embodiment 2
Turntable is directly driven by torque motor, there is no intermediate transmission link, has realized " zero " backlass, good rigidly, easily process and assemble, easy care.The angular acceleration that torque motor can reach is higher 5～6 times than traditional worm and gear auxiliary driving.Because torque motor has high static state, dynamic load rigidity, under high speed rotary motion, still can ensure that workbench has very high positioning precision and repetitive positioning accuracy.In crossed roller bearing, cylindrical roller is arranged mutual vertically by spacing holder on the V shape groove rolling surface that is 90 °, therefore same crossed roller bearing can bear radially, axially, the load of the multiple directions such as moment.The spacing holder of crossed roller bearing can increase effective contact length of roller, and this feature has improved the bearing capacity of workbench greatly, has increased the dynamic and static rigidity of workbench and run stability.
Adopted the mode of 6 lockings, the tight masterpiece of stopping is used in the annular being connected with rotation of rotary table part and stops on tight steel plate, has reached and has both met critical the asking of stopping, and does not cause again the object of large part distortion.
The precompression that compression disk spring produces, passes to by piston rod the tight dish of stopping and compresses the tight steel plate of stopping downwards, ensures that workbench, in the time being subject to large cutting force, has the enough tight moment of stopping.When assembling, want match grinding adjusting pad (a group 6), meet 6 tight cylinders of stopping and stop when tight, the tight power size of stopping that the tight dish of stopping produces is basically identical, and the tight state lower table that ensures to stop does not produce angular displacement; Match grinding adjusting pad (one group 6), meet 6 tight cylinders of stopping and unclamp time, adjusting pad 8 and stop and have suitable gap between tight steel plate 6, gap is generally 0. 05～0. 1 mm, ensures that worktable rotary is smooth and easy.
