As described above, the fixing block 14 is inserted between the guide part 11 and the metal block B while the side of the metal block B is fixed by using the third fixing part 40. Prevents flow in the left and right directions and fixes stably.

Subsequently, the first and second fixing bars 22 and 22 ′ are rotated in opposite directions with a force greater than that of the force acting between the magnet 222 and the first fixing bar 22 to separate the first and second fixing bars 22.

After the separated first and second fixing bars 22 and 22 'are positioned to be orthogonal to the metal blocks B, the first to fourth fixing bolts 23 to 26 are rotated in one direction to form metal blocks ( Fix the upper surface of B) stably.

As described above, the first to third fixing parts 20, 30, and 40 coupled to fix the metal block are simply formed by using a hexagon wrench so as not to interfere with the machining even during the machining of the metal block B. After loosening the hexagon wrench bolts fixing the first to fourth fixing bolts 23 to 26 and the second coupling part 30, the position is easily fixed again.

Next, the process of completing the metal block to the process is completed will be described.

When the machining operation is completed, the first fixing part 20 and the second fixing part are loosened by loosening the hexagon wrench bolts fixing the first to fourth fixing bolts 23 to 26 and the second coupling part 30 using the hexagon wrench. Separate (30).

At this time, the first and second fixing bars 22 and 22 ′ of the first fixing part 20 are rotated to overlap each other and are attracted to each other by an attractive force acting between the magnet 222 and the first fixing bar 22. Keep overlapping.

Subsequently, after removing the fixing block 14 inserted between the guide part 11 and the metal block B, the third fixing part 40 is separated.

As such, when all of the first to third fixing bars 20 to 40 are separated, the metal block B is moved from the holder 10 to a predetermined place and loaded.

Through the process as described above, the present invention can be fixed and detached stably to the holder by simply tightening or releasing the first to third fixing parts to improve the quality by precisely processing the body of the hydraulic breaker. Can be.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.

In the above embodiment, the third fixing part 40 has been described as being formed of a support bar 41 having a substantially 'b' shape, but the present invention is not necessarily limited thereto.

5 is an enlarged view illustrating main parts of a third fixing part of a main body jig device for a hydraulic breaker according to another exemplary embodiment of the present disclosure.

As shown in FIG. 3, the third fixing part 40 ′ is formed to correspond to the coupling groove 13 at the lower end of the support bar 43 and the support bar 43 having a substantially 'b' shape. It is provided with a support plate 45 for supporting the side of the metal block (B) by a bolt fastened through the coupling hole formed on the upper end of the coupling protrusion 44 and the support bar 43.

That is, according to the present invention, by fixing the support plate to the metal block by rotating the bolt in one direction, the metal block can be more stably fixed so that the metal block does not flow in the left and right directions.
