Problems solved by technology

[0003] See figure 1 , the existing camshaft, the positioning hole 12 provided on the shaft body 11, when drilling, the root 13 of the positioning hole 12 is prone to burrs, and it is inconvenient to remove directly. It is necessary to use a special tool after the drilling is completed. Post process deburring
The special deburring process is more complicated, and the processing technology of the camshaft is increased, which prolongs the processing time and reduces the processing efficiency

Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] See Figure 2 to Figure 3 , The camshaft provided by the embodiment of the present invention includes a shaft body 21, and a positioning hole 22 is opened on the shaft body 21, and a smooth platform 24 is provided at the root 23 of the positioning hole 22.

[0018] At present, when the positioning hole 22 is processed, burrs are often generated at the root 23 of the positioning hole 22, which affects the normal use of the camshaft to a certain extent, a...

Abstract

The invention discloses a camshaft, which comprises a shaft body on which a positioning hole is opened; a smooth platform is arranged at the root of the positioning hole, and the lower end of the smooth platform communicates with the positioning hole. In the camshaft disclosed by the present invention, a smooth platform is arranged at the root of the positioning hole, and since the lower end of the smooth platform is directly connected with the positioning hole, the burrs can be easily removed after the root of the positioning hole is processed into a smooth platform There is no need for a special follow-up process to perform a special deburring process on the root of the positioning hole. Therefore, the camshaft disclosed by the present invention can conveniently remove the burrs, thereby improving the machining efficiency.

Description

technical field [0001] The present invention relates to the technical field of mechanical components, more specifically, to a camshaft. Background technique [0002] The camshaft is a commonly used mechanical component in the mechanical field, and it is also an important part of the engine. The structure of the camshaft affects the operation of the engine. [0003] See figure 1 , the existing camshaft, the positioning hole 12 provided on the shaft body 11, when drilling, the root 13 of the positioning hole 12 is prone to burrs, and it is inconvenient to remove directly. It is necessary to use a special tool after the drilling is completed. Post-process deburring. The special deburring process is relatively complicated, and the processing technology of the camshaft is increased, the processing time is prolonged, and the processing efficiency is reduced. [0004] To sum up, how to provide a camshaft to facilitate deburring and improve processing efficiency is a problem to b...
