The specific embodiment

Further describe the utility model below in conjunction with accompanying drawing:

Extremely shown in Figure 6 as Fig. 1, swinging drilling processing unit (plant) comprises T type bent plate 1, apotting spindle 2, first locknut 3, open washer 4, model drilling body 6, dust cover 7, thrust bearing 8, packing ring 9, second locknut 10, three drill bushings 11, calibration centring means 12, wherein, an end of apotting spindle 2 is locked at workpiece 5 on the model drilling body 6 by open washer 4 by first locknut 3; The other end of apotting spindle 2 is pressed onto thrust bearing 8 on the T type bent plate 1 by packing ring 9 by second locknut 10; Model drilling body 6 is provided with index hole, matches with calibration centring means 12 and finishes circular index, location; Three drill bushing 11 static pressure are on model drilling body 6; Model drilling body 6 and dust cover 7 are separately fixed on the T type bent plate 1.

As Fig. 7, shown in Figure 8, calibration centring means 12 comprises calibration locating shaft 121, lining 122, standstill locking pin 123, spring 124 and adjusts and covers 125, one end of described calibration locating shaft 121 is cylinders that are provided with cambered surface, and calibration locating shaft 121 places lining 122; One end of calibration locating shaft 121 and an end of spring 124 join; A cylindrical end that is provided with cambered surface links to each other with model drilling body 6, and the other end of spring 124 covers 125 with adjustment and joins, and standstill locking pin 123 is fixed on the lining 122; Lining 122 is assembled together by interference fit and T type bent plate 1.

The utility model mainly is connected with drilling machine by T type bent plate, is about to T type bent plate and places on the drilling machine face.T type bent plate 1 is that element body, the apotting spindle 2 of frock is connected, makes matched in clearance with basic hole system by certain precision by axis hole with T type bent plate 1, and apotting spindle 2 can freely be turned round, one end of apotting spindle 2 is connected with thrust bearing 8, the other end is connected with model drilling body 6, on the model drilling body 6 index hole is arranged, match with indexing positioning device 12, finish circular index, location.Locknut 3, open washer 4 are finished the locking to workpiece, location, transposition that model drilling body 6 realizes workpiece, and thrust bearing 8, packing ring 9, locknut 10 assist location axles are finished the revolution location and the locking of workpiece together.Dust cover 7 is a protector, by four screws on dust cover 7 mounting angle plates 1, to reach protective actions such as dustproof, the waterproof to thrust bearing 8 apotting spindles 2, anti-bits.Drill bushing 11 is the guiding device of Workpiece boring, matches with high precision position hole on the model drilling body, finishes the guiding to the Workpiece boring position.
