Description
Technical field
The utility model relates to a kind of rotating table of numerical control machine and to stop tight device, belongs to Digit Control Machine Tool brake field.
Background technology
Rotary table is one of critical piece in Digit Control Machine Tool, current rotary table majority adopts worm and gear drive unit to drive, because worm and gear has auto-lock function, therefore its rotary table driven is without the need to brake gear, adopt servomotor to drive clearance elimination gear case and be arranged on the gear ring engagement on workbench, realize the revolution of workbench, but, during motor stalling, because the inertia of gear ring and motor, drive workbench is rotated further, and one is bring potential safety hazard, easily causes operator injured; Two is that free-wheel reduces machine finish, adds process operation difficulty.
Utility model content
The purpose of this utility model is to provide a kind of rotating table of numerical control machine and stops tight device, and structure is simple, stops tightly effective, safe and reliable, improves machine finish.
Rotating table of numerical control machine described in the utility model is stopped tight device, comprise workbench, workbench bottom is provided with hold-down ring, hold-down ring bottom is provided with top board, also comprise the lower platen being positioned at top board bottom, lower platen bottom is provided with lower platen thrust unit, and lower platen thrust unit is fixed on slide, and top board coordinates with lower platen.
Slide is fixed, and workbench is rotatable, and when stopping tight, it is up that lower platen thrust unit promotes lower platen, together with top board fits tightly with lower platen, realizes workbench and stop tightly, guarantee that numerically controlled machine stops operating in time.
Described lower platen thrust unit comprises hydraulic cylinder, is provided with piston rod and disc spring in hydraulic cylinder, and on the piston rod, piston rod outer end is provided with retaining ring to disc spring suit, and retaining ring is positioned at top board top; Be provided with cylinder cap bottom hydraulic cylinder, cylinder cap is provided with inlet; Hydraulic oil is by inlet injection liquid cylinder pressure, promote piston rod moves, piston rod compression disc spring, promote retaining ring is moved simultaneously, retaining ring leaves top board, top board leaves certain interval with lower platen thereupon, workbench throw off described in rotating table of numerical control machine to stop tight device, workbench freely rotates as required; When needing to stop tight, siphon away hydraulic oil by inlet, piston rod moves down under the effect of disc spring pressure, and retaining ring compresses top board, and top board compresses lower platen, and tight workbench of stopping, workbench stops operating.
Described retaining ring bottom is provided with spacer, and spacer suit on the piston rod; The not direct contact piston bar of retaining ring, protection retaining ring and piston rod wearing and tearing, meanwhile, retaining ring compresses lower platen and compresses better effects if.
Pad is provided with between described top board and lower platen; Described pad is copper backing; Compress better effects if.
Described pad connects lower platen; Pad is separated with top board, and top board rotates with workbench.
Described top board side is bolted hold-down ring; Top board compresses better effects if.
Can centrally be evenly arranged multiple described rotating table of numerical control machine along work to stop tight device, tight better effects if of stopping, generally arrange more than 3, effect is better, when stopping tight more firm evenly, more steady when workbench stops.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model structure is simple, by arranging top board and lower platen and pad, compresses effective, tight workbench of can stopping rapidly at short notice, safe and reliable;
(2) by arranging lower platen thrust unit, realizing promoting motion bar by hydraulic cylinder and compressing top board and lower platen, compressing great efforts, compress better reliable, improve machine finish.
(3) simple installation, both can be installed to workbench excircle, also can be installed to inside workbench.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model,
Fig. 2 is the structure for amplifying schematic diagram of A in Fig. 1.
