Tool for high-speed numerical control milling machining of thin-walled part

Abstract

The invention discloses a tool for high-speed numerical control milling machining of a thin-walled part. The tool comprises a support, a support and two follow-up clamping devices oppositely arrangedon the support, wherein each follow-up clamping device comprises a first linear driving mechanism, a hollow shell, a heating mechanism, a gas supply mechanism, a deformation mechanism and a floating clamp, each deformation mechanism comprises a planar thermoplastic layer and an elastic outer layer wrapping the planar thermoplastic layer, and each floating clamp comprises cylinder bodies, floatingchucks, pistons, a second linear driving mechanism and a closed partition plate. According to the tool, the flexible clamping of the thin-walled part is realized, the thin-walled part can be effectively attached, the clamping deformation of the thin-walled part is effectively avoided, the machining quality of the thin-walled part is improved, clamping of different thin-wall parts can be realized,and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of machining fixtures, in particular to a tooling for high-speed numerical control milling of thin-walled parts. Background technique [0002] Thin-walled parts have the characteristics of light weight, material saving, and compact structure. However, due to poor rigidity and weak strength, thin-walled parts are easily deformed during CNC milling, which increases the shape and position error of thin-walled parts, and it is difficult to ensure thin-walled parts. The processing quality of thin-walled parts, and the existing tooling for thin-walled parts clamping adopts a rigid clamping method, which is easy to cause clamping deformation of thin-walled parts, which affects the dimensional accuracy and shape accuracy of thin-walled parts, thereby affecting thin-walled parts. The processing quality of the parts, while the existing tooling can only be used for the clamping of a single thin-walled part, has a singl...

[0002] Thin-walled parts have the characteristics of light weight, material saving, and compact structure. However, due to poor rigidity and weak strength, thin-walled parts are easily deformed during CNC milling, which increases the shape and position error of thin-walled parts, and it is difficult to ensure thin-walled parts. The processing quality of thin-walled parts, and the existing tooling for thin-walled parts clamping adopts a rigid clamping method, which is easy to cause clamping deformation of thin-walled parts, which affects the dimensional accuracy and shape accuracy of thin-walled parts, thereby affecting thin-walled parts. The processing quality of the parts, at the same time, the existing tooling can only be used for the clamping of a single thin-walled part, which has a single function and is inconvenient to use
