Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric planer, and more particularly to an electric planer having a chip guide section on the front base.

The front base portion of a conventional electric planer will be explained with reference to FIGS. 1 and 2. Figure 1 is a longitudinal sectional view of the front base including the cutter block, and Figure 2 is a partial view to explain the blade height adjustment work. 1 is the blade, 2 is the chip guide, and 3 is the front base. Bottom part, 4 is the cutting edge for cutting operation by the blade 1, 5 is the presser foot of the blade 1, 6 is its fixing bolt, 7 is the rear base, 8 is the bottom of the rear base 7, 9 is the blade height adjustment of the blade ruler, 10 is screwdriver 11
16 is a cutter block, 20 is the main body of the electric planer, and blade 1
The chip guide part 2 and the bottom part 3 for guiding the chips cut by the blade are integrated, and since the chip guide part 2 protrudes toward the blade 1 side, the cutting edge 4 is narrow and tapered. , it is not easy to attach or detach the blade 1, presser metal 5, bolt 6, etc., and to adjust the blade height of the blade 1, press a ruler 9 against the bottom surface 8 of the rear base 7 as shown in FIG. Since the structure requires inserting the screwdriver 11 through the diagonal hole 10 of the blade, it is difficult to do so, especially when adjusting the blade height.
Since the bolts 6 are located below the rear base 7, they are difficult to see and workability is poor.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electric planer that eliminates the above-mentioned drawbacks and allows easy attachment and detachment of the blade and adjustment of the blade height.

The present invention provides an electric planer equipped with a front base having a chip guide for discharging chips cut by a blade, in which the front base has a chip guide and a bottom forming portion of the front base. It is characterized by having a structure that includes an integral molded member and that the molded member is movable in the front and rear direction.

Hereinafter, embodiments of the present invention will be described based on the drawings. 3 to 6 are drawings for explaining one embodiment of the electric planer of the present invention, and FIG. 3 is a longitudinal sectional view of the front base portion including the cutter block;
Fig. 4 is a bottom view of Fig. 3, Fig. 5 is a partial view for explaining the blade height adjustment work, and Fig. 6 shows another installation state of the integrally molded member forming the bottom surface of the front base. FIG. 3 is a bottom view of the front base portion. In these figures, Figures 1 and 2
Identical parts or parts that act in the same way as in the figures are given the same reference numerals. The difference from conventional electric planers is that the front base includes a base plate 12, which is a molded member that integrates the chip guide and the bottom surface forming part of the front base, and this base plate 12 is movable in the front and back direction. It has a structure provided on the bottom part 3 of the front base 13, and 14 is the base plate 1.
2 is a set screw in the elongated hole 15, 17 is a protrusion provided on the ruler 9 to determine its relative position with the rear base 7, and 18 is a projection that similarly sets the height of the blade 1 to the dimension l. 19 is a blade mounting surface, and 21 is a protrusion provided on the bottom surface 3 of the front base 13 so as to engage with the elongated hole 15.

That is, in this embodiment, when removing the blade 1 for replacement or polishing, the set screw 14 is loosened, the base plate 12 is moved forward, and the blade mouth 4 is opened wide by temporarily fixing it with the set screw 14. It is easy to operate because it can be maintained in the same condition. In this way, the cutter block 16 is fixed at a position where the blade mounting surface 19 of the cutter block 16 is parallel to the bottom surface 8 of the rear base 7, and the bolt 6 is loosened to remove the presser foot 5 and the blade 1. When attaching the blade 1 and adjusting the height of the blade, the cutter block 16 is kept in a similar state. blade 1
After installing, temporarily tighten the setscrew 14.
Loosen and move the base plate 12 backward,
By tightening the setscrews 14, the base plate 12 can be easily set to its normal state.

FIG. 6 shows a structure in which a protrusion 21 is engaged with one of two elongated holes 15 provided in the base plate 12, and the other is fixed with a set screw 14. In this case, other setscrews may be used to firmly fix the base plate 12 around it.

As explained above, the electric planer of the present invention is
Since the blade opening from which the chip guide protrudes can be opened wide, it is a practical tool that allows you to easily and reliably attach and detach the blade installed on the cutter block and adjust the blade height. It can be effective.
