Description

Technical Field

[0001] This utility model relates to the field of top iron technology, specifically a top iron device for aircraft riveting. Background Technology

[0002] During the riveting process of aircraft, a large number of rivets are used to connect and fix the aircraft structure and skin. When workers drive the rivets, one end is used to hit the rivet head with a rivet gun, while the other end is supported by an iron block until the rivet is riveted.

[0003] For example, the existing utility model patent CN203804128U proposes a top iron device for aircraft riveting. This utility model consists of a housing, a top iron that can reciprocate along the slide rail inside the housing, a bolt fitted with a spring, and a positioning pin. During operation, the worker holds the housing, and the top iron moves up and down along the slide rail under the combined action of the rivet and the spring, absorbing the vibration caused by the impact of the rivet gun.

[0004] As in the above technical solution, since the overall length of the shell and the top iron is fixed, when the riveting position is in a deep concave cavity of the aircraft (such as inside the closed box beam of the vertical tail or horizontal tail), the top iron cannot form effective support by simply holding the shell when it is inserted into the concave cavity, and it is difficult to accurately adjust the position of the top iron to match the rivet installation area; thus, there are problems of difficulty in supporting the top iron and difficulty in accurately adjusting the position of the top iron. Utility Model Content

[0005] In view of the technical problems in the prior art, the present invention provides a top iron device for aircraft riveting, which aims to solve the problems of difficulty in supporting the top iron and difficulty in accurately adjusting the position of the top iron when riveting deep concave areas of aircraft.

[0006] A top iron device for aircraft riveting includes a top iron assembly and an adjusting member, wherein, The top iron assembly includes a top iron body and a top rod, wherein the top rod is fixedly disposed on the side of the top iron body away from the riveting surface. The adjusting component includes a sliding block, a support component, and a first fixing knob; The sliding block is connected to the top rod; The support is slidably connected to the sliding block and is used to adjust the position of the top iron body. Both ends of the support extend to the inner wall of the processing area to form a fixed support. The first fixing knob is located at the support corresponding to the sliding block and is used to lock the relative position of the support and the sliding block.

[0007] Optionally, the support member includes a support screw and a seat pad, wherein, The support screw passes through the sliding block and is slidably connected to it; The seat pads include two, which are respectively located at both ends of the support screw and are used to abut against the processing area. The seat pads are threadedly connected to the support screw and are used to rotate to extend the support or rotate to retract and release the support.

[0008] Optionally, the top rod is slidably connected to the sliding block for adjusting the support position of the support member.

[0009] Optionally, the support member further includes a second fixing knob, which is located at the position of the sliding block corresponding to the top rod, and is used to lock the relative position of the sliding block and the top rod.

[0010] Optionally, a stabilizing mechanism may also be included, which comprises a fixing block and a fixing screw, wherein, The fixing block is fixedly installed at the end of the top rod away from the top iron body; The fixing screw slides through the fixing block and is threadedly connected to the sliding block; it is used to constrain the warping deformation of the top rod through the rigid connection between the fixing screw and the sliding block.

[0011] Optionally, the stabilizing mechanism also includes an extension rod and a connecting knob, wherein, The extension rod is detachably inserted into the side of the fixing block away from the top rod; The connecting knob is located at the corresponding extension rod of the fixing block and is used to lock the extension rod.

[0012] Optionally, the stabilizing mechanism also includes a handle and a spring, wherein, The handle is slidably sleeved on the end of the extension rod away from the fixed block, and the handle has a limit sliding cavity corresponding to the fixed block; The spring is located in the limiting sliding cavity and abuts against the end of the extension rod to buffer the relative movement between the handle and the extension rod.

[0013] Optionally, the top iron assembly further includes reinforcing ribs, which are multiple in number and are arranged around the periphery of the top rod and connect the top rod to the top iron body.

[0014] Compared with the prior art, the top iron device for aircraft riveting provided by this utility model has the following advantages: (1) The top iron assembly and the adjusting parts are integrated into an "internal support" structure. The sliding block can move on the top rod with the top iron body. The two ends of the support are directly pressed against the inner wall of the aircraft cavity. The support is then locked with the first fixing knob, thereby obtaining precise and stable support. At the same time, it saves the shaking and fatigue of hand fixing, and significantly improves the riveting stability and safety.

