Description

本考案は、製造コストが比較的安い熱膨張工具ホルダーに関する。   The present invention relates to a thermal expansion tool holder that is relatively inexpensive to manufacture.

図３、４に示すように、従来の熱膨張工具ホルダーは、円盤状の本体３０と、シャフト接続用スリーブ３１と、工具接続用スリーブ３２とを含む。シャフト接続用スリーブ３１は、円錐状であり、本体３０の第１の側部に形成され、該第１の側部から伸びる。シャフト接続用スリーブ３１は、該シャフト接続用スリーブの本体３０と反対側に位置する端部に設けられたシャフト保持用孔を有し、前記熱膨張工具ホルダーがシャフトとともに回転可能となるように該シャフトに接続される。工具接続用スリーブ３２は、円錐状であり、本体３０の第２の側部に形成され、該第２の側部から伸びる。工具接続用スリーブ３２は、該工具接続用スリーブの本体３０と反対側に位置する端部に設けられシャフト接続用スリーブ３１の前記シャフト保持用孔と連通する工具保持用孔３３を有する。   As shown in FIGS. 3 and 4, the conventional thermal expansion tool holder includes a disk-shaped main body 30, a shaft connection sleeve 31, and a tool connection sleeve 32. The shaft connecting sleeve 31 has a conical shape, is formed on the first side portion of the main body 30, and extends from the first side portion. The shaft connecting sleeve 31 has a shaft holding hole provided at an end located on the opposite side to the main body 30 of the shaft connecting sleeve, and the thermal expansion tool holder is rotatable with the shaft. Connected to the shaft. The tool connecting sleeve 32 has a conical shape, is formed on the second side portion of the main body 30, and extends from the second side portion. The tool connecting sleeve 32 has a tool holding hole 33 that is provided at an end portion of the tool connecting sleeve opposite to the main body 30 and communicates with the shaft holding hole of the shaft connecting sleeve 31.

前記熱膨張工具ホルダーの使用時、工具接続用スリーブ３２の工具保持用孔３３に切断工具のような工具が挿入され、前記熱膨張工具ホルダーは熱せられる。工具接続用スリーブ３２が熱膨張すると、前記工具は、工具保持用孔３３に強固に保持され、被加工品の切断や回転のために前記熱膨張工具ホルダーとともに回転される。異なる作業条件のために異なる工具を前記熱膨張工具ホルダーに取り付けまた取り外すため、前記熱膨張工具ホルダーは、繰り返し熱せられる必要があり、通常、熱間鍛造型用の合金鋼のような、熱膨張率が高い合金材料で作られている。このため、前記熱膨張工具ホルダーの製造コストが高くつく。   When the thermal expansion tool holder is used, a tool such as a cutting tool is inserted into the tool holding hole 33 of the tool connection sleeve 32, and the thermal expansion tool holder is heated. When the tool connecting sleeve 32 is thermally expanded, the tool is firmly held in the tool holding hole 33 and rotated together with the thermally expanded tool holder for cutting and rotating the workpiece. In order to attach and remove different tools to and from the thermal expansion tool holder for different working conditions, the thermal expansion tool holder needs to be heated repeatedly, usually with a thermal expansion like alloy steel for hot forging dies. Made of high rate alloy material. For this reason, the manufacturing cost of the said thermal expansion tool holder is expensive.

本考案は、前記した問題を改善する熱膨張工具ホルダーを提供する。本考案の目的は、製造コストを低減することができる熱膨張工具ホルダーを提供することである。   The present invention provides a thermal expansion tool holder that ameliorates the aforementioned problems. The objective of this invention is providing the thermal expansion tool holder which can reduce manufacturing cost.

本考案に係る熱膨張工具ホルダーは、本体と、円錐状のシャフト接続用スリーブと、円錐状の工具接続用スリーブとを含む。前記本体は第１の側部と第２の側部とを有する。前記シャフト接続用スリーブは、前記本体の前記第１の側部に形成され、該第１の側部から伸びる。前記シャフト接続用スリーブは、該シャフト接続用スリーブの前記本体と反対側に位置する端部に設けられたシャフト保持用孔を有する。前記工具接続用スリーブは前記本体の前記第２の側部から伸びる。前記工具接続用スリーブは、該工具接続用スリーブの前記本体と反対側に位置する端部に設けられ前記シャフト接続用スリーブの前記シャフト保持用孔と連通する工具保持用孔を有する。前記工具接続用スリーブは、前記本体と強固にかつ一体的に結合された別個の部材からなる。前記本体及び前記シャフト接続用スリーブを形成する材料は、前記工具接続用スリーブを形成する材料と異なる。   A thermal expansion tool holder according to the present invention includes a main body, a conical shaft connecting sleeve, and a conical tool connecting sleeve. The body has a first side and a second side. The shaft connecting sleeve is formed on the first side of the main body and extends from the first side. The shaft connecting sleeve has a shaft holding hole provided at an end portion of the shaft connecting sleeve located on the side opposite to the main body. The tool connecting sleeve extends from the second side of the body. The tool connecting sleeve has a tool holding hole provided at an end portion of the tool connecting sleeve opposite to the main body and communicating with the shaft holding hole of the shaft connecting sleeve. The tool connecting sleeve is formed of a separate member that is firmly and integrally coupled to the main body. The material forming the main body and the shaft connecting sleeve is different from the material forming the tool connecting sleeve.

