Abstract

The invention discloses a stably connected torque sensor. The stably connected torque sensor comprises a torque sensor body, an external connecting fixture and a screw, wherein a through hole is formed in one of the torque sensor body and the external connecting fixture, a threaded hole and a positioning hole which are coaxial are formed in the other one of the torque sensor body and the externalconnecting fixture, and the inside diameter of the positioning hole is greater than or equal to the nominal diameter of the threaded hole; the rod part of the screw comprises a polished rod part located on the back end and a threaded part located on the front end, and external threads which are matched with internal threads of the threaded hole are formed on the threaded part; and the torque sensor body and the external connecting fixture are stably connected by the screw, during connection, the threaded part and the polished rod part pass through the through hole, the threaded part is locatedin the threaded hole, part of the polished rod part is located in the positioning hole, and the polished rod part is in transition fit with the positioning hole. According to the stably connected torque sensor, sliding between the torque sensor body and the external connecting fixture can be preferably avoided, and normal use of the torque sensor is guaranteed, so that normal operation of the whole mechanical system can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of torque sensors, in particular to a firmly connected torque sensor. Background technique [0002] With the progress of industry, there are more and more applications of torque sensors. Most torque sensors are thick and heavy, and have a large size, which is not convenient for installation and use in places with high space requirements. Therefore, where the size is limited, the size of the torque sensor has to be reduced. In this way, higher requirements are put forward for the connection mode of the torque sensor and the external connection parts. [0003] The torque sensor mainly includes an inner ring, an outer ring, a force measuring beam and a strain gauge, the inner ring and the outer ring are connected by a force measuring beam, and the strain gauge is located on the force measuring beam. In practical application, the inner ring connection jig is connected to the inner ring, the outer ring connect...
