That is, the fixing table is vertically moved up and down vertically by a vertically moving cylinder, and a plurality of protruding grooves are formed, and each of the plurality of protruding grooves has a pressing protrusion inserted therein. The pressing protrusion is coupled to the fixing table, .

A spring (44) is mounted between the lower surface of the fixing table and the end of the pressing projection.

Accordingly, when the lid of the oil port that is seated on the seat is pressed and fixed while being moved in the downward direction, the pressing protrusion of the pressing portion comes into contact with the upper surface of the lid of the oil port and moves upward.

At this time, the spring mounted between the end of the pressing projection and the lower surface of the fixing table is compressed, and the lid of the filling port seated on the mounting table is further firmly fixed at the upper portion.

In addition, the fixing table is coupled to the revolving shaft 45 and rotated in the same direction as the mounting table while fixing the lid of the filling port seated on the mounting table.

That is, the fixing base is a pressing protrusion coupled to a fixing base and presses and fixes a lid of a filling port seated on the mounting base, wherein the fixing base presses the lid of the filling port seated on the mounting base and is rotated in the same direction by rotation of the mounting base .

The burr formed at the edge of the filler port lid is processed by a cutting jig.

Further, when the cutting jig is used to finish burr forming on the edge of the lid of the oil port, the pressing portion is moved upward.

At this time, the fixing base of the pressing portion is moved upward, and the pressing projection mounted on the fixing base, which is in contact with the upper surface of the filling port cover, is moved in the downward direction by the restoring force.

Meanwhile, the cutting jig for removing the burr formed on the filler port cover includes a bite that contacts the edge of the filler port lid fixed to the upper surface of the mount table, a body that fixes the bite, and a horizontally moving cylinder that presses the body in the mount base direction Wherein the body and the horizontal movement cylinder are coupled to the support frame.

A rail is formed on an upper surface of the support frame, and the rail is engaged with a rail groove formed on a lower surface of the body.

In this case, the lid of the oil port that is seated on the seat is rotated in the horizontal direction by the rotary motor, and the burr formed on the edge of the lid of the main lug is cut by the bite coupled to the cutting jig.

At this time, the bite is coupled to the body and moved in the direction of the seat by the pressure of the horizontal movement cylinder.

Further, the tube is coupled to the upper surface of the support frame, and the rod is coupled to the body.

When the external force applied to the rod of the horizontally moving cylinder is higher than the pressure inside the tube, the rod moves to the inside of the tube. Explaining the reason why the rod is moved to the inside of the tube by external force, Because.

And the external force applied to the rod is generated while coming into contact with the edge of the lid of the oil port which is seated on the seat and rotates.

On the contrary, when the pneumatic pressure supplied to the vertical movement cylinder exceeds 6 Mpa, the force to press the lid of the oil port that is seated on the seat is strong, so that the defective product with deformed shape of the lid of the oil port can be produced.

Also, when the pneumatic pressure supplied to the horizontally moving cylinder is less than 0.5 MPa, the force for pushing the bite in the direction of the seat cushion is insufficient, so that the burr formed on the lid can not be removed.

That is, since the rotational force of the oil port lid which is seated on the seat belt and is rotating is stronger than the force pushing the seat belt in the seat belt direction, the bite is pushed back without cutting process.

In contrast, when the pneumatic pressure supplied to the horizontally moving cylinder exceeds 2Mpa, a force pushing the bite in the direction of the seat back is seated on the seat so as to be stronger than the rotating oil lid rotating force, .

Accordingly, the pneumatic distributor plays an important role in distributing the air pressure to the horizontally moving cylinder and the vertically moving cylinder accurately, thereby preventing defective products from being generated when the lid is removed from the lid.

In addition, on the upper surface of the workbench, a burr discharge port 13 is formed in a downward direction so that burrs generated during work can be primarily stored.

That is, on the upper surface of the workbench, a burr outlet is formed at a position where the cutting jig and the seat are opposed to each other, and the burr formed in the lid of the filler port is cut by the cutting tool jig.

Accordingly, the burr can be put into the burr outlet formed on the upper surface of the workbench and can be arranged in a primary order.

After the work is finished, you can use the second gun to clean up the remaining burrs.

In addition, a moving wheel 14 is installed at a lower portion of the workbench so that the workbench can be easily moved and the worker can work at a convenient position.
