Detailed ways

The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

Example

As shown in Fig. 1-Fig. 12, a circlip assembly mechanism includes a press-fit positioning plate 1, a telescopic part provided on the press-fit positioning plate 1, a spring barrel 2, a guide thrust block 3, and a moving Pressing the head 4, a plurality of circlips 5 are placed in the circlip material cylinder 2, the guide thrust block 3 is provided with a sloped guide groove 6, and the opening of the circlip 5 faces the sloped guide groove 6 , the telescopic component is used to push the bottommost circlip 5 in the circlip cartridge 2 into the guide thrust block 3, and compress the circlip 5 through the inclined surface guide groove 6 once, and the The movable press-in head 4 is arranged just above the guide thrust block 3 , and a tapered guide hole 7 is provided on the press-in positioning plate 1 just below the guide thrust block 3 . The movable press-in head 4 Move down to push the once-compressed circlip 5 into the tapered guide hole 7 for secondary compression, and continue to move downward to press the twice-compressed circlip 5 into the part installation straight hole middle.

In this embodiment, the telescopic component includes a telescopic cylinder disposed on the press-fit positioning plate, and a telescopic rod 8 is provided on the push rod of the telescopic cylinder.

In this embodiment, the height of the inclined surface guide groove 6 is slightly higher than the thickness of the retaining spring 5, so that the retaining spring 5 will not be turned over when it is pushed and compressed.

In this embodiment, the circlip material barrel 2 is generally used, and the circlip springs 5 to be installed are uniformly arranged and arranged to prevent it from rotating within a certain angle; the bottommost circlip 5 in the circlip material barrel 2 is pushed out through the telescopic component; When the circlip 5 is pushed out, it is gradually compressed inward through the inclined surface guide groove 6. The height of the inclined plane guide groove 6 is slightly higher than the thickness of the circlip 5, so that the circlip 5 will not turn over when it is pushed and compressed; The positioning realizes the precise control of the compression amount of the circlip 5; the compressed circlip 5 enters the guide thrust block 3 and is pressed down by the moving pressing head 4 vertically above into the installed circlip slot. The spring 5 opens automatically to realize the installation.

Specifically, move the press-in head 4: used for the circlip 5 to enter the guide thrust block 3, and then feed downward, and can be driven up and down by an external air cylinder or motor during specific implementation; circlip 2: used for A variety of circlips 5 are stacked vertically, and the bottommost circlip 5 can be pushed out through the lower guide groove; telescopic parts: used to push out the bottommost circlip 5 of the circlip cartridge 2, and push the circlip 5 precisely to the guide stop. In the push block 3, through the telescopic stroke control, the radial compression of the circlip 5 is realized; the guide thrust block 3: used for the first compression and guidance of the circlip 5, through the design of the slope opening on the bottom surface, the pushed The spring 5 is compressed radially by the change of the size of the notch; it is pressed into the positioning plate 1: it is used for the secondary compression and guidance of the circlip 5. When the moving press-in head 4 is pressed in, the retaining spring 5 is compressed again through the tapered guide hole 7, and finally enters the cylindrical installation guide hole.
