Title:
APPARATUS FOR MACHINING HEADREST STAY ROD GROOVE FOR VEHICLE, AND METHOD FOR MACHINING HEADREST STAY ROD GROOVE FOR VEHICLE BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/058378
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for machining a headrest stay rod groove for a vehicle and a method for machining a headrest stay rod groove for a vehicle by using same, and comprises: a fixing mold for fixing a stay rod; a tapered block arranged to face the stay rod; a roller installation member which is inserted between the tapered block and the stay rod and moved up/down while in contact with the tapered block; a roller which is installed on the roller installation member and machines a groove in the stay rod; and a body frame in which the fixing mold, the tapered block, and the roller installation member are installed along with respective moving up/down devices. Therefore, one groove can be machined by one roller, and thus, the number of total rollers that are necessary for machining grooves, and a machining degree can be precisely adjusted so as to prevent the generation of burrs when machining the grooves.
