PURPOSE:To obtain the title work holding frame capable of surely holding a work and capable of being energized by fixing work holders having a couple of spring holding pawls capable of being elastically expanded and contracted to plural holding bars fixed to a peripheral frame also in parallel with one another at regular intervals. CONSTITUTION:Plural holding bars 12 are fixed to the peripheral frame 11 almost in parallel with one another, and a conductor bar 14 connected to the positive terminal of a power source is fixed to one end of the bar 12. Many work holders 13 are fixed to the holding bar 12 at regular intervals. The work holder 13 has a couple of spring holding pawls capable of elastically expanding and contracting and generating work holding power when made free, and is allowed to protrude from the holding bar 12 toward the front and rear of the peripheral frame 11. The expanding and contracting bar of the attaching and detaching device (not shown in the figure) is inserted into the bulging part of the work holder 13, and the pawls are opened and closed to efficiently attach and detach the work. The work holding frame 10 except the conductor bar 14 made of copper is preferably made of titanium on which an oxidized film is not formed by anodic oxidation. |
