Description

Technical Field

[0001] This patent relates to the field of thin plate welding technology, specifically a thin plate welding fixture that facilitates welding. Background Technology

[0002] Welding technology is one of the key technologies in engineering manufacturing. The application fields of welded structures cover many fields such as machinery, shipbuilding, military industry, and petrochemicals. In the manufacturing of precision structures, thin plates need to be welded. During the welding process, thin plates need to be held in place by tooling fixtures. Due to their thinness, the welding force during the welding process can cause the weld point of the thin plate to sink, resulting in the problem of the thin plate tilting during welding. At the same time, there are problems with the welding fixtures for thin plates that are convenient for welding but are not fixed. After welding one side of the thin plate, it is necessary to disassemble the thin plate and change the direction for welding, which reduces the welding efficiency. Summary of the Invention

[0004] To achieve the above objectives, this patent provides the following technical solution: a thin plate welding fixture for easy welding, comprising a box body, a worktable mounted on the box body, a square opening on the worktable, an electric push rod mounted inside the box body, a top plate mounted on the output end of the electric push rod, the output end of the electric push rod extending outside the square opening, and a welding robot mounted on the worktable;

[0005] The workbench is equipped with two drive structures, which are symmetrically distributed on both sides of the center line of the workbench. Each drive structure includes a vertical plate, a circular groove, a bearing, a rotating shaft, a servo motor, a fixture, and a thin plate.

[0006] The upright plate is mounted on the workbench, the circular groove is formed on the upright plate, the outer ring of the bearing is installed in the circular groove, the rotating shaft is installed in the inner ring of the bearing, the servo motor is mounted on the upright plate, the outer side of the rotating shaft is connected to the output shaft of the servo motor, the clamp is installed on the inner side of the rotating shaft, the thin plate is clamped in the clamp, and the top plate rests on the thin plate.

[0007] Preferably, the clamp includes a clamping plate, a threaded hole, and a threaded rod;

[0008] The clamping plate is installed inside the rotating shaft, the thin plate is placed inside the clamping plate, the threaded hole is opened inside the clamping plate, the threaded rod is sleeved inside the threaded hole, and the threaded rod abuts against the thin plate.

[0009] Preferably, the welding robot is mounted on the workbench via a fixing structure. The number of fixing structures is four, and the fixing structures are distributed in a ring at equal intervals between the welding robot and the workbench. Each fixing structure includes mounting holes, bolts, and threaded grooves.

[0010] The mounting hole is formed on the base of the welding robot, the threaded groove is formed on the worktable, the bolt passes through the mounting hole, and the bolt is fitted into the threaded groove.

[0011] Preferably, the size of the top plate is smaller than the size of the square opening, and the lowest point of the output end of the electric push rod is lower than the lowest point of the square opening.

[0012] Preferably, a base is mounted on the upright plate, and the servo motor is installed inside the base, with the base and servo motor being configured correspondingly.

[0013] Preferably, a handle is installed on the threaded rod, and the handle is correspondingly arranged with respect to the threaded rod.

[0014] Compared with existing technologies, the beneficial effects of this patent are as follows: This convenient welding fixture for thin plates has the following advantages compared with traditional technologies:

[0015] The thin plate is clamped and fixed in the fixture, and the weld joint of the thin plate is in contact. Then the output end of the electric push rod drives the top plate to move upward and contact the thin plate, making the thin plate horizontal. At this time, the welding robot performs horizontal welding on the top of the thin plate. Meanwhile, the output shaft of the servo motor drives the rotating shaft to rotate 180 degrees through the bearing. After the top plate moves down, it continues to press against the thin plate, so that the other side of the thin plate can be welded. This facilitates welding both sides of the thin plate and improves welding efficiency. Attached Figure Description

A rotating shaft 404 is installed in the inner ring of the bearing 403. A servo motor 405 is mounted on the vertical plate 401. The servo motor 405 is powered on and operates synchronously and in the same direction. A base 11 is mounted on the vertical plate 401. The servo motor 405 is installed in the base 11. The base 11 and the servo motor 405 are correspondingly arranged. The outer side of the rotating shaft 404 is connected to the output shaft of the servo motor 405. A fixture 406 is mounted on the rotating shaft 404.
