体部11に螺入されるねじである。In FIGS. 1 to 5, reference numeral 11 denotes a main body integrally formed with the shaft 12, a fixed blade 13 is attached to the lower end of the main body 11, and a movable portion is provided at one side of the main body 11. A blade 14 is attached. The fixed blade 13 is fitted into a groove 15 formed from the lower end of the main body 11, and is fixed to the main body 11 by tightening with a screw 16 from the front side of the main body 11. Further, at the lower end of the fixed blade 13, a blade portion 17 concentric with the shaft 12 and protruding downward in a state of being fixed to the main body portion 11,
A horizontal blade portion 18 that is located above the blade portion 17 and extends from the blade portion 17 toward the other side portion of the main body portion 11 is provided. These blades 17 and 18 are also formed on the upper end of the fixed blade 13, and when the lower blades 17 and 18 are worn, the screw 16 is removed and the fixed blade 13 is turned upside down for reuse. You can do it. Next, the movable blade 14 is placed in a groove 19 formed in one side portion of the main body portion 11 and is positioned above the blade portion 20 which is long in the vertical direction and which projects downward at the lower end. The main body part (11) is provided with a horizontal blade part (21) extending toward the other side part, and is pivotally supported by the main body part (11) by a pivot shaft (22) in the vicinity of the upper end.
The blade portion 20 moves in and out of the blade 19 and the blade portion 17 of the fixed blade 13
It is easy to see and go. The movable blade 14 has a blade portion 17 of the fixed blade 13 and a blade portion 20 of the movable blade 14 which are screwed from the other side of the main body 11 by means of two upper and lower horizontal screw shafts 23 and 24 with hexagonal holes. The distance between can be finely adjusted. More specifically, the upper screw shaft 23 is located above the pivot shaft 22, and the lower screw shaft 24 is located below the pivot shaft 22, where the upper screw shaft 23 is rotated. And retreat away from the movable blade 14, and then the movable blade 14 is rotated around the pivot shaft 22 to move the blade portion with respect to the blade portion 17.
Adjust the position of 20, and then rotate the two screw shafts 23, 24 to bring the tips into contact with the movable blade 14
14 movements can be stopped. In this way, the movable blade 14 can be finely adjusted, and the movement of the movable blade 14 can be stopped by bringing the tips of the two screw shafts 23, 24 into contact with the movable blade 14. The side face is pushed by the lock screw 25 with a hexagonal hole that is screwed into the main body 11 so that the movement of the movable blade 14 can be stopped more reliably. Reference numeral 26 is a screw that is screwed into the body 11 to prevent the body 11 from opening at the lower end.

を同時加工することができる。When drilling a plate-shaped wooden product or resin product with the counterbore having the above-mentioned configuration, the blade portion 20 of the movable blade 14 and the fixed blade
By adjusting the distance between the blade portion 17 and the blade portion 17 and rotating the main body portion 11 via the shaft 12, the plate-shaped product can be drilled. At that time, the blade portion 17 is located at the center of the hole, and the blade portion 20 is located at the outer periphery of the hole,
The counterbore cone is rotated so that the blade portions 17, 20, 18, and 21 come into contact with the product in this order to carry out the counterbore processing. In the process, while cutting the center of the hole with the blade portion 17, the outer periphery of the hole is scraped with the blade portion 20, but the debris left in the hole is scraped off with the blade portions 18 and 21, and the main body portion. The scraps formed on 11 will rise along the taper surfaces 27, 28 for scraping and will be removed.As a result, even if a plurality of plate-shaped products are punched in a stacked state, It is possible to move from product to lower product in succession, and to process multiple products at the same time.
