Problems solved by technology
[0005] The main problems of traditional drilling templates are: 1) For aircraft workpieces of different specifications and forms, different drilling templates need to be used, and the drilling templates are not universal, and one product may require several drilling templates
2) There are structural defects in the drilling template, there is no multi-layer overall tool guiding structure, and the position cannot be adjusted in multiple directions
3) The drilling template lacks a high-precision position feed control device, and there is a problem of unstable machining accuracy, which has great limitations in the application of high-precision aircraft product processing
4) The drilling template uses parallel planar substrates and drilling modules, which cannot be used in the hole-making process of variable-curvature wall panels

Embodiment Construction
[0043]The present invention will be further described in detail below in conjunction with the accompanying drawings. The following description is exemplary and not limiting to the present invention. Any other similar situations also fall within the protection scope of the present invention.
[0044] Such as figure 1 As shown, a template device for hole making includes a flexible drilling template installation base plate adapted to the surface shape of the external part to be holed. The drilling template mounting base plate is replaceable, including various drilling template mounting base plates with the same outer contour but different internal openings, such as Figure 7 The flexible drill module A shown in the installation base plate 7 or as Figure 8 The installation base plate 8 of the flexible drill module B shown in , the opening part of the installation base plate 7 of the flexible drill module A is different from the opening part of the installation base plate 8 of th...

The invention relates to a template device for drilling. The template device comprises a flexible drilling template installing base plate matched with the surface of an external to-be-drilled part in shape, and the flexible drilling template installing base plate comprises opening parts and entity parts. The opening parts are used for containing drilling modules, and the drilling modules are provided with through holes, are further provided with positioning devices and each comprise at least two side faces. The first side faces are connected to fine-adjusting locking modules through drilling template installing plates; and the fine-adjusting locking modules can perform fine relative movement relative to the positions of the entity parts and be locked to the entity parts by finely adjusting the fine-adjusting locking modules. The second side faces of the drilling modules are connected to drilling template fixing frames through drilling template supporting arms, and the drilling template supporting arms and the drilling template fixing frames can be locked through second locking devices.
Description
technical field [0001] The invention relates to a template device for making holes, especially a flexible template device for making holes, especially a flexible template device for making holes on wings. Background technique [0002] At present, it is necessary to use a drilling template to guide the tool to make holes on the product (hole making includes: drilling, reaming, reaming, etc.), and the drilling template drills a number of positioning holes at predetermined positions according to the hole making requirements. After the drilling template is fixed with the workpiece, the workpiece is clamped on the machine tool. When performing hole-making processing, make the drill bit enter the workpiece along the preset hole on the drilling template to make holes on the workpiece. The drilling template plays a good role in guiding and positioning, which is conducive to ensuring the quality of hole-making and improving the efficiency of hole-making. In aircraft assembly The app...
