Problems solved by technology
[0004] At present, the profile detection of rollers is generally divided into two types: manual detection and sorting machine detection. Among them, the manual detection method can no longer meet the needs of modern industry due to low detection efficiency and high labor costs; and the sorting machine detection also exists. Problems such as single sorting equipment and small sorting range

The invention provides a roller profile detection method. The roller profile detection method comprises the following steps of 1, preparation work, wherein a roller is conveyed to a detection workbench; 2, detecting the profile of the roller: detecting the profile of the roller in a plurality of positions by adopting a detection mechanism, and obtaining the length, diameter and modification quantity values of the roller in the plurality of positions; and step 3, judging the profile of the roller: comparing the length, diameter and modification quantity values of the roller in multiple positions with the length, diameter and modification quantity design values of the roller, judging whether the length, diameter and modification quantity values of the roller meet the design requirements or not, and judging whether the profile of the roller has an ellipse or not. According to the invention, through detection of different positions of the roller, omnibearing detection of the roller is realized, and the detection precision is improved through a mode of averaging multiple detection results; and the diameter, the length and the modification amount of the roller can be detected at the same time.
Description
technical field [0001] The invention relates to the technical field of roller profile detection, in particular to a roller profile detection method. Background technique [0002] The roller is the key core component of the main bearing of the roadheader to bear the load and resist the impact. The small difference in the shape and size of the roller has a great influence on the working performance of the main bearing. If the difference in the shape and size of the roller is too large, the It will lead to local load concentration in the bearing area of the main bearing roller group, aggravate the friction and wear of the rollers and raceways, cause vibration and noise, and easily cause early failure of the main bearing of the roadheader. [0003] In order to ensure the normal operation of the main bearing of the roadheader and avoid economic losses caused by subsequent production, rollers with unqualified dimensions should be removed in time. [0004] At present, the profil...
