Description

Technical Field

[0001] The present invention belongs to the technical field of rectangular spray painting protection positioning for aircraft parts, and relates to an adjustable rectangular area spray painting protection positioning tool. Background Art

[0002] Aircraft electrical bonding technology refers to the reliable electrical connection with low impedance paths between structural components of an aircraft, equipment, pipelines, accessories and other components. When harmful charges (such as static electricity, lightning, induced current) occur on the aircraft, these charges can be transferred away through the electrical bonding path to avoid subsequent hazards. At present, a large number of electrical bonding parts in the aircraft manufacturing industry need to be spray painted for protection. The protection dimensions of such parts vary, there are many item numbers, and the quantity of each item is small. The common spray painting protection form is a regular rectangular area around a circular hole. At present, the conventional method for spray painting protection is to manually cut the protection tape according to the parameters of the drawing or digital model and paste the tape at the protection position.

[0003] At present, the following problems will occur when performing rectangular area spray painting protection in the conventional way:

[0004] (1) There are many types and item numbers of aircraft parts, and the quantity of each item is small. The spray painting protection dimensions of rectangular areas vary, and it is impossible to produce protection tapes in batches. Only manual cutting of the protection tape is used, lacking an effective positioning auxiliary tool, resulting in low work efficiency.

[0005] (2) Most of the drawings of aircraft models are two-dimensional or paper drawings. After measuring the protection position parameters on the drawings, the tape is manually cut, resulting in large errors in the protection tape.

[0006] (3) When the tape is pasted at the protection position of the part, since the tape blocks the operator's sight, it is easy to cause deviation in the tape sticking position. It is found that the protection position is inaccurate during the subsequent assembly process, and the part needs to be reworked, affecting product quality and restricting production efficiency. Summary of the Invention

[0007] In order to solve the above problems existing in the prior art, the present invention provides an adjustable rectangular area spray painting protection positioning tool, which can quickly locate through the holes in the protection area by changing the position of the positioning tool, is applicable to spray painting protection treatment of rectangular areas of various sizes, reduces the tape cutting time, improves the accuracy of the outer shape dimensions of the tape, ensures product quality, and improves production efficiency.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is:

[0009] An adjustable rectangular area spray painting protection positioning tool, the positioning tool includes an outer frame 1, a rectangular moving frame 2, a square moving frame 3 and a circular disc 4. (See Figure 1 )

[0010] The outer frame 1 has an overall square frame structure, and the inner hole wall of the square is a groove structure (see Figure 2 ). The inner hole size of the outer frame 1 is the long side size of a common rectangular spray paint protection area. Dimension scales are marked beside the inner hole on the outer frame 1 for positioning the position of the rectangular moving frame 2.

[0011] The rectangular moving frame 2 has an overall long strip structure (see Figure 3 ). Its inner hole is also strip-shaped and is arranged along the length direction of the rectangular moving frame (2). The inner hole wall is a groove structure. The thickness of the rectangular moving frame 2 matches the width of the groove structure of the outer frame 1, and its long side size matches the inner hole size of the square of the outer frame 1. Place the rectangular moving frame 2 in the groove structure of the outer frame 1 so that it can move up and down along the groove without falling out (see Figure 4 ). Dimension scales are marked beside the inner hole on the rectangular moving frame 2 for positioning the position of the square moving frame 3.

[0012] The outer part of the square moving frame 3 is square and the inner hole is circular. The inner hole wall is a groove structure (see Figure 5 ). The thickness of the square moving frame 3 matches the width of the groove structure of the rectangular moving frame 2, and its side length matches the short side length of the inner hole of the rectangular moving frame 2. Place the square moving frame 3 in the groove structure of the rectangular moving frame 2 so that it can move along the groove length direction within the rectangular moving frame 2 without falling out (see Figure 6 ).

[0013] The size of the disc 4 is the size of a circular hole within a common rectangular spray paint protection area, and its outer diameter matches the circular inner hole size of the square moving frame 3. The disc 4 is grooved along the radius (see Figure 7 ), and dimension scales are marked beside the groove for reading the required radius. Place the disc 4 in the groove structure of the inner hole of the square moving frame 3 so that it can rotate 360° along the groove within the square moving frame 3 (see Figure 8 ).

[0014] Furthermore, the outer frame 1, the rectangular moving frame 2, the square moving frame 3, and the disc 4 are made of aluminum alloy plates. Among them, the first three are all connected by bolts for the plates.

[0015] In use, the operator uses this positioning tool according to the drawing or digital model parameters, moves the rectangular moving frame 2 up and down, and uses the dimension scales beside the inner hole of the outer frame 1 and on the outer frame of the rectangular moving frame 2 to draw a rectangular protection area on the adhesive tape; the up and down movement of the rectangular moving frame 2 is used in conjunction with the left and right movement of the square moving frame 3 to align the center of the circular wafer 4 with the center of the inner hole of the protection area. According to the radius of the hole, through the scale on the slot of the circular wafer 4, the circular wafer 4 is rotated 360° along the slot at the same position to draw the hole area; according to the part hole position parameters, the above operations are repeated to draw multiple internal hole positions on the rectangular area. After the adhesive tape is cut into the rectangular area, the holes are cut at the same time; using the positioning of multiple holes on the adhesive tape, the rectangular adhesive tape is pasted on the part protection area.

[0016] Advantages of the present invention:

[0017] ① In the present invention, the rectangular moving frame, the square moving frame, and the circular wafer can move along the slots, realizing the adjustability of the internal structure of the tool, facilitating the accurate positioning of the rectangle and the inner hole position, and the operation is simple.

[0018] ② The outer frame, the rectangular moving frame, the square moving frame, and the circular wafer of the present invention are all provided with dimension scales, and the adjusted position can be applied to the spray painting protection of rectangular areas of various sizes, with a wide range of applications.
