The invention discloses a torsion spring torsion measuring device, and belongs to the technical field of torsion spring torsion measurement. The device comprises an upper base which is in an inverted L shape, and the top of the upper base is fixedly connected with an upper plate of a spring tension and compression testing machine; the mandrel comprises a minimum shaft and a maximum shaft; the maximum shaft is partially and transversely embedded and fixed at the lower part of the upper base; the torsion sleeve comprises a small shaft, a middle shaft and a large shaft which are connected in sequence, a hole is drilled in the second end of the large shaft, the hole is formed in the first end of the minimum shaft in a sleeving mode, and a first groove is formed in a hole opening and used for containing a torsion spring supporting arm; a round hole is formed in the middle of the rotating hand wheel, and the rotating hand wheel is sleeved and fixed on the middle shaft; the bottom of the lower base is fixedly connected with a lower plate of the spring tension and compression testing machine, and the base is fixed above the lower base; according to the device, multiple purposes of the spring tension and compression testing machine can be easily realized; the device is simple in structure, wide in application range and suitable for various torsion springs.
Description
technical field [0001] The invention relates to the technical field of torsion spring torsion measurement, in particular to a torsion spring torsion measurement device. Background technique [0002] In aviation products, cylindrical helical torsion springs (hereinafter referred to as torsion springs) are usually used for compression and energy storage, or as elastic links in transmission systems, and the measurement of torsion spring torque is essential in determining the performance indicators of torsion springs part. [0003] At present, the torsion spring torque measurement work is mainly done on the torsion spring torque testing machine. The existing torsion spring torque testing machine has complex structure, high price, slow measurement speed and complicated operation. In response to this situation, people have developed some simple measuring devices, and these simple measuring devices are often made for a specific torsion spring, which has poor versatility and limite...
