Problems solved by technology
[0002] With the refinement of mechanical production, torque wrenches are widely used in the processing and assembly of parts with specific torque requirements. However, high-precision torque wrenches are difficult to popularize due to their high price. If the actual torque does not match, the torque produced by the machine will not reach the rated value, resulting in loosening or excessive torque, causing damage to the bolts. However, only experienced technicians can determine the torque by hand feeling, which is greatly limited. Processing
[0003] At present, the existing torque wrenches with counting function are mostly mechanical, and can only record the effective number of times the torque handle is used or the number of times the torque is applied, but cannot accurately record the number of rotations of the torque wrench

The invention discloses an electronic counting type torque spanner which comprises a minitype power supply, a photoelectric transducer, an operational circuit, a display screen, a cover body and a common mechanical torque spanner, wherein the cover body is arranged on the spanner head of the common mechanical torque spanner; the display screen and the operational circuit are arranged out of the cover body; the minitype power supply and the photoelectric transducer are arranged in the cover body; and an annular grating is fixed on the cover body through an annular groove. The electronic counting type torque spanner can monitor the rotary number of turns of the torque spanner; as the rotary number of turns and the rotary torque are greatly relevant, the torque error due to efficacy loss or larger error of the torque spanner is avoided; realization of mechanical automation is facilitated to reduce the cost and improve the production efficiency; the numerical value is convenient to be memorized, so that experience accumulation is facilitated and meticulous process is facilitated; and the rotary number of turns of the torque spanner is displayed in real time to facilitate operation andprocessing of a worker.
