9A is an enlarged view of the portion B shown in FIG.
9B is a side view of FIG. 9A.

As shown in FIG. 3, the nut insertion portion 112 is provided with an inclination, and a J-shaped guide 112a and a triangular plate 112b are provided. The nut input portion 112 and the triangular plate 112b prevent the two nuts from entering the supply port 112h at the same time. Further, due to the inclination of the triangular plate 112b, the flanged nut flows following the J-shaped guide 112a, so that the flanged nut smoothly enters the supply port 112h in any posture.

As shown in FIG. 4, one side wall of the supply port 112h is provided with an R shape and a groove for tilting the flanged nut, and the other side wall is provided with an inclination. As a result, the nut with a collar that has flowed on the upper side of the horizontal collar can be turned vertically without being caught.

Further, the distance L1 between the side walls of the supply port 112h is slightly shorter than the flange diameter L2 of the flanged nut. As a result, the nut with a collar that has flowed on the upper side of the horizontal collar can be turned vertically without being caught.

As shown in FIG. 5, a fan-shaped movable presser plate 118 is provided at the outlet of the flanged nut. As a result, the nut with a flange is suppressed from rising, and by hitting the tilt correction guide 117, the posture of the nut with a flange is stabilized.

As shown in FIGS. 6 and 7, an inclination correction guide 117, an outward tilting plate 116 having a vertical stabilizer shape, and a triangular inclined plate 115 are provided at the outlet of the flanged nut. The tilt correction guide 117, the outward tilting plate, and the triangular tilt plate allow the flange side of the flanged nut to face downward.

As shown in FIG. 8, a central rectifying guide 113 having a substantially triangular shape and side rectifying guides 114 are provided on both sides thereof. As a result, even if the same direction on the flange side of the flanged nut continues, the same number of nuts can be supplied to the left and right supply positions 111p for the next time.

As shown in FIGS. 9A and 9B, the positioning bolt 1191 is provided substantially perpendicular to the flow direction of the flanged nut. As a result, the side surface portion of the arc of the nut with a flange is received so as to be sandwiched between points, so that the nut with a flange does not bounce and the position can be easily determined.

Further, the positioning magnet 1192 is provided by driving the flange portion substantially perpendicular to the positioning bolt 1191 so that the flange portion does not hang on the center of the magnet. As a result, it is possible to prevent the nut with a flange from rising and the position shift at the supply position 111p.

The details of the nut tightening portion 12 will be described.
FIG. 10 is a schematic diagram illustrating the socket according to the first embodiment.
FIG. 11 is a schematic diagram illustrating the socket according to the first embodiment.
FIG. 12 is a schematic diagram illustrating the socket according to the first embodiment.
FIG. 13 is a schematic diagram illustrating the socket according to the first embodiment.
FIG. 14 is a schematic diagram illustrating the socket according to the first embodiment.
FIG. 15 is a schematic diagram illustrating the socket according to the first embodiment.
FIG. 16 is a perspective view illustrating the flanged nut temporary tightening jig according to the first embodiment.

As shown in FIG. 10, the shape of the first socket 123 and the second socket 124 of the nut tightening portion 12 is a cylindrical shape having a tapered shape at the inlet, and the inner diameter thereof is from the hexagonal circumscribed circle of the nut with a flange. Make it a little bigger. Since the inner diameter of the socket is larger than the circumscribed circle of the flanged nut due to the tapered shape at the inlet, the flanged nut can easily enter the socket.

Further, a plurality of tapered pins 125 having a tapered tip are provided so as to protrude inward from the inner diameter of the socket. As a result, the hexagonal portion of the flanged nut can be hooked and rotated by the taper pin 125. The first socket 123 and the second socket 124 may be collectively referred to as a socket.

As shown in FIG. 11, the two magnets 126 are provided at positions where the center position is outside the circumscribed circle with respect to the hexagonal portion of the flanged nut and does not overlap with the taper pin 125. As a result, the nut with a flange is magnetized in the center of the socket, so that it can be easily hooked on the screw and can be temporarily tightened with a light force.

As shown in FIG. 12, the two magnets 126 are provided in the socket with different poles. This makes it possible to prevent the subsequent flanged nut from being magnetized when the nut tightening portion 12 is taken out.

As shown in FIG. 13, the mounting hole 126h of the magnet 126 is opened from the upper surface of the socket downward to the end surface so as not to penetrate the socket itself. As a result, it is possible to prevent the magnet 126 from being lost due to the magnet 126 coming out of the socket and foreign matter from adhering to the work (product).

As shown in FIG. 14, a non-magnetic collar 127 having a round shape or a tapered shape and also having a height adjustment is installed at the tip of a rotating shaft such as the first shaft M1 and the second shaft M2. As a result, the nut with a flange can be magnetized at the center of the socket in a stable state as a guide without affecting the magnetic field of the magnet.

As shown in FIG. 15, the allowance between the taper pin 125 and the rotating shaft is set so that the magnetic force is also cut off when the temporary tightening is completed and the socket is idle. As a result, the magnetic force is turned off when the temporary tightening of the flanged nut is completed, so that the nut tightening portion 12 can be removed from the flanged nut with a light force, and the temporary tightening amount can also be adjusted.

Further, the first axis M1 and the second axis M2 of the nut tightening portion 12 are installed not vertically but slightly diagonally in consideration of the load due to the gears. As a result, the first axis M1 and the second axis M2 become vertical due to the load of the gear, and the screw and the thread of the flanged nut can be engaged with each other.

As shown in FIG. 16, a tapered hole 113h is provided in the central rectifying guide 113 of the nut supply unit 11. Further, a Y-shaped guide 1193y is provided on the support plate 1193 of the nut supply unit 11. As a result, when the tip of the central pin 129 is inserted into the tapered hole 113h, the convex portion 128 moves along the Y-shaped guide 1193y. Then, the nut with a flange is set in the nut tightening portion 12 simply by inserting the tip of the center pin 129 into the tapered hole 113h and letting go.

Next, a method of using the flanged nut temporary tightening jig 10 will be described.
FIG. 17 is a perspective view illustrating the flanged nut temporary tightening jig according to the first embodiment.
FIG. 18 is a perspective view illustrating the nut tightening portion according to the first embodiment.

As shown in FIG. 16, the nut with a flange is supplied from the supply port 112h. The flanged nut flows to the supply position 111p between the central rectifying guide 113 and the side rectifying guide 114 via the tilt correction guide 117, the triangular inclined plate 115, the outward tilting plate 116, and the like.

Next, as shown in FIG. 17, the nut tightening portion 12 is lifted up and the nut tightening portion 12 is taken out. At this time, a nut with a flange is supplied to each of the first socket 123 and the second socket 124. By taking out the nut tightening portion 12, the nut with a flange for the next time flows to the supply position 111p.

Next, as shown in FIG. 18, the nut tightening portion 12 is set on the work (product), the main gear 12 m is turned in the target direction, and the flanged nut is temporarily tightened on the work. At this time, the flanged nut supplied to the first socket 123 and the flanged nut supplied to the second socket 124 are temporarily tightened at the same time.

After that, the nut tightening portion 12 is separated from the work, and the nut tightening portion 12 is returned to the nut supply portion 11.

In this way, according to the present invention, the supplied nut with a flange can be supplied to the supply position with the collar always facing downward, and can be temporarily tightened. As a result, it is possible to provide a temporary tightening jig capable of temporarily tightening a plurality of flanged nuts at the same time.
