A pair of Y-axis grooves 188 is formed on the bottom of the Y-axis base plate 180, and a pair of Y-axis rails 190 protrude from the upper surface of the Y-axis transfer plate 184. In addition, the pair of Y-axis rails 190 are slidably coupled to the pair of Y-axis grooves 188.

Therefore, when the Y-axis adjusting screw 186 is rotated, the Y-axis feed plate 184 is movable because the Y-axis rail 190 is slidably coupled to the Y-axis groove 188.

One end of the Y-axis adjustment screw 186 is inserted into the Y-axis support bar 182, and the other end is screwed into the Y-axis screw hole (h2) formed on the side of the Y-axis transfer plate 184.

In addition, the Y-axis adjusting screw 186 is provided with a third stopper 192 to limit the forward movement of the Y-axis, and the fourth stopper 194 is provided to limit the reverse movement.

At this time, the Y-axis support bar 182 is fixed by a pair of connecting shafts (194a, 194b) protruding from both sides of the side of the Y-axis transfer plate 184, respectively. In addition, the Y-axis support bar 182 is formed with a semi-circular groove 193 is inserted into the Y-axis adjustment screw 186.

Therefore, when the Y-axis adjustment screw 186 is rotated forward,

Since the third stopper 192 is in contact with the outer surface of the Y-axis support bar 182,

When the Y-axis feed plate 184 is movable in the positive direction of the Y-axis, and the Y-axis adjustment screw 186 reversely rotated, the fourth stopper 194 is on the inner surface of the Y-axis support bar 182 As it comes in contact, the Y-axis feed plate 184 is movable in the reverse direction of the Y-axis.

As a result, the Y-axis adjusting screw 186 is rotated forward or reverse, the Y-axis transfer plate 184 can be properly moved along the Y-axis direction.

As described above, the bite assembly 107 of the head portion 9 can be moved to the single ball position by appropriately moving the X-axis portion 99 and the Y-axis portion 104.

When the head portion 9 reaches the upper predetermined position of the single ball B, the surface of the single ball can be processed by lowering the bite assembly 107 by the Z-axis portion 101.

The Z-axis portion 101 is a Z-axis base plate 196 mounted on the Y-axis transfer plate 184,

The Z-axis servomotor assembly 200 includes a cylinder 206 for generating power, and a piston 208 that is retractably provided in the cylinder 206 and connected to the Z-axis transfer plate 198.

Therefore, when the piston 208 advances, the Z-axis transfer plate 198 descends, and when the piston 208 contracts, the Z-axis transfer plate 198 rises.

In this way, the head portion 9 is moved to the machining position by the X-axis portion 99 and the Y-axis portion 104, and then moved up and down by the Z-axis portion 101, the bite assembly 107 is a single ball (B) ) May be in contact with the surface.

In the θ-axis portion having such a structure, the submotor 212 is controlled by a signal from the controller 15, and the rotation shaft 213 of the submotor 212 is rotatable by a predetermined angle.

Therefore, when the sub-motor 212 is driven, the bite assembly 107 for processing the single ball (B) by rotating the θ-axis rotation bar 214 by a predetermined angle with respect to the surface of the single ball (B) It can process by rotating by a fixed angle.

At this time, the bottom surface of the θ-axis rotation bar 214 is formed a curved surface (S) having a constant curvature. The bite assembly 107 is coupled to the curved surface S. FIG.

In addition, by displaying a scale on the curved surface S, the inclination angle of the bite assembly 107 may be recognized.

Thus, the bite assembly 107 has an inclined shape, such that the upper portion of the bite assembly 107 is disposed outside a predetermined distance on the rotation axis, and the lower processing blade 146 is disposed on the rotation axis.

In this state, when the sub-motor 212 is driven, the upper portion of the bite assembly 107 is moved along the circular trajectory by the rotation of the θ-axis rotation bar 214, the cutting edge 146 is a single The contact state is maintained in the ball (B).

As a result, as the sub-motor 212 rotates at an angle, the bite assembly 107 rotates together along the surface of the single ball (B) to form various curved shapes such as concentric circles on the surface of the single ball (B). It is possible to form the groove (W) having a.

On the other hand, the bite assembly 107 is coupled to the drive unit 105, the drive unit 105 is detachable by the chuck 111 and the chuck 111 capable of fixing the cutting edge 146 of various standards, and the chuck 111 It is coupled by the processing includes a machining blade 146 for processing in contact with the surface of the single ball (B).

In the bite assembly having this structure, the drive unit 105 includes a motor. The processing blade 146 is connected to this motor.

Therefore, when the motor is driven, the processing blade 146 is rotated to form the groove W on the surface of the single ball (B).

The chuck 111 is separated into two

parts

109 and 113 and has a structure in which the chuck 111 is integrally coupled to each other by a coupling pin 147.

