Description

Technical Field

[0002] Shaft parts are rotating parts whose length is greater than their diameter. They are generally composed of the outer cylindrical surface, conical surface, inner hole and thread and corresponding end faces of the concentric shaft. They are mainly used to support transmission components, transmit torque and bear load shaft parts. The processing of shaft parts includes cutting processing to ensure the precision of the produced shaft parts.

[0003] The existing shaft parts cutting device is not fully functional in use. Due to the different sizes and types of workpieces, different types of cutting processes usually require different fixtures, and it is necessary to replace the fixtures that match them. Replacing the fixtures is time-consuming and labor-intensive, which increases production costs and is not conducive to production and processing. At the same time, debris will splash during processing, which can easily cause accidental injuries to people. Utility Model Content
