Problems solved by technology

[0002] At present, the fixtures and fixtures for the air flow test of aero-engine vortexers all adopt the method of thread spinning to clamp the test piece. When the device loads and unloads the test piece, the pressing piece needs to rotate 10-20 circles, which leads to the clamping efficiency of the device. Low; and the compression force varies from person to person, it is easy to cause the gasket and the test piece to rotate and shift, cause gas leakage and affect the test data, and at the same time, it is easy to cause the unsafe phenomenon of the test piece and fixture falling

Abstract

The invention discloses a swirler airflow test tool holddown gear comprising a tool mount body with a disc structure; the middle of the tool mount body is provided with a cavity used for mounting thetest tool; a seal pad is arranged in the cavity; the tool mount body is connected with a cylinder bearer through a plurality of poles; a cylinder is arranged on the cylinder bearer; a compact cavity is arranged between the plurality of poles, and arranged right above tool mount body cavity; a control circuit controlling the cylinder to open / close is provided, and comprises a compact switch controlling the cylinder to move downwards, and a first solenoid valve connected with the compact switch; the control circuit also comprises a loose switch used for controlling the cylinder to move upwards,and a second solenoid valve connected with the loose switch; the first and second solenoid valves are respectively connected with the air inlet of the cylinder through a cylinder current limiter; thedevice is reliable in sealing, can conveniently and fast clamp the test tool, and safe and reliable, thus preventing the experiment data inaccurate problems caused by gas leakage.

Description

technical field [0001] The invention belongs to the technical field of air flow test of an aero-engine vortex device and relates to a pressing device for a vortex device air flow test tool. Background technique [0002] At present, the fixtures and fixtures for the air flow test of aero-engine vortexers all use the thread spinning method to clamp the test piece. When the device loads and unloads the test piece, the pressing piece needs to rotate 10-20 times, which leads to the clamping efficiency of the device. Low; and the compression force varies from person to person, it is easy to cause the gasket and the test piece to rotate and shift, cause gas leakage and affect the test data, and it is easy to cause unsafe phenomena that the test piece and the fixture fall. Contents of the invention [0003] The invention provides a compacting device for a vortexer air flow test tool; the device is reliable in sealing, and is convenient, fast, safe and reliable for clamping the tes...
