Detailed Description
Examples
The embodiment provides an automatic switching device for a pressing head and a riveting head, which has the structure shown in fig. 1 and 2 and comprises a fixed connection mechanism, a power sliding mechanism and a crimping mechanism.
The fixed connection mechanism consists of a first fixed plate 1, a second fixed plate 3, a third fixed plate 4, a fourth fixed plate 5, a connecting flange 8 and a press-fit stress cylinder 9. The third fixing plate is placed along the horizontal direction of the whole device, the second fixing plate to the fourth fixing plate are mutually fixed through bolt connection and then are vertically arranged above the third fixing plate to form an opening groove which is U-shaped, the connecting flange is placed in the opening groove, the connecting flange is connected with the third fixing plate below through bolts, and the press-fit stress cylinder is fixedly arranged on the connecting flange through bolts.
The power sliding mechanism consists of a cylinder 2, a cylinder connecting piece 6, a first oblique cutting block 7 and a second oblique cutting block 11. The cylinder is fixed on the first fixed plate through a bolt, one end of the cylinder connecting piece is screwed on the cylinder piston rod through a threaded structure, the protruding portion of the other end of the cylinder connecting piece is matched with the groove portion of the first inclined cutting block, the first inclined cutting block is integrally placed in the hollow groove in the horizontal direction of the connecting flange, and the second inclined cutting block is placed in the center hole of the connecting flange.
The crimping mechanism consists of a connecting round pin 12, a pressing head 10 and a rivet 13. The rivet is fixed on the third fixed plate through a bolt, the pressure head is placed in a rivet center hole, the connecting round pin penetrates through the through hole in the horizontal direction of the pressure head, the pressure head can slide up and down in the rivet, and the sliding range is the center distance of waist-shaped holes on two sides of the rivet.
The working principle of the embodiment is as follows: when the mechanism is not contacted with a product, the pressure head can slide downwards due to gravity until the connecting round pin is contacted with the lower edge of the upper waist-shaped hole of the rivet, and at the moment, a part of the pressure head can extend out of the rivet. When the product is required to be pressed, the air cylinder drives the first inclined cutting block to move horizontally and advance, the first inclined cutting block can apply downward force to the second inclined cutting block in the moving process, so that the second inclined cutting block moves downwards and is propped against the upper plane of the pressing head, and when the pressing head is contacted with the product, no gap exists among the first inclined cutting block, the second inclined cutting block and the pressing head, and the pressing head cannot retract into the rivet after being stressed. When the product needs to be riveted, the cylinder drives the first oblique cutting block to move horizontally and retract, gaps appear among the first oblique cutting block, the second oblique cutting block and the pressure head, in the whole riveting process, the pressure head is firstly contacted with the product, the pressure head is retracted into the rivet head after being stressed, then the rivet head is contacted with the product, and at the moment, the riveting of the product is started.
