Abstract
A body of the marking device is of a flat plate structure, one side of the flat plate is a reference surface, a scale indicating block perpendicular to the reference surface of the flat plate is arranged on the reference surface of the flat plate, and the surface of the scale indicating block is provided with size scales far away from the reference surface.
Description
Technical Field
The utility model relates to a scribing device for hole sites on the edges of parts in an airplane assembly area, which is particularly suitable for quickly finding out hole sites and assisting in hole making.
Background
Hole making is one of the most common steps in aircraft assembly, and is also the most frequent operation in aircraft assembly. In order to ensure the quality of hole making, the hole positions needed for making holes on the edge of the part are usually found out in advance on the part. Usually, the edge distance of the hole site is measured by using a steel plate ruler, an edge distance line is scribed on the surface of the part by using a pencil, and then the hole site is scribed on the edge distance line by using the steel plate ruler again and using the pencil. Because the method does not have a specific tool, the process of marking the edge of the part becomes complicated, especially when facing a large number of parts needing to be drilled at the edge position in the airplane structure, the rapid positioning of hole positions cannot be completed by using a special tool, the progress of subsequent assembly is influenced, the assembly efficiency is lowered, the operation time of workers is prolonged, and the delivery cycle of the airplane is prolonged. Therefore, a special hole-finding device is needed to quickly complete the hole position marking work on the edge of the part.
Disclosure of Invention
In order to solve the problem, the application provides a regional part edge of aircraft assembly looks for hole device is applicable to the hole site of looking for the part edge, simple structure, convenient to use.
The part edge hole site marking device is characterized in that a body of the marking device is of a flat plate structure, one side of a flat plate is a reference surface, a scale indicating block perpendicular to the reference surface of the flat plate is arranged on the reference surface of the flat plate, and the surface of the scale indicating block is provided with dimension scales far away from the reference surface.
And the middle part of the scale indication block is provided with a marking groove.
The scale indication block is L-shaped, the vertical edge of the scale indication block is attached and fixed on the flat plate reference surface, and the horizontal edge of the scale indication block is provided with size scales far away from the flat plate reference surface.
The beneficial effect of this application lies in: 1) the scale marks can provide length information for an operator, and the middle of the scale indication block is provided with a marking groove which can provide a drilling or marking passage for a drill bit or a pencil.
This application has solved assembly region part edge hole site marking efficiency. Firstly, according to different product structures, selecting a proper scale indication block, enabling the flat end face of the marking device to be tightly attached to the edge area of the part, enabling the lower end face of the L-shaped scale indication block to be close to the upper surface of the part and be tightly attached to the upper surface, and according to the scales on the scale indication block, selecting a proper pencil to carry out marking operation through a marking groove. The device solves the problems of poor precision, instability and low equivalent rate of repeated measurement in the marking process of a common steel plate ruler, is convenient to use and easy to operate, improves the assembly efficiency of an assembly site, and reduces the operation time of workers.
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings
Drawings
FIG. 1 is a schematic view of a scribing device for edge holes of a part
The numbering in the figures illustrates: 1 flat plate, 2 scale indication blocks, 3 marking grooves, 4 pencils and 5 size scales.
Detailed Description
Referring to the attached drawings, the body of the part edge hole site marking device is of a flat plate structure, one side of a flat plate 1 is a reference surface, a scale indication block 2 perpendicular to the reference surface of the flat plate is arranged on the reference surface of the flat plate 1, and size scales 5 far away from the reference surface are arranged on the surface of the scale indication block 2. In the implementation, in order to facilitate marking, a marking groove is arranged in the middle of the scale indication block 2. A marking pencil 4 can be inserted through the groove to mark the edge of the part.
In an implementation, in order to fix the scale indication speed, the scale indication block 2 is preferably in an L shape, a vertical edge of the scale indication block 2 is attached and fixed on a reference surface of the flat plate 1, a horizontal edge of the scale indication block 2 is provided with a size scale 5 far away from the reference surface of the flat plate, a marking groove is positioned on a central line of the horizontal edge of the scale indication block 2, and the length direction of the marking groove is parallel to the length direction of the size scale 5.
When the hole making device is used, the hole making position of the edge area of a part is analyzed, and the scale indication block 2 is fixed at a proper height of the flat plate. The reference surface of the flat plate 1 is close to the edge of a part to be drilled, so that the edge of the part is tightly attached and vertical to the reference surface of the flat plate, and the scale indication block 2 is placed on the upper surface of the edge of the part to be drilled and is tightly attached; selecting a proper pencil 4, and enabling the pencil 4 to penetrate through a marking groove 3 in the middle of the scale indication block; according to the scale information 2 on the scale indication block, combining the hole site information in the part design digifax, adjusting and selecting a proper position through the marking groove 3; and marking hole position marks on the edges of the parts on the surfaces of the parts by using a pencil according to the scale information on the degree indicating block 2.
The scribing device is simple to use and convenient to operate, scribing efficiency is improved, and assembling period is shortened.
