Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a planer stand correction device for correcting the smooth surface of a planer stand,
In particular, since the grinding band on the protrusion side and the grinding band on the bottom side are glued in parallel to the smooth upper surface of the base with the right-angled inner surface of the guide plate as a reference, it is possible to quickly and easily correct the smoothness of the smooth surface of the planer stand. The present invention relates to a tool that can quickly and easily modify the flank face on the protrusion side and the butt side of the smooth surface of the planer stock.

[Conventional technology and its problems]

It goes without saying that a plane plane that finishes wood with a smooth surface has a smooth surface C on its plane stand a, as shown in Figure 5.
If the entire smooth surface of the planer stand is a uniform smooth surface, as the finished surface of the wood becomes smooth, the adhesion of the smooth surface of the planer stand to the finished surface of the wood increases, and as a result, the smooth surface of the planer stand increases. Otherwise, the slippage will be poor and the plane blade will not be able to obtain an appropriate cutting speed, resulting in a deterioration in the smoothness of the finished surface and a decrease in work efficiency.

Therefore, in order to prevent the smooth surface of the planer stock from adhering to the finished surface and improve the smoothness, the smooth surface of the planer stock has smooth surfaces C and C near the cutting edge b and near the butt, as shown in Figure 6. ′, and slight flanks a and d are formed on the protrusion side from the protrusion to the vicinity of the blade mouth, and on the butt part side from the vicinity of the blade mouth to the vicinity of the butt, but on the other hand, the blade The smooth surfaces of the planer stock near the mouth and near the butt are prone to wear, and the flanks formed on the protrusion and butt sides are minute, so it is difficult to prevent slight wear on the smooth surfaces of the planer stock. It is necessary to correct the flank face each time, and it is also necessary to correct uneven wear of the planer table due to the operator's handling habits.

In the past, correction of the smooth and flank surfaces of the planer stock due to uneven wear of the planer stock smoothing surface was carried out using a resetting plane with a right-angled blade. Correcting the smooth and flank surfaces of a planer stand due to uneven surface wear was considered a special skill of carpenters, and was considered difficult for do-it-yourself carpenters at home or in woodworking lessons at schools. In other words, the smooth surfaces near the cutting edge and near the butt of the planer stock smooth surface, and the flanks on the protrusion and butt sides, are all formed as independent surfaces, and these four faces are formed at right angles. Make corrections to each side using a plane to correct uneven wear on the smooth surface of the blade near the blade mouth and near the butt, and correct the uneven wear on the smooth surface of the planer to the same smooth surface on the protrusion side and the butt. There is a problem in that it is a difficult technique and takes a lot of time to minutely form each flank face with the side by cutting in a direction perpendicular to the wood grain.

[Purpose of the invention]

The present invention solves the above-mentioned problems of the prior art, and uses the right-angled inner surface of the guide plate protruding from one side of the smooth upper surface of the base as a reference to grind the protrusion side grinding band and the butt side grinding band. By gluing the plates parallel to each other, the reference surface, which is the right-angled inner surface of the guide plate, is used as a guide for the side surface of the planer stand, and the area near the cutting edge of the smooth surface of the planer stand and the stand. By simultaneously grinding both the smooth surfaces near the butt, it is possible to quickly and easily correct the smoothness of the smooth surface of the planer stock, and also to use the reference surface, which is the right-angled inner surface of the guide plate, as a guide for the rising surface of the planer stock. It is an object of the present invention to provide a planer stock correction device capable of quickly and easily correcting the flank surface of a planer stock smooth surface by simultaneously grinding both flanks on the protrusion side and the butt end side of the surface. It is.

[Means to achieve the purpose]

In order to achieve the above object, in the planer stand correction device of the present invention, a guide plate having a right-angled inner surface is provided upwardly protruding from at least one part of the base having a smooth upper surface, and a guide plate is provided on the smooth upper surface of the base. The large head side with a width extending from the prominence of the smooth surface of the planer stock to the vicinity of the blade tip = 4- The grinding band on the butt side side with a width extending from the vicinity of the blade tip to the vicinity of the butt end are glued in parallel. It is what is being worn.

