S6, beginning to drill and rivet: according to the scanning result determined in the step S5, the second linear module 4 drives the third linear module 5 and the mounting seat 6 to move integrally along the Y axis direction again, in this process, the first drilling device 11 on the mounting seat 6 sequentially drills holes on each workpiece to form a rivet hole, and after the drilling is finished, the second linear module 4 drives the mounting group to move along the Y axis direction, and sequentially penetrates rivets into the rivet holes through the riveting gun 12 and performs riveting. Of course, a rivet hole may be drilled and then subjected to a riveting operation, which may be specifically selected according to actual needs.
In this step, as shown in fig. 3, the first rivet hole and the last rivet hole of each workpiece are located at a distance G (generally 20mm by default) from the edge line of the workpiece in the Y-axis direction.
The number of actual rivet holes, i.e., the number of holes ═ Round ((L-2G)/X) + 1;
the actual rivet hole spacing, i.e. the hole spacing of (L-2G)/Round ((L-2G)/X),
the Round is a Round function, and X is an input reference coefficient, which can be modified according to the actual situation, so that when G is determined, for example, G is 120mm, the number of holes and the hole spacing can be controlled by only adjusting the value of X.
S7, after the flange drilling and riveting are finished, the glue gun 14 is driven to the joint (the area indicated by the part a in the figure 3) of the flange and the air pipe through the double-shaft linear module, and the glue gun 14 is driven to glue all the workpieces in sequence along the Y-axis direction.
The present embodiment is mainly used for operations such as drilling and riveting glue on a flange above a workpiece.
The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of the present invention.
