Description

Technical Field

[0001] The utility model relates to the technical field of laser marking machines, and particularly relates to a laser marking machine with a limiting function. Background Technique

[0002] A laser marking machine uses a laser beam to permanently mark various different material surfaces. The marking effect is achieved by evaporating the surface layer material to expose the deeper layer material, thereby engraving exquisite patterns, trademarks, and characters.

[0003] At present, it is difficult for the existing laser marking machines to effectively limit the workpieces during marking, so that the workpieces are prone to offset during processing, which in turn causes the marking to be offset. Secondly, since some workpieces need to be marked on both sides, when marking on both sides, the workpieces need to be removed from the marking machine, flipped, and then stabilized above the marking machine, which increases the complexity of workpiece marking.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] In the present utility model, when marking the other side of the workpiece, press down the pushing block to drive the connecting plate to move. The movement of the connecting plate drives the clamping block to move downward. The downward movement of the clamping block squeezes the return spring, causing the clamping block to move away from the inside of the clamping groove. As a result, the connecting block is no longer limited. Rotate the rotating frame to drive the rotating block to rotate. The rotation of the rotating block drives the limiting frame to rotate, thereby driving the workpiece away from below the laser marking frame. Flip the workpiece so that the limiting frame rotates along the inner wall of the rotating groove through the rotating block, and thus the workpiece completes the flipping operation. Rotate the rotating frame to flip the connecting block above the stabilizing block. The return of the return spring drives the clamping block to move upward, causing the clamping block to re-enter the inside of the clamping groove, thereby stabilizing the connecting block and thus stabilizing the flipped workpiece, facilitating the double-sided marking operation of the device on the workpiece, and thereby reducing the tediousness of double-sided marking.

[0013] In the present utility model, place the workpiece above the support rod so that the workpiece is located between the clamping frames. Move the clamping frames, and the clamping frames move towards one side of the workpiece. The movement of the clamping frames drives the limiting sliders to move along the inner wall of the limiting chute, and at the same time, the clamping frames drive the moving plates to move along the inner wall of the sliding groove. After the clamping frames clamp the workpiece, rotate the threaded rod through the threaded groove to make the threaded rod move downward. The downward movement of the threaded rod drives the rubber block to squeeze the top of the rubber sheet. The clamping frames are stabilized through the settings of the rubber block and the rubber sheet. The workpiece is marked through the laser marking frame, enhancing the limiting effect of the device on the workpiece and avoiding the phenomenon of the workpiece shifting during processing.
