Description

Technical Field

[0001] The utility model belongs to the technical field of milling machines, in particular to a protective cover for a milling machine. Background Art

[0002] A milling machine is a machine tool used for milling, drilling and boring workpieces. The main feature of a milling machine is that it uses a milling cutter as a cutting tool to process a variety of surfaces on the workpiece. When working, the milling cutter mainly rotates, and the movement of the workpiece and the milling cutter is the feed motion. This machine tool can process planes, grooves, gears, threads and spline shafts, etc. Milling machines are suitable for a variety of materials, including metals, plastics, wood, etc., so they are widely used in machinery manufacturing, automobile manufacturing, aerospace and shipbuilding, etc. In order to isolate the processing process, current milling machines usually have protective covers on them to protect them.

[0003] The utility model patent with patent application publication number 202223217318.4 discloses a protective cover for a milling machine, which comprises a protective cover, one side of the protective cover is rotatably connected to a top cover via a rotating shaft, a collecting assembly is provided at the bottom of the protective cover, through grooves are provided on both sides of the protective cover, a box body is provided at the bottom of the collecting assembly, and the collecting assembly comprises a collecting box provided at the bottom of the protective cover. The protective cover for a milling machine provided by the utility model solves the problem that in actual use of the existing protective cover for a milling machine, when a workpiece is milled in the protective cover, the iron filings generated will remain inside the protective cover, and the staff needs to clean it regularly, which is inconvenient to use and has low practicality.

[0004] However, the above device still has shortcomings in actual use. The most obvious one is that the threaded rod is rotated to drive the threaded block, connecting rod and movable ring to move, so as to remove the iron filings adsorbed on the outside of the magnetic column. However, the iron filings are easy to fall into the gap on the threaded rod during the removal or falling process, so that the threaded rod cannot drive the threaded block to move normally, thereby reducing the collection efficiency of iron filings during the operation of the milling machine. For this reason, we propose a milling machine protective cover. Utility Model Content
