Description

technical field [0001] The invention belongs to the technical field of equipment manufacturing, and particularly provides a new type of numerically controlled mechanical equipment for positioning the rotation angle with high precision. Background technique [0002] Five-axis CNC machining center usually adds two rotary axes on the basis of three orthogonal linear axes to realize multi-face machining and complex curved surface machining. There are three conventional methods: one is three orthogonal linear axes plus The two-axis rotary power head is called a universal head five-axis machining center; the second is three orthogonal linear axes plus a cradle and a turntable, which is called a cradle-type five-axis machining center; the other is a three-axis machining center. The cross-linear axis plus the single-axis swing head and the single-axis turntable are called the swing-head turntable five-axis machining center. The five-axis machining of the above three methods has its ...

[0002] Five-axis CNC machining centers usually add two rotary axes to three orthogonal linear axes to realize multi-face machining and complex curved surface machining. There are three conventional methods: one is three orthogonal linear axes plus The two-axis rotating power head is called a universal head five-axis machining center; the second is three orthogonal linear axes plus a cradle and a turntable, which is called a cradle-type five-axis machining center; the other is a three-axis machining center Intersecting linear axes plus single-axis swing head and single-axis turntable are called swing head turntable five-axis machining centers. The five-axis machining of the above three methods has its own advantages and disadvantages. Universal head five-axis machining center, tool spindle The rigidity is reduced, the cutting torque of the tool is small, and the speed of the tool spindle is also limited; the method of adding a turntable to the cradle does not affect the rigidity and speed of the spindle, which is suitable for heavy cutting, but the width of the rocker arm limits the size of the workpiece; single-axis swing head and single-axis The way of the axis turntable is a compromise between the advantages and disadvantages of the first two methods. Although the limitation of the workpiece size is lifted and the rigidity of the spindle is appropriately improved, it is not very ideal.
