Abstract

The invention provides milling, grinding and polishing in-situ imaging integrated intelligent equipment and a machining method. The milling, grinding and polishing in-situ imaging integrated intelligent equipment comprises a lathe bed, a measuring cabin and a machining cabin, wherein the measuring cabin and the machining cabin are arranged in the lathe bed; a feeding and discharging mechanism used for grabbing a workpiece is arranged in the measuring cabin; a five-axis linkage system and a tool selection mechanism are arranged in the machining cabin; the five-axis linkage system comprises a tool displacement mechanism used for adjusting the space pose of a tool and a workpiece pose adjusting mechanism used for adjusting the space pose of the workpiece to be trimmed; the tool selection mechanism comprises a chain type tool magazine and a tool changer which are arranged in the machining cabin; a plurality of tool installation positions are distributed on the chain type tool magazine; a milling cutter, a grinding wheel and a polishing wheel are arranged in the tool installation positions correspondingly; the tool displacement mechanism comprises a spindle box; a spindle used for installing the tool is arranged in the spindle box; and a plurality of holes used for spraying milling fluid, grinding fluid and polishing fluid are further formed in the spindle box. According to the milling, grinding and polishing in-situ imaging integrated intelligent equipment and the machining method, in the machining process, secondary clamping is avoided, the same feed path is achieved in the milling, grinding and polishing processes, and the accuracy of form and position of a machined part can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to an integrated intelligent equipment and processing method for in-situ imaging of milling, grinding and polishing. Background technique [0002] High-performance parts with complex curved surfaces are usually processed by five-axis simultaneous milling. After processing, the surface roughness Ra≥3.2μm, while high-performance parts require surface roughness Ra≤0.8μm. Service requirements for high-performance parts with complex surfaces. Therefore, under the current technical conditions, high-performance parts with complex curved surfaces still need grinding machines and polishing equipment for further processing after milling to meet service requirements. This will lead to secondary clamping during part processing, seriously affecting its shape and position accuracy. Existing mechanical grinding and polishing methods, such as soft abrasive belt grinding an...
