Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please see Figures 1 to 5 This embodiment provides a multi-station welding worktable for a laser welding machine. The worktable 4 includes a rotary table 1, a fixed table 2, a clamping plate 3, a drive gear 4, and a drive rack 5. The rotary table 1 is used to fix the workpiece to be laser welded, the fixed table 2 is used to support and connect the rotary table 1, the clamping plate 3 is used to clamp the workpiece to be laser welded, and the drive gear 4 and drive rack 5 are used to drive the clamping plate 3 to rotate.

[0023] A rotary table 1 is mounted on a fixed table 2 and is configured to rotate directionally along a fixed axis. Generally, the rotary table 1 can be driven by an intermittent motion mechanism, such as a cam divider. The rotary table 1 has multiple mounting slots 1a, which are arranged circumferentially along the rotation axis of the rotary table 1. Each mounting slot 1a is provided with multiple clamping plates 3. The clamping plates 3 extend to both sides to form rotating parts 3a. The rotating parts 3a are rotatably connected to the rotary table 1, and the rotation axis is perpendicular to the rotation axis of the rotary table 1. The drive gear 4 is fixedly connected to the rotating parts 3a.

[0024] Along the rotation direction of the rotary table 1: The fixed table 2 is sequentially equipped with multiple welding stations, each corresponding to a laser head 12 for welding the workpiece. A flipping station is located between the welding stations, with a drive rack 5 fixed thereto. The drive rack 5 meshes with the drive gear 4 to rotate the clamping plate 3 by a predetermined angle. Preferably, the number of teeth on the drive rack 5 is half the number of teeth on the drive gear 4, so the drive rack 5 causes the drive gear 4 to rotate half a turn, flipping the workpiece on the clamping plate 3. Preferably, the fixed table 2 also has a loading station and a unloading station, used for loading and unloading workpieces respectively. Along the rotation direction of the rotary table 1: the loading station, multiple welding stations, and the unloading station are sequentially arranged. Preferably, there are two welding stations, and four mounting slots 1a and clamping plates 3, corresponding to two welding stations, one loading station, and one unloading station. In a further preferred embodiment, along the rotation direction of the rotary table 1, there is another flipping station between the last welding station and the unloading station. This flipping station is also equipped with a drive rack 5, which is used to flip the workpiece after both sides have been welded, so as to restore it to the front side.

[0025] Preferably, the multi-station welding table of the laser welding machine further includes a limiting plate 6 and positioning posts 7. The limiting plate 6 is arranged in a ring on the outside of the rotary table 1, and the limiting plate 6 is disconnected at the flipping station. The side of the rotating part 3a away from the rotary table 1 is connected to two positioning posts 7. The two positioning posts 7 abut against the upper side of the limiting plate 6 to restrict the rotation of the rotating part 3a. During the rotation of the rotary table 1, the two positioning posts 7 abut against the limiting plate 6, and the clamping plate 3 cannot rotate at this time. When it moves to the flipping station, the limiting plate 6 is disconnected here, the drive gear 4 meshes with the drive rack 5, and drives the clamping plate 3 to rotate, completing the workpiece flipping. More preferably, the multi-station welding table of the laser welding machine further includes positioning wheels 8. The two positioning posts 7 are rotatably connected to the two positioning wheels 8 respectively. The positioning wheels 8 abut against the limiting plate 6, converting sliding friction into rolling friction and reducing component wear.

[0026] Preferably, the multi-station welding table of the laser welding machine further includes positioning pins 9, and the clamping plate 3 has a clamping opening 3b. Multiple positioning pins 9 are fixedly connected to the inside of the clamping opening 3b. The positioning pins 9 are set in the same direction as the clamping opening 3b. The positioning pins 9 are used for workpiece positioning. Generally, a positioning port is opened on the station to cooperate with the positioning pins 9 to achieve workpiece positioning. More preferably, the multi-station welding table of the laser welding machine also includes a spring block 10 and a pressure spring 11. Multiple spring blocks 10 are set in the clamping opening 3b. The two ends of the pressure spring 11 are respectively connected to the spring block 10 and the clamping plate 3. The pressure spring 11 and the pressure block are used to press and clamp the workpiece.

[0027] In summary, the multi-station welding workbench of the laser welding machine provided by this utility model has the workpiece clamped and fixed by the clamping plate 3. When it moves to the welding station, the laser welding head performs welding work. A drive rack 5 is provided between the two welding stations, which can drive the drive gear 4 to rotate and flip the clamping plate 3, thereby realizing the flipping of the workpiece. The laser head 12 of the other welding station can then perform welding work on the reverse side of the workpiece, realizing process automation and greatly improving production efficiency.

[0028] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
