Description

Technical Field

[0001] The utility model relates to the technical field of gantry milling machine protection, in particular to a protection mechanism for a gantry milling machine. Background Art

[0002] A gantry milling machine is a milling machine with a portal frame and a horizontal long bed. Multiple milling cutters can be used to process surfaces simultaneously on a gantry milling machine. The processing accuracy and production efficiency are relatively high. It is suitable for processing planes and inclined surfaces of large workpieces in batch and mass production.

[0003] In the prior art, a Chinese patent with announcement number CN219465594U discloses an outer protective cover for a gantry milling machine that is easy to use, which adopts the scheme of "including a fixed slide rail, a first baffle is arranged on the left side of the top of the fixed slide rail, a second baffle is arranged on the right side of the top of the fixed slide rail, rollers are arranged on the left and right sides of the bottom of the first baffle and the second baffle, a second groove is arranged on the side away from the front end of the first baffle and the second baffle on the rear side, and a slide groove is arranged on the side away from the first baffle and the second baffle on the front side". In the utility model, the fixed slide rail is fixed to the bottom of the gantry milling machine, and the first baffle and the second baffle are placed on the top of the fixed slide rail by the roller, and the hook is hooked on the ring to fix the first baffle, and then the first baffle and the second baffle are fixed by the fixing bolt, and the rear end of the side baffle passes through the slide groove and is placed in the second groove, which is convenient and quick to operate.

[0004] However, the above scheme still has some shortcomings. For example, after the above scheme is fixedly installed with the milling machine, when the milling machine needs to be fed, the side baffle plate needs to be separately pulled out from the two first baffle plates. Without the restriction of the side baffle plate, the first baffle plate is slid to expose the milling machine. When the loading is completed, the side baffle plate needs to be reinserted between the two first baffle plates for installation to complete the assembly work. This opening method is too cumbersome and affects the feeding speed of the milling machine. In view of this, the utility model proposes a protective mechanism for a gantry milling machine.
