Problems solved by technology

[0003] Large crankshafts are not uncommon in special fields such as industrial mining and energy. After the working surface of large crankshafts is worn out, submerged arc welding is required. The centers of rotation of the two do not coincide, thus causing great difficulties for submerged arc welding

Abstract

The invention relates to a rapid fixing frame for crankshaft submerged arc welding. The rapid fixing frame comprises a welding table, the left side and the right side of the welding table are each provided with a lathe, the right portion of the left lathe is correspondingly provided with a left rail chuck, the left portion of the right lathe is correspondingly provided with a right single-rail chuck, a round groove is formed in the middle of the right end face of the left rail chuck, a first laser lamp is fixedly mounted in the round groove, a light column of the first laser lamp coincides with the axis of the left rail chuck, a left middle groove is formed in the upper portion of the left end face of the left rail chuck, and the upper portion of the left middle groove extends to the circumference face of the left rail chuck; and the function that the left rail chuck and the right single-rail chuck carry out radial adjustment along the corresponding chucks is utilized for carrying out eccentric clamping on a crankshaft, a rotating shaft of the crankshaft is located on the side portions of the left rail chuck and the right single-rail chuck, and therefore the axis of a to-be-welded work shaft of the crankshaft is moved to the position where the axis of the left rail chuck and the axis of the right single-rail chuck coincide, and therefore the aim that the crankshaft rotates around the axis of the working shaft of the crankshaft is achieved.

Description

technical field [0001] The invention relates to the technical field of heat treatment fixing equipment for shaft parts, in particular to a fast fixing frame for crankshaft submerged arc welding. Background technique [0002] With the expansion of the field of people's activities, various large-scale equipment is widely used. Large-scale equipment wears a lot and is difficult to repair by traditional repair techniques. Submerged arc welding is widely used as an effective technical means for large-scale wear repair. [0003] Large crankshafts are not uncommon in special fields such as industrial mining and energy. After the working surface of large crankshafts is worn out, submerged arc welding is required. The rotation centers of the two do not coincide, so it causes great difficulties for submerged arc welding. Contents of the invention [0004] In view of the above defects, the present invention proposes a fast fixing frame for crankshaft submerged arc welding. [0005]...
