Fig. 2 is rotating main body structure of the present invention, sequence number explanation in figure: driven end base anchor 101, drive end base anchor 102, driven end base 103, drive end base 104, hexahedron steel structure 105, drive end main shaft 106, planet-gear speed reducer 107, servomotor 108, driven end main shaft 109, bearing block 110, back track 111, cantilever 112, approach switch support 113, frictional disk 114, air disc brake 115, swivel joint 116, Timing Belt 117, encoder 118.
Described rotating main body structure is set to: driven end base 103 and drive end base 104, drop on respectively on driven end base anchor 101 and drive end base anchor 102, and by adjustment screw adjustable height, thereby make two base upper surfaces parallel to the ground; Drive end main shaft 106 and driven end main shaft 109 are fixed by screws in two end faces of hexahedron steel structure 105, and wherein driven end main shaft is hollow-core construction; Drive end main shaft 106 is direct-connected with planet-gear speed reducer 107 outputs, and servomotor 108 is direct-connected with planet-gear speed reducer 107 inputs, and planet-gear speed reducer 107 is fixed on drive end base 104; Driven end main shaft 109 is by bearings on bearing block 110, and bearing block 110 is fixed on driven end base 103; Planet-gear speed reducer 107 and bearing block 110 all can, by pad adjustment height, be adjusted horizontal level by adjustment screw; Driven end base 103, drive end base 104 be adjusted into coarse adjustment, planet-gear speed reducer 107, bearing block 110 be adjusted into accurate adjustment, the depth of parallelism of the whole final assurance hexahedron rotation of two steps and ground and vehicle body throughput direction.
Described back track 111 is screwed on hexahedron steel structure 105, for support fixture back, by adjusting the roller set at fixture back, the support force of adjustable back track to fixture, when this support force becomes large, fixture will reduce the rail pressure being installed on cantilever 112, thereby the distortion of track is reduced; Described cantilever 112 is screwed on 105 4 working faces of hexahedron steel structure, 3 of each working faces, and common support fixture track, connects into whole to increase rigidity with screw between the cantilever of Adjacent Working Face; Approach switch support 113 is fixed on the connecting cross beam between cantilever 112, and the approach switch being installed on it can carry out identification to the fixture of relevant work face, thereby guarantees to provide corresponding with it fixture for different vehicles.
Described frictional disk 114 is screwed on driven end main shaft 109, and frictional disk is two semicircle docks, easy disassembly; Air disc brake 115 is distributed on frictional disk circumference, is spring braking, the normally closed structure of pneumatic release; When rotating main body 1 is static, brake is locking state, and during rotating main body 1 rotation, brake ventilation is opened.In rotating main body 1 rotary course, unbalance loading moment of torsion and the moment of inertia of system and the output torque balance of drive end that fixture produces, when rotating main body 1 stops the rotation, it is constant that the output torque of drive end keeps, when now fixture moves into or shifts out rotating main body 1, the unbalance loading moment of torsion of system changes, at bolt mechanism from rotating main body 1 is extracted, the moment of torsion of system is by disequilibrium, existence due to planet-gear speed reducer 107 gear back clearances, rotating main body 1 is by the process that has to sink or upwarp, and the adding of air disc brake 115, just for fear of the generation of this phenomenon: brake clamps moment of torsion that frictional disk produces moved into or shifted out rotating main body 1 generation difference in torque with fixture and equates, after bolt mechanism is extracted, brake coordinates the startup of servomotor, ventilation is decontroled gradually, thereby make rotating main body 1 start stably rotation.
Described Timing Belt 116, large synchronizing wheel is fixed on driven end main shaft 109 end faces, little synchronizing wheel endoporus is worn a concentric shafts, this axle is by two bearings, through bearing block, be fixed on driven end base 103, the other end of axle connects with absolute value encoder 117 through shaft coupling, and under the effect of Timing Belt, the rotating speed of the rotating speed of encoder 117 and rotating main body 1 is consistent.Encoder 117 can feed back hexahedral rotating speed in time, forms two closed loop servo-control systems with servomotor 108 internal encoders, can accurately control rotating main body 1 anglec of rotation.
Described swivel joint 118, be fixed on large synchronizing wheel end face, communication signal and compressed air can be delivered to the fixture place on rotating main body 1 working face through the hollow core of driven end main shaft 109, thereby make hexahedron rotation not limited by drag chain, can not limit the random rotating of the number of turns, reduce and remodel time, for random switching in multi-vehicle-type beat provides safeguard.
