X-axis driving structure 312 include the first helical gear 3120, the first X-axis feeding motor 3121, the second helical gear 3122,
Second X-axis feeds motor 3123 and X-axis guide rail sliding block 3124；X-axis guide rail sliding block 3124 is arranged at the side of planker 311, and X-axis is led
Rail sliding block 3124 is used to guide movement of the planker 311 in lathe bed 100, the first helical gear 3120 and the first X-axis feeding motor 3121
Transmission coordinates, and the second helical gear 3122 and the feeding transmission of motor 3123 of the second X-axis coordinate, the first helical gear 3120, the second helical teeth
Wheel 3122 is located at the same side of planker 311 with X-axis guide rail sliding block 3124 and can coordinated with the rack of lathe bed 100.
X-axis driving structure 312 includes three kinds of motion states：First state, the second state and the third state.First state is
The positive feeding state of X-direction, the second state are feed reversing state, and the third state is feed reverse state.First state
Under, the first helical gear 3120 turns clockwise with the second helical gear 3122, the first helical gear 3120 and second under the second state
3122 equal rotate counterclockwise of helical gear, under the third state, the second helical gear 3122 keeps turning clockwise, the first helical gear 3120
Rotate counterclockwise, first state can mutually be switched with the second state by the third state.Particularly, when needing from the second state
When being converted into first state, the third state is opposite, i.e. the first helical gear 3120 keeps rotate counterclockwise, the second helical gear
3122 are changed into and turn clockwise, and then the first helical gear 3120 becomes to turn clockwise again, the conversion of completion status.
Detailed, the first helical gear 3120 and the second helical gear 3122 are flange-mount type helical gear, the first helical gear
3120 feed the transmission of motor 3121 by the X-axis of planetary reduction gear 3,126 first coordinates, and the second helical gear 3122 passes through planetary reduction gear
The feeding transmission of motor 3123 of the X-axis of device 3,126 second coordinates.

When processing stations unit 300 needs feeding, the feeding motor 3121 and second X-axis feeding 3123 equal dextrorotation of motor of the first X-axis
Turn, X-axis driving structure 312 is first state, and now, the first helical gear 3120 and the second helical gear 3122 are the left flank of tooth and tooth
The right flank meshing contact of bar, 1.5-2 times of single Motor torque can be exported.The feeding that commutates is needed in processing stations unit 300
When, the second helical gear 3122 keeps direction of rotation constant, and the first helical gear 3120 drives from rotate counterclockwise, X-axis is changed into clockwise
Dynamic structure 312 is the third state, and now, the left flank meshing contact of the right flank of tooth and rack of the first helical gear 3120, first is oblique
The helical gear 3122 of gear 3120 and second is in the state for keeping tension force, processing stations unit 300 commutate caused by gap quilt
Eliminate.The second helical gear 3122 is contributed also from rotate counterclockwise is changed into clockwise together with the first helical gear 3120 afterwards, and then
Processing stations unit 300 enters the second state from the third state, realizes that opposite direction moves.
In this way, the drive gap between the first helical gear 3120 and rack, the second helical gear 3122 and rack can obtain
Eliminate, ensure transmission accuracy, also ensured positioning precision, even if there is mechanical wear, can also the gap that disappears have been completed by above-mentioned action,
It is very reliable.
