Abstract

PURPOSE:To correctly polish the cutter edge without removing the cutter from a stationary base by reciprocatively sliding a slide bed frame provided with a rotary grindstone beneath it on the stationary base in the length direction of the cutter fitted to the stationary base for polishing. CONSTITUTION:To polish the edge (c) of a cutter (a) fitted to a stationary base (b), a rotary adjusting handle 8 is rotated to adjust the position of the polishing surface of a grindstone 12 against the cutter (c). Then, the inner surface of a guide plate 21 brings the grindstone 12 invariably in contact with the edge (c) of the cutter (a) with the side end section of the stationary base (b) serving as a guide face, and under this condition, a motor 13 is driven, a bed frame 1 is manually held and reciprocatively slided two or three times on the stationary base (b) in the length direction of the stationary base (b), and the edge (c) of the cutter (a) is polished over its length. Thereby, the cutter can be directly polished without being removed from the stationary base, the rest time of wood machining is shortened, and the work efficiency can be improved.

Description

Detailed Description of the Invention The present invention provides a method for polishing the edge of a blade attached to a surface plate in a super-finishing fishing machine, a hand-pushed fishing machine, an electric fishing machine, etc. that polishes wood boards, and the method therefor. The present invention relates to a device for implementing the above.

Conventionally, super finishing hook machines have been extremely efficient processing machines when performing various woodworking processes, but when grinding the surfaces of many plate-like objects into smooth surfaces, the cutting tool can be used with just a few dozen pieces. There is a risk that the wood surface will become dull and the product value will decline.

For this reason, when a cutter becomes dull, the current practice is to remove the cutter from the surface plate each time, polish the cutting edge, and then mount it on the surface plate while adjusting its position several times. However, there was a problem in that this work required the same amount of time as wood processing, resulting in a significant drop in efficiency.

The present invention has been made in view of these problems, and allows a sliding frame equipped with a rotating grindstone to be slid back and forth on the surface plate without removing the blade of a super-finishing fishing machine or the like from the surface plate. The present invention provides a method and apparatus for polishing a cutting edge, which is characterized by accurately polishing the cutting edge of a cutter by moving the blade.

An embodiment of the present invention will be described with reference to the drawings. Reference numeral (]) is a rectangular cylindrical sliding frame with an opening (2) at the lower end, and the lower surface thereof is formed into a smooth sliding surface (3). (4) is the underframe (1)

In addition, in the case of a hand-pull machine, the guide plate (a) is fixed on the surface plate (b) so as to be parallel to the cutting edge (C) of the knife (a), as shown in Figure 5.6. , this information board (A) has an underframe (
While sliding the lower end of the negative side of 1), place the whetstone (
B) is used to polish the cutting edge of the knife (a) (the bow).

In this way, the cutting edge polishing method according to the present invention involves sliding a sliding base frame with a rotating whetstone on the lower surface back and forth in the length direction of the cutter attached to the surface plate, and polishing the cutting edge of the cutter with the rotating grindstone. Since it is a polishing tool, it is possible to immediately polish the cutter that has been cut without removing it from the surface plate, reducing downtime in woodworking and improving work efficiency.
In addition, by simply sliding the sliding frame back and forth on the surface plate, the rotating grindstone installed on the sliding frame polishes the cutting edge of the cutter attached to the surface plate, resulting in smooth and accurate polishing in a short time. It is possible.

Further, in the polishing device of the present invention, the lower surface of the sliding frame whose lower end is open is formed into a smooth sliding surface, and the grindstone rotating shaft can be adjusted to rotate and move in the zero axis direction within the sliding frame. support,
The grindstone attached to the lower end of the rotating shaft faces the lower end opening of the sliding frame, and the Tanabata rotating shaft installed on the upper surface of the frame is connected to the grindstone rotating shaft. Since the whetstone can be adjusted by moving down two degrees, it can be easily adjusted to an accurate polishing position relative to the cutting edge of the cutter attached to the surface plate, and the bottom surface of the frame is formed into a smooth sliding surface. So,
The underframe can be manually gripped and slid smoothly on the surface plate, and the tool can be efficiently polished while checking the polishing state of the blade.
