High-precision automatic milling repair device for aviation titanium alloy tube structure

Abstract

The invention discloses a high-precision automatic milling repair device for an aviation titanium alloy tube structure. The device comprises a workbench, an upper installation base, a conveying mechanism, a movable sleeve and a swing frame. The upper installation base is arranged at one end above the workbench, the upper installation base is of an inverted-L-shaped structure, the conveying mechanism is perpendicularly arranged on one side of the workbench, and the two ends above the workbench are provided with shield plates correspondingly. The high-precision automatic milling repair device has the beneficial effects that a fourth motor rolls front and back in a rolling groove through a track, the front-back moving range of an installation head is enlarged, therefore, the machining range of the device for the tube structure is enlarged, a third motor drives a sleeve to turn over front and back through a rotating shaft, a fifth motor drives the installation head to adjust and turn overup and down, therefore, the polishing position of a polishing sleeve for the tube structure is flexibly adjusted, and it is ensured that the device is higher in polishing precision for the titanium alloy tube structure. By means of a rubber pad, abrasion produced during matched working of the device and the tube structure is reduced, and the machining quality of the device for the tube structure is improved.

Description

Technical field [0001] The invention relates to a milling and repairing device, in particular to a high-precision automatic milling and repairing device for aerospace titanium alloy tube structure, belonging to the technical field of milling and repairing device applications. Background technique [0002] Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance and high heat resistance. Titanium alloy tube structures are increasingly used in the aerospace field. [0003] When the titanium alloy tube structure is used, the smoothness and roundness of the tube structure itself are very important. The surface of the tube structure is smooth enough to fit the aerospace parts more accurately and conveniently. When the titanium alloy tube structure is processed, milling is required. The device mills and repairs the titanium alloy tube structure to make the surface of the tube structure more flat and smooth. [0004] T...
