Directly below the rotary rod 22, the pressing shaft 27, which is provided with two eccentric pressing holes 28 at the side ends, is rotatably installed on the first mounting table 21, and will be described below directly below the pressing shaft 27. Push bar 26 for pressing the upper end of the clamp 60 is installed to be elevated along the guide groove (30). In addition, an alignment guide 31 for guiding the verticality of the fixing stick 64 is installed at the lower portion of the first mounting table 21 through bolts. Thus, the components corresponding to the frame of the alignment jig 20 are combined as shown in FIG. 3.

4 is an exploded perspective view of the conformal splitter 40 and the clamp 60 according to the present invention, and FIG. 5 is a combined perspective view of the alignment jig 20 according to the present invention. As shown in FIG. 4, the third driven gear 55 is rotatably mounted to the rear of the second mounting table 56, and the second driven gear 54 is formed on the outer circumferential surface of the third driven gear 55. 60 is mounted, and the second driven gear 54 and the third driven gear 55 are mounted to engage with each other.

Further, the first driven gear 53 is rotatably mounted in front of the clamp 60, and the second driving gear 52 is mounted in front of the first driven gear 53. Therefore, due to the engagement of the driven gears 53, 54, 55 by one operation of the second drive gear 52, a plurality of fixed parts mounted on the collet 62 of the clamp 60 are eventually fixed. Sticks 64 are rotated at an angle.

Hereinafter, a detailed configuration of the conformal splitter 40 for operating the second driving gear 52 will be described with reference to FIG. 6. 6 is an exploded perspective view of the conformal splitter 40 according to the present invention, in which a fixture 44 is fixed to the front lower portion of the second mounting table 56 through a bolt. The bearing 45 is mounted on the outer circumferential surface of the fixture 44, which makes the rotational motion of the conformal splitter 40 flexible. On the other hand, the stopper 46, which is a characteristic configuration of the present invention, is fixed to the front of the outer peripheral surface of the fastener 44. The function of the stopper 46 will be described later with reference to FIG. 7.

As shown in FIG. 6, a housing 41 is extrapolated to an outer circumferential surface of the fixture 44, and an uppermost portion of the housing 41 is formed with an isometric cut portion 42 cut in a predetermined width, and directly under the isometric cut portion 42. In the room, a shoulder groove 43 for pulling the shoulder hole 49 formed in the upper first driving gear 48 is formed, and the position thereof is located directly below the imaginary bisector of the conformal incision 42.

In addition, the central shaft 50 formed integrally with the lower first driving gear 47 is inserted into the housing 41 and penetrates the fixing tool 44, and is installed on the upper portion of the second mounting table 56. It is configured to interlock with the two drive gear 52 and the bolt. That is, the second driving gear 52 is operated by the lower first driving gear 47 and always works together.

In addition, an upper first driving gear 48 having a shoulder opening 49 protruding from an outer circumferential surface thereof is installed directly above the lower first driving gear 47, and an upper portion of the upper first driving gear 48. As the spring 51 is mounted, a stable return at the temporary rise of the upper first driving gear 48 and a stable position after the return are possible.

The temporary rise of the upper first driving gear 48 occurs when the housing 41 is rotated in a counterclockwise direction as shown in FIG. 7A, and the solid groove 43 of the housing 41 is formed of the upper agent. The first driving gear 48 is in a state of being caught by the shoulder port 49, and the upper first driving gear 48 and the lower first driving gear 47 engaged therewith also generate a rotational force in a counterclockwise direction.

However, at this time, the lower first driving gear 47 is configured to interlock with the second driving gear 52, and the second driving gear 52 is engaged with the first driven gear 53, and the first driven gear Considering that the gear 53 is meshed with the second and third driven gears 54 and 55, the lower first driving gear 47 is not rotated without a strong external force because the lower first driving gear 47 is under heavy load. .

Further, considering that the shape of the teeth of the upper and lower first driving gears 47 and 48 is a right triangle as shown in FIG. 6 and the enlarged ellipse in FIG. 7 (a), the upper first driving gear 48 is The lower first driving gear 47 cannot be rotated, but rather is temporarily displaced from the engaged state with the lower first driving gear 47 while being rotated counterclockwise to rise upward.

As described above, the temporarily raised upper first drive gear 48 repeatedly moves up and down by being stably lowered by the elasticity of the first spring 51, and then isometric 42 of the housing 41. ) Is caught by the stopper 46 and the counterclockwise motion of the upper first driving gear 48 and the housing 41 is stopped as shown in FIG.

When the housing 41 stopped by the stopper 46 is rotated clockwise again as shown in FIG. 7B, the shoulder groove 43 of the housing 41 is connected to the shoulder hole of the upper first driving gear 48. 49), the upper first driving gear 48 and the lower first driving gear 47 engaged with each other also generate a rotational force in a clockwise direction, and the half of the housing 41 as shown in FIG. Unlike the clockwise rotation, as the upper and lower first driving gears 47 and 48 rotate together to rotate, the first driven gear 53 and the second and third driven gears 54 that are driven with the driving force are engaged. 55 are rotated together in a clockwise direction, and eventually, a plurality of fixing sticks 64 mounted on the collet 62 of the clamp 60 are simultaneously rotated at a predetermined angle.

As described above, the angle at which the plurality of fixing sticks 64 are rotated is determined by the cutting width of the isometric cut-out portion 42 of the housing 41 and the number of teeth of the upper and lower first driving gears 47 and 48. The combination can be set at various angles.

FIG. 8 is a cross-sectional view for explaining the chucking function of the fixing stick 64 in the collet 62 of the clamp 60. The clamp 60 is shown in FIGS. A second driven gear 54 is formed on the outer circumferential surface, the second spring 61 is inserted into the clamp 60 and exposed to the collet 62 at the same time, and the collet 62 has a tip 3 As a shape divided into pieces, the second spring 61 is formed between the head 63 after being inserted into the clamp 60.

The fixing stick 64 to which the gemstone 70 is adhered is mounted while being collected by the collet 62 in which the insertion part 65 is divided, as shown in FIG. 8B, and the head 63 of the clamp 60 is mounted. The push bar 26 is located at the upper part, and a pressurization hole 28 eccentrically installed at the side end of the pressing shaft 27 is installed directly above the push bar 26 to push the push bar 26 downward by eccentric rotation. To pressurize.

That is, as shown in FIG. 8A, when the lever 29 of the pressure shaft 27 is rotated, the eccentric pressure port 28 rotates eccentrically and presses the push bar 26 as shown in FIG. 8B. As a result, the collet 62 in the interpolated state protrudes below the clamp 60 as shown in FIG. 8 (b), and the insertion part 65 of the fixing stick 64 is inserted into the collet 62. Next, when the lever 29 is returned to its original state, the second spring 61 is returned to its original state, and the collet 62 is inserted into the clamp 60, and eventually the plurality of fixing sticks 64 can be chucked simultaneously. .
