An Integral Axial Texture Grinder for Ultrasonic Vibration Cylindrical Fatigue Samples

Abstract

The invention discloses an ultrasonic vibrating cylindrical fatigue sample integral type axial texture grinder, relates to the technical field of axial texture grinders, including an ultrasonic generator and a workbench, the top of the slider is fixedly connected with an ultrasonic base, and the ultrasonic base The internal fixed connection has a spring shaft. In the present invention, by setting an ultrasonic generator and adding ultrasonic vibration, the whetstone is vibrated at a high frequency perpendicular to the grinding direction according to a certain frequency and a certain amplitude, thereby improving the processing efficiency, high processing efficiency and making the surface of the metal fatigue sample produce Uniform and fine cut marks, reduced surface roughness, and improved machining accuracy. By setting the spring shaft, the spring outside the spring shaft can be adjusted through the adjustment nut. When grinding, the deformation of the spring can be changed, thereby changing the whetstone. Grinding pressure on metal fatigue samples, and can stabilize the pressure when the position of the adjusting nut remains unchanged to ensure the grinding effect.

Description

technical field [0001] The invention relates to the technical field of axial texture grinders, in particular to an integral axial texture grinder for ultrasonic vibration cylindrical fatigue samples. Background technique [0002] At the present stage, the machining of rotating bending fatigue samples is generally done by turning. This machining method not only has low machining accuracy, but also inevitably leaves machining textures on the machined surface, which has a negative impact on the surface quality of parts. Great constraints. The more advanced processing method is grinding, which can meet the high-precision requirements of fatigue samples, but the processing process is cumbersome, and burns appear on the surface of the sample, and it is not easy to process fatigue samples with complex structures. The above two processing methods process the circumferential texture on the surface of the fatigue sample, which is harmful to the fatigue strength and does not meet the ...

Problems solved by technology

However, for some workpieces with special structures, the operation of the grinding machine is complicated, the volume is large, and the processing accuracy is low. Manual grinding and polishing cannot control the consistency of parameters such as grinding speed, and the grinding efficiency is low.

Grinding is the final processing procedure of precision parts. The quality of surface processing directly affects the performance of workpieces and the reliability of machinery and equipment. Traditional grinding methods cannot effectively remove the processing texture on the surface of shaft parts.