[0015] (2) By supporting the screw and the threaded seat at both ends, the worker can quickly tighten the top iron in cavities of different widths by simply rotating it and retract it at any time. The sliding cooperation between the sliding block and the top rod allows the top iron body to move back and forth for coarse adjustment. The second fixing knob locks the sliding block firmly on the top rod to prevent displacement during impact. The multiple reinforcing ribs around the top rod connect the top rod and the top iron body into a high-rigidity whole, thus achieving a stable, accurate and durable rivet top iron in the deep concave cavity of the aircraft.

[0016] (3) By setting a stabilizing mechanism, the tail end of the top rod is connected to the sliding block through the fixing block, fixing screw and sliding block to limit the tail end of the top rod, making it easier to stabilize the tail end of the top rod; at the same time, the detachable extension rod can be extended or shortened at any time according to the cavity depth, and the connecting knob can be locked by turning it. The sliding handle at the end of the extension rod has a built-in spring, which turns the recoil force into elastic buffer, so that the worker can hardly feel the vibration at the gripping part, which protects the wrist and ensures that the top iron surface is always in close contact with the rivet, making the riveting process stable, labor-saving and efficient.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 The present application discloses a top iron device for riveting aircraft, which includes a top iron assembly 1 and an adjusting member 2.

[0021] like Figure 1-2 As shown, the top iron assembly 1 includes a top iron body 11 and a top rod 12. The top rod 12 is fixedly disposed on the side of the top iron body 11 away from the riveting surface. The adjusting component 2 includes a sliding block 21, a support component 22, and a first fixing knob 23. The sliding block 21 is connected to the top rod 12. The support component 22 is slidably connected to the sliding block 21 and is used to adjust the position of the top iron body 11. Both ends of the support component 22 extend to the inner wall of the processing area to form a fixed support. The first fixing knob 23 is disposed at the position of the sliding block 21 corresponding to the support component 22 and is used to lock the relative position of the support component 22 and the sliding block 21.

[0022] Specifically, deep within the closed box-type beams such as the vertical and horizontal tail fins, workers only need to insert the top rod 12 along with the top iron body 11 into the riveting position. Then, the sliding block 21 slides along the top rod 12, causing the two ends of the support member 22 to abut against the inner wall of the cavity. Finally, tightening the first fixing knob 23 forms an "internal support" rigid fulcrum. The top iron body 11 does not require workers to hold it for support, which eliminates the swaying caused by insufficient arm length. At the same time, the support member 22 is slidably connected to the sliding block 21, which can maintain a precise fit with the rivet end face in the processing area, significantly improving the riveting stability and safety, while reducing labor intensity.

[0023] In some embodiments, such as Figure 1-2 As shown, the support member 22 includes a support screw 221 and a seat 222. The support screw 221 passes through the sliding block 21 and is slidably connected to it. There are two seat pads 222, which are respectively disposed at both ends of the support screw 221 and are used to abut against the processing area. The seat pads 222 are threadedly connected to the support screw 221 and are used to rotate to extend the support or rotate to retract and release the support.

[0024] Specifically, when the cavity width changes, the worker only needs to rotate the seat pads 222 on both sides to adjust the extension length simultaneously or individually, so that the support screw 221 and the cavity wall can be reliably tightened quickly; when retracting, rotating the seat pads 222 in the opposite direction will retract the screw. The entire adjustment process does not require additional tools, and the disassembly and assembly are convenient, ensuring that the top iron device can be quickly adapted to different specifications of aircraft structures, and achieve stable, accurate and durable riveting top iron operations.

[0025] In some embodiments, such as Figure 1-2 As shown, the top rod 12 is slidably connected to the sliding block 21 and is used to adjust the support position of the support member 22; the support member 22 also includes a second fixing knob 223, which is located at the position of the sliding block 21 corresponding to the top rod 12 and is used to lock the relative position of the sliding block 21 and the top rod 12.

