Flat plate model ablation feeding device

Abstract

The invention provides a flat plate model ablation feeding device. The device comprises a flat plate model support, parallel clamping jaws and a pull rod type air cylinder, wherein the flat plate model support comprises a model fixing plate and a support fixing plate, the model fixing plate and the support fixing plate are rotationally connected through a support rotating shaft, and a rotating angle indicating element is arranged on the support rotating shaft. The device is advantaged in that a rotation angle of the model support can be rapidly and accurately set through the rotation angle indicating element, test debugging efficiency is improved, the flat plate model support and the pull rod type air cylinder in the device are rotationally connected through the parallel clamping jaw, and the end, away from the model fixing frame, of the pull rod type air cylinder is rotationally connected with the air cylinder fixing frame. According to the device, sequential actions of the pull rod type air cylinder and the parallel clamping jaw are controlled through the control air, two-stage adjustment of the rotation angle of the flat plate model support is achieved, problems that the rotation angle setting process of the flat plate model support is complex and the precision is low are solved, test debugging efficiency is improved, and the requirement of complex tests for multiple rotation angles is met.

Description

technical field [0001] The invention relates to the technical field of flat-plate model ablation, in particular to a flat-plate model ablation feeding device. Background technique [0002] In the aerospace field, the arc generated by the arc heater is used to ablate the model to complete the assessment of related materials. The plate model ablation test needs to fix the model on the support, and rotate with the model support at a certain angle to realize the adjustment of the ablation heat flow. [0003] The existing test uses a rod-type cylinder to push the model support to rotate, so only two rotation angles can be set, which cannot meet the needs of complex tests. At the same time, when setting the rotation angle, an angle ruler is used to perform multiple checks to realize the angle setting, and the operation process is complicated. , and the work efficiency is low. Contents of the invention [0004] The purpose of the present invention is to provide a flat model abl...
