Description

Technical Field

[0001] This utility model relates to aircraft fastener removal technology, specifically to an auxiliary pressing and collecting tool for fastener removal. Background Technology

[0002] In aircraft component structural repair, it is frequently necessary to replace fasteners, with solid rivets being the most common replacement. For example... Figure 3 The diagram shows a solid rivet 6, which includes a rivet head 6.1 at the front end, an uphead 6.3 at the rear end, and a rivet shank 6.2 connecting the rivet head 6.1 and the uphead 6.3.

[0003] Currently, the main methods used by frontline workers to remove solid rivets are: First, as follows... Figure 4 As shown, use a twist drill 12 to drill the rivet head 6.1; then as... Figure 5 As shown, use a punch 9 to pry off the rivet head 6.1; then as... Figure 6 As shown, wooden top blocks or nail irons 13 are used to support the surface of the aircraft component 11 adjacent to the head 6.3, and finally the head 6.3 along with the rivet rod 6.2 is punched off using a punch 9.

[0004] However, the above method of removing solid rivets has two shortcomings:

[0005] 1. When wooden blocks or nails are used to support the surface of aircraft components adjacent to the support head, only one of the four directions around the support head will provide support for the aircraft component surface, while the other three directions will not be supported. Therefore, under uneven stress, it is very easy to cause structural deformation or surface damage to the aircraft component.

[0006] Second, due to the impact force of the punch, the rivet head along with the rivet rod will be thrown to a considerable distance. Therefore, after the removal of solid rivets is completed, workers will have to spend a lot of time collecting the scattered solid rivet heads along with the rivet rods from a distance. Utility Model Content

[0007] The purpose of this invention is to provide an auxiliary pressing and collection tool for fastener removal, which can better ensure that the structure of aircraft parts does not deform during the fastener removal process, and can collect the fastener parts punched out by the punch.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] An auxiliary pressing and collecting tool for fastener removal is characterized by comprising an aluminum alloy top block, a metal connecting tube, a fastener collecting bag, and a rubber outer skin. The aluminum alloy top block includes a handheld part and a pressing part located at the front end of the handheld part for pressing against the surface of aircraft parts. The aluminum alloy top block has a fastener collecting channel, with the inlet of the fastener collecting channel located at the front end of the pressing part and the outlet of the fastener collecting channel located on the surface of the handheld part. One end of the metal connecting tube is connected to the outlet of the fastener collecting channel. The opening of the fastener collecting bag is fitted over the other end of the metal connecting tube, and the rubber outer skin covers the outer surface of the handheld part.

[0010] A further technical solution of this utility model is: the end of the metal connecting tube that connects to the fastener collection bag is in the shape of a flared mouth.

[0011] A further technical solution of this utility model is: the hand-held part is cylindrical, and the top-pressing part is square columnar.

[0012] A further technical solution of this utility model is: the front end surface of the top pressing part is a top pressing plane.

[0013] A further technical solution of this utility model is as follows: the outlet of the fastener collection channel is located on the lower surface of the handheld part, the metal connecting tube is in a vertical state, the upper end of the metal connecting tube is connected to the outlet of the fastener collection channel, and the bag mouth of the fastener collection bag is fitted onto the lower end of the metal connecting tube.

[0014] A further technical solution of this utility model is: the fastener collection channel includes a horizontal circular hole and a vertical circular hole that communicates with the rear end of the horizontal circular hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When in use, this utility model can press the front end face of the pressing part against the surface of the aircraft parts. The fasteners to be removed are located in the middle of the entrance of the fastener collection channel. The front end face of the pressing part can support the four directions around the fastener, thereby better ensuring that the structure of the aircraft parts will not be deformed during the fastener removal process.

[0017] Furthermore, the fastener parts punched out by the punch will enter the fastener collection channel under the force of the punch, and finally fall into the fastener collection bag to complete the collection. Workers no longer need to spend time collecting fastener parts that are scattered in a distance, which improves efficiency.

