technical field

The present application relates to the field of workpiece processing, in particular to an auxiliary device for scribing a workpiece.

Background technique

Scribing is an important process in mechanical processing and is widely used in single-piece or small-batch production. A single workpiece often needs to be assembled with other workpieces after production and processing, and the workpieces are fixed by welding. In order to ensure the accuracy of the assembled workpieces, it is necessary to draw positioning lines on the surface of the workpieces before welding and fixing.

At present, the existing scribing mainly relies on manual measurement and marking. The staff first uses measuring tools such as rulers, squares, and T-squares to measure and mark the scribing position on the surface of the workpiece, and then uses a stylus to mark the surface of the workpiece. draw the line.

For the above-mentioned related technologies, manual marking needs to be marked first and then marked. Accurate measurement marking takes a lot of time for the staff, and when the positioning line to be drawn is long, the staff uses a stylus to do it. Scribing is prone to low scribing accuracy, and the inventor believes that manual scribing is time-consuming and labor-intensive and has low accuracy.
