Description
Technical field
The utility model is related to a kind of fastening devices, especially a kind of fastening device suitable for inner cavity small space.
Background technology
Existing common torque spanner, in the operating process for carrying out fastening or torque calibration, torque spanner, torque turn
After connecing spanner and being connected by fastener, rotation axis collects point-blank, to realize the tightening operation of fastener.
And for the narrow position of intracavity space, as in the accessory drive casing of aircraft or engine, since fastener operating space is small,
Existing torque spanner can not directly touch these fasteners, and fastening and torque can not be carried out so as to cause these fasteners
Calibration, if certain fasteners can not be tightened by regulation torque, it will cause not leaned on or deflection by fastenings assembly, in turn
The inordinate wear for leading to part, seriously affects product quality.
Invention content
The purpose of this utility model is to provide a kind of fastening device suitable for inner cavity small space, can be to common torque
The fastener that spanner can not be touched directly carries out fastening and the calibration of torque, to realize the correct operation to fastener, ensures
Product quality.
The specific technical solution of the utility model is that the fastening device suitable for inner cavity small space includes torque
Spanner, adapting rod, the torque spanner connects adapting rod, and adapting rod is driven to rotate, the other end and fastener of adapting rod
Cooperation is provided with bending part on the adapting rod, and adapting rod can be made to avoid inner body, reach fastener locations and with
Appended claims.
The utility model has redesigned switching bar part, for different use environment and space characteristic, will turn pull rod
It is arranged to curved shape, to accurately reach fastener locations, realizes the matching requirements of fastener.Meanwhile turning fully considering
The size of fitting bending part, so that it may to carry out calibration torque by torque spanner, ensure that the assembling quality of product.Therefore,
The utility model realizes the requirement in the small space of inner cavity, and firm and torque calibration is carried out to fastener, ensures
Assembling quality.
