Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wood boring machine that automatically drills holes at necessary locations in board materials used to make building materials, furniture materials, etc.

[Conventional technology]

Conventionally, the apparatus for drilling a hole in a plate material uses a manual handle or the like to move a drill to a predetermined position on the plate material to be processed, and then performs the drilling operation.

Therefore, it is time-consuming and does not improve work efficiency.

[Purpose of invention]

The purpose of this invention is to improve work efficiency by automatically controlling not only the movement of the drill, but also its selection, rotation, plate pressing support mechanism, etc., and it is also possible to select and use only unnecessary drill groups. The objective is to obtain a boring machine for woodworking.

Due to this movement, the arm 22 is lifted together with the pressing member 6 as shown by the chain line in FIG. That is, if the pressing member 6 is unnecessary, such as because the size of the plate is short, the pressing member 6 is raised to a position where it does not interfere with the movement of a moving body 72 (FIG. 1), which will be described later. Furthermore, a pneumatic cylinder 37 is pivotally mounted below the arm 22 via a mounting piece 38 with a pin 39.
A hook-shaped metal fitting 41 that locks on the guide rail 5 is connected to the piston rod 40 by a pin 42.

[Operation of the idea]

Depending on the desired size of the plate material B and the drilling position, the cylinder 64 is used to raise the upward drill 51 by a desired number of rows, and then the pneumatic cylinder 68 is used to make holes, and the drills in the rows that are not raised by the cylinder 64 are drilled. No work will be done. Before drilling, the pressing member 6 is moved almost directly above each row of drills using the screw rod 9 to set the drilling position, and the movable body 72 is further moved to the left in FIG. 1 depending on the width of the plate material B. Then, the workpiece B is placed in a position close to the edge of the workpiece, and then the workpiece conveyor belt 108 transfers the workpiece B to the limit switch LS.
1 and after the material feeding has stopped, push the piece 101
The plate B is brought into contact with the stopper 100 by the movable ruler 93, and the fixed ruler 94 is pressed by the movable ruler 93, and the upper surface of the plate material is pressed by the pressing member 6, and the clamping of the plate material B is completed.Then, the drilling operation is performed at the desired position. After finishing, the stopper 100 rises to release the clamps of all the workpieces, including the retraction of the pusher piece 101, and with this release command, the conveyor belt 108 is operated and the plate material B hits the limit switch LS2 and then moves to the opposite side. . The stopper 100 is lowered again by contact with the limit switch LS2. Further, the pneumatic cylinder 30 is operated to raise the U-shaped arm around the fulcrum of the shaft 23 to the position indicated by the chain line in FIG. 2 so that it does not interfere with the movement of the movable body 72.

[Effect of idea]