[Effect]

In the planer head correction device configured as described above, the grinding band on the protrusion side and the grinding band on the butt side are parallel to each other with reference to the right-angled inner surface of the guide plate protruding from one side of the smooth upper surface of the base. Since the plate is glued in a shape, by contacting the side surface of the planer head with the reference surface, which is the right-angled inner surface of the guide plate, and using the grinding band on the protrusion side, it is possible to slide the planer stand using the right-angled inner surface of the guide plate as a guide. By moving the slider, both the smooth surfaces near the cutting edge and near the butt of the planer stock smooth surface can be simultaneously ground, and uneven wear on the planer stock smooth surface can be corrected all at once to the same proper smooth surface.

In addition, by abutting the rising surface of the planer stand against the reference surface, which is the right-angled inner surface of the guide plate, and using the grinding band on the rise side and the grinding band on the bottom side, the planer stand can be slid using the right-angled inner surface of the guide plate as a guide. By doing so, it is possible to simultaneously grind both the relief surfaces on the protrusion side and the butt side of the planer stock smooth surface, and to correct the same appropriate flank surfaces all at once.

〔Example〕

The embodiment will be described with reference to the drawings. Reference numeral 1 designates the base of the plane table correction device. Guide plates 2 and 2' having right-angled inner surfaces 3 and 3' that are perpendicular to the upper surface of the base 1 and smooth upper surfaces 4 and 4' are provided on both sides and project upward from the upper surface of the base 1, preferably. is formed slightly lower than the height of the planer stand. Further, on the smooth upper surface of the base 1, there is a protrusion side grinding band 5 having a width extending from the protrusion of the planer stock smooth surface to the vicinity of the cutting edge with reference to the right-angled inner surface 3 of the guide plate 2 protruding from one side; The butt side grinding belt 6, which has a width extending from the vicinity of the blade mouth to the butt part, is glued in parallel, and the distance between the protrusion part side grinding band 5 and the butt part side grinding band 6 is the same as that of the plane head. It coincides with the smooth surface formed from the cutting edge to the butt side, and the butt end of the butt side grinding band 6 corresponds to the raised side of the smooth surface formed near the butt of the planer stock. Both of these are related to the size of the smooth surface formed near the cutting edge and near the butt of the planer stand, but the size of this smooth surface is determined by the operator's empirical rules. Therefore, in the embodiment, economy is achieved by using the grinding band 5 on the protrusion side and the grinding band 6 on the bottom side having the same width. However, both grinding bands 5 and 6 are glued to the smooth upper surface of the base 1, and can be easily replaced by peeling. It is possible to use the grinding band 5 and the butt side grinding band 6 having different widths.

Note that m7 are integrally formed on the lower surface of the base 1 near the four corners, and the legs 7 are made of a material with a large friction coefficient, such as rubber, to stabilize the base 1 when modifying the plane stand. I support it.

〔Effect of the invention〕

The present invention is constructed as described above, and the grinding band on the protruding part side and the grinding band on the butt part side are set on the basis of the right-angled inner surface of the guide plate protruding from one side of the smooth upper surface of the base. Since the grinding band is glued in parallel, the reference surface, which is the right-angled inner surface of the guide plate, is used as a guide for the side surface of the planer stock, and both the smooth surfaces near the cutting edge and near the butt of the planer stock smooth surface are used. By grinding at the same time, the smoothness of the smooth surface of the planer stock can be corrected, and the reference surface, which is the right-angled inner surface of the guide plate, can be used as a guide for the rising surface of the planer stock, and the smooth surface of the planer stock smooth surface is By grinding both flanks at the same time, it is possible to correct the flanks of the smooth surface of the planer stand, so when resetting the plane, there is no need to use a right-angled blade resetting plane, which was previously considered difficult, and it is easy to do at home as a do-it-yourself tool. It also allows for quick and easy resetting of planes in woodworking lessons at schools.
