Description

TECHNICAL FIELD

[0001] The present application relates to the field of boring tools, in particular to a positive and reverse boring tool for casting processing. BACKGROUND

[0002] A positive and reverse boring tool is a special tool used for hole processing on a lathe, mainly used for processing the inner and outer surfaces of holes. The design of the positive and reverse boring tool allows it to work in both positive boring and reverse boring modes, adapting to different processing needs.

[0003] The existing positive and reverse boring tool is usually composed of important structures such as tool body, pad, positive tool clamp and reverse tool clamp, and the inserts on the positive and reverse boring tool are usually positioned and fixed by tightening screws. However, the inserts and tool body need to be disassembled and replaced regularly during use, so the repeated tightening of the screws and the force exerted by the inserts on the tightening screws during use may damage the structure of the screws. The threaded portion of the screw is constantly squeezed and rubbed during tightening, causing the threads to wear and deform, resulting in uncontrolled loosening of the tightening screw during use. Moreover, the existing boring tool does not have a device that can sense the displacement of the position of the tightening screw, so it cannot sense the loosening of the tightening screw, resulting in low safety during use.
