Technical Field

The invention relates to the technical field of deep hole detection, in particular to a deep hole internal defect detection device.

Background

Currently, in the production field, when many workpieces are used for processing the inner wall of a deep hole or chamfering, some defects occur, which requires a processing person to identify and find the defects. In the prior art, it is common to illuminate a deep hole with a flashlight and then visually inspect or inspect with a hand-held endoscope. However, when the inner wall or chamfer of the deep hole of the workpiece is rotationally inspected by the handheld flashlight or the endoscope, the defects on the inner wall or chamfer cannot be effectively identified, so that poor products enter the market and flow into the hands of customers, and quality problems are caused.
