It is whole.
Background technique
In the design and production of large scale structure numeric terminal equipment, since target is large scale structure, specification
Size range is also larger, needs for multiple drive mechanisms to be displaced to adapt to the size range of large scale structure.Wherein more transmissions
Structure is also required to carry out small-scale relative movement at work and requires mobile accuracy high, if this multiple transmission mechanism point
High precision movement track or lower, the at high cost problem of high precision movement track all efficiency She Zhi not be shared.
Summary of the invention
In order to solve the problems, such as double-deck mobile mechanism's precision adjustment, the utility model provides adjustable double transmissions
Double-deck mobile mechanism's device.The device by the way that mobile mechanism, lower layer and upper layer mobile mechanism are respectively set above and below body structure,
Two kinds of actuation types of rack-and-pinion and ball-screw are wherein respectively adopted, and the precision of linear motion is independently adjusted, solve
The technical issues of mobile mechanism's precision adjusts.
The utility model solves scheme used by technical problem:
The Liang Zu lower layer sliding block of parallel arrangement is installed as supporting element, lower layer's cunning in the lower plane of the body structure of rectangle
Block passes through lower floor guide rail and is moved along it, and wheel and rack is equipped between two groups of sliding blocks and is fitted, drive case structure is along lower layer
Guide rail linear motion, gear and rack gear constitute rack pinion, and form lower layer's moving machine with lower layer's sliding block and lower floor guide rail
Structure；It is provided with and the positive ball-screw of lower floor guide rail cocurrent and parallel, reversed ball-screw, two sides in the upper plane of body structure
Upper layer linear guide equipped with Parallel Symmetric arrangement, positive ball-screw, reversed ball-screw and upper layer linear guide are assemblied in
Upper railings form rectangular frame structure, and positive ball-screw and reversed ball-screw constitute ball-screw-transmission, and lead with upper layer
Rail forms upper layer mobile mechanism, is drivingly connected component on it, is moved while moving along a straight line with body structure.
The body structure drives upper layer mobile mechanism to move integrally along mobile mechanism, lower layer.
Mobile mechanism, the lower layer middle gear rack-driving is divided into fast reconciliation coarse adjustment structure, and lead screw passes in the mobile mechanism of upper layer
It is dynamic to be divided into slow reconciliation adjustment structure, the speed to move along a straight line when adjusting separately mobile.
Good effect, since the utility model is using the double-deck mobile knot of two kinds of mobile mechanism, lower layer and upper layer mobile mechanism
Structure, mobile mechanism, lower layer middle gear rack-driving is as fast reconciliation coarse adjustment；Ball-screw-transmission is as slow in the mobile mechanism of upper layer
Reconciliation accurate adjustment solves linear movement over long distances and high-precision long range track is respectively set or shares a high-precision long range rail
Inefficiency caused by road, problem at high cost；Realize double transmission mechanism long-distance displacements and relative distance small range high-precision
It is adjustable, it reduces costs, improves efficiency.It is suitable for being used as adjustable double double-deck mobile mechanism's devices being driven.
