Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting edge adjusting device for a plane of a superfinishing plane for woodwork.

[0002]

2. Description of the Related Art A blade having a blade tip projecting from a shaving discharge port formed in a direction substantially orthogonal to a material feeding direction on an installation inclined surface and having a back blade and a plane blade integrated with each other are attached to the installation inclined surface. In a super-finishing plane for woodworking equipped with a plane, the plane blades of the plane must have an appropriate degree of protrusion and be projected in parallel in the left-right direction. Therefore, various blade edge adjusting devices have been proposed.

[0003]

As the blade edge adjusting device, as in Japanese Utility Model Publication No. 61-21201, adjusting screws are provided at both ends of a plane blade, and a collar provided at the end of the adjusting screw is used as a frame. There has been proposed a configuration in which the edges of the blades are engaged with each other, and when adjusting the blade edges, the plane is taken out and the left and right adjusting screws are respectively rotated. However, in the structure according to the above, adjustment cannot be performed by the parallel movement of the cutting edge, and further,
It was troublesome to take out the plane.

[0004] On the other hand, as the one capable of adjusting the cutting edge by the parallel movement of the cutting edge while the plane is still attached to the super-finishing plane, there are No. 55-160801 and No. 56-4.
There is No. 8606. In this configuration, the parallel movement of the cutting edge can be performed while the plane is attached to the super-finishing plane, but the horizontal adjustment of the blade needs to be taken out from the super-finishing plane and sequentially adjusted.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cutting edge adjusting device capable of easily and smoothly adjusting the degree of protrusion of a cutting edge and the parallelism thereof from the outside of a plane.

[0006]

According to the present invention, a blade tip adjusting shaft is passed across a mounting groove formed in a blade installation inclined surface of a plane in the width direction with its rotating operation portion facing the end of the plane. Two width-moving pieces are screwed into the male screw part formed on the blade tip adjusting shaft so as to be separated from each other in the left-right direction, and further, the width-moving pieces are turned into a tool via a guide mechanism that converts the left-right movement into forward-backward movement. It is linked to a front and rear moving piece that is fixed across the width direction, and a tilt guide piece is provided on one of the width moving pieces, and a guide mechanism that converts the lateral movement of the tilt guide piece into the front and rear movement is provided. The parallelism adjusting shaft is linked to the mounting groove formed on the inclined surface for mounting the blade in the widthwise direction with the turning operation portion thereof facing the end of the plane, and is attached to the male screw portion formed on the parallelism adjusting shaft. The tilting guide piece is screwed on. Incidentally, one of the two width moving pieces is screwed into the male screw portion of the blade tip adjusting shaft and the other is fixed to one width moving piece, or both width moving pieces are respectively screwed to the blade tip adjusting shaft. As a result, they are screwed to the blade tip adjusting shaft.

[0007]

[Operation] When the turning operation portion of the blade tip adjusting shaft facing from the end of the plane is operated to rotate the blade tip adjusting shaft, the left and right width moving pieces are moved along the adjusting shaft by the guiding action of the male screw portion. Along with this, the guide mechanism moves the front-rear moving piece in the front-rear direction. As a result, the blade fixed to the front-back moving piece moves back and forth.

This time, when the turning operation portion of the parallelism adjusting shaft facing from the end of the plane is operated to rotate the parallelism adjusting shaft, the tilting guide piece moves in the width direction in conjunction with this, Along with this, the guide mechanism causes only one of the width moving pieces to move in the front-rear direction by the tilting guide piece. Then, only one side of the back-and-forth moving piece is adjusted back and forth and slightly tilted, so that the parallelism of the cutting edge is adjusted.

[0009]

By applying various adjusting means before mounting, the interlocking shafts 25L and 25R are omitted,
The end of the front-rear moving piece 20 may be directly bolted to the blade 5.

Next, the essential part of the present invention will be described.

As shown in FIGS. 3 to 7, a mounting groove 13a is formed along the width direction on the blade mounting inclined surface 4 of the plane base 1, and a blade tip adjusting shaft 14 is inserted into and supported by the mounting groove 13a. The turning operation portion 14a, which is turned by a hexagon wrench fixed to the end portion, is exposed from the end face of the plane 1 to the outside. As shown in FIG. 6, the blade tip adjusting shaft 14 is composed of a base rod portion 14b having a rotating operation portion 14a and an interlocking rod portion 14c, and a male screw portion 14d formed at the tip of the base rod portion 14b. The width moving piece 15L is screwed to the screw hole, the end of the interlocking rod portion 14c is screwed into the screw hole of the width moving piece 15L, and the width moving piece 15R is fixed to the tip of the interlocking rod portion 14c. That is, the width shifting pieces 15L and 15R are moved by the interlocking rod portion 14c.
Are connected to the male screw portion 14d and screwed integrally with the male screw portion 14d, and the guide action of the male screw portion 14d makes it possible to adjust the movement in the left-right direction as the blade tip adjusting shaft 14 rotates.

