A kind of numerical control cutting machine drives guiding mechanism
Technical field
What the present invention relates to is a kind of driving guiding mechanism for numerical control cutting machine.
Background technology
In the prior art, known technology is the driving guiding mechanism support of the numerical control cutting machine used now is cantilever design, the bottom of support is provided with rack and pinion and realizes moving ahead of cantilever mechanism or retreat, in use, support easily deforms, cause rack and pinion engagement bad, and then the rack-and-pinion life-span is declined, and in support high-speed cruising or heavy load constantly, support easily trembles also can produce gap, cause running stability poor, machine tool accuracy reduces, and this is the weak point existing for prior art.
Summary of the invention
Object of the present invention is exactly for the deficiency existing for prior art, and provide a kind of numerical control cutting machine to drive the technical scheme of guiding mechanism, the driving guiding mechanism of the program effectively can eliminate the stuck and chattering of support, ensure cutting accuracy and cut quality, elasticity and the compensate for wear of the engagement of rack and pinion can also be adjusted automatically, promote the service life of gear and tooth bar, and light structure, be convenient to installation and maintenance.
This programme is achieved by the following technical measures: a kind of numerical control cutting machine drives guiding mechanism, comprise connecting plate, the feature of this programme is: described connecting plate is provided with the supporting plate for fixed drive mechanism, one end of described supporting plate is connected with connecting plate by connecting axle, supporting plate can rotate around connecting axle, at described supporting plate, one end of connecting axle is provided with adjustable plate, described adjustable plate is fixed by pretension adjusting screw(rod) and connecting plate, described pretension adjusting screw(rod) is provided with spring, at described connecting plate, one end of connecting axle is provided with the limiting plate preventing supporting plate from shaking, limiting plate is fixed for the adjustment cam clamping supporting plate.The top of described connecting axle is provided with dust cover.Taper roll bearing is provided with between described connecting axle and connecting plate.Described pretension adjusting screw(rod) is provided with the spring support for fixing spring, the end thereof contacts spring support of spring, the other end contact adjustable plate of spring.Described connecting plate is provided with multiple fixing hole, and driving mechanism is servomotor.
The beneficial effect of this programme can be learnt according to describing of such scheme, and due to driving mechanism in this scenario, driving mechanism driven wheel runs along tooth bar, drives whole driving guiding mechanism move, and then drives the operation of support, cantilever design; The supporting plate of fixed drive mechanism is connected with connecting plate by connecting axle, and supporting plate can rotate along connecting axle; Be provided with taper roll bearing between described connecting axle and connecting plate, larger radial load and axial load can be born; The top of connecting axle is provided with dust cover, can be effectively dust-proof, ensures the service life of taper roll bearing; Connecting plate is provided with the limiting plate preventing supporting plate from shaking, and limiting plate is fixed for the adjustment cam clamping supporting plate, can avoids occurring trembling during high-speed cruising, elevator bed ensemble traveling comfort, and then ensures cutting accuracy and the cut quality of lathe; Adjustable plate is fixed by pretension adjusting screw(rod) and connecting plate, described pretension adjusting screw(rod) is provided with spring, in running, when run into tooth bar injustice local time, under the action of the spring, effectively by gear and tooth bar engagement, stuck phenomenon can be prevented, and extends the service life of rack and pinion; Connecting plate is provided with multiple fixing hole, support or cantilever can be used for fixing.
As can be seen here, compared with prior art, have outstanding substantive distinguishing features and significant progress, its beneficial effect implemented also is apparent in the present invention.
