[0001] PALLET TABLE APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet table apparatus, and more particularly, to a pallet table apparatus capable of reducing a layout and reducing a rotational locus of a rotatable board.

In general, the machining center processes the workpiece. The machining center is provided with a rotating disk, and pallet table devices are installed on both sides of the rotating disk. The pallet of one pallet table device is loaded with machining material and then put into the machining center. The remaining pallet table devices stand outside the machining center. As the rotary disk is rotated, the pallet table device is rotated one by one and inserted into the machining center. The pallet is provided with a fixture to fix the workpiece. The fixture is immovably fixed to the workpiece as it is driven by the fluid.

On the upper side of the rotating shaft, a fluid supply device is provided so as to supply fluid to the jig portion of the pallet. The fluid supply device is installed so as to be movable up and down. The fluid supply device supplies fluid to the jig.

However, in the conventional pallet table apparatus, since the fluid supply device is provided on the upper side of the rotating plate, the volume of the machining center becomes large, and the structure of the machining center becomes complicated. Further, when the machining center is installed, the layout (installation space) is increased, and the rotational locus is increased by the fluid supply device and the hydraulic piping when the rotating disk is rotated.

Therefore, there is a need to improve this.

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Laid-Open Publication No. 2004-0046405 (published on May 05, 2004, entitled "Multi-palette magazine device capable of public use").

SUMMARY OF THE INVENTION It is an object of the present invention to provide a pallet table device capable of reducing the layout of equipment and reducing the rotational trajectory of the turntable.

A pallet table apparatus according to the present invention includes: a housing installed on both sides of a rotating frame; A rotating part rotatably installed inside the housing; A driving unit connected to the rotation unit to rotate the rotation unit; A table rotatably installed on the upper side of the rotation unit; A cylinder disposed between the housing and the rotary unit and lifting the rotary unit and the table by fluid; A pallet portion mounted above the table and having a fixture portion for fixing a workpiece; And a fluid supply line connected to the rotary part, the table, the pallet part, and the fixture part, and the fixture part supplies fluid to the fixture part so as to fix the workpiece.

A first cylinder installed to surround the rotating portion and having a flange portion protruding outward; And a hydraulic chamber provided so as to surround the first cylinder and in which the flange portion is received, a first hydraulic chamber is formed on the upper side of the flange portion, and a second hydraulic chamber is formed on the lower side of the flange portion. Two cylinders may be included.

When the table is lowered on the lower side of the table, the upper index gear part may be formed to mate with the lower index gear part.

Wherein the rotating portion is disposed on the inner side of the cylinder portion, and the table is disposed on the upper side; And an outer shaft disposed to surround the inner shaft and rotated together with the rotating portion.

A plurality of ring-shaped ribs are formed on the outer surface of the inner shaft. A ring-shaped rib is inserted into the inner surface of the outer shaft, and a flow groove can be formed to allow the fluid to pass therethrough.

The fluid supply line includes a first supply line formed in the housing; A second supply line formed in the rotating portion to be connected to the flow groove portion; A third supply line formed in the cylinder portion to be connected to the flow groove portion; A fourth supply line formed on the table to be connected to the third supply line; And a fifth supply line formed in the pallet portion to be connected to the fourth supply line and the fixture portion.

The driving unit includes: a ring gear coupled to the periphery of the rotation unit and having a gear part formed on an outer side; A reduction gear module engaged with the ring gear; And a motor unit for rotating the reduction gear module.

The chip can be discharged downward on the upper side of the table.

According to the present invention, since the fluid supply line is connected to the rotary part, the table, the pallet part and the fixture part, it is not necessary to provide a fluid supply device separately on the upper side of the pallet part. Therefore, the structure of the rotary shaft is simplified, and the volume of the rotary shaft is reduced. Further, since the rotation locus of the rotating disc is reduced, the layout of the machining center can be reduced.

Further, according to the present invention, when the table is lifted by the cylinder portion, the table can be rotated together with the cylinder portion and the outer shaft as the upper index gear portion is separated from the lower index gear portion. Thus, the workpiece can be rotated to the correct machining position.

Further, according to the present invention, when the table is lowered by the cylinder portion, the upper index gear portion is engaged with the lower index gear portion. Therefore, the table is constrained not to be rotated during machining of the workpiece.

FIG. 1 is a perspective view showing a machining center in which a pallet table apparatus according to an embodiment of the present invention is installed, FIG. 2 is a perspective view illustrating a pallet table apparatus according to an embodiment of the present invention, FIG. FIG. 4 is an exploded perspective view illustrating a pallet table apparatus according to an embodiment of the present invention, and FIG. 5 is a perspective view of a pallet table apparatus according to an embodiment of the present invention. 6 is a cross-sectional view illustrating a pallet table apparatus according to an embodiment of the present invention.

