The specific embodiment
For understanding the structure of cnc boring and milling machine new index Work turning table in depth, be described as follows in conjunction with Fig. 1:
Cnc boring and milling machine new index Work turning table, comprise upper saddle 9, pull bar 2, concave sphere packing ring 1, protrudent sphere packing ring 2 and Work turning table 12, place Work turning table 12 on the upper saddle 9, pull bar 2 upper ends cover has concave sphere packing ring 1, protrudent sphere packing ring 2, and is fixed in the Work turning table 12; Work turning table 12 bottoms arrange unilateral thrust roller bearing 13, unilateral thrust roller bearing 13 between Work turning table 12 and upper saddle 9, Work turning table 12 by unilateral thrust roller bearing 13 as guide supporting on upper saddle 9; Set 4 retaining mechanisms of diameter distribution at relative Work turning table 12 centres of gyration, pull bar 2 is connected with retaining mechanism, and by pull bar 2 motions, retaining mechanism cooperates unilateral thrust roller bearing 13 that Work turning table 12 is held tightly on upper saddle 9.Described retaining mechanism comprises oil-in 4, large piston 5, valve piston 11, cylindrical spring 7, flat spring 8; Large piston 5 is connected with valve piston and is connected with pull bar 3 respectively, and cylindrical spring 7 is connected with large piston 5, and flat spring 8 is connected with valve piston 11, cylinder body 10.Described oil cylinder is the single effect formula; The reverse movement of large piston 5 is realized that by cylindrical spring 7 the reverse movement of valve piston 11 is realized by flat spring 8.Described large piston 5, the material of valve piston 11 are No. 45 steel, and the material of Work turning table 12 is cast iron.When holding Work turning table 12 tightly, oil cylinder is through oil-in 4 fuel feeding, and valve piston 11 is the top upwards, and large piston 5 is used in masterpiece on the Work turning table 12 by pull bar 3, concave sphere packing ring 1 and protrudent sphere packing ring 2 toward drop-down, and valve piston 11 and pull bar 3 are held Work turning table 12 tightly jointly.When Work turning table 12 needs transposition, the oil cylinder draining, under the effect of cylindrical spring 7 and flat spring 8, large piston 5, valve piston 11 resets respectively, unclamps locking, Work turning table 12 free circular indexs.
Work turning table adopts the bearing element guide supporting, and locking mode adopts and holds tightly, and effect is comparatively desirable.At this moment, the locking machine member participates in locking by a driving link, and becoming is that two driving links participate in locking.Being that Work turning table is implemented to compress before the improvement, is that Work turning table is implemented to hold tightly after the improvement.Because piston material is No. 45 steel, the turntable material is cast iron, and coefficient of friction was larger when this bi-material engaged, and the frictional force of generation will be much larger than the former, the Work turning table reliable lock.In calibration locking process, oil cylinder piston will be done trace relative to cylinder body and move, and therefore, must stay the gap during design.In the machine cut process, this gap can cause trembling of Work turning table.The flat spring that adds is except playing after Work turning table is removed locking, and outside valve piston being thrown off reset, another effect is trembling of bringing when preventing from cutting, and reduces to greatest extent it to the impact of cutting quality.
As Work turning table, should possess certain braking moment is arranged, also will possess simultaneously has enough resistance to capsizings.The size of braking moment depends on the active force of valve piston, and resistance to capsizing then depends on the pressure differential of large valve piston, utilizes this difference that the moment of pivot is overcome external tilting moment.The characteristics of Novel work turntable are, the pressure differential that piston produces of utilizing two diameter not wait in the design of oil cylinder reaches this purpose.
The cnc boring and milling machine market capacity is large, and the transformation of guide supporting mode is conducive to mass production.The change of locking mode improves functional reliability, and easy to maintenance, economic benefit and social benefit are considerable.
