Detailed description of the invention
Fig. 1 is the structural schematic diagram of the sleeping conversion pivot angle head of an embodiment of the present invention neutrality.
Specific embodiment
It describes in detail in the following with reference to the drawings and specific embodiments to technical solution of the present invention.
As shown in connection with fig. 1, the vertical sleeping conversion pivot angle head of the present embodiment, including input shaft 1, transmission shaft 2, main shaft 3, cabinet 4,
Main shaft shell 5, driving unit 6, gear 7 and gear ring 8.
Input shaft bore is equipped on cabinet 4 in the horizontal direction, input shaft 1 is fixed on defeated by bearing, sleeve and bearing lantern ring
Enter in axis hole, makes input shaft 1 that can carry out being freely rotated around itself circumferencial direction in input shaft bore.The input of input shaft 1
End is located at the outside of input shaft bore, for being attached with power source, for example (,) main motor or retarder, the output end of input shaft 1
It is connect with the input terminal of transmission shaft 2, so that transmission shaft 2 be driven to carry out the rotation around own axes circumferencial direction.In main shaft shell 5
Equipped with transmission axis hole and spindle hole, wherein transmission shaft 2 is fixed in transmission axis hole by bearing, and 3 axis of main shaft holds, sleeve, axis
It holds retaining ring and bearing (ball) cover is fixed in spindle hole, and the output end of transmission shaft 2 is connect with main shaft 3, thus by 2 band of transmission shaft
Dynamic main shaft 3 carries out the rotation around own axes circumferencial direction.Driving unit 6 is between cabinet 4 and main shaft shell 5, for controlling
System is between the two along the axis direction distance of transmission shaft 2.Gear 7, which is arranged, to be fixed on transmission shaft 2, and gear ring 8 is fixed on transmission shaft
In hole, and gear 7 can be engaged along the axis direction of transmission shaft 2 progress selectivity with gear ring 8 and disengaging.
When the vertical sleeping conversion pivot angle head of the present embodiment carries out main axis processing, first by power source drive input shaft 1
It is rotated；Then transmission shaft 2 is driven to be rotated in the transmission axis hole in main shaft shell 5 by input shaft 1；Finally by being driven
Axis 2 drives main shaft 3 to carry out the rotation around own axes circumferencial direction in the spindle hole in main shaft shell 5, to realize main shaft 3
Rotation processing.
When the vertical sleeping conversion pivot angle head of the present embodiment carries out the vertical sleeping conversion of main shaft, starting driving unit 6 first, by driving
