过去,将传统的风动砂轮机安装在工业机器人的支臂上进行倒角或去毛刺等作业时,如果不根据工件的材料和硬度来调整砂轮的推压力,就难以找到最佳磨削量。若推压力太大,则磨削量过大,砂轮旋转停滞;反之,若推力太小,则工作效率太低,作业时间延长。为此,对上述磨削工具进行了改善,其结构如图所示。在气缸和活塞之间装上压簧,给砂轮施加推压力,当砂轮的心轴根据作业状况需要倾斜时,可以通过一端的球轴承和另一端的弹性材料来达到。弹性材料的弹性调节通过用压力调节器调节由外部供给的空气压力来进行。经此改善后,砂轮机不受工作条件的影响即能产生最佳推压力,因而工件磨削的均匀性好,
In the past, when a conventional pneumatic grinder was mounted on an arm of an industrial robot for chamfering or deburring, it was difficult to find the optimum amount of grinding without adjusting the pressing force of the grinder according to the material and the hardness of the workpiece . If the pressure is too large, the amount of grinding is too large, wheel rotation stagnation; the other hand, if the thrust is too small, the work efficiency is too low, extended working hours. To this end, the above-mentioned grinding tool has been improved, the structure shown in the figure. A compression spring is installed between the cylinder and the piston to apply a pressing force to the grinding wheel. When the grinding wheel mandrel is tilted according to the working condition, it can be achieved by the ball bearing on one end and the elastic material on the other end. The elastic adjustment of the elastic material is performed by adjusting the pressure of the air supplied from the outside with a pressure regulator. After this improvement, the grinder is not affected by the working conditions that can produce the best pressure, so the workpiece grinding uniformity,
