[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a plating hanger jig used for plating a flat work such as a printed board.

[0002]

2. Description of the Related Art As a plating hanger jig for plating a flat work such as a printed board, a large number of power supply clamps 2 holding an upper end of a work W on an upper frame 1 as shown in FIG. And a plurality of holders 4 for holding the lower end of the work W attached to the lower frame 3 have been widely used. However, with such a structure, there is no problem when the size of the work W is constant, but there is a problem that it cannot be used for works of different sizes.

Therefore, as shown in Japanese Utility Model Laid-Open Publication No. 63-71129, V-shaped hooks are formed in multiple stages inside two left and right vertical frames, and A plating hanger jig capable of adjusting a hanging height has also been proposed. This structure has the advantage that the height of the horizontal transfer frame can be adjusted according to the size of the work. However, this type of plating hanger jig usually deforms gradually during use, and the dimensional accuracy between the two left and right vertical frames is usually reduced. Gone or
On the contrary, there was a drawback that the horizontal frame was rattled.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and can be used for works of different sizes. The present invention has been completed to provide a plating hanger jig which can always stably hold the transfer horizontal frame.

[0005]

In order to solve the above-mentioned problems, the present invention has an upper frame having a plurality of power supply clamps, and a multi-stage hook hanging from both sides of the upper frame. Left and right vertical frames, and a plurality of work holders, and a changeover horizontal frame having a latching piece that is engaged at both ends with the latches of the vertical frame. The present invention is characterized in that the engaging piece is provided with a flange for preventing movement in the lateral direction, and the other engaging piece is provided without a flange for allowing movement in the lateral direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. 1 and 2 show the entire structure of the plating hanger jig of the present invention. Reference numeral 1 denotes an upper frame provided with a number of power supply clamps 2 for holding the upper end of a flat work W; Reference numerals 5 and 6 denote left and right vertical frames hanging from both sides of the upper frame 1. These left and right vertical frames 5 and 6 are provided with multi-stage hooks 7 and 8. As shown in FIG. 2 and FIG. 3, the hooks 7 and 8 are provided with V-shaped cuts in plates extending laterally from the vertical frames 5 and 6.

Reference numeral 9 denotes a changeover horizontal frame provided with a number of work holders 10 on the upper surface. The replacement horizontal frame 9 has locking pieces 11, 12 which are engaged at both ends with the locking members 7, 8 of the vertical frames 5, 6.
The vertical frames 5 and 6 are held by hooks 7 and 8 having appropriate heights according to the size of the work W. In the present invention, one of the latching pieces 11 of the replacement horizontal frame 9 is provided with a flange 13 for preventing the lateral movement, and the other retaining piece 12 is provided with no flange for allowing the lateral movement. There is as.

That is, as shown in FIG. 4 (a), one latching piece 11 of the replacement horizontal frame 9 has flanges 13 on both sides in the longitudinal direction.
As shown in FIG. 4 (b), the portion sandwiched between the flanges 13 was cut into a V-shape when viewed from the end face direction, and was cut into an inverted V-shape when viewed from the longitudinal direction. The recess 14 is provided. On the other hand, as shown in FIG. 5, the other hooking piece 12 of the replacement horizontal frame 9 is obtained by simply shaving the end into a V-shape when viewed from the end face direction. When engaged with the hook 7, it cannot be moved in the horizontal direction (the longitudinal direction of the transfer horizontal frame 9), but when the hook piece 12 is engaged with the hook 8 of the vertical frame 6, You can slide to.

The horizontal frame 9 is made of, for example, a stainless steel square pipe with resin lining. However, if the hooking pieces 11 and 12 are made of metal, the plating will adhere to them.
It is preferable to use an electrically insulating material such as plastic. Similarly, it is preferable that the hooks 7, 8 of the vertical frames 5, 6 are also formed of an electrical insulator.

[0010]

The plating hanger jig of the present invention having the above-described structure is used for plating a flat work W such as a printed board as shown in FIGS. The upper end of the work W is clamped by the power supply clamp 2 to energize, and the lower end of the work W is held by the work holding tool 10 of the transfer horizontal frame 9 to perform the plating while preventing the work W from warping.

The height of the horizontal transfer frame 9 is adjusted in accordance with the size of the work W. One of the latching pieces 11 of the horizontal transfer frame 9 has a flange 13 for preventing movement in the horizontal direction. By engaging the hooking piece 11 with the hook 7 of the vertical frame 5, the replacement horizontal frame 9 is supported without rattling. Also, since the other latching piece 12 has no flange that allows the lateral movement, even if the dimensional accuracy between the left and right vertical frames 5 and 6 is reduced due to deformation during use, the latching piece 12 can be hooked without any trouble. The stop piece 12 can be engaged with the hook 8 of the vertical frame 6. Since the work W is stably held at the upper and lower ends in this manner, it is possible to prevent the work W from falling during transportation.

[0012]

[Effects of the Invention] As described above, the plating hanger jig of the present invention can be used for workpieces of different sizes. Even if the dimensions between the frames change,
The changeover horizontal frame can always be stably held without play. Therefore, the present invention has an extremely large practical value as a plating hanger jig which has solved the conventional problems.
