Adjusting mechanism and laser collimator with same

Abstract

The invention provides an adjusting mechanism and a laser collimator. The adjusting mechanism comprises a differential gear, a first stepping motor, a second stepping motor, a screw rod and a movable block, wherein the differential gear comprises a first output shaft, a second output shaft and a first driven gear; a second driven gear is arranged at the end, extending out of the differential gear, of the second output shaft; a first driving gear is arranged at the rotating shaft of the first stepping motor, and is meshed with the first driven gear; a second driving gear is arranged at the rotating shaft of the second stepping motor, and is meshed with the second driven gear; the first end of the screw rod is connected with the first output shaft, and the screw rod rotates along with the rotation of the first output shaft; the movable block is in threaded connection with the screw rod, and moves in the axial direction of the screw rod along with the rotation of the screw rod; the first output shaft rotates when the first stepping motor and the second stepping motor rotate in the same direction, in different directions or independently, thereby driving the movable block to move.

Description

technical field [0001] The first aspect of the present invention relates to an adjustment mechanism, in particular to a leveling mechanism for a laser alignment instrument. [0002] The second aspect of the present invention relates to a laser alignment instrument comprising the above adjustment mechanism. Background technique [0003] In the laser alignment instrument, the laser emitter is generally arranged on a suspension device or a swing support, and an adjustment mechanism is used to level the suspension device or swing support, so that the laser emitter is at a level. [0004] Taking the swing bracket as an example, in the prior art, the adjustment mechanism usually uses a single motor to level the adjustment mechanism, but in the case of using one motor, due to the inherent characteristics of the motor, the subdivision of the transmission part in the adjustment structure Accuracy and speed are difficult to balance at the same time. [0005] Therefore, there is an u...
