Problems solved by technology

Curved surface shaft parts, especially rotating shafts (such as axles), are prone to fatigue cracks, failure and fracture after long-term alternating loads during use, resulting in accidents
The tightly fitted shaft-hole parts are prone to fretting wear or fretting fatigue when working in a vibrating environment, resulting in failure of the parts, and the surface damage of the fittings, such as scratches and abrasions, will directly accelerate the crack initiation and fatigue of the curved surface parts fail
[0003] At present, the damage detection of curved surface parts at home and abroad is mainly to detect internal cracks by means of non-destructive testing such as ultrasonic, ray, and magnetic powder. The degree of surface damage will directly affect its service reliability

Abstract

The invention discloses an analytic apparatus of surface profile damage of curve-surface parts and a method thereof. The analytic apparatus comprises a shake-proof bench on which an X-axis ball screw module, at least one slide rail and a rotary apparatus for driving the curve-surface parts to rotate are arranged. A Z-axis vertical column apparatus is movably arranged on the slide rail. A Z-axis vertical ball screw module is fixedly on the Z-axis vertical column apparatus. A Y-axis ball screw module is arranged on the Z-axis vertical ball screw module. A magnetic grid ruler, which is matched with a magnetic grid ruler scale reading head that is installed on each of the X-axis, Y-axis and Z-axis vertical ball screw modules, is arranged on each of the X-axis, Y-axis and Z-axis vertical ball screw modules. The Y-axis ball screw module is provided with a CCD image sensor and a laser 2D profile collection instrument; the CCD image sensor, the laser 2D profile collection instrument and the magnetic grid ruler scale reading heads are all connected to a detection module. The X-axis, Y-axis and Z-axis vertical ball screw modules and the rotary apparatus are all connected to a control module.

Description

technical field [0001] The invention relates to a device for testing the integrity of the surface of a part, in particular to a device and method for analyzing the surface profile damage of a curved surface part. Background technique [0002] Curved surface shaft parts are one of the typical parts of various mechanical transmissions. They are mainly used to support transmission parts, transmit torque and bear loads, such as crankshafts, connecting rods, camshafts, half shafts and other parts. Curved surface shaft parts, especially rotating shafts (such as axles), are prone to fatigue cracks, failure and fracture after long-term alternating loads during use, resulting in accidents. The tightly fitted shaft-hole parts are prone to fretting wear or fretting fatigue when working in a vibrating environment, resulting in failure of the parts, and the surface damage of the fittings, such as scratches and abrasions, will directly accelerate the crack initiation and fatigue of the cu...
