Abstract
An adjusting mechanism is disclosed. The adjusting mechanism has a differential, first and second stepping motors engaging with the differential, a screw rod connected to the output shaft of the differential such that the screw rod rotates along with the rotation of the output shaft, and a moving block threadably connected to the screw rod to permit motion of the moving block along the longitudinal axis of the screw rod. The output shaft of the adjusting mechanism rotates according to the rotation of the first and second stepping motors, so as to drive the movement of the moving block along the screw rod.
Claims20
An adjusting mechanism, comprising:
- a differential including a first output shaft, a second output shaft, a first driven gear, and a second driven gear, the second output shaft connected to the first driven gear and the second driven gear;
- a first stepping motor with a first drive gear disposed on a rotary shaft thereof, the first drive gear engaging with the first driven gear;
- a second stepping motor with a second drive gear disposed on a rotary shaft thereof, the second drive gear engaging with the second driven gear;
- a screw rod connected to the first output shaft at a first end of the screw rod such that the screw rod rotates along with a rotation of the first output shaft;
- and
- a moving block threadably connected to the screw rod to permit motion of the moving block along a longitudinal axis of the screw rod;
- wherein
- the first output shaft rotates according to a rotation of the first and second stepping motors so as to drive a movement of the moving block along the screw rod.
A laser collimator, comprising:
- a swinging bracket;
- a laser connected to the swinging bracket;
- a level sensor connected to the laser;
- and
- an adjusting mechanism including
- a differential including a first output shaft, a second output shaft, a first driven gear, and a second driven gear, the second output shaft connected to the first driven gear and the second driven gear, a first stepping motor with a first drive gear disposed on a rotary shaft thereof, the first drive gear engaging with the first driven gear,
- a second stepping motor with a second drive gear disposed on a rotary shaft thereof, the second drive gear engaging with the second driven gear,
- a screw rod connected to the first output shaft at a first end of the screw rod such that the screw rod rotates along with the rotation of the first output shaft, and
- a moving block threadably connected to the screw rod to permit motion of the moving block along the longitudinal axis of the screw rod, wherein the first output shaft rotates with the rotation of the first and second stepping motors so as to drive the movement of the moving block along the screw rod;
- wherein
- the swinging bracket is connected with the moving block.
