The invention relates to an adjustable torque screw connection device for screwing threaded connectors. The device comprises a torque input part, a torque output part, a torque transmission part and alimiting part, a first cylindrical cavity with two openings in the front and rear ends is formed in the torque input part, and the rear end of the torque input part is connected with external torque,and the torque input part can rotate under the effect of the external torque; the rear end of the torque output part is arranged in the first cavity, the front end of the torque output part is exposed out of the first cavity and connected with a universal threaded connector screwing tool, and a second cylindrical cavity with an opening in the end surface is formed in the rear end of the torque output part; the torque transmission part is arranged on the side wall of the second cavity and used for transmitting the torque from the torque input part to the torque output part; the limiting part is arranged in the first cavity or the second cavity and used for taking an limiting effect on the torque transmission part. The screw connection device has the function of controlling the thread screwing torque and can be used when limited by the structure of equipment and the external installation space.
Description
technical field [0001] The invention relates to an adapter device, in particular to an adjustable torque adapter device for tightening threaded connectors. Background technique [0002] As a precise electromechanical device, radar requires high assembly accuracy during equipment integration, and a large number of threaded connections require tightening torque. However, due to the influence of the structure of the equipment itself and the external installation space, the existing torque control tools are not fully suitable for various assembly environments of radar equipment due to their large dimensions and inconvenient use. Adjustable torque transfer device for joints. Contents of the invention [0003] In order to solve the problem that the existing torque control tools for tightening threaded connectors are large in size and inconvenient to use in a narrow installation space, the present invention provides an adjustable torque transfer device that can be used for tight...
