Description
Technical field
The invention belongs to mechanical manufacturing field, and in particular to put down the centre that a kind of crown-block type gantry machining center is laterally driven
Weighing apparatus drive device.
Background technology
Crown-block type gantry machining center transverse transmission structure is typically using crossbeam two ends two lines rail as guide rail, line
Trackside installs ball screw arrangement.
As shown in Fig. 1 single track driving structures, when only one side guide rail 1 installs leading screw 2, started by motor 3, and another side
Delayed during in the presence of starting, both sides are asynchronous when causing crossbeam 4 to move, and influence machining center kinematic accuracy.
As shown in Fig. 2 Biaxial synchronous driving structures, drive is there is again when being driven with leading screw 2 using both sides guide rail 1 simultaneously
The problem of the dynamic servo synchronization of motor 3, once the origin of motor 3 occurs deviation, will cause crossbeam 4 that torsion occurs, and serious will cause
The precision of crossbeam 4 is lost.
Therefore, the present invention is the presence of the above-mentioned 2 kinds of problems of solution, there is provided a kind of crown-block type gantry machining center is laterally passed
Dynamic intermediate equilibria drive device.
The content of the invention
Goal of the invention：It is horizontal the invention provides a kind of crown-block type gantry machining center in order to solve the deficiencies in the prior art
To the intermediate equilibria drive device of transmission.
Technical scheme：A kind of intermediate equilibria drive device of the horizontal transmission of crown-block type gantry machining center, including three led
Rail：First guide rail, the second guide rail, the 3rd guide rail, second guide rail are located between the first guide rail and the 3rd guide rail, and described second
Leading screw, the leading screw and motor connection are installed by guide rail, leading screw, first guide rail, the second guide rail, the are driven by motor
Crossbeam is installed, the leading screw drives cross beam movement, and the leading screw driving force effect is led in the first guide rail and the 3rd on three guide rails
Driving moment all same on rail, makes the power in crossbeam motion process on the first guide rail and the 3rd guide rail identical, it is ensured that crossbeam
Two end motion synchronizations.
As optimization：It is arranged in parallel that first guide rail, the second guide rail and the 3rd guide rail are located at same level.
Beneficial effect：A kind of balance driving structure of present invention exploitation, is oriented to and load-bearing, by intermediate rail using three guide rails
Leading screw is installed and drives whole crossbeam, driving moment of the middle leading screw driving force effect on the right and left guide rail is identical, it is ensured that be horizontal
Power in beam motion process on the guide rail of two ends is identical, so as to ensure the end motion synchronization of crossbeam two, it is ensured that crossbeam mass motion is same
Step.
