本発明は、セラミック製の円筒状部材の製作方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method of manufacturing a cylindrical member made of ceramic.
従来、第１図に示すようなセラミック製の釣糸用ガイド
プーリ（Ａ）は、まず、セラミック原料を金型に入れた

を大幅に低下させていた。Conventionally, a ceramic fishing line guide pulley (A) as shown in Fig. 1 has been manufactured by first putting ceramic raw material into a mold, press-molding it to obtain a cylindrical molded product, and firing this. are doing. As a result of this firing, approximately 20% of the molded product
Shrink. However, during melting, the shrinkage of the lower side of a cylindrical molded product is hindered by its own weight, and the amount of shrinkage on the upper side becomes larger than the amount of shrinkage on the lower side. As a result, the shaft hole (B) becomes a tapered hole, for example, with a diameter of 5 mm and a length of 1011 mm.
In the case of 1740 shaft hole, the difference in radius between the maximum circle and the maximum 4 circles is 0.
．． It can even be 1 to 0.2 mm. If such a guide pulley (A) is used, the shaft attachment will be incomplete, the frictional resistance of the thread will increase, and the life of the thread will be shortened. Therefore, after firing, we conducted a 100% inspection.
Determine whether the shaft hole (B) is greater than a specified value (for example, Q, l 1 nm), and if the taper is greater than the specified value, internally grind the shaft hole (B) with a diamond grindstone until the taper reaches the specified value. It has been corrected to be within the range. However, these operations were extremely complicated and significantly reduced productivity.
本発明は、上記事情を参酌してなされたもので、軸穴の

約１／３に短縮する。After a ceramic raw material such as alumina (A'tos) is placed in a mold, it is press-molded to obtain a cylindrical molded product (1) as shown in FIG. 2, which is then fired. The middle part of the outer peripheral surface of this cylindrical molded product (1) has a cross section of U where the thread is wound.
A circular annular groove (2) is formed coaxially. Next, a cylindrical pusher (made of a plastic such as phenol resin, polyamide resin, or fluororesin) having an outer diameter larger than the inner diameter of the shaft hole (3) of this cylindrical molded product (1) is attached.
4) Apply an adhesive (5) such as epoxy resin to the outer circumferential surface of (see FIG. 3) (see FIG. 4). This bush (4) contains a slot (6). However,
As shown in FIG. 5, a bush (4) coated with adhesive (5) is inserted into the shaft hole (3) of the cylindrical molded product (1). At this time, due to the elasticity of the slot (6), the push-up (4)
can be smoothly inserted into the shaft hole (3). Then, the adhesive (5) is solidified to integrate the push-piece (4) and the cylindrical molded product (1). In this way, even if the inner surface of the shaft hole (3) of the cylindrical molded product (1) becomes tapered or irregularly shaped due to shrinkage during firing, the bushing (4) makes it untapered and coaxial with the shaft hole (3). The shaft hole (7) can be obtained. As a result, the shaft hole (7
), the shaft attachment to the thread is perfect, the thread can be smoothly fed out, and the life of the thread can be extended. Moreover, it eliminates the need for a 100% inspection to determine whether the taper of the shaft hole (3) is within the standard value.
) is no longer necessary for internal grinding to correct the problem, and the man-hours are reduced to about 1/3.
