The specific embodiment
For further understanding technology contents of the present utility model, characteristics and effect, enumerate following example now, and be described with reference to the accompanying drawings as follows:
See also accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5.
Embodiment 1
A kind of hydroelectricity generator rotor magnetic pole iron core press-loading apparatus, chassis 8, piston rod 1, fore-stock 3, after-poppet 6, stretching oil cylinder 2, nut 7 and Hydraulic Power Transmission System are arranged, be provided with the folded in advance frame 5 of pole lamination, the stretching oil cylinder is arranged in pole lamination 4 both sides on support, on Hydraulic Power Transmission System is arranged is hydraulic gear and two mechanical transmission mechanisms that the stretching oil cylinder is synchronized with the movement that two stretching oil cylinders 2 are synchronized with the movement.Hydraulic gear is provided with the oil pressure pressure of two stretching oil cylinders 9 of supply and synchronous distributing valve 10, solenoid directional control valve 11, pressure regulator valve 12, the hydraulic pump 13 of flow, can accurately supply with the oil pressure pressure and the flow of two stretching oil cylinders.With two tight front and back supports of stretching oil cylinder lock piston that movement velocity is identical, stroke hold-down mechanism keeping parallelism motion mode.
The characteristics of the big-and-middle-sized Hydropower Unit rotor magnetic pole iron core of present embodiment press-loading device are:
(1) changing by pole core pole body center arrangement oil cylinder piston be structure at pole core both sides layout stretching oil cylinder, has created to compress, measure, adjust the condition that penetrates stretching screw behind the pole core.
(2) this structure adopts two Hydraulic Power Transmission Systems that the stretching oil cylinder is synchronized with the movement, and has guaranteed the requirements such as the depth of parallelism of pole core.
(3) this structure adopts two stretching oil cylinders machine driven system that is synchronized with the movement, and has guaranteed the requirements such as the depth of parallelism of pole core.
(4) adopt unique drawing oil cylinder structure.
The structure and the using method of present embodiment are as follows:
(1) earlier each parts is leveled, assembled, oil cylinder, fuel tank are oil-filled, emptying pipeline air.
(2) start-up control button is opened oil pump, checks hydraulic system, adjusts stretching cylinder pressure.
(3) adjust forward and backward support stroke, make forward and backward support work identity distance from size greater than pole core length 30-80mm.
(4) the closed assembly frame is put in the pole core punching.
(5) compress, measure, adjust and under impaction state, penetrate, fastening stretching screw.
Wherein: Fig. 1, Fig. 2 are magnetic pole press-loading device of the present utility model, arrange two stretching oil cylinders in the pole core both sides, can be vacant go out the pole body position, after compressing, pole core penetrates stretching screw again, can deduct the frictional force that produces between stretching screw and pole lamination like this, generally only adopt 1/3 of traditional press-loading device pressure to compress, can reach the requirement of big-and-middle-sized Hydropower Unit pole core press mounting tightness fully; The utility model of this equipment also can increase trimmer easily in press-fiting process, guaranteed the geometry requirement of pole core.
The two ends, chassis respectively process two T-slots among the figure, are convenient to forward and backward support and compress tracks and use according to the forward and backward support location dimension of pole core length adjustment.Two stretching cylinders put together on fore-stock by bolt, and the reciprocating drive support of stretching cylinder piston rod compresses workpiece; Stretching cylinder is connected with hydraulic means by the turnover oilhole, produces synchronous oil pressure.
Fig. 3 is this equipment hydraulic system schematic diagram.
Compare: Fig. 4, Fig. 5 are traditional vertical lamination schematic diagram.Because traditional pole core press mounting equipment hydraulic cylinder is arranged in pole core 14 pole body positions, make the stretching screw at pole body position need penetrate the pole core punching earlier, increased the frictional force at screw rod position when press-fiting like this, pole core often compaction degree is not enough, especially for big-and-middle-sized Hydropower Unit rotor magnetic pole iron core, because size is long, quality does not reach standard-required.
