MECHANICAL HYDRAULIC FASTENING DEVICE 2 Sheets-Sheet 1 INVENTOR. FRANZ ARNOLD WMMBMMMW ATTORNEYS United States Patent 3,147,002 MEQHANICAL-HYDRAULIC FASTENING DEVICE Franz Arnold, Schwangauerstr. 1, Hohenschwangau, Fussen, Germany Fiied Nov. 22, 1961, Ser. No. 154,217 Claims priority, application Germany Nov. 23, 1960 8 Claims. (tCl. 26924) This invention relates to a mechanical-hydraulic fastening device for the fixing of work pieces, tools and the like, in which a fastening block is fed to the work piece by the rotation of a tightening spindle and then the displacement of a primary piston in a pressure space generates a hydraulic pressure which produces the fixing pressure of the block via a secondary piston.
机械液压夹紧机构2 Sheets-Sheet 1发明家。弗朗兹·阿诺德WMMBMMMW律师3147002年美国专利MEQHANICAL-HYDRAULIC紧固装置弗朗兹·阿诺德Schwangauerstr。1,摄影,富森德国Fiied 11月22日,1961年,爵士。154217号索赔优先级,应用德国1960年11月23日8索赔。(tCl。26924)这项发明与机械液压夹紧机构工作的固定件、工具等,紧固块美联储收紧的工件的旋转主轴,然后主活塞的位移空间生成一个液压压力产生的固定压块通过二级活塞。
In a known fastening device of this type, in the form of a vice, the whole hydraulic mechanism, viz. pressure space and primary and secondary pistons, is arranged in the interior of the vice or at the inner end of the tightening spindle. This requires a complicated and expensive special construction. The object of the invention is to provide a mechanical-hydraulic fastening device of simple construction which permits the incorporation of the hydraulic mechanism in the fastening device or vice of normal construction without appreciable alteration thereof.
在这种类型的一个已知的固定装置,在副的形式,整个液压机制、空间和中小学活塞的压力,所安排的内部缺陷或在内部紧缩主轴。这需要一个复杂的和昂贵的特殊结构。发明的目的是提供一种结构简单的机械液压夹紧机构允许的紧固设备或副液压机制的正常建设没有明显的改变。
In accordance with the invention the pressure space together with the primary and secondary pistons are arranged in the end of the tightening spindle which is of enlarged diameter and within this end of the spindle there is arranged a bolt which is rotatable by means of a hand crank or the like and which can screw in an internal screw thread at the end of the spindle and the end of which bears on the primary piston.
依照本发明的压力空间一起中小学活塞被安排在紧缩的结束主轴的直径增大,结束在这个轴有安排一个可旋转的螺栓通过手动曲柄或类似的,可以在一个内部螺纹螺杆末端的主轴和结束的熊在主活塞。
This new construction provides, compared with the known construction, an appreciable simplification since the whole of the hydraulic mechanism is arranged solely in the spindle, at the outer end thereof. This has the advantage that the normal mechanical fastening device can be changed to a mechanical-hydraulic fastening device without appreciable alteration, viz. solely by exchanging the tightening spindle.
这个新建筑提供,与已知的建筑相比,一个明显的简化以来整个液压机制安排单独的轴,外端。这样做的优势在于正常的机械固定装置可以改变机械液压夹紧机构没有明显的改变,仅仅通过交换所收紧主轴。
Further details of the invention and the advantages thereof will now be described with reference to the embodiments of the invention shown by way of example in the accompanying drawings, in which is a vertical longitudinal section through a mechanical-hydraulic vice,
进一步的细节描述的发明及其优势将参照发明的化身所附图纸显示的示例中,是一个垂直纵切片通过机械
