The utility model relates to a positioning and pressing device for laser welding equipment used for flat butt joints and corner joints of thin plates. The difference is that: one group of gantry is a fixed gantry; the other group of gantry is a mobile gantry with a longitudinal guide rail below it to move longitudinally; two groups of gantry are set opposite to each other; The number of pressing devices can be adjusted according to the implementation situation, generally 4-20; there is also a set of cylinder-driven angular joint longitudinal positioning devices on the beam of the fixed mast, the number can be adjusted according to the implementation situation , generally 2-8 pieces; electromagnets are installed on the angular joint longitudinal positioning device; a support platform is provided under the two sets of gantry frames; a vertical butt joint longitudinal positioning device that can be lifted and lowered is provided inside the support platform; the side of the support platform is provided with Horizontal positioning block; steel ball rollers are arranged in the upper plane of the support platform, the number can be adjusted according to the implementation situation, generally 30-300 pieces, and springs are arranged under each steel ball roller.

In the embodiment, 8 sets of pressing devices are evenly distributed on each beam, among which 3 sets of corner joint longitudinal positioning devices are installed on the beam corresponding to the fixed door frame, and 2 sets of vertical butt joint positioning devices that can be lifted and lowered are installed in the support platform. device. The utility model can realize the flat butt joint positioning and compaction of thin plates, and can also realize the positioning and compaction of thin plate corner joints. The thin plate is pressed by 8 sets of liftable pressing devices driven by oil cylinders, and the thin plate is supported by the support platform with spring steel ball rollers. A flat butt joint longitudinal positioning device and a transverse positioning block are installed on the supporting platform to realize the positioning of the thin plate butt joint. A corner joint longitudinal positioning device is installed on the fixed door frame, and an electromagnet is arranged on the corner joint longitudinal positioning device to realize the positioning of the thin plate corner joint.

Attached Figure 2 shows the working state of the flat butt joint of the thin plates. For the convenience of observation and explanation, two holes are dug at the junction of the two thin plates. The positioning device 8 is raised, and the thin plate A is moved to the bottom of the fixed door frame 1, and the position of the thin plate is adjusted so that the lateral and longitudinal edge faces of one side of the thin plate A are respectively against the horizontal positioning block 6 and connected with the longitudinal positioning device 8, and the upper side of the fixed door frame 1 is fixed. The pressing device 4 is lowered until the thin plate A is pressed, the flat docking longitudinal positioning device 8 is lowered, the thin plate B is moved to the bottom of the moving door frame 2, and the position of the thin plate is adjusted so that the horizontal and longitudinal edge ends of one side of the thin plate respectively lean against the horizontal positioning block 6 and one side of the longitudinal edge of the thin plate A, the pressing device 4 above the mobile door frame 2 is lowered until the thin plate B is pressed, and then the flat butt welding process can be carried out.
