Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to an adjustable galvanometer cavity fixture fixing head. Background Technology

[0002] In the manufacturing field, machine tools (such as conventional lathes, conventional milling machines, CNC lathes, CNC milling machines, machining centers, etc.), laser engraving machines, engraving machines, and printing machines require products to be clamped and fixed before processing. Composite machining is one of the most popular machining processes internationally, representing an advanced manufacturing technology. Composite machining combines several different processing techniques on a single machine tool. The most widely used and most challenging type of composite machining is mill-turn machining. A mill-turn machining center is essentially a combination of a CNC lathe and a machining center.

[0003] However, in actual production and processing, we found that in the first application 202220741776.9, the second clamping head of the three-piece jig disclosed by the applicant is used to position the galvanometer cavity for processing. Since the two are directly mounted separately and there are no other auxiliary positioning structures, the galvanometer cavity shakes during processing. If a shim is added to the inner wall of the galvanometer cavity to make the two interfere with each other, it will be inconvenient to adjust the position. Therefore, we improved the original device and proposed a new adjustable device that can position the galvanometer cavity to meet production needs. Utility Model Content
