In this embodiment, telescopic part is including locating the telescopic cylinder on the locating plate of impressing, be equipped with telescopic link 8 on telescopic cylinder's the catch bar.

In this embodiment, the height of the inclined guide groove 6 is slightly higher than the thickness of the snap spring 5, so that the snap spring 5 cannot be overturned during pushing and compressing.

In the embodiment, the clamp spring charging barrel 2 is commonly adopted, clamp springs 5 to be installed are uniformly arranged and arranged, and are prevented from rotating within a certain angle; pushing out a bottommost snap spring 5 in the snap spring material cylinder 2 through the telescopic component; the clamp spring 5 is gradually compressed inwards through the inclined guide groove 6 when pushed out, and the height of the inclined guide groove 6 is slightly higher than the thickness of the clamp spring 5, so that the clamp spring 5 cannot turn over when pushed and compressed; the compression amount of the clamp spring 5 is accurately controlled through accurate servo positioning of the telescopic part; compressed clamp spring 5 enters into guide thrust block 3 and then is pushed down by moving pressing head 4 vertically above and sent into the clamp spring slot position of installation, and at the moment, clamp spring 5 automatically opens to realize the installation.

Specifically, the moving press-in head 4: the clamp spring 5 is fed downwards after entering the guide thrust block 3, and can be driven by an external cylinder or a motor to move up and down in specific implementation; a clamping spring charging barrel 2: the clamping springs 5 are used for vertically stacking various clamping springs 5 and can be pushed out through the clamping springs 5 at the bottommost part of the guide groove at the lower part; a telescopic component: the clamping spring pushing device is used for pushing out the clamping spring 5 at the lowest part of the clamping spring charging barrel 2, precisely pushing the clamping spring 5 into the guide thrust block 3, and realizing radial compression of the clamping spring 5 through telescopic stroke control; guide thrust block 3: the clamp spring 5 is used for first compression and guide, and the clamp spring 5 pushed in is compressed by the size change of the notch in the radial direction through the design of the inclined plane opening of the bottom surface; pressing in the positioning plate 1: be used for 5 secondary compression of jump ring and direction, be located under the thrust block 3 that leads, the design has cone circle guiding hole 7, and when jump ring 5 was pressed into by removal pressure head 4, through can 7 recompression jump rings 5 of cone circle guiding hole, get into cylinder installation guiding hole at last.
