Abstract

The invention discloses an automatic stress test drilling machine. The automatic stress test drilling machine comprises a base and a gun drill part, wherein the gun drill part is erected by the base and comprises a driving device and a gun drill driven by the driving device to move. The automatic stress test drilling machine and the working method thereof, provided by the invention have the advantages that the drilling machine is capable of realizing an automatic driving function in comparison with controlling drilling depth and accuracy manually, and is compact in structure and more convenient and accurate in operation. The gun drill part swings at a certain angle around a pin roll, so that an angle between the gun drill part and a to-be-measured sample surface can be finely adjusted to adapt to stress test drill holes at various positions with complex structures. The drilling machine provided by the invention can realize the adjustment on arranging angle and height of the base through stand bars arranged at the bottom part of a rack plate to ensure the stability of work. The gun drill provided by the invention is fixed by adopting a collet chuck manner, so the high-precision positioning accuracy of the gun drill is much facilitated. According to the automatic stress test drilling machine and the working method thereof, a longitudinal frame and a horizontal frame are used to realize the quick positioning of the gun drill part in all sides in a plane.

Description

technical field [0001] The invention relates to an automatic stress test drilling machine and a working method thereof, belonging to the technical field of material residual stress test. Background technique [0002] In the process of machining, the non-uniform plastic deformation caused by the change of external force and temperature is the main reason for the generation of residual stress. In the process of casting, forging, welding and various cutting processes, the workpiece will be redistributed due to the external force and temperature, which may affect the size and shape accuracy of the parts and the assembly accuracy of the parts, reducing the The fatigue resistance, stress corrosion resistance and creep cracking resistance of parts ultimately affect the performance and service life of machinery and equipment. Therefore, it is crucial to test the stress phase of raw materials, parts or equipment. [0003] There are many methods for testing residual stress, such as ...
