Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a grinding wheel shaping tool used for sharpening, reshaping, etc. of a grinding wheel.

(Prior art) Diamond dressers used for sharpening and refinishing grinding wheels include single-stone diamond dressers and multi-stone diamond dressers.These have diamond grains waxed onto the tip of a short steel handle. It is available as a bonded or sintered machine, and is mainly used by attaching it to a mechanical grinder.The handle is short and dangerous, making it unsuitable for hand-held work.

In addition, single-stone diamond dressers have single-stone diamond grains placed at the tip on the axis of the handle, and multi-stone diamond dressers have multi-stone diamond grains arranged in a plane perpendicular to the axis of the handle. Dressing of the grinding wheel using these single-stone diamond dressers and multi-stone diamond dressers was carried out by feeding the diamond grain portion in an extension direction with respect to the axis of the handle and moving it in a direction perpendicular to it.

In other words, the axis of the handle was perpendicular to the dressing surface.

(Problems to be solved by the invention) Conventional diamond dressers have a flat grindstone with its center attached to the horizontal rotating shaft, a single-dented grindstone with its center attached to the horizontal rotating shaft, and a double-dented grindstone around its circumference. There was a problem in that it was difficult to use it in a hand-held state when shaping surfaces, shaping the downward annular grinding surface of a cup-shaped whetstone whose center portion was attached to a vertical rotating shaft, or a ring-shaped whetstone.

(Means for solving the problem) The present invention can be carried in hand without causing any danger, and can be applied to the circumferential surface of a flat whetstone, one concave whetstone, the circumferential surface of a double concave whetstone, a cup-shaped whetstone with a downward concave shape, and a ring-shaped whetstone. The device can be adapted to the grinding surface such as the annular grinding surface of the whetstone by changing the orientation of the mounting member relative to the handle, and has a multi-stone diamond shaping piece fixed to the upper side of the parallelogram base metal, and A mounting member having a left hypotenuse screw hole or a right hypotenuse screw hole perpendicular to the axis on the left hypotenuse or right hypotenuse is provided, a male thread is formed at the tip, and a handle having a grip is provided, and the male screw The present invention provides a grinding wheel shaping tool in which a mounting member is screwed into a left hypotenuse threaded hole or a right hypotenuse threaded hole, and a mounting member is detachably attached to a handle.

(Function) When sharpening the annular grinding surface of a cup-shaped grindstone or ring-shaped grindstone fixed to a horizontal rotating shaft, screw the male threaded part of the handle into the left hypotenuse threaded hole or right hypotenuse threaded hole of the mounting member. By making the longitudinal direction of the mounting member oblique with respect to the axis and gripping the gripping portion, the annular grinding surface can be sharpened from the side with a multi-stone diamond shaping piece and refinished.

In addition, when sharpening or refinishing the downward-facing annular grinding surface of a cup-shaped grindstone or ring-shaped grindstone mounted downward on a vertical rotating shaft, screw the male threaded part into the left hypotenuse threaded hole or right hypotenuse threaded hole to align the axis of the handle. On the other hand, by making the longitudinal direction of the attachment member oblique, the grip part is gripped, and a multi-stone diamond shaping piece is applied from below to sharpen and reshape.

(Embodiment) To explain an embodiment of the present invention with reference to the drawings, as shown in FIGS. 1 and 2, the grinding wheel shaping tool 1 consists of a mounting member 2 and a handle 3. It can be attached and detached freely.

As shown in FIGS. 3 to 7, the mounting member 2 has a rectangular multi-stone diamond shaping piece 5 in a groove 4b carved in the upper side 4a of the parallelogram-shaped base metal 4 having a thickness a. The lower part of the parallelogram base metal 4 is fixed by brazing, and a left hypotenuse screw hole 6 is bored in the left hypotenuse part 4c of the parallelogram-shaped base metal 4.

The multi-stone diamond shaping piece 5 is made by sintering a plurality of diamond grains together with metal, and in this case, a reference line 7 is shown to indicate the thickness b that can be used for shaping work.

The axis of the left oblique side screw hole 6 is perpendicular to the left oblique side portion 4c.

The handle 3 has a male threaded portion 3a at its tip and a gripping portion 8 at its rear.
A grip part 8 is set at the front position in the axial direction of the handle, or can be moved slightly rearward from the front position and set at the rear position, and a hook ring 9 is provided at the rear end and a finger hook part 10 is provided at the middle part. There is.

When the male threaded portion 3a of the handle 3 is screwed into the left oblique screw hole 6 of the mounting member 2 and the mounting member 2 is connected and fixed to the handle 3, the longitudinal direction of the mounting member 2 becomes oblique to the axis of the handle 3, When the multi-stone diamond shaping piece 5 is on the upper side and the axis of the handle 3 is horizontal, the shaping surface 5a
is slanted to the upper left, and the mounting member 2 and handle 3 are in an inverted C-shape.

In other words, if the shaping surface 5a is on the upper side and horizontal, the handle 3 will be in an upward and upper right diagonal shape, and in this case,
The angle α between the axis of the handle 3 and the shaping surface 5a is set to 15 degrees, and this angle is optimal in terms of shaping resistance and handle retention when gripping the handle 3 and shaping the grinding stone with the shaping surface 5a. The angle α is preferably between 15 degrees and 30 degrees.

Instead of this example, if a right oblique threaded hole is drilled in the right oblique part, the male threaded part 3a of the handle 3 is screwed into the right oblique threaded hole of the mounting member 2, and the mounting member 2 is connected and fixed to the handle 3, the mounting member The longitudinal direction of 2 is oblique to the axis of the handle 3, and the multi-stone diamond shaping piece 5 is on the upper side of the handle 3.
When the axis of the handle is horizontal, the shaping surface 5a has an upward and lower left oblique shape, and the mounting member 2 and the handle 3 have an F-shape.

In other words, if the shaping surface 5a is on the upper side and horizontal, the handle 3 will be diagonal to the lower left, and in this case, the angle between the axis of the handle 3 and the shaping surface 5a is also the same as the angle α, which is the optimum angle ( (See Figure 8).

Since the present invention is constructed as described above, as shown in FIG.
and hold the shaping surface 5a of the multi-stone diamond shaping piece 5.
Lightly press the ring-shaped whetstone against the grinding surface of the ring-shaped whetstone while sliding it from side to side for sharpening, refinishing, etc.

In addition, when sharpening or refinishing the annular grinding surface of a cup-shaped grindstone or ring-shaped grindstone attached to a horizontal rotating shaft, a diamond shaping piece 5 is inserted from the side on the horizontal annular grinding surface of the cup-shaped grindstone or ring-shaped grindstone. It is possible to apply the shaping surface 5a for sharpening or the like.

(Effect of the invention) The present invention has a mounting member made by fixing a multi-stone diamond shaping piece to a parallelogram base metal, by drilling a left hypotenuse screw hole or a right hypotenuse screw hole, and adjusting the orientation of the mounting member with respect to the handle. It is possible to immediately respond to the shaping of the grinding surface of the grinding wheel by changing it to a desired state.
