A helical threaded portion 3b, a columnar straight portion 3c, and a rectangular sandwiching portion 3d are formed at the upper end. Then, the holding portion 3d is held by a chuck portion 4a provided at the center of the tap handle 4, and the handgrips 4b at both ends of the tap handle 4 are gripped and turned, whereby the tap 3 is turned to be covered. A female screw is formed in a prepared hole 5a formed in the surface of the cut object 5.

ることにより雌ネジ加工が刻設されて行く。The holding portion 3d of the tap 3 is loosely attached to one end of a handshake 4b by a chuck portion 4a of a tap handle 4, and is configured to move directly in the horizontal direction by rotating the handshake 4b (see FIG. 1). (Not shown). Normally, a pilot hole 5a having a diameter smaller than the desired female screw diameter is drilled in advance on the surface of the workpiece 5 by drilling, and then the screw introduction portion 3a of the tap 3 is inserted into the pilot hole 5a. 3 is visually corrected so that the axis of 3 is perpendicular to the surface of the workpiece 5,
By turning the tap handle 4 and the tap 3 and inserting the threaded portion 3b sequentially from the screw introduction portion 3a, the female screw processing is engraved.

物５自身が不良品となる虞れがある。By the way, at the time when the female screw is formed at the screw introducing portion 3a, the posture of the tap 3 is very unstable, the tap 3 easily fluctuates, and the axial center of the tap 3 is
Applying a female screw by hand while making it coincide with the axis of "a" requires considerable skill and is a very difficult task. And
If the tapping 3 is continued and the internal thread processing is performed while the axis of the tap 3 does not coincide with the axis of the pilot hole 5a, the screw hole is inclined or the tap 3 is broken in the pilot hole 5a, and the broken tap 3 is covered. It may take a lot of time to remove the material from the cutting 5, or the cutting 5 itself may be defective.

ガイド１を容易に取り外すことができる。As shown in FIG. 1, a tap guide 1 according to the present invention is made of a columnar metal, and has a guide hole 1a vertically penetrating with an inner diameter in which a tap 3 can be inserted. I have. A locking step 1b is formed in the guide hole 1a, and the tap 3 inserted and held in the guide hole 1a is formed.
The spring 2 for urging in the direction in which the oil is discharged can be locked. The spring 2 can prevent interference between the tap 3 and the guide hole 1a, and
After the screw introducing portion 3a of the tap 3 is inserted into the prepared hole 5a of the work 5 and the tap 3 is vertically positioned and stands, the tap guide 1 can be easily removed.

動させて雌ネジ加工を行なうのである。First, the tap 3 is loaded together with the spring 2 into the guide hole 1a of the tap guide 1. Next, the lower surface of the tap guide 1 is brought into contact with the surface of the iron plate 5, and the screw introduction portion 3 a of the tap 3 is inserted and placed in a prepared hole 5 a formed in the surface of the iron plate 5. Thereby, the axis of the pilot hole 5a and the axis of the tap 3 can be automatically matched. Next, a tap 3 protruding from the upper end of the guide hole 1a
Is slightly rotated using a wrench or the like.
As a result, the tap 3 is erected and fixed in a vertically positioned state, so that the tap guide 1 and the spring 2 are removed from the tap 3. Finally, the clamp 3d of the tap 3
The portion is pinched and rotated by the chuck portion 4a of the tap handle 4 to perform the female screw processing.

ａの軸心と自動的に一致することとなる。After aligning the axis of the pilot hole 5a with the axis of the tap 3, the screw introducing portion 3a is inserted into the pilot hole 1a while the tap 3 is held in the guide hole 2a. If the tap 3 is slightly rotated, the tap 3 is fixed upright by the guide hole 2a, and the axis of the tap 3 is
It will automatically coincide with the axis of a.

ができる。Therefore, even if the tap guide 1 is subsequently removed, the tap 3 can be rotated in a stable state without swaying, and the axis of the tap 3 and the axis of the pilot hole 5a are aligned. Female screw processing can be easily performed. Therefore, it is possible to prevent an accident such that the female screw hole to be processed is inclined or the tap 3 is broken in the prepared hole 5a.