1 to 6, a pallet table apparatus according to an embodiment of the present invention includes a housing 110, a rotation unit 120, a driving unit 130, a table 140, a cylinder unit 150, a pallet unit 160 and a fluid supply line 170.

The housing 110 is installed on both sides of the rotating frame 13 of the rotating disk 10. [ As the rotary frame 13 is rotated, one pallet table device 100 is introduced into the machining center (not shown), and the other pallet table device 100 is waiting outside the machining center.

The machining center is provided with a machining portion 20, and the machining portion 20 is provided with a machining tool holder 23. A processing tool (not shown) is coupled to the processing tool holder 23. As the machining portion 20 is driven, the machining tool is rotated to machine the machining material. The rotation axis of the processing tool is formed in parallel.

The rotation unit 120 is rotatably installed inside the housing 110. The rotating portion 120 includes an inner shaft 121 and an outer shaft 125. [

The inner shaft 121 is disposed on the inner side of the cylinder portion 150, and the table 140 is disposed on the upper side. The inner shaft 121 is installed in the housing 110 so as not to be rotated.

The outer shaft 125 is disposed so as to surround the inner shaft 121 and is rotated together with the rotating portion 120. As the outer shaft 125 rotates, the table 140 rotates together.

A plurality of ring-shaped ribs 122 are formed on the outer surface of the inner shaft 121. A ring-shaped rib 122 is inserted into the inner surface of the outer shaft 125, 126 are formed. The fluid in the second feed line 172 of the inner shaft 121 is connected to the third feed line 173 of the cylinder section 150 through the flow groove 126. The fluid in the second supply line 172 of the inner shaft 121 flows into the third supply line 173 of the cylinder portion 150 through the flow groove portion 126. [

The driving unit 130 is connected to the rotation unit 120 to rotate the rotation unit 120. The drive unit 130 includes a ring gear 131 that is coupled to the periphery of the rotation unit 120 and has a gear portion formed on the outside thereof, a reduction gear module 133 that meshes with the ring gear 131, And a motor 135 for rotating the motor. The reduction gear module 133 and the ring gear 131 are engaged and rotated as the motor unit 135 is rotated and the rotation unit 120 is rotated as the ring gear 131 is rotated.

The driving unit 130 further includes an angle measurement sensor 137 for measuring the rotation angle of the outer shaft 125. [ Since the angle measuring sensor 137 measures the rotation angle of the outer shaft 125, the driving unit 130 can rotate the table 140 and the pallet at an accurate index angle.

The table 140 is installed to be rotatable by the rotation unit 120 on the upper side of the rotation unit 120. An inclined portion 141 is formed on the upper side of the table 140 so as to discharge the chip downward. On the upper side of the table 140, the pallet 160 is fixed. Between the table 140 and the pallet 160, spacers 143 are installed so that the pallet 160 is installed in parallel.

The lower index gear portion 150a is formed in the housing 110. When the table 140 is lowered below the table 140, the upper index gear portion 140a is engaged with the lower index gear portion 150a .

When the table 140 is lifted by the cylinder part 150, the upper index gear part 140a is separated from the lower index gear part 150a. Accordingly, the table 140 can be rotated together with the cylinder portion 150 and the outer shaft 125. [ When the table 140 is lowered by the cylinder part 150, the upper index gear part 140a is engaged with the lower index gear part 150a. Thus, the table 140 is constrained not to rotate.

The cylinder part 150 is disposed between the housing 110 and the rotation part 120 and lifts the rotation part 120 and the table 140 by the fluid.

The cylinder part 150 includes a first cylinder 151 and a second cylinder 155.

The first cylinder 151 is installed so as to surround the rotation part 120. A flange portion 152 is formed on the outer surface of the first cylinder 151 so as to protrude outward. The flange portion 152 may be formed in the shape of a ring along the circumference of the first cylinder 151.

The second cylinder 155 is installed so as to surround the first cylinder 151. The second cylinder 155 houses the flange 152 and has a first hydraulic chamber 157 formed on the upper side of the flange 152 and a second hydraulic chamber 158 on the lower side of the flange 152. [ And a hydraulic chamber 156 in which the hydraulic chamber 156 is formed. The hydraulic chamber 156 may be formed in a ring shape along the circumference of the first cylinder 151. The first cylinder 151 and the second cylinder 155 are rotated together by the driving unit 130. When the fluid is supplied to the first hydraulic chamber 157, the table 140 and the pallet 160 are raised as the second cylinder 155 is lifted.

