DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a process for wiring cables of a tilted rotary table.

[0002]

2. Description of the Related Art In a conventional inclined rotary table, a spring is provided by a binding band or the like at several places so that two cables coming out of an electric motor do not fall apart. The length was set aside so that it would fit in the outer frame that covered the motor. The position and number of cables to be bundled together, the length to allow extra space for the cables, and the way in which the cables are inserted into the outer frame of the main unit (the state of the cable being swung, the position) are left to the operator and differ depending on the operator. I was

[0003]

The cable moves following the rotation of a rotating body provided with a motor for tilting the tilting rotary table. At this time, the movement of the cable within the outer frame of the main body is not fixed and cannot be predicted. For this reason, when the rotating body rotates, the cable is repeatedly bent due to bending, rubbed, caught, or pulled to cause a disconnection at a connection portion with the electric motor, causing troubles. Further, the length of the cable and the manner of holding the cable differ depending on the operator, so that the above-described trouble is likely to occur. Thus, such a problem is solved by making the movement of the cable following the rotation of the rotating body constant.

[0004]

SUMMARY OF THE INVENTION The present invention provides a main body, a rotating body supported by the main body and rotating in association with the inclination of a table surface, an electric motor for inclination attached to the rotating body, and the electric motor. The cable is fixed along an elastically deformable belt-shaped cable guide, and the cable guide has one end provided on a rotating support provided on a rotating body and the other end provided on a main body. And fixed in a shape that can be expanded and contracted in the radial direction of the electric motor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, an inclined rotary table has a U-shaped main body which has side bodies 11 erected on both sides and which is open upward, and a side which is open to an upper part of the main body. Table body 12 provided with a table surface supported by a rectangular body 11
The one side body 11 is provided with a rotating body 2 supporting a table body 12 and an electric motor 1 for tilting.

FIG. 2 is a sectional view taken along the line XX of FIG. 1, and FIG. 3 is a sectional view taken along the line YOY of FIG. The rotating body 2 and the electric motor 1 for tilting are provided on the side body 11 at the tip of the tilt axis of the table body 12.
And the electric motor 1 rotate integrally. Cable guide 4
In order to support both ends of the rotating body 2,
Is provided with a rotating column 5, and both ends of the cable guide 4 are attached to the fixed column 6 and the rotating column 5, respectively, in a spiral shape larger than the diameter of the electric motor 1. FIG. 4 is a perspective view of the cable guide 4 attached to two columns.
The two cables 3 inserted into the lateral body 11 from outside are:
The cable 3 and the cable guide 4 are guided so as not to be separated from each other by being guided to the electric motor 1 along the cable guide 4 connecting the fixed support 6 to the rotating support 5.

FIG. 5A shows a state of the cable guide when the cable guide 4 is attached to the fixed support 6 in a counterclockwise direction so as to extend outward from the rotary support 5. When the rotating body 2 rotates clockwise, as shown in FIG. 5B, the rotating support 5 moves clockwise, and the cable guide 4 moves following the clockwise movement. At this time,
Since the fixed support 6 does not move, the cable support 4 attached to the rotary support 5 is reduced so that one end of the cable guide 4 is wound toward the center. On the other hand, when the rotating body 2 rotates counterclockwise,
As shown in FIG. 5C, the rotating support 5 moves counterclockwise, and the cable guide 4 moves accordingly. At this time, fixed support 6
Since the cable does not move, the cable guide 4 attached to the rotating support 5 is loosely spread outward. When the cable guide 4 is attached right-handed, it moves in the same manner as when it is attached left-handed.

Cable guide 4 when rotating body 2 rotates
Is that one end attached to a fixed column 6 provided on the main body is fixed, and the other end attached to the pivot column 5 is
Move together with the movement of.

The rotating body 2 rotates right and left by the same angle. Since the cable 3 extends along the cable guide 4, whichever the rotating body 2 rotates, the cable 3 expands and contracts in the radial direction of the motor together with the cable guide 4 according to the rotating movement. Therefore,
The movement of the cable 3 when the rotating body 2 rotates is constant.

Further, in this embodiment, the cable guide is spirally mounted in the radial direction of the motor, but as another embodiment, the cable guide 4 may be spirally mounted in the longitudinal direction of the motor. With this configuration, the size of the cable guide in the radial direction can be reduced, and the side portion can be made more compact.

[0011]

According to the present invention, the movement of the cable moving following the rotation of the rotating body becomes constant by attaching the cable guide. This eliminates cable problems such as bending, rubbing, snagging, pulling, etc. as when the cable guide was not attached. Also, since the way of cable routing is decided,
No matter who works, the cable wiring is unified and the length of the cable is also determined, so that the cable is not too long or too short by the operator and waste is eliminated.
