A steel ball surface quality detection system

Abstract

The invention discloses a steel ball surface quality detection system, which includes a sorting mechanism and a detection mechanism, the sorting mechanism is located above the detection mechanism, and is used for providing the detection mechanism with steel balls of standard diameter to be detected , wherein the detection mechanism includes a frame, the frame is provided with an inner bracket, the inner bracket is provided with a rotatable eddy current detection bracket, and the eddy current detection bracket is provided with an eddy current detection probe, The eddy current detection bracket and the upper end of the inner bracket form a detection cavity for placing steel balls, and the eddy current detection bracket can rotate around the detection cavity; The steel ball will eventually correspond to the expanded structure derived from the steel ball. The scientific and reasonable improvement of the sorting mechanism and testing mechanism has improved the efficiency and accuracy of steel ball selection, avoided the steel ball stuck during the ball selection process and the steel ball center micro-movement during the detection process, and improved the quality of the steel ball. The accuracy of steel ball detection.

Description

technical field [0001] The invention relates to the field of steel ball surface quality detection, in particular to a steel ball surface quality detection system. Background technique [0002] Among the steel ball surface quality testing equipment, AVIKO series steel ball surface quality testing equipment is widely used in the world at present. This equipment adopts the meridian expansion method to realize the complete expansion of steel ball surface defects. As the core component of the steel ball surface quality testing equipment, the unrolling wheel is particularly easy to damage and needs to be replaced regularly, resulting in high maintenance costs. The steel ball rolls on the vertical surface under the rubbing of the upper and lower unfolding wheels of the detection mechanism, and it is inevitable to approach one side in the ball socket, that is, the steel ball must stick to the inner surface of the ball socket during the detection process.

As the core component of the steel ball surface quality testing equipment, the unfolding wheel is particularly easy to damage and needs to be replaced regularly, resulting in high maintenance costs

The steel ball rolls on the vertical surface under the rubbing of the upper and lower unfolding wheels of the detection mechanism, and it is inevitable to approach one side in the ball socket, that is, the steel ball must stick to the inner surface of the ball socket during the detection process. The position in the ball socket is also random, and the size of the defect or crack on the surface of the steel ball (including the length and depth of the crack) ranges from 0.001mm to 0.1mm, which is necessary for a very high-precision eddy current sensor. Cracks on the surface of the detector are very fatal, but the detection structure of the existing technology can hardly detect them, and it is easy to cause unqualified steel balls to flow into the market

Moreover, the structure of the sorting and feeding mechanism in the prior art is complicated, the processing cost is high, the efficiency is low, and the situation that steel balls are often stuck is prone to occur.
