工具機之夾持裝置Tooling device

本新型係關於一種工具機,特別係關於一種工具機之夾持裝置。The present invention relates to a machine tool, in particular to a clamping device for a machine tool.

工具機為近代社會工業發展不可或缺的重要推手,一般之工具機通常用於精密切削金屬以產生其他機器或加工的金屬零件,為了加工工件,工具機在工件和刀具間係呈現相互運動,已達加工之效,工具機一般可用以成形、切削和連接。The machine tool is an indispensable driving force for the development of the modern social industry. The general machine tool is usually used to precisely cut metal to produce other machines or machined metal parts. In order to machine the workpiece, the machine tool moves between the workpiece and the tool. Machine tools have generally been used for forming, cutting and joining.

大部分之工具機因任務需求皆配置有一夾頭供以夾設待加工的工件,習知工具機之夾頭大部分為三爪式或四爪式的夾頭,如圖1所示,其包括一夾頭本體40及三爪部41,各該爪部41係可位移的設置於該本體40,各該爪部40之間形成一夾持空間42,藉由位移各該爪部41之位置以控制該夾持空間42的大小,進而夾持各種尺寸的工件;Most of the machine tools are equipped with a chuck for the workpiece to be machined. The chuck of the conventional machine tool is mostly a three-jaw or four-jaw type chuck, as shown in Figure 1. The chuck body 41 and the three-claw portion 41 are disposed, and the claw portions 41 are displaceably disposed on the body 40. A clamping space 42 is formed between each of the claw portions 40, and the claw portions 41 are displaced by the claw portions 41. Position to control the size of the clamping space 42, thereby clamping workpieces of various sizes;

工具機於加工時,以磨床為例,係藉由該爪部41夾持待加工之工件,並驅使該夾頭本體40旋轉,以帶動工件旋轉,再藉由磨床之一砂輪對待加工之工件進行加工,惟,習知夾頭於夾固工件並旋轉的同時,由於僅由各該爪部41單點夾設工件,是以不可避免的將產生細微之晃動及偏差,進而降低加工之品質,是以,需要一種能夠降低晃動、減少加工誤差以提升加工品值之工具機之夾持裝置。When the machine tool is used for machining, the grinding machine is taken as an example, and the workpiece to be processed is clamped by the claw portion 41, and the chuck body 40 is driven to rotate to drive the workpiece to rotate, and then the workpiece to be processed by one grinding wheel of the grinding machine is used. The processing is performed. However, while the conventional chuck is used to clamp the workpiece and rotate, since only the workpiece is sandwiched by the claw portions 41 at a single point, it is inevitable that fine sway and deviation will be generated, thereby reducing the quality of the processing. Therefore, there is a need for a clamping device for a machine tool that can reduce sloshing and reduce machining errors to increase the value of the processed product.

本新型提供一種工具機之夾持裝置,其主要目的係提供一種能夠降低晃動、減少加工誤差以提升加工品值之工具機之夾持裝置。The present invention provides a clamping device for a machine tool, the main purpose of which is to provide a clamping device for a machine tool capable of reducing sloshing and reducing machining errors to increase the value of the workpiece.

為達前述目的,本新型工具機之夾持裝置,包括:For the above purposes, the clamping device of the new machine tool comprises:

一座體,具有一固定座及一滑移座,該滑移座係面對該固定座,該滑移座與該固定座間隔一距離,定義該固定座延伸至該滑移座之方向為一徑向,該固定座係固定不動,該滑移座係可沿著徑向位移;a body having a fixed seat and a sliding seat, the sliding seat facing the fixing seat, the sliding seat is spaced apart from the fixing seat, and defining a direction in which the fixing seat extends to the sliding seat is Radially, the fixed seat is fixed, and the sliding seat can be displaced along the radial direction;

至少三樞轉件,係可樞轉的設置於該座體,該些樞轉件供以夾持一工件,該工件係設置於該些樞轉件之間,至少一個該樞轉件係設置於該滑移座,至少一個該樞轉件係設置於該固定座;以及At least three pivoting members are pivotally disposed on the seat body, the pivoting members are configured to clamp a workpiece, the workpiece is disposed between the pivoting members, and at least one of the pivoting members is disposed At the sliding seat, at least one of the pivoting members is disposed on the fixing base;

一驅動裝置,與至少一個該樞轉件動力連接,該驅動裝置係用以帶動該樞轉件旋轉。A driving device is coupled to at least one of the pivoting members for driving the pivoting member to rotate.

由前述可知,本新型工具機之夾持裝置主要係藉由使該些樞轉件夾持待加工之工件,再由該驅動裝置驅動該樞轉件,帶動該工件旋轉進而使該工件能夠於被該些樞轉件夾持之同時穩定的旋轉,由於本新型工具機之夾持裝置係由至少三個樞轉件相互配合夾持工件,是以能夠抵銷晃動以達平衡之狀態,使該工件於加工時更佳的穩固,藉此達成提供一種能夠降低晃動、減少加工誤差以提升加工品值之工具機之夾持裝置之目的。It can be seen from the foregoing that the clamping device of the new type of machine tool mainly drives the workpiece to be processed by the pivoting member, and then the pivoting member is driven by the driving device to rotate the workpiece to enable the workpiece to be Simultaneously rotating by the pivoting members, since the clamping device of the new type of machine tool is configured to hold the workpiece by at least three pivoting members, it can offset the shaking to achieve balance. The workpiece is better stabilized during processing, thereby achieving the purpose of providing a clamping device for a machine tool capable of reducing sloshing and reducing machining errors to increase the value of the workpiece.
