Abstract

The invention relates to a line returning device and method for plates. The line returning device comprises a first clamping plate and a second clamping plate. The first clamping plate comprises a first clamping portion and a first connection portion connected with one end of the first clamping portion. The second clamping plate comprises a second clamping portion and a second connection portion connected with one end of the second clamping portion. The opposite faces of the first clamping portion and the second clamping portion form a first clamping face and a second clamping face respectively. The first clamping portion and first scribing reference face intersection line forms a forward reference line, and the second clamping portion and second scribing reference face intersection line forms a reverse reference line. The forward reference line and the reverse reference line are parallel straight line sections and are parallel. The line returning method comprises clamping the plates to be scribed from the two sides of the whole plates by the first clamping portion and the second clamping portion, aligning the forward reference line with the main line, scribing a reverse to-be-scribed line along the reverse reference line, and scribing the reverse to-be-scribed line into the whole plate reverse line through a steel wire drawing method or a plate strip method easily to complete scribing. By means of the device and the method, high-accuracy forward and reverse scribing is achieved.

Description

technical field [0001] The invention relates to an assembly technology, in particular to a wire return device and a wire return method for board parts that need to be assembled and welded. Background technique [0002] The offshore engineering industry is an industry with high quality requirements, especially for some fatigue nodes and special areas, the assembly accuracy before welding is very high; in order to ensure the installation alignment accuracy of the structure, it is separated by the deck, bottom plate, and outer plate The cross structure requires positive and negative markings (theoretical lines and inspection lines) on the deck, bottom plate, and outer plate, and the deviation of the positive and negative lines is required to be less than 1mm. [0003] In the existing steel plate scribing technology, the scribing tools usually used by operators include scribing needles, scribing devices, etc. These scribing tools can realize the single-side setting-off work of t...
