Abstract

The invention relates to a residual stress detection auxiliary device facing a non-ferromagnetic part. The residual stress detection auxiliary device comprises a non-ferromagnetic part clamping mechanism, a non-ferromagnetic part punching rough adjustment mechanism and a non-ferromagnetic part punching fine adjustment mechanism. The non-ferromagnetic part clamping mechanism can regulate the position of a clamping plate according to the size of the minimum cuboid containing body of the part. The non-ferromagnetic part punching rough adjustment mechanism can make a stress-strain piece located within the range of the fine adjustment mechanism. The non-ferromagnetic part punching fine adjustment mechanism can make the plane where the axis of a puncher fixing mechanism is located and the planewhere the punching position on the stress-strain piece is located in the nearly-perpendicular state so that precision of punching can be ensured. By means of the auxiliary device, the method of detecting residual stress through the blind hole method is applied to the aspect of residual stress detection of the non-ferromagnetic part, the accuracy of residual stress detection of the non-ferromagnetic part is improved, universality of a blind hole method residual stress detection device is increased, and operation of the device can be easier.

Description

technical field [0001] The invention relates to the field of blind hole method residual stress detection, in particular to an auxiliary device for clamping non-ferromagnetic parts and multi-angle drilling for blind hole method stress detection equipment. Background technique [0002] With the continuous development of industry, non-ferromagnetic parts such as aluminum alloy and magnesium alloy are more and more used in aerospace, rail, automobile and other fields due to their light weight. The residual stress existing in the non-ferromagnetic parts after processing will make them deform, affect the service life of the parts and even cause the parts to be scrapped. Therefore, it is necessary to detect the residual stress of the non-ferromagnetic parts after processing. The blind hole method is one of the mainstream methods for detecting residual stress at present, and compared with the X-ray method, it can detect the residual stress of parts more accurately. Compared with th...
