2. Description of the Related Art For example, when woods are combined and joined together, one wood is formed with a joint projection (mortise) and the other wood is formed with a joint recess (mortise). There is a method of fitting a tenon. 11A and 11B show a tenon-shaped tenon and a tenon, in which a tenon 55 (FIG. 11A) formed on one piece of wood W1 is fitted into a tenon 56 (FIG. 11B) formed on the other piece of wood W1.

FIGS. 11C and 11D show dovetail mortises and mortises, and a tenon 55 (FIG. 11C) formed on one piece of wood W1 and a tenon 56 (FIG. 11D) formed on the other piece of wood W2. To fit. FIGS. 11A, 11B, and 11C show a mortise for forming a tenon and a tenon at the tip of the wood W1.
FIG. 11D shows a joint processing for forming a tenon on the side surface of the wood W2.

[0004] As a conventional processing machine for cutting such a tenon and a tenon, there is a joint processing machine described in Japanese Patent Application Laid-Open No. 1-275003. This connection processing machine is shown in FIG.
As shown in FIG. FIG. 12 is a partial cross-sectional side view, and FIG.
3A is a cross-sectional plan view, and FIG. 13B is a perspective view showing details in the vicinity of the contact piece 301.

[0005] In the case of performing a woodcut processing for processing the tip end surface of the wood W1, the wood W1 to be processed is placed on the table 80 in the vertical direction (the directions of arrows 94 and 95), and the vertical vise piece 3 is set.
Fix using 04. The vertical vise piece 304 is centrifugally closed by rotating the operation handle 306, and fixes the wood W1 in between. In the case of performing a joining process for processing the side surface of the wood W2, the wood W2 is placed on the table 80 in the horizontal direction (the directions of arrows 92 and 93) and fixed using a horizontal vise piece (see FIG. 13A). ). The horizontal vice piece is centripetally closed by rotating the operation handle 307 to fix the wood W2.

After fixing the wood W1 or the wood W2, cutting is performed by the cutter 83. This cutter 83
Is rotated by a cutter motor 84. The cutter 83 and the cutter motor 84 are mounted on a mounting base 72 as shown in FIG. 12, and the mounting base 72 is further held by an elevating body 87.

The elevating body 87 is attached to the vertical guide rail 86 by an arrow 9
It is attached to be able to move up and down in directions 0 and 91. The drive of the vertical movement motor 81 is transmitted to the lifting / lowering body 87 via the feed screw shaft 85, and the lifting / lowering body 87 is pointed by arrows 90 and 91.
Control the elevation in the direction. The elevating body 87 is provided with a lateral guide rail 88, and the mounting base 72 holding the cutter 83 and the cutter motor 84 moves in the lateral direction along the lateral guide rail 88. The lateral movement is performed by a lateral movement motor 82 provided on the elevating body 87.
Is controlled by

The mortise (FIG. 11B, D) is cut by moving the cutter 83 in the direction of the arrow 90 by driving the motor 81 for vertical movement. The tenon (Fig. 11)
A and C) show a vertical movement motor 81 and a horizontal movement motor 82.
The cutting is performed by moving the cutter 83 in accordance with the combination in the vertical and horizontal directions by the driving of. By replacement, a mortise and a cutter 83 having a shape corresponding to the mortise are used.

By the way, in order to cut an appropriate tenon and tenon, it is necessary to accurately align and fix the woods W1 and W2 with respect to the cutter 83. For this reason, this conventional joining machine has a positioning contact piece 301 provided below the mounting base 72 as shown in FIG.
FIG. 13B shows the details of the positioning contact piece 301.

[0010] In the case of performing the opening process, the tip end surface of the wood W1 is brought into contact with the positioning abutment piece 301 so as to be vertically aligned (arrows 94, 94).
Positioning is performed in the direction (95 directions), and the vertical vice piece 304 is closed and fixed in this state. As shown in FIG. 13B, an indication line 302 is formed on the positioning contact piece 301,
The position is aligned with the black line 303 applied to the wood W1 in advance, and the position is adjusted in the horizontal direction (the directions of arrows 92 and 93).

[0011] Further, when performing the joint processing, the side surface of the wood W2 is brought into contact with the positioning contact piece 301 to be positioned, and in this state, the horizontal vice piece is closed and fixed. In this case as well, a black line is applied to the wood W2 in advance, and the black line and the instruction line 302 formed on the positioning contact piece 301 are aligned.

Further, as a conventional example for adjusting the position of wood, there is the following processing machine. FIGS. 14A and 14B show a configuration for positioning the wood W1 in the case of performing woodcut processing. An indication line 320 is formed on the upper surface 325 of the vertical vise piece 314. And the ink line 32 applied to the wood W1
1 is aligned with the indication line 320, and in this state, the vertical vise piece 314 is closed and the wood W1 is fixed.

In the configuration shown in FIG.
In order to position the wood W1 on the basis of the above, the positional relationship between the instruction line 320 and the cutter 83 needs to be accurately adjusted in advance. When adjusting the positional relationship between the instruction line 320 and the cutter 83, the entire vertical vise device, that is,
The position of the vertical vise piece 314 itself is moved in the directions of arrows 94 and 95.

FIG. 15 shows a configuration for positioning the wood W2 when performing the joint processing. In this case, the wood W2 is positioned using the jig 322. A jig reference line 323 is formed at the center of the jig 322.
Is fixed between the vertical vise pieces 314. And
The black line 326 applied to the wood W2 is aligned with the jig reference line 323, the horizontal vice piece 315 is closed, and the wood W2 is fixed.

[0015]

However, the above-mentioned conventional joint processing machine has the following problems. First, FIGS. 12 and 13
The connection processing machine shown in FIG.
In order to position W2, a positioning contact piece 301 is provided below the mounting base 72. Therefore, there is a problem that the number of parts of the processing machine increases, the configuration becomes complicated, and the price of the processing machine increases.

On the other hand, in the processing machine shown in FIG.
It is only necessary to form the indication line 320 on the upper surface 325 of the vertical vise piece 314, and there is no problem that the number of parts increases. However, this processing machine has the following problems.

As shown in FIG. 14A, the upper surface of the wood W2 on which the black line 321 is provided is aligned with the upper surface 32 of the vertical vise piece 314.
When it is close to 5, the alignment between the instruction line 320 and the blackened line 321 is relatively easy. However, as shown in FIG. 14B, when the upper surface of the wood W <b> 1 is lower than the upper surface 325 of the vertical vise piece 314 and descends, there is a problem that it is difficult to align the instruction line 320 and the black line 321.

Further, in positioning the wood W2 in the case of the joint processing shown in FIG. 15, it is necessary to set the jig 322 on the vertical vise piece 314 and remove it after the wood W2 is aligned. For this reason, there is a problem that work is troublesome and the work efficiency is reduced.

Further, when adjusting the positional relationship between the instruction line 320 and the cutter 83 shown in FIG. 14, the position of the entire vertical vise device, that is, the position of the vertical vise piece 314 itself is indicated by an arrow 9.
4. Move in 95 directions. For this reason, for example, when finely adjusting the position of the cutter 83 and the instruction line 320, there is a possibility that the vertical degree vise device may be moved, thereby causing a degree of parallelism with respect to the cutter 83.
It is difficult to make accurate alignment. For this reason, it is necessary to adjust the position of the entire vertical vise apparatus by using a dedicated jig, so that there is a problem that the work is troublesome and the working efficiency is reduced.

Accordingly, the present invention provides a vice for a processing machine which can easily and accurately position a target member such as wood with a simple configuration and which does not cause a curl in parallelism with a cutting blade such as a cutter. The purpose is to provide the device.
