In-situ detecting equipment for abrasion on rear face of turning tool

Abstract

The invention discloses in-situ detecting equipment for abrasion on the rear face of a turning tool. The in-situ detecting equipment comprises an imaging device and a pose and position adjusting device, wherein the imaging device comprises a camera, a telecentric lens and coaxial light sources, the telecentric lens is mounted on the camera, and the coaxial light sources are fixed at the tail end of the telecentric lens; the pixel of the camera is not lower than 200w, and the chip of the camera is not smaller than 1 / 1.8 inch in size; the distortion factor of the telecentric lens is not higher than 0.02 percent; the image resolution of the combination of the camera and the telecentric lens is not lower than 400 pixel / mm, and the entire length is not longer than 150 mm; and the pose and position adjusting device is used for achieving multi-degree-of-freedom precision adjustment of the imaging device. During the work, the imaging device is fixed on one side, positioned on the outer normal of the rear face of the turning tool, of a lathe lateral displacement planker through the pose and position adjusting device. The in-situ detecting equipment provided by the invention has the advantages of high measuring accuracy, convenience in measurement and the like, and is applicable to abrasion on the rear face of the turning tool.

Description

technical field [0001] The invention belongs to the field of tool wear monitoring, and more specifically relates to an in-situ detection device for flank wear of a turning tool. Background technique [0002] The turning tool is the main forming tool in turning, and the wear and damage of the tool are the main factors affecting the cutting quality. After the tool is worn, the machining accuracy of the workpiece is reduced, the surface integrity is deteriorated, and the cutting force is further increased and the cutting temperature is increased, which further reduces the tool life and directly affects the processing cost and processing efficiency. With the automation, high speed and intelligence of the machining process, the detection of the working state of the tool has become an important part of the monitoring of the modern turning process. [0003] The wear type of the turning tool can be divided into flank wear, crater wear, chipping, crushing and other forms according t...
