Description

Technical Field

[0001] This utility model belongs to the field of aviation manufacturing and maintenance technology, and relates to a metal shavings collection tool. Background Technology

[0002] During aircraft maintenance, it is necessary to cut and disassemble rivets or screws on certain structural components. During the cutting and disassembly process, due to the lack of methods or tools for collecting metal shavings, metal shavings are scattered inside the aircraft, which are difficult to clean and pose a threat to flight safety. Therefore, it is necessary to develop a metal shavings collection tool to collect the metal shavings generated during the disassembly process and prevent them from scattering inside the aircraft. Utility Model Content

[0003] This utility model provides a metal shavings collection tool that can automatically collect metal shavings while disassembling rivets or screws. The entire operation method is simple and does not require pneumatic or electric devices, improving the feasibility of operation in confined spaces.

[0004] The present invention adopts the following technical solution:

[0005] A metal shavings collection tool has a block-shaped, integrated structure. Its bottom surface is a contact surface for fitting with structural components. Its upper surface is formed into an inclined surface sloping towards the head. A through groove running forward and backward between the bottom and upper surfaces serves as a metal shavings outlet hole. The opening of the metal shavings outlet hole on the upper surface is a working slot hole. A through hole is formed at the working slot hole towards the bottom surface as a contact slot hole for exposing rivets or screws to be cut. The metal shavings collection tool has a thickened base at the tail end, and a circular groove is formed on the end face of the tail end for connecting a metal shavings collection bottle.

[0006] Furthermore, the contact groove hole is a circle with a diameter of 12mm, and the minimum wall thickness of the contact groove hole is 3mm.

[0007] Furthermore, the angle between the inclined surface of the upper surface of the metal shavings collecting tool and the contact surface is 27°.

[0008] Furthermore, the thickened base is a square with chamfered edges and a distance of 32mm between opposite sides, and the metal shavings discharge hole has a rectangular cross-section with a width of 30mm and a height of 10mm.

[0009] Furthermore, the metal shavings collection bottle is inserted into the circular groove at the end face of the thickened base to achieve connection, or the circular groove is threaded to connect with the metal shavings collection bottle via threads.

[0010] In use, first combine the metal shavings collection tool with the metal shavings collection bottle, then fit the contact surface of the metal shavings collection tool against the structural component, so that the rivet or screw to be cut is located in the contact groove hole. Pass the drill bit through the working groove hole and the contact groove hole to cut and disassemble the rivet or screw on the structural component. The metal shavings are collected by entering the metal shavings collection bottle through the metal shavings outlet hole.

[0011] The beneficial effects of this utility model are:

[0012] (1) This utility model adopts an integrated structure, which is convenient to use and can effectively prevent metal shavings from falling into the aircraft. It only requires cleaning the metal shavings in the metal shavings collection bottle, thus avoiding the cleaning work inside the aircraft after the operation is completed.

[0013] (2) The processing method of this utility model is simple and the precision requirements are not high. The size precision requirements of the metal scrap collection bottle connected with it are not high. It only needs to be able to connect with the metal scrap collection tool. The metal scrap collection bottle can also be replaced by a beverage bottle, which does not need to be made and processed separately. Therefore, the metal scrap collection tool has high economic efficiency. Attached Figure Description

[0020] The following description, in conjunction with the embodiments and accompanying drawings, further explains the specific implementation of this utility model, but is not intended to limit this utility model.

[0021] like Figure 1 and Figure 2As shown, a metal shavings collection tool has a block-shaped integrated structure. Its bottom surface is a contact surface 1 for fitting with a structural component 7. Its upper surface is formed with an inclined surface sloping towards the head. A through groove running forward and backward between the bottom and upper surfaces serves as a metal shavings outlet hole 5. The opening of the metal shavings outlet hole 5 on the upper surface is a working slot hole 3. A through hole extending from the working slot hole 3 towards the bottom surface serves as a contact slot hole 2, allowing rivets or screws to be cut to protrude. A thickened base 4 is formed at the tail end of the metal shavings collection tool, with a circular groove on its tail end face for connecting a metal shavings collection bottle 6. Figure 3 .

[0022] Based on the structural characteristics of the object being disassembled, and in order to ensure ease of use for operators and improve tool durability, the metal shavings collection tool is designed in the following ways:

[0023] 1. The contact groove hole 2 is a circle with a diameter of 12mm, and the minimum wall thickness of the contact groove hole 2 is 3mm.

[0024] 2. The angle between the inclined surface of the upper surface of the metal shavings collecting tool and the contact surface 1 is 27°.

[0025] 3. The thickened base 4 is a square with chamfered edges and a distance of 32mm between opposite sides. The metal shavings discharge hole 5 has a rectangular cross-section with a width of 30mm and a height of 10mm.

[0026] 4. The thickened base 4 has a threaded groove in the circular groove at the tail end face, which is connected to the metal shavings collection bottle 6 by the thread.

[0027] In use, first assemble the metal shavings collection tool with the metal shavings collection bottle 6, then attach the contact surface 1 of the metal shavings collection tool to the structural component 7, so that the rivet or screw to be cut is located in the contact groove 2, such as... Figure 4 The drill bit 8 is passed through the working slot 3 and the contact slot 2, as follows: Figure 5 The rivets or screws on the structural component 7 are cut and disassembled, and the metal chips are collected in the metal chip collection bottle 6 through the metal chip outlet hole 5.
