1 to 9, the jig 100 for processing the hole inclined in equal division in the base material 20 of the present invention is provided with a fixed chuck 11 that rotates by receiving a rotational force on one side, the other side in the front and rear directions The inclined hole 22 is machined through a processing device 10 equipped with a drill for drilling holes while traveling.

Here, the base material 20 having the inclination angle to the base material 20 through the processing device 10 and the jig 100 for mounting the base material 20 to the processing device 10 for processing the plurality of inclined holes 22 by equal division are installed.

First, the jig 100 is bitten by the fixed chuck 11 of the processing apparatus 10 to rotate in conjunction with the fixed chuck 11 of the processing apparatus.

The jig 100 forms a rotation plane 112 having a vertical angle formed by the fixing protrusion 116 which is bitten by the fixing chuck 11 on one side so as to eccentrically protrude from the lower side.

The other side of the jig 100 opposite the rotation plane 112 forms an inclined inclined surface 113 having an inclined angle so that the base material 20 is in close contact, and the inclined surface 113 is an inclination angle of the inclined hole 22 to be processed in the base material 20 through a processing device. Determine.

That is, the settling surface 113 has a slope. An inclination angle is formed such that the thickness between the inclined slope 113 and the rotation plane 112 is gradually thinned from the top to the bottom.

And, in the center of the inclined slope 113 of the jig 100 is formed a support insertion hole 114 having an angle at a right angle with the inclined slope 113.

That is, the support insertion hole 114 has an angle inclined downward in the direction of the settling slope 113 from the rotation plane 112.

In addition, the communication inclined surface 113 of the jig 100 to form a horizontal communication hole 119, the communication hole is formed in the groove shape in the lower portion of the support insertion hole 114.

Here, the fixing plane 116 is formed to protrude on the rotation plane 112 of the jig 100 to be bitten by the fixed chuck 11 of the processing apparatus 10, and the fixing projection 116 is formed at a position eccentrically downward from the rotation plane 112 of the jig 100. The fixing protrusion 116 and the communication hole 119 are formed at the same position in a virtual straight line on the rotation plane 112 and the inclined plane 113 of the jig 100.

The reason for this is that the fixing protrusion 116 of the jig 100 and the communication hole 119 and the drill 13 which are bitten by the fixing chuck 11 are arranged at the same position in a virtual straight line so that the rotation centers of the jig 100 eccentrically rotating at the fixing chuck 11 coincide with each other. Be sure to

In addition, the weight balance of the eccentric upper and lower parts of the jig 100 based on the fixing projection 116 bitten to the fixed chuck 11 by mounting a weight 120 on the lower side of the fixing projection 116 side of the rotation plane 112 to enable the round rotation of the jig 100. To match.

The base material 20 coupled to the jig 100 configured as described above forms a support hole 21 in the center to communicate with the support insertion hole 114, and then fixes the base material 20 to the jig 100 through the support bar 130 to be described later.

Then, a plurality of position grooves 23 are formed at equal intervals around the front surface of the base material 20.

That is, the front surface of the base material 20 refers to the surface in close contact with the inclined slope 113 of the jig 100, the front surface of the base material 20 is in close contact with the inclined slope 113 of the jig 100, wherein the position groove 23 of any one of the position groove 23 Position projection 118 of the jig 100 is coupled to prevent the idling of the jig 100 and the base material 20.

In addition, the support bar 130 is formed in the shape of a rod having a cylindrical shape with a length is formed on one side of the support fixing body 131 is formed with a screw thread on the outer circumference and the flange 133 is formed on the other side.

The support bar 130 is coupled through the support insertion hole 114 of the jig 100 so that the flange 133 of the support bar 130 is locked to the inlet end of the support insertion hole 114, and the support fixing body 131 of the support bar 130 passes through the support hole 21 of the base material 20. The jig 100 and the base 20 are integrally fixed through the fixing member 131.

In addition, a communication hole 119 is formed on the inclined surface 113 of the jig 100, and the communication hole 119 is positioned below the support insertion hole 114, and is located at a position corresponding to the fixing protrusion 116 formed on the rotation plane 112 in a straight line. It is formed and located in line with the drill of the processing apparatus 10.

As a result, when the inclined hole 22 is processed in the base metal 20 through the drill 13, the drill penetrates through the base material 20 to enter the communication hole 119, thereby enabling the complete through processing of the inclined hole 22 processed in the base material 20.

