Abstract
The utility model relates to a kind of hydraulic torque spanner, comprise sleeve, hydraulic spanner, brace, lower cartridge matches with bolt head to be tightened, the square falcon of the plug bottom of upper cartridge and hydraulic spanner matches, on adjacent two bolt heads to be tightened, cover has the hydraulic spanner with sleeve respectively, described brace is located between the plug of hydraulic spanner, and brace is provided with two tooth slot structures that coordinate with plug, and brace links together the plug of two hydraulic spanners.The utility model is owing to having two tooth slot structures that coordinate with plug on brace, adjacent two bolts and hydraulic torque spanner are linked together, can realize on curved surface the requirement of tightening without the dormant bolt of counter-force effect fulcrum, and two bolts can be tightened simultaneously, have greatly improved efficiency of assembling.
Description
Technical field
The utility model relates to a kind of hydraulic torque spanner.
Background technology
The connecting bolt of synchronous motor field spider pole shoe and rotating shaft is wanted all centrifugal force of bear rotor coil and pole shoe, not separated when motor moves with rotating shaft in order to ensure pole shoe, when assembling, magnetic pole need carry out pretension to connecting bolt, the pretightning force of bolt realizes by torque spanner, for the bolt that has high-torque requirement, this curved-surface structure of picture pole shoe, common hydraulic torque spanner can not find impetus and bears countertorque.
Utility model content
The purpose of this utility model is to overcome above defect, and a kind of high-torque hydraulic torque spanner of adjacent bolt as countertorque fulcrum of can usining on curved-surface structure is provided.
In order to reach above object, the technical solution of the utility model is, a kind of hydraulic torque spanner, comprise sleeve, hydraulic spanner, lower cartridge matches with bolt head to be tightened, the square falcon of the plug bottom of upper cartridge and hydraulic spanner matches, also comprise brace, on adjacent two bolt heads to be tightened, cover has the hydraulic spanner with sleeve respectively, described brace is located between the plug of hydraulic spanner, brace is provided with two tooth slot structures that coordinate with plug, and brace links together the plug of two hydraulic spanners.
Described sleeve and bolt junction are a word structure.
Described sleeve and bolt junction are cross structure.
Described sleeve and bolt junction are interior hex slot.
Technique effect of the present utility model is, owing to having two tooth slot structures that coordinate with plug on brace, adjacent two bolts and hydraulic torque spanner are linked together, can realize on curved surface the requirement of tightening without the dormant bolt of counter-force effect fulcrum, and two bolts can be tightened simultaneously, have greatly improved efficiency of assembling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, with reference to accompanying drawing, the present embodiment is the connecting bolt torque spanner structure of a synchronous motor field spider pole shoe, comprise sleeve 1, hydraulic spanner 3, sleeve 1 bottom matches with bolt head to be tightened, the square falcon of the plug 3-1 bottom of sleeve 1 top and hydraulic spanner 3 matches, also comprise brace 2, on adjacent two bolt heads to be tightened, cover has the hydraulic spanner 3 with sleeve 1 respectively, described brace 2 is located between the plug 3-1 of hydraulic spanner 3, brace 2 is provided with two tooth slot structures that coordinate with plug 3-1, the plug 3-1 of two hydraulic spanners 3 is linked together, after assembling, set required moment, 1 pair of bolt tightening of side's falcon band moving sleeve, when a bolt is tightened by moment, the moment of reaction is delivered to brace 2 from plug 3-1, brace 2 is stopped by the plug 3-1 of another torque spanner 3 while rotating, thereby realize the pretension of one of them bolt or paired pretension, according to the difference of bolt head, described sleeve 1 can be a word structure with bolt joint face, the structure such as cross structure or interior hex slot.
