The invention discloses a clamping device of an eight-
station cold heading
machine. The clamping device comprises a clamping table mechanism and a clamping core mechanism, wherein the clamping table mechanism is connected with the clamping core mechanism, the clamping table mechanism comprises a clamp box, a clamping table connecting rod and a clamping table oscillating rod, the clamping table connecting rod is connected with the clamping table oscillating rod, the clamping table oscillating rod is installed in the clamp box, a clamping table oscillating rod shaft is connected to the clamping table oscillating rod, a guide gear is arranged on the clamping table oscillating rod shaft, the clamping core mechanism comprises a clamping core shaft and a clamping
assembly, a rolling gear is arranged on the upper part of the clamping core shaft, the rolling gear is engaged with the guide gear, the clamping table connecting rod and the clamping table oscillating rod are connected to the middle of the clamping core shaft, and the clamping
assembly is connected to the lower part of the clamping core shaft. The device has the advantages of simple and compact structure, high degree of
automation, stable working performance and high production efficiency, both the clamping table connecting rod and the clamping table oscillating rod are wrapped in the clamp box, so that the normal movement of the clamping table mechanism is not influenced by the outside adverse
working environment, and the exposed part of equipment is reduced, so that materials are saved.
