Description
Technical field
The utility model relates to a kind of large-scale wind driven generator stator core stack-press device.
Background technology
In the large-scale wind driven generator stator manufacture process, often need press-fit,,, bring very big difficulty for press-fiting of stator iron core because of the volume of motor stator is very big to guarantee the stacking factor of stator core to stator core.Common process is to rely on the fastening force of bolt to come stator core is press-fited fastening, but that this power on circumference unshakable in one's determination of such method applies is inhomogeneous, and stacking factor is difficult to guarantee, can produce vibration after the motor long-time running.
The utility model content
The purpose of this utility model provides a kind of large-scale wind driven generator stator core stack-press device, and this stack-press device is simple in structure, and is easy and simple to handle, and the power on the stator core circumference applies evenly.
For solving the problems of the technologies described above, technical scheme provided by the utility model is: a kind of large-scale wind driven generator stator core stack-press device, this stack-press device includes hydraulic means, following centre mount, goes up centre mount and fixture block, described hydraulic means is provided with a telescopic shaft, and described telescopic shaft termination is provided with radial protrusion; Described centre mount down and last centre mount all are made as circle, and centre is provided with the through hole that telescopic shaft can pass; Described fixture block is provided with the groove that can block the telescopic shaft termination; Described telescopic shaft passes down the through hole of centre mount and last centre mount, and described fixture block blocks the termination of telescopic shaft.
The described periphery of centre mount down upwards is provided with push-down head vertically; The described periphery of going up centre mount is vertically to having seaming chuck, described push-down head and seaming chuck in the vertical direction over against.
Described seaming chuck and push-down head are equipped with 32～50.
Operation principle of the present utility model: when the large-scale wind driven generator stator core need press-fit, directly lift down workpiece on the centre mount, to go up centre mount and aim at the core pressing position, earlier telescopic shaft be passed down centre mount and last centre mount, the termination of blocking telescopic shaft with fixture block; Primer fluid pressure device then, the telescopic shaft retraction produces pulling force, and centre mount press-fits workpiece fastening with following centre mount in utilizations.
The advantage that the utlity model has: this product can be finished the process that press-fits of large-scale wind driven generator stator core in the most brief time, simple to operate, safe and reliable.Press-fit the efficient height than traditional screw rod, realized that the disposable of stator core press-fits, it is good that effect press-fits than traditional screw rod, avoided the discontinuity of traditional approach iron core, and the stacking factor of iron core is guaranteed.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment:
A kind of large-scale wind driven generator stator core stack-press device as shown in Figure 1, this stack-press device includes hydraulic means 1, following centre mount 2, goes up centre mount 3 and fixture block 4, described hydraulic means 1 is provided with a telescopic shaft 11, and described telescopic shaft 11 terminations are provided with radial protrusion; Described centre mount 2 down and last centre mount 3 all are made as circle, and centre is provided with the through hole that telescopic shaft 11 can pass; Described fixture block 4 is provided with the groove that can block telescopic shaft 11 terminations; Described telescopic shaft 11 passes down the through hole of centre mount 2 and last centre mount 3, and described fixture block 4 blocks the termination of telescopic shaft 11.
The described periphery of centre mount 2 down upwards is provided with push-down head 21 vertically; The described periphery of going up centre mount 3 is vertically to having seaming chuck 31, and seaming chuck 31 and push-down head 21 are equipped with 32～50, and seaming chuck 31 and push-down head 21 in the vertical directions one by one over against.
When press-fiting the large-scale wind driven generator stator core, move centre mount 3 earlier, stator core is directly lifted down on the centre mount 2, will go up centre mount 4 then and aim at the core pressing position.Like this, seaming chuck 31 and push-down head 21 contact the upper and lower at iron core respectively.The telescopic shaft 11 of hydraulic means 1 passes down centre mount 2 and last centre mount 3, the termination of blocking telescopic shaft 11 with fixture block 4; The primer fluid pressure device 1 then, and telescopic shaft 11 retractions produce pulling force, and seaming chuck 31 and push-down head 21 compress stator core by extruding.Workpiece is press-fited fastening by compressing centre mount 3.
This product structure is simple, and is simple to operate, press-fits the efficient height than traditional screw rod, realized that the disposable of stator core press-fits, and it is good that effect press-fits than traditional screw rod, avoided the discontinuity of traditional approach iron core, and the stacking factor of iron core is guaranteed.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
