Technical Field

[0001] The utility model relates to the technical field of welding robots, in particular to a multi-axis linkage welding robot. Background Technique

[0002] Welding is a necessary process method in modern mechanical manufacturing. With the progress of technology, the welding problems of coated steel plates and light metal materials pose new challenges to welding. The robot and automated laser welding technology in the welding process have greatly changed the face of welding technology;

[0003] At present, welding is very common in industrial production. When welding larger workpieces, it will be very difficult to use manual welding. Therefore, larger workpieces are usually welded by welding equipment. For example, the Chinese patent discloses an intelligent multi-axis industrial laser welding robot (authorization announcement number CN220480558U). This patented technology can fix the position of the metal plate and flip it while welding the metal plate through the design of driving the clamping mechanism to flip by a motor, reducing the time of manually flipping the metal plate and the position deviation generated during flipping while fixing the metal plate;

[0004] However, the above-mentioned disclosed welding robot still has some defects when in use: when the device is in use, most of the welding robots are fixed for welding and cannot be moved conveniently, resulting in the welding robot being unable to weld large welding workpieces, affecting the convenience and efficiency during welding. Therefore, the technical personnel in this field provide a multi-axis linkage welding robot to solve the problems raised in the above background technique. Content of the Utility Model

The top of the cross bar is slidably connected to a connecting table, and the upper part of the connecting table is connected and mounted to the bottom of the fixed frame. The elevating table and the connecting table are connected by a transmission mechanism.

[0010] As a further solution of the present utility model: The moving mechanism includes a driving motor mounted on the upper part of the adjustment table. An adjustment gear is mounted on the output shaft of the driving motor, and the adjustment gear is arranged on the lower side of the adjustment table. An adjustment rack engaged with the adjustment gear is mounted at the corresponding position on the upper part of the adjustment base.

[0011] As a further solution of the present utility model: Slide rails are symmetrically mounted on the upper part of the adjustment base. Slide sleeves that slide relative to each other are mounted at the corresponding positions on the bottom of the adjustment table.
