Adaptive adjustment device used for large-area protection

Abstract

The invention provides an adaptive adjustment device used for large-area protection. The adaptive adjustment device used for large-area protection comprises a protection cover, a left hinge support, aright hinge support, a lower hinge support, a left spring seat body, a right spring seat body, a left sliding plate, a right sliding plate and a water pan. The protection cover comprises a roller boxand a roller blind connected into the roller box. A rotary shaft penetrating through the roller box is arranged in the middle of the roller box. A protection cover clamping plate is connected to thebottom of the roller blind. The left sliding plate and the right sliding plate are connected with a power device and are connected with a spinning roller base of a spinning machine. When the spinningmachine adjusts a staggering technological parameter, the left sliding plate and the right sliding plate move up and down; and under the effect of a mechanism, the protection posture of the adaptive adjustment device can be adaptively changed at any time, so that spinning under different staggering quantities is ensured while large-area protection of equipment is flexibly, stably and effectively achieved, the labor intensity is relieved, and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of large-scale heavy-duty machinery, in particular to an adaptive adjustment device for large-area protection. Background technique [0002] The large-scale vertical spinning machine is the key equipment developed to meet the processing needs of my country's aerospace and other major fields. This equipment can realize the spinning of aerospace engine shells, large aero-engine casing parts, and large pressure vessels. The processing has filled the strategic gap in my country's large-scale CNC powerful spinning machine, reached the international advanced level, and provided strong technical support for my country's military industry. [0003] The equipment is a vertical overall frame structure with an overall weight of about 500 tons. The maximum diameter of the machined parts is 2600mm, and the spinning thrust can reach 1000kN. Control within the allowable range to ensure the manufacturing, assembly and proce...

Moreover, according to the process requirements, staggered spinning is required to improve the efficiency and quality of spinning. At present, the maximum height difference of the longitudinal sliding plate varies from 15 to 60 mm, which increases the difficulty of large-area protection, especially for different process parameters. The automatic adjustment of the stagger distance has higher requirements, not only to ensure the running stability of the longitudinal slide plate and the protective cover itself, but also to effectively ensure the reliability of the protection, and not exceed the deflection tolerance of the rotary axis of the protective cover itself

[0004] Whether it is horizontal or vertical spinning equipment, staggered spinning is usually achieved by replacing the staggered pad. Every time the staggered process parameters are changed, the spinning wheel must be disassembled and a staggered pad of appropriate thickness must be replaced to ensure spinning. The rationality of the parameters, this method increases the frequency of tooling replacement, especially for the development of trial products, which greatly restricts the production efficiency, and increases the production cost and the labor intensity of the operator
