Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tool processing, in particular to a double-one-line laser cross combination cross positioning device. Background Art

[0002] The electric spindle used for engraving is a key component in engraving machinery. It integrates the functions of the motor and the spindle, and drives the engraving tool for precise processing through high-speed rotation. In the process of CNC machine tools, accurately adjusting the workpiece position and confirming the position of the tool center point are key links to ensure processing accuracy. Traditional methods, such as using a sharp knife to descend and observe and adjust, are applicable to some types of tools, but for coarse-tipped tools such as flat-bottomed milling cutters or ball-end cutters, this method is not feasible because the tool head is coarse and difficult to observe. In addition, the laser cross positioning devices on the market often have the problem of not coinciding with the tool center, that is, there is an offset between the laser line and the tool center, which leads to limited positioning accuracy and is difficult to meet the needs of high-precision processing.
