Method for assembling dual-head pulling rods

A method for assembling dual-head pulling rods, using a dual-head pulling rod assembling system to mount pulling heads at two ends of a rod body of each said dual-head pulling rod through threaded connection, the system comprising:

• a foundation, on which a rod dispensing device, an inclined guiding plate, a conveying flap, a head dispensing device, a head mounting unit, a clamping device, an assembling device and a V-shaped output channel are installed, and the method comprising steps of:
• Step 1:
• the rod dispensing device dispensing said rod bodies stored therein one by one by gravity, and the head dispensing device dispensing said pulling heads stored therein one by one by gravity;
• Step 2:
• the inclined guiding plate using a ramp thereof to guide the dispensed rod bodies;
• Step 3:
• the conveying flap, at a tilted-up input position thereof, receiving and conveying each said rod body guided thereto by the inclined guiding plate to the clamping device;
• Step 4:
• first, the head mounting unit receiving the pulling heads dispensed by the head dispensing device;
• then the head mounting unit receiving the rod bodies coming from the conveying flap;
• secondary, the head mounting unit axially pushing the pulling heads to corresponding sockets inlaid in the ends of each said rod body;
• and the head mounting unit departing from the pulling heads while the rod body advancing to the clamping device along the conveying flap;
• Step 5:
• the clamping device horizontally clamping opposite laterals of the rod body;
• Step 6:
• the assembling device threadedly connecting the pulling heads to the ends of the rod body;
• Step 7:
• the clamping device releasing the rod body, and the conveying flap, at a tilted-down position thereof, receiving the rod body with the pulling heads attached thereto on the clamping device and output the rod body to the V-shaped output channel;
• and
• Step 8:
• the V-shaped output channel axially advancing the rod body output by the conveying flap to a position for subsequent processing.
