Abstract
The invention aims to provide a tool mechanism for conducting multi-axis machining on middle-sized aviation arc plates. According to the technical scheme, the tool mechanism is composed of middle-inclined pulling frames, edge-inclined pulling frames, inclined-strut frames, middle-strut frames, bottom-strut frames, inclined-supporting frames, middle-supporting frames and inclined-pulling beams. According to the mechanism, the arc plates are placed on a tool, threaded holes for conducting clamping are distributed in the peripheries of the arc plates, the arc plates are pressed tightly through spacers and bolts, after the arc plates are assembled, the arc plates are placed on a horizontal machining center along with the tool, a datum plate is tightly attached to a bed surface, the tool is pressed tightly through a pressing block, and multi-axis machining of the arc plates is achieved through the method. The mechanism is designed for conducting multi-axis machining on middle-sized aviation pieces, in a polyhedron, such as an arc surface, machining process, multi-axis machining of the arc plates can be achieved through the tool, deformation, caused by machining, of the arc plates can be lowered, and production efficiency is greatly improved. The whole tool is formed by group-welding of all parts, the bottom faces of the arc plates are composed of six coplanar datum blocks, the side faces are milled into arc faces so that arc plates can be attached to one another in a fit mode, clamping is facilitated, and thus multi-axis arc surface machining is achieved.
Description
technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a tooling mechanism for multi-axis machining of medium-sized aviation arc plates. Background technique [0002] In modern aerospace production and manufacturing, arc plate processing is an important link in production. In the past, the processing of arc plates used a single-process processing technology, that is, after completing one process, it was transferred to the next process. In this way, a lot of time and labor costs were wasted. The tooling mechanism puts the arc plate on the tooling, and the tooling is distributed around the arc plate with threaded holes for clamping. The arc plate is pressed tightly with gaskets and bolts. After installation, it is placed on the horizontal machining center together to make the reference plate It is firmly attached to the bed surface, and the press block is pressed against the tooling. This method realizes the multi-axi...
