Description

  The present invention relates to a tool clamping device, and more particularly to a variable angle clamping device.

The basic structure of a general vise that is commercially available is mainly provided with a fixed jaw at one end, and a movable jaw that can be moved by a screw is slid on the top of the vise to fix the workpiece. The jaws and the movable jaws are clamped and fixed to make it easy to perform processing operations. However, in such a vise structure, only one workpiece can be processed by sandwiching and fixing one workpiece at a time. The work material on the vise had to be loosened and replaced, causing confusion and inconvenience in processing operations.

Further, in the conventional clamping device structure, for example, “a clamping device structure that can be clamped and positioned in both directions” of Patent Document 1, mainly two contact blocks are mainly provided, and the two contact blocks are opposed to each other. A conical conical surface is formed on each side surface, and a pressing block having the same inclination angle as the conical surface is provided between the conical surfaces of the two contact blocks. Bolts that penetrate the holding block are provided on the upper side, and spring hooks for locking the springs are provided on both side surfaces on which the springs of the corresponding contact block are provided. Side plates are respectively provided on the side surface on which the spring is provided, and a long regulation block capable of contacting the spring is formed on the two side plates so as to project. Thus, when the bolt is screwed into the through hole provided on the machine base, the bolt is moved so that the pressing block is attached at the head of the bolt, and the conical surface of the pressing block has a conical surface. Press the two abutment blocks so as to protrude toward both sides. This achieves the effect of sandwiching and positioning the workpieces on both sides at the same time, thereby enhancing the flexibility and effect of the entire sandwiching tool.
