Problems solved by technology
When the grinding head processes the blade, if the active compliance control is adopted, due to the extremely short contact time of the collision, the force response speed is not enough to make the end grinding head change the position quickly, which may easily cause impact damage to the blade surface and affect the surface integrity of the entire blade

The invention discloses an abrasive belt grinding device with an active and passive compliance mechanism switching, which includes a mounting seat for installing a grinding head assembly, and the mounting seat is provided with an active compliance mechanism capable of moving in the axial direction to adjust the pressure between the grinding head and a workpiece A passive compliance mechanism is provided between the active compliance mechanism and the grinding head assembly, so that the active compliance mechanism and the grinding head assembly are movably connected, and a locking mechanism for fixing the active compliance mechanism and the grinding head assembly is also included. The passive compliance mechanism is located between the active compliance mechanism and the grinding head assembly, and performs passive compliance during the working process of the abrasive belt grinding device where the active and passive compliance mechanisms are switched. At the same time, the abrasive belt grinding device switched between the active and passive compliance mechanism is also equipped with a locking mechanism. When active compliance is required, the locking mechanism fixes the active compliance mechanism and the grinding head assembly, so that the active compliance mechanism controls the grinding head assembly to achieve passive compliance and smoothness. Toggle between Active and Soft.
Description
technical field [0001] The invention relates to the technical field of machining equipment, in particular to an abrasive belt grinding device with an active and passive compliance mechanism switched. Background technique [0002] With the continuous improvement of the overall level of industrial manufacturing technology, the quality requirements of the industrial system for key parts are becoming more and more stringent, and modern mechanical processing generally develops in the direction of high quality, high efficiency and high product consistency. As an elastic grinding technology with "cold" processing characteristics, abrasive belt grinding is not easy to burn the surface of the workpiece after grinding, and has the dual functions of grinding and polishing at the same time. Precision and ultra-precision machining of curved parts. At present, CNC abrasive belt grinding technology has gradually replaced the traditional manual grinding and polishing operation mode, and th...
