Description

Technical Field

[0001] This utility model relates to the field of laser marking fixture technology, specifically a multi-workpiece parallel laser marking fixture. Background Technology

[0002] Multi-workpiece parallel fixtures are fixture systems capable of simultaneously clamping multiple workpieces and enabling parallel machining. They are commonly used in high-precision, high-efficiency machining scenarios. Their core feature is the use of modular design or virtual axis structures to achieve synchronous positioning and clamping at multiple stations, allowing for the simultaneous fixing of multiple workpieces. This makes them suitable for the parallel machining of batches or complex parts.

[0003] An adjustable multi-workpiece positioning fixture, as disclosed in authorization announcement number CN219484908U, includes a positioning base. The upper surface of the positioning base is provided with a plurality of first positioning grooves and second positioning grooves for placing workpieces. The positioning base is movably provided with a plurality of clamping mechanisms corresponding to the first positioning grooves and second positioning grooves on both sides along the length direction. The clamping mechanism includes a clamping rod and a clamping cylinder for pressing the workpiece in the vertical or horizontal direction. An angle adjustment component is fixedly connected to one side of the positioning base in the width direction.

[0004] Although it achieves the setting of first and second positioning slots of different sizes, it can be adapted to the auxiliary positioning of aluminum profile workpieces of different sizes. It makes reasonable use of space, realizes multi-station setting in a limited space, and realizes the synchronous auxiliary positioning and processing of multiple workpieces. When changing workpieces of different sizes, only the position of the clamping mechanism needs to be adjusted locally, which improves production efficiency, reduces production costs, and is highly practical.

[0005] However, this does not solve the problem that existing laser marking fixtures of this type are generally not conducive to convenient parallel clamping and fixing of multiple workpieces, making it inconvenient to mark multiple workpieces at once, affecting the time for loading and unloading workpieces, and making it inconvenient to adjust the workpiece clamping position in multiple stages, thus affecting the clamping range of the workpieces.
