本考案は、特にガラスパイプの内径面を研磨又
は研削する砥石に関する。[Detailed Description of the Invention] The present invention particularly relates to a grindstone for polishing or grinding the inner diameter surface of a glass pipe.

り、パイプの内径を所要の寸法に仕上るという方
法が採られていたものである。 Conventionally, a method commonly called sanding has been used to polish or grind the inner diameter surface of a glass pipe. This is done by mixing commonly known single abrasive grains such as alumina oxide (WA), silicon carbide (GC), and carborundum (C) with water, and inserting a steel rod into the inner surface of the glass pipe to be ground. The method used was to fill the above-mentioned single abrasive grain between the inner surface of the pipe and a steel rod and rotate the steel rod to finish the inner diameter of the pipe to the required dimension.
然しながら、上記のように従来方法では、この
種ガラスパイプ内径面の研削手段としては能率が
悪るく、またその精度においても欠ける所があつ
た。 However, as described above, the conventional method has poor efficiency as a means for grinding the inner diameter surface of this type of glass pipe, and also lacks accuracy.
そこで本案の目的としては、研削能率を増大
し、同時にガラスパイプ内径研削の精度を向上せ
しめることにある。 Therefore, the purpose of the present invention is to increase the grinding efficiency and at the same time improve the accuracy of grinding the inner diameter of the glass pipe.

第１図ｂに示すように、分離して取付けると研削
物との摩擦性を適度に調整できるものである。 To explain the configuration of the present invention with reference to the drawings, the center assembly part of the elastic plate 2 whose end face is 〓 is clamped with a quarter part provided at the tip of the steel shaft 1, and the end is firmly secured with a nut 3. It is a rotary grindstone which is fastened and has grinding pieces 4 mixed with diamond abrasive grains attached along the longitudinal edge 6 of each elastic plate 2, and the above-mentioned steel shaft 1 is the main axis of rotation. In addition, if necessary, an elastic plate 2 can be separately attached to the tip of the shaft as shown in FIG. 1b, so that the friction with the object to be ground can be adjusted appropriately.

に向け端縁６を湾曲して設置する。 As described above, the structure of the proposed grinding wheel is used for grinding the inner diameter of a glass pipe, and the grinding piece 4 is made of metal bond mixed with diamond abrasive grains, resin bond, or other electroplated bond. The outer diameter D of the piece 4 is the glass pipe 5 to be ground.
The outer diameter of the elastic plate 2 that supports the grinding piece 4 is reduced and inserted into the pipe 5,
The grinding piece 4 is installed so as to rotate in a fixed direction while constantly pressing against the inner diameter of the pipe 5 by the elastic plate 2. However, when the elastic plate 2 is rotated, pressure F is applied to the inner diameter surface of the glass pipe 5, and in order to ensure smooth rotation, the elastic plate 2 is installed with its end edge 6 facing backward in the rotation direction.
本案の砥石はガラスパイプ５の内径面におい

は勿論、研削精度を向上し、構造が簡単で従来の
研削装置にその侭使用可能なる等の実用的効果を
有するものである。 The proposed grindstone rotates on the inner diameter surface of the glass pipe 5 while pressing each grinding piece 4 from inside, so it not only has superior grinding efficiency compared to the sanding method, but also improves grinding accuracy and improves the structure. It is simple and has practical effects such as being able to be used in addition to conventional grinding equipment.
