The utility model is big with the impeller amount of unbalance of static balancing method balance at the cantilever type impeller, balance quality difference and can not satisfy the quality of product requirement so the utility model adopts dynamic balance method, has thoroughly solved the problems referred to above, make the product running steadily, improved quality of product greatly.
The purpose of this utility model is achieved in that a kind of dynamic poise device that is applied to the cantilever type impeller, comprise: mandrel, impeller, it is characterized in that: the right-hand member of described mandrel is connected with impeller, mandrel and impeller are placed on the roller of balancing stand I and balancing stand II, the upper end of balancing stand I and balancing stand II is connected with travel(l)ing rest, one balance briquetting is arranged on the travel(l)ing rest, described balance briquetting is directly over mandrel, contact with mandrel, the balance briquetting is by the locking of the lock handle I on the travel(l)ing rest, and balancing stand I and balancing stand II are provided with sensor.
Described mandrel is threaded with impeller, by stop collar restriction screw-in depth.
Described travel(l)ing rest is provided with lock handle II.
Described mandrel is provided with a Balance disc, Balance disc is placed on the left side of balancing stand I, the balancing stand worker is in the left side of balancing stand II, and the moment sum that the moment that the gravity that makes Balance disc produces balancing stand II roller fulcrum and the impacting force of two balance briquettings produce balancing stand II roller fulcrum equals the moment that the gravity of impeller produces balancing stand II upper roller fulcrum.
The left end of described mandrel is provided with and connects cover and universal joint, and universal joint links to each other with dynamic balancing machine, and dynamic balancing machine is provided with dial.
The utility model has the advantages that: simple in structure, adopt dynamic balance method, thoroughly solved statically balanced problem, improved the precision of balance, make the product running steadily, improved quality of product greatly.

Below in conjunction with drawings and Examples the utility model is elaborated.
Embodiment
Among Fig. 2 and Fig. 3, a kind of dynamic poise device that is applied to the cantilever type impeller, comprise: mandrel 17, impeller 20, it is characterized in that: the right-hand member of described mandrel 17 is connected with impeller 20, mandrel 17 is placed on the roller 24 of balancing stand I16 and balancing stand II18, and the upper end of balancing stand I16 and balancing stand II18 is connected with travel(l)ing rest 25.
One balance briquetting 21 is arranged on the travel(l)ing rest 25, and described balance briquetting 21 contacts with mandrel 17 directly over mandrel 17, and balance briquetting 21 is by the locking of the lock handle I22 on the travel(l)ing rest 25, and balancing stand I16 and balancing stand II18 are provided with sensor.
Described mandrel 17 is threaded with impeller 20, by stop collar 19 restriction screw-in depths.
Described travel(l)ing rest 25 is provided with lock handle II23.
Described mandrel is provided with a Balance disc 15, Balance disc 15 is placed on the left side of balancing stand I16, balancing stand I is in the left side of balancing stand II18, and the moment sum that the moment that the gravity that makes Balance disc 15 produces balancing stand II18 roller 24 fulcrums and the impacting force of two balance briquettings 21 produce balancing stand II18 roller fulcrum equals the moment that the gravity of impeller 20 produces balancing stand II18 upper roller 24 fulcrums.
The left end of described mandrel is provided with and connects cover 14 and universal joint 13, and universal joint 13 links to each other with dynamic balancing machine 11, and dynamic balancing machine 11 is provided with dial 12.
Mandrel right-hand member T type screw thread is packed in the corresponding T type of the impeller threaded female, place restrictions on the T type with limiting stopper and be threaded into the degree of depth, mandrel and impeller are put into HM40 balance frame I, on the roller of II, with balancing stand I, II upper end travel(l)ing rest puts down, locked with lock handle 1, adjust the balance briquetting again and be adjacent to mandrel and locked with lock handle 2, the 450Kg because the cantilever type impeller weighs, so, must add Balance disc at the left end of balance bracket I, make Balance disc center of gravity place weight ask that to balancing stand II roller fulcrum the impacting force that the moment of generation adds two balance briquettings again equates to the moment that balancing stand II roller fulcrum produces substantially with impeller center of gravity weight.
