Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in figures 1 and 2, the nut inner hole mistake proofing device comprises a mandril sliding block 1, a supporting sliding block 3, a lower cover plate I4, an L-shaped sheet 5, a microswitch 6, a lower cover plate II 7 and a mandril 8. The folding angle of the L-shaped piece 5 is fixed between the lower cover plate I4 and the lower cover plate II 7 through the ejector rod 8, one end of the L-shaped piece 5 penetrates through the lower cover plate I4, and the other end of the L-shaped piece 5 penetrates through the lower cover plate II 7. The ejector rod sliding block 1 is sleeved on one end of the L-shaped piece 5 and penetrates through the lower cover plate I4, and a spring is arranged between the ejector rod sliding block 1 and the L-shaped piece 5. One side of the L-shaped piece 5, which protrudes out of the lower cover plate II 7, is provided with a microswitch 6. One side of the L-shaped sheet 5 close to the microswitch 6 is provided with a conical bulge. Support smooth 3 and run through apron I4 down, and support smooth 3 one end that emits apron I4 down and pass through connecting piece 2 and ejector pin slider 1 fixed connection fast soon. The connecting piece 2 is made of copper sheets.
The utility model discloses a use: as shown in figure 3, when a nut with an M5 inner diameter and a nut with an M6 inner diameter exist in the mixed material, the L-shaped sheet 5 is selected to be an L-shaped sheet with one end corresponding to the M5 hole diameter, and the end penetrates through the lower cover plate I4 as above. When the nut 9 with the inner diameter of M5 falls, the nut 9 is sleeved on the L-shaped sheet 5. At the moment, the ejector rod slide block 1 is overstocked by the nut 9, and the L-shaped sheet 5 is also overstocked correspondingly through the spring. The L-shaped sheet 5 rotates around the ejector rod 8 at the folding angle, and the other end of the L-shaped sheet 5 triggers the micro switch 6.
As shown in fig. 4 and 5, will the utility model discloses use with the cooperation of pneumatic press, when the nut of M5 internal diameter whereabouts, after triggering micro-gap switch, the normal close becomes normally open, presses the pneumatic press button, and pneumatic press functions. The microswitch is not triggered, the circuit is normally closed, and the pneumatic press cannot operate when a button of the pneumatic press is pressed. When the nut with the M6 inner diameter falls down, the micro switch is not triggered and is still normally opened, the circuit is connected, the button of the pneumatic press is pressed, and the pneumatic press operates. And triggering the microswitch, normally opening the microswitch to be normally closed, disconnecting the circuit, and pressing a button of the pneumatic press to stop the operation of the pneumatic press.
When a nut with an M5 inner diameter is to be riveted, the nut is placed according to a link circuit shown in figure 4, the nut is pressed down by a button of a pneumatic press, the operation of the press is the nut with the M5 inner diameter, and if the pneumatic press does not operate, the nut with the M6 inner diameter is illustrated; when riveting a nut with an M6 inner diameter, according to a link circuit shown in figure 5, the nut is placed and the button of the pneumatic press is pressed, the press is operated by the nut with the M6 inner diameter, and if the pneumatic press is not operated, the nut with the M5 inner diameter is illustrated.
