Various objects in the embodiments are depicted in proportions, sizes, deformations, or displacements suitable for illustration, rather than in proportion to actual elements, which will be described together.
請參閱圖1至圖5所示，本發明提供一種工具機之刀庫改良結構，於本實施例中特指一種圓盤式之刀庫結構改良，其包含其包含一主體10、一環件20、一轉盤30以及複數刀套40，其中：Please refer to FIG. 1 to FIG. 5. The present invention provides a tool magazine improved structure of a machine tool. In this embodiment, the invention specifically refers to a disc type tool magazine improved structure, which includes a main body 10 and a ring 20. , A turntable 30 and a plurality of knife sets 40, of which:
所述主體10，其具有一軸接部11，此軸接部11呈圓柱狀而位於主體10之中心，主體10並具有一外周部12，此外周部12係於主體10之周圍所環設。於本實施例中，主體10旁架設有一驅動源13，其中包含驅動馬達以及減速機等構造(圖中未示)，而可藉由驅動源13之作動而帶動軸接部11旋轉。The main body 10 has a shaft connecting portion 11. The shaft connecting portion 11 is cylindrical and is located at the center of the main body 10. The main body 10 further includes an outer peripheral portion 12. The outer peripheral portion 12 is arranged around the main body 10. In this embodiment, a drive source 13 is provided beside the main body 10, and includes a structure (not shown) such as a drive motor and a speed reducer. The shaft connection portion 11 can be driven to rotate by the action of the drive source 13.
所述環件20，其於本實施例中具有和外周部12對應之輪廓(皆呈圓形)，且環件20係對應地設在外周部12，意即環件20是固定在外周部12 ，可視環件20和主體10為一體。惟於本實施例中，主體10是為金屬材質(鐵材、鋼材)，而環件20則為塑性材質。The ring member 20 has a contour corresponding to the outer peripheral portion 12 (all of which are circular) in this embodiment, and the ring member 20 is correspondingly provided on the outer peripheral portion 12, which means that the ring member 20 is fixed to the outer peripheral portion. 12, the ring 20 and the main body 10 can be seen as a whole. However, in this embodiment, the main body 10 is made of metal (iron, steel), and the ring 20 is made of plastic.
所述轉盤30，其以中心設在軸接部11，此時轉盤30是可以相對主體10而轉動，而前述的環件20是位在主體10和轉盤30之間。The turntable 30 is centered on the shaft connection portion 11. At this time, the turntable 30 can rotate relative to the main body 10, and the ring 20 is located between the main body 10 and the turntable 30.
所述複數刀套40，是可擺動地設在轉盤30，且複數刀套40在本實施例中於所設之轉盤30上呈環形排列。各圖中刀套40是位在初始位置而可供刀具(圖中未示)置放，當加工機欲以旋臂取刀時，刀套40可擺動90度而令刀具擺出俾供換刀，惟此動作已為習知，於此不另予贅述。於本實施例中，各刀套40皆具有一靠抵部41，各刀套40隨轉盤30轉動時以靠抵部41承靠在環件20，藉以定位各刀套40在前述的初始位置，由於刀套40隨轉盤30轉動時，其靠抵部41和所承靠之環件20必然會產生摩擦，故將靠抵部41和環件20設計為塑性材質，由於靠抵部41和環件20皆為性質相同之塑性材質，因此能減少靠抵部41和環件20間之磨耗，並且能夠降低摩擦所生之噪音。The plurality of tool sleeves 40 are swingably provided on the turntable 30, and the plurality of tool sleeves 40 are arranged in a ring shape on the provided turntable 30 in this embodiment. The tool holder 40 in each figure is in the initial position and can be placed by a tool (not shown). When the processing machine wants to take the tool with a swing arm, the tool holder 40 can swing 90 degrees to swing the tool for replacement. Knife, but this action is already known, so I wo n’t repeat it here. In this embodiment, each of the tool sleeves 40 has an abutment portion 41. When each of the tool sleeves 40 rotates with the turntable 30, the abutment portion 41 bears against the ring member 20, thereby positioning each of the tool sleeves 40 at the aforementioned initial position. As the knife cover 40 rotates with the turntable 30, the abutting portion 41 and the supporting ring member 20 will inevitably produce friction. Therefore, the abutting portion 41 and the ring member 20 are designed as plastic materials. The ring members 20 are all plastic materials of the same nature, so the abrasion between the abutment portion 41 and the ring member 20 can be reduced, and the noise caused by friction can be reduced.