Using the jig 100 configured as described above, the method of processing the inclined hole 22 into the base material 20 by equal division is as follows.

In the first step, the jig 100 is eccentrically coupled to the fixed chuck 11 of the processing apparatus 10 on which the drill 13 is mounted.

That is, the fixing protrusion 116 of the jig 100 is coupled to the fixed chuck 11 so as to eccentrically couple the jig 100 based on the fixing protrusion 116 to be fixed to the fixed chuck 11.

Thereafter, in the second step, the weight 120 is mounted on the jig 100 to balance the upper and lower weights of the jig 100 based on the fixed chuck 11. The weight 120 forms a weight fixing hole 117 in the lower rotation plane 112 formed on one side of the jig 100 to couple the weight weight 120 to the weight fixing hole 117.

The weight 120 is mounted on the lower portion of the jig 100 that is relatively lighter than the upper portion of the jig 100 based on the fixing protrusion 116 of the jig 100 to match the weight balance of the top and the bottom of the jig 100.

The fixing protrusion 116 may be the center of gravity of the jig 100 combined with the base material 10 so that the fixing protrusion 116 can be rotated in a circle without the flow or vibration during the rotation of the jig 100 and the base material 20 through the fixing chuck 11.

After coupling the weight 120 to the jig 100 as described above, a third step process of obliquely coupling the base material 20 to the inclined slope 113 formed on one side of the jig 100.

That is, in the third step, the inclined slope 113 of the jig 100 is formed to be inclined to couple the base material 20 to be inclined, but the position grooves of any one of the plurality of position grooves 23 formed at equal intervals around the front surface of the base material 20. 23 is combined with the position projection 118 formed on the inclined slope 113 to prevent the jig 100 and the base material 20 idle.

Next, the support bar 130 is coupled through the support insertion hole 114 of the jig 100 so that the flange 133 of the support bar 130 is locked to the inlet end of the support insertion hole 114, and the support fixture 131 of the support bar 130 is the support hole 21 of the base material 20. It penetrates through to fix the jig 100 and the base 20 through the fixing member 131 integrally.

Thereafter, the fourth step and the fifth step undergo a step of rotating the base material 20 through the processing apparatus 10 and at the same time forming the inclined hole 22 which is an inclined hole in the base material 20 through the drill 13 of the processing apparatus 10.

That is, when the base material 20 rotates through the jig 100, the drill 13 located on the opposite side of the jig 100 in the processing apparatus 10 is moved to the base material 20 to form the inclined hole 22 through the drill 13 in the rotating base material 20.

At this time, the inclined hole 22 processed in the base material 20 communicates with the communication hole 119 of the jig 100.

As described above, after the first inclined hole 22 is formed in the base material 20, the base material 20 is separated from the jig 100.

To this end, the fixing member 131 fastened to the support fixing body 131 of the support bar 130 is released and separated. Then, the support bar 130 is pulled out from the jig 100 in the flange 133 direction of the support bar 130 to separate the base material 20 from the jig.

Next, in the seventh step, the base metal 20 can be recombined with the jig 100 so that the position where the inclined hole 22 of the next order is processed in the base metal 20 coincides in a straight line with the drill 13.

That is, when forming the inclined hole 22 of the next step in the seventh step, the position groove 23 of the base material 20 is separated from the position protrusion 118 of the jig 100, and then the position grooves 23 of the other places are combined to drill the inclined hole 22 of the next step. Make sure that the position coincides with the drill 13 in a virtual straight line.

In the eighth step, the base metal 20 is rotated through the processing apparatus 10 to form the inclined holes 22 to be processed in the next order using the drill 13.

In particular, the ninth step is performed by repeatedly performing the seventh and eighth steps as described above to process a plurality of inclined holes 22 in the base material 20 by equal division.

As such, while allowing the base material 20 to be inclined to the jig 100 so as to form an inclined hole in the base material 20 by drilling the hole 13 of the drill 13 arranged horizontally through the jig 100 for mounting the base material 20 to the processing apparatus 10, By rotating the base material 20 at a predetermined angle in the jig 100, the hole positions to be processed in the next order are matched to the machining positions of the drill 13, thereby improving processing convenience and reducing processing costs by reducing processing time.
