とともに把持部の把持する力を付与している。In an automatic tool changer that installs and stores tools between the tool magazine side of a machine tool and the machine spindle side without using a tool change arm, the tool holder gripping device usually has a pair of left and right grips. It consists of a fulcrum hole and a spring necessary to operate this grip. The grip has a semicircular fitting part that corresponds to the shape of the flange part of the tool holder to be gripped, and a locking device called a key is usually installed between the pair of grips to prevent the tool holder from rotating and swinging. will be provided. A support pin is passed through the fulcrum hole, and the support pin is connected to the magazine base so that the grip can be operated. regulates the degree of rotation and provides the gripping force to the gripping portion.

するとき、グリップの工具ホルダー嵌入部と工具ホルダ
ーフランジ当接部との間で常に滑り抵抗が発生するので
潤滑剤を施してあく必要がある。Grips, etc. that make up conventional tool holder grips are made of metal materials such as steel or cast iron, and the surface hardness of the flange of the tool holder is usually HRC58-6.
However, the surface hardness of the tool holder insertion part of the grip is lower than the surface hardness of the tool holder 7 flange part, and is usually set to IRC50-55. In general, grippers made of metal materials are heat-treated after being shaped into the grip shape in order to increase the surface hardness around the tool holder fitting part and the fulcrum hole, but it is necessary to remove the distortion caused by this heat treatment. The manufacturing process is complicated, and the unit cost of parts is high. Furthermore, when the tool holder gripper grips or detaches the tool holder, it is necessary to apply lubricant because sliding resistance always occurs between the tool holder insertion part of the grip and the tool holder flange contact part.
また、グリップに設けられた支点孔と支点ピンとの当接

It is an object of the present invention to provide a tool holder gripping tool having excellent strength.

成されることを見出した。The inventor of the present invention reduced the frictional resistance of the fitting part of the tool holder and the abutment surface of the fulcrum hole in the grip constituting the tool holder grip, making it possible to use the fulcrum part without injecting lubricating oil. As a result of intensive research in order to create an economically superior tool holder grip that simplifies the manufacturing process, the grip that makes up the tool holder grip was heated and compressed using carbon fiber-reinforced synthetic resin composite molding material. It has been found that the intended purpose can be achieved by processing the material by molding or the like.

しい。The carbon fibers used in the carbon fiber-reinforced synthetic resin composite molding material of the present invention may be either PAN-based or pitch-based, but it is necessary to use one that has been subjected to a treatment suitable for the synthetic resin used. In addition, the fiber length is generally 3 to 6 m.
Around m is used. When considering the strength of the product, the longer the fiber length is, the more advantageous it is, but it is selected appropriately depending on the shape and dimensions of the grip. In addition, the synthetic resin that is one of the components of the carbon fiber reinforced synthetic resin composite molding material used in the present invention can be either a thermosetting resin or a thermoplastic resin, but the product has considerable rigidity. Therefore, thermosetting resins such as phenolic resins and polyester resins are suitable, while thermoplastic resins include low-shrinkage engineering plastics with good oil resistance, such as polyamide resins and polyphnylene resins. Ether resins and the like are preferred.

回転揺動しないように位置決めするための治具である。In this series of operations, the grip constituting the tool holder gripping tool of the present invention is a molded product of carbon fiber reinforced synthetic resin composite material and has excellent sliding properties. The coefficient of friction with the flange portion is small and the tool holder is self-lubricating, so the tool holder can be gripped or detached without any problem without applying lubricant to the fitting portion. Furthermore, the tool holder is gripped or detached while compressing the spring 4 with the support pin 7 as the rotation axis. At this time, large friction occurs at the contact portion between the support pin 7 and the fulcrum hole 3, but in this case as well, the grip itself is a molded product of carbon fiber reinforced synthetic resin composite material, so it has sliding properties and is Even without injection, the fulcrum hole will not wear out or galling will occur. Note that the locking tool 9 provided between the pair of grips is a jig for positioning the tool holder so that it does not rotate and swing within the insertion part when the gripping tool grips the tool holder.

Lubrication, etc. was no longer necessary, abnormalities such as inability to slide due to galling did not occur, and the tool holder could be easily gripped and removed without applying lubricant at the insertion part of the grip.
更に、摩耗は従来の鋼材と比べて１０分の１以下であり
長期使用に耐えることも判明した。Furthermore, it was found that the wear was less than one-tenth that of conventional steel materials, and that it could withstand long-term use.

後処理工程は不必要であり工業的に極めて有利である。The parts such as the grip that make up the tool holder gripping tool of the present invention are molded from a carbon fiber reinforced synthetic resin composite material, so not only the fulcrum hole but also the tool holder insertion part of the grip can be integrally molded, and it is highly durable. It has excellent sliding properties and wear resistance, and unlike conventional steel materials, there is no need for lubrication during use. In addition, post-processing steps such as heat treatment after molding and removal of thermal strain, which are required in the case of steel grips, are unnecessary, which is extremely advantageous industrially.
