Description
Technical field
The utility model relates to a kind of double-workbench lathe, particularly a kind of worktable rotary exchange mechanism.
Background technology
The double-workbench lathe often need to carry out the workbench exchange at work, and the workbench exchange is completed by the rotation exchange mechanism.Traditional rotation exchange mechanism comprises the board that is fixed on the exchange pedestal, the board middle part is equipped with the exchange casing, be equipped with to lift in the exchange casing and fall oil cylinder, lift the cylinder body top that falls oil cylinder and be fixed with supporting mechanism, the supporting mechanism both sides are respectively equipped with workbench, two work tops are respectively equipped with the workbench drag hook to a side of supporting mechanism, and the two ends of supporting mechanism are arranged with the picking-up drag hook that workbench can be lifted; The workbench drag hook respectively with corresponding picking-up drag hook tabling, the bottom of two workbench is supported on board by rotary disk respectively.Traditional rotation exchange mechanism also is provided with gantry assembly and axis, and there is larger die cavity the crossbeam inside of upper end, gantry, and the rotary oil cylinder assembly is put in the assembly of gantry.Before the workbench exchange, lift and fall oil cylinder and first axis is lifted, axis drives two workbench and together lifts, the tooth bar that lifts on the rear rotary oil cylinder that puts in place moves the drive middle shaft rotation, thereby drive two worktable rotaries, lift after being rotated in place and fall oil cylinder and unclamp axis, four location bowls and four alignment pins above positioning disk below workbench are located automatically by the conical surface, thereby realize whole switching motion.
Traditional structure has the following disadvantages: axis is in assembling process, and the lifting of upper end, gantry falls axis that oil cylinder is connected with the exchange pedestal, and to be difficult to assurance concentric, thereby bring frictional resistance to rotation; Two workbench centers of gravity of rotary oil cylinder distance are far away, and during rotation, the torsion of axis can make table positions inaccurate, and what at this moment axis must be done more just can overcome torsion; When another did not have when on one of them workbench, part being arranged, axis will bear very large disturbing moment, is easy to bending.Three kinds of different power all act on axis, are very harsh to the matching requirements of axis, and when any situation wherein occurs, a whole set of exchange mechanism just can't use.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of worktable rotary exchange mechanism of simple in structure, reliable operation is provided.
For solving above technical problem, a kind of worktable rotary exchange mechanism of the present utility model, comprise the board that is fixed on the exchange pedestal, described board middle part is equipped with the exchange casing, be equipped with to lift in described exchange casing and fall oil cylinder, the described cylinder body top that falls oil cylinder of lifting is fixed with supporting mechanism, described supporting mechanism both sides are respectively equipped with workbench, two described work tops are respectively equipped with the workbench drag hook to a side of described supporting mechanism, and the two ends of described supporting mechanism are arranged with the picking-up drag hook that workbench can be lifted; Described workbench drag hook respectively with corresponding picking-up drag hook tabling, the bottom of two workbench is supported on described board by rotary disk respectively, in described exchange casing, the rotary drive mechanism that axis is the level of state is installed also, the middle part of described rotary drive mechanism is tooth bar, and the two ends of described rotary drive mechanism are respectively equipped with and drive the rack drives oil cylinder that tooth bar axially moves; The described cylinder body periphery that falls oil cylinder of lifting is set with the spline tooth wheel case, and the internal spline of described spline tooth wheel case is meshed with the described external splines that falls oil cylinder that lifts, and the gear of described spline tooth wheel case is meshed with described tooth bar.
With respect to prior art, the utility model has been obtained following beneficial effect: during pallet changer, lift and fall oil cylinder with the supporting mechanism jack-up that makes progress, the picking-up drag hook of supporting mechanism tangles the workbench drag hook two workbench is synchronously risen, then rack drives hydraulic oil cylinder driving tooth bar axially moves, the rotation of rack drives spline tooth wheel case, the spline gear cover drives to lift and falls oil cylinder, supporting mechanism and the rotation of two workbench, after two workbench exchanges put in place, lift and fall oil cylinder and fall, workbench is thereupon lower falls behind locking.The utility model has been cancelled traditional axis, has reduced cost, and rotary driving force can overcome more near the center of gravity of two workbench the moment of torsion that friction brings better.
As improvement of the present utility model, on described exchange casing, supplemental support is installed, the front end of described supplemental support withstands on the back side of described tooth bar, and is corresponding with the position of described spline tooth wheel case engagement, and the rear end of described supplemental support is fixed by screws on described exchange casing.Tooth bar can be subject to very large reaction force when driving the spline tooth wheel case and rotate, at the back side at tooth bar engagement position, supplemental support is set and can makes the deflection of tooth bar less.
