AI Technical Summary

Technical Problem

In chain-type tool magazines, the slippage between the transport unit and the spindle causes the tool holder at the tool change position to shift. Existing calibration methods are prone to wear, and conventional mechanical calibration is not accurate enough.

Method used

It employs a tool magazine component, a tool holder component, and a comparison component. It utilizes offset grooves, pins, and cylinders to perform pre-correction calibration through movable offset blocks and magnetic repulsion. Combined with a rangefinder and sensors, it monitors the calibration process in real time, avoiding wear caused by direct insertion calibration. The correction force is adjusted through an intelligent control system.

Benefits of technology

This achieves stable and accurate calibration of the tool holder components, avoids wear, improves the effectiveness and safety of calibration, and enhances the intelligence and robustness of the device.

Abstract

The present application belongs to the technical field of tool magazines, and in particular to a tool magazine tool position changing calibration device. The following scheme is proposed, which comprises a tool magazine component, a tool sleeve component, and a comparison component. The comparison component is provided with a pin rod. The top end of the tool sleeve component is provided with an offset slot. The bottom end of the offset slot is provided with a calibration hole that is adapted to the end of the pin rod. The top end of the pin rod is connected with a gas cylinder. A spring one is connected between the tool magazine component and the comparison component. The tool magazine component can move along the extension direction of the pin rod. The width of the tool magazine component is smaller than the width of the offset slot. The two sides of the tool magazine component are provided with offset blocks that can move outward. The present application is aimed at the calibration operation of the position of the tool sleeve in the tool magazine tool position changing. The offset blocks on the two sides can pre-push and correct the tool sleeve component before the pin rod is inserted. The problem of wear of the pin rod or the calibration hole caused by the offset of the tool sleeve in the traditional direct insertion type calibration is solved. The stability and effectiveness of long-term and multiple calibrations are ensured.
