Description

[0001] JIG DEVICE AND DRILLING METHOD [0002]

The present invention relates to a jig device and a hole machining method, and more particularly to a jig device for fixing an object to be machined when a hole is formed in the object and a method for machining the hole.

When machining an object to be machined, the object to be machined is fixed to a jig and then machined using a machine tool such as a drill or a lathe. As to the jig for fixing the object to be processed in this way, various patents have been filed including the registered patent No. 10-1234272.

Particularly, in the conventional case, when a hole is formed in an object to be processed, a workpiece is fixed to the jig and only a machine tool (drill) is rotated to form a hole in the object.

However, in the case of forming the hole in this manner, there is a problem that the diameter deviation in the hole is severely generated if the depth of the hole to be processed is deepened.

Korean Patent No. 10-1234272

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hole machining method capable of machining a hole having a long length without a variation in diameter inside the hole and a jig device used at this time.

The jig device according to the present invention is for fixing the object to be processed during drilling of the object, comprising: a fixing part, one end of which is fastened and fixed, And a driving unit for transmitting a rotational force to the fixing unit so that the fixing unit, the auxiliary fixing unit and the object to be processed are rotated together .

According to the present invention, it is preferable that the fixing portion is slidably provided to the auxiliary fixing portion so that the distance between the fixing portion and the auxiliary fixing portion can be changed.

A hole machining method according to the present invention is a hole machining method for forming holes in an object to be machined by using a rotating cutting tool, characterized in that a hole is formed in the object to be machined while rotating the object and the cutting tool in opposite directions .

According to the present invention, a hole having a long length can be machined without a deviation in the diameter of the inside of the hole.

Fig. 2 is a view of the fixed portion and the driving portion shown in Fig. 1 in the direction of arrow a.
3 is a photograph of the fixing portion in Fig.
4 is a photograph of an object to be processed which is processed according to the present invention.

Hereinafter, a jig apparatus and a hole processing method according to preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a schematic configuration diagram of a jig apparatus according to an embodiment of the present invention. FIG. 2 is a view of the fixing unit and the driving unit shown in FIG. 1 in the direction of arrow a, Fig. 4 is a photograph of the object to be processed, which is processed according to the present invention. Fig.

1 to 4, the jig apparatus 100 according to the present embodiment includes a fixing portion 10, a auxiliary fixing portion 20, and a driving portion.

The fixing portion 10 is formed in a cylindrical shape and is inserted into the housing 40 so as to be rotatable. At this time, both end portions of the fixing portion 10 protrude outward with respect to the housing 40. A bearing or the like is provided between the housing 40 and the fixing portion 10 so that the fixing portion 10 can rotate inside the housing 40. [ The fixing part 10 is provided with three fastening bars 11 for fastening and fixing the object 1 to be processed. Each fastening bar 11 is radially disposed at the same angle, that is, 120 degrees apart from each other, and each fastening bar 11 is arranged so as to be linearly movable. Therefore, when one end of the object 1 is inserted between the three fastening bars 11 in a state in which the three fastening bars 11 are opened to each other and the three fastening bars 11 are narrowed, .

The auxiliary securing portion 20 is for securing and fixing the other end portion of the object 1. This auxiliary securing portion 20 is particularly necessary when the length of the object 1 is long. The auxiliary securing portion 20 is disposed so as to be spaced apart from the fixed portion 10 in the longitudinal direction of the object 1. The auxiliary securing portion 20 is formed in a cylindrical shape and is rotatably installed in the auxiliary housing 50. The auxiliary fastening portion 20 is also provided with three fastening bars 21 for fastening and fastening the object 1 to be processed. At this time, the structure and operation principle of the three fastening bars 21 are the same as those of the fastening bar 11 described in the fixing part 10.

A rail 60 is provided between the housing 40 and the auxiliary housing 50 and at least one of the housing 40 and the auxiliary housing 50 is installed to be movable along the rail 60. Therefore, the interval between the fixing portion 10 and the auxiliary fixing portion 20 can be changed according to the length of the object 1 to be processed.

The driving unit is for rotating an object to be processed. In this embodiment, the driving unit is composed of a motor 31 and a driving belt 32. The motor 31 is disposed on the upper side of the housing 40. The drive belt 32 is installed so as to enclose the drive shaft of the motor 31 and the rear side end portion of the fixed portion 10. When the motor 31 is driven, the driving force of the motor is transmitted to the fixed portion 10 through the driving belt 32. Then, the fixing part 10, the object to be fixed 1 fixed to the fixing part, and the auxiliary fixing part 20 coupled to the other end of the object to be processed rotate together.

Hereinafter, a method of forming holes in an object to be processed using the jig apparatus 100 configured as described above will be described.

First, one end of the object 1 is inserted into the fixing part 10 and fixed. Thereafter, the distance between the auxiliary securing portion 20 and the securing portion 10 is adjusted to the length of the object to be processed, and the other end of the object 1 is fitted and fixed to the auxiliary securing portion 20. [ Thereafter, a hole is formed in the object 1 by using a cutting tool that drives the driving portion to rotate the fixed portion, the object to be processed, and the auxiliary fixing portion and forms a hole like a drill in this state. At this time, it is important that the workpiece is rotated in the direction opposite to the direction of rotation of the cutting tool.

When holes are formed in the object by the above-described method, even if the depth of the hole is deepened, the diameter deviation within the hole is much smaller than the conventional one (that is, the hole is formed by rotating only the cutting tool while fixing the object to be processed) do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation in the embodiment in which said invention is directed. It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
