Description of drawings
Accompanying drawing 1 is the structural representation of the specific embodiment of the invention.
Accompanying drawing 2 is the vertical view of the specific embodiment of the invention.
Accompanying drawing 3 turns round the structural representation of centering machine for the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
A kind of numerical control floor formula boring and milling machine is used rotary table, comprises rotary slide base 1, is installed in mandrel 2 and work top 3 on the rotary slide base 1, and work top 3 is installed on the rotary slide base 1 through mandrel 2.
The center of work top 1 is provided with the revolution centering machine, and this revolution centering machine comprises that endoporus is the double-row conical bearing 4 of taper hole and is sleeved on the tapered sleeve 5 on the double-row conical bearing 4, and double-row conical bearing is sleeved on the mandrel 2.Work top 3 centers are provided with a ring-type T type groove, and double-row conical bearing 4 is installed in the T type groove with tapered sleeve 5.An angle orientation circle grating 10 also is installed in the T type groove, the angle of revolution is accurately fed back, the rotating accuracy error is little.
Be provided with two gear clearance elimination slew gears between rotary slide base 1 and the work top 2; Be used to drive the revolution of work top; This pair gear clearance elimination slew gear comprises two gear clearance elimination reductors 6 and gear ring 7; Two gear clearance elimination reductors 6 are fixedly mounted on the rotary slide base 1, and gear ring 7 is fixed on the work top 3, and two output gears 8 of two gear clearance elimination reductors 6 are meshed with gear ring 7.
