When platform is moved to arc trajectory, the sliding block on workbench deviates from separation from line slideway, and workbench enters camber line rail
In mark, so, line slideway would not cause to interfere to movement of the workbench on arc trajectory, under the drive of transmission belt
Movement of the workbench on arc trajectory is can be achieved with, when workbench is again moved on straight path by arc trajectory
When, the sliding block on workbench can be inserted on line slideway again, be engaged with line slideway, realized the shifting on straight path
It is dynamic, so alternately and repeatedly, it is achieved thereby that the transmission track of ring-shaped guide rail.Therefore, the present invention can cause work by above-mentioned design
Part quickly moves between station, move stopping after, workpiece has good positional precision and the letter of the structure of the ring-shaped guide rail
It is single, it is low to reduce manufacturing cost.A dustproof space is formed using transmission belt, upper and lower dust cover so that sliding block and line slideway
It is entirely located in this dustproof space, so as to serve dustproof effect, further increases the transmission accuracy of the present embodiment.By right
The design of contiguous block and transmission belt, positional precision during workbench transmission can be further ensured that.By setting double-deck straight line to lead
Rail structure, the loading capacity of workbench can be improved.
" multiple " described in the present embodiment refer to the quantity of " two or more ".Above example is only for illustrating this
Invention is used, rather than limitation of the present invention, and person skilled in the relevant technique is not departing from the spirit and scope of the present invention
In the case of, it can also make a variety of changes or convert, therefore all equivalent technical schemes should also belong to the guarantor of the present invention
Scope is protected, protection scope of the present invention should be limited by each claim.
