[0020] Working principle: In the present invention, the torsion spring is pre-placed on the discharge plate, and the downlight is placed inside the positioning fixture. The torsion spring needs to be installed between the two cross bars on the downlight, and the mechanism starts to work. First, the displacement cylinder works, and the output end drives the bracket and the overall mechanism to move toward the discharge plate. When the cross frame is driven to move to the top of the discharge plate, the expansion cylinder works to drive the claw to drive the claw to slide on the straight block, so that the claw expands and then merges. The claw clamps the torsion spring on the discharge plate, and at the same time, the downward pressing paddle clamps one end of the torsion spring. The displacement cylinder drives the bracket to return to its position and move in the direction of the seat plate to the top of the positioning fixture and the downlight. The lifting cylinder works to drive the straight plate to move downward, and the straight plate drives the structure on its surface to move downward, so that the end of the torsion spring controlled by the downward pressing paddle corresponds to the position on the downlight that needs to be installed. , the right push-pull cylinder and the left push-pull cylinder start to work, the output ends of the right push-pull cylinder and the left push-pull cylinder push the connecting block to move in relative directions, and the connecting block drives the right lower pressure cylinder and the left lower pressure cylinder to move in the up and down directions of the X-axis, and drives the turning plate to move at the same time, the turning plate drives the lower pressure paddle to squeeze the elastic end of the torsion spring, and deformation occurs. At this time, the right lower pressure cylinder and the left lower pressure cylinder simultaneously drive the turning plate to move downward, so that the deformed torsion spring enters the cross bar where the downlight needs to be installed, and then the two push-pull cylinders return to their positions, and the torsion spring resets to the cross bar due to its own elastic reset, the expansion cylinder expands outward, driving the claw to loosen the other end of the torsion spring, and this end of the torsion spring falls due to gravity, the claw expands and completes the reset, the two lower pressure cylinders also drive the turning plate to return to their positions, and the lifting cylinder also returns to its position, and the above process is repeated to install the next torsion spring.
