The torque calibration device comprises a torque wrench, a first torque limiter, a rack, a first transmission shaft, a first hexagonal chuck, a second hexagonal chuck, a second torque limiter and a second transmission shaft, the rack is provided with two transmission shaft screw holes, and the first transmission shaft and the second transmission shaft are inserted into the rack; the first torque limiter is fixed on the rack, and the first hexagonal chuck is clamped on a locking nut of the first torque limiter; the second torque limiter is fixed on the rack, and the second hexagonal chuck is clamped on a locking nut of the second torque limiter; during calibration, the first transmission shaft and the second transmission shaft are fastened on the rack through the screws for torque calibration, and during inspection, the screws are detached, the first transmission shaft or the second transmission shaft is rotated through the torque wrench, and inspection of the calibrated torque is completed. According to the invention, torque calibration and inspection can be rapidly and effectively carried out on the torque limiter, the torque setting precision is improved, and the reliability of equipment operation is ensured.
Description
technical field [0001] The invention relates to a torque calibration device for a torque limiter, which is applied to the press industry and belongs to the technical field of mechanical engineering. Background technique [0002] The torque limiter is an important device used to connect the motor and the transmission shaft. Its main function is overload protection. When the required torque exceeds the set value due to overload or mechanical failure, it will limit the torque transmitted by the transmission system in the form of slippage. After the situation disappears, the connection will be restored on its own. In the process of use, the torque setting is too large to play a protective role, the torque setting is too small, and the torque limiter slips. The torque set by the torque limiter has no reliable device for effective setting and inspection, which seriously affects the reliability and stability of the equipment operation. SUMMARY OF THE INVENTION [0003] The tech...
