Abstract

The invention provides an inner cylinder surface defect detection method. The method comprises a traditional rotary table and an improved conveyor belt; a traditional to-be-detected inner cylindricalsurface is clamped in the center of the top of the traditional rotary table; a traditional single industrial camera is bolted to the right side of the top of the traditional to-be-detected inner cylindrical surface; improved to-be-detected inner cylindrical surfaces are sequentially clamped at the top of the improved conveying belt from left to right; and a plurality of improved industrial camerasare sequentially bolted to the tops of the improved to-be-detected inner cylindrical surfaces from left to right. Through the structural cooperation of the improved conveyor belt, the improved to-be-detected inner cylindrical surfaces and the improved industrial cameras, the precision and integrity of the collection surfaces of the improved to-be-detected inner cylindrical surfaces are improved;a mechanical structure and detection process are greatly simplified; a clamping device and a rotary table necessary for a traditional scheme are not needed; multiple stations do not need to be arranged; and detection speed is improved, and workpieces can be detected only by being conveyed through the conveyor belt.

Description

technical field [0001] The invention relates to the field of component detection, in particular to a method for detecting defects on the surface of an inner cylinder. Background technique [0002] Defect detection usually refers to the detection of surface defects of objects. Surface defect detection uses advanced machine vision detection technology to detect defects such as spots, pits, scratches, color differences, and defects on the surface of workpieces. [0003] When the user inspects the internal surface defects of parts such as bearing rings, the traditional method often needs to use a clamping device to place the part on the turntable, and the turntable rotates once. At one angle, the camera collects image data once, and the detection of a part needs to be collected multiple times. In this way, a series of mechanical structures must be added, such as a turntable and a clamping device, and a separate station needs to be set up. At the same time, the process is cumbers...
