Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the technical solution of the utility model.
Illustrate with reference to Fig. 1-Fig. 5, for a kind of turbine high-pressure outer shell cover nut tight dual-purpose torque spanner, it includes moment arm
1st, sleeve 1 and sleeve 23；The end face of sleeve 1 and the end face of sleeve 23 are connected as sleeve body, moment arm 1 with it is described
Sleeve body sidewall is affixed；
Multiple uniform 2-1 of gap slot one, the other end of sleeve 1 are circumferentially machined with the other end of sleeve 1
The 2-2 of multiple boss one that circumferentially formation is alternately arranged with the 2-1 of gap slot one on face and quantity is consistent；
Multiple uniform 3-1 of gap slot two, the other end of sleeve 23 are circumferentially machined with the other end of sleeve 23
Circumferentially formed and be alternately arranged with the 3-1 of gap slot two and multiple boss two 3-2, the 2-2 of boss one that quantity is consistent and convex on face
The 3-2 of platform two groove match with corresponding cover nut respectively.Moment arm 1 and the sleeve body sidewall weld.
Illustrate referring to Fig. 5, further, sleeve 1 and sleeve 23 are coaxially arranged.It is arranged such, ensures tight cover spiral shell
When female, sleeve body uniform force.Actual tight nut needs in order to meet, the internal diameter of sleeve 23 is less than the internal diameter of sleeve 1.
In this way, material is saved, it is light easy to use.Preferably, sleeve 1 and sleeve 23 use circular sleeve.
Illustrate referring to Fig. 1, moment arm 1 is board-like moment arm.It is arranged such, it is easy to use, meet to be actually needed.
