Description

【考案の詳細な説明】 〔産業上の利用分野〕 この考案はガラス切断具に関するものである。[Detailed explanation of the idea] [Industrial application field] This invention relates to a glass cutting tool.

A head is connected to the tip of the cylindrical holder, and a circular cutter is rotatably attached to the tip of the head.
Glass cutting tools have conventionally existed in which cutting work is performed by guiding oil filled inside the holder to the outer cutting edge of the cutter.

By the way, conventional glass cutting tools have a structure in which oil is guided to the outer periphery of the cutter by opening an air exchange passage provided at the rear end of the holder, and the flow of oil is blocked by closing the passage. The oil passage had to be made narrow, and if it became too narrow, the oil could no longer flow through it, making it very time-consuming to form the passage. Furthermore, since oil is supplied by capillary action, the amount of oil supplied cannot be controlled, resulting in the problem of excess or deficiency of oil.

Therefore, the technical problem of this invention is to eliminate the above-mentioned disadvantages and to make it possible to adjust the amount of oil supplied to the cutter.

In order to solve the above problems, this invention connects the plug of the air exchange passage to the rear end of a cylindrical holder so as to be movable in the axial direction, and attaches a head to the tip of the holder. A cutter is rotatably attached to the tip of the head, and the head has a passage that communicates with the inside of the holder and has an opening at the tip facing the upper outer circumference of the cutter, and makes contact with a valve seat provided in the middle of the passage. A separable valve element is provided, and the valve element and the stopper are interlocked so that they move together in the holder axis direction.

In the cutting tool configured as described above, when the stopper is moved in the axial direction while the inside of the holder is filled with oil, the air exchange passage opens and the valve separates from the valve seat. Therefore, the passage becomes open, and the oil inside the holder flows through the passage and flows out from the opening at the tip, allowing oil to be supplied to the outer periphery of the cutter.

Further, a connecting tube 11 provided on the head 10 is screwed to the tip of the holder 1. In the case of the embodiment, the head 10 and the connecting tube 11 are separate members, but the connecting tube 11 may be provided integrally with the head 10. The head 10 is formed into a flat rectangular shape, and although not shown in the drawings, the flat surface of the outer periphery serves as a guide surface for a ruler.

Further, the head 10 is formed with a passage 14 for oil flow communicating with the inside of the holder 1, and the opening at the tip of the passage 14 faces the upper outer circumference of the cutter 13. In addition, a valve seat 15 is provided in the middle of the passage 14.
is formed, and a valve body 16 is formed above the valve seat 15,
A spring 17 is arranged to press the valve body 16 against the valve seat 15. The valve body 16 includes a valve stem 18 , and the upper part of the valve stem 18 is inserted into an insertion hole 19 formed in the axis of the stopper 2 , and the lower surface of the head 20 provided above is inserted into the upper part of the valve stem 18 . When the stopper body 2 is rotated in the loosening direction, the valve body 16 moves in a direction away from the valve seat 15.

Now, when the plug body 2 is rotated in the loosening direction, the air exchange passage 5 is opened, and the valve stem 18 is pulled up by the engagement between the top surface of the plug body 2 and the head 20.
The valve seat 16 is separated from the valve seat 15. Therefore, the oil inside the holder 1 flows from the passage 14 into the gap formed between the valve body 16 and the valve seat 15, and is supplied to the outer circumference of the cutter 13 from the opening at the tip of the passage 14.

As described above, in this invention, the plug body for opening and closing the air exchange passage and the valve body that can come into contact with and separate from the valve seat are linked so as to move in the axial direction of the holder. The amount of movement of the valve body can be adjusted by the movement, and the amount of oil supplied to the outer circumference of the cutter can be adjusted. Therefore, the inner diameter of the passage can be made relatively large, and processing is easy. Further, when the plug body is moved in the axial direction to close the air exchange passage, the valve body comes into contact with the valve seat, so that oil leakage can be completely prevented.
