It is possible to process L-shaped materials, etc., and it is also very easy to replace saws, cutters, etc. with respect to the rotating shaft.Furthermore, the material feeding table 1 is made of a fan-shaped plate having a center vertically on its upper surface. 21. Since it is attached to the machine base 20 by 21, even if the material feeding table 1 is tilted to the left or right, the center will not shift. Therefore, the material deviation when the material feeding table is tilted is minimized, and the cutter is positioned. There is no need to change
All kinds of processing can be conveniently performed as is.

As described above, in the universal woodworking machine according to the present invention, the material feeding table is mounted on the machine base using a fan-shaped plate whose center is aligned with the longitudinal center line of the upper surface of the material feeding table, and the material feeding table is rotated in the width direction. A pair of columns are erected above the material feeding table on one side with respect to the longitudinal center line of the material feeding table, and a holder corresponding to the material feeding table is supported by the second column, This holding body can be adjusted up and down by an adjusting means, and the holding body supports two sets of front and rear feeding members that are cantilevered on the column side. A corresponding frame is erected on the machine stand between the columns, a vertical guide is provided on the frame, and this guide supports an elevating plate which is raised and lowered by an adjusting means, and the elevating plate is provided with a vertical guide. A rotary shaft protruding between the two sets of feeding members is provided so as to be cantilevered on the guide side, and a rotary cutter is attached to the rotary shaft in alignment with the longitudinal center line of the material feeding table. Therefore, when the angle adjustment mechanism is operated, the angles of the material feeding table and the feeding member are adjusted at the same time without changing the relative relationship, and the relative relationship between the material to be transferred and the rotary cutter fixed to the rotating shaft is adjusted. The angle can be changed freely, and the feeding member moves up and down the column to change the distance from the material feeding table, and regardless of the thickness of the material, it can be sandwiched between it and the material feeding table. This function reliably performs the function of attaching and transporting.

In particular, the rotating shaft located above the material feeding table moves up and down along the column, and the distance between it and the material feeding table can be arbitrarily changed to freely change the depth of cut into the material, so it is necessary to increase the number of rotating shafts. Depending on the processing conditions, the rotary blade can be used as a circular saw, straight blade cutter, or
If you convert it into a curved blade cutter, groove cutter, etc., adjust the angle appropriately, feed the material between the material feeding table and the feeding member, and transfer it, you can cut and cut various materials with a circular saw. It is possible to perform versatile and accurate cutting of materials with a straight blade cutter, round chamfering of materials with a flat or curved blade cutter, and grooving of materials with a grooving cutter. It is something.

In addition, this all-purpose woodworking machine automatically feeds the material using the feeding member, so there is no need for manpower and there is no danger in the processing work, and the feeding of the material is stable and continuous due to the lower surface support of the material feeding table. This method is highly effective in improving machining accuracy and work efficiency.

Furthermore, this woodworking machine has a rotary blade placed above the material feeding table, which processes the upper surface of the material, so it is possible to perform sawing, cutting, etc. of the material while maintaining the processing state, making it possible to control the processing. This is extremely convenient, and when processing conditions are poor, it can be immediately changed to eliminate the occurrence of defective products.

In addition, in this versatile woodworking machine, the material feeding table is attached to the machine body using a fan-shaped plate whose center is aligned with the longitudinal center line of the top surface, and even if the material feeding table is tilted in the width direction, its center will not shift. Therefore, there is extremely little deviation of the material relative to the cutter when the material feeding table is tilted, and therefore, there is no need to change the position of the cutter, and all kinds of processing can be conveniently performed without changing the position of the cutter. Since the workpiece and the rotating shaft are cantilevered and the machining gap is opened on one side, if this open part is used as the front of the work, one person can supply and take out the material in the case of short materials, and the material can be placed in the open part. If you look at a part of the machine, you can process half-faces of wide materials, process deformed materials such as L-shaped materials, and have the convenience of being able to attach and replace various cutters on the horizontal spindle very easily. It is.
