Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a galvanometer cavity clamping fixture with a quick-release structure. 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 the actual production and processing process, we found that the three-piece jig disclosed in the applicant's prior application 202220741776.9 requires the use of tools to remove the fixing screws of the support base before the galvanometer cavity can be removed after the processing is completed. This greatly prolongs the loading and unloading time. Therefore, we improved the original device and proposed a new jig to meet the production needs. Utility Model Content

A transition plate 50 is coaxially mounted at the front end of the rotating spindle 40, and a positioning mold head 60 for the positioning galvanometer cavity 200 is mounted on the front side wall of the transition plate 50; a positioning hole 401 is coaxially extending through the front end of the rotating spindle 40, and a screw shaft 70 is coaxially rotatably mounted in the positioning hole 401. The screw shaft 70 is connected to the adapter plate 50 at one end, and the outer cylinder 80 is coaxially threaded to the rear end of the screw shaft 70. The outer cylinder 80 is rotatably connected to the support base 20 through the bearing assembly 90. The rear side of the support base 20 is provided with a turntable 100 that is coaxially fixed with the outer cylinder 80. In use, the screw shaft 70 is driven to move forward or backward through the turntable 100, thereby adjusting the front and rear positions of the positioning mold head 60, thereby quickly adjusting the distance between the positioning mold head 60 and the bonding head 10, which greatly facilitates the rapid unloading and loading of the galvanometer cavity 200 and further improves the processing efficiency.

[0027] In this embodiment, a groove 402 is coaxially provided on the front end face of the rotating spindle 40, and a slider 110 adapted to it is provided in the groove 402. The front end of the screw shaft 70 passes through the slider 110 and is threadedly connected to the adapter plate 50. The slider 110 and the groove 402 are both circular. Through the cooperation of the slider 110 and the groove 402, the front end of the screw shaft 70 can be guided and positioned to ensure the coaxiality of the screw shaft 70.

[0028] In this embodiment, a guide shaft 120 is provided through the front end face of the adapter plate 50 facing rearward. A guide groove 403 adapted to the guide shaft 120 is provided on the front end face of the rotating spindle 40. The guide shaft 120 is detachably connected to the adapter plate 50. Specifically, the guide shaft 120 is threadedly connected to the adapter plate 50.

The mounting seat 140 is detachably connected to the rotating spindle 40 by fixing bolts to facilitate installation and disassembly, and to facilitate the replacement of the inner rotating bearings 91.

[0032] In this embodiment, a positioning bolt 160 is vertically provided on the top of the support base 20. The lower end of the positioning bolt 160 passes through the mounting hole 201. A positioning groove 406 is provided on the side wall of the rotating spindle 40 corresponding to the positioning bolt 160. There are multiple positioning grooves 406 and they are evenly distributed circumferentially. By tightening the positioning bolt 160 downward and pressing it against the positioning groove 406, the rotating spindle 40 can be prevented from rotating, which facilitates the maintenance or replacement of the positioning mold head and the internal bearing components.
