Description

Technical Field

[0001] This invention relates to the field of riveting technology, and more specifically, to a riveting anvil device for confined space assembly of satellite main structure. Background Technology

[0002] The satellite's main structure comprises numerous planar frames, three-dimensional trusses, sandwich panels, and stringers. During assembly, these structures extensively utilize mounting plates and nuts to provide mechanical interfaces. Commonly used mounting plates and nuts are double-eared, with a threaded hole in the center and rivet holes on both sides, used for connection to structural mounting components via rivets. Common local structural forms include... Figure 1 As shown. The rivets used include pull riveting and press riveting. Press riveting includes two methods: using a special tool for clamping and using a small hammer for hammering. Both pull riveting and clamping require special tools, which are relatively large and are greatly affected by the structure of the components being installed and the available operating space. Hammering, on the other hand, is more versatile and widely used in the riveting operations of satellite main structures.

[0003] A common problem in actual riveting operations is the limited space, making it impossible to firmly support the rivet head with a platform, vise, or other suitable tool, which makes riveting difficult. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a riveting anvil device for assembling the main structure of a satellite in a confined space.

[0005] According to the present invention, a confined space rivet-making anvil device for satellite main structure assembly includes a first connecting component, two second connecting components, and a base. The base is connected to a structural plate via the first connecting component and a support plate nut is fixed to the structural plate. The structural plate is provided with two second structural plate holes for assembling rivets. The two second connecting components are disposed on the base and located on both sides of the first connecting component. The locking head of the rivet abuts against the end of the second connecting component. The rivet-making head passes through the structural plate and the support plate nut in sequence and extends to the outside of the support plate nut. The rivet-making head locks the rivet to the support plate nut and the structural plate by striking.

[0006] Preferably, the first connecting assembly includes a center locking screw and an adapter, and the second connecting assembly includes a top anvil screw, a top anvil locking nut, and a top anvil sleeve;

[0007] The base has a first base hole disposed in the middle and second base holes respectively arranged on both sides of the first base hole; the structural plate has a first structural plate hole disposed in the middle and second structural plate holes respectively arranged on both sides of the first structural plate hole.

[0008] The pallet nut has a first pallet hole in the middle and second pallet holes on both sides of the first pallet hole. One end of the center locking screw is a screw head, and the other end passes through the first base hole to connect to one end of the adapter. The other end of the adapter passes through the first structural plate hole and is assembled into the first pallet hole, so that the relative position between the base and the structural plate is determined.

[0009] Preferably, one end of the anvil screw passes through the second base hole and connects to the anvil locking nut, the anvil sleeve is fitted to the other end of the anvil screw, the locking head of the rivet fitted on the second structural plate hole abuts against the end of the anvil sleeve, and the rivet head passes through the second structural plate hole and the second support plate hole in sequence.

[0010] Preferably, the second base hole is a waist-shaped hole so that the position of the anvil screw can be adjusted in the second base hole.

[0011] Preferably, the center locking screw is threadedly connected to the adapter, and the adapter is threadedly connected to the support plate nut.

[0012] Preferably, the anvil screw has a cross-shaped cross-section, and the second base hole does not allow the anvil screw to pass through.

[0013] Preferably, the anvil sleeve has different specifications, so that different specifications of rivets can be quickly adapted by replacing the anvil sleeve with different specifications.

[0014] Preferably, the base is made of 45 steel.

[0015] Preferably, the center locking screw, the top anvil locking nut, the support plate nut, and the rivets are all standard parts, and the structural plate is a component of the satellite's main structure itself.

[0016] Preferably, the side of the top anvil that contacts the rivet is a flat surface.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides a stable and reliable riveting anvil. The base and the anvil sleeve are connected by a central locking screw, an adapter, and a support plate nut. The anvil screw, the anvil locking nut, and the anvil sleeve provide support for the rivet head. The anvil sleeve can be quickly adjusted to adapt to different installation parts by changing the anvil sleeve. It is suitable for relatively small and confined spaces and solves the problems of difficult riveting and poor operational accessibility. Attached Figure Description

[0038] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0039] Considering the good rigidity of the main structure itself, and utilizing the planes and interfaces of the main structure to achieve stable support for the rivet 8 head through a connecting device, this invention provides a confined space rivet-knocking anvil device for satellite main structure assembly. It utilizes the main structure itself, where rivets 8 need to be installed, to provide stable support for the rivet head, such as... Figure 1 , Figure 2As shown, it includes a first connecting component, two second connecting components, and a base 2. The base 2 is connected to the structural plate 9 through the first connecting component and fixes the support plate nut 7 on the structural plate 9. The structural plate 9 is provided with two second structural plate holes 92 for assembling rivets 8. The two second connecting components are both arranged on the base 2 and located on both sides of the first connecting component. The locking head of the rivet 8 abuts against the end of the second connecting component. The rivet head of the rivet 8 passes through the structural plate 9 and the support plate nut 7 in sequence. The rivet head locks the rivet 8 onto the support plate nut 7 and the structural plate 9 by striking.