It should be noted that the blade tip adjusting shaft 14 may be provided with two male screw portions on the right and left sides, and the width moving pieces 15L and 15R may be respectively screwed into the male screw portions. As shown in FIG. 7, the width-moving piece 15R is restrained from moving in the front-rear direction in the mounting groove 13a.
It can only be moved left and right.

As shown in FIG. 2, the width moving piece 15L has an inclined portion 17 and a cutting edge adjusting shaft 1 projecting from the lower surface thereof.
4 and a sliding ridge 16 parallel to each other. Further, an inclined guide protrusion 18 is formed on the width moving piece 15R.

On the other hand, the front-rear moving piece 20 is provided with a parallel guide hole 21 and an inclined guide hole 22 at its left and right positions. Then, the sliding protrusion 16 of the width moving piece 15L is slidably fitted in the parallel guide hole 21, and the inclined guide protrusion 18 of the width moving piece 15R is also slidably fitted in the inclined guide hole 22. is doing.

Furthermore, the inclined portion 17 of the width moving piece 15L
Is fitted into the tilt guide hole 33 of the tilt guide piece 32, as shown in FIGS. The tilt guide piece 32 has a rectangular peripheral shape, and is formed with a linking projection 35 having a screw hole 34 formed at the rear end thereof. Further, in the center thereof, communication holes 36, 3 through which the cutting edge adjusting shaft 14 penetrates
6 is formed in communication with the inclined guide hole 33. Further, as shown in FIG. 7, the tilt guide piece 32 is attached to the mounting groove 13
The movement in the front-rear direction is restrained within a, and the movement is possible only in the left-right direction.

As a result, when the width moving piece 15L moves in the width direction, the inclined portion 17 moves in the tilt guide hole 33 of the tilt guide piece 32, and the width moving piece 15L is displaced in the front-rear direction. Further, since the sliding protrusion 16 is fitted in the parallel guide hole 21 and is coupled to the front-rear moving piece 20 in the front-rear direction, the width-moving piece 15L is attached to the front-rear moving piece 20 by the front-rear displacement of the width-moving piece 15L. Back and forth movement occurs.

When the width-moving piece 15R moves in the width direction, it is guided by the widthwise movement of the inclined guide ridges 18,
The movement is converted into the longitudinal displacement of the longitudinal moving piece 20 in accordance with the inclination angle.

The guide mechanism for converting the lateral movement of the width moving piece 15L into the longitudinal movement of the longitudinal moving piece 20 is as follows.
The guide mechanism constituted by the inclined portion 17 and the inclined guide hole 33, which converts the lateral movement of the width moving piece 15R into the longitudinal movement of the longitudinal movement piece 20, includes a guide ridge 18 and an inclined guide hole 22.
Will be composed of.

On the other hand, the plane 1 has a parallelism adjusting shaft 30.
Is mounted in the mounting groove 13c in the width direction so as to face the rotation operating portion 30a adjacent to the rotation operating portion 14a of the blade tip adjusting shaft 14 at the end of the plane 1. The parallelism adjusting shaft 30 is formed with a screw that is screwed into the screw hole 34 of the tilt guide piece 32. The rotating operation part 30a is operated by a hexagon wrench and has a hexagonal hole. Then, the tilt guide hole 33 of the tilt guide piece 32
In addition, the inclined portion 17 of the width moving piece 15L linked to the blade 5 is
As described later, the lateral movement of the tilt guide hole 33 is converted into the longitudinal movement by the guiding action thereof, which will be described later. A guide mechanism for converting the movement in the front-rear direction of 15 L is configured. That is, the inclined portion 17 and the inclined guide hole 33
Serves as both the guide mechanism for converting the lateral movement of the width moving piece 15L into the longitudinal movement of the longitudinal moving piece 20 and the above-mentioned guiding mechanism.

Next, the blade edge adjusting operation in this structure will be described.

When the entire blade edge is moved in parallel to finely adjust the degree of protrusion, the blade edge adjustment shaft 14 facing from the end of the plane 1 is provided.
The rotation operating part 14a is operated to rotate the base rod part 14b of the cutting edge adjusting shaft 14. Along with this, the width moving piece 15L moves by the guiding action of the male screw portion 14d formed at the end of the base rod portion 14b, and is further connected to the width moving piece 15L via the interlocking rod portion 14c. The width moving piece 15R also follows. That is, the width moving pieces 15L and 15R move in the width direction in proportion to the rotation amount.