[0026] Specifically, after a sliding pair is set between the top rod 12 and the sliding block 21, the top iron body 11 can move back and forth along the axis of the top rod 12. Workers can make rough adjustments according to the rivet arrangement or the difference in wall panel thickness to ensure that the center of the top iron is aligned with the center of the rivet. After the position of the top iron body 11 is adjusted, tightening the second fixing knob 223 will completely lock the sliding block 21 and the top rod 12, preventing the sliding block 21 from slipping when the rivet gun impacts, and ensuring that the top iron surface is always in close contact with the rivet end face. Rigid locking eliminates displacement error, making the riveting process more stable and the rivet forming quality consistent.

[0027] In some embodiments, such as Figure 1 , Figure 3 As shown, a top iron device for aircraft riveting also includes a stabilizing mechanism 3. The stabilizing mechanism 3 includes a fixing block 31 and a fixing screw 32. The fixing block 31 is fixedly disposed at the end of the top rod 12 away from the top iron body 11. The fixing screw 32 slides through the fixing block 31 and is threadedly connected to the sliding block 21. It is used to constrain the warping deformation of the top rod 12 through the rigid connection between the fixing screw 32 and the sliding block 21.

[0028] Specifically, under the continuous impact of the rivet gun, the top rod 12 is prone to bending or warping and other unstable situations. Here, a fixing screw 32 is set to tighten the fixing block 31 and the sliding block 21 into one, forming a "pull rod" type rigid constraint, which significantly suppresses the deformation of the top rod 12. The worker only needs to tighten the fixing screw 32 to achieve the tail limit, ensuring that the top iron body 11 is always perpendicular to the rivet axis, avoiding rivet damage caused by skewing, and making subsequent operations more labor-saving.

[0029] In some embodiments, such as Figure 1 , Figure 3 As shown, the stabilizing mechanism 3 also includes an extension rod 33 and a connecting knob 34. The extension rod 33 is detachably inserted into the side of the fixing block 31 away from the top rod 12. The connecting knob 34 is located on the fixing block 31 corresponding to the extension rod 33 and is used to lock the extension rod 33.

[0030] Specifically, when faced with cavities of different depths, workers can quickly insert or remove the extension rod 33 and lock it with a turn of the connecting knob 34 to instantly increase or decrease the overall length. This modular structure not only expands the applicability of the device but also facilitates transportation and storage, ensuring that riveting operations can still be completed efficiently in narrow or extremely deep spaces. At the same time, the extension rod 33 also makes it easy for operators to manually support it.

[0031] In some embodiments, such as Figure 1 , Figure 4As shown, the stabilizing mechanism 3 also includes a handle 35 and a spring 36. The handle 35 is slidably sleeved on the end of the extension rod 33 away from the fixed block 31. The handle 35 has a limiting sliding cavity 301 corresponding to the fixed block 31. The spring 36 is disposed in the limiting sliding cavity 301 and abuts against the end of the extension rod 33 to buffer the relative movement between the handle 35 and the extension rod 33.

[0032] Specifically, a handle 35 for shock absorption is installed at the operator's support point. When the rivet gun impact generates a reaction force, the spring 36 is compressed in the limiting sliding cavity 301, absorbing and attenuating the vibration and reducing the impact on the worker's hand. The sliding handle 35 always maintains a flexible connection with the extension rod 33, which protects the wrist and ensures that the top iron surface is always in close contact with the rivet.

[0033] In some embodiments, such as Figure 1 As shown, the top iron assembly 1 also includes reinforcing ribs 13, which include multiple ribs and are arranged around the periphery of the top rod 12 and connect the top rod 12 and the top iron body 11. The arrangement of the reinforcing ribs 13 forms a ring-shaped reinforcing structure between the top rod 12 and the top iron body 11, which significantly improves the connection rigidity and prevents local deformation or fatigue cracks caused by repeated impacts. The high rigidity of the whole ensures that the top iron body 11 can still maintain the accurate position and shape during long-term, high-intensity riveting operations, extend the service life of the device, and maintain stable riveting quality.