[0040] Specifically, the first connecting assembly includes a center locking screw 1 and an adapter 6, and the second connecting assembly includes a top anvil screw 3, a top anvil locking nut 4, and a top anvil sleeve 5. The base 2 has a first base hole 21 located in the center and second base holes 22 arranged on both sides of the first base hole 21. The first base hole 21 is the center hole of the base 2. The structural plate 9 has a first structural plate hole 91 located in the center and second structural plate holes 92 arranged on both sides of the first structural plate hole 91. The first structural plate hole 91 is the center hole of the structural plate 9. The support plate nut 7 has a first support plate hole 71 located in the center and second support plate holes 72 arranged on both sides of the first support plate hole 71. One end of the center locking screw 1 is a screw head, and the other end passes through the first base hole 21 and connects to one end of the adapter 6. The other end of the adapter 6 passes through the first structural plate hole 91 and is assembled into the first support plate hole 71, so that the relative position between the base 2 and the structural plate 9 is determined.

[0041] One end of the anvil screw 3 passes through the second base hole 22 and connects to the anvil locking nut 4. The anvil sleeve 5 is assembled to the other end of the anvil screw 3. The locking head of the rivet 8, which is assembled on the second structural plate hole 92, abuts against the end of the anvil sleeve 5. The side of the anvil sleeve 5 that contacts the rivet 8 is preferably a flat surface. The rivet head of the rivet 8 passes through the second structural plate hole 92 and the second support plate hole 72 in sequence. The rivet head locks the rivet 8 onto the support plate nut 7 and the structural plate 9 by striking.

[0042] The present invention uses the base 2 as a force transmission and dimensional reference. In cooperation with the structural plate 9 and connecting components, the device can ultimately support the head of the rivet 8 through the anvil screw 3, the anvil locking nut 4, and the anvil sleeve 5.

[0043] The center locking screw 1 is fitted with an adapter 6 via an end thread. The adapter 6 is connected to the tray nut 7 via a thread. Different sizes of tray nuts 7 can be quickly adapted by replacing the adapter 6 with different sizes.

[0044] The anvil screw 3 is connected to the base 2 by means of the anvil locking nut 4. The second base hole 22 is a waist-shaped hole, which allows the position of the anvil screw 3 to be adjusted in the second base hole 22. It can be moved in the waist-shaped groove of the base 2 to adapt to different rivet hole positions.

[0045] The anvil sleeve 5 has different specifications. The anvil screw 3 uses the anvil sleeve 5 installed at the end to support the head of the rivet 8. Different specifications of rivets 8 can be quickly adapted by replacing the anvil sleeve 5 with different specifications.

[0046] The base 2 is made of 45 steel, which ensures sufficient rigidity and dimensional accuracy to ensure proper installation and effective clamping.

[0047] This invention, while ensuring rigidity and ease of use, features a compact layout and small overall size, making it adaptable to the operational needs of various confined spaces in satellite main structures. The connection points of the central hole and rivet holes in this invention are equipped with quickly removable and replaceable parts, accommodating different sizes of mounting components.

[0048] In this embodiment, the device is assembled from multiple parts. The center locking screw 1, the top anvil locking nut 4, the support plate nut 7, and the rivet 8 are all standard parts. The structural plate 9 is a component of the satellite's main structure itself. The remaining parts are non-standard parts obtained by milling.

[0049] The assembly principle of this invention is as follows:

[0050] like Figure 1 As shown, align the center hole of the support plate nut 7 with the center hole of the structural plate 9, insert the rivet 8, and pass the adapter 6 through the center hole of the structural plate 9, i.e., through the first structural plate hole 91, and screw it into the center hole of the support plate nut 7 and the first support plate hole 71 to lock it. Install and lock the two sets of top anvil screws 3 and top anvil sleeves 5 and insert them into the waist-shaped groove of the base 2. Install the top anvil locking nut 4, wherein the top anvil locking nut 4 is not locked, leaving a small gap for position adjustment. The main assembly is complete. Align the center hole of the base 2 with the mounting hole of the adapter 6, pass the center locking screw 1 through the center hole of the base 2 and screw it into the threaded hole of the adapter 6, but do not lock it. Adjust the position of the two sets of top anvil screws 3 so that the top anvil sleeve 5 and the rivet 8 head are aligned and fit together. Preferably, the top anvil sleeve 5 and the rivet 8 are arranged concentrically. Lock the top anvil locking nut 4, and then lock the center locking screw 1 to complete the installation.

[0051] While ensuring rigidity and ease of use, this invention features a compact layout and small overall size, making it suitable for operation in various confined spaces on the satellite's main structure. The connection points with the center hole and rivet holes are equipped with parts that can be quickly disassembled and replaced, allowing it to accommodate different specifications of installation components.
