Abstract
The utility model provides a fan impeller disassembling device, includes backup pad and pushing force bolt, the center of backup pad is equipped with the pushing force bolt hole, the pushing force bolt hole is the silk hole, the backup pad uses the pushing force bolt hole to be equipped with two stress bolt holes as central symmetry, the pushing force bolt revolves the dress and is in in the pushing force bolt hole, the position of pushing force bolt hole is corresponding with fan wheel's motor shaft position, the position in stress bolt hole is corresponding with the position of fan wheel's impeller screw thread, and this device improves maintenance efficiency, reduces intensity of labour, saves working time to do not cause any damage to the impeller.
Description
Technical field
This utility model relates to a kind of fan impeller disassembling device.
Background technology
Production scene uses small compact radial blower fan more, and maintenance workload is relatively big, overhauls in particular for dismounting impeller.Because the construction features of centrifugal blower fan blade wheel, it is impossible to use three feet to draw horse, the most basic employing carrying pole type draws horse or is dismantled by force by impeller by external force.Shoulder pole draws horse size to have to be larger than impeller outer diameter, and quality is relatively big, and aspect is not carried, and is also inconvenient to use.Dismantle by force by external force, generally use copper rod and beat, because impeller making material is relatively thin, easily impeller is beaten deformation during beaing, cause wheel retirement.
Utility model content
This utility model provides a kind of overhaul efficiency that improves, reduction labor intensity for the deficiencies in the prior art, saves labor time, and impeller does not cause a kind of fan impeller disassembling device of any damage.
This utility model adopts the following technical scheme that realization: a kind of fan impeller disassembling device, including gripper shoe and top power bolt, the center of described gripper shoe is provided with top power bolt hole, described top power bolt hole is silk hole, described gripper shoe is arranged with two stress bolt holes centered by the power bolt hole of top, described stress bolt hole is waist hole, described top power bolt spinning is in the power bolt hole of described top, the position of described top power bolt hole is corresponding with the motor shaft position of draught fan impeller, and the position in described stress bolt hole is corresponding with the position of the impeller screw thread of draught fan impeller.
The end of described top power bolt is taper.
As preferably, described gripper shoe is steel plate.
Owing to using said structure, gripper shoe is fixed on the impeller screw thread of draught fan impeller by this utility model by stress bolt, by power bolt top, top piezoelectricity arbor, utilize the principle of active force and counteracting force, thus conveniently impeller is dismantled with motor shaft, top power bolt end is taper, contact with the motor shaft central point groove of draught fan impeller when screwing in, when preventing top power bolt from screwing in, the strong point arbitrarily swings, owing to stress bolt hole is waist-shaped hole, thus can be adjusted according to the difference of the difference of blower fan model and impeller size, it is widely used in the blower fan that the diameter of axle is 20-50mm.
In sum, the provision for disengagement of this device is simple, convenient, it is simple to carrying, impeller is not caused any damage by unloading process.Dismantlement work can be carried out in the case of not dismantling motor foundation bolt simultaneously.This device can be adjusted according to the difference of the difference of blower fan model and impeller size, is widely used in the blower fan that the diameter of axle is 20-50mm.
Accompanying drawing explanation
Fig. 1 is structural representation in use of the present utility model.
Fig. 2 is the structural representation of this utility model gripper shoe.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
As shown in Figure 1, 2, a kind of fan impeller disassembling device, including gripper shoe 1 and top power bolt 4, the center of described gripper shoe 1 is provided with top power bolt hole 3, described top power bolt hole 3 is silk hole, described gripper shoe 1 is arranged with two stress bolt holes 2 centered by the power bolt hole 3 of top, described stress bolt hole 2 is waist hole, described top power bolt 4 spinning is in described top power bolt hole 3, the position of described top power bolt hole 4 is corresponding with motor shaft 7 position of draught fan impeller 8, and the position in described stress bolt hole 2 is corresponding with the position of the impeller screw thread 6 of draught fan impeller 8.The end of described top power bolt 4 is taper.
Gripper shoe is that steel plate makes, and centre position processing screw thread is top power bolt hole 3, and two ends processing waist through hole is stress bolt hole 2.Stress bolt 5 is utilized gripper shoe 1 to be fixed on the impeller screw thread 6 of impeller 8, by power bolt hole 3 precession top, top power bolt hole 3 tapered for end band, and continue force, top power bolt 4 is contacted with motor shaft 7, and under the active force effect with counteracting force, gripper shoe will progressively outer be moved, and drive stress bolt, and then impeller, finally make impeller depart from motor shaft, impeller is taken out.
Claims (4)
