Description

Technical Field

[0001] The utility model belongs to the technical field of pulley production, in particular to a laser marking machine for pulley production. Background Art

[0002] Laser marking machine uses laser beam to mark the surface of various materials permanently. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to carve out exquisite patterns, trademarks and words. Laser marking machine is needed in the production and processing of automobile pulleys. According to the patent document with the authorization announcement number of CN217889878U and the name of "a pulley laser marking machine for automobile pulley production and processing", the servo motor drives the rotating shaft inside the positioning column to rotate. The rotating shaft rotates inside the No. 1 cavity and drives the driving gear to rotate synchronously. The driving gear and the driven gear rotate with each other. The meshing causes the driven gear to drive the connecting shaft to rotate. The connecting shaft uses the bearing seat to drive the threaded column inside the movable groove to rotate synchronously. The threaded column and the threaded barrel at the end of the fixed column rotate relative to each other, generating a thread force, which pushes the fixed column to extend from the inside of the movable groove to the outside of the positioning column, so that the fixed column is pressed against the inner wall of the central axis hole of the pulley. The limit block in the second cavity inside the fixed column limits the extension distance of the fixed column to prevent the fixed column and the threaded column from being separated, thereby stably and centrally fixing the pulley directly below the laser marking machine, facilitating accurate marking and avoiding position deviation, which affects the marking quality. However, the following defects still exist:

[0003] Although it can fix the pulley directly under the laser marking machine, the position of the pulley remains unchanged after being fixed, so it is difficult to mark different positions of the pulley, thereby reducing the diversity of laser marking options. Utility Model Content
