The invention discloses an ultrasonic rolling strengthening device for a cylindrical fatigue test sample with a V-shaped notch, and relates to the technical field of strengthening devices. The ultrasonic rolling strengthening device comprises a rear cylinder cover, wherein one side of the rear cylinder cover is in threaded connection with a bolt, one side of the rear cylinder cover abuts against arubber ring, and one side of the rubber ring abuts against a piston. According to the ultrasonic rolling strengthening device for the cylindrical fatigue test sample with the V-shaped notch, throughthe arrangement of the piston and a spring, the strengthening device has the effects of being convenient to use and improving the performance of the anti-fatigue test sample; and through the matched arrangement of an amplitude-change rod and a rolling wheel, in the using process, ultrasonic rolling at the notch of the cylindrical fatigue test sample with the V-shaped notch can be achieved, so thatthe performance of the anti-fatigue test sample is improved, then the effects of simple structure and high practicability are achieved, and the purposes of strengthening and increasing the performance of the anti-fatigue test sample and reducing the surface roughness are achieved.
Description
technical field [0001] The invention relates to the technical field of strengthening devices, in particular to a V-notch cylindrical fatigue specimen ultrasonic rolling strengthening device. Background technique [0002] As a surface strengthening technology, ultrasonic rolling can produce high residual compressive stress on the surface of the workpiece by hitting the surface of the workpiece with high-frequency vibration, increase the hardness and reduce the surface roughness, and greatly improve the fatigue performance of the workpiece. However, there are relatively few ultrasonic rolling techniques applied to V-notch cylindrical fatigue samples at present, and fewer finished products. At present, with the improvement of manufacturing technology, the development of machinery manufacturing is gradually tending to the direction of high precision. However, this kind of V-notch cylindrical fatigue sample is easy to produce a large stress concentration at the V-notch, which af...
