[0011]

[Function] About the case where the scooping surface and the second side of the tip saw attached to the periphery of the base metal in a set shape are polished to improve the sharpness, and at the same time, the overall shape of the base metal is finished in a balanced shape explain. The lever is set at the point A shown in FIG. Then, the axis of the rotation support shaft is larger than the horizontal line passing through the axis of the mounting shaft.
It is located on the near side, that is, on the rear side .

In this state, the base was fitted without being tightened to the mounting shaft, and then the movable base was advanced so that the grindstone was positioned on one of the saw teeth provided on the base. After that, at the same time as adjusting the rotation of the base metal so that the scooping surface of the chip hits the cutting surface of the whetstone uniformly, the grinder mounting base is also horizontally rotated about the rotation axis, and then the base metal and the grinder mounting base are adjusted. Fix it.

In this case, even if the base metal has a different sawtooth shape, it is possible to easily set the cutting surface of the grindstone and the scooping surface of the chip so as to coincide with each other by the adjustment operation described above. If the diameter of the gold is large, move the moving table backward with respect to the grinder mounting table, and if the diameter is small, move the moving table forward to set the base metal and the grindstone at the correct position. .

Next, the grinder mounted on one side of the grinder mount is rotated about a support shaft in a vertical plane, and the grindstone is angled so as to have a predetermined inclination angle (for example, 15 degrees). Adjust.

Next, the movable mount provided with the stopper device is moved forward, and the engaging pin is properly and elastically engaged with the tooth bottom of the sawtooth by operation of the elastic machine.

After the above adjustment operation is completed, the lever is
Is advanced rotated toward the more A'position position, the base metal also by moving device is moved in a counterclockwise direction as an axis of rotation support shaft not rotating state toward the counterclockwise direction by sawtooth two frames As it is, it moves backward in an arc with respect to the grindstone and is locked by the locking pin.

Therefore, while rotating the grinding wheel at high speed,
If the lever is turned backward from A 'position to A position,
Axis B of the mounting shaft by operation of the moving device as shown in FIG. 7
′ Shifts to the B position, and accordingly, the base metal also moves from the C ′ position to the C position.
They are arc-shaped forward move towards the grinding wheel on the basis of the non-rotating state towards the position.

[0018] By the way, when the time, such as moving the above-mentioned,
Axis D of the pivot support shaft is rotated the base point of the transfer Do杆is because they are located on the rear side than the left-right direction of the line Y'through the axis B of the mounting shaft, the arcuate toward the base metal to the grinding wheel when the advanced moving the saw teeth of the incoming angular E'increases against the cutting surface is prevented from only tooth is cut hits the cutting surface, the entire rake face is cut upon average.

In the above operation, when the scooping surface of one chip is cut at a predetermined inclination angle, the lever A position and the lever A position
'If caused to repeated reverse rotation operation before half the number of sawtooth number between position, the base metal after being擺動sawtooth two frames counterclockwise, the arcuate forward moved toward the grindstone, one The scooping surface of every other chip is accurately cut, and the cutting work of one of the clams is completed.

When the cutting operation of the scooping surface of one of the chips is completed as described above, while the lever is set at the position A, the base metal is rotated and shifted by one saw tooth frame to tighten it. after the grinder support shaft as the axis
In the same rotation range as the previous rotation range,
After turning the grindstone in the opposite direction to the front and adjusting the angle by the same inclination angle, if the lever is rotated back and forth by half the number of saw teeth between the position A and the position A ', the other tip of the sorting set Is scooped every other frame at a predetermined inclination angle in the same manner as described above.

By the way, when the grinder device is inverted,
When trying to cut the other uncut scooping surface, FIG.
A vertical line X passing through the axis of the support shaft as shown in FIG.
(This line is the center of the grindstone surface when the grindstone surface is vertical.
Is set to pass through)
Since the intersection with the horizontal line Y passing through the center of the grindstone when in the state is the tilting center point Z of the grindstone, the grinder device is rotated in a horizontal plane to invert the grindstone vertically and symmetrically. Also adjust the tilt angle exactly the same on the left and right,
The scooping surface of the tip saw provided in a distributed set can be cut at the same left and right inclination angles.

As shown in FIG. 6, the grindstone is positioned forward of the turning shaft so that a vertical line X 'passing through the axis of the turning shaft passes through the center of the grinding surface of the grindstone. so it is,
At the time of the grinding operation, the scooping surface of the chip is concentrated on the center of the cutting surface and the cutting is performed, so that the grindstone can be used for a long time without being deformed and worn.

Next, the case of cutting the second face of the tip saw will be described.

The lever is set at the position A, and then the grindstone is positioned at the dashed line position in FIG. 7 so that the second face of the one chip can be cut into a predetermined shape at an appropriate inclination angle. As described above, the grinder mount is horizontally rotated about the rotation axis, and the grinder device is rotated upward about the support axis to set the grindstone at a desired inclination angle.

Next, after mounting the base metal on the mounting shaft, the movable base is advanced toward the grinder mounting base, and the second surface of the tip is brought into contact with the cutting surface of the grindstone.
The movable mount is moved forward, and the locking pin of the stopper device is elastically locked to the root of the saw tooth.

Next, the grindstone is rotated at a high speed,
If the forward and backward rotation operation is performed half the number of saw teeth between the lever A position and the A ′ position, the base metal does not rotate counterclockwise by two saw teeth as in the case of cutting the scooping surface. or is arcuate backward moved to the grindstone remains, also, is contacted with arc-shaped forward move has been grindstone toward the left grinding wheel not rotating state, Ken sequentially grinding is one of double-dip surface long press of tipped by Kezumen Is done.

When the second face of the chip is cut off by the above operation, the base metal is rotated so as to be shifted by one saw tooth frame, and the grinder is turned downward about the support shaft so that the grindstone is the same. After adjusting the angle in the counterclockwise direction by the tilt angle, if the rotation between the lever A position and the A 'position is moved forward and backward by half the number of saw teeth in the same manner as described above, the other uncut tip is rotated. No. 2 face of the tip saw is cut exactly with the opposite inclination angle from the front, and the No. 2 face of the tip saw that shows a set
At the same time as sharpening and sharpening the tip saw,
The outer shape of the base metal can be finished in a well-balanced shape.

Although the above description has been made with respect to the polishing of the tip saw attached to the saw blade of the sorting clam, the present invention can be applied to a base metal without a tip saw or a circular saw without a sorting saw. Either 8 blades to 120 blades can be obtained by changing the distance between the mounting shaft and the rotation support shaft, as long as the scooping surface of the saw blade and the second surface can be easily cut using a grinder. Correction polishing of the tooth back of the base metal can also be easily performed.
