It is characterized by having been established.

[Embodiment J of the Invention Next, an embodiment of the present invention will be described with reference to FIGS. 5 to 11.

Figure 5 shows a plate-shaped workpiece 2 using the Mevuki jig of the present invention.
FIG. 6 is a front view of a state in which six sheets are suspended, and FIG. 6 is a side view.

15 is a copper plate, which is a member corresponding to the copper plate 5 in FIG. 3 showing the prior art. A feeder 16 is fixed to both ends of this copper plate 150 with bolts 17.

7 is an arm block attached for transportation.

A clamp jig 11, which will be described later with reference to FIGS. 9 and 10, is attached to the copper plate 15 to suspend it.

Copper wires 12 provided with crimp terminals 13 are connected with screws 14 and 19 to ensure complete continuity at the mounting portion. 18
10 is a square pipe for reinforcement, and 10 is a Novkubin for positioning.

FIG. 7 is a side view of the above-described copper plate 15 in which the feeder 16 is attached and placed on the power receiving block 22 for conduction, and FIG. 8 is a front view of the same. 20 is a washer for the above-mentioned mounting bolt, and 21 is a correction plate for adjusting the engagement dimension.

In this embodiment, the feeder 16 is attached to the copper plate 15, which is a beam-like member of the electric conductor, as described above.

A clamping jig 11 for clamping a plate-shaped workpiece 2 is connected and fixed.

FIG. 9 is a side view of the clamp jig 11, and FIG. 10 is a front view thereof.

Reference numeral 31 denotes a clamp body, to the lower end of which a clamp plate 46, which is a locking member, is fixed with screws 42.

The clamp piece 44 is pivotally attached to the above-mentioned clamp body 31 at the pivot point using the pin 67. 38 is a split bottle for stopping the removal. At this clamp station 37, a clamp plate (hereinafter referred to as an operating clamp plate) 45, which is a movable member, is attached to the screw 43.
It is fixed.

The lever 39t-hi/41 is rotatably attached to the clamp piece 44 mentioned above. 38 is a split bottle.

Opening connection plate 3 between the clamp body 31 and the lever 39
3 and the pins 52 and 47 to form a 4-link mechanism. FIG. 11 is an explanatory diagram of the four-link mechanism.

The connecting plate 33 and the bottle 32 are fitted together through an elongated hole so that they can rotate and slide freely.

Since the 4-link mechanism is configured as described above, the lever 39 is rotated clockwise from the position shown by the solid line in the counter-arrow direction to the chain line 69' position with the clamp body 31 and stationary clamp plate 46 stationary. When the clamp piece 44 is rotated counterclockwise around the bottle 37,
The operation clamp plate 45 attached to this is shown by the chain line 4
5', it rotates in a direction away from the stationary clamp plate 46.

Further, along with the above rotation, the connecting plate 53 rotates counterclockwise around the dovetail 732.

Therefore, if a knife is applied to rotate the connecting plate 33 counterclockwise, each of the above-mentioned members will rotate as described above, and the operating clamp plate 45 will be opened.

In this embodiment, the release l/bar 25 is attached to the connecting plate 33 with a pin 40. As a result, when the vicinity of the upper end of the release lever 25 is pushed in the direction of arrow B, the operation clamp plate 45 is released in a counterclockwise direction about the bin 37.

Further, when the vicinity of the upper end of the lever 39 is pushed in the direction indicated by the arrow, the operation clamp plate 45 performs a clamping operation in a clockwise direction around the bottle 37.

The bottle 34 is fixed to the clamp body 51, and the lever 3 is
A spring 35 is interposed between the lever 39 and the lever 39 to force the lever 39 in the opening direction. As a result, when the operating clamp plate is in the open position as shown by the chain line position 45', it is held in that position, making it easier to clamp the plate-shaped workpiece 2. 36 is a stopper bin during opening operation.

Furthermore, when the lever 59 is fully pushed in the direction of the arrow A and the operating clamp plate is set to the solid line position 45, the three bins 41.4
7.32 are aligned almost on a straight line, so the posture can be maintained without applying a separate urging force). A long screw 27 and an elastic body 29 are provided as means for elastically restricting the sliding movement of the connecting plate 33 so that it can automatically adapt to changes in the thickness of the plate-shaped workpiece 2. The above long screw 27 is
It is inserted gently into a through hole made in a bracket 48 fixed to the clamp body 31, and the cylindrical elastic body 29 is brought into contact with the bracket 48 through the tabs 28, and the nuts 26 are inserted from both sides of the clamp body 31 as appropriate. I feel nervous. As a result, the long screw 27 is allowed to move slightly in the vertical direction and is supported elastically. Turn the nut 26 to adjust the long screw 27 up and down VC, and bring the lower end of the long screw 27 into contact with the tip of the connecting plate 33. As a result, even if the thickness of the plate-shaped workpiece 2 changes slightly, it can be firmly clamped between the two clamp plates 45 and 46. In this embodiment, a workpiece having a thickness of 15K-2.5m can be properly held.

When attempting to clamp a workpiece having a thickness of α5w1 or less or a workpiece having a thickness of 2.5g or more, the long screw 27 may be adjusted up or down by turning the nut 26.

Since one method of workpiece thickness can be tolerated over a wide range, it is possible not only to handle variations in manufacturing dimensions for workpieces of the same model, but also to hold all workpieces of different models. In practice, it is versatile enough to be used for all thicknesses of workpieces, except for extremely irregularly shaped objects.

The plating jig constructed as described above operates when the lever 69 is pushed in the direction of arrow A shown in FIG.
clamps and holds the plate-shaped workpiece 2, and has great adaptability to the thickness of the plate-shaped workpiece, and furthermore, when the release lever 25 is pushed in the direction of arrow B, the operation clamp plate 45 is clamped. Release and maintain the released position. In this way, it is possible to clamp and release the plate-shaped workpiece 2 by simply pressing the arrows A and B, and also to suspend the plate-shaped workpiece 2 that is being clamped. It is also convenient for transportation.These operating characteristics make it easy to automate the plating equipment by using a single plating jig.

12 to 16 show an embodiment different from the above-described embodiment, in which the shapes of the stationary clamp plate 46 and the moving clamp plate 46 in the previous embodiment are further improved.

FIG. 12 is a front view of the improved stationary clamp plate 46',
Figure 3 is also a side view. Stationary clamp plate 46 of this example
' has a two-pronged claw 46a formed in the gripping portion at its lower end;
