process, the welding position often needs to be welded around the pipe to ensure the integrity and quality of the weld. However, because the existing tooling cannot flexibly rotate the workpiece with the actual welding position as the axis, the welder can only complete the welding work above the welding position first, then flip the workpiece as a whole, and continue to weld the remaining part of the weld, which leads to a decrease in welding efficiency.

Beneficial effects

[0016] 1. This invention, by incorporating an adjusting screw and an adjusting seat, enables the adjusting frame to move horizontally along the square tube to be welded via the clamping frame A and the clamping plate when the adjusting screw is rotated. This ensures that the welding position on the square tube, the end of the round tube to be welded, and the drive shaft are all on the same axis. The drive mechanism can then flexibly rotate the square tube around its actual welding position. Consequently, circumferential welding of the welding position can be completed without frequent workpiece flipping, significantly shortening welding time and improving welding efficiency. Simultaneously, it ensures the consistency and continuity of the welding position, effectively improving welding quality and reducing welding defects.

[0017] 2. The present invention, by setting an annular array of clamping rollers, can prevent the round tube to be welded from moving horizontally after being clamped; at the same time, it can make the round tube to be welded rotate axially; thus laying the foundation for the rotational welding of the square tube and the round tube to be welded.

[0018] 3. This invention, by incorporating a double-ended screw C and a guide rod, enables the two sets of clamping seats B to move in opposite directions when the double-ended screw C rotates, thereby allowing for the clamping of round tubes of different radii to be welded; the double-ended screw A and the movable seat allow for adjustment of the spacing between the two sets of clamping frames A according to the specific length of the square tube to be welded; the double-ended screw B and the clamping seat A allow the clamping plates to clamp and fix square tubes of different sizes to be welded using anti-slip pads; thus, it can fix the workpiece according to its actual specifications, enhancing the practicality of the fixing fixture.

[0019] 4. This invention, through the careful design of the reinforcing arm, reinforcing seat A, and reinforcing seat B, constructs a stable mechanical support structure, effectively enhancing the connection strength between the auxiliary frame and the drive shaft. This ensures excellent stability of the auxiliary frame during rotation, minimizing swaying and offset. Simultaneously, the precise cooperation between the reinforcing slide rail and the reinforcing column provides reliable guidance and support for the rotation of the adjustment frame driven by the auxiliary frame, making the entire rotation process smooth and stable. This ensures that the square tube to be welded remains stable during rotation, laying a solid foundation for high-quality welding operations. Attached Figure Description

Then, the double-ended screw B406 is rotated, and the double-ended screw B406 drives the two sets of clamping plates 408 to move in opposite directions through the clamping seat A407, so that the clamping plates 408 clamp and fix the square tube 5 to be welded through the anti-slip pad 409.
