Description

[Detailed explanation of the invention] This invention is related to a plane body for woodworking.
In particular, the fishing force is made of a disposable thin steel plate, and the blade attachment is structured accordingly.

As shown in Figure 6, the plane body of the woodworking nameplate is located in the cut groove C formed in a part of the plurality of concave grooves provided on the circumference of the cylindrical plane body main body A. It is formed by fitting a plate-like fishing force into it and tightly fixing the block metal fitting called a back seat to a pressure bolt.

In this case, the above fishing force 2 has a width of 25 to 49 mm and a thickness of 3
~5.5mm, length is 200~6 depending on machine size
It is a plate-shaped body with a diameter of 0.00 mm and is used by re-sharpening the cutting edge until it wears out.As the fishing force decreases in width due to re-sharpening, when installing it on the plane body, There is a disadvantage that it requires time and effort to adjust the cutting edge each time.

In contrast, this idea makes the fishing force made of a thin steel plate and makes it disposable, and the block metal fitting that is the back seat is used as a blade attachment to accommodate this, so that the main body of the conventional planer body can be used as is. An embodiment of this invention will be explained with reference to the drawings. In Fig. 1, 1 is the main body of the plane, 2 is a concave groove, and 3 is a cutting groove, which are the same as the conventional device described above. It is.

Inside this groove 2, there is a blade mounting tool 4 which corresponds to the conventional back seat, and a blade abutment plate 5 which is a strip-shaped blade instead of the conventional plate-shaped fishing force.
are fitted, and a thin plate-shaped fishing force 6 is held and held between them.

This fishing force 6 is for disposable use, and as shown in Fig. 2, a cutting blade 7 is attached to one end edge along the longitudinal direction of a strip-shaped thin steel plate with a thickness of 0.5 to 2.0 mm and a width of 6 to 15 mm. There are also horizontally long mounting holes 8 at predetermined intervals in the central part.
is the provision.

The blade mount 4 is made of a square bar with a trapezoidal cross section, and the upper half of the front surface thereof is shaved to form a blade mount surface 10 that is continuous with the support step 9, and the upper edge of the blade mount surface 10. 11 is made of wear-resistant material by partially hardening or joining wear-resistant steel.

As is clear from FIG. 3, stepped round holes 12 and press bolt screw holes 13 are alternately provided at predetermined intervals in this blade mount 4. Stepped round hole 12
A fixing metal fitting 14 in the shape of two short circular rods, large and small, that fit into this round hole is fitted into the bottom surface 1 of the blade mount 4.
A bolt 17 is inserted through a bolt hole 16 provided in the fixing member 14, and its tip is screwed into a screw hole 18 provided vertically in the fixing metal fitting 14, and the bolt 17 is tightened and fixed.

In addition, press bolts 19 of a slightly larger diameter are screwed into the expansion bolt screw holes 13, and are expanded to attach the blade attachment 4 with the fishing force 6 to the blade abutment plate 5. It's like it's being forced.

The blade abutting plate 5 is used to evenly press the fishing force 6 against the blade mount 4, and one side of the blade abutment plate 5 is shaved to form four shallow parts 2.
0 is set.

As shown in FIG. 6, which will be described later, this blade abutment plate 5 is not necessarily necessary. Due to the above-described structure, the fishing force 6 is provided by a fixing fitting 14 that is lowered down through a bolt 17 on the front surface of the blade mount 4. The lower edge is press-contacted to the stepped portion 9 through the blade attachment plate 5, and the blade attachment 4 is connected to the pressure-contact bolt 19.
It is press-fitted and fixed in the groove 2 together with the blade abutting plate 5.

The fishing force 6 is such that the height of the cutting edge is naturally adjusted via the support step 9, and because it is a thin steel plate, after it wears out,
It would be a shame to throw it away immediately.

Next, FIG. 4 shows another example of this invention.

That is, in this case, the fishing force 6' has cutting blades 7', 7' formed on both edges along the longitudinal direction, and a mounting hole 8' consisting of a long hole in the middle uses the other cutting blade 7'. , can be used twice.

Further, the supporting step portion 9' of the blade attachment 4' is formed into an acute-angled cut shape to support the cutting edge 7' of the fishing force 6' without damaging the cutting edge.

Other parts are the same as those in the previous embodiment and are designated by the same reference numerals as in FIG.

Next, FIG. 5 shows still another modification of this invention.

That is, in this case, the fishing force 6'' has cutting blades 7'', 7'' on both ends like the one in FIG. 4, but instead of providing a series of steps on the blade attachment 4''. A support stepped portion 9'' made of a reference pin whose upper surface has been shaved and flattened is installed horizontally at a predetermined position in advance, and the fishing force 6'' uses every other mounting hole 8'' of the reference pin as the support stepped portion of the reference pin. 9", and the other every other one is pushed down by the fixing fittings 14 inserted into the stepped round holes 12 in the same way as described above, and is superimposed and fixed to the blade mounting tool 4".

FIG. 6A is an explanatory diagram in which the blade abutment plate 5 used in the embodiment (FIG. 1) is omitted.

After the fishing force 6 is attached to the blade mount 4, it is directly pressed and fixed to the side wall of the groove 2 of the main body 1 of the plane with a pressure bolt 19 along with the blade mount.

FIG. 6B is an explanatory view of a modified example in which the shape of the groove 2 of the main body 1 of the plane and the tightening method of the back seat are different from those of the previous embodiment.

The recessed groove 2' is made of iron film parallel to the outer periphery of the main body of the plane, and the blade attachment 4' fitted into this recessed groove 2' is formed in the shape of a square bar with a rectangular cross section, and is fitted with a pressure bolt. 19'...
. . . is screwed into a screw hole 22 . . . which is threaded from the outer periphery of the main body 1 ′ of the plane to the groove 2 ′. A support recess 21 for abutting the pressure bolt is provided at a position corresponding to . It is press-fitted integrally into the concave groove 2' of the main body 1' of the cutter body 1' by means of pressure-welding pins 19' screwed into the main body 1'.

The other parts are formed in the same configuration as the previous embodiments (FIGS. 1 and 6A).

As mentioned above, this invention has a fishing force of 6, 6', 6"
It is made inexpensively from thin steel plate and disposable, and it is extremely easy to install and securely fixed, and it is efficient because the conventional plane body can be used as is. It has many advantages.
