JPH0627015U - Sharpening machine for polishing the chainsaw blade of a chain saw - Google Patents

Abstract

(57) [Abstract] [Purpose] The present invention relates to a sharpening machine that grinds blades of a chain of a chain saw so that all angles are uniform. [Structure] The grinder 1 and the fixture 11 are united and fixed to a guide bar 12. Then, the grinder 1 is moved by the left and right movement grinders of FIG. 3, the angle is adjusted by the angle adjusting stopper 10, and the chain of the chain saw is sharpened.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a sharpening machine in which all the blade angles of a chain of a chain saw are uniform.

[0002]

[Prior art]

 To sharpen the blade of a conventional chain saw, a round file or a motorized circular whetstone was used to sharpen the blade, but the proper angle could not be determined. As a result, the angles of the blades of the chains became uneven, and even when cutting wood, the sharpness of the chainsaw was poor, and the chain saw body was burdened, causing the chain saw to malfunction. And while working on the chain saw, it was dangerous as it bounced back.

[0003]

[Problems to be solved by the device]

 This plan eliminates these drawbacks, sharpens the blade of the chain properly, reduces the risk of chain saw failure and risk, and enables safe chain saw work.

[0004]

[Means for Solving the Problems]

 Now, the solution means will be described with reference to the drawings. (A) The center fixed scissors 2 are set at the center with respect to the guide bar 12. (B) Turn the fixing fastener bolt 6 to firmly fix it to the guide bar 12. (C) The grinder left-right movement fastener 9 of FIG. 3 is moved right or left to the angle adjustment stopper 10 and fixed.

[0005]

[Action]

 Since this plan has the structure as described above, when using it, (a) switch on the grinder 1, hold it by hand, and bring it closer to the blade of the chain. At that time, the first bend 4 and the second bend 5 Turns. (B) For the first bending, allow the grinder 1 to move about 5 mm back and forth, and apply the diamond grindstone 3 to the blade of the chain to polish. (C) Since the chain blades are on both the left and right sides, if the blade of one chain can be polished, move the chain 7 and polish the blade of one chain. (D) To grind the blade of the other chain, move the grinder left and right fasteners 9 to the angle adjustment stoppers 10 on the opposite side and fix them.

[0006]

【Example】

 In implementing the present invention, the following can be done. (A) Wearing a magnifying glass 8 makes it possible for even people with poor eyesight to stand up, and even if it is dusty, it can cover the eyes. (B) Since the chain blade has various sizes, the diamond grindstone 3 also has various thicknesses and can be replaced with the grinder 1.

[0007]

[Effect of device]

 Therefore, the angles of the chain blades are all the same, and the load on the chain saw body is not applied, and safe chain saw work can be performed.
