The invention discloses a magnetic line drawing device used for drawing a line before drilling a part. The device comprises a regulating block in a regulating mechanism, a magnet and a locating sliding block, wherein one end of the upper surface of the regulating block is provided with a concave hole in which the magnet is installed, the other end of the upper surface of the regulating block is provided with a long slot in which the locating sliding block is placed; the locating sliding block is in an L shape, and has a bottom wall and a side wall, wherein the bottom wall slides in the long slot, and the side wall is slightly higher than the upper surface of the regulating block; an alignment mechanism comprises a hollow steel ball and a hollow steel ball carrier, wherein the hollow steel ball is placed in the hollow steel ball carrier which is in a transparent box shape, transparent lubricating oil is filled in the hollow steel ball carrier, three marking lines are arranged in the middle of the outer surface of the transparent box body, spaces between the marking lines are equal and are equal to the maximum semi-diameter of the hollow steel ball. The device is simple and applicable in structure, low in manufacturing cost and accurate to locate, the drilling difficulty in the parts in either an incompletely opened area or an unopened area can be reduced greatly, the drilling precision can be improved, and the production efficiency and product quality can be improved.
Description
technical field [0001] The invention relates to the field of aeromechanical processing, in particular to a magnetic line drawing device and method, which are mainly used for drawing fastener position holes in closed areas during aircraft assembly. Background technique [0002] During the trial production process of a certain key model, the fastener holes of the skin and the stringers and frames need to ensure the margins on the stringers and frames. The space is relatively closed, and it is difficult to drill holes on the side of the stringer and the frame. Contents of the invention [0003] In order to overcome the difficulties in the prior art, the present invention provides a magnetic line drawing device. By setting an adjustment mechanism and an alignment mechanism, the device can freely adjust the hole margin of the fastener, and the center of the magnet is the center of the hole to be processed. , The hollow steel ball carrier is in the shape of a transparent box wi...
