整機構に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a screw seat forming device that forms screw seats for a plurality of hinge fixing screws at once. This invention relates to a mechanism for adjusting the position of a countersinking edge of a drill.
通常、蝶番は２ないし４個のねじでドアに固定される。 Typically, the hinge is secured to the door with two to four screws.

ドリル状のねじ座形成装置については１本出願人の提案
に係るものがある（特願昭６０−１１２５９９号）。When fixing the hinge slats in a hidden state inside the door, screw seats for sinking the screw heads into the door side are formed in correspondence with the number of screws. A multi-axis drill-like screw seat forming device for forming such screw seats all at once has been proposed by the present applicant (Japanese Patent Application No. 112599/1982).

調整用のシムや座金を用いて座ぐり刃２３の位置調整を
行う必要があった。When polishing the drill 7 or replacing some of the drills 7 in a set, variations occur in the axial position of the countersink blade 23,
- The depth of the screw seats in the set may be uneven. This is because the counterbore blade 23 is positioned with the stepped wall 25 in contact with the output shaft 6. To align the depth of the screw seat, an adjustment shim or washer is used to countersink the blade 23. It was necessary to adjust the position of the

と干渉したり衣服を引っ掛けたりする。If the depth of the screw seat is inappropriate, various problems will occur during use. For example, if the screw seat is too deep when the machined surface does not have sufficient thickness, such as a door made of steel, the screw head will miss the hinge and the hinge will not be able to be fixed. On the other hand, if the screw seat is shallow, the screw head will protrude from the side end face of the door and interfere with the opening frame or catch clothes.

することを目的とする。The present invention provides an apparatus for forming a screw seat for fixing a hinge, in which the position of a countersink blade formed on a drill can be easily adjusted, and the depth of a set of screw seats can be appropriately formed. With the goal.
従来装置の問題点は、ドリル７に作用するスラスト力を
出力軸６で直接的に受は止める構造としていたことにあ
る。The problem with the conventional device is that it has a structure in which the thrust force acting on the drill 7 is directly received by the output shaft 6.

図のように筒状のボルト様にしてもよい。In this invention, from this point of view, the output shaft 6 as shown in FIG.
The adjustment screw mechanism 28 provided at the shaft end of the drill 7 is configured to receive and stop the thrust force, and the stop position of the receiver can be changed and adjusted, thereby making it easy to adjust the position of the countersinking blade 23 of the drill 7. I made it possible. - Specifically, a fixed screw member 29 is formed on the output shaft 6, and the positioning step portion 25 of the drill 7 is received and supported by the thrust receiving surface 32 of the movable screw member 30 that engages with the fixed screw member 29. If necessary, the movable lock member 30 can be prevented from rotating with a lock nut 31. In the embodiment shown in FIG.
It may be shaped like a cylindrical bolt as shown in the figure.

置を適切なものに調整する。If the position of the counterbore blade 23 becomes uneven due to replacement or polishing of the drill 7, the position of the thrust receiving surface 32 is changed by loosening the lock nut 31 and screwing the movable screw member 30 back and forth. In this state, the positioning step portion 25 is brought into contact with the thrust receiving surface 32, and if the positions of the matching counterbore blades 23 match, the movable screw member 30 is locked by the lock nut 31. If further adjustment is necessary, the position of the thrust receiving surface 32 is adjusted to an appropriate position by operating the movable ratchet member 30.

を一掃して。According to the present invention as described above, when a plurality of screw seats 20 are formed on the door D at the same time, the position W of the countersink blade 23 is
Since flill adjustment can be easily performed, the depth of the screw seat 20 of the negative set can always be set to an appropriate depth. This eliminates problems such as the inability to fix the hinge H or the protrusion of the screw head due to variations in the depth of the screw seats 20 of the negative set.
ねじ座２０を能率良く形成できることになる。This means that the screw seat 20 can be formed efficiently.
また、座金や調整シムを用いて座ぐり刃２３の位置調整
を行う場合に比べて、調整作業を短時間で的確に行うこ
とができる点で有利である。Moreover, compared to the case where the position of the countersink blade 23 is adjusted using a washer or an adjustment shim, it is advantageous in that the adjustment work can be performed accurately in a short time.
