Description

Technical Field

[0001] This utility model belongs to the field of gantry machining technology, and more specifically, it relates to a quick-locking and positioning structure for the column of a gantry machining center. Background Technology

[0002] Currently, in the operation of gantry machining centers, the positioning and locking of the columns are key factors in ensuring machining accuracy. Traditional column positioning structures have many problems. First, in terms of clamping, the clamping methods are not flexible enough. Most can only perform a single clamping method, either independent clamping or combined clamping, but cannot effectively balance both. This necessitates changing different clamping devices to meet different machining requirements, greatly reducing machining efficiency.

[0003] Secondly, existing column structures lack effective storage space, making it difficult to place auxiliary tools or small parts to be processed during the machining process. Furthermore, the machining process generates a large amount of dust, and traditional column structures often lack integrated dust extraction capabilities. The presence of dust not only affects the machining environment but may also cause workpiece clamping issues due to the generated iron filings and dust. Utility Model Content
