[0013] Figure 2 The utility model is an exploded view of an automatic door tool magazine guard applied to a CNC milling machine. DETAILED DESCRIPTION

[0014] The following will clearly and completely describe the technical solutions in the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present utility model.

[0015] like Figure 1 to Figure 2 As shown, an automatic door tool magazine guard applied to a CNC milling machine comprises a tool magazine door 1 connected to the CNC milling machine, the tool magazine door 1 is provided with a tool changing port 2, the tool magazine door 1 is slidably matched with an accordion-type protective cover 3, the accordion-type protective cover 3 covers the tool changing port 2, the tool magazine door 1 is provided with a mechanically coupled rodless cylinder 4 that drives the accordion-type protective cover 3 to fold and unfold horizontally so as to realize the opening and closing of the tool magazine door 1, the mechanically coupled rodless cylinder 4 is horizontally installed on the upper plane of the tool magazine door 1, the mechanically coupled rodless cylinder 4 is installed with a connecting block 5, and a movable plate 6 is fixedly provided on the connecting block 5. The utility model provides a tool magazine guard with an automatic door on the CNC milling machine, and the setting of the accordion-type protective cover 3 can meet the need of replacing tools when opened, and can effectively prevent chips, water mist, dust, oil mist, etc. generated by processing from entering the tool magazine area to pollute and damage the tool magazine when closed, thereby ensuring the service life of the tool magazine and the tool.

[0016] The movable plate 6 is vertically fixed on one side of the accordion-type protective cover 3, and is connected to the connecting block 5 to drive the accordion-type protective cover 3 to fold and unfold horizontally. The movable plate 6 is composed of a right-angle plate 61 and a connecting plate 62. One right-angle side of the right-angle plate 61 is fixed to the accordion-type protective cover 3, and the other right-angle side is against the accordion-type protective cover 3. The connecting plate 62 is fixed on an end face of the right-angle plate 61 close to the mechanically coupled rodless cylinder 4, and is fixedly connected to the connecting block 5. The movable plate 6 and the tool magazine door 1 are slidably matched through a sliding assembly. The sliding assembly includes a slide rail 7 and a slider 8 adapted to the slide rail 7. The slide rail 7 is laterally symmetrically arranged on the upper and lower sides of the tool changing port 2, and the slider 8 is arranged on the movable plate 6 relative to the slide rail 7.

[0017] The movable plate 6 is made of metal and is fixedly connected to the accordion-type protective cover 3.

The setting of the guide strip 9 enables the accordion-type protective cover 3 to cover the tool changing port 2 and move in a specific direction to open and close the tool changing port 2, thereby facilitating the automatic tool changing system to automatically replace the tool.

[0019] A side plate 10 is vertically arranged on one side edge of the knife changing port 2 , and the side plate 10 is fixedly connected to one end of the accordion-type protective cover 3 away from the movable plate 6 . The setting of the side plate 10 limits the movement distance of the accordion-type protective cover 3 .

[0020] From the above description of the utility model, it can be seen that compared with the prior art, the utility model provides an automatic door tool magazine guard applied to a CNC milling machine, in which a mechanically coupled rodless cylinder 4 is connected to a movable plate 6 through a connecting block 5, thereby driving the movable plate 6 to move left and right, and the movable plate 6 drives the accordion-type protective cover 3 to shrink or expand, and can automatically control the opening or closing of the tool change port 2. When a collision occurs, the movable movable plate 6 will first contact the colliding structure to achieve the purpose of protecting the accordion-type protective cover 3. The setting of the accordion-type protective cover 3 facilitates the automatic replacement of the tool by the automatic tool changing system when it is opened, and effectively prevents the chips, water mist, dust, oil mist, etc. generated by the processing from entering the tool magazine area to pollute and damage the tool magazine, thereby ensuring the service life of the tool magazine and the tool.

[0021] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
