Title:
WELDING MACHINE FOR CONCAVE PIECE
Document Type and Number:
WIPO Patent Application WO/2019/071639
Kind Code:
A1
Abstract:
Disclosed is a welding machine (100) for a concave piece, the welding machine comprising: a rotary table (5), a plurality of positioning fixtures (53), an assembly mechanism (11) and a welding module (6). The rotary table (5) comprises a driving base (51) and a multi-station circular rotary disk (52) arranged on the driving base (51). The multi-station circular rotary disk (52) is equally circumferentially divided into a plurality of stations; each of the stations is provided with one positioning fixture (53); and a plurality of L-shaped concave pieces (102) are arranged on a side surface of each of the positioning fixtures (53), a threaded stud (104) is arranged on a top surface of each of the positioning fixtures (53), one end of the concave piece (102) is sheathed on the threaded stud (104), and the assembly mechanism (11) is used for clamping the concave piece (102) and the threaded stud (104). A light beam emitted from the welding module (6) directly reaches the top surface of the positioning fixture (53) to weld the concave piece (102) and the threaded stud (104) together. The welding machine for a concave piece clamps the concave piece and the threaded stud by using the assembly mechanism, thereby realizing the precise positioning of the concave piece and the threaded stud, avoiding the offset of the concave piece from the threaded stud during welding, and improving the welding yield of the concave piece and the threaded stud.
