Machining and positioning tool for precise electronic parts

The utility model relates to the technical field of part positioning equipment, and discloses a precision electronic part machining positioning tool which comprises a base, a mounting block rotationally connected to the interior of the base and a positioning clamp arranged at the top of the mounting block. And the output end of the rotating motor is in key connection with a rotating column, the top end of the rotating column is screwed to the bottom of the mounting block, and two movable cavities are formed in the base. According to the machining and positioning tool for the precise electronic parts, through cooperation of a connecting rope and a moving plate, when a swing block rotates to eject a movable block to move downwards, an ejecting block can pull the moving plate to move in the mode of ejecting the connecting rope, and therefore a clamping roller can be disengaged from a gear; and at the moment, the rotating motor is started to enable the mounting block to drive the part clamped at the top of the mo
