The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described: a kind of numerical control hydraulic equal-division rotary table, comprise a body 1, workbench 6, on bed body 1, by angular contact ball bearing 7, be provided with main shaft 8, main shaft 8 one end are fixedly equipped with gear 9, the other end is fixedly linked with screw and workbench 6, gear 9 is meshed with tooth bar 14, tooth bar 14 is arranged in oil cylinder A, tooth bar 14 two ends fixed installation piston A22, piston B15, piston A22 and piston B15 are respectively equipped with to slow down and insert pin A12, slow down and insert pin B16, slow down and insert pin A12 and oil cylinder A13 end hole, slowing down, it is corresponding with oil cylinder B17 end hole to insert pin B16, between workbench 6 and bed body 1, be equipped with unilateral thrust cylinder roller bearing 5, axially loaded bearing is unilateral thrust cylinder roller bearing 5, its format diameter is equivalent to 2/3rds of mesa diameter, while bearing heavy duty like this, stressed diameter is relatively large, just can not produce lever principle, rotation steadily, even if there is unbalance loading also can not exert an influence to product, on workbench 6, be fixed with positioning sleeve 4, on positioning sleeve 4, establish locating slot, bed body 1 is provided with and unclamps latching ram 3, the front end that unclamps latching ram 3 is corresponding with the locating slot on positioning sleeve 4, the rear end of unclamping latching ram 3 is provided with piston cap 2, bed body 1 is provided with the tense-lax exploitation letter sensor 20 of stopping being connected with system control cabinet, the promotion sensor 21 of posting a letter that puts in place, bed body 1, main shaft 8 is provided with pre-load nut 17, the oil cylinder A13 end at two ends is provided with blind flange A11, oil cylinder B17 end is provided with blind flange B18, blind flange A11 is provided with deceleration adjusting pin A10, on blind flange B18, establish deceleration adjusting pin B19, two deceleration adjusting pins can regulate throttling size, control buffer speed, radial force bearing has adopted pair of horns contact ball bearing 7, the precision corner contact ball bearing 7 using is in pairs through after pretension, radial force positioning precision improves greatly, and rotation pre-load nut 23 can be adjusted the pretightning force of angular contact ball bearing 7, control idling torque, while rotating due to turntable, there is inertia, therefore rotation must be slowed down when position, otherwise can produce to impact and reduce life of product, when promoting in the other direction, slow down and insert pin A12, slow down and insert the hydraulic oil of pin B16 meeting closure reflux, form instantaneous deboost, thereby reach the object of buffering.
