Description

  The present invention relates to a 5-axis machining apparatus in which a cover connected with an elbow duct is mounted around a tool of a swing head, and machining is performed while sucking wood chips accumulated in the cover.

  Conventionally, as this type of 5-axis machining apparatus, as shown in FIGS. 8 to 10, two rails 2 are mounted on a base 1, and a bearing 3 that engages with the rails 2 is a lower part of a table 4. The table 4 is configured to have a large number of micro holes on the upper surface to adsorb the workpiece, or to fix the workpiece by other means, and is fixed to the base 1. The first servo motor 5 is moved back and forth to be positioned at a desired position.

  A rail 6 is mounted on the front surface of the support member 1a mounted on the base 1 so as to straddle the table 4, and a bearing 7 engaged with the rail 6 is fixed to the lateral movement member 8, and the support member 1a. The lateral movement member 8 is configured to move on the front surface of the support member 1 a by the second servo motor 9 mounted on the upper surface 10, and the upper head 10 is mounted on the lateral movement member 8 on the front surface of the lateral movement member 8. The third servo motor 11 is moved up and down to be positioned at a desired position.

  Further, a fourth servo motor 12 is mounted on the upper head 10, and the lower head 13 rotatably mounted on the lower portion of the upper head 10 transmits the rotation of the fourth servo motor 12 to the bevel gear. As shown in FIGS. 8 and 9, the lower head 13 is composed of bifurcated portions 13a and 13b, and a fifth servomotor 14 is built in the bifurcated portion 13a. The swing head 15 is configured to be rotated from the horizontal direction to the vertical direction between the bifurcated portions 13a and 13b, and is mounted on the end of the swing head 15 by a motor mounted on the swing head 15. A configured tool (not shown) is configured to be rotated.

However, in the conventional 5-axis machining apparatus configured as described above, when machining wood is machined with a tool attached to the head, wood chips are scattered, and the machined parts on the machined wood are shifted by the wood chips, so that the machined parts are processed. There was a problem that was not processed accurately.

    The problem to be solved is that when the machined wood is machined with a tool attached to the head, the wood chips are scattered, and the machined parts on the machined wood are shifted due to the wood chips and the machined parts are not processed accurately. is there.

  According to the present invention, a table for mounting a workpiece is mounted on a base so as to be movable back and forth by a first servo motor, and a lateral movement member is mounted on the support member mounted on the base by a second servo motor. Mounted movably in a direction orthogonal to the moving direction, mounted with a third servo motor mounted on the laterally movable member so that the vertically movable member can be moved up and down, and mounted an upper head on the vertically movable member, A lower head rotated by a fourth servo motor is mounted under the upper head, a swing head is rotated by a fifth servo motor mounted on the lower head, and a motor is mounted on the swing head. In the 5-axis machining apparatus, a cover that covers the periphery of the tool of the swing head is mounted, a brush is mounted around the lower end of the cover, and a cylinder that moves the cover up and down is mounted on the swing head. Attach an elbow duct to the side of the cover, connect a bendable elastic duct to the end of the elbow duct, and attach a disc-shaped duct that rotates with the lower head to the top of the lower head, A suction duct is mounted on the upper surface of the disk-shaped duct, and a connection duct connected to the elastic duct is mounted on the lower surface of the disk-shaped duct, and the cylinder is used when changing the tool of the swing head. In the above, the bar is raised and the cover is lowered with the cylinder when processing the processed wood, and the wood chips collected during processing inside the brush at the lower end of the cover are elbow-type duct, elastic duct, connection duct and disc shape It is processed while always sucking through the duct.

  The present invention attaches a cover that is moved up and down by a cylinder around the tool at the lower end of the swing head, attaches a brush around the lower end of the cover, and lowers the brush during processing to scatter the tool. Since the wood chips are separated from the surroundings, the wood chips are processed while being always sucked through the elbow ducts, the elastic ducts, the connection ducts and the disc-shaped ducts. When the tool is changed, there is an advantage that interference with the changing device can be prevented by raising the cover by the cylinder.

  In the present invention, a cover on which a brush for dust collection of dust is attached is mounted around the tool of the swing head, an elbow duct is provided on the cover, and a connection duct is connected to the elbow duct via an elastic duct. As a result, even if the swinging head is bent, it is configured to follow the bending, and wood chips generated when processed with a tool can be reliably sucked.

    1 is a partially sectional front view of the lower head of the 5-axis machining apparatus of the present invention, FIG. 2 is a right side view of the lower head of FIG. 1, and FIG. 3 is a partially sectional side view of the lower head of FIG. Is a lower head, 13a and 13b are bifurcated portions, 14 is a fifth servo motor, 15 is a head swing, and a motor for rotating the tool is mounted, and these configurations are the same as the conventional example, Although not described, in this embodiment, a suction part 17 is attached to the upper part of the lower head 13, and a suction duct 18 connected to a suction device (not shown) is attached to the upper part of the suction part 17. The connection duct 19 is attached to the lower part of the suction part 17, the cover 20 is attached to the lower end of the swing head 15, the brush 21 is fixed to the lower end of the cover 20, and the interior of the cover 20 is attached to the side surface of the cover 20. Elbow type duct 22 communicating with the The elastic duct 23 is connected to the end of the elbow duct 22 and the outside of the connection duct 19, and a cylinder 24 is attached to the side of the swing head 15. 24 a is connected to the upper part of the cover 20, and the guide 25 is supported by the support member 26. By driving the cylinder 24, the cover 20 moves downward along the swing head 15 as shown in FIG. 4. Is configured to do.

  In the 5-axis machining apparatus of the present embodiment configured as described above, the vacuum device is driven during machining, and the air in the cover 20 is passed through the suction portion 17, the connection duct 18, the elastic duct 23, and the elbow-type duct 22. Next, when the cylinder 24 mounted on the swing head 15 is driven to move the cover downward and the tool is rotated by a motor mounted on the swing head 15, the wood chips generated by the processing are removed. Therefore, the dust is scattered in the cover 20 and is sent from the cover 20 to the suction part 17 through the elbow-type duct 22, the elastic cover 23 and the connection duct 18, and is collected from the suction part 17 through the suction duct 18 by the suction device. Even if the swing head 15 is swung left and right as shown in FIGS. 6 and 7, the connection duct 19 and the elbow-type duct 22 are not detached by the elastic duct 23. It is possible to continue the suction of wood chips in.

  In the above description, the connecting duct 19 and the elbow-type duct 22 are connected by the elastic duct 23. However, a synthetic resin can be used as this member, and instead of this elastic duct, A bellows-like duct can be used.
