As shown, a robot mounting portion 11a is formed on the main bracket 11, and a portable welding robot (not shown) is mounted on the robot mounting portion 11a.

[0005]

However, as shown in FIG. 3, since the fastening bolts 13a and 13b are inevitably located on the back side of the longe 12, it is difficult to fasten and fix the main bracket 11 to the longe 12. It becomes extremely troublesome. In addition, when tightening the two tightening bolts, a large force is required at the time of tightening because the knob formed at one end of the tightening bolt is turned to tighten. Furthermore, as described above, unequal-sided unequal thickness angle steels are used for the longes, and unequal-sided unequal thickness angle irons have various plate thicknesses, so that the mounting clamp is adapted to all plate thicknesses. It is difficult.

As described above, in the conventional mounting clamp,
It is very troublesome to attach and detach the main bracket, and as a result, there is a problem that the working efficiency at the time of welding is reduced.

[0007] It is an object of the present invention to provide a robot mounting device capable of improving the work efficiency during welding.

[0008]

According to the present invention, there is provided an angle steel having a corner portion formed by a first plate portion and a second plate portion arranged at right angles to the first plate portion. A robot mounting device for mounting a robot that performs an operation on the formed longe to the longe, a main bracket having a surface on which a robot mounting portion to which the robot is mounted and abutting on the longe are formed, A pressure bracket for clamping the longe together with the main bracket, and the first and second plate portions by moving the pressure bracket toward the corner of the longe when the main bracket is in contact with the longe. Respectively, by applying force to the main bracket and the pressure bracket to pinch the longitudinal. Robot mounting apparatus characterized by having a drive means for fixing the in-bracket to the longitudinals can be obtained.

For example, the driving means includes a clamp arm connected to the main bracket so as to be rotatable with respect to a first axis connected to the main bracket and extending in a predetermined direction; A screw shaft connected to the clamp arm in a rotatable state with respect to a second axis extending in a given direction and movable in a direction perpendicular to the second axis; and one end of the screw shaft And a ratchet lever for moving the screw shaft. The pressure bracket is attached to the other end of the screw shaft so as to be rotatable with respect to a third axis extending in the predetermined direction. Installed. Then, when fixing the main bracket to the longe, the clamp arm is rotated around the first axis to move the pressure bracket to a position facing the corner of the longe. After adjustment, the clamp arm is fixed to the main bracket with a rocket pin, the ratchet lever is operated to move the screw shaft, and the pressure bracket presses the longe.
