By means of the impeller disassembly device, when an impeller is disassembled, a force bearing point is on the impeller shaft sleeve and a motor shaft, so that balance of the impeller is not damaged, strength is good, disassembly speed is high, efficiency is high, and the impeller disassembly device is simple in structure and convenient to operate.
Description
Technical field
The utility model belongs to a kind of disassembling tool of machinery, is specifically related to a kind of impeller detacher, for the dismounting of small-sized axial flow fan and centrifugal blower fan blade wheel.
Background technique
Axial-flow blower and centrifugal blower are conventional machinery, in blower fan overhaul or fan bearing replacing situation, need impeller to dismantle, and due to blower fan High Rotation Speed, impeller and axle coordinate for transition fit, coordinate tightlyer, and dismounting is difficult.Impeller in tradition changes use Three-claw pull-horse, but because of the space of impeller demolition little, impeller hub strength weak, 3 Three-claw pull-horse easily makes impeller distortion when stressed, destroys the balance of impeller.
It is difficult that this product has solved existing draught fan impeller dismounting, and the technical barrier of rapid wear wheel member, provides a kind of easy to operate, dismantles effective desirable utensil.
Model utility content
For the defect existing in prior art, the utility model provides a kind of impeller detacher, is applicable to the dismounting of little space impeller, can not destroy the balance of impeller when dismounting; Dismounting speed is fast, and efficiency is high.
For reaching above object, the technical solution adopted in the utility model is: a kind of impeller detacher is provided, this stripping attachment comprises equalization block, described equalization block is provided with central through bore, in described central through bore, be equipped with strut, the top of described strut is provided with connection mouth, and the bottom of strut is provided with interchangeable joint, and described equalization block is provided with the bolt being connected with impeller sleeve.
Further, the connection mouth of described supporting bar top is provided with and can drives the proal hydraulic mechanism of strut.
Further, the central through bore of described equalization block is provided with internal thread, described strut be provided with described central through bore on the outside thread of screw-internal thread fit; The connection mouth of supporting bar top is provided with and can drives the proal spanner of strut.
Further, described equalization block is disc or square.
Further, described equalization block is provided with 2 bolts that are connected with impeller sleeve, and 2 described bolts are arranged in described equalization block symmetrically.
Useful technique effect of the present utility model is: adopt impeller detacher of the present utility model, during because of dismounting, force bearing point, on impeller sleeve and motor shaft, can not destroy the balance of impeller; In addition, equalization block and interchangeable joint are changed according to the size of impeller shaft hole, flexible and convenient to use; Make simply, easy to operate, intensity is good.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Embodiment 1
As shown in Figure 1, 2, be a kind of small impeller stripping attachment that the utility model provides, be applicable to the impeller demolition that space is little, wheel hub is thin, and can carry out on-the-spot dismounting.This stripping attachment comprises that disc or square equalization block 1, equalization block 1 are provided with central through bore, is equipped with strut 2 in central through bore, and the top of strut 2 is provided with connection mouth 3, and the bottom of strut 2 is provided with interchangeable joint 4.Equalization block 1 is provided with the bolt 5 being connected with impeller sleeve 6.The connection mouth 3 on strut 2 tops is provided with and can drives the proal hydraulic mechanism of strut 2.Adopt the stripping attachment of this structure, be applicable to impeller space larger, be not easy to manually operated blower fan, in order to alleviate working strength, can match with hydraulic mechanism.
For producing balanced forces in the time dismantling, equalization block 1 is provided with 2 bolts, and 2 bolts are arranged in equalization block 1 symmetrically.
As shown in Figure 3, when working state, 2 bolts 5 are fixed on impeller sleeve 6, interchangeable joint 4 is withstood to the spindle nose of motor shaft 7, drive strut 2 to travel forward by the hydraulic drive mechanism on connection mouth, because motor 8 maintains static, thereby strut 2 drive motor axles 7 do relative motion with impeller 9, and impeller 9 disassembles from centrifugal blower or axial-flow blower the most at last.In addition, equalization block 1 and interchangeable joint 4 can be changed according to the size of impeller shaft hole, flexible and convenient to use.
Embodiment 2
Embodiment 2 is with embodiment 1 difference, and the central through bore of equalization block 1 is provided with internal thread, strut 2 be provided with central through bore on the outside thread of screw-internal thread fit; The connection mouth 3 on strut 2 tops is provided with and can drives the proal spanner of strut, as shown in Figure 4,5.Adopt the stripping attachment of this structure, be applicable to impeller space less, be convenient to manually operated blower fan.
When working state, 2 bolts 5 are fixed on impeller sleeve 6, interchangeable joint 4 is withstood to the spindle nose of motor shaft 7, the spanner being rotatably connected on mouth drives strut 2 to travel forward, because motor 8 maintains static, thereby strut 2 drive motor axles and impeller do relative motion, and impeller 9 disassembles from centrifugal blower or axial-flow blower the most at last.
Impeller detacher of the present utility model is not limited to above-mentioned embodiment, and those skilled in the art draw other mode of execution according to the technical solution of the utility model, belongs to equally technological innovation scope of the present utility model.
