Famous cake is to being difficult to determine.
However, observing using three-dimensional laser scanner deposit, the three of bulk deposition object surface can be rapidly obtained
Coordinate is tieed up, measurement point is evenly distributed on deposit surface, therefore can quickly and accurately calculate volume.But domestic large size three at present
Dimension laser scanning cubing generallys use artificial or electric drive laser and completes to measure in track sliding, exists
Following problems:
1. can not need to realize that large torque Ultra-Low Speed (1~5 point turns 1 circle) steady high-precision is driven；
2. quick start or parking can bring shake；
3. unstable due to being driven, point cloud will appear random distortion, thus cause the data obtained inaccurate, and error is very
Greatly.
Utility model content

It is fixed on or is removably mounted on pedestal.One end of the fixing axle is fixed on external component, for installing fixed be somebody's turn to do
Device, the other end are mounted on the base by bearing.The laser module installation is on the shell.
The drive mechanism includes mainboard drive controller, stepper motor, endless screw support, shaft coupling, worm and gear.Worm screw
It is mounted on endless screw support, endless screw support is fixedly connected with pedestal.The stepper motor drives worm screw rotation by shaft coupling, then
It drives worm screw to rotate around worm gear by worm screw rotation, drives endless screw support, pedestal, shell to rotate around worm gear by worm screw,
Thus laser module rotation is driven.Worm gear is screwed in the fixing axle by internal screw thread and is fixed by stop nut, and simultaneously
It is engaged with worm screw.
Further, the screw thread that the worm gear is engaged with worm screw is twill.
Further, the shaft coupling is immunity shaft coupling.
Compared with prior art, the utility model has the following beneficial effects:
1. having large torque Ultra-Low Speed (1~5 point turns 1 circle) steady high-precision to be driven；
2. solving the problems, such as that quick start or parking can bring shake in the flat-pushing laser measurement of rail mounted；
3. being continuously worm tooth when it is with worm gear tooth engagement since worm tooth is continuous continual helical tooth
The process of engagement, therefore stable working are not entered into and exit, impact, vibration, noise are small, solve and are driven unstable, point cloud
It will appear random distortion problem；
4. installation is simple, measurement cost is significantly reduced, is saved the time, it is easy to use, and have a wide range of application, not only
In harbour cubing, in engineering detecting, deformation monitoring, historical relic's protection, forest and agricultural, medical research, the neck such as battlefield emulation