較佳地，本實施例之環件20，其具有一底部21和一環牆部22，環牆部22由底部21之環周朝一側伸設，環件20於本實施例中是以底部21設在外周部12，並且以環牆部22被靠抵部41承靠。其中，本實施例之環牆部22，其於頂緣221凹設有複數溝槽222，各溝槽222內填設有潤滑脂A(如圖5所示)，此潤滑脂A又可稱為黃油或牛油，靠抵部41係承靠在複數溝槽222上，並且以各溝槽222所填設之潤滑脂A提供摩擦時之潤滑。因此，本實施例除了靠抵部41和環件20皆為性質相同之塑性材質，而可減少靠抵部41和環件20間之磨耗，並且能夠降低摩擦所生之噪音之外，進一步藉由溝槽222中可填設潤滑脂A，足令靠抵部41和環件20間之磨耗能更小，且能讓摩擦所生之噪音能更顯著地降低。Preferably, the ring member 20 of this embodiment has a bottom portion 21 and a ring wall portion 22, and the ring wall portion 22 is extended from the ring of the bottom portion 21 to one side. The ring member 20 in this embodiment uses the bottom portion 21 It is provided in the outer peripheral portion 12 and is supported by the abutting portion 41 with the ring wall portion 22. Among them, the ring wall portion 22 of this embodiment is recessed at the top edge 221 with a plurality of grooves 222, and each groove 222 is filled with grease A (as shown in FIG. 5). This grease A can also be called It is butter or butter, the abutting portion 41 bears on the plurality of grooves 222, and the grease A provided in each groove 222 provides lubrication during friction. Therefore, in this embodiment, in addition to the abutment portion 41 and the ring member 20 being plastic materials of the same nature, the abrasion between the abutment portion 41 and the ring member 20 can be reduced, and the noise caused by friction can be reduced. The groove A 222 can be filled with grease A, so that the wear energy between the abutting portion 41 and the ring 20 is smaller, and the noise generated by friction can be reduced significantly.
本實施例之環件20，其為一體射出成型，且其環牆部22之內側和底部21間具有複數補強肋23，藉以強化環牆部22和底部21間之結構強度。此外，環件20之環牆部22於外側具有複數凸耳24，各凸耳24具有一穿孔241。於本實施例中，轉盤30則於中心具有一套接部31，此套接部31具有一軸孔311，此軸孔311係對應主體10之軸接部11而設，轉盤30於主體10上組裝時，係套接部31以軸孔311設於軸接部11，俾使軸接部11轉動時可帶動轉盤30旋轉。The ring member 20 of this embodiment is integrally injection-molded, and a plurality of reinforcing ribs 23 are provided between the inside of the ring wall portion 22 and the bottom portion 21 to strengthen the structural strength between the ring wall portion 22 and the bottom portion 21. In addition, the ring wall portion 22 of the ring member 20 has a plurality of lugs 24 on the outside, and each of the lugs 24 has a perforation 241. In this embodiment, the turntable 30 has a set of connecting portions 31 at the center. The sleeve portion 31 has a shaft hole 311. The shaft hole 311 is provided corresponding to the shaft connecting portion 11 of the main body 10. The turntable 30 is on the main body 10. When assembling, the sleeve connection portion 31 is provided on the shaft connection portion 11 with a shaft hole 311, and when the shaft connection portion 11 is rotated, the turntable 30 can be rotated.
