The base is movably coupled with the carriage. When sharpening, the carriage and sharpening block bear on the same surface. EFFECT: improved quality of sharpening. 2 dwg

Description

 The invention relates to a device for sharpening the cutting edges of the blades of a carpentry tool.

 A device for sharpening a planer blade is known, which is adopted as a prototype, which comprises a carriage and a pad fixedly connected to it with a clamp for fixing the sharpened blade.

 The sharpened planer blade is clamped to the platform and the entire device is moved along the sharpening bar to sharpen the blade. At the same time, not only the sharpened blade is supported on the bar, but also the carriage of the device.

 The proposed device differs from the known one in that it provides the possibility of sharpening not only straight but also curly cutting edges of the blades of a carpentry tool, with high quality sharpening.

 This effect is achieved by the fact that the shelf with a clip for fixing the sharpened blade is fixed on the base, which, in turn, is connected movably, by means of the longitudinal axis, with the carriage resting on the same surface as the sharpening bar during grinding.

 In FIG. 1 shows a device, side view; in FIG. 2 top view of the device.

 The device comprises a shelf 1 and a cover 2, between which the sharpening blade 4 is fixed using the clamping nuts 3. The shelf 1 is mounted on the base 5, which, through the longitudinal axis 6 and the clamping nut of the carriage 7, is connected to the carriage 8. When the clamping nut of the carriage 7 is released, the shelf 1 with the base 5 can be rotated on the longitudinal axis 6 at any angle. The carriage 8 is supported on the same surface 9 on which the grinding block 10 is also located.

 As the surface 9 for sharpening can be used: a sheet of plywood, disk, table plane, etc.

 Setting the angle of sharpening of the blade 4 is a greater or lesser extension of the sharpened blade 4 relative to the shelf 1.

 The device is used as follows.

 The sharpened blade 4 is mounted on the shelf 1 and secured through the cover 2 with the clamping nuts 3. When sharpening the straight cutting edges of the blades, the carriage 8 is firmly pressed by the clamping nut of the carriage 7 to the base 5. When sharpening the rounded cutting edges, the clamping nut of the carriage 7 is loosened to provide opportunities for sharpening rotational movements of the base 5 with the shelf 1 and the sharpened blade 4 around the longitudinal axis of rotation 6.

 After installation of the blade 4 on the shelf 1, its sharpened surface is placed on the block 10, and the carriage 8 is next to the block, on the surface 9 and, pressing the blade 4 against the block 10, the cutting edge of the blade 4 is sharpened by reciprocating movements along the bar 10.

The proposed device allows you to:
to sharpen the cutting edges of the blades of not only manual carpentry tools (planers, chisels, sherhebel, jointer, etc.), but also electric planers,
Sharpen not only straight but also curly cutting edges of the blades.

for sharpening use bars of almost any size
ensure an unlimited long life, since the device parts work out of contact with the abrasive block.
