The most important of those attachments are a s ingl e - spindle d rilling attach ment and a singl e - spindle threading attachment. In addition, the following attachments can be s upplied on request: 1 . A two - spindle centering- d rilling attachment. 2 . A two - spindle combined drilling and threading attachment. 3 . A three - spindle combined attachment for d rilling and threading on two diamete rs . 4 . A slotting attachment . 5 . A n attachment for reducing the travel o f rocke r tools. 6 . A n attachment for tap e r turning and for the automatic retraction of the drill at deep drilling. 7 . A n attachment for automatic s toppage i n case o f thread stripping . 8 . A back- drilling attachm ent. 9. A reces sing attachment. A two - spindle attachment for centering and d rilling deep holes of small diameter is s hown in Figure 1 3 . The nonrotating centering spindle ( 1 ) is fed axially by the cam (4 ) through the lever ( 3 ) . The drilling spindle (2 ) i s fed forward b y a s p ring, and i s withdrawn by the cam ( 5 ) through the lever (6 ) . If repeated retractions of the spindle are neces sary to remove chips and cool the drill, the pus h cam (8 ) , which contacts the pin (7 ) of the lever ( 6 ), is ins talled. The cam (8 ) is rotated by (see the kinematic s cheme in Figure 5 ) . The success ive shifting of spindles is performed by cam (9). Various attachm ents are used fo r thread cutting. A c ombined two - spindle drilling - threading attachment is shown in Figure 1 4 . The d rilling spindle of the attachment (not shown i n the d rawing) i s ac tuated by the threading spindle through a gear pair ( 1 ) and can be locked so that it can move in the axial direction only. 109 |
