Description

Annulus fixture
Technical field
The utility model belongs to machinery equipment field, more particularly to a kind of annulus fixture.
Background technology
China is a lathe demand big country, is required for every year from a large amount of lathes of external import, particularly large-scale, heavy machine Bed.In recent years, the demand of complex milling machine tool at home also increasingly increases, and complex milling machine tool is by the function of lathe and milling machine It is fused into one, energy maximum possible meets user to work pieces process efficiency, the requirement of process automation.But lathe and milling machine Operation principle is completely different, and lathe is to use worktable rotary, and the non-rotary mode of cutter realizes processing;Milling machine is to adopt Rotated with cutter, the non-rotary mode of workbench is processed.For complex milling machine tool, there is car function to be converted into milling function When it is necessary to which workbench is switched to fix by rotating, it is therefore desirable to a set of locking device for worktable.
At present, the gripping mechanism of rotary table can substantially be divided into following several:One kind is the peace inside workbench Base-mounted clamping device, the clamping device are clamped (inside workbench by the way of inclined-plane clamps gear ring inner circular ring Clamp);Another kind is mounted in the clamping device of chassis outer side, and the clamping device uses arc surface clamping table lower end flange Mode be clamped.Two kinds of clamping modes, the general principle of use is the same, due to the spacing very little between working face, and Clamping face is arc surface, and therefore, installation and debugging are highly difficult, slightly deviation, in the turning course of workbench, gear ring or work platform convex Edge can collide with clamping device, so as to influence the normal work of lathe, reduce production efficiency.In addition, also T-shaped supporting plate is drawn Compact form, steel ball Draw bar lock compact form, T-shaped supporting plate tension-type clamp system using four conical surfaces position support or central supported by the way of, Clamping force and the work top strong point tend not to one heart, make work top produce additional deformation in the presence of clamping force, directly Connecing influences the precision of rotary table table top, and then influences the machining accuracy of lathe.Although steel ball Draw bar lock compact form realizes pair The clamping of workbench, but clamping force is relatively small.While the gripping mechanism generally existing of prior art is cumbersome, labor intensity Greatly, install that inconvenience, maintenance difficult, operating efficiency be low, poor reliability, can only position in the horizontal direction.
In order to solve the above-mentioned technical problem, people have carried out long-term exploration, such as Chinese patent discloses a kind of revolution Tischarretierungsvorrichtung and its clamping means [application number:CN201110432347.X], including:Clamping body, it has a level The U-shaped breach of direction opening, be respectively arranged with upper and lower two medial surface of the U-shaped breach relatively parallel upper guide plate and Lower guide plate, gear is between upper guide plate and lower guide plate;The upper and lower side of the clamping body is provided with a position restrainer Structure;Oil cylinder, positioned at the underface of clamping body lower end position-limit mechanism, the oil cylinder has the oil pocket of a lower ending opening, described First pipe joint and the second pipe joint are installed, first pipe joint connects the first oil circuit, and second pipe connects on the outside of oil cylinder Head the second oil circuit of connection, first oil circuit and the second oil circuit connect the top and bottom of the oil pocket respectively, in the oil pocket Piston is provided with, the piston isolates first oil circuit and the second oil circuit, and the piston has a bulge loop, the bulge loop closing The lower ending opening of the oil pocket;The oil cylinder lower end is embedded with pressing plate, and the oil cylinder has with the pressing plate in the vertical direction Gap;Piston rod, the clamping body, position-limit mechanism, oil cylinder and the pressing plate are penetrated vertically;The both ends of the piston rod are arranged There is locking nut.
Although such scheme solves partial technical problems, but still have defect, such as structure is excessively complicated, and nothing Method neatly positions etc. to the vertical direction of workpiece.
