Problems solved by technology

Nowadays, there is no special tool for dismantling the lock body of the small load-bearing lock. Workers often use cutting machines to cut off the flange of the lock body bit by bit. The work efficiency is low, and it is very easy to cut the structural surface of products such as wound covers, which will affect aircraft products. quality

Embodiment Construction

[0022] Attached below Figure 2-4 The present invention is described in further detail:

[0023] Such as figure 2 As shown, the KTCS small-sized load-bearing lock lock body removal tool 100 is an integral structure, which is divided into a top protrusion 4, a hollow cavity 5 and a bottom cutting and flanging part. The top protrusion 4 is the hammering part: the specific size is: D1=10~12, L1=15; the hollow cavity 5 is the middle part to accommodate the KTCS small load-bearing lock body, and the specific size requirements are: D2=d1+1, L2 =L+10; the bottom cutting flanging part consists of two parts, one part is the cutting edge 61, and the other part is the limiting part 62, such as figure 2 , 3 As shown, the specific size is: D3=d2+2 h=δ.

[0024] Note: D1-the diameter of the hammering part; D2-the diameter of the inner cavity in the middle;

[0025] L1 - top height; L2 - cavity height;

[0026] d1-inner diameter of upper lock body; d2-outer diameter of upper lock bod...

Abstract

The invention relates to a KTCS small bearing lock upper lock body removal tool and method for an aircraft access cover. The KTCS small bearing lock upper lock body removal tool applied in the technical field of aircraft assembly process equipment is characterized by comprising a cavity for containing a KTCS small bearing lock body, the open end is provided with a blade with the inner diameter slightly larger than the outer diameter of the flange of an upper lock body, and the blade edge of the blade is used for cutting the flange of the upper lock body. Compared with the prior art, the tool has the following advantages of solving of the removal problem of a KTCS small bearing lock, improving the working efficiency, and ensuring the surface quality of the access cover.

Description

technical field [0001] The invention relates to a tool and a method for removing a KTCS small force-bearing lock body of an aircraft hatch cover, which are applied in the technical field of aircraft assembly technology and equipment. Background technique [0002] KTCS small force-bearing lock is a common connector for connecting the cover of a certain type of aircraft to the airframe. During the installation process, the KTCS upper lock body 1 and the cover 2 are connected in the form of flanging, and the lower lock body is connected to the fuselage by riveting (such as figure 1 As shown), when the lock body of the KTCS small load-bearing lock is damaged during installation and use and needs to be replaced, it is necessary to cut off the flange 3 of the upper lock body, take out the upper lock body, and replace it with a new one. Nowadays, there is no special tool for dismantling the lock body of the small load-bearing lock. Workers often use cutting machines to cut off the ...
