Mirror image milling follow-up jacking support device and method for thin-walled parts

Abstract

The invention discloses a mirror image milling follow-up jacking support method and device for thin-walled parts. The mirror image milling follow-up jacking support method and device for the thin-walled parts are used for solving the problem that in an existing milling machining process of large-sized thin-walled parts, machining vibration and local deformation easily occur to the workpieces. According to the technical scheme, the special mechanical-arm-shaped jacking support device is adopted and comprises a jacking support arm rotating box, a main jacking support arm, a jacking support headrotating box, a main jacking support head, an auxiliary jacking support arm, an auxiliary jacking support head rotating box, an auxiliary jacking support head, a servo motor and the like. In the milling machining process of the thin-walled parts, the jacking support heads of the jacking support device conduct follow-up support from the reverse surfaces of the thin-walled parts according to machining cutter trajectory program coordinates, the normal thickness compensation of the support surface is achieved through online thickness monitoring at the same time, the machining deformation is avoided, the machining stability is improved, and the machining precision and quality of the thin-walled parts are ensured.

Description

Technical field: [0001] The invention relates to a mirror image milling machining jacking method and device, in particular to a mirror image milling follow-up jacking method and device for a thin-walled part. Background technique: [0002] When processing large thin-plate parts, when the tool applies cutting force to the suspended area between the clamping points, especially the thin skin, the skin of this part will inevitably vibrate, so that the milling depth and surface roughness cannot be adjusted. control, it cannot meet the requirements of chemical milling concave surfaces with different depths. However, chemical milling has inherent disadvantages such as chemical pollution, high power consumption, and consumption of aluminum that cannot be recycled, which has become a problem for the industry. For the processing of a new generation of titanium alloy skins, chemical milling also needs to take special measures for fire and explosion protection, which increases process ...
