High-precision tool setting device and tool setting method of micro-diameter milling tool

Abstract

The invention discloses a high-precision tool setting device and tool setting method of a micro-diameter milling tool, and belongs to the technical field of mechanical automation. The device comprises a laser device, the micro-diameter milling tool, an electric spindle, a CCD chip, an X-direction high-precision sliding table, a Y-direction high-precision sliding table, a Z-direction high-precision sliding table, an image signal processing unit, a motor control unit, a laser device control unit and a computer master control unit. Z-direction high-precision tool setting of the micro-diameter milling tool at any position in the XY plane is achieved, and the laser coaxial holographic imaging technology and the super-resolution image reconstruction technology are utilized for achieving automatic measuring of a tool setting gap, so that the error caused by deformation generated by the contact between the milling tool and a workpiece during traditional try cutting is prevented, and meanwhile, the field depth error caused by the fact that the milling tool and the workpiece are not located in the same image imaging face is avoided. The device is low in cost, easy to operate, capable of being mounted in a distributed manner within the limited work space, and suitable for high-precision tool setting of a micro milling tool, a common milling tool and a numerical control milling tool.

Description

Technical field [0001] The invention belongs to the technical field of mechanical automation, and specifically relates to a high-precision tool setting device for a micro-diameter milling cutter and a tool setting method thereof. Background technique [0002] In the high-speed micro-milling process, the accuracy of tool setting directly affects the surface accuracy and processing quality of the workpiece. As the diameter of the currently used milling cutter is getting smaller and smaller, the precision requirements for the tool setting of the micro-milling machine are getting higher and higher, and a little carelessness will cause the tool to break and break. The existing tool setting methods include trial-cutting tool setting, laser direct-lighting tool setting, laser diffraction method, image method tool setting, etc. Trial-cutting method is especially useful for micro-diameter milling cutters in high-speed machining. The following milling cutters are prone to reduce the accur...