前揭靠抵部41和環件20皆為性質相同之塑性材質，而所述塑性材質為工程塑膠(POM)、尼龍(Nylon)、鐵氟龍(Teflon)、聚乙烯(PE)、聚丙烯(PP)或氯乙烯(PVC)其中之一者，或所列材質兩種以上之組合者，而於本實施例中，靠抵部41和環件20皆為工程塑膠(POM)。當然，於本發明中不排除其他類似性質之塑性材質，舉凡能達成本發明所欲達成之塑性材質者，皆屬本發明所欲保護之範疇。The front abutment portion 41 and the ring member 20 are all plastic materials of the same nature, and the plastic materials are engineering plastic (POM), nylon (Nylon), Teflon, polyethylene (PE), polypropylene (PP) or vinyl chloride (PVC), or a combination of two or more of the listed materials. In this embodiment, the abutting portion 41 and the ring member 20 are both engineering plastics (POM). Of course, other plastic materials with similar properties are not excluded in the present invention, and those who can reach the plastic materials that the invention intends to achieve are all within the scope of the present invention.
由上述之說明不難發現本發明之特點在於，各刀套40之靠抵部41和環件20皆為塑性材質，故當轉盤30被軸接部11帶動而旋轉時，刀套40以靠抵部41承靠在環件20而產生摩擦，但因本發明之靠抵部41和環件20同為塑性材質所製成，相較於習知為金屬材質之基座對為塑料之刀套有相當程度之磨損情形，且會產生明顯的噪音，本發明相對能夠減少靠抵部41和環件20間之磨耗，故能讓靠抵部41承靠於環件20時之使用壽命較長，且同為塑性材質也能有效降低摩擦所生之噪音，藉以增加刀庫之使用壽命，特別是換刀頻率高之刀庫，且能有效降低刀庫使用時之噪音。From the above description, it is not difficult to find that the feature of the present invention is that the abutting portion 41 and the ring member 20 of each blade cover 40 are made of plastic material. Therefore, when the turntable 30 is driven and rotated by the shaft connection portion 11, the blade cover 40 The abutment portion 41 bears friction on the ring member 20, but because the abutment portion 41 and the ring member 20 of the present invention are made of plastic material, compared with the conventional metal material, the base is a plastic knife. The sleeve has a considerable degree of abrasion and generates obvious noise. The present invention can relatively reduce the wear between the abutment portion 41 and the ring member 20, so that the service life of the abutment portion 41 when it bears on the ring member 20 is relatively long. It is long and the same plastic material can also effectively reduce the noise caused by friction, thereby increasing the service life of the tool magazine, especially the tool magazine with high frequency of tool change, and it can effectively reduce the noise when using the tool magazine.
此外，由於環件20設有溝槽222，操作時可於溝槽222內填設潤滑脂A，而當靠抵部41承靠於環件20時會沾有潤滑脂A，即時產生摩擦時也能藉由潤滑脂A提供潤滑，使靠抵部41和環件20間之磨耗更為減少，且靠抵部41和環件20摩擦所生之噪音降低的效果可更為顯著。In addition, since the ring member 20 is provided with a groove 222, grease A can be filled in the groove 222 during operation, and when the abutting portion 41 bears against the ring member 20, the grease A will be stained, and friction will occur immediately. Lubrication can also be provided by the grease A, so that the abrasion between the abutting portion 41 and the ring 20 is further reduced, and the noise reduction effect caused by the friction between the abutting portion 41 and the ring 20 can be more significant.
以上所舉實施例僅用以說明本發明而已，非用以限制本發明之範圍。舉凡不違本發明精神所從事的種種修改或變化，俱屬本發明意欲保護之範疇。The above-mentioned embodiments are only used to illustrate the present invention, and are not intended to limit the scope of the present invention. Various modifications or changes which do not violate the spirit of the present invention belong to the scope of the present invention.
