A support device for eccentric thin-walled cylinder

Abstract

The invention discloses a supporting device for an eccentric thin-walled cylinder part. The supporting device comprises a self-adaptive universal joint, a telescopic screw rod, a base, a replaceable supporting block, a rotary handle, lock screws and rubber pads. One end of the telescopic screw rod is in threaded connection with an internal thread of the base. The length of the whole supporting device can be adjusted by rotating the rotary handle. The other end of the telescopic screw rod is adjustably connected to a universal joint body to form an angle-adjustable self-adaptive joint. The supporting block is fixed to the base through the lock screws. The rubber pads are pasted to the supporting block and the self-adaptive universal joint correspondingly. The supporting device is reasonable in structural design and convenient to use. The supporting block can be replaced according to eccentric parts of different sizes and shapes. The problems that eccentric thin-walled cylinder parts are hard to support, uneven in stress and rough in machined surface due to eccentric structures in the turning and milling process are solved well.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to a support device for a large eccentric thin-walled cylinder during turning and milling. Background technique [0002] At present, complex structures, large eccentric thin-walled cylindrical parts widely exist in the field of aerospace. Due to the complex structure, thin wall of the cylinder, and eccentric structure of such parts, it is difficult to effectively support and clamp during turning, milling and other processing processes, resulting in problems such as uneven force and poor surface quality during part processing. At present, in the turning process, technical means such as reducing the spindle speed, reducing the feed rate of the turning tool, and layered processing are usually used. Although the quality of the processed surface can be improved to a certain extent, the processing efficiency is low, and it cannot meet the high precision requirements of aeros...
