Detailed description of the invention
Brief description operation principle.
As described in Figure 2, upper grip body 1 self is rotated when automatically entering silk and is rotated and is added silk by the lower retained part of power transmission shaft 2 drive.Peace holds eccentric tie-plate 7 in retained part makes lower chuck body 9 depart from original central axis apart from 1.25mm, then while regulating high scale dish to 45 °, make 2 ° of lower chuck body 9 beats, the resultant effect producing due to the radial disbalance of lower chuck body 9 and axial-shift angle is exactly that the real work initial point of wire electrode 17 in rotation process (determined with hiccough projection on display) apart from lower filament mouth end points 2.5mm place below lower filament mouth 10, and then above work origin, can to process tapering be the positive cone spray orifice of 2 °.Below work origin, can process tapering and be the back taper spray orifice of 2 °.
Under original state, high scale dish 12 is 0 ° of position, and lower chuck body 9 central axis are parallel with rotation; When rotation 12 to 45 ° of positions of high scale dish, 2 ° of the overall beats of lower chuck body 9.Due to the resultant effect of 2 ° of lower chuck body 9 deviation distance 1.25 mm and beats be exactly the real work initial point of wire electrode 17 in rotation process below lower filament mouth 10 apart from lower filament mouth end points 2.5mm place, and then can to process tapering above work origin be the positive cone spray orifice of 2 °, below work origin, can process tapering and be the back taper spray orifice of 2 °.
Fig. 5 is the partial enlarged drawing of this mechanism processing belt tapering spray orifice, can process the spray orifice size of different size according to the wire electrode of each specification.By upper and lower displacement processome relatively with the position of work origin and then can to process tapering be the spray orifice of ± 2 °.
Fig. 7 is the not partial enlarged drawing with tapering spray orifice of processing, can comprehensively compare with this mechanism processing belt tapering spray orifice (shown in Fig. 6).This mechanism can process tapering spray orifice, and economically feasible.
