Description
Technical field
The utility model relates to machine tool field, particularly a kind of detection control apparatus of central driving synchronization.
Background technology
China is a lathe demand big country, all needs every year from a large amount of lathes of external import, particularly large-scale, heavy machine tool.The vertical lathe of each lathe manufacturer production is in the control of crossbeam lifting both at home and abroad at present, and roughly can be divided into following several: the crossbeam two ends adopt motor to control respectively, and this mode is difficult to realize driven in synchronism, is easy to crossbeam is caused damage; The lifting action of crossbeam is to be rotated by alternating current generator; after slowing down, drive crossbeam and finish lifting action by two crossbeam elevating screws; this mode is easy to realize; but equally also there is defective: though the crossbeam place is provided with fuse; protections such as electrothermal relay overload; but when crossbeam occur at lifting process mechanical when asynchronous: end rotation appears in crossbeam left and right sides leading screw; one end stops; leading screw asynchronous rotation in the left and right sides will cause the crossbeam motor overload; can cause the crossbeam fracture when serious; cause serious economy loss for plant equipment and factory, even cause personal injury.
In the structure of existing crossbeam central driving synchronization; though crossbeam is provided with protections such as fuse, electrothermal relay overload; but when crossbeam occur at lifting process mechanical when asynchronous: end rotation appears in crossbeam left and right sides leading screw; one end stops; leading screw asynchronous rotation in the left and right sides will cause the crossbeam motor overload; can cause the crossbeam fracture when serious, cause serious economy loss for plant equipment and factory, even cause personal injury.Even above-mentioned situation does not take place, because the asynchronous transmission of left and right sides screw mandrel also can cause the inclination of crossbeam, thereby be delivered to the point of a knife place, cause the decline of machine finish, reduce the quality of processing work.
Summary of the invention
The purpose of this utility model is to provide a kind of detection control apparatus of central driving synchronization, solve to concentrate in the Synchronous Transmission structure because machinery is asynchronous: promptly end rotation appears in crossbeam left and right sides leading screw, one end stops, and plant equipment and factory are caused serious economy loss, even cause personal injury, thereby improve the mechanical synchronization of left and right sides screw mandrel in running, reduce the risk of breakage of part, improve the performance quality of machine tool product.Simultaneously, can guarantee that also the lathe point of a knife is not offset in process, guarantee the machining accuracy of workpiece, reduce manufacturing cost.
For achieving the above object, the technical solution of the utility model is:
A kind of detection control apparatus of central driving synchronization is installed in the left and right elevator chamber of control lathe crossbeam lifting, and left and right elevator chamber connects lifting motor by left and right power transmission shaft respectively; It is characterized in that, comprise that two fluted discs are coaxially installed on the worm gear drive axle top in the left and right elevator chamber; Two are arranged at respectively in the left and right elevator chamber near switch, near the outer rim of the corresponding fluted disc in switch outer end; Two Programmable Logic Controller PLC that are electrically connected to the control lifting motor near switch respectively.
Further, describedly be installed in the left and right elevator chamber by a fixed support near switch.
So-called central driving, promptly motor drives two axles after by decelerator and rotates synchronously, drives the screw mandrel transmission through left and right sides elevator chamber again, and machine tool component is moved up and down.In order to guarantee that left and right sides screw mandrel rotates synchronously, the utility model drives the screw mandrel transmission respectively in the elevator chamber of the left and right sides worm gear drive axle upper end has increased a speed detector, to guarantee that screw mandrel rotates synchronously, guarantee machine tool component not run-off the straight in lifting process, guarantee that the lathe point of a knife is not offset in process, guarantee the machining accuracy of workpiece, reduce manufacturing cost.
After motor (band decelerator) starts; directly driving power transmission shaft rotates; power transmission shaft is connected to a left side respectively; right elevator chamber; and then drive left; right elevator chamber work; through a left side; drive the worm gear drive axle after the right elevator chamber transmission and begin rotation; and then the fluted disc that drive is installed on the worm gear drive axle rotates; when fluted disc rotates; just can respond to a left side near switch; the rotating speed of screw mandrel in the right elevator chamber; with a left side; induced signal near switch in the right elevator chamber inserts PLC; judge a left side that receives by the PLC program; whether the induced signal near switch in the right elevator chamber is consistent; thereby judge the whether synchronously rotation of left and right sides leading screw; near switch fault, the PLC program is just sent alarm signal and is braked lifting motor immediately as the asynchronous rotation of left and right sides leading screw or both sides, and cuts off the purpose that the lifting circuit plays the protection crossbeam.
Advantage of the present utility model is:
The utility model is by increasing a simple mechanical mechanism and one near switch, just can detect very easily whether the worm gear drive axle rotates synchronously in the left and right elevator chamber, and then judge whether left and right sides screw mandrel rotates synchronously, can fundamentally solve the skew that the lathe point of a knife causes owing to above-mentioned situation, improve the precision of machine tooling workpiece.Frame for movement is simple, compact conformation, stable and reliable working performance, low cost of manufacture, can improve the precision of machine tooling workpiece, reduces manufacturing cost.
