Porous synchronous collecting and weighing device and method for attitude and orbit control engine product

Abstract

The invention discloses a multi-hole automatic synchronous collecting and weighing device and method for attitude and orbit control engine products. The multi-hole automatic synchronous collecting and weighing device comprises a cabinet body, a process system, a tool pressing mechanism, multiple sets of connecting rod devices, a rotary index plate, a lifting air cylinder and a weighing mechanism. The tool pressing mechanism, the rotary index plate, the lifting air cylinder and the weighing mechanism are installed on the cabinet body, and the process system is installed in the cabinet body. The tool pressing mechanism is mounted on a transverse mounting plate of the cabinet body through the Z-direction manual translation mechanism; the rotary index plate is mounted on an I-shaped mounting plate on the cabinet body, and the multiple sets of connecting rod devices are circumferentially and uniformly mounted on the upper end surface of the rotary index plate; a detachable collecting cup with two open ends is mounted at the upper end of the hollow shaft seat; the process system comprises a water tank and a plunger pump connected with an upper computer. The multi-hole automatic synchronous collection is realized by combining the collection pipe with the connecting rod device, and meanwhile, the accuracy and high efficiency of synchronous collection and collection results are ensured through automatic calculation and processing of multi-hole flow collection and weighing.

Description

technical field [0001] The invention belongs to the technical field of tiny flow measurement of aerospace engine products, relates to the synchronous collection and weighing of liquid flow, in particular to a multi-hole automatic synchronous collection and weighing device for attitude control engine products. Background technique [0002] Attitude and orbit control is a typical series of aerospace engine products. Its specific products include thrust chambers, heads, injectors, etc. The above products can be subdivided into different sub-series according to the difference in engine model. Among them, the porous collection and weighing device is mainly aimed at the head, thrust chamber and injector of the attitude and orbit control engine products. For the weighing part, this test is a necessary test item for this type of product. At present, the traditional process method for automatic simultaneous collection and weighing of porous is a timing weighing method that combines ...

Problems solved by technology

[0006] The above-mentioned test techniques generally have the following problems: the flow rate needs to be measured hole by hole during the whole test process, and each hole needs to be collected twice, and the overall test time is relatively long; because manual collection is used, the requirement for manual proficiency is high; due to manual Meter reading timing leads to large measurement errors, and it is necessary to increase the number of measurements to eliminate the impact of errors, which also increases the test time; lack of test platform, the goal of receiving all holes at the same time cannot be achieved; some jet water media accidentally hang on the wall when the initial process parameters are adjusted. The collection of test tubes will also lead to deviations in the final data results; and with the sharp increase in the batch production of finalized products, the overall test time is long, the measurement error is large, the test efficiency is low, and the manual physical strength is insufficient. The traditional method can no longer meet the product test needs.
