Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plane-blade jig used for a plane-blade grinder that grinds a blade for an automatic plane.

[0002]

[Prior art]

In a general plane blade grinder, for example, as shown in FIGS. 5 to 7, a supporting shaft a is provided laterally in the left and right direction of a machine body (not shown), and a tool rest b is pivotally adjusted on the supporting shaft a. Mounted so that it can be fixed, place the plane blade W on the inclined mounting surface c of the tool post b, and apply a plurality of pressing pieces d arranged in parallel to the plane blade W to fix the plane blade W with the mounting bolt e and the mounting nut f. Then, as shown in FIG. 6, the reclining surface W ₁ of the plane blade W is ground by the revolving grindstone M arranged so as to be able to reciprocate in the left-right direction of the machine body, and then the bowl-shaped grindstone N arranged on the side of the revolving grindstone M. Therefore, as shown in FIG. 7, the tip surface W ₂ of the plane blade W is ground.

[0003]

[Problems to be solved by the device]

However, in the case of these conventional structures, in order to grind the back pressing surface W ₃ of the plane blade W which influences the sharpness of the blade, the plane blade W is turned upside down and the plane blade b is attached to the inclined mounting surface c. The bowl-shaped grindstone N and the back-side pushing surface W ₃ are appropriate even if the back-side pushing surface W ₃ is rotated by a bowl-shaped grindstone that grinds the tip end surface with the inclined mounting surface c being substantially horizontal. Since the structure does not match the position and the position of the bowl-shaped grindstone N cannot be moved back and forth, the back pressing surface W ₃ of the plane blade W cannot be ground in the end, and another plane blade grinder is used. Inevitably, it has the disadvantage that the workability of cutting the blade is reduced accordingly.

[0004]

[Means for Solving the Problems]

 The purpose of the present invention is to eliminate these disadvantages, and the gist of the present invention is to mount it on the tool rest of a plane-blade grinder that grinds the resurfacing surface of the plane blade and the tip finished surface. A bowl type that enables grinding of the back pressing surface of a plane blade, and the back surface of the jig is attached to the inclined mounting surface of the tool post with the back pressing surface facing up and the tip finished surface is ground. It is a jig for grinding a plane blade, which is provided with a blade mounting surface on which the plane blade can be mounted so that the backing surface can be ground by a grindstone.

In addition, the jig body is provided with a positioning mechanism for assembling a front blade that is the plane blade that is ground and a back blade that is fixedly attached to the front blade in a superposed state. It is in a jig for grinding.

[0006]

[Action]

 When grinding the back pushing surface of the plane blade, attach the jig body to the inclined mounting surface of the tool rest of the plane blade grinding machine, and place the plane blade on the tool mounting surface of this jig body with the back pushing surface above. It will be installed.

Further, in the case of a two-bladed plane blade that is a front blade that is the plane blade and a back blade that is fixedly attached to the front blade in a superposed state, the front blade and the back blade are attached by a positioning mechanism provided in the jig body. It will be assembled with the blade.

【Example】

1 to 4 show an embodiment of the present invention, in which the same mode parts as those of the structures of FIGS. 5 to 7 are described with the same reference numerals, 1 is a jig main body, which is made of synthetic resin in this case. Made by the bowl-shaped grindstone N for making the mounting surface 2 and the back pressing surface W ₃ placed on the inclined mounting surface c of the tool rest b upward and grinding the tip finished surface W ₂ A substantially horizontal blade mounting surface 3 on which the plane blade can be attached is formed so that W ₃ can be ground, and a pressing piece 4, a mounting bolt 5 and a mounting nut 6 for fixing the plane blade on the blade mounting surface 3 are fixed. It is provided on the tool body 1.

Reference numeral 7 denotes a positioning mechanism. In this case, a contact portion 8 is formed upright on the jig main body 1, and the contact portion 8 has a front edge edge T ₁ of the front blade, which is the plane blade W, and a back blade. A positioning piece 9 having a thickness equal to the distance L from the tip edge T _{2 of} P is attached by a bolt 10 so as to be vertically adjustable, and the edge of the front edge of the front blade, which is the plane blade W, is brought into contact with the blade mounting surface 3. The tool is placed in a state of being pressed against the contact surface 11 of the portion 8, the tip edge T ₂ of the back blade P is pressed against the positioning piece 9, and in this state, the double-edged tools W and P are assembled. It is a thing.

Since this embodiment has the above-mentioned configuration, the reed surface W ₁ of the plane blade W is ground, and then the tip surface W of the plane blade W is ground by the bowl-shaped grinding stone N arranged on the side of the rotary grinding stone M. ₂ is ground, and when grinding the backing surface W ₃ of the plane blade W, the plane blade W is removed from the inclined mounting surface c, and the jig body 1 is attached to the inclined mounting surface c of the tool rest b of the plane blade grinder. mounting, mounting a planer blade W the back pressing surface W ₃ of the planer blade member W on the tool mounting surface 3 of the jig main body 1 and the upper, can be ground by a bowl-type grindstone N in this state, therefore the same tool grinding The backing surface W ₃ can be ground by the board after grinding the surging surface W _{1 of the} plane blade W and the finished surface W _{2 at} the tip, which improves the work efficiency and improves the economical efficiency. .

Further, since the jig body 1 is provided with the positioning mechanism 7, a two-blade type blade having a front blade which is the above-mentioned blade W and a back blade 9 which is attached and fixed to the front blade in a superposed state. In this case, the front blade W and the back blade 9 can be easily assembled, and the blade can be efficiently changed to the automatic plane.

The present invention is not limited to the above embodiment, but the jig body 1 and the like are appropriately designed and changed.

[0013]

[Effect of device]

 As described above, according to the present invention, the backing surface can be ground subsequent to the grinding of the plane of the plane blade and the finished surface of the tip, which can improve the work efficiency and the economical efficiency. With the positioning mechanism, the front and back blades of the double-blade plane blade can be easily assembled, and the blade can be exchanged with the automatic plane efficiently.

As described above, the intended purpose can be sufficiently achieved.