[0018] The auxiliary pressing and collecting tool of this utility model is suitable for removing permanent fasteners such as rivets, pull screws, high-lock bolts and locking screws, and can be promoted throughout the industry. Attached Figure Description

[0031] Example:

[0032] like Figure 1 The image shows an auxiliary pressing and collecting tool for fastener removal in this embodiment, which includes an aluminum alloy top block 1, a metal connecting pipe 2, a fastener collecting bag 3, and a rubber outer skin 5.

[0033] The aluminum alloy top block 1 includes a handle portion 1.2 and a pressing portion 1.1. The handle portion 1.2 is cylindrical, and its dimensions are designed according to the hand size of an adult Chinese male, allowing the worker to easily grip the aluminum alloy top block 1. The pressing portion 1.1 is located at the front end of the handle portion 1.2. The pressing portion 1.1 is a square column with a square cross-section, and its dimensions are designed according to the fastener sizes and spacing of most aircraft components. The front end face of the pressing portion 1.1 is a pressing plane 1.3, which is used to press against the surface of the aircraft component 11 during use.

[0034] The use of aluminum alloy for the top block can effectively avoid the problem of insufficient strength and hardness of wooden top blocks, which are prone to cracking. Compared with nails and iron, the overall weight of the aluminum alloy top block 1 is reduced by more than 50%, which greatly reduces the workload of workers.

[0035] A fastener collection channel 4 is provided inside the aluminum alloy top block 1. In this embodiment, the fastener collection channel 4 includes a horizontal circular hole 4.1 and a vertical circular hole 4.2. The upper end of the vertical circular hole 4.2 is connected to the rear end of the horizontal circular hole 4.1. The front end of the horizontal circular hole 4.1 is the inlet of the fastener collection channel 4, located in the middle of the pressing plane 1.3 of the pressing part 1.1. The lower end of the vertical circular hole 4.2 is the outlet of the fastener collection channel 4, located on the lower surface of the handheld part 1.2.

[0036] The metal connecting pipe 2 is in a vertical position. The upper end of the metal connecting pipe 2 is fixedly connected to the outlet of the fastener collection channel 4 using a conventional structure, such as a threaded connection. The lower end 2.1 of the metal connecting pipe is flared. The opening of the fastener collection bag 3 is fitted over the lower end 2.1 of the metal connecting pipe and tied with a rope.

[0037] The rubber outer skin 5 covers the outer surface of the handheld part 1.2, which is the part that the worker holds during the dismantling process. The rubber outer skin 5 can better protect the worker's hands from vibration injuries caused by impact.

[0038] like Figure 2 As shown, the process of removing solid rivets 6 using the auxiliary pressing and collecting tools of this embodiment is as follows:

[0039] The first step, as in the background art, is to first drill the rivet head 6.1 using a twist drill 12;

[0040] The second step, as in the background art, is to use a punch 9 to pry off the rivet head 6.1;

[0041] The third step is to press the pressing part 1.1 of the aluminum alloy top block 1 onto the surface of the aircraft part 11 corresponding to the head 6.3 of the solid rivet 6 to be removed. The head 6.3 of the solid rivet 6 is located in the middle of the entrance of the fastener collection channel 4. The pressing plane 1.3 of the pressing part 1.1 is in close contact with the surface of the aircraft part 11. The surfaces of the aircraft part 11 in the four directions around the head 6.3 are all pressed by the pressing plane 1.3 of the pressing part 1.1.

[0042] The fourth step involves using a punch 9 to hold the end of the rivet rod 6.2 away from the head 6.3, and then using a hammer 10 to strike the punch 9. Under the impact force, the rivet rod 6.2 and the head 6.3 are punched out together and enter the fastener collection channel 4, and finally fall into the fastener collection bag 3.

[0043] Fifth step: After a large number of solid rivets 6 have been removed and the fastener collection bag 3 is full, untie the rope, take out the rivet rod 6.2 along with the head 6.3, and empty the fastener collection bag 3.

[0044] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
