Technical Field
[0001] This utility model relates to the field of automatic drilling and riveting of aircraft panels, and in particular to an automatic drilling and riveting positioning device for curved panels. Background Technology
[0002] With the development and breakthroughs in aircraft manufacturing technology, more and more inverted curved panels are appearing in aircraft assembly processes. This poses a challenge to automated drilling and riveting. To ensure the positioning stability and processing safety of inverted curved panels during automated drilling and riveting, the product needs to be positioned under the frame, the panel fixed to the drilling and riveting bracket, and tightened on the skin surface using a tensioning device. However, to ensure drilling and riveting quality, it is necessary to ensure that the panel does not shift or move on the drilling and riveting machine frame when the equipment adjusts its normal direction and processes the product. Providing effective support and fastening for the panel is a key element in the automated drilling and riveting positioning of inverted curved panels.
[0003] In summary, there is an urgent need for a recurve-type automatic drilling and riveting positioning device that has a reasonable structure, is easy to position, and can be installed quickly. Summary of the Invention
[0004] This utility model provides a set of recurved automatic drilling and riveting positioning devices with reasonable structure, convenient positioning and quick installation, to solve the problems mentioned above, meet the automatic drilling and riveting requirements of recurved wall panels, fix the product and ensure stability and safety during drilling and riveting.
[0005] To achieve the above objectives, the present invention employs the following technical means:
[0006] An automatic drilling and riveting positioning device for inverted curve wall panels comprises a drilling and riveting bracket, a drilling and riveting clamping plate, a clamping block, a tensioning belt, a lifting hook, and a bracket positioning seat. The drilling and riveting bracket consists of a long main beam, a long secondary beam, an arch beam, and supporting short beams. Two long main beams are located on the long side of the drilling and riveting bracket, and two long secondary beams are located in the center. The main and secondary beams on both sides are connected by supporting short beams to enhance structural rigidity. Two arch beams connect the main and secondary beams on the short side of the drilling and riveting bracket. The drilling and riveting clamping plate is mounted on the two long secondary beams via a base. Positioning blocks are provided on the drilling and riveting clamping plate to fix the product and prevent it from shifting. The clamping block is placed on the upper surface of the product and tightened by a tensioning belt to ensure the positioning stability of the product.
[0007] Furthermore, the drilling and riveting chuck consists of a chuck body, a positioning block, and a positioning base. This utility model has a total of 4 chucks. The chucks are connected to the long secondary beam of the drilling and riveting bracket through the positioning base. Each chuck is equipped with a positioning block and a positioning slider distributed at both ends of the chuck. The positioning block end is in close contact with the product and serves as the positioning edge. The positioning slider end is a movable end that can be moved according to the actual size of the product to secure it.
[0008] Furthermore, the positioning base consists of a connecting pad, positioning pins, and corner brackets. The connecting pad is fixed to the long sub-beam, the corner brackets are connected to the pad, and the clamping plate is fastened to the corner brackets by two positioning pins. The tension band hook consists of a base and a hook, with the tension band pull ring hanging on the hook, and a clamping device used to tighten it to the wall panel.
[0009] Furthermore, the positioning blocks are divided into two categories: movable blocks and fixed blocks. Fixed blocks include positioning blocks and positioning bolts. The bolts secure the positioning blocks to the clamping plate, and the two fixed blocks serve as the positioning ends of the wall panel. Movable blocks are divided into rotating blocks and sliding blocks. The rotating blocks are placed symmetrically with the fixed blocks to jointly fix the short side of the product. Sliding blocks are distributed on both sides of the clamping plate and consist of a fixed base, a slider, and a positioning pin. One side of the clamping plate can only move up and down, serving as the positioning end of the product, while the other side can only move left and right. The slider can be adjusted to fit the product, serving as an auxiliary positioning end.
[0010] Furthermore, the clamping blocks are made of nylon blocks, with a total of 4 blocks placed on the upper side of the card plate. The upper side of the clamping blocks is grooved, and the tensioning band is placed in the groove to tighten it and prevent it from falling off. The lower side of the clamping blocks is set according to the theoretical outer surface of the wall panel, which fits tightly with the wall panel, and rubber is applied to prevent damage to the product.
[0011] Furthermore, the entire drilling and riveting bracket is connected to the equipment frame via a base, and consists of a guide locator, a fixed support, a positioning sleeve, a support base, and a connecting pad. The connecting pad enhances the connection strength between the base and the long main beam. When the drilling and riveting bracket is connected to the frame, the guide locator acts as a guide, and the fixed support connects to the mating interface on the frame, supporting the entire drilling and riveting bracket. The circular hole of the positioning sleeve connects to the cylinder on the frame, restricting the movement of the drilling and riveting bracket.
[0012] Furthermore, the lifting ring consists of a support and a pull ring. The support is connected to the long main beam, with three evenly distributed on each of the two long main beams. The lifting can be completed by connecting the hanging ring to the pull ring.
