It is held by the carrier frame (electrolytic frame) 5 and is immersed between the electrodes 2 (, 2) in the electrolytic treatment liquid Q.

成されている。A typical holding jig 10 is shown in FIG.
As shown in FIG. 4, the main body 11, the sandwiching piece 21, the sandwiching spring 39, and the sandwiching release operation lever 31 forming the sandwiching release means are configured.

14R). At least the holding portion 12 is made of a conductive material. The sandwiching piece 21 having the sandwiching claw portion 22 on the eccentric outer peripheral surface is rotatable about the support shaft 16 planted in the upright portion 13, and in a normal state, the sandwiching spring 39.
The work can be clamped by the urging force of.

By applying a forced external force in the direction of the arrow in FIG. 10, the drive portion 33 (connecting pin 34) can be moved in the guide groove 14 in the direction indicated by the chain double-dashed line. This connecting pin 3
A holding spring 39 is stretched between the shaft 4 and the support shaft 17, and a driven link 35 is provided between the holding spring 39 and the connecting pin 23 of the holding piece 21.

The gripping claw portion 22 rotates away from the center and separates from the gripping portion 12. In this released state, the work 6 is inserted while adjusting the position in use that allows the work 6 to be easily and reliably gripped and held depending on the direction of the work 6, that is, the form of the work 6, formed by the holding portion 12 and the holding piece 21.

し,製品のコスト高を招いている。By the way, in such a conventional structure, the work 6 is removed and the transport frame 5 (114R) is removed.
After being removed from the box, it is collected in a box or the like, but this posture when not in use is laterally laid down because the jig itself is in an unstable form, and at most, the horizontal direction can be aligned in FIG. Therefore, in the case of reuse, it is necessary to manually adjust the posture at the time of use for the new work 6, so that the work is complicated and enormous labor and time are required. Further, due to the difference between the non-use posture and the use posture, it is not possible to automate the clamping / releasing, the production efficiency is lowered, and the product cost is increased.

る。Thus, various automations of pinching and releasing have been studied and tried. For example, a hooking method in which a notch is processed in the work 6 and a hook-shaped jig is hooked therein, a driving method in which a wedge-shaped jig is forcibly driven into the work 6, and the work 6 is directly or indirectly laser welded to the transfer frame 5. And the welding method. However, in any of the methods, there is a risk that the workpiece 6 may drop during transportation, and thus instability in reliable holding of the work 6 remains, which not only increases the size and cost of the apparatus but also damages the work 6 itself. There are drawbacks in construction, maintenance and operation, such as waste of material and narrow applicability to the form of the work 6. Therefore, it is the actual situation that it is put to practical use in a limited case such as small-lot mass production.

I am convinced that the work of attaching and detaching the work 6 can be greatly simplified or eliminated, and as a result, the production cost can be greatly reduced.
