Force bearing bar is connected with the turntable for fixing lathe balance staff.
Preferably, the middle position of two mounting grooves is provided with revolving platform, and the free end of the revolving platform passes through on turntable
The centre bore opened up.
Preferably, ball screw assembly, includes lead screw, one end of lead screw and the output axis connection of motor, and the other end is connected with axis
It holds.
Preferably, working body is sleeved on lead screw, and feed screw nut is provided between lead screw, feed screw nut and working body
Between be interference fitted, meanwhile, lead screw and feed screw nut constitute ball screw assembly,.
Preferably, two straight troughs being arranged symmetrically with turntable center are offered on turntable, two force bearing bars correspond to force bearing bar
It is mounted in straight trough, and the diameter of force bearing bar is equal with the groove width of straight trough.
Compared with prior art, the utility model has the beneficial effects that
The retaining mechanism of a kind of lathe balance staff provided by the utility model, using working body along ball screw assembly, rectilinear path
Start and stop realize the rotation and locking of turntable, wherein what locking function relied on is the good stop performance of ball screw assembly, when
After motor stalls, working body stop, at this point, rotating torque caused by the external force that processing generates is applied on turntable, thus
It being applied on two force bearing bars indirectly, force bearing bar is constrained jointly by ball screw assembly, and guide rail, according to the characteristic of ball screw assembly,
What ball screw assembly, can most be born is the power of axial direction, and guide rail can then assist ball screw assembly, to bear radial force and torsion
Square, therefore, this retaining mechanism can carry biggish rotating torque, and not need to index, and realize the stepless mechanical lock of pivot angle
Tightly.
Further, the revolving platform of setting, the centre of gyration that ensure that turntable are consistent with the axle center of rotating shaft.

Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
As shown in Figure 1 and Figure 2, the retaining mechanism of a kind of lathe balance staff provided by the utility model, including slide unit 1, working body
2, lead screw 3, guide rail 4, shaft coupling 5, motor 6, feed screw nut 7, force bearing bar 8, rotating shaft 9, bearing 10 and turntable 11, wherein sliding
Platform 1 is mounted on machine pillar 12, and specifically, an end face of slide unit 1 offers groove, and machine pillar 12 is embedded in the groove
It is interior, it is matched with groove；The other end of slide unit 1 is opened up there are two mounting groove, the middle position of boss between two mounting grooves
It is provided with rotating shaft 9, rotating shaft 9 plays certralizing ability, guarantees that the centre of gyration of turntable is consistent with rotating shaft axle center.
Motor 6 is mounted in two mounting grooves, the output shaft of the motor 6 is connect by shaft coupling 5 with lead screw 3, silk
The free end of thick stick 3 is equipped with bearing 10, meanwhile, it is connected with feed screw nut 7 on lead screw 3, forms ball screw assembly,.
The feed screw nut 7 is mounted in the first mounting hole opened up on working body 2, is interference fitted with the first mounting hole；
