Welding fixing jig

The utility model discloses a welding fixing jig. The welding fixing jig comprises a rack, the first fixing clamp is rotatably arranged on the rack, and the first fixing clamp is used for fixing a tubular workpiece; the second fixing clamp is arranged on the rack in a clamped mode, is opposite to the first fixing clamp, can move close to or away from the first fixing clamp and is used for fixing an end piece; when the second fixing clamp moves close to the first fixing clamp to enable the end piece to abut against the end of the tubular workpiece, the first fixing clamp drives the second fixing clamp to rotate relative to the rack. According to the technical scheme, the fixing accuracy and efficiency of the tubular workpiece and the end piece before welding are improved. 本实用新型公开一种焊接固定治具，其包括：机架；第一固定夹，所述第一固定夹可转动设于所述机架，所述第一固定夹用于固定管状工件；以及第二固定夹，所述第二固定夹设于所述机架，并与所述第一固定夹相对设置，所述第二固定夹可相对所述第一固定夹靠近或远离运动，所述第二固定夹用于固定端片；当所述第二固定夹靠近所述第一固定夹运动使所述端片抵接所述管状工件的端部时，所述第一固定夹带动所述第二固定夹相对所述机架转动。本实用新型技术方案旨在提高管状工件和端片在焊接前的固定准确性及效率。
