[0002] A radial drilling machine is a hole processing equipment that can be used for various forms of processing such as drilling, expanding holes, reaming, tapping and scraping end faces. The rocker arm can rotate and rise and fall around the column. Usually, the spindle box is horizontally moved on the rocker arm. When processing holes on a vertical drilling machine, the centering of the tool and the workpiece is achieved by moving the workpiece. At present, when the workpiece is completed by fixed-point drilling, it is often necessary to translate the equipment so that the next drilling point corresponds to the spindle box tool. This process requires that the workpiece be accurately moved axially along a horizontal axis. However, at present, after the workpiece fixture is installed on the workbench, if adjustment is required, it needs to be disassembled and reinstalled. The process depends entirely on manual calibration by workers, and it is difficult to accurately ensure movement along the horizontal axis. If there is a skew, the drilling position will deviate.
