Product Description
Quick locking bolts kit and fixture jigs for D28 D16 welding tables
Locking pins are used to fasten modules and modules, modules and platforms, among which quick locking pins are already one of the products in flexible combination fixtures.
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.

Product Features
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;
Φ28*75,Φ28*50 different sizes 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 ±0.05mm, and the hole diameter error is +0.05.
Why do 3D welding locking pin bolts sometimes fail to insert?
When using the 3D flexible welding table, the quick locking pin cannot be inserted. This is because the outer diameter of the quick locking pin does not match the accuracy of the inner diameter of the hole on the three-dimensional flexible welding platform. In order to reduce costs, the three-dimensional flexible welding platforms produced by some factories use HT200 material. The working surface has many defects. The holes are processed by ordinary machine tools. The hole position and flatness cannot be guaranteed. The quick locking pins are also processed by ordinary machine tools. , the accuracy cannot be guaranteed, and the products produced in this way will be unqualified, so the locking pin will not be inserted or will keep shaking when inserted. The holes of The 3D flexible welding table with 28mm or 16mm diameter produced by Wuxi Lemar are processed by secondary CNC precision boring, so as to ensure that the error of the hole diameter is within the range of +0.05mm. The quick locking pin is also processed by CNC, and the pin error is h7 , the 3D flexible nitrided welding table cooperates well with the quick locking pin, so there will be no problem that the locking pin cannot be inserted.