The table 140 and the housing 110 are coupled by a concave-convex structure to prevent foreign matter from penetrating the chip or cutting oil.

The pallet portion 160 is mounted on the upper side of the table 140, and a fixture portion (not shown) is provided to fix the workpiece. The fixture is fixed so that the workpiece does not move as the fluid is supplied.

The fluid supply line 170 is connected to the rotary part 120, the table 140, the pallet part 160 and the fixture part, and the fixture part supplies fluid to the fixture part so as to fix the workpiece. Since the fluid supply line 170 is formed in the internal structure of the pallet table apparatus, it is not necessary to separately provide a fluid supply device on the upper side of the pallet section 160. Therefore, the structure of the rotating disk 10 is simplified, and the volume of the rotating disk 10 is reduced. Further, since the rotation locus of the rotary disk 10 is reduced, the layout of the machining center can be reduced.

The fluid supply line 170 includes a first supply line 171 formed in the housing 110, a second supply line 172 formed in the rotation unit 120 to be connected to the flow groove 126, A fourth supply line 174 formed in the table 140 to be connected to the third supply line 173 and a third supply line 174 formed in the cylinder part 150 to be connected to the third supply line 173, And a fifth supply line 175 formed in the pallet portion 160 to be connected to the supply line 174 and the fixture portion. Since the fluid supply line 170 is formed in the housing 110, the rotation unit 120, the cylinder unit 150, the table 140 and the pallet unit 160, the volume of the pallet table apparatus 100 can be reduced . Therefore, it is possible to reduce the rotation locus of the rotary disk 10 and reduce the layout of the machining center.

Operation of the pallet table apparatus according to an embodiment of the present invention will be described.

FIG. 7 is a cross-sectional view illustrating a state in which a table and a pallet portion are lifted in a pallet table apparatus according to an embodiment of the present invention, FIG. 8 is a view illustrating a state in which a table and a pallet portion are lowered in a pallet table apparatus according to an embodiment of the present invention Fig.

Referring to FIGS. 7 and 8, a pallet part 160 is loaded with a workpiece, and fluid is supplied to the fluid supply line 170. The fluid supplied to the first supply line 171 is supplied to the second supply line 172. The fluid in the second supply line 172 is supplied to the third supply line 173 of the cylinder portion 150 through the flow groove portion 126 between the inner shaft 121 and the outer shaft 125. The fluid in the third supply line 173 is supplied to the jig via the fourth supply line 174 and the fifth supply line 175. As the fluid is supplied to the jig portion, the work material is fixed to the pallet portion 160 so as not to move.

Further, the fluid is supplied to the second hydraulic chamber 158 of the cylinder portion 150. [ When the fluid is supplied to the second hydraulic chamber 158, the flange portion 152 is pressed upward by the hydraulic pressure of the second hydraulic chamber 158. As the flange portion 152 is raised, the first cylinder 151 slightly rises. The table 140 and the pallet 160 are raised as the first cylinder 151 is raised. The upper index gear portion 140a of the table 140 is separated from the lower index gear portion 150a of the housing 110 as the table 140 is lifted. As the driving unit 130 is driven, the pallet unit 160 is rotated at a certain angle.

When the pallet portion 160 is rotated at a certain angle, the fluid is discharged from the second hydraulic chamber 158 and the fluid is supplied to the first hydraulic chamber 157. As the hydraulic pressure in the first hydraulic chamber 157 rises, the flange portion 152 is lowered. The upper index gear portion 140a of the table 140 is engaged with the lower index gear portion 150a of the housing 110 as the table 140 is lifted. When the upper index gear portion 140a is engaged with the lower index gear portion 150a of the housing 110, the table 140 is restrained not to rotate.

Since the fluid supply line 170 is connected to the rotary part 120, the table 140, the pallet part 160 and the jig part as described above, it is not necessary to separately provide a fluid supply device on the pallet part 160 . Therefore, the structure of the rotating disk 10 is simplified, and the volume of the rotating disk 10 is reduced. Further, since the rotation locus of the rotary disk 10 is reduced, the layout of the machining center can be reduced.

When the table 140 is lifted by the cylinder part 150, the upper index gear part 140a is separated from the lower index gear part 150a so that the table 140 rotates around the cylinder part 150, (Not shown). Thus, the workpiece can be rotated to the correct machining position.

When the table 140 is lowered by the cylinder portion 150, the upper index gear portion 140a is engaged with the lower index gear portion 150a. Therefore, the table 140 is constrained not to be rotated during processing of the workpiece.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

Accordingly, the true scope of protection of the present invention should be defined by the claims.
