An example of the shape of the joint constituting the joint is shown in Figure 5 (A>
, (B), and the hanging tenon with a large insert shown in Figure 6 (A>, (B)) are known, and these can be used as bases, daihiki, or to join the body sash and joists, depending on the purpose. It is used as appropriate.

As a process (2) for performing the above-mentioned mortise process, the process proposed in Japanese Utility Model Publication No. 58-20323 is well known.

According to this processing machine, each of the above-mentioned grooves can be formed by the vertical movement of the cutter, or by a combination of vertical movement and circular arc movement, and it is easy to operate and has a unique mortise and tenon accuracy. It is widely used in this industry because of its strength of 1q.

By the way, when specifically performing tenon processing with this processing machine, for example, when performing a mortise on the longitudinal side surface of the workpiece W, as in the female groove processing shown in FIG. 6(B), the tenon As shown in the figure, the workpiece ~■ is placed horizontally on a table and fixed between two horizontal vises 40a and 40b. A),
When performing tenon processing on the wood end as shown in (B), the workpiece W is placed on a table in the front-rear direction as shown in the figure, and this is fixed in a vertical vise 40c. However, it was necessary to adjust the cutting position of the cutter based on the marked line marked on the upper surface of the workpiece.

(Problem to be Solved by the Invention) The above adjustment work was performed by visually observing an indicator (not shown) on the cutter side corresponding to the marked line and matching the two. The vise means is equipped with a movement adjustment mechanism, and the above setting can be performed by moving the material in the desired direction while clamping it.
In addition, the workpiece was finely adjusted and set by hand feeding. Therefore, in either case, the adjustment is performed on the long and heavy material, which places a heavy burden on the operator and makes it difficult to carry out the work quickly. It also had the disadvantages of having separate grooves in the vise, a complicated table mechanism, and an increase in size.

The purpose of this invention is to solve the above-mentioned problems of the prior art.The present invention is aimed at solving the above-mentioned problems of the conventional technology. The purpose is to provide a configuration device.

Further, the processing cutter side is provided with position indicating means for indicating the position of the processing cutter in the left and right direction.

(Function) After the workpiece is clamped and fixed by the clamp means, the operation switch is used to adjust the movement of the processing cutter in the left-right direction. Then, the positional relationship between the two is visually observed using an indicating means on the cutter side that corresponds to the marked line on the workpiece, and thereby the position of the processing cutter with respect to the workpiece is set. This is then used as a cutting reference position in preparation for the next cutting process, and the adjustment work is performed by motor drive to speed up and simplify the work.

Since the cutter has been adjusted, the initial setting of the cutter based on the marked line can be quickly and easily performed with a simple switch operation. In addition, since there is no adjustment means on the workpiece side, the structure can be reduced to a small size 1~, which is an advantage.
