[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for simultaneously holding a plurality of workpieces which need to be processed while being rotated and tilted.

[0002]

Conventionally, is tilted while rotating the workpiece, for example, a work rotating device for subjected to laser processing (not shown) is a chuck for lifting the workpiece bunch does not have the normal one only.

[0003]

[Problems to be Solved by the Invention] When only a single chuck is provided, when a large number of works are to be machined, the work must be attached and detached for each work. However, there is a problem that the ratio of the time required for attaching and detaching the work to the workpiece increases, and the productivity decreases.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to an elongated tilting frame having both ends in the longitudinal direction supported by a fixed frame, and a plurality of reducers disposed in the longitudinal direction of the tilting frame.
And the transmission and penetrate in the longitudinal direction of the tilting frame and
An input shaft of each said speed reducer connected by hand,
The tilt frame attached to the output shaft of each speed reducer
Multiple work rotating chucks arranged in the machine direction
The above problem was solved by an apparatus having:

[0005]

Since the input shafts of the speed reducers are connected to each other by a joint, the speed reducers are simultaneously operated. For this reason, each of the chucks connected to the speed reducer is simultaneously rotated at a reduced speed. Further, when the tilting frame tilts, each reduction gear and each chuck also tilt at the same time. Therefore, the rotary tilting device is a device that can hold a plurality of works at once, tilt the work while rotating the work, and subject the work to, for example, laser processing.

In FIG. 1, a chuck rotation motor 34 is provided at the right end of the tilting frame 14. The motor 34 is a servomotor, and the rotation shaft 35 is connected to the input shaft 41 of the rightmost reduction gear 21 by a timing belt 36.

In FIG. 1 and FIG. 2, a speed reducer 4 integrated with a chuck tilting motor 45 is provided at the left end of the fixed frame 13.
6 are provided. The output shaft 47 of the speed reducer 46 is connected to the rotation support shaft 12 of the tilting frame 14. Cha
The chuck tilting motor 45 is a servomotor that simultaneously tilts the chucks 51, 52, and 53 in the direction of arrow B (see FIG. 1) together with the tilting frame 14 via the speed reducer 46.

A work tilt origin detecting mechanism 54 is provided at the left end of the output shaft 47 of the speed reducer 45. The work tilt origin detection mechanism 54 is a mechanism that sets and detects a tilt start position and a tilt range of the work through rotation of the output shaft 47 of the speed reducer 46. The output shaft 47 passes through the housing 58 of the speed reducer 46. The tilt origin detection mechanism 54 (see FIG. 5) is provided on the output shaft 47 of the speed reducer 46.

The input shafts 41, 42, 43 of the respective speed reducers 21, 22, 23 rotate simultaneously because they are connected by the joints 61, 62. The output shaft is decelerated and rotated by the rotation of the input shafts 41, 42, 43,
Simultaneously rotate 52 and 53 in the direction of arrow A (see FIGS. 1 and 2). If the reduction ratios of the respective reduction gears are different, the rotation angles of the respective workpieces are different, so that different processing can be performed simultaneously for each of the workpieces.

3 is also integrally tilted in the direction of arrow B. Each motor 3
The rotation of 4, 45 is controlled by a known NC control.

As described above, the rotary tilting device 10 can perform complicated laser processing on a work by tilting the chucks 51, 52, 53 while rotating them. The works are processed one by one or all at once. Therefore, the work of attaching and detaching three works can be performed at one time, so that the efficiency of the processing work is improved.

Instead of the chuck tilting motor 45 and the speed reducer 46, the chucks 51, 52, 53 are shown by a known manual worm gear speed reducer 71 shown in FIGS.
May be tilted. In this case, the operator can
By manually rotating the handle 73 while viewing (see FIG. 7), the tilting frame 14 and the chucks 51, 52, 53 are tilted integrally. The manual worm gear reducer 71 is provided with a lock lever 74 (see FIGS. 6 and 7) for locking the rotation support shaft 12 (see FIG. 1) of the tilting frame 14.
