Description

Technical Field

[0001] The utility model relates to the technical field of pallets, in particular to a pallet exchange device for a vertical machining center. Background Art

[0002] A vertical machining center is a vertical lathe. The difference between a vertical machining center and an ordinary lathe is that its spindle is vertical, which is equivalent to standing an ordinary lathe upright. Since its workbench is in a horizontal position, it is suitable for processing heavy parts with large diameters and short lengths. A tray is installed on the top of the vertical machining center to facilitate the fixing of the workpiece to be processed.

[0003] In order to ensure that the parts to be processed do not shake when entering the processing area and being processed, the parts to be processed in the pallet need to be fixed. Common fixing structures mostly use a driver to directly push the clamping plate to fix the parts. This method easily occupies part of the pallet space, thereby reducing the clamping range. Therefore, those skilled in the art provide a pallet exchange device for a vertical machining center to solve the problems raised in the above background technology. Utility Model Content
