Described double tapered push rod (1) is connected on actuator cylinder (2) piston rod, double tapered push rod (1) one end is provided with the conical surface of the steep-taper conical surface (11) and the Small Taper conical surface (12) two sections of different taperings, fit with the end conical surface of paw push rod (6) in double tapered push rod (1) the front end steep-taper conical surface (11), paw push rod (6) footpath can be promoted when moving to left outwards move, make three paws held down assembly in (5) compress the inner side edge edge of drum-type workpiece; Meanwhile, double tapered push rod (1) the front end Small Taper conical surface (12) coordinates with self-centering push rod, makes that three self-centering push rods are synchronously outer to be moved, and inside the edge withstanding on drum-type workpiece, completes the Self-centering Action of drum-type workpiece;
After actuator cylinder (2) piston rod is regained, double tapered push rod (1) is and then return, after self-centering push rod after extractor (7) and paw under extractor (8) elastic force effect, self-centering push rod group (4) and paw push rod (6) are regained, hold down assembly (5) regain simultaneously, be in inside drum-type workpiece (9) endoporus.
Compared with prior art, the beneficial effects of the utility model are:
(1) self-locking device is arranged on jacking hydraulic cylinder rear end, extends the installing space of self-locking device;
(2) structure is simple, and adopt inclined-plane locking, coupling mechanism force is large;
(3) Self-centering Action of drum-type workpiece is achieved.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
With reference to shown in Fig. 1, a kind of double acting double tapered of the utility model push rod is made its central band Song Zhao mechanism by oneself and is made up of extractor (8) after extractor (7), paw after double tapered push rod (1), the steep-taper conical surface (11), the Small Taper conical surface (12), actuator cylinder (2), clamp body (3), self-centering push rod group (4), hold down assembly (5), paw push rod (6), self-centering push rod.
With reference to shown in Fig. 1, when actuator cylinder (2) promotes double tapered push rod (1) reach, under the steep-taper conical surface (11) extruding, radial overhanging with three paw push rods (6) that the steep-taper conical surface (11) is closely connected, after the paw that compression is respective, three paws of extractor (8) pusher dynamic hold down assembly (5) compress the upper edge of the inner ring of drum-type workpiece (9), make (5) compression drum-type workpiece (9) that holds down assembly; Simultaneously, three push rods of the self-centering push rod group (4) closely connected with the Small Taper conical surface (12) are also radial overhanging under the impact of the Small Taper conical surface (12) movement, extractor (7) after compression self-centering push rod, withstand on compress drum-type workpiece (9) endoporus around, play compressing the self-align effect of drum-type workpiece (9) endoporus, now drum-type workpiece (9) is in compacted state.
With reference to shown in Fig. 2, when actuator cylinder (2) drives double tapered push rod (1) to regain, the three piece paw push rods (6) closely connected with the steep-taper conical surface (11) are regained under extractor (8) elastic force effect after respective paw, also make three paws leave the upper edge of the inner ring of drum-type workpiece (9), unclamp workpiece; Simultaneously, under the elastic force effect of three push rods extractor (7) after self-centering push rod of the self-centering push rod group (4) closely connected with the Small Taper conical surface (12), leave and compress drum-type workpiece (9) endoporus, now drum-type workpiece (9) can freely be removed.
