Embodiment 1
[0017] Embodiment 1: as figure 1 and figure 2 The shown hole-making tool for a sealing profile includes a transmission pin fixing plate 4 and a limit sleeve fixing plate 2. One side of the limit sleeve fixing plate 2 is provided with a connecting block 5, and the other side is detachably installed with a limit Cover 1, one side of the transmission pin fixing plate 4 is connected to the upper part of the connecting block 5 through a cylindrical pin 7, and the other side is detachably installed with a transmission pin 3 corresponding to the limit sleeve 1. Since the transmission pin fixing plate 4 and the The connection block 5 is rotated and connected, so that the transmission pin 3 can rotate around the cylindrical pin 7 with the spacer sleeve fixing plate 2, and the matching position of the spacer sleeve and the transmission pin is limited.
[0018] Preferably, the transmission pin 3 is in clearance fit with the limit bushing.
[0019] Preferably, the position-limiting sle...

The drilling tool comprises a transmission pin fixing plate and a limiting sleeve fixing plate, a connecting block is arranged on one side of the limiting sleeve fixing plate, a limiting sleeve is detachably installed on the other side of the limiting sleeve fixing plate, and one side of the transmission pin fixing plate is rotationally connected with the upper portion of the connecting block through a cylindrical pin; and a transmission pin corresponding to the limiting sleeve is detachably mounted on the other side of the base. The circumference of the sealing profile is punched by shearing force, holes are easily and conveniently formed in a pressing mode, the problems that holes formed in the sealing profile and holes in corresponding covering caps are not concentric, and the roundness is poor can be effectively solved, the hole forming efficiency is improved, and the sealing profile can be manufactured by replacing limiting sleeves and transmission pins with different diameters. The drilling tool can be suitable for drilling sealing profiles with different diameters, the universality is improved, and the drilling quality and efficiency can be guaranteed.
Description
technical field [0001] The invention belongs to the technical field of aircraft assembly, and in particular relates to a hole-making tool for sealing profiles. Background technique [0002] At present, in order to waterproof and prevent corrosion, the surface structure of the aircraft door cover needs to paste the profile of the sealing material on the aircraft door cover, and the bolt holes on the door cover need to penetrate the sealing profile to install the bolts on the door cover. At present, the method of manual blade cutting is used to open holes on the sealing profile. The method of cutting with a blade is not a round hole at first, and the operator needs to trim it repeatedly. There are many covers and corresponding bolt holes. This method is time-consuming and laborious, and only manual trimming is required. Different concentricity, different sizes, and out-of-roundness will ultimately affect the waterproof performance of the flap. Contents of the invention [...
