Description

[Detailed description of the invention] [Industrial application field] This invention relates to a grooving jig, more specifically, to a grooving jig used for cutting a recessed groove for attaching a hinge to the end face of a door. .

[Conventional technology]

To attach a hinge to the door that serves as a fulcrum for opening and closing, cut a recessed groove on the installation side of the door with a depth and size that fits the hinge plate, and then cut the plate into the recessed groove. is fixed to the door with screws.

Conventionally, the above-mentioned recessed grooves on the mounting side end surface of the door have been formed manually using a cutting tool such as a chisel.

[The problem that the idea attempts to solve]

However, manually forming the recessed grooves has a problem in that the cutting work is time-consuming and requires special cutting techniques.

Therefore, in order to solve the above-mentioned problems, this invention aims to provide a grooving jig that can easily machine grooves into the required shape on the surface of wood without requiring special techniques. There is.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention has a positioning stopper and a clamp that secures the workpiece to be cut with this stopper on the back side of a base plate provided with a window hole, facing each other with the window hole in between. A movable plate is placed on the base plate so that its position can be freely adjusted in the parallel direction of the stopper and the clamp, a tracing hole is provided in the movable plate, and a fixture for the movable plate is provided in the base plate. was adopted.

[Effect]

The profiling hole made in the movable plate overlaps the window hole in the base plate, and the profiling hole is positioned based on the stopper, the movable plate is fixed to the base plate with a fixture, the heath plate is placed on the workpiece, and the stopper and The base plate is fixed to the workpiece by holding the workpiece with a clamp.

When the rotary shaft of a cutting tool with a cutting tool attached to the tip of the rotating shaft is moved along the profiling hole and within the range of the profiling hole, the cutting tool at the tip cuts the surface of the workpiece along the shape of the profiling hole. It can be cut and grooves can be formed.

The lever 9 has its tip connected to the base rod 22 in the swing rod 10.
The other end of the lever 9 is pivotally fixed by a pin 29, and the intermediate part is pivotally fixed to the tip of the link 8 by a pin 30, so that the operating end 31 protrudes to the opposite side of the swinging rod 10, and the lever 9 can be operated. This allows the swinging rod 10 to horizontally rotate around the pin 24.

FIG. 7 shows that the operating end 31 of the lever 9 is connected to the vertical wall 6a.
The state in which the pressing member 27 of the clamp piece 11 is directed toward the stopper 4 and the workpiece A is clamped is shown, and at this time the pins 21, 30, and 29
are arranged in a straight line, and the swinging rod 23 is fixed so as not to rotate.

FIG. 8 shows a state in which the workpiece A is released from the grip. When the operating end 31 is pulled to the side opposite to the vertical wall 6a of the L-shaped plate 6 from the state shown in FIG. 29, pull the tip of the link 8 with the pin 30 in the middle, and the link 8
The lever 9 rotates around the pin 21, and as a result, the lever 9 moves toward the operating end 31, and the pin 29 at the tip pulls the swinging rod 10 in the same direction.
The clamp piece 11 is separated from the workpiece A.

In this way, the clamp 5 can quickly clamp and release the workpiece A by operating the lever 9.

Movable plate 1 placed on the base plate 1
2 has a tracing hole 13 smaller than the window hole 3 in its center.
is provided, and a rising wall 2 is provided between the rising walls 2 and 2.
A fixing device 14 using a tightening screw is attached to one rising wall 2 of the base plate 1 to press and fix the movable plate 12 against the other rising wall 2. .

Note that the planar size and shape of the tracing hole 13 used in the movable plate 12 are set to correspond to the size of the attachment member to the workpiece A, and therefore, the vertical movable plate is prepared according to the type of attachment member. be done.

In addition, the cutting tool (trimmer) has a cutting tool 16 that can cut the tip and peripheral surface attached to the tip of a rotating shaft 15 driven by the motor of the main body, and a profiling hole 13 is imprinted in the middle of the rotating shaft 15. Sleeve 1 for
7, and the depth of cutting is made at the portion of the main body that abuts on the movable plate 12.

Furthermore, in order to accurately set the amount of remaining cutting from the contact surface to the stopper 4 during cutting, a fourth
As shown in the figure, base plate 1 or movable plate 12
It is convenient to provide a scale 18 on either side of the movable plate 12 for reading the fixed position of the movable plate 12.

That is, in FIG. 4, the dimension C from the stopper fixed side edge 1a of the base plate 1 to the receiving surface of the cut object A of the stopper 4, and the dimension C of the profiling hole 13 provided in the movable plate 12 located closer to the stopper 4. The dimension D from the edge of the circumference to the edge 12a located on the same side of the movable plate 12 is set equal, and a scale 18 starting from the edge 1a of the base plate 1 is set on the base plate 1 to measure the length of the wall 2. Provided along the direction.

The movable plate 12 placed on the base plate 1 is
On the other hand, the position of the tracing hole 13 is set by sliding the rising wall 2 along the length direction of the rising wall 2, and the movable plate 12 stacked on the base plate 1 covers the scale 18. become.

When positioning the tracing hole 13 of the movable plate 12,
The position of the movable plate 12 is determined by reading the scale 18 on the part exposed from the movable plate 12 so that the dimension E from the edge 1a of the base plate 1 to the edge 12a of the movable plate 12 is the required amount of uncut material. the movable plate 1 by screwing the fixture 14 in this state and pressing the movable plate 12 against the other rising wall 2.
2 to the base plate 1.

In this state, by setting the dimensions of each part as described above, from the edge 1a of the base plate 1 to the movable plate 1.
Since the dimension E up to the edge 12a of 2 always matches the uncut amount dimension F from the receiving surface of the stopper 4 to the edge of the profiling hole 13, the uncut amount can be set accurately using the scale 18. become.

The grooving jig of this invention has the above-mentioned configuration, in which the movable plate 12 having a profiling hole 13 of a desired shape is selected and placed on the base plate 1, and the position of the profiling hole 13 relative to the stopper 4 is adjusted by adjusting the position of the profiling hole 13 against the stopper 4. 2 along the length direction, and tighten the fixture 14 with the tracing hole 13 positioned above the window hole 3 to fix the movable plate 12 to the base plate 1.

In this state, place the base plate 1 on the wooden workpiece A.
3, operate the clamp 5 in the tightening direction with the profiling hole 13 corresponding to the cutting position, and as shown in FIG.
, and fix the base plate 1 on the workpiece A.

Next, insert the blade 16 attached to the cutting tool into the profiling hole 1.
3 into window hole 3, and copy sleeve 17 through hole 1.
When the cutter 16 is rotated and moved while in contact with the peripheral edge of the profiling hole 13, and further moved within the profiling hole 13, the cutter 16 corresponds to the profiling hole 13 as shown in FIGS. 2 and 6. It is possible to cut the recessed groove B in the shape shown in FIG.

Note that the object to be cut A is a wooden product such as a door,
The recessed groove B becomes a part into which the plate of the hinge is fitted and fixed with screws.

〔effect〕

As described above, according to this invention, positioning stoppers and clamps are installed on the back side of the base plate with the window hole on both sides of the window hole, and a tracing hole is provided on the movable plate placed on the base plate. ,
Since the base plate is equipped with a movable plate fixing device for the base plate, by moving the rotary blade within the profiling hole while the base plate is fixed to the wooden object to be cut, a recessed groove that matches the shape of the profiling hole can be cut. By selecting the shape of the profiling hole, a recessed groove of the required shape can be easily and efficiently machined without requiring special techniques.
