[Problems to be solved by the device]

 When forming the frame body by connecting the ends of the frame material arranged on at least three sides and the ends of the corner material interposed between the ends of each frame material with the work rivet, form the frame body directly below the molding tool. The work rivet at one corner of the framework is positioned, the rivet head is molded on the work rivet, and the work rivet of the next corner is positioned immediately below the molding tool. At the same time, there was a problem that the operating rate of the riveting machine decreased.

Therefore, an object of the present invention is to provide a riveting machine capable of simultaneously forming a rivet head on a work rivet at each corner.

[Action]

 A work rivet is inserted and fixed on the table using a jig.

Next, the left-side moving body and the right-side moving body are aligned so that the axes of the work rivets located on both corners of the front edge of the workpiece and the spindles of the left-side moving body and the right-side moving body are aligned with each other. Position control (that is, by XY axis control), and the axis of the work rivet located at both corners of the trailing edge of the workpiece and the axis of the spindle of the rear left moving body and the rear right moving body. The rear left moving body and the rear right moving body are positioned and controlled so that and match.

Thereafter, while lowering the spindle, the molding shaft is pressed against the upper end of the work rivet and the rivet head is molded by swinging and swinging the molding shaft.

A rivet head may be formed on a work rivet in the middle of the periphery of the workpiece.

Further, the left moving body, the right moving body, the rear left moving body, and the rear right moving body are moved and adjusted in the Z direction according to the height of the work rivet.

【Example】

 An embodiment according to the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a left-side moving body that moves in the XY plane and in the Z direction is located on both outer sides of the supporting table 1 for supporting the workpiece A into which the work rivet a has been inserted. 2 and a right side moving body 3 are provided.

Further, on the left and right behind the rear edge of the table 1, there are provided a rear left moving body 4 and a rear right moving body 5 which move in the Z direction in the XY plane.

As a method of transferring the left-side moving body 2, the right-side moving body 3, the rear-side left moving body 4, and the rear-side right moving body 5 in the X-axis direction, the Y-axis direction, and the Z-axis direction, from FIG. As shown in FIG. 6, a horizontal first ball screw 8 which is supported by a seat 6 and which is driven by reversible operation of a first motor 7 and a first ball screw 8 which is screwed into the first ball screw 8 are mounted on the seat 6 so that the table 1 can be mounted on the seat 6. The nut 10 fixed to the lower surface of the lower slide body 9 that slides in the direction toward and away from the edge and the bearing of the surface of the lower slide body 9 so as to intersect the first ball screw 8 at a right angle and the second motor. The horizontal horizontal second ball screw 12 driven by reversible operation 11 and the upper ball slide 12 which is screwed into the second ball screw 12 and slides along the edge of the table 1 on the surface of the lower slide 9. Was The nut 14 and the surface of the upper slide body 13 are supported, and the vertical third ball screw 16 driven by the reversible operation of the third motor 15 and the third ball screw 16 are screwed into the upper slide body 13 and the upper and lower surfaces of the upper slide body 13 are moved up and down. And a nut 18 fixed to an elevating body 17 that slides in the direction.

Further, a spindle 20 that is rotated by a motor 19 and is moved up and down by an appropriate method is provided on the surface of each elevating body 17, and a rivet head forming tool 22 that holds a forming shaft 21 at the lower end of the spindle 20. Is provided.

As shown in FIG. 7, the method of raising and lowering the spindle 20 includes supporting the cylinder 23 on the raising and lowering body 17 and, by the action of the cylinder 23, raising and lowering the piston shaft 24 integrally with the piston shaft 24. The spindle 20 is pierced through the core and supported.

With the above configuration, the work A is supplied onto the table 1 and is fixed by using a jig.

As shown in FIG. 8, the work piece A has a frame member 31 on three sides, a corner member 32 interposed between the ends of the frame member 31, and an end of the parallel frame member 31. It is composed of an interposing frame member 31 and a work rivet a previously inserted into each connecting portion.

After that, the computer operates the first motor 7 and the second motor 11 so that the axis of the predetermined work rivet a and the axis of the molding shaft 21 of the left-side moving body 2 and the right-side moving body 3 are aligned with each other. When a command is given, the drive of the first ball screw 8 moves the lower slide body 9 in the left-right direction, and the drive of the second ball screw 12 moves the upper slide body 13 in the front-rear direction (in the X-axis and Y-axis directions). Position control.

Further, the first motor 7 and the second motor 7 are set by the computer so that the shaft center of the predetermined work rivet a and the shaft center of the molding shaft 21 of the rear left moving bodies 4 and 3 and the rear right moving body 5 are aligned with each other. When an operation command is given to the motor 11, the lower slide body 9 moves in the front-rear direction by the drive of the first ball screw 8 and the upper slide body 13 moves in the left-right direction by the drive of the second ball screw 12 (X axis-Y axis). Direction) to perform positioning control.

After that, while the spindle 20 is lowered together with the piston shaft 24 by the action of the cylinder 23, the molding shaft 21 is pressed against the upper end of the work rivet a, and the spindle 20 and the molding tool 22 rotate to perform molding. By pivoting and swinging the shaft 21, a rivet head a'is molded as shown in FIG.

When changing the position of the molding tool 22 according to the height (length) of the work rivet a, the third ball screw 16 is driven by the operation of the third motor 15 to move the elevating body 17 up and down.

In the figure, 25 is a slide guide member for the lower slide body 9, the upper slide body 13, and the lifting body 17, 26 is an expansion joint, and 27 is a balancing cylinder.

【effect】

 As described above, according to the riveting machine of the present invention, it is possible to mold the rivet head, for example, on the work rivet at each corner portion of the framework by using one riveting machine.

Therefore, work efficiency can be significantly improved.

Since the spindle can be moved together with the forming tool in the Z direction, the position of the forming tool can be changed according to the height of the work rivet.
