PURPOSE:To improve the rigidity of a robot by pressuring a cone type supporting material having a hole capable of passing a tool to a work through an elastic member and decreasing a dynamic load to a robot arm. CONSTITUTION:Between an arm 26 and a flange section 31 at the low edge of a drill unit supporting member 11, a leaf spring 32 is placed as an elastic member. The arm 26 rubbs and moves on the peripheral face of the supporting member 11 and can press a conical supporting member 12 toward a preload direction through the spring 32. Under the pressed condition, a drill 17 is lowered and a work 8 is machined by a drill. The dynamic load such as vibration etc. given to the drill 17, is transmitted to the arm 26 of a robot 5 through the leaf spring 32 and the dynamic load on the robot is decreased whereby the apparent rigidity of the robot is increased. |