Therefore, when the machining blade 146 is replaced with another machining blade, the coupling pin 147 may be released, and the two cutting

units

109 and 113 of the chuck 111 may be replaced with other machining blades.

In this way, an appropriate processing blade 146 can be selected and used in accordance with the depth width and the like of the groove W formed in the single ball B.

In addition, the processing blade 145 is a material that can form a groove (f) on the surface of the single ball (B) during rotation, preferably a diamond material.

Therefore, when the bite assembly 107 is rotated by the drive unit 102, the machining blade 145 is in contact with the surface of the single ball (B) to form the groove (W).

As a result, the head portion 9 forms a pattern of various shapes on the surface of the single ball (B) by appropriately adjusting parameters such as the distance between the machining blade 145 and the single ball (B), rotation angle, rotation speed, etc. can do.

Meanwhile, as illustrated in FIG. 1, the single ball B may be supplied to the processing position by the single

ball supply units

When the second transfer plate 37 is moved secondarily, the tip 135 of the first spindle 75 may be in frictional contact with the surface of the single ball (B).

In addition, the second chuck C2 may also be moved to the machining position. At this time, the second chuck C2 is moved to the machining position by the third servo motor assembly 43, and since the second chuck C2 is moved by the same process as the first chuck, a detailed description of the process of moving to the machining position is omitted. .

After the second chuck C2 reaches the machining position, the cylinder is driven to move the third transfer plate 39 secondarily.

When the third transfer plate 39 is moved secondarily, the front end portion 137 of the second spindle 81 may be in frictional contact with the other surface of the single ball (B).

Accordingly, the single ball B may be supported by the first and

second spindles

75 and 81, and the holder 130 may be returned to its original position by removing the suction force on the single ball B. FIG.

In this state, since the third motor assembly 95 of the second chuck C2 is driven to rotate the second spindles 81, the single ball B is rotatable. At this time, the first spins 75 of the first chuck C1 are in an idling state.

When the X-axis adjusting screw 166 is rotated in reverse, the second stopper 174 is in contact with the inner surface of the X-axis support bar 162, the X-axis feed plate 164 in the opposite direction of the X-axis It is movable.

Therefore, the X-axis adjusting screw 166 is rotated forward or reverse, the X-axis transfer plate 164 can be properly moved along the X-axis direction.

And the head part 9 can be moved to a machining position by moving the Y-axis part 104 to a Y-axis direction suitably.

In the Y axis portion 104, when the Y axis adjustment screw 166 is rotated forward,

Since the third stopper 192 is in contact with the outer surface of the Y-axis support bar 182, the Y-axis feed plate 184 is movable in the positive direction of the Y-axis,

When the Y-axis adjusting screw 166 is rotated in reverse, the fourth stopper 194 comes into contact with the inner surface of the Y-axis support bar 182, so that the Y-axis feed plate 184 is in the opposite direction of the Y-axis. It is movable.

As a result, the Y-axis adjusting screw 166 is rotated forward or reverse, the Y-axis transfer plate 184 can be properly moved along the Y-axis direction.

When the head portion 9 reaches the upper predetermined position of the single ball B, the surface of the single ball B can be processed by lowering the bite assembly 107 by the Z-axis portion 101.

That is, when the Z-axis cylinder assembly 200 is driven, the Z-axis transfer plate 166 may be lowered along the Z-axis direction by the piston 208 is lowered.

In this manner, the head portion 9 is moved to the machining position by the X-axis portion 99 and the Y-axis portion 104, and then moved up and down by the Z-axis portion 101 so that the bite assembly 107 is a single ball. It may contact the surface of (B).

In this state, when the motor of the drive part 105 drives, the process blade 146 rotates and the groove | channel W is formed in the surface of the single ball B. As shown in FIG.

When the working blade 146 starts to form the groove W, the first and

second spindles

75 and 81 of the first and second chuck portions C1 and C2 supporting the single ball B are formed. Will rotate.

Therefore, the single blade (B) also rotates so that the working blade 146 forms the groove (W) along the circumferential direction along the surface of the single ball (B).

When the sub-motor 212 of the θ-axis part 100 is driven while the processing blade 146 forms the groove W, the θ-axis rotation bar 214 rotates.

As the sub-motor 212 rotates at a predetermined angle, the bite assembly 107 rotates along the surface of the single ball (B) to have a groove having various curved shapes such as concentric circles on the surface of the single ball (B). (W) can be formed.

That is, since the processing blade 146 forms a linear groove W in the circumferential direction on the surface of the single ball B, and also forms a trajectory in the lateral direction by driving the θ axis part 100. The groove W may be formed not only in a straight shape but also in a curved shape on the surface of the single ball B. FIG.

In this way, the processing blade 145 of the bite assembly 107 can form grooves W of various shapes by contacting the outer circumferential surface of the single ball B at various angles.
