The present invention relates to a riveting device, and more particularly to a riveting device of an improved structure for supplying the rivet in an inverted state.

Conventionally, the riveting direction of the riveting device is to fix the rivet vertically with the head facing the top side and the foot facing the bottom side. This structure could not satisfy all the different requirements.

The present invention has been devised in consideration of the foregoing facts. The main object of the present invention is to provide a riveting device for feeding the rivets in an inverted state with the head facing the bottom side and the foot facing the top side.

In order to achieve this and other objects of the present invention, the riveting device includes an upper riveting unit, a lower riveting unit, a material pickup device, and a rivet feeder.

The upper riveting unit is transversely coupled to the riveting power drive unit, the hollow vertical shaft connected to the riveting power drive unit, the movable riveting block fixed to the bottom side of the hollow vertical shaft, and the hollow vertical shaft. It includes a ring push rod. The hollow vertical shaft includes a longitudinal slot. The bottom riveting unit has a vertical position bar, a fixed riveting block fixed to the upper side of the vertical position bar and directed in a straight line toward the movable riveting block of the upper riveting unit, and an axial direction in the center of the fixed riveting block. And a movable pin movably mounted thereto. The material pick-up device comprises a return spring mounted on the hollow vertical shaft, a piston mounted on the hollow vertical shaft and supported by the return spring of the material pick-up device, and a hollow vertical shaft vertically and longitudinally from around the piston. A press rod extending outward, a pin fixedly connected to the center of the piston bottom side and extending out of the movable riveting block, a material pickup power drive unit, a pressure member connected to the power drive unit, and transverse to the pressure member It includes a push rod connected in the direction. The rivet feeder includes a return spring, a pivoted feeder arm supported by the return spring, a push rack attached to the feeder arm, and an adjustment screw to adjust the deflection angle of the feeder arm.

1 to 3, there is shown a riveting device according to the present invention that includes an upper riveting unit 10, a lower riveting unit 20, a material pickup device 30, and a rivet feeder 40. have.

The upper riveting unit 10 includes a riveting power drive unit 13, a hollow vertical shaft 12 connected to the riveting power drive unit, and a movable rivet fixed to the bottom side of the hollow vertical shaft 12. A casting block 11 and a push rod 14 which is laterally coupled to the outside of the hollow vertical shaft 12. The hollow vertical shaft 12 has a longitudinal slot 121 cut through the circumferential wall.

The bottom riveting unit 20 is fixed to the vertical position bar 22 and the upper side of the vertical position bar 22 and fixed to the movable riveting block 11 of the upper riveting unit 10 in a straight line. A riveting block 21 and a movable pin 23 movably mounted axially in the center of the fixed riveting block 21.

The material pick-up device 30 includes a return spring 32 mounted to the hollow vertical shaft 12, a piston 31 mounted to the hollow vertical shaft 12 and supported on the return spring 32. A press rod 33 extending vertically from the periphery of the piston 31 and outwards of the hollow vertical shaft through the longitudinal slot 121, and fixedly connected to the center of the bottom side of the piston 31; Pin 34 extending outside the centering block 11 (center hole), the material pickup power drive unit 35, the pressure member 36 connected to the material pickup power drive unit 35, and the pressure member ( And a push rod 37 laterally connected to 36.

The rivet feeder 40 has a return spring 43, a feeder arm 41 having an upper side pivoted at a base (not shown) of the apparatus and supported by the return spring 43, and the feeder arm 41 And a deflection of the feeder arm 41 and the push rack 42 having a first push surface 421 and a second push surface 422 attached to the push rod 14 and the push rod 37 respectively. And adjusting screw 44 for adjusting the angle.

Referring to FIG. 4, the feeder arm 41 has a space between the riveting blocks 11 and 21 at predetermined time intervals, with the rivets 50 facing the bottom side and the feet facing the top side. In turn, the rivet 50 is supplied. After one rivet 50 reaches the riveting position between the movable riveting block 11 and the fixed riveting block 21, the pressing member 36 of the material pickup device 30 is lowered and the press rod ( Pressed on 33 presses piston 31 and pin 34 downward toward pin 23. At this time, the pin 34 is inserted through the rivet 50 at the front side of the feeder arm 41, and the push rod 37 is pressed against the second push surface 422 of the push rack 42 to feed the feeder. The arm 41 is moved away from the supply position, so that each rivet 50 is fixed to the pin 34 away from the leader arm 41 and pressed by gravity to fix the riveting block at the vertical position bar 22. Descend toward 21. Thereafter, the pressing member 36 is returned by the material pickup power drive 35, the piston 31 and the pin 34 are returned by the return spring 32, and the feeder arm 41 is returned by the return spring ( 43, the rivet 50 is released from the fixed riveting block 21.

With reference to FIG. 5, the riveting action is initiated after the workpiece is placed in the stationary riveting block 21 at the vertical position bar 22. At this time, the riveting power drive unit 13 is controlled to move the hollow vertical shaft 12 and the movable riveting block 11 downward with respect to the rivet 50 in the stationary riveting block 21, Thus the rivet 50 is riveted to the workpiece. During the downward stroke of the hollow vertical shaft 12, the push rod 14 is pressed against the first push surface 421 of the push rack 42 to move the feeder arm 41 from the patch. After the riveting action, the hollow vertical shaft 12 is returned by the riveting power drive 13, and the feeder arm 41 is returned by the return spring 43.

The prototype of the riveting device was configured to have the features of FIGS. Riveting works well, providing all the features discussed above.

Although specific embodiments of the present invention have been described in detail for purposes of illustration, various modifications and variations may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.

According to the present invention, there is provided a riveting device for supplying rivets with the head facing the bottom side and the foot facing the top side upside down, to satisfy all different requirements in the riveting operation.
