Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance technology, specifically to a sleeve tooling for ensuring the verticality of drilling. Background Technology

[0002] In passenger-to-freighter conversion projects for civil aircraft, fuselage structural modifications involve extensive drilling operations with high-strength metals or composite materials. Because cargo holds require the installation of cargo securing systems, reinforced frames, and other components, load-bearing structural members tens of millimeters thick are often added to the existing passenger cabin structure. In traditional drilling processes, operators must manually maintain the drill bit's verticality. However, in areas with multi-layered thick plates or irregularly shaped structures, drill bit skew can easily cause deviations in the hole's axis, which can range from affecting bolt connection strength to triggering structural fatigue cracks. Utility Model Content

[0003] The purpose of this utility model is to provide a sleeve tooling for ensuring the verticality of drilling, which can ensure the verticality of the drilling when drilling structural parts on the machine body.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0005] A sleeve fixture for ensuring drilling perpendicularity includes a main body with a sealed top and an open bottom. The bottom surface of the main body has a support surface for supporting itself on a structural component. A through hole is provided on the top surface of the main body for a drill rod to pass through, and the through hole is perpendicular to the support surface. The main body is a hollow cylinder. Its function is to ensure the perpendicularity of the drill hole by using the support surface to allow the main body to fit snugly against the surface of the structural component and by using the through hole to prevent the drill rod from tilting excessively during drilling.

[0006] Furthermore, the top surface of the main body is arranged parallel to the supporting surface.

[0007] Furthermore, a support platform is provided on the top surface of the main body, and a through hole is provided on the support platform, which is coaxially arranged with the through hole.

[0008] Furthermore, the inner diameter of the through hole matches the maximum outer diameter of the drill rod. Its function is to ensure that the drill rod and the through hole are coaxially aligned during drilling, thus ensuring that the drill rod is perpendicular to the support surface, through the design of the dimensional relationship between the through hole and the drill rod.

[0009] Furthermore, the inner diameter of the through hole is greater than or equal to the inner diameter of the through hole.

[0010] Furthermore, the side wall of the main body is provided with a chip discharge port for discharging drill cuttings.

[0011] Furthermore, the chip discharge port is connected to the support surface. Its function is to directly discharge the drill chips generated on the drilling surface of the structural component.

[0012] Furthermore, a thickened layer is provided on the outer wall of the main body. Its function is to enhance the overall structural strength of the main body through the addition of the thickened layer.

[0013] Furthermore, the thickened layer is located on the side of the chip discharge port away from the support surface. Its function is to facilitate gripping the thickened layer during operation by positioning it correctly.

[0014] Furthermore, the outer wall of the thickened layer is provided with anti-slip texture. The purpose of this is to increase the friction between the thickened layer and the hand, making it easier to firmly hold the main body and keep the supporting surface in close contact with the drilling surface.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting up a support surface, the main body can be closely attached to the surface of the structural component. By setting up through holes, the drill rod of the electric drill can be prevented from tilting excessively during drilling, thereby ensuring the verticality of the drill hole.

[0017] 2. By designing the relationship between the dimensions of the through hole and the drill rod, the drill rod and the through hole are ensured to be coaxial during the drilling process, that is, the drill rod is ensured to be perpendicular to the support surface. Attached Figure Description

[0024] Example 1

[0025] A sleeve tooling used to ensure borehole perpendicularity, such as Figure 1 As shown, the main body 1 includes a top seal and a bottom opening, as... Figure 2 As shown, the bottom surface of the main body 1 is provided with a support surface 2 for supporting the structural component, and the top surface of the main body 1 is provided with a through hole 3 for the drill rod to pass through. The through hole 3 is perpendicular to the support surface 2. The main body 1 is in the shape of a hollow cylinder. Its function is that, through the setting of the support surface 2, the main body 1 can be closely attached to the surface of the structural component, and through the setting of the through hole 3, the drill rod of the electric drill can be prevented from tilting excessively during drilling, thereby ensuring the verticality of the drill hole.

[0026] Specifically, such as Figure 1 As shown, the top surface of the main body 1 is parallel to the support surface 2. Its function is to ensure that the mounting surface of the drill rod on the electric drill is in close contact with the top surface of the main body 1 through the spatial relationship between the top surface of the main body 1 and the support surface 2. Since the drill rod is perpendicular to the mounting surface on the electric drill, this ensures that the drill rod is perpendicular to the support surface 2.

[0027] Specifically, such as Figure 1 As shown, a support platform 4 is provided on the top surface of the main body 1, and a through hole 5 is provided on the support platform 4, which is coaxially arranged with the through hole 3. Its function is to support the drill rod mounting surface on the electric drill through the support platform 4, making it safer to use.

[0028] Specifically, such as Figure 1As shown, the inner diameter of the through hole 5 matches the maximum outer diameter of the drill rod. Its function is to ensure that the drill rod and the through hole 5 are coaxially aligned during the drilling process by designing the dimensional relationship between the through hole 5 and the drill rod, that is, to ensure that the drill rod is perpendicular to the support surface 2.

[0029] Specifically, such as Figure 1 As shown, the inner diameter of the through hole 3 is greater than or equal to the inner diameter of the through hole 5.

[0030] Specifically, such as Figure 1 As shown, a chip discharge port 6 for discharging drill cuttings is provided through the side wall of the main body 1.

[0031] Specifically, such as Figure 1 As shown, the chip discharge port 6 is connected to the support surface 2. Its function is to directly discharge the drill chips generated on the drilling surface of the structural component.

[0032] Specifically, such as Figure 1 As shown, a thickened layer 7 is provided on the outer wall of the main body 1. Its function is to enhance the overall structural strength of the main body 1 by providing the thickened layer 7.

[0033] Specifically, such as Figure 1 As shown, the thickened layer 7 is located on the side of the chip discharge port 6 away from the support surface 2. Its function is to facilitate gripping the thickened layer 7 during operation by positioning it correctly.

[0034] Specifically, such as Figure 1 As shown, the outer wall of the thickened layer 7 is provided with anti-slip textures 8. The function of these textures is to increase the friction between the thickened layer 7 and the hand, making it easier to hold the main body 1 firmly and keep the supporting surface 2 in close contact with the drilling surface.

[0035] The working principle of this embodiment is explained as follows: When drilling is required, the support surface 2 is pressed tightly against the drilling surface, the anti-slip texture 8 is gripped firmly, and the drill rod of the electric drill is passed through the through hole 5. During the drilling process, the support surface 2 is kept pressed tightly against the drilling surface to ensure the verticality of the drilling.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