本考案の他の目的、利点及び新規な特徴は、添付の図面に関する以下の詳細な説明からより明らかになる。   Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

図１、２に示すように、熱膨張工具ホルダー１０は、本体１１と、シャフト接続用スリーブ１２と、工具接続用スリーブ２０とを含む。本体１１は、円盤状であり、第１の側部と、第２の側部と、外面と、環状溝１１１と、位置決め用ノッチ１１２と、Ｖ字状ノッチ１１３とを有する。環状溝１１１は、本体１１の前記外面に形成され、Ｖ字状の断面形状を有する。位置決め用ノッチ１１２は、本体１１の前記外面に放射方向に形成され、環状溝１１１と連通している。Ｖ字状ノッチ１１３は、本体１１の前記外面に放射方向に形成され、環状溝１１１と連通し、位置決め用ノッチ１１２から間隔を置かれている。本体１１は、該本体の前記第２の側部に形成され該第２の側部から伸びる管状のスリーブ取付部１３を有する。   As shown in FIGS. 1 and 2, the thermal expansion tool holder 10 includes a main body 11, a shaft connection sleeve 12, and a tool connection sleeve 20. The main body 11 has a disk shape, and includes a first side portion, a second side portion, an outer surface, an annular groove 111, a positioning notch 112, and a V-shaped notch 113. The annular groove 111 is formed on the outer surface of the main body 11 and has a V-shaped cross-sectional shape. The positioning notch 112 is formed radially on the outer surface of the main body 11 and communicates with the annular groove 111. The V-shaped notch 113 is radially formed on the outer surface of the main body 11, communicates with the annular groove 111, and is spaced from the positioning notch 112. The main body 11 has a tubular sleeve mounting portion 13 formed on the second side portion of the main body and extending from the second side portion.

シャフト接続用スリーブ１２は、円錐状であり、本体１１の前記第１の側部に形成され、本体１１の前記第１の側部から伸びる。シャフト接続用スリーブ１２は、該シャフト接続用スリーブの本体１１と反対側に位置する端部に設けられたシャフト保持用孔１４を有する。   The shaft connecting sleeve 12 has a conical shape, is formed on the first side portion of the main body 11, and extends from the first side portion of the main body 11. The shaft connecting sleeve 12 has a shaft holding hole 14 provided at an end located on the opposite side of the main body 11 of the shaft connecting sleeve.

工具接続用スリーブ２０は、円錐状であり、本体１１の前記第２の側部から伸びる。好ましくは、工具接続用スリーブ２０は本体１１のスリーブ取付部１３に強固に接続されている。工具接続用スリーブ２０は、該工具接続用スリーブの本体１１と反対側に位置する端部に設けられシャフト接続用スリーブ１２のシャフト保持用孔１４と連通する工具保持用孔２１を有する。工具接続用スリーブ２０は、本体１１のスリーブ取付部１３と溶接で強固にかつ一体的に結合された別個の部材である。本体１１及びシャフト接続用スリーブ１２を形成する材料は、工具接続用スリーブ２０を形成する材料と異なる。好ましくは、工具接続用スリーブ２０は、熱間鍛造型用の合金鋼のような、熱膨張率が高い合金材料で作られている。本体１１及びシャフト接続用スリーブ１２は、クロムモリブデン鋼又はニッケルクロムモリブデン鋼で作られている。本体１１及びシャフト接続用スリーブ１２の材料費は工具接続用スリーブ２０の材料費より安いため、熱膨張工具ホルダーの製造コストを低減することができる。   The tool connecting sleeve 20 has a conical shape and extends from the second side portion of the main body 11. Preferably, the tool connecting sleeve 20 is firmly connected to the sleeve mounting portion 13 of the main body 11. The tool connecting sleeve 20 has a tool holding hole 21 provided at an end portion of the tool connecting sleeve opposite to the main body 11 and communicating with the shaft holding hole 14 of the shaft connecting sleeve 12. The tool connecting sleeve 20 is a separate member that is firmly and integrally coupled to the sleeve mounting portion 13 of the main body 11 by welding. The material forming the main body 11 and the shaft connecting sleeve 12 is different from the material forming the tool connecting sleeve 20. Preferably, the tool connecting sleeve 20 is made of an alloy material having a high coefficient of thermal expansion, such as alloy steel for a hot forging die. The main body 11 and the shaft connecting sleeve 12 are made of chromium molybdenum steel or nickel chromium molybdenum steel. Since the material cost of the main body 11 and the shaft connecting sleeve 12 is lower than the material cost of the tool connecting sleeve 20, the manufacturing cost of the thermal expansion tool holder can be reduced.
