Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel dressing technology, specifically a mobile forming roller dresser. Background Technology

[0002] The dressing tool is moved to the starting position on the roller surface by a moving mechanism, and then the tool contacts the roller surface at a set speed and depth. During the dressing process, the tool removes material from the roller surface through cutting, grinding, or other methods, while the moving mechanism moves the tool along a set path, gradually shaping the roller to meet the requirements.

[0003] Meanwhile, patent application number 201320774325.6 discloses a grinding wheel forming roller dresser, including a grinding wheel box and a feed box connected to the grinding wheel box. The grinding wheel box is equipped with a grinding wheel, and the feed box is equipped with a roller. The radial feed of the roller is driven by a radial servo motor through a ball screw, and the rotation of the roller is driven by a radial servo motor through a synchronous belt. The roller is mounted on a roller shaft, and the two ends of the roller shaft are fixed support structures, supported by rollers and deep groove ball bearings.

[0004] However, in implementing the relevant technology, it was found that the aforementioned grinding wheel forming roller dresser has limitations in the existing technology. For grinding rotating parts with complex outer contours, such as parts with spherical outer surfaces, when a large number of parts are processed on-site, a dresser is required. The traditional approach is to equip each machine tool with one dresser, and the dressing method used is also very simple, using a diamond pen. This dressing efficiency is very low, and the configuration of one set per machine is costly, resulting in a significant waste problem. Summary of the Invention
