A camshaft half-round key pressing machine

Abstract

The invention discloses a press-fit machine for the woodruff keys of a camshaft. The press-fit machine for the woodruff keys of the camshaft comprises a bottom plate (1), a location device for fixing the camshaft, and a storage bin (14) for storing the woodruff keys, wherein the discharge port of the storage bin (14) and the installation positions of the woodruff keys on the camshaft are correspondingly arranged; a feeding mechanism for pushing the woodruff keys to the installation positions one by one and an impact hammer (3) for installing the woodruff keys on the camshaft in a stamping manner are arranged in the installation direction of the woodruff keys. The press-fit machine for the woodruff keys of the camshaft provided by the invention is capable of replacing manual press-fit, convenient to use, capable of reducing the labour intensity of workers, and capable of ensuring product quality while increasing working efficiency.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and more specifically relates to a camshaft half-round key pressing machine. Background technique [0002] The camshaft is the core component of the engine's gas distribution system. The half-round key is installed on the keyway of the camshaft to transmit torque and drive the opening and closing of the intake and exhaust valves according to the gas distribution requirements. The semicircular key and the keyway on the camshaft adopt an interference fit. Most engine manufacturers use manual knocking when installing the semicircular key. Because the assembled parts are too small, it is not easy to install. In the production environment, the labor intensity of manual knocking and assembly is high, and the work efficiency is low. In addition, manual knocking and pressing will cause uneven force on the workpiece, and the consistency cannot be guaranteed, which will affect the quality of the pr...

AI Technical Summary

Problems solved by technology

The half-round key and the keyway on the camshaft adopt an interference fit. Most manufacturers of engines use manual knocking when installing the half-round key. Because the assembled parts are too small, it is not easy to install. In the production environment, manual knocking and assembly are labor-intensive and work efficiency is low

In addition, manual percussion and press-fitting lead to uneven force on the workpiece, and the consistency cannot be guaranteed, which in turn affects the quality of the product. There may also be copper scraps inside the engine, which poses a hidden danger to the quality of the product.
