Survey Special drill jig.
Background technology
Balancing each other certainly in object is remained in after the effects that residual stress refers to elimination external force or non-uniform temperature field
Internal stress.Mechanical processing and reinforcement process can cause residual stress.Such as cold drawing, bending, machining, rolling, shot-peening, casting
It makes, forge and press, welding and metal heat treatmet etc., because uneven plastic deformation or phase transformation may all cause residual stress.Residual stress
Usually harmful, if part is after unsuitable heat treatment, welding or machining, residual stress can cause part to stick up
Bent or torsional deformation, or even cracking.Or quenched, grinding rear surface will appear crackle.The presence of residual stress will not be stood when having
Show as defect, and when part being superimposed because of working stress and residual stress at work, it is more than strength degree to make total stress
When, just cracked and fracture.The measurement method of residual stress has Blind Hole Method residual stress measurement, magnetic survey method residual stress measurement
With X-ray diffraction method residual stress measurement.
The principle of Blind Hole Method residual stress measurement is drilled on primary stress field in the state of the equilibrium, to remove a part
Metal with stress, and the stress in Near Circular Hole In A part metals is made to be relaxed, drilling destroys original stress equilibrium
State and so that stress is redistributed, and new stress equilibrium is presented, to make the metal of Near Circular Hole In A be subjected to displacement or strain, leads to
The deformeter of excessive sensitivity measures the dependent variable after drilling, so that it may to calculate the stress value of former stress field.Since bearing race exists
It is not easy clamping when drilling, drilling quality can not ensure, be influenced on residual stress measurement very big.
