The invention discloses a zero searching method of a machine tool machined hole surface workpiece. The zero searching method comprises the following steps: a magnetic tool setting block with a working thickness is provided, and two side surfaces of the magnetic tool setting block in the working thickness direction are finished; one side surface of the hole surface workpiece is finished, and the magnetic tool setting block is absorbed on the side surface of the hole surface workpiece; a dial indicator is additionally mounted on a main shaft of a machine tool, the main shaft rotates to respectively detect the two side surfaces of the magnetic tool setting block, relative coordinate values of the two side surfaces of the magnetic tool setting block are respectively recorded, and measured values of the dial indicator to the two side surfaces of the magnetic tool setting block serve as correction values in detection; and a center coordinate value of the magnetic tool setting block is calculated according to the relative coordinate values and the correction values to serve as a zero coordinate of machine tool machining. The method is high in zero searching precision.
Description
technical field [0001] The invention relates to the field of calibration reference zero points of machine tools, in particular to a method for finding zero points of workpieces processed by machine tools. Background technique [0002] In mechanical processing, in order to improve the accuracy between the hole and the mounting surface, it is often necessary to ensure the distance between the hole and the surface. The hole surface distance (the distance between the side of the workpiece and the hole in the upper and lower vertical planes) tolerance requirements may reach level 6-7. The tolerance range varies between 0.01-0.05. In order to ensure the distance between the hole and the surface, it is generally necessary to use high-precision machine tools (such as high-precision coordinate boring). However, in the actual machining process, it is often difficult to ensure high-precision machining due to the difficulty in calibrating the zero point of the machine tool and the lack...
