[Problems to be solved by the invention] However, in the conventional woodworking jig mentioned above, the left and right sides have different hands, so after cutting the mortise on one side, it is difficult to cut the mortise on the other side. In order to machine a mortise in a symmetrical position, it is necessary to adjust the opening 101 with the partition frame 104 again, and in addition to the fact that it must have the same dimensions as the other one, the cutting process is difficult. It was extremely time-consuming.

In particular, in the case of a mortise or the like having an inclined surface for hanging, rather than a simple mortise, the opening 101
Adjusting the dimensions took a lot of effort.

[Means for solving the problem] The purpose of this invention is to solve the above-mentioned drawbacks of the conventional example. A pair of openings are bored at a predetermined interval in the opening, and a first partition plate is slidably attached in between to adjust the width of both openings, and to adjust the width of both openings. It is an object of the present invention to provide a woodworking jig in which a second partition plate is slidably attached to the opening and the length of both openings is adjusted.

[Function] In other words, the woodworking jig of this invention is capable of cutting without punching through, and by adjusting the opening for machining a symmetrical mortise at the same time, it can be accurately and Cutting of mortises etc. can be performed quickly.

[Example] An example of the woodworking jig of the present invention will be described below based on the drawings. In Figures 1 and 5, 1
is a workpiece to be cut, and is detachably attached to the woodworking jig by a clamping means provided on the underside of the woodworking jig. A predetermined cutting range of the attached workpiece 1 is defined by a woodworking jig, and a mortise or the like is formed by a cutting tool such as a trimmer.

The woodworking jig consists of a base frame 2 in which a pair of openings 3, 3' are bored at a predetermined interval on the top surface, both openings 3,
3', a first partition plate 4 attached slidably in the direction of each opening 3, 3', and a first partition plate 4 attached at the longitudinal end of both openings 3, 3' It is composed of a second partition plate 5 attached so as to be slidable in the right angle direction. Both openings 3 and 3' are arranged so that their widths are adjusted by a first partition plate 4 and their lengths are adjusted by a second partition plate 5.

More specifically, a pair of parallel grooves 6 and 6' are formed on the upper surface of the base frame 2 at a predetermined interval, and openings 3 and 3' are formed in each groove 6 and 6'. be. The second partition plate 5 is slidably attached within the grooves 6, 6' and defines the lengths of the openings 3, 3'. The second partition plate 5 is disposed within the grooves 6, 6' so as to be flush with the upper surface of the base frame 2. 7 is a thumbscrew for fixing the first partition plate 4;
8 is a thumbscrew for fixing the second partition plate 5.

In the figure, the first partition plate 4 is a base plate 10 that is slidably attached to approximately the center of the base frame 2.
It consists of a pair of partition members 11 and 12 rotatably mounted on the substrate 10 at a predetermined interval. Each partition member 11, 12 has both openings 3,
It is made of a thin plate having an outer edge defining an arc 3' and an arcuate inner edge, and is rotatably mounted on the substrate 10. Each partition member is provided with an arcuate hole 13 along the inner edge of the arc, and the arcuate holes 13 can be overlapped and fixed to the substrate 10.

A set screw 14 provided upright on the board 10 is inserted into the arcuate hole 13, and is slid in the slide hole 15 to hold the partition members 11, 12 in a predetermined position.
After being rotated to a predetermined angle, it is fixed with the thumb screw 7. Therefore, machining of a mortise having an inclined surface such as a droplet can be easily performed.

The above-mentioned clamping means includes a vertical frame 21 fixedly provided via a spacer 24 opposite both side edges of the lower surface of the base frame 2.
The object 1 to be cut, such as a column, is fitted between the parallel vertical frames 21. A sliding window 22 is formed on one side of the vertical frame 21, and a clamping tool 23 is fitted into the vertical frame 21 at right angles so as to be freely movable toward the side surface of the object to be cut 1.

The clamping tool 23 includes an outer cylinder 31 fitted into the sliding window 22 of the vertical frame 21, and a screw screw 33 housed in the outer cylinder 31 and having a grip 32 attached to one end.
It is composed of a bar 34 that can be retracted and retracted from the tip of the outer cylinder 31 by means of the screw screw 33, and a fixed frame 35 having a U-shaped cross section and attached to the tip of the bar 34 in parallel with the object to be cut 1. . When the grip 32 is turned, the bar 34 advances on the screw screw 33 and extends from the tip of the outer cylinder 31, and the fixed frame 35 comes into contact with and presses the side surface of the workpiece 1.

The outer cylinder 31 has recessed holes 36 at predetermined intervals on the side surface.
A stopper 37 attached to the vertical frame 21 and urged in the direction of the recessed hole 36 is fitted into the recessed hole 36 to be fixed in a predetermined position. The stopper 37 has a tip formed with an inclined surface at the rear in the direction of movement of the outer tube 31, and the outer tube 31 pushes back the tip of the stopper 37 with the rear wall of the concave hole 36 while moving the slide window 22 towards the workpiece 1. Slide quickly inside. In this way, the outer cylinder 31 is roughly moved to a predetermined position, and then the grip 32 is turned to make fine adjustments.

Note that the first partition plate 4 defining both openings 3, 3' and the pair of opposing second partition plates 5,
On one side of the remaining base frame 2, a protrusion 16 having a predetermined width is formed at the lower part. That is, the cutting position, which could not be determined accurately due to the washer 19 located around the blade 18 of the cutting tool 17, can be accurately determined by protruding the protrusion 16 to a position where it almost touches the blade 18. It's summery. 20 is a scale.

When using the woodworking jig of this invention, the woodworking jig of this invention is attached to a pillar so that it is sandwiched by the vertical frame 21, and the pillar is firmly clamped by the clamping tools 23. After that, the shell or the like to be attached is directly fitted into the opening 3 located at the upper part, and the first and second partition plates 4 and 5 are fixed in the position where they abut against the shell 62. After removing the shell 62, the opening 3 is cut using a cutting tool, the woodworking jig is removed from the pillar, and the woodworking jig is turned over and attached to the opposite pillar. In this case, cutting is performed using the opening 3' located above the turned opening 3.

Therefore, the mortise 64 with different handles is connected to the opening 3,
Using 3', without making any individual adjustments,
Moreover, the necessary cutting can be performed without removing the penetration. Further, by rotating the partition members 11 and 12 of the partition plate 4, the openings 3 and 3' can be made to have an inclination that matches the mortise 54 for the drop hook 52 and the stile 53. In this case, the partition members 11 and 12 of the partition plate 4 are fixed with their angles symmetrical, and are adapted to match the mortises 54 located at symmetrical positions on the opposing columns.

The large engraving shown in FIG. 9 can be easily carried out by detachably attaching a U-shaped attachment corresponding to the middle groove to the first partition plate 4.

[Effects of the Invention] Since the woodworking jig of this invention is configured as described above, it is possible to perform cutting without cutting through the hole, and even when the handles are different, one opening 3
After the machining of one mortise is completed, the other mortise at the symmetrical position can be precisely and easily cut using the other opening 3'.

In addition, in the case of not just a simple mortise but also a mortise with an inclined surface for hanging, the opening 3,
By tilting the first partition plate 4 with respect to 3', cutting can be performed with almost no effort.

In other words, the woodworking jig of this invention is capable of cutting without punching through, and can be accurately cut by adjusting the openings 3 and 3' for machining symmetrical mortises at the same time. Moreover, cutting work such as a mortise can be performed quickly.
