Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wood processing machine that processes large inserts, large dovetails, dovetail grooves, etc. in order to join pieces of wood together.

Conventionally, the above-mentioned large inserts, large dovetail hooks, etc. have been processed using only a hand saw or hand, or with a router bit, but manual processing is time consuming and inefficient. In addition, machining with a router requires hand-held work, which not only makes it impossible to obtain high-precision cutting, but is also dangerous, and the bits must be replaced each time depending on the type of machining, which is troublesome.

Therefore, as a result of studies in view of the above-mentioned conventional circumstances, the present invention has been developed so that it can be attached to a workpiece using a vise mechanism.
The main body of the processing machine is movably and rotatably supported by the vice mechanism mentioned above, and depending on the type of cutting process, the main body of the processing machine can be rotated 180 degrees to use the flat bits and dovetail bits attached to both ends of the blade arbor as appropriate. This is a wood processing machine that saves you the trouble of replacing bits.The rotation direction of each bit can be maintained constant even when the processing machine body rotates, and the motor cooling air is discharged to the side of the bit in use. By doing so, a wood processing machine which can eliminate cutting waste and is extremely convenient to use has been obtained.

are provided with scale plates 51 and 52 with movement distances marked thereon, and scale indicating hands are provided on the left and right sliding bases 21 and the front and rear sliding bases 36 opposite to these scale plates 51 and 52, and A center indicator needle 63 is provided at the center of the base 36 to face the bit center of the main body A of the processing machine.

As shown in FIGS. 4 to 6, the clamp mechanism 50 includes a supporter 34 and a front and rear guide bar 35.
A hole is provided parallel to the outer vice guide bars 54, 54 which are slidable in the hole and are connected and fixed at both ends by holders 53, 53, respectively. Inner vise guide bars 56, 56 for sliding the vise holder 55 are fixedly installed in the center of the holders 53, 53, and sliding and fixing of the outer vise guide bars 54, 54 to the supporter 34 is achieved by tightening and tightening screw bolts 57. People are starting to do it more slowly. Also, the sliding of the vise holder 55 is prevented by the vise holder 55.
The holder 53 is tightened with either one of the holders 53 by tightening a threaded bolt 58.

The vise holder 55 has a chuck holder 59, and the chuck holder 59 can be slid in a direction orthogonal to the workpiece 32 by rotating the vise handle 60.
At 9, the workpiece 32 is inserted by rotating the screw-in knob.
It has a clamp plate 62 for crimping.

Then, the side plates 37 and 37' are applied to the upper surface of the workpiece 32, and the workpiece 32 is clamped between the vise 33 and the clamp plate 62 by operating the vice handle 60, and the upper surface of the workpiece 32 is clamped to a predetermined position. Fix the processing machine main body A in position.

Next, move the processing machine main body A using the forward and backward feed handle 39.
Move it toward you (downward in Figure 4),
Loosen the lever handle 25 and move the vertical feed handle 4
5, the processing machine main body A is lowered together with the slide plate 19 relative to the left and right sliding base 21, thereby feeding the bit 14 or 15 to the depth of cut,
Thereafter, the lever handle 25 is tightened to fix the processing machine main body A to the left and right sliding base 21.
If the operation switch SW ₁ is turned ON in this state, the motor M rotates and the bits 14 and 15 are driven and rotated, so the necessary cutting depth and cutting depth can be achieved by feeding the front and rear feed handles 34 and the left and right feed handles 42. Once the width is obtained, cut to the desired depth and width.

By the way, the router bits 14 and 15 are changed depending on the type of cutting, such as large cutting or large dovetailing, but in this case, loosen the lever handle 25,
Furthermore, loosen the center bolt 20 using the knob 23 and the tightening screw 22, and then move the processing machine main body A at 180 degrees with respect to the slide plate 19, that is, the left and right sliding base 21.
After rotating the blade cover 27, tighten it with the tightening screw 22 and lever handle 25.
The bits that were previously used are stored inside the blade cover 27, while the bits that were previously stored inside the blade cover 27 are exposed and can be used.

When switching bits like this, one of the limit switches SW ₂ , SW ₃ comes into contact with the limit lever 30, and the limit switches SW ₂ , SW ₃
performs a switching operation and reverses the direction of rotation of the motor M.

To explain this, while the processing machine main body A is rotating, both limit switches SW ₂ and SW ₃ are in the connected state shown in FIG. 9, and the motor M is not energized and is stopped. From this state, remove the processing machine body A.
When rotated 180 degrees, SW ₂ switches when it comes into contact with the limit lever 30, and power is applied from the power plug P to the armature 8 via the operation switch SW ₁ and limit switch SW ₃ , and from the armature 8 to the limit switch SW ₂ and the field. A circuit is formed so as to extend through the coil 10 and further through the operation switch _SW1 to the power plug P.

When the processing machine main body A is further rotated 180 degrees, the limit switch SW ₂ returns to the connected state shown in FIG. 9, and at the same time, the limit switch SW ₃ switches to the other contact. For this reason, the power plug P
Power is supplied to the amateur ₈ from the amateur 8 through the operation switch SW 1 and the limit switch SW ₂ , and then from the amateur 8 to the limit switch SW ₃ , the field coil 10, the operation switch SW ₁ , and the power plug P.
Therefore, each time the processing machine main body A, that is, the motor case 1 is rotated, the connection state of the armature 8 to the field coil 10 is reversed, and the direction of rotation is also reversed accordingly. .

In this case, the motor case 1, that is, the blade arbor 9, is reversed 180 degrees to selectively use both bits 14 and 15, so which bit is used depending on whether the rotation direction of the motor M is forward or reverse. is also the same forward rotation. However, since the rotation direction of the fan 8a attached to the rotating shaft 8b of the armature 8 is also rotated in the direction corresponding to the rotation direction of both bits, the motor cooling air is directed to the bit being used through the air hole of the motor cover 2 or belt cover 3. 2a or 3a
Since the cutting waste of the workpiece 32 caused by the used bit is discharged through the hole, the cutting waste of the workpiece 32 caused by the used bit is removed.

As explained above, according to the wood processing machine according to the present invention, the processing machine main body A is movably and rotatably supported by the vise mechanism B so as to be freely attached to the workpiece 32, and This is a wood processing machine in which bits 14 and 15 attached to both ends of a blade arbor 9 that is driven and rotated are used appropriately by rotating the processing machine main body A by 180 degrees depending on the type of cutting process, A switch mechanism is provided so that the direction of rotation of the motor M is reversed between forward and reverse by the rotation of A, and a motor cooling fan 8a is attached to the armature 8, and the motor cooling air from the fan is distributed to the motor cover 2 and the belt cover. Air holes 2 provided on the end faces of 3
Since the structure is such that the bits are discharged through a and 3a to the used bit side, the processing machine body A can be rotated 180 degrees depending on the type of cutting process to use the bits as appropriate, thereby saving the trouble of replacing bits. Of course, by rotating the processing machine body A to use each bit properly, the direction of rotation of each bit can be maintained in the forward direction without any switching operation, and the motor cooling air can be maintained. It is possible to reliably discharge only to the used bit side,
The wind can remove cutting debris, etc.
Moreover, since the motor cooling air is discharged from the air holes 2a and 3a provided on the end faces of the motor cover 2 and the belt cover 3 toward the cutting part by the bit used, it is possible to ensure the removal of cutting waste.
The black lines are always clear and easy to cut, and the machining accuracy can be improved, making them very convenient to use.
