The specific embodiment
That the utility model is described in further detail is as follows below in conjunction with accompanying drawing:
The utility model comprises oil cylinder 1, in oil cylinder 1, be provided with the piston 2 that has piston packing 5,3 fixedly connected location guide rods 4 on the oil cylinder bonnet, one is provided with spring 21 around location guide 4 on oil cylinder bonnet 3, the both sides that are positioned at piston 2 in oil cylinder 1 are provided with oil inlet and outlet 19, at the fixedly connected piston guide rod 6 of the front end of piston 2, the other end of this location guide 4 with stretch in the piston guide rod 6, the front end outside of this piston guide rod 6 is by the piston guide rod lid 7 that has been threaded, front end at oil cylinder 1 is provided with oil cylinder gland 16, in oil cylinder gland 16, be provided with sealing ring 8 around piston guide rod 6, tapered and be provided with chuck pull bar 9 in the front inner wall of piston guide rod lid 7, cover at chuck pull bar 9 and piston guide rod and to be set with a tapering bearing 10 between 7 inwalls, be provided with a pressure bearing 11 between piston guide rod 6 and chuck pull bar 9, the end of chuck pull bar 9 links to each other with chuck.This chuck comprises chuck seat 12, jig 13, and the inwall of this chuck seat 12 is tapered, and the outer wall of jig 13 is tapered, and the inwall tapering of its tapering and chuck seat 12 matches, and the inwall of jig 13 is cylindrical.The scrap that is produced when solving the turner part also has discharging opening 14 on the sidewall of chuck seat 12; In order to prevent that jig 13 and chuck seat 12 from relative displacement taking place in rotation process, chuck seat 12 is provided with bolt 15, has on the outer wall of jig 13 and the corresponding groove in its position; In order to strengthen the fastness of chuck seat, also be fixedly connected with stiffener 17 at the outer wall of chuck seat 12; For the influence of protecting chuck pull bar 9 and piston guide rod lid 7 not to be subjected to extraneous factor such as dust etc., be bolted to connection protective sleeve 18 at the opposite side of oil cylinder gland 16.In use, workpiece is put into jig 13, to the oiling supercharging of oil cylinder 1 inner carrier 2 right sides, piston 2 is to left movement, piston guide rod 6 pulling piston guide rod lids 7 are also to left movement, so just chuck pull bar 9 is spurred left, jig 13 moves in chuck seat 12, because chuck seat 12 inwalls are taper, just workpiece can be blocked, when workpiece rotates,, therefore overcome the workpiece rotation and must drive the problem that piston 2 rotates together owing in piston guide rod lid 7, be provided with tapering bearing 10, in the time of need loosening workpiece, to the oiling supercharging of piston 2 left sides, piston 2 moves to right, and piston guide rod 6 promotes chuck pull bars 9 and moves right, jig 13 moves to right, can loosen the clamping to workpiece, be provided with a pressure bearing 11 between piston guide rod 6 and chuck pull bar 9, piston guide rod 6 is not influenced by the rotation of chuck pull bar 9 can and rotate thereupon like this.In oil cylinder gland 16, be provided with sealing ring 8, can prevent the oil leakage around piston guide rod 6; Fixedly connected location guide 4 and spring 21 are adjacent to oil cylinder bonnet 3 in case piston 2 moves to left, and can't refuel to piston 3 left sides on oil cylinder bonnet 3.Oil cylinder gland 16 sidewalls are provided with oil spilling mouth 20, can prevent from that oil pressure is excessive to overflow, and the utility model especially is fit to 6120 and 6140 lathes to be used, and compared with prior art, the utlity model has the characteristics of easy to use, laborsaving and high efficiency.
