Core rod centering and stuffing device

Abstract

The invention relates to the technical field of steel tube drift diameter gauge and in particular relates to a core rod centering and stuffing device which comprises a push mechanism, a jacking mechanism, a waiting rack, a lifting mechanism and a feeding rack, wherein the feeding rack and the waiting rack are respectively arranged on the left side and the right side of the lifting mechanism; the lifting mechanism comprises a lifting platform, a lifting cylinder and a lifting cylinder support base; the top of the piston rod of the lifting cylinder is fixedly connected with the bottom of the lifting platform; the bottom of the lifting cylinder is fixedly arranged on the lifting cylinder support base; the jacking mechanism comprises a jacking electric cylinder, a V-shaped platform and a jacking electric cylinder support base; the bottom of the V-shaped platform is fixedly connected with the top of the piston rod of the jacking cylinder; the jacking electric cylinder is fixedly arranged onthe jacking electric cylinder support base. With the combination of the push mechanism, the jacking mechanism and the lifting mechanism, automation can be conveniently achieved, the production efficiency can be improved, and the working intensity of operators can be alleviated.

Description

technical field [0001] The invention relates to the technical field of steel pipe diameters, in particular to a mandrel centering and plugging device. Background technique [0002] The diameter of the steel pipe is one of the important steps to detect whether the quality of the steel pipe is up to standard. At present, there are two main methods for the diameter of the steel pipe: one is the mechanical method, which uses a mechanical method to push the mandrel to detect the inside of the steel pipe; the other is the pneumatic method. The diameter method uses a pneumatic method to push the mandrel to detect the inside of the steel pipe. Due to the high pass efficiency and the ease of automation, the pneumatic pass method is widely used in the steel pipe production line. [0003] The main working principle of the air pressure calibrating machine: insert the mandrel into one end of the tested pipe, and use high air pressure to act on the tail of the mandrel, so that the mandre...
