PURPOSE:To provide an electronic part fixture, which can change over the pitches of an electronic-part fixing block even under the state, in which an anvil body is lifted or lowered or turned, and can improve productivity by the increase of the mounting speed of an electronic part. CONSTITUTION:A printed board 21 is held to an anvil body 25 in an approachable and separable manner along the directions of the pitches of the leads 23 of an electronic part 22 projected to the lower section of the printed board 21. An electronic part fixture has a pair of electronic-part fixing blocks 24 having various functions for mounting and fixing the leads 23, a lifting turning gear 29 holding the anvil body 25 in a freely vertically movable manner toward the printed board 21 and in a rotatable manner around a vertical axis, and a block driving means 28 being installed to the anvil body 25 and mutually approaching, separating and driving the electronic-part fixing blocks 24. Since the block driving means 28 is lifted and lowered and rotated together with the anvil body 25, the operation of the pitch changeover of the electronic-part fixing blocks 24 is conducted at the same time as the lifting and lowering and revolution of the anvil body 25, thus improving productive efficiency by the increase of working speed of mounting fixing operation. |
