Abstract
A rotary table is adapted to drive rotation of a fixture, and includes first and second mounting seats, first and second spindles respectively disposed in the first and second mounting seats, and a motor unit including main and auxiliary driving motors. The motor unit is operable in a first mode, where the main driving motor directly drives rotation of the first spindle and the auxiliary driving motor is not actuated, and in a second mode, where the auxiliary driving motor cooperates with the main driving motor to drive rotation of the first and second spindles so as to deliver a torque which is larger than that delivered in the first mode to the fixture to drive rotation of the fixture.
Claims10
A rotary table adapted for use in a computer numerical control (CNC) machine that includes a fixture to drive rotation of the fixture, the fixture having opposite first and second ends, said rotary table comprising:
- a first mounting seat defining a first space;
- a first spindle disposed in said first space, rotatable about an axis, and securely connected to the first end of the fixture;
- a second mounting seat spaced apart from said first mounting seat along the axis and defining a second space;
- a second spindle disposed in said second space, rotatable about the axis, and securely connected to the second end of the fixture;
- and
- a motor unit including a main driving motor that is directly connected to said first spindle so as to directly drive rotation of said first spindle, and an auxiliary driving motor that is for driving rotation of said second spindle,
- said motor unit being operable in a first mode, where said main driving motor drives rotation of said first spindle and said auxiliary driving motor does not drive rotation of said second spindle, and in a second mode, where said auxiliary driving motor cooperates with said main driving motor to drive rotation of said first and second spindles so as to deliver a torque which is larger than that delivered in the first mode to the fixture to drive rotation of the fixture.
A rotary table adapted for use in a computer numerical control (CNC) machine that includes a fixture, said rotary table comprising:
- a mounting seat defining a space;
- a spindle disposed in said space, rotatable about an axis, and adapted to be securely connected to an end of the fixture;
- and
- a motor unit including a main driving motor that is directly connected to said spindle so as to directly drive rotation of said spindle, and an auxiliary driving motor that is for driving rotation of said spindle,
- said motor unit being operable in a first mode, where said main driving motor drives rotation of said spindle and said auxiliary driving motor does not drive rotation of said spindle, and in a second mode, where said auxiliary driving motor cooperates with said main driving motor to drive rotation of said spindle so as to deliver a torque which is larger than that delivered in the first mode to the fixture to drive rotation of the fixture.
