Abstract

PURPOSE:To enable a rotary part to be assembled by unmanned operation, by aligning a rolling bearing nut groove to be tightened in the position of a tooth of a rolling bearing washer and automatically detecting said position so as to fold the tooth of the washer, in the case of locking work of looseness for the rotary part or the like. CONSTITUTION:After a rolling bearing is press fitted to a shaft 6 of the assembly device, arranging a groove inserting the tongue part of a bearing washer in the fixed direction and inserting a washer 2 further screwing a nut 1 about a turn to be mounted, by a robot or the like positioning is performed immediately below a tightening device 14 by a self-propelled running bed 8. Next, the nut is chucked by a chuck 15, rotated and stopped at a point of time completing its tightening by detecting a detecting hole, provided in an indexing disc 18 and numbering a quantity multiplying a number of the grooves in the nut 1 and a number of teeth in the washer 2, through a photoelectric switch 21, thus the groove is aligned to a folding position of the tooth of the washer 2. And next, the rolling bearing is positioned below a folding device 27 by releasing the chuck 15, and a folding pawl 30 is positioned in a folding position by a detecting disc 34 and a photoelectric switch 35, thus performing folding. In such way, lcoking work of looseness of a rotary part or the like can be automatically performed.

After the shaft bearing 5 is press-fitted into the shaft 6 shown in FIG. 1, the keyway (not shown) of the shaft 6 is used to attach it to the stand 9 of the self-propelled traveling platform 8 shown in FIG. 2 by a robot or the like. The direction of the groove into which the tongue 7 of the bearing washer is inserted (keeping the direction of rotation constant) Insert the washer 2 into the shaft 6, and then attach the roller bearing to the robot, etc., to the shaft 6.
Screw it in about one turn to install it (tightening chuck 1!1
It is also possible to supply and hold it with a 14-point robot, etc.). After this, the shaft 6 is moved to the second self-propelled carriage 8 on the running rail lo.
The tightening shown in the figure is done by positioning the device 14 directly below the frame 11.
The nut 14 is mounted on a rail 12 fixed perpendicularly to the rail 12 so that it can be raised and lowered by a cylinder 13.The tightening is performed by lowering the nut 1 to the height of the bearing nut 1 by rolling it with the cylinder 14t-cylinder 13, and tightening it by rolling it with the chuck 15 of the device 14. Chuck the shaft bearing nut 1. Thereafter, the drive motor 16 rotates the chuck 15'fr and tightens it. At this time, the tightening device 14 balances its own weight with the air cylinder 17 and is allowed to descend freely. In addition, a chuck force is applied so that the jaws of the chuck 15 roll into the grooves 4 of the bearing nut 1 during the tightening process. The tightening operation is stopped using a pressure switch (not shown) when a constant torque is reached. after this,
The drive motor 16 is controlled by a pressure control valve (not shown) or the like.
1 provided on the bearing washer 2 (switch to high pressure, roll)
The chuck 15 is rotated to a position where one of the seven teeth 3 and one of the four grooves 4 provided in the nut 1 for the roller bearing are closest to each other. This retightening process will be explained in detail with reference to FIGS. 3 and 4.

The chucks 15 shown in FIG. 3 are provided at four locations at right angles, and an index disk 18 is attached so as to rotate in the same manner as the shaft 19. is the total number of grooves 4 provided in the rolling bearing nut 1 and the number of teeth 3 of the rolling bearing washer 2, i.e., 4X17=68 detection holes 2.
0, and the position of this detection hole 20 is set by the photoelectric switch 21.
The rotation of the drive motor 17 is stopped approximately at the center of the detection hole. This operation causes the chuck 15 at the tip of the drive motor 17 to be moved to any position in the chuck 15, that is, to the groove 4 of the nut 1 for the roller bearing and the tooth 3 of the washer 2 for the υ bearing.
This means that one of the positions is correct. Furthermore, in order to detect which of the above positions matches the groove 4 of the rolling bearing nut 1 and the teeth 3 of the rolling bearing washer 2, that is, the bending position where locking is performed, it is necessary to In the index disk 22 at the bending position that rotates the same as the rotating shaft 19 in FIG.
17 photoelectric switches 24 corresponding to the teeth 3 of the roller bearing washer 2 are equally divided and fixed on the outside thereof, and the position detected by the photoelectric switch 24 of the detection hole 23 is determined by the roller shaft. It is detected that the tooth 3 is at the bending position based on the tongue 7 of the bearing washer 2. For example, in FIG. 5, a position 26 where the detection hole 23 of the index disk 22 and the photoelectric switch 24 match is the bending position.
