Description
Technical field
A kind of corner micro-adjusting mechanism is the utility model is related to, refers in particular to a kind of 3 Shaft angle micro-adjusting mechanisms.
Background technology
The attitude information of Rigid Body In Space includes the corner information around 3 axles, to realize in Rigid Body In Space attitude information
The high-acruracy survey of any component, at the beginning of measurement, it don't fail to ensure that obliquity sensor etc. is used for measurement space rigid body appearance
There is consistent posture relation between the measuring instrument of state information, with rigid body to be measured.However, complete measuring instrument relative to
After the coarse adjustment of the installation site of rigid body to be measured, want to only rely upon the experience of worker, make measuring instrument and rigid body to be measured
Between have identical posture relation be extremely difficult.Therefore, the installation carrier using corner micro-adjusting mechanism as measuring instrument,
It is further the optimal path for solving the problem by means of the corner fine adjustment function of corner micro-adjusting mechanism.
Traditional corner micro-adjusting mechanism, mainly there are three big drawbacks：First, most of corner micro-adjusting mechanisms, are mostly directed to
The corner of single shaft or two axles is finely tuned, therefore traditional single shaft is also or two Shaft angle micro-adjusting mechanisms, tends not to realize around 3 axles
The adjustment of corner attitude information.Second, most corner micro-adjusting mechanism, all inevasible to have the problem of backlass,
One side backlass can bring the uncertainty of trim process, on the other hand then reduce the rigidity of structure, destroy and adjusted
The stability of journey.Third, most of traditional corner micro-adjusting mechanisms are in the trim process of corner is realized, it is often necessary to pine in advance
Open locking device, the adjustment around each Shaft angle secondly could be carried out, is finally locked again after the fine setting of corner is realized.
But can not ignore, because locking process is a process to exert a force again, the process very likely makes micro-adjusting mechanism again
It is secondary to shift, and then cause its original posture to be destroyed.
