| 摘要 |
The invention concerns an apparatus for the tightening of non-revolving objects (6), which has a named section or axis (5) with a polygonal lateral section. The apparatus (1) has a tightening body (2) with a tightening chamber (3) polygonal in a lateral section and formed inside the tightening body to receive the named section or axis (5) as well as inside the tightening chamber (3). For the fastening of the named section or axis (5) at least at axis X and Y and in relation to its angular position, a first and second plate is formed (11, 12) mutually separated between them and which protrude from a first internal wall (7) of the tightening chamber (3) and on the other from a third plate (13) placed in a second adjacent internal wall (8) of the tightening chamber (3). The means of tightening i.e. in the form of a tightening screw (16) is placed at least opposite the plates (11, 12 and 13) in such a way that it tightens the named section or axis (5) onto the plates (11, 12 and 13). The apparatus is advisable for use as a means of tightening of electrodes and electrodes for electro-corrosive processing machines in which it is required at high level of precision even in repeated fastenings and tightenings. |
