TECHNICAL FIELD
[0001] The present application relates to the technical field of grinding wheel detection equipment, in particular to a grinding wheel flatness online detection device and method based on a 3D line-scan laser camera. BACKGROUND
[0002] Currently, there is no efficient and accurate detection device and method for the flatness and geometric shape of large flat double-end-face grinding wheels. The biggest difference between double-end-face and single-end-face grinding machines and ordinary cylindrical or internal grinding machines is that the end-face grinding machine grinding wheel is used for full contact between the grinding wheel surface and the workpiece surface for large-area simultaneous force grinding, while the force point of the cylindrical or internal grinding machine grinding wheel can be approximately regarded as a line. Therefore, the end-face grinding machine often uses a large flat grinding wheel, and the flatness of the grinding wheel has a great influence on the grinding effect of the workpiece.
[0003] During the grinding operation of the grinding machine, the grinding wheel needs to be frequently dressed as it wears. In order to avoid the assembly error caused by frequent assembly and disassembly of the grinding wheel and to improve the production efficiency, a grinding wheel dressing device is provided on the existing end-face grinding machine to dress the grinding wheel online. However, when detecting the flatness of the dressed grinding wheel, due to the structure of the grinding machine, the traditional online detection of the position and flatness of the grinding wheel of the grinding machine can only use a dial gauge to measure. The dial gauge pointer can only detect the size data at a certain position or on the same diameter in a point or line manner. Using this method to detect all positions of the grinding wheel not only takes a long time, but also the detection data is inaccurate and may miss detection. Moreover, in the existing technology, the dressing parameters are manually set according to the measurement results, which may not be accurate.
[0004] Patent No. CN207300183U discloses a laser measuring device for thin sheet grinding wheel flatness detection. It is mentioned that a laser sensor is used to measure the flatness of the grinding wheel. However, the laser sensor has a limited ring width and can only be used for line detection, which cannot achieve large flat detection. Moreover, this detection method needs to disassemble the grinding wheel for offline detection, which not only takes a long time, but also it is difficult to ensure the repeated positioning accuracy after reinstallation, thereby affecting the grinding accuracy of the grinding wheel.
