Ceramic ball surface quality detection device

Abstract

The invention relates to a ceramic ball surface quality detection device, comprising a rack (1), a clamping assembly, a ball lifting assembly, a ball vertically rotating assembly, a ball horizontally rotating assembly and a microscope swinging assembly; wherein the clamping assembly, the ball lifting assembly, the ball vertically rotating assembly and the ball horizontally rotating assembly are respectively arranged on the rack (1); the claming assembly and the ball vertically rotating assembly are horizontally arranged on the horizontal platform surface of the rack (1), the ball horizontally rotating assembly and the ball lifting assembly are arranged below the horizontal platform surface of the rack (1), and the microscope swinging assembly is arranged above the horizontal platform surface of the rack (1). The invention can realize detection on ball by virtue of parallel spherical zone expansion method or spiral spherical zone expansion method, an electromagnet is adopted for clamping, so as to improve clamping speed, and detection speed is improved.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to a ceramic ball surface quality detection device. Background technique [0002] With the vigorous development of the world's aviation and aerospace industries, silicon nitride ceramics have excellent comprehensive performance and all the important characteristics required by rolling bearings. Therefore, it is essential to test the surface quality of ceramic balls. The inspection technology based on image processing is not only suitable for ceramic materials, but also for other materials, and can detect small defects. Ceramic bearings have broad application prospects and increasingly obvious market space in the fields of pharmaceuticals, chemicals, textiles, aerospace, metallurgy, machinery, petroleum, transportation, electronics, and military equipment. With the increasing application of ceramic materials, the detection of ceramic materials is also very important. [0003] At prese...

Problems solved by technology

Each inspection method is capable of detecting a certain size and shape of the surface and this surface defect, but has its own limitations

Moreover, the ball is detected by the helical conjugate axis expansion method, so there are two disadvantages in actual use: 1) The movement between the expansion wheel and the ceramic ball is a combination of rolling and sliding, and its trajectory cannot be accurately determined; 2. ) The surface of the unfolding wheel loses its original shape after being worn out, so that the ceramic ball cannot be unfolded according to the designed trajectory, so there will be a blind area during detection
