locking pin

There are five concentric steel balls in the body of the 28mm or 16mm quick locking pin. When the locking pin thread is loosened, the steel balls will automatically retract and lock. At this time, the locking pin can be inserted into or pulled out of the round hole of the locked work-piece. When in use, the locking pin is inserted into the hole of the locked work-piece and the head of the locking pin is gradually tightened by hand. At the same time, the steel ball gradually protrudes and locks automatically.

The quick locking pin of the 3D welding platform has a large clamping range. After the lock pin is tightened, it can reach a clamping force of 50KN and a shearing force of 250KN;
Quick locking pin,Countersunk head locking pin,Inner six conrners connect locking pin,Magnetic pin and other different pin bolts are available;

D28 D16 welding table served by Quick Locking pin is finely machined by a high-precision CNC gantry milling machine. The flatness of the working surface is 5 wires per meter, the hole spacing error is ¡À0.05mm, and the hole diameter error is +0.05.