By this movement, the width moving piece 15L
The slanted portion 17 moves in the slant guide hole 33 of the tilt guide piece 32, the sliding ridge 16 is fitted in the parallel guide hole 21, and the width moving piece 15L moves forward and backward with the front and rear moving piece 20. Since they are linked, the feed force is generated on one end side of the front-back moving piece 20 due to the front-back movement displacement of the width moving piece 15L. On the other hand, when the width moving piece 15R moves in the width direction, it is guided by the widthwise movement of the inclined guide ridges 18, and the movement is converted into the front-back movement according to the inclination angle, and the front-back movement piece 20. A feed force is generated at the other end of the. As a result, the front-rear moving piece 20 is pushed out at both left and right end portions thereof in parallel with the rotation of the cutting edge adjusting shaft 14, and moves in parallel. Then, nut pieces 23L, 23R are fixed to the front-rear moving pieces 20, respectively, and interlocking shafts 25L, 25R screwed to the nut pieces 23L, 23R.
Since the disc-shaped brim pieces 27, 27 at the tip end of the blade are linked to the blade 5 through the back blade 7, the blade 5 is finely moved in parallel by the forward / backward movement of the forward / backward moving piece 20, and the degree of protrusion of the blade edge is increased. Can be adjusted.

In the width-moving piece 15L and the width-moving piece 15R, the width-moving piece 15L itself moves in the front-back direction as the tilt guide piece 32 moves in the left-right direction. As shown, the blade tip adjusting shaft 14 tilts in the front-back direction by elastic deformation with the width moving piece 15R as a fulcrum portion. At this time, the blade edge adjustment is about 1 mm,
For this reason, the deformation of the blade tip adjusting shaft 14 is minute and does not cause any trouble.

On the other hand, when adjusting the parallelism of the cutting edge,
Rotation operation part 30 of parallelism adjusting shaft 30 facing the end of plane 1
Rotate a. As a result, the screw of the parallelism adjusting shaft 30 is screwed into the screw hole 34 of the tilt guide piece 32, and the feed action thereof causes the tilt guide piece 32 to move in the width direction. Since the tilt guide hole 33 of the tilt guide piece 32 moves in the width direction, the width moving piece 15L in which the tilted portion 17 is fitted in the tilt guide hole 33 moves in the front-back direction due to the guiding action of the tilt guide hole 33. A feeding force is applied, and it slightly moves in that direction.

At this time, as shown in FIG. 7, the width moving piece 1
5R is constrained from moving in the front-rear direction within the mounting groove 13a, so that the front-rear moving piece 20 linked to the width-moving piece 15L and the width-moving piece 15R has a width of the width-moving piece 15R as a fulcrum. One side is slightly sent out by the moving piece 15L and tilts, and following this, the blade 5 fixed to the front-back moving piece 20 via the nut pieces 23L, 23R and the interlocking shafts 25L, 25R also tilts, The parallelism of the cutting edge will be adjusted.

At this time, the width-moving piece 15L and the width-moving piece 15R are screwed onto the cutting edge adjusting shaft 14, but the degree of adjustment thereof is a minute unit of 0.1 mm.
The relative displacement in the front-rear direction of 5 L and the width moving piece 15 R is allowed by elastic deformation of the blade tip adjusting shaft 14 and minute play of the connecting portion.

By rotating the rotary operation part 14a of the blade tip adjusting shaft 14 and the rotary operation part 30a of the parallelism adjusting shaft 30 facing the one end of the plane base 1 with a hexagon wrench, the plane base is moved. It is possible to easily adjust the degree of protrusion and parallelism of the blade edge of the blade 5 without having to remove 1.

[0034]

As described above, according to the present invention, the rotary operation portion 14a of the blade tip adjusting shaft 14 and the rotary operation portion 30a of the parallelism adjusting shaft 30 are provided at the end of the plane 1, and the blade edge is provided. Adjustment shaft 14
The two left and right width-moving pieces 15L and 15R linked to the front-and-rear moving piece 20 are moved in the width direction by the rotation of the. The blade 5 fixed to the front is moved in parallel in the front-rear direction to adjust the degree of protrusion of the blade edge, and the parallelism adjusting shaft 30 is rotated to move the tilt guide piece 32 linked to one width moving piece 15L in the width direction. It moves and converts this into the front-back direction movement of the width movement piece 15L via the guide mechanism, and one side of the front-back movement piece 20 is made to follow this, and the blade 5 is slightly tilted, whereby the degree of protrusion of the cutting edge is increased. Therefore, fine adjustment of the degree of protrusion and parallelism of the blade tip can be optimally performed by rotating the rotating operation portions 14a and 30a without the need to remove the plane 1. 5 is ideal for adjusting the cutting edge, etc. There is an effect.
