DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling device for a traveling body capable of traveling on a curved line.

[0002]

Conventionally, as a device for converting a rotary motion into a linear motion, there is a device using a screw shaft and a nut externally mounted on the screw shaft. This is a device in which the screw shaft is rotated while the rotation of the nut is stopped, and the nut is moved linearly. However, in the above-mentioned conventional apparatus, since the steel rod is used for the screw shaft, the nut can travel only on a straight line. Therefore, work is limited to work on a straight line.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is capable of traveling along a curved line and can be used for various operations on the curved line. It is an object to provide a body running device. That is, the present invention provides a flexible screw having flexibility and magnetism provided with a helical protrusion on the outer peripheral surface of a flexible rod, and a guide member having a magnetic force for attracting and holding the flexible screw at a predetermined position. A means for rotating the flexible screw, and a traveling body having a groove that meshes with the helical projection of the flexible screw, and a traveling body attached to the guide member so as to be able to travel in a state where the rotation is stopped, is there.

[0004]

An embodiment of the present invention will be described below with reference to the drawings. <B> Flexible screw The flexible screw 1 is, as shown in FIGS.
A helical projection 12 is formed on the outer peripheral surface of a flexible rod 11. The flexible rod 11 is a rod having flexibility and magnetism. For example, the flexible rod 11 is formed by spirally winding a steel wire or the like at a close interval around a core material formed of a flexible member such as reinforced rubber. I do. The spiral projection 12 is formed, for example, by winding a wire made of a steel material or a resin material (polyolefin, polyether, etc.) around the outer peripheral surface of the flexible rod 11 at a predetermined pitch in a spiral manner. Note that the outer peripheral surface of the flexible rod 11 may be covered with the above resin material.

<B> Guide Member The guide member 2 is a strip-shaped member as shown in FIGS. 1 and 2, and is formed of a metal or the like having a low friction coefficient and abrasion resistance. A receiving groove 21 for accommodating the lower half or a part of the flexible screw 1 is provided on the upper surface of the guide member 2.
Is provided over the entire length of the guide member 2. Receiving groove 2
The shape of 1 can adopt an arc, a V-shape, a rectangle, or the like. Also,
In the lower part of the receiving groove 21 or in the vicinity of the peripheral part, magnets 22 are embedded at appropriate intervals over the entire length of the guide member 2. The magnet 22 has a magnetic force that attracts and holds the flexible screw 1, and that can rotate the flexible screw 1 and does not separate from the receiving groove 21. Rolling grooves 23 for fitting rolling balls, which will be described later, are formed on both side surfaces of the guide member 2 over the entire length of the guide member 2.

<C> Laying of Flexible Screw The flexible screw 1 used in the present invention has flexibility and can be bent into an arbitrary shape. Therefore, as shown in FIG. 1, the guide member 2 can be laid along a straight line or an arbitrary curved line, and the flexible screw 1 can be arranged according to the shape of the receiving groove 21.

<4> Traveling body The traveling body 3 is a spiral projection 1 of the flexible screw 1.
The guide member 2 has a groove that meshes with the guide member 2 and is movably attached to the guide member 2. For example, as shown in FIGS. 2 and 3, support plates 3 are provided on both sides of a traveling table 31 having a T-shaped cross section or the like.
It is conceivable that the two are mounted and formed in a gate shape. On the lower surface of the traveling table 31, as shown in FIG.
An engaging groove 33 that engages with 2 is formed. The cross section of the engagement groove 33 is formed to be slightly larger than the cross section of the spiral projection 12 so that there is a play in the engagement between the two and the running body 3 can smoothly pass through the curved portion of the flexible screw 1. In addition, a screw hole 34 for screwing various working devices or the like may be formed on the upper surface of the traveling table 31. As shown in FIG. 2, the support plate 32 is attached to the traveling table 31 with bolts 35. A rolling ball 36 screwed into the rolling groove 23 of the guide member 2 is rotatable inside the lower end. It is attached to. Also, on the inside of both support plates 32,
A support ball 37 for supporting the side surface of the guide member 2 is attached to prevent the running body 3 from moving right and left.

<E> Rotary Driving Device As a rotary driving device of the flexible screw 1, for example, as shown in FIG. 5, a grip fitting 4 is attached to one end of the flexible screw 1, and a gear 41 is fixed to this, and the gear 41 is fixed. A configuration in which the motor 41 and the motor 42 can be linked to each other can be considered. On the other hand, flexible screw 1
Is supported by a bearing or the like. Next, when this apparatus is operated, the motor 42 is driven to rotate the flexible screw 1. The traveling body 3 has the engagement groove 33 meshed with the flexible screw 1 and the guide member 2
Since it is mounted in a state where the rotation is stopped, it can be moved along the guide member 2.

[0009]

Since the present invention has been described above, the following effects can be obtained. <A> In the present invention, since the flexible screw having flexibility is used, the traveling body can travel on an arbitrary curved line. Therefore, various operations on the curved line can be performed.

<B> Since the device of the present invention has a simple structure, it has few components, can be easily disassembled, and is lightweight. Therefore, transportation, storage, cleaning, and the like of the device can be easily performed.
