Abstract

The utility model discloses a puller used for pulling two half ferrules. A screw nut sleeve(7)is arranged on a mighty screw mandrel(4)of the puller. A circumferential groove is arranged on the screw nut sleeve(7). One end of each of the two half ferrules(3)is installed in the circumferential groove of the screw nut sleeve(7). An anti-disengaging sleeve(5)is arranged on the outer circumferences of the screw nut sleeve(7) and the two half ferrules(3). The puller is used for disassembling of a fan blade and can quickly disassemble the fan blade without causing damages to the fan blade.

Description

Two halves sleeve chest expander
Technical field:
The utility model relates to the machinery maintenance technical field of tools, especially a kind of two halves sleeve chest expander.
Background technology:
The local convection rotary type blower fan that mine uses down, very difficult to the fan blade dismounting in repair procedures because its blade structure is special, waste time and energy in the unloading process, cause fan blade to damage again easily.
The utility model content:
The purpose of this utility model provides a kind of two halves sleeve chest expander, is used for the dismounting of impeller of blower, and the quick release fan blade does not damage fan blade again.
The technical solution of the utility model is: described a kind of two halves sleeve chest expander, on the powerful screw mandrel of this chest expander, the screw sleeve is housed, on the screw sleeve, be provided with circumferential groove, one end of two halves cutting ferrule is packed in the circumferential groove of screw sleeve, is set with the anti-cover of opening on the periphery circle of screw sleeve and two halves cutting ferrule.
Termination at described powerful screw mandrel is provided with spherical groove, and anti-pivoted housing is equipped with at the position in the periphery circle of screw sleeve.
The utility model quick release fan blade does not damage fan blade again, and promptly economy is practical again, can alleviate working strength of workers, increases work efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Specific embodiments:
As shown in fig. 1, on powerful screw mandrel 4 of the present utility model, screw sleeve 7 is housed, on screw sleeve 7, be provided with circumferential groove, one end of two halves cutting ferrule 3 is packed in the circumferential groove of screw sleeve 7, on the periphery circle of screw sleeve 7 and two halves cutting ferrule 3, be set with the anti-cover 5 of opening, termination at powerful screw mandrel 4 is provided with spherical groove, and anti-pivoted housing 6 is equipped with at the position in the periphery circle of screw sleeve 7 in addition.
During the dismounting fan blade, steel ball 8 is placed in the centre bore of motor shaft head 2 of local convection rotary type blower fan, spherical groove with powerful screw mandrel 4 terminations withstands, at this moment, to prevent out that cover 5 moves backward, the other end of two halves cutting ferrule 3 is fastened in the circumferential groove of fan blade 1 of local convection rotary type blower fan, to prevent out that again cover 5 moves forward, block two halves cutting ferrule 3, prevent that two halves cutting ferrule 3 disconnects in groove, fixing then anti-pivoted housing 6 rotates powerful screw mandrel 4 again, and the fan blade 1 with local convection rotary type blower fan unloads from portable blower motor shaft head 2 gradually.
