Conveying Apparatus for Machining Device

A conveyor apparatus for a machining device, comprising:

• a base carrying die formed with guide rails for guiding a machining device straightly in the lengthwise direction;
• a main screw bar mounted in the base carrying die rotatively and formed with a first spiral part continued in a direction on an outer peripheral surface;
• a sub screw bar formed with a second spiral part continued in the opposite direction from the first spiral part and rotating in association with the rotation of the main screw bar;
• a pair of engagement gears provided on one side of each of the main screw bar and the sub screw bar for transmitting rotation force from the main screw bar to the sub screw bar;
• the turret positioned to the guide rails of the base carrying die via engagement with the main screw bar and the sub screw bar to move along the guide rails according to the rotation direction of the screw bars, wherein the turret has a first coupling hole formed with a first continuous spiral groove on an inner peripheral surface to be coupled with the first spiral part and a second coupling hole formed with a second continuous spiral groove on an inner peripheral surface to be coupled with the second spiral part;
• and
• a screw rotation element for rotating the main screw bar.
