Description

[Detailed Description of the Invention] The present invention relates to a measuring tool for adjusting the cutting edge of a planer in a woodworking planer.

In order to adjust the cutting edge of a wood planer for good cutting, it is necessary to set the exit restraint and the level difference at the cutting edge to several tens of microns over the entire width of the blade, but conventionally this was done by the operator's manual intuition. I relied on them to make adjustments.

However, it is extremely difficult and unstable to make adjustments based on intuition, and requires skill, but it takes a great deal of time and experience to make adjustments accurately and accurately. I couldn't expect a quick adjustment.

The present invention is an adjustment measuring tool devised in view of the above-mentioned problems, and allows even unskilled personnel to easily perform adjustments by expressing numerical values such as the adjustment of the planer's cutting edge and exit restraint without relying on intuition.

An embodiment of the present invention will now be described with reference to the drawings.

In the figure, 1 is a base body, which has a horizontally long slit 2 running through it, and inside this slit 2, a horizontal rod 5 with rollers 3, 3 at both ends and a ball bearing 4 in the center is connected to the shaft. It is attached to the base body 1 by 6.

Reference numeral 7 denotes an inverted dial gauge mounting base, which is attached to one end of the base 1, and a dial gauge mounting hole 8 is vertically bored in the head of this dial gauge mounting base 7. The mounting hole 8 is slotted vertically to the tip of the head of the mounting base to form a bifurcated shape, and a through hole 9 and a screw hole 10 are provided at a position perpendicular to the slot, and a fixing screw 11 is installed therein. The dial gauge 12 is screwed into the dial gauge mounting hole 8 to fix it.

The other end of the base body 1 has an arcuate edge 13 centered around the roller 3 of the horizontal rod 5, and a splint 14 is attached to the back of the dial gauge mount 7 with set screws 15 and 15. Protrusions 16, 16.16 are provided on both ends of the bottom surface of the splint 14 and on the bottom surface of the arcuate edge 13 at the other end of the base body 1, so that the base body 1 is supported at three points.

In addition, 17 is a planar table, 18 is a two-piece type rotary blade, 19 is an exit presser, 20 is a feed roller, and 21 is a positioning stopper.

Since the present invention is constructed as described above, when it is time to adjust the cutting edge of the planer, first insert the positioning stopper 21 from the back of the table 17 to the bottom surface of the exit presser 19, and insert the positioning stopper 21 into this stopper. After applying the arcuate edge 13 of the tool (that is, the product of the present invention) and applying the roller 3 to the exit presser 19 and adjusting the pointer of the dial gauge 12 to the zero point, the roller 13 is moved as shown in Figure 3 of the drawings. Rotary blade 1
The tool is moved back until it reaches just below the cutting edge No. 8, and the level difference between the position of the cutting edge with respect to the table and the position of the outlet stopper is measured, and the cutting operation is performed by adjusting the level difference to a desired level.

As described above, in this invention, the level difference between the exit presser and the cutting edge relative to the table is indicated on the scale of the dial gauge via the roller installed at the rear end of the horizontal lever, so the height difference is indicated on the scale of the dial gauge. The relationship between the cutting edge and the exit retainer can be freely adjusted.

However, since both the measurement of the cutting edge and the measurement of the exit restraint are performed by applying a roller, there is no risk of damaging the cutting edge due to the measurement operation.

In addition, the arcuate edge provided at the tip of the base that touches the positioning stopper is concentric with the center of the roller provided at the tip of the horizontal rod. Since it is possible to quickly adjust the zero point of the exit restraint without having to precisely align it at right angles to the blade, it has a great practical effect as a measuring tool for adjusting the cutting edge of a planer.
