Abstract
The utility model is a kind of impeller axle extracting apparatus used in separation shaft and impeller, horse, positioning disk and mandril are drawn including three-jaw fluid-pressure, the wherein described positioning disk upper surface is equipped at least three lugs, and the three-jaw fluid-pressure draws three pawl arm lower ends of horse hinged by bolt and the lug respectively；It is provided with center slot on the positioning disk and a plurality of positioning straight slot, the mandril are positioned in the slot of center, the screw rod for drawing horse with the three-jaw fluid-pressure is corresponding up and down.When use, through-hole or tapped blind hole are first drilled out on hub disk, hub disk upper surface and positioning disk lower face are tightened together with bolt, the screw rod for drawing horse is driven to push mandril again, to which impeller axle be ejected, there was only hub disk stress in the process due to entirely pulling out axis, blade is unaffected, so will not damaged blade.
Description
Technical field
The utility model is a kind of impeller axle extracting apparatus used in separation shaft and impeller.
Background technology
In motor device, mechanical equipment, blast apparatus or water pump needed for industrial production, impeller, damage are often housed
When need replacing, but allow its detached with axis be difficult operate and have certain danger.Traditional axis extracting apparatus generally uses 2 pawls
Or 3 pawl draw horse (electric hydaulic draw top multiple purpose aeroplane) to extract the axis being sleeved on impeller, but draw the claw clamping mode of horse in impeller
It can not find fixed point on wheel disc, can not use.Since impeller blade is relatively thin and is easily deformed, if with forcing press by impeller axle top
Go out, and meeting damaged blade, so that impeller operation noise is increased, efficiency declines, it could even be possible to causing entire wheel retirement.
Invention content
Place in order to overcome the deficiencies of the prior art, the utility model provides a kind of impeller axle extracting apparatus, above-mentioned to solve
Technical problem.
Technical solution used by the utility model is：A kind of impeller axle extracting apparatus, including three-jaw fluid-pressure draw horse, positioning
Disk and mandril, wherein the positioning disk upper surface is equipped at least three lugs, the three-jaw fluid-pressure draws three pawl arm lower ends of horse
It is hinged by bolt and the lug respectively；It is provided with center slot on the positioning disk and a plurality of positioning straight slot, the mandril are put
It is placed in the slot of center, the screw rod for drawing horse with the three-jaw fluid-pressure is corresponding up and down.In use, first drilling out through-hole on hub disk
Or tapped blind hole, hub disk upper surface and positioning disk lower face are tightened together with bolt, then drive and draw the screw rod of horse will
Mandril pushes, and to eject impeller axle, there was only hub disk stress in the process due to entirely pulling out axis, blade is unaffected, institute
With will not damaged blade.
A kind of impeller axle extracting apparatus, including jack, positioning disk and mandril, wherein the jack outer circle is equipped at least
Three hangers, the positioning disk upper surface are equipped at least three lugs, between the hangers of the jack and the lug respectively
It is actively coupled by rigid articulated jib；It is provided with center slot on the positioning disk and a plurality of positioning straight slot, the mandril are positioned over
It is corresponding up and down with the top of the jack in the slot of center.
Further, the jack is one kind in screw jack, hydraulic jack, electronic very heavy item.
Advantageous effect：The utility model is simple in structure, easy to use, and technology is reasonable, both saves manpower, the power that can be born
Bigger, intensity higher are suitable for the dismounting of various types size impeller axle.
Description of the drawings
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model,
Fig. 2 is the vertical view of positioning disk.
Specific implementation mode

2, wherein 3 upper surface of positioning disk is equipped at least three lugs 31, and three-jaw fluid-pressure draws three 12 lower ends of pawl arm of horse 1 to be provided with installation
Hole, it is hingedly fixed by bolt and lug 31 respectively.Center slot and a plurality of positioning straight slot 32 are provided on positioning disk 3, mandril 2 is put
It is placed in the slot of center, the screw rod for drawing horse 1 with three-jaw fluid-pressure is corresponding up and down.In use, first drilling out through-hole on the wheel disc of impeller 4
Or tapped blind hole, hub disk upper surface and 3 lower face of positioning disk are tightened together with bolt 5, then drive the screw rod for drawing horse
Mandril 2 is pushed, to eject impeller axle, there was only hub disk stress in the process due to entirely pulling out axis, blade is unaffected,
So will not damaged blade.It positioning straight slot 32 and generally uses radial arrangement, quantity is related with the size of positioning disk 3,
Usually 3-6 items.
Embodiment 2:
A kind of impeller axle extracting apparatus, including jack, positioning disk 3 and mandril 2, wherein jack outer circle are equipped at least three
A hangers, 3 upper surface of positioning disk are equipped at least three lugs 31, pass through rigid hinge respectively between the hangers and lug 31 of jack
Arm is connect to be actively coupled；Center slot and a plurality of positioning straight slot 32 are provided on positioning disk 3, mandril 2 is positioned in the slot of center, with thousand
