Technical Field

The invention relates to the technical field of airplane assembly, in particular to a linear drilling jig.

Background

Aircraft assembly involves the installation of a large number of standard components such as rivets, bolts, etc. in a linear arrangement, which involves a large number of drilling operations. When drilling these holes, the hole line is usually drawn by a steel ruler and a pencil, and then the holes are drilled one at a time, so that the efficiency is low. Some of the linearly arranged holes are linearly and uniformly distributed, and some of the linearly arranged holes are linearly and non-uniformly distributed. Some tools in the prior art are only suitable for the line drawing of linearly and uniformly distributed arrangement hole sites, and have complex structures. The prior art can meet the requirement that tools for leading holes and drawing lines in a straight line and non-uniform distribution are all special drilling dies or drawing templates with fixed structures, and the universality is poor.

Disclosure of Invention

In order to solve the technical problem, the invention provides a linear drill jig which is simple in structure and convenient to use.

The utility model provides a rectilinear drill jig, including the round bar, the guide rail, scale mark and drill jig body subassembly, drill jig body subassembly is including the drill jig body, locking screw, bush and indicating line, the guide rail is the thin straight square pole that there is the spout on one side, the guide rail upper surface marks the scale mark, drill jig body one end card in the drill jig body subassembly is in the spout of guide rail the other end through the round bar series connection together, the one end extension line of the indicating line on the drill jig body subassembly aligns with bush hole centre of a circle, the other end is facing to the scale mark of guide rail upper surface, be used for instructing the position of drill jig body subassembly on the guide rail.

Further, the jig body in the jig body assembly of the linear jig is fixed on the guide rail by welding or other methods, and the indication line on the jig body assembly is aligned with the zero graduation line of the graduation line on the guide rail.

Further, the number of jig body assemblies of the straight line type jig is 6 to 12.

Through the technical means, the linear drill jig has the beneficial technical effects of simple structure and flexible use. Through selecting the drill jig body subassembly of suitable quantity to adjust the drill jig body subassembly interval wantonly, can satisfy the lead hole needs of the part of different intervals, different hole numbers. The straight-line type drill jig is used for guiding the drill, so that the straightness, the hole spacing and the hole verticality of hole position arrangement can be better ensured, and the drilling quality is improved. The linear drill jig is used for guiding the drill, the parts with the same hole position arrangement can be used for multiple times by adjusting once during drilling, a large amount of line drawing work is saved, and the production efficiency is improved.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

The utility model provides a rectilinear drill jig, includes round bar 1, guide rail 2, scale mark 3 and a plurality of drill jig body subassembly 4, and drill jig body subassembly 4 includes drill jig body 41, locking screw 42, bush 43 and indicating line 44, and guide rail 2 is the thin square pole that one side has the spout, guide rail 2 upper surface mark has scale mark 3, and the 41 one end card of drill jig body in the drill jig body subassembly 4 of a plurality of is in guide rail 2's spout, and one end is in the same place through round bar 1 series connection, and the one end extension line of the last indicator line 44 of drill jig body subassembly 4 aligns with bush 43 hole centre of a circle, and the other end is facing to the scale mark 3 of guide rail 2 upper surface for instruct the position of drill jig body subassembly 4 on guide rail 2.

The drill jig body 41 in the drill jig body assembly 4 of the linear drill jig is fixed on the guide rail 2 by welding or other methods, the indication line 44 on the drill jig body assembly 4 is aligned with the zero marking line of the scale mark 3 on the guide rail 2, and other drill jig body assemblies 4 can slide along the round rod 1 and the guide rail 2 and can be fixed by the locking screw 42 after sliding to any position.

In order to meet the use requirements. The number of the jig body assemblies 4 of the straight line type jig is 6 to 12.

The use method of the linear drill jig comprises the following steps: and selecting a corresponding number of drill jig body assemblies 4 according to the requirement, adjusting the distance between the drill jig body assemblies 4 according to the requirement, and fixing by using the locking screw 42. After a hole is formed in the correct position on the airplane structure, the linear drilling jig is placed according to the requirement and is fixed on the formed hole through a process screw and a process nut. And drilling a hole on the airplane structure again according to the linear drilling jig, and fixing by using a process screw and a process nut, so that the linear drilling jig can be fixed on the airplane structure. And (4) sequentially using the inner holes of the bushings 43 on the rest drill jig body assemblies 4 on the linear drill jig to guide and drill the rest holes, thereby completing the hole drilling work.

The technical solutions described above only represent the preferred technical solutions of the present invention, and some possible modifications to some parts of the technical solutions by those skilled in the art all represent the principles of the present invention, and fall within the protection scope of the present invention.
