Description

[0001] APPARATUS FOR RIVETTING [0002]

The present invention relates to an automatic riveting apparatus for joining metal materials using rivets without using solder.

Generally, a riveting device is used for combining various devices and parts used in various fields. The riveting device generally includes a jig for fixing an object to be riveted (hereinafter referred to as a " material "), And a pressing device for pressing the rivet placed on the material while descending.

Accordingly, in the conventional riveting apparatus, a rivet for joining a material and a material to be worked by a worker on an upper part of the jig is placed and fixed, and then the rivet is pressed by a cylinder to press the rivet firmly. At this time, the pressure point (work position) adjustment of the riveting hammer is normally performed by a worker manually moving the jig through the naked eye and adjusting the position of the upper workpiece and the rivet to perform a work with a rivet hammer which is lifted and lowered.

Therefore, the conventional riveting operation by hand has remarkably reduced the accuracy and accuracy of the riveting operation, and the defect rate is high. Moreover, the process of inputting, working, and discharging one material is repeated in sequence, I had a problem.

Therefore, the above-described riveting apparatus of the present invention continuously performs repeatedly the steps of: (1) preparing a workpiece; (2) introducing a workpiece; (3) setting a position of a rivet pressing point; (4) riveting a workpiece; .

To explain this in more detail,

① Material preparation stage;

As shown in FIG. 2, the first and second transfer devices 1 and 2 constituted by the LM guide actuator 3 and the first and second supply plates 2 and 21 on the upper and the second transfer devices 11, A workpiece j is prepared for fixing the jig d suitable for the workpiece e to be worked on and then the workpiece e and the rivet are placed on the jig d. Where the jig d is usually bolted to the first and second supply plates 2 and 21 and the material e and the rivet are placed on top of the jig d.

② Material input phase;

When the upper material preparation step is completed, one of the first and second conveying devices 1 and 2 of the lower body a is operated as shown in FIG. 5, One of the plate 2 and the second supply plate 21 is advanced and conveyed to the pressure device (c).

For example, when the LM guide actuator 3 of the first forward / backward transfer device 1 is operated, the rotary motor 31 of the LM guide actuator 3 rotates the ball screw 32 to be screwed The first supply plate 2 connected to the nut block 35 is advanced while feeding the nut block 35 so that the workpiece e and the rivet of the upper jig d are positioned on the line of the pressurizing device c.

At this time, the second pre- and post-conveying device 11 maintains a stop state.

③ riveting pressure point position setting step;

The LM guide actuator 3 of the left and right conveying devices 4 constituting the upper body b is operated to move the left and right conveying devices 4 , The right transfer plate 41 is adjusted in the left and right directions so that the position of the pressing device c formed at the front is positioned so as to be in line with the position of the rivet placed in the material e.

The LM guide actuator 3 of the lifting and lowering device 5 configured on the front surface of the left and right transporting plate 41 is operated simultaneously with the conveyance of the left and right transporting plates 41, So that the rivet head 6 of the forward pressing apparatus c is positioned at a predetermined distance from the upper end of the rivet placed in the workpiece e.

For reference, the position of the material is set so that the first and second conveying devices 1 and 11 set the Z axis, the left and right conveying device 4 sets the X axis setting, So that the rivet head 6 is accurately positioned at the upper end of the rivet.

④ riveting step;

When the rivet head 6 of the pressurizing device c is set at a predetermined position through the above step, the pressurizing motor 62 installed at the upper end of the lifting plate 51 presses the rivet hammer 6 in the material e The rivet is pressed to the top of the rivet.

When a large number of rivets are placed on the upper material (e), the upper transferring process (1), the left transferring device (4), and the lowering device (5) Take the pressure point and perform riveting.

⑤ Material release stage;

When the rivetting is completed through the above step, the initially operated first and second conveying devices 1 are returned to the original state by moving the upper first supply plate 2 backward to discharge the material e from the upper jig d .

When the first feeding plate 1 returns to the home position, the second feeding device 11, which was in the standby state, is operated simultaneously, and the upper second feeding plate 21 is fed on the feeding line of the pressing device c Forward feed ① material preparation step ② material input step ③ rivet pressing point positioning step ④ riveting step ⑤ material discharge step repeatedly.
