Abstract
The utility model relates to an assembly tool. The assembly tool comprises a rotary handle, a connecting rod, a sleeve head and a brake rod, and is characterized in that a through hole is arranged at one end of the brake rod, the connecting rod is movably inserted in the through hole of the brake rod, positioning rods are respectively arranged on the two sides of the connecting rod on the brake rod in parallel, the lower end of the connecting rod is movably connected with the sleeve head, and the upper end of the connecting rod is movably connected with the rotary handle. The assembly tool has the beneficial effects that the operation is convenient and easy, the damage to the rotor caused by improper operation is avoided, the locking force can be ensured according to standard, and the assembly quality in the work procedures also can be ensured.
Description
Technical field
The utility model relates to the assembling of compressor, is specifically related to a kind of assembly tooling.
Background technology
In compressor assembling, need the axle of screw rotor be passed the endoporus of rotor, through bolt, the operation of this assembly process quality directly has influence on the runnability of compressor at the other end of rotor.When tie down screw; Rotor can rotate and then with spanner and rotate, and is difficult to guarantee assembly quality like this, and common measure is in the through flow hole of rotor, to insert the crowbar plugging; But the uncontrollable locking torque of this method, screw rod fixedly degree of tightness are not sought unity of standard; Another kind of way is to adopt pneumatic impact wrench; Make the pneumatic impact wrench fast rotational; Although rotor can turn round thereupon, but still can produce coupling mechanism force and clamping screw, the deficiency of this method is: because the screw rotor of assembling stage and rotor bearing are also not lubricated; And the axiality of locking the above two also can't guarantee the very high bearing of therefore easy damage precision.
The utility model content
The utility model is to the above-mentioned deficiency that exists in the compressor assembling, provide a kind of simple in structure, control easy assembly tooling.
The technical scheme that the utility model solves the problems of the technologies described above is following: comprise swing handle, extension bar, collet head and brake bar; Be characterized in; One end of said brake bar is provided with through hole, and said extension bar is actively plugged in the through hole of said brake bar, and the both sides of extension bar are parallel respectively on said brake bar is provided with backstay; The lower end of said extension bar flexibly connects said collet head, and the upper end flexibly connects said swing handle.
Said backstay is through the bolt of fixed by nut on said brake bar, on said backstay, also is provided with stop nut.
Said swing handle is a torque spanner.
The beneficial effect of the utility model is: owing to adopt this device; Rotor can and then not rotate when screwing screw rod, not only makes operation easy, has avoided the damage that rotor is caused because of misoperation; And can unify coupling mechanism force by standard, guarantee the assembly quality of this operation.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the user mode sketch map of the utility model.
In Fig. 1 and Fig. 2,1. swing handle; 2. extension bar; 3. brake bar; 4. nut; 5. collet head; 6. stop nut; 7. backstay; 8. rotor; 9. through flow hole; 10. screw rotor axle; 11. screw rotor.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; A kind of assembly tooling; Comprise swing handle 1, extension bar 2, collet head 5 and brake bar 3, an end of said brake bar 3 is provided with through hole, and said extension bar 2 is actively plugged in the through hole of said brake bar 3; The parallel respectively backstay 7 that is provided with in the both sides of said brake bar 3 extension bars 2, the lower end of said extension bar 2 flexibly connect said collet head 5, the upper end flexibly connects said swing handle 1.
Said backstay 7 is to be fixed on the bolt on the said brake bar 3 through nut 4, on said backstay 7, also is provided with stop nut 6.
Said swing handle 1 is a torque spanner.
As shown in Figure 2 is the practical view of the utility model, and the utility model operating process is: after screw rotor axle 10 is inserted in rotor 8, screw on the assembly tooling that bolt can adopt the utility model.Make the assembly tooling location in the through flow hole 9 with assembly tooling backstay 7 insertion motors; With assembly tooling collet head 5 and said screw rotor axle 10 sockets, fixing assembly tooling brake bar 3 just can utilize said assembly tooling swing handle 1 fastening bolt then; This moment is owing to receive the effect of brake bar opposite force; Rotor 8 is fixed, when adopting torque spanner simultaneously, is easy to guarantee coupling mechanism force by standard.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
