The utility model discloses ICT double stroke mechanism, including base, upper pressing plate and hook drive module, be used for installing in the processing mesa, be equipped with the lower mould on the base, the back surface rotation connection of lower mould is used for the upper fixed frame of mould closing, be equipped with in the inside of upper fixed frame, the inner surface of lower mould is equipped with the component for being detected, the utility model discloses when the electromagnet of hook drive module is electrified and drives, can accurate drive hook post along the guidance of concave frame and carry out telescopic motion, and hook post penetrates concave frame and forms the engagement with the hook seat, effectively avoids the looseness or deviation when mould closing, when the push plate of pneumatic cylinder drive module slides, the guide screw on the surface of upper reinforcing plate passes the limiting slot of movement push plate, the movement track of movement push plate is restricted, avoids the deflection in the movement, through double stroke design, only long needle contact PCBA and carry out test in the second stroke, avoided the interference produced by short needle as antenna, ensure the stability and accuracy of test signal.

The invention relates to a video monitoring automatic glancing method and system for an aero-engine test. The method comprises the following steps: determining a to-be-glanded position of an aero-engine; the number and the scanning range of automatic scanning equipment are determined according to the position to be scanned; planning a glancing path based on the automatic glancing equipment, and setting a glancing strategy on the glancing path; and associating the glancing strategy with a test run program, and carrying out glancing according to the test run program. The existing video monitoring process is optimized through an automatic means, and the problems of low efficiency, incomplete monitoring, insufficient operation standardization and the like caused by manual operation are solved. By pre-determining the to-be-glanded position of the aero-engine and planning the automatic glancing path and strategy based on the positions, the invention realizes the standardization of the monitoring work. Manual operation is replaced by automatic glancing, errors and omissions caused by human factors are reduced, and the reliability and comprehensiveness of monitoring are improved.
