Steel ball surface defect detection apparatus

Abstract

The invention discloses a device for detecting the surface damage of a steel ball. A feeding mechanism is connected with a feeding turnplate by a feeding passage. A plurality of detection cavities are arranged at the circle of the feeding turnplate. The position of the detection cavities is provided with a detection light source which provides illumination for the steel ball to be detected. A camera is arranged above the detection cavities. A salver and an unfolded turnplate are arranged below the feeding turnplate. The upper surfaces of the salver and the unfolded turnplate are flush. The middle part of the salver is provided with a guiding slot. A rotating shaft of the feeding turnplate penetrates the guiding slot of the salver to be connected with a stepping device. A salver support isarranged below the salver, the lower part of the salver support is fixed at the bottom of a detection slot. The top of the salver support is used for arranging the salver, and a tourelle is arranged between the salver support and the salver. A discharge hole is arranged on the salver and is communicated with a discharging mechanism. The discharging mechanism penetrates the bottom of the detectionslot. The unfolded turnplate is connected with a swing rotary drive set by a rotating shaft. The inside of the detection slot is provided with a swing mechanism which is connected with the salver fixedly. The device can detect the steel ball with any diameter and has high detection accuracy and efficiency.

Description

technical field [0001] The invention relates to a detection device, in particular to a steel ball surface defect detection device. Background technique [0002] The Chinese invention patent with the patent number ZL200310109912.4 discloses a detection method for surface defects of steel balls. The device for detecting the surface of steel balls in this patent includes a feeding mechanism, a feeding turntable, a partition and an unfolding turntable. The steel balls delivered by the feeding mechanism enter the detection chamber of the feeding turntable, and the partition mainly provides support for the feeding turntable. The unfolding turntable is located under the partition, and performs swinging and rotating motion to drive the steel ball in the corresponding hole of the partition and the feeding mechanism to rotate and expand the entire spherical surface, so that the camera mechanism can capture the entire surface of the steel ball and comprehensively detect the surface of ...
