Description

Glass rod drilling equipment calibration device and fixture level calibration method

Technical Field

The invention relates to the technical field of glass rod processing equipment, and in particular to a glass rod drilling equipment calibration device and a fixture level calibration method.

Background technique

In the actual production process, the fixture parts that come into contact with the product on the centering shaft fixture of the glass rod drilling machine are made of ABS. Since ABS will deform significantly after long-term use, it is necessary to regularly check whether the tooling fixture meets the production standards.

Failure to use a dial gauge to check will result in the workpiece not being clamped on the horizontal axis, and it will be impossible to detect whether the fixture is deformed in time. The fixture is checked by extending the tool bar and checking with a feeler gauge. Since the longer the tool bar is extended, the worse the stability is, and the inspection error is too large, it is necessary to use a dial indicator to check.

The machine tool has a guide sleeve and a support sleeve between the spindle and the fixture. The machine tool spindle is limited by its travel and cannot be calibrated close to the fixture. The conventional dial indicator bracket is not long enough to complete the measurement. Simply increasing the length of the dial indicator bracket will reduce stability and increase inspection errors.
