Claims

[Claims for Utility Model Registration] 1. A first arm 5 that pivots around a first shaft 10.
A screw tightening device is attached to the tip of the second arm 25 of a horizontal multi-joint robot consisting of a second arm 25 that rotates around a second shaft attached to the tip of the first arm 5, and the screw tightening device is attached to the tip of the second arm 25. is provided with a motor and a speed reducer 14 on its upper part, and its output shaft 35 is connected to a clutch shaft 41 via clutch plates 45 and 46, and the clutch shaft 41 is inserted into a guide tube 50 via a ball key 39. The outer cylinder 42 is connected to the motor and reducer 1.
4. The clutch plates 45, 46 and the clutch shaft 41 are held and built in, and are moved up and down using the bearing 36 of the frame 57 fixed to the second arm 25 as a guide.
The guide tube 50 is attached to the lower end of the outer tube 42 in a state in which it is pressed downward by a coil spring 49, and the lower end of the inner tube 50 is formed of a thin spring plate and has a screw having a pair of legs 67. The leg 67 is inserted into the long groove 51 cut out in the guide tube 50 in the receiver 60, and the leg 67
7 is fixed to the long groove 51 without being restricted, and a hole 61 is formed on the side surface of the guide tube 50 through which a screw supplied from the screw supply fitting 55 can pass, and the first arm 5. The inner tube 50, which has been positioned at a predetermined location by the second arm 25, is lowered by the operation of the air cylinder 32 and comes into contact with the upper surface of the screw hole of the workpiece, and then the screw supply fitting is rotated and lowered by the bit 40. The automatic screw tightening device is characterized in that the screw supplied from the screw receiver 55 and held in the screw receiver 60 is screwed into the screw hole while pushing open the legs 67 of the screw receiver 60. 2. The automatic screw tightening device according to claim 1, wherein the screw receiver is constructed of a plate spring and a split screw holding fitting, and is installed in the long groove of the guide tube. 3. If the engaging clutch that connects the output shaft and clutch shaft of the motor is overloaded and slippage occurs between the clutch plate on the driven side and the clutch plate on the motor side, the safety device 65 is activated and the clutch on the motor side is Installed limit switch operating plate 7
1. The automatic screw tightening device according to claim 1 or 2, which has a safety device for activating a limit switch and stopping the rotation of the motor.
