Description
Technical field
The utility model relates to a kind of machine tool component technical field, particularly relates to a kind of Digit Control Machine Tool oild chuck.
Background technology
Chuck lathe is used for the mechanical device of clamping work pieces.Utilize and be distributed on moving radially of movable jaw on chuck body, the machine tool accessories of Workpiece clamping and location.Chuck is generally made up of chuck body, movable jaw and claw driving mechanism 3 part.Chuck body diameter is minimum is 65 millimeters, maximumly reaches 1500 millimeters, and there are through hole in central authorities, so that by workpiece or bar; There is cylindrical or short taper profile structure at back, directly or be connected by ring flange and machine tool chief axis end.Chuck is usually arranged on lathe, cylindrical grinder and internal grinder and uses, and also can coordinate with various indexing means, for milling machine and drilling machine.
Along with the requirement that people are more and more higher to operating efficiency, oild chuck replaces hand chuck gradually, is widely used.For meeting the processing request of different workpieces, as the workpiece of some irregular shape surfaces such as rectangular surfaces, cylinder black skin, and there is eccentric workpiece in some clamping faces and machined surface, usually needs to adopt four paws oild chuck.Make a general survey of the four paws oild chuck that domestic and international oild chuck manufacturer produces, its structure is a hydraulic oil cylinder driving four jaws and clamps simultaneously, workpiece centre is difficult to coaxial with main shaft rotation center, and the adjustment of each Clamping Center all must by realizing from car jaw, very inconvenient.Even if adjust more accurate, due to the deviation of workpiece self clamping face, according to the principle of three points centering, still can not realize at 4 with circle, in four jaws, after three-jaw clamping, four paws is empty folder.When cutting force is larger, chucking power not, may cause waste product even to have an accident, constrains the application of four paws oild chuck.The four paws self-centering oild chuck that had producer to develop, and be successfully applied on 1.2m numerical control vertical lathe.Highlight the structure of this chuck, operation principle, the adjustment of jaw and the calculating of clamping force herein.The unbalance stress of current existing chuck claw when holding workpiece, causes machining accuracy lower.
Utility model content
It is large that the technical problems to be solved in the utility model is to provide a kind of clamping force, and clamping deviation is little, easy to operate Digit Control Machine Tool oild chuck.
For solving the problem, the utility model adopts following technical scheme:
A kind of Digit Control Machine Tool oild chuck, comprise claw, slide block, workbench, oil cylinder one and oil cylinder two, described claw is fixedly connected with slide block, the setting of oil cylinder one and oil cylinder two can keep claw stable, claw can firmly clamping work pieces by the movement of slide block, described slide block and workbench are slidably connected, lever and horizontal pulling block is provided with in described workbench, lever and horizontal pulling block transmission efficiently can keep larger clamping force, described horizontal pulling block side is provided with locking nut, described horizontal pulling block is fixedly connected with slide block by locking nut, described oil cylinder one is located at above oil cylinder two, described oil cylinder one is fixedly connected with workbench, piston one is provided with in described oil cylinder one, piston two is provided with in described oil cylinder two, described piston one is slidably connected with piston two, described piston two is provided with fairlead, described fairlead is in transmission connection with piston one and piston two respectively.
As preferably, described lever, horizontal pulling block and fairlead are in transmission connection successively, keep the unobstructed of transmission.
As preferably, the diameter of described piston one is greater than the diameter of piston two, and piston rod two can be slided in piston rod one.
As preferably, described piston one is slidably connected with oil cylinder one, can steadily hydraulic drive.
As preferably, described piston two is slidably connected with oil cylinder two, can steadily hydraulic drive.
It is large that this technical scheme has clamping force, and clamping deviation is little, easy to operate feature.
The beneficial effects of the utility model are: the oil cylinder one of setting and the setting of oil cylinder two can keep claw stable, claw can firmly clamping work pieces by the movement of slide block, lever and horizontal pulling block transmission efficiently can keep larger clamping force, the diameter of piston one is greater than the diameter of piston two, and piston rod two can be slided in piston rod one.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
