When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be another intermediate component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be another intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] Figure 1-Figure 8 The utility model discloses a tool magazine automatic door protection structure, which comprises a tool magazine door frame 10 , a tool magazine door 20 , a cylinder 30 , a guide rail 40 , a guide wheel 50 , a pressure plate 60 and a connecting plate 70 .

[0031] In this embodiment:

[0032] The tool magazine door frame 10 includes a first frame 11 and a second frame 12. An obtuse angle is formed between the first frame 11 and the second frame 12, and an opening 13 is formed between the two. The tool magazine door frame 10 is also provided with an edge seal 14. The edge seal 14 faces the inside of the opening 13, and an obtuse angle is formed between the edge seal 14 and the tool magazine door frame 10. The edge seal 14 is specifically designed as a rubber scraper, and is used to contact and seal with the tool magazine door 20. In this embodiment, the edge seal 14 is arranged on the upper and lower edges and the side edges of the opening 13. There are two edge seals 14 on the side edges. One side edge edge seal 14 is arranged on the first frame 11, and one side edge seal 14 is arranged on the second frame 12. An obtuse angle is formed between the two side edge seals 14.

[0033] A folding edge 21 is provided on one side of the tool magazine door 20, and the length direction of the folding edge 21 is perpendicular to the length direction of the edge seal 14. The folding edge 21 faces the inside of the opening 13 and the outer surface of the folding edge 21 contacts the edge seal 14, so that during the sliding process of the tool magazine door 20, the tool magazine door 20 is always fitted and sealed with the edge seal 14. If the folding edge 21 is set to face the outside of the opening 13, the gap between the tool magazine door 20 and the edge seal 14 is increased, and the folding edge 21 may collide with the connecting plate 70, and cannot play a sealing and chip prevention role, but affects the opening and closing of the tool magazine door 20. In this embodiment, the tool magazine door 20 adopts a bending structure, and the tool magazine door 20 matches the shape of the opening 13. The folding edge 21 is a U-shaped structure, which can make it better fit and seal with the tool magazine door 20, and will not damage the edge seal 14, and can effectively prevent chips and chip liquid from entering the tool magazine area, and the protection performance is better.

[0034] The cylinder 30 is arranged inside the opening 13 and is in transmission connection with the tool magazine door 20. The cylinder 30 drives the tool magazine door 20 to slide on the tool magazine door frame 10, thereby realizing the opening and closing of the tool magazine door 20. When the tool magazine door 20 is in an open state, the tool magazine door 20 is located on one side of the opening 13; when the tool magazine door 20 is in a closed state, the tool magazine door 20 covers the opening 13. In this embodiment, the cylinder 30 is a rodless cylinder 30.

[0035] Two guide rails 40 are arranged on the inner side of the opening 13 , and the two guide rails 40 are installed on the tool magazine door frame 10 and are located on the upper and lower sides of the tool magazine door 20 . The cylinder 30 drives the tool magazine door 20 to move along the length direction of the guide rails 40 , thereby realizing the opening and closing of the tool magazine door 20 .

[0036] Multiple guide wheels 50 and two pressure plates 60 are arranged inside the opening 13. Multiple guide wheels 50 are installed on the tool magazine door 20 and are distributed at both ends of the tool magazine door 20. Two pressure plates 60 are installed on the tool magazine door frame 10 and are located on the upper and lower sides of the tool magazine door 20. The pressure plates 60 clamp the guide wheels 50 so that the guide wheels 50 constrain the tool magazine door 20 in the upper and lower directions when the upper and lower pressure plates 60 are clamped. In this embodiment, the number of guide wheels 50 is 6, and three guide wheels 50 are respectively installed at both ends of the tool magazine door 20. In this embodiment, the guide wheels 50 are made of silent material, specifically POM, which has the characteristics of silence and self-lubrication, so that the tool magazine door 20 can move in a stable and low-noise state.

[0037] The connecting plate 70 is disposed at the opening 13 and is located outside the tool magazine door 20 . The upper and lower ends of the connecting plate 70 are fixedly connected to the edge sealing 14 , respectively.

[0038] In the present application, a sealing edge sealing structure 14 is provided at the edge of the opening 13 of the tool magazine door frame 10, and a U-shaped folded edge 21 structure is provided on one side of the tool magazine door 20. This not only allows the edge sealing 14 to be completely fitted with the folded edge 21 of the tool magazine door 20 during the sliding process of the tool magazine door 20, thereby achieving high stability in opening and closing the door, but also does not damage the edge sealing 14, thereby extending its service life, and can effectively prevent chips and chip liquid from entering the tool magazine area, thereby providing better protective performance. The present application also provides guide wheels 50 at the upper and lower boundaries of the tool magazine door 20, and adopts a silent design, thereby ensuring transmission stability while reducing noise during movement.

[0039] The present application also relates to a machine tool comprising the above-mentioned tool magazine automatic door protection structure.

[0040] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
