IPC: B24B41/047
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To make a robot handle follow in the inclination and bending of a steel plate, optimize the pressing force to the steel plate, and make it constant. SOLUTION: An arm fixing plate 1 and a grinding stone fixing plate 2 are connected through plural cylinders in which rotatable pillow balls 5, 6 are fixed to both ends, and a guide bar 10 having a rotating link mechanism 8 and capable of sliding. Each cylinder and the guide bar 10 are optionally elongated, contracted, and slid within a stroke against the inclination and bending of a steel plate, and flexibly inclines the grinding stone in the X and Y directions to follow in the steel plate. By applying back pressure to each cylinder, the optimum pressing force is obtained without having effect on the dead weight of the robot handle. By installing an escape valve in an air circuit on the projecting side and the returning side of a rod of the cylinder, and constant pressing force is obtained independent of the amount of coming in and out of a stroke.
