Abstract

(57) [Summary] [Purpose] In piping work, a cutting grindstone attached to a disk grinder was used to cut a pipe, etc., but the cutting grindstone was attached to another cutting grindstone shaft and attached to a drill etc. In particular, it facilitates cutting of the pipe in the vertical direction. [Structure] A cutting grindstone shaft having one of the cutting grindstone shafts as a cutting grindstone mounting screw portion and the other as an electric tool mounting part.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an attachment shaft of a cutting wheel used for cutting a pipe in a plumbing work, and is characterized by being attached to a drill or the like and mainly used for cutting a pipe in a vertical direction.

[0002]

[Prior art]

 The cutting whetstone was used by attaching it to an electric tool such as a disc grinder or a sander, but depending on the working situation, it was often inconvenient to use the electric tool.

[0003]

[Problems to be solved by the device]

 The present invention attaches a cutting wheel to another shaft and attaches it to a drill or the like to cut a pipe or the like in the vertical direction as seen by an operator.

In order to cut the pipe that goes toward the worker when the existing underground pipe is relocated, the surrounding area was largely excavated and cut using a guide saw or a disc grinder.

However, the hand-operated saw cuts the saw blade edge in the lateral direction when it is used, so the work is not easy, and the cut surface becomes slanted so that the joints are not joined well and water leakage is caused.

[0006] Further, when cutting with a disc grinder, it is often impossible to cut at right angles and joints of joints often do not work well.

The present invention is intended to solve the above-mentioned problems. That is, the work efficiency is improved by the minimum excavation of the circumference of a pipe or the like, and the shaft for a cutting wheel is a cast iron pipe or a vinyl chloride pipe depending on the use. The cutting stone on the market can be replaced according to the object to be cut.

[0008]

[Means for Solving the Problems]

 The cutting grindstone shaft 1 is composed of a tightening screw part 6 and a cutting grindstone tightening nut 2. The other end of the cutting grindstone shaft 1 is a drill chuck tightening part 3 and other similar mounting parts, which are hexagonal shafts for bits ( There is a shaft with an internal screw attachment (not shown) for the disk grinder (not shown).

The cutting screw shaft 1 may be used by inserting the tightening screw portion 6 of the shaft 1 into the mounting hole of the commercially available cutting wheel 5 and tightening the tightening nut 2.

A drill may be used for a chuck, an impact driver may be used for a bit, a disc grinder may be used for an internal screw, and a power tool may be used.

[0011]

[Action]

 The usage of the cutting wheel shaft is as follows.

The cutting edge 5 ′ of the cutting grindstone shaft 1 attached to an electric drill or the like is rotated to come into contact with a cutting location 9 ′ such as a pipe and to make a round of the circumference, whereby cutting is easily performed.

When the inner diameter of the pipe is larger than the cutting grindstone 5, it is also possible to cut by contacting the cutting edge from the inside of the pipe to the outside.

[0014]

【Example】

 Next, an embodiment of the cutting wheel shaft according to the present invention will be described. When the existing underground pipes are relocated during the plumbing work, to cut the pipe facing the worker, the surrounding area is excavated and the cutting point 9'is exposed to cut, but the object to be cut 9 Since there are various types such as cast iron pipes and vinyl chloride pipes, a commercially available cutting grindstone may be selected and attached to the shaft for use.

The cutting grindstone shaft 1 attached to a trill or the like may be rotated to cut from the periphery of the object 9 to be cut, or when the pipe inner diameter is larger than the cutting grindstone, cutting is performed from the inside of the pipe to the outside. Good.

By using a drill or the like along the object 9 to be cut such as a pipe, the cut surface becomes a right angle, and the joints are joined well.

[0017]

[Effect of device]

 It is possible to easily cut the periphery of the object 9 such as a pipe with minimum excavation, which shortens the working time and also makes it possible to connect joints well because the cutting surface becomes a right angle, and it is effective in eliminating water leakage. .
