Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a planer. More specifically, the side alignment and chamfering of an object to be cut are performed by one through groove formed on the bottom surface of a plane. Regarding Kanna who made it possible.

<Prior Art> Conventionally, as shown in FIG. 6, a planer having a through groove having a substantially V-shaped cross section and a through groove having a substantially U-shaped cross section formed side by side in the longitudinal direction of the bottom surface of a plane has been devised and put on the market. ing.

The above-mentioned planer is convenient because it is capable of chamfering and side-by-side cutting of the object to be cut with one planer.

<Problems to be solved by the invention> However, in the above-mentioned planer, even when the same surface of the object to be cut is aligned and chamfered, the cutting surface of the object to be cut should be in contact with the U-shaped groove. After contacting and operating the plane to perform side alignment, it is necessary to change the cutting surface of the object into the V-shaped groove and bring it into contact, and operate the plane to perform chamfering. Replacing into the groove was troublesome.

This invention overcomes the above-mentioned difficulties in the work of the conventional planer and is an improvement, and the side-by-side alignment and chamfering of the cutting object is performed on the bottom surface of the plane without the need to replace the groove. The purpose is to provide a planer that can be formed by one formed through groove.

<Means for Solving the Problems> The configuration of the planer of the present invention for solving the above problems is as follows.
It is a planer that presses the object to be cut against the bottom surface of the groove formed through the longitudinal direction of the bottom surface of the plane and cuts the object with the plane blade protruding from the top surface of the plane to the both sides of the groove. On one of the plane stand side walls, a contact surface for side-by-side cutting of objects to be cut that is vertically raised from the groove bottom surface is formed, and on the other plane side wall, an obtuse angle from the bottom side of the groove is formed. A chamfering contact surface of the object to be cut is formed so that the groove gradually widens toward the opening side. The point lies in that an auxiliary surface for chamfering is formed to be brought into contact with the object to be cut along the contact surface.

<Operation> According to the present invention having the above-mentioned configuration, when the objects are to be aligned, the object to be cut is placed on the side surfaces of the planes at both ends of the groove which are vertically raised from the groove bottom surface. Along
By pressing the cutting surface on which the objects to be aligned are pressed against the bottom surface of the groove and operating the planer, the objects to be cut can be aligned.

Furthermore, when chamfering the object, place the object to be cut along the chamfering contact surface and the chamfering auxiliary surface of the side wall, and push the corner of the object to be chamfered on the bottom surface of the groove. If you touch and operate the planer, you can chamfer the object to be cut.

<Embodiment> An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view of a planer according to an embodiment of the present invention, FIG. 2 is a bottom view thereof, FIG. 3 is a front view thereof, and FIG. 4 is a left side view thereof. ing.

The planer has a configuration in which a substantially V-shaped recess 2 is formed obliquely on the upper surface of a wooden plane 1 and a plane blade 3 is arranged there. The plane blade 3 is made to project from a through hole 10 formed in the recess 2 into a groove on the bottom surface of the plane to be described later.

The plane blade 3 is held by a press metal 5, a receiving metal 6 and an adjusting screw 7 attached to the recessed portion 2 by screws 4a and 4b which are two fulcrums, and the blade 3 is rotated by the adjusting screw 7.
The degree of protrusion from the through hole 10 can be adjusted (see FIG. 3 etc.).

Explaining this point in more detail, the screws 4a and 4b are inserted into the through holes formed in the press metal 5 and the receiving metal 6, and are screwed and fixed to the plane base 1.

Further, a screw hole for screwing the adjusting screw 7 is formed on the opposite side of the presser plate 5 for pressing the plane blade 3, and the adjusting screw 7 is screwed into the screw hole formed on the presser plate 5 for adjustment. The tip of the shaft portion of the screw 7 abuts on the receiving metal 6.

In the above configuration, when the head of the adjusting screw 7 is gripped and rotated, the screw 7 turns around on the receiving metal 6, and the screwed presser metal 5 moves up and down on the screw shaft.

By the vertical movement of the presser 5 on the screw shaft of the adjusting screw 7,
The front part of the presser foot 5 holding the plane blade 3 is screw 4
Using the fixed parts of a and 4b as a fulcrum, the pressing force on the plane blade 3 is strengthened or weakened.

The groove 8 is formed through the bottom surface of the plane 1, and as shown in FIG. 4, it is formed by cutting side walls 1a and 1b having appropriate thickness on both sides in the longitudinal direction of the plane 1.

The inner side surface of the one side wall 1a, that is, the side surface forming the groove 8 is vertically raised from the bottom surface 1c of the groove 8 and the side contacting surface 12 of the object F to be cut is formed. There is.

The inner side surface of the other side wall 1b forming the groove 8 is formed so as to rise at an obtuse angle from the bottom surface 1c of the groove 8 so that the groove gradually expands toward the opening side. The chamfering contact surface 13 is formed.

Further, as shown in FIG. 4, the side wall 1a is notched at the front end opening, and one side of the side wall 1b is brought into contact with the chamfering contact surface 13 for receiving the other side of the object F to be cut. A chamfering auxiliary surface 14 is formed.

In addition, on both outer side surfaces of the plane stand 1, there are concave strips having an arcuate cross section in the longitudinal direction.
11a and 11b are formed so that the fingertips are caught when the canner is gripped to facilitate gripping and the hand does not slip during operation.

An example of use of the above planner will be described.

First, when the object F is aligned, the bottom surface 1c of the groove 8 is pressed against the side surface of the object F and the contact surface 12 for alignment is aligned with, for example, the upper surface of the object F to operate the planer. . As a result, it is possible to correct near the cutting object F.

Next, when chamfering the object F, the chamfering contact surface 13 is made to lie along, for example, the side surface of the object F, and the chamfering auxiliary surface 14 is made to lay along, for example, the upper surface of the object F. By pressing and operating the planer, chamfering of a corner portion of the object F to be cut can be performed.

In addition, the bottom surface of the groove 8 against which the corner of the cutting object F is pressed
If a concave strip 9 having a triangular cross-section as shown in FIG. 4 is formed in the 1c portion, the corner of the object F is chamfered during chamfering, so that only the portion fitted into the concave strip 9 is cut off. Both chamfers that can be performed can be made constant, and chamfering can be performed quickly and in the same amount. Note that, as shown in FIG. 5, it can be carried out even on a flat surface having no recessed line.

In addition, various design changes can be made without changing the gist of the present invention, such as that the plane can be integrally formed of plastic or the like in addition to the above wood.

<Effect of the Invention> According to the planer of the present invention having the above-described configuration, unlike the conventional V-shaped groove and U-shaped groove formed side by side, the abutting groove for the object to be cut is not changed. In addition, various through-holes formed on the bottom surface of the plane can be used for side-by-side alignment and chamfering of objects to be cut.
