Horizontally sliding milling unit for nut milling machine

The utility model relates to a mill-cut device, which can slide horizontally for a screw cap mill-cut machine. The utility model is mainly provided with a screw gear at the backside of a manufacture axle of a mill-cut machine additionally, the screw gear engages with another slave screw gear which pivots at one side carrying plate of a machine body and rolls, a slave screw gear coaxial rotary table is provided with a chute preliminarily, a slider is provided in the chute, the slider is linked with a cardan connecting bar assembly that is fixedly arranged on the machine base, the bottom of the machine body is provided with a pair of sliding rails. When the motor drives the manufacture axle and causes the screw gear to drive the slave screw gear to roll, the connecting bar guiding machine body does reciprocal sliding on the support of the sliding rail along with the revolution of the rotary table, thereby avoiding destroying the thread structure and limiting the manufacture depth of the thread during the manufacture process.
