Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a wood boring machine that automatically drills holes at necessary locations in board materials for making building materials, furniture materials, etc.

[Conventional technology]

Conventionally, the apparatus for making holes in a plate material is one in which a drill is moved to a predetermined position on a workpiece plate material using a manual handle or the like, and the drilling operation is performed after the drilling operation is performed.

Therefore, it is time-consuming and does not improve work efficiency. [Object of the Invention] The object of the present 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. The object of the present invention is to obtain a boring machine for woodworking that can be put away in a position where it will not become damaged.

[Structure of the invention]

The present invention consists of a mechanism for fixing a plate to be processed at a predetermined position on the machine body, a group of upward drills provided on the machine body for drilling a required number of holes to a predetermined depth from the bottom of the fixed plate to be machined, and a group of upward drills installed in the machine body. A group of sideways drills that drill holes into the green surface of the workpiece protruding from the mounted fixed body and the movable body facing the fixed body, and a group of horizontal drills with the upper end rotatable above the machine. This woodworking boring machine consists of a pivotally supported U-shaped arm and a plate holding member that moves up and down with a cylinder attached to the lower end of the U-shaped arm.

〔Example〕

In FIG. 1, reference numeral 1 denotes a pair of body frames erected on the left and right sides of a base 2, with a beam 3 extending between the upper ends of both body frames 1,1.

This beam 3 is provided with guide rails 4, 4 and 6, 5 for each pair at the top and bottom along the longitudinal direction (see Fig. 4).
Five supports 7 of a pressing member 6 that presses the plate material B are slidably mounted on the upper guide rails 4, 4, and the supports 7 are slidably mounted.
Through-holes 8 are formed in the horizontal direction at locations, and in the illustrated embodiment, screw punches 9 are passed through five of the locations. As shown in FIGS. 1 and 5, the screw threads 9 arranged in two stages are supported at both ends by bearings 10, 10 fixed to the beam 3, and one end is connected to the rotating shaft 12 via a clutch 11. , the gears 13 attached to the rotating shaft 12 are engaged with each other in each row,

Each thread village 9 is fixedly attached to the through hole 8 of each support 7 and has an internal thread 2.
0, and as the screw punch 9 rotates, each support body 7 is moved left and right along the guide rail 4.

The support body 7 has a bearing 21 on its upper surface and a U-shaped arm 22 (the fourth
) is pivoted and suspended by a shaft 23, a pneumatic cylinder 24 is attached to the lower end of the new curve, and a rod 2 integrated with the piston 25 is attached.
The pressing member 6 is attached to 6 via a pin 27,
A vertical guide punch 28 erected on the pressing member 6 is inserted into a hole 29 in the arm 22, and a plywood 31 supporting another pneumatic cylinder 30 provided above is attached to an underframe 32 integral with the support 7. 33, and the piston punch 34 is supported by a pin 36 on the pin piece 35 at the upper end of the arm 22. Due to the movement of the piston punch 34, the arm 22 is raised together with the pressing member 6 as shown by the chain line in FIG. It will be done.

In other words, if the dimensions of the plate material are short or otherwise unnecessary, press the pressing part 6,
It 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 attached to the lower part of the arm 22 with a pin 39 via a mounting piece 38, and a hook-shaped metal fitting 4 that locks the piston village 401 to the guide rail 5.
1 is connected by a pin 42, and the bent portion of the hook-shaped metal fitting 41 is supported by a pin 43 on a supporting member 44 that is integrated with the arm 22. By the action of the pneumatic cylinder 37, the hook-shaped metal fitting 41 is connected to the beam 3.
It bites into the guide rail 5 and fixes it. Reference numeral 45 in FIG. 4 denotes a cushion of the arm 22, which is inserted into the guide tube 46 provided on the support body 7 and acts upwardly with a 'mimetic' 47, so that the tip of the cushion 45 comes into contact with the contact portion 48 of the arm 22. So,
The spring 47 provides a cushioning effect when the arm 22 is lowered. In FIG. 4, numerals 49 and 50 are compressed air delivery pipes into the pneumatic cylinder 24. Furthermore, as shown in FIGS.
301 upward-facing drills 51 are supported in one row with 21 pieces.

All five rows of drills 51 are moved up and down by the pneumatic cylinder 68, and the cylinder 64
In some cases, each column moves up and down independently. That is, during drilling work, the gearbox 62 is raised in advance using the cylinder 64, and then the pneumatic cylinder 68 is activated, and the drilling work is performed by the raising of the gearbox 62, which is not used because the plate material is narrow. If there is a drill row, by lowering the cylinder 64 only in that row, all 5
Even when a row is raised by the pneumatic cylinder 68, drilling is not performed only in that row, and as the pressing member 6 disposed on the arm 22 is raised, an escape action is performed. 65 in Figure 3 is
Five rows of lower surface support rails are provided for the plate material B which is pressed by the pressing member 6 (FIG. 1). can be attached to both ends and fixed with set screws 66b.

Reference numeral 67 indicates a moving surface of the support beam 56, which projects inside the fuselage frame 1.

For this vertical sliding action, there are pneumatic cylinders 68 provided at both ends of the support beam 56, a pinion 69 (Fig. 2), and a fuselage frame 1.
This is done using a rack 70 fixed to. That is, the piston 68' of the pneumatic cylinder 68 is fixed to the fuselage frame, and the pinion 69 meshes with the rack 70 and is moved up and down by the pneumatic cylinder 68. At this time, the pinion 69 is connected to the support beam 56.
It is attached to move the left and right ends of the machine up and down in parallel. Reference numeral 71 in FIG. 1 indicates left and right horizontal drills, which protrude 21 times opposite the movable body 72 hanging down from the guide rail 5 and the fixed body 73 on the opposite side.

The rotation mechanism is a shaft 75 of a motor 74 as shown in FIG.
This is done by connecting the gear 76 fixed to the drill support shaft 77 with the gear 78 of the drill support shaft 77 through the gear 79 of the intermediate shaft 80. Furthermore, at the end of the shaft tube 81 through which the motor shaft 75 is inserted, there is a gear support portion. The motor 74 is fixed at the base, and the piston 83 is fixed to the piston 81 to form the cylinder 84.
