In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0030] The embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0031] Figure 1 Front view of the CNC tool storage device in the embodiment. Figure 2 For Figure 1A-A direction sectional view. Figure 3 A schematic diagram of three-dimensional structure of the CNC tool storage device in the embodiment. Figure 4 A schematic diagram of exploded structure of the CNC tool storage device in the embodiment. As shown in Figures 1-4 The CNC tool storage device includes a protective cylinder 100. The protective cylinder 100 has a hollow sandwich 110 in a cylindrical shape. An oil injection port 120 is formed on the outer side wall of the protective cylinder 100, and a plug (not shown in the figure) is matched with the oil injection port 120. Through the oil injection port 120, an appropriate amount of lubricating oil can be injected into the hollow sandwich 110 to protect the stored CNC tools. A plurality of oil leakage holes 130 are formed on the inner bottom of the protective cylinder 100. Through the oil leakage holes 130, the excess lubricating oil on the inner side of the protective cylinder 100 can be guided into the hollow sandwich 110.

[0032] As shown in Figure 2 and Figure 3 The CNC tool storage device further includes a buffer sponge pad 200. The buffer sponge pad 200 is matched and laid on the inner bottom of the protective cylinder 100, and is used to provide appropriate buffering for the CNC tools placed in the protective cylinder 100 to avoid damage. At the same time, at least one oil absorption foot 210 is formed on the side of the buffer sponge pad 200 facing the oil leakage hole 130. The oil absorption foot 210 is made of the same material as the buffer sponge pad 200. The oil absorption foot 210 penetrates through the corresponding oil leakage hole 130 and extends into the hollow sandwich 110. The porous characteristics of the material of the buffer sponge pad 200 can make the lubricating oil in the hollow sandwich 110 automatically and gradually transfer to the entire buffer sponge pad 200 along the oil absorption foot 210.

[0033] As shown in Figures 2-4 The CNC tool storage device further includes an oil coating assembly 300. The oil coating assembly 300 is matched and arranged in the protective cylinder 100, and is used to coat and protect the surface of the CNC tools placed in the protective cylinder 100. The oil coating assembly 300 includes a sponge oil coating ring 310 and one or more pull rods 320. For example, Figure 3 three pull rods 320 are arranged as shown in the figure. The sponge oil coating ring 310 is matched and arranged on the inner side of the protective cylinder 100. In the natural state, the inner diameter of the sponge oil coating ring 310 is smaller than the diameter of the corresponding CNC tool. At the same time, when the sponge oil coating ring 310 is in contact with the buffer sponge pad 200, the lubricating oil can be transferred from the buffer sponge pad 200 to the sponge oil coating ring 310. One end of the pull rod 320 is connected with the sponge oil coating ring 310, and the other end extends to the outer side of the protective cylinder 100.

[0034] When the CNC tool needs to be stored in this embodiment, the CNC tool is directly placed in the protection cylinder 100 and passes through the sponge oiling ring 310; the user manually holds and pulls the pull rod 320 to drive the sponge oiling ring 310 to slide back and forth along the length direction of the CNC tool, so that the lubricating oil transferred from the buffer sponge pad 200 to the sponge oiling ring 310 can be applied to the surface of the CNC tool; after the CNC tool oiling protection is completed, the CNC tool storage device can be vertically or horizontally placed for temporary storage together with the CNC tool.

[0035] Compared with the existing CNC tool protection sleeve structure, the CNC tool storage device in this embodiment does not use rubber fixation, and the CNC tool insertion process is not affected; at the same time, the CNC tool does not directly use the immersion lubricating oil method for protection, but uses the sponge surface smearing method, which can save lubricating oil and avoid the leakage problem caused by excessive sponge adsorption of lubricating oil; furthermore, when the protection cylinder is horizontally placed, the lubricating oil can be collected in the annular cavity area of the hollow layer, avoiding oil leakage.

[0036] Further, as shown in Figures 2-4 The oiling assembly 300 further includes a guide sleeve 330. The guide sleeve 330 is embeddedly matched in the inner side of the open end of the protection cylinder 100; the center of the guide sleeve 330 is a through tool inlet 331; the CNC tool is inserted into the protection cylinder 100 from the tool inlet 331, and the main part of the CNC tool is located between the guide sleeve 330 and the bottom of the protection cylinder 100, with a certain gap between its outer wall and the inner wall of the protection cylinder 100, facilitating the movement of the sponge oiling ring; the remaining small part of the CNC tool is located outside the tool inlet 331, facilitating the holding; a guide hole 332 is further provided on the guide sleeve 330 in a direction parallel to the axial center of the protection cylinder 100, which can be passed through by the pull rod 320; when the sponge oiling ring 310 contacts the buffer sponge pad 200, the free end of the pull rod 320 is located outside the guide hole 332 and is higher than the end of the CNC tool located outside the tool inlet 331. Through the arrangement of the guide sleeve, a gap is formed between the CNC tool and the protection cylinder after the CNC tool is placed, which is beneficial to the movement of the sponge oiling ring; at the same time, the guide sleeve can also provide support for the movement of the pull rod and limit the movement of the sponge oiling ring from the guide sleeve.

[0037] Further, an annular step 140 is arranged on the inner wall of the open end of the protection cylinder 100, and the guide sleeve 330 abuts against the annular step 140, thereby limiting the position of the guide sleeve 330 embedded in the open end of the protection cylinder 100.

[0038] Further, as shown in Figures 2-4As shown in the figure, the oil coating assembly 300 further comprises a squeezing ring plate 340. The squeezing ring plate 340 is arranged on the side of the sponge oil coating ring 310 away from the oil leakage hole 130, and the inner diameter of the squeezing ring plate 340 is larger than that of the sponge oil coating ring 310; the pulling rod 320 is connected with the squeezing ring plate 340. In this embodiment, a certain pressure can be applied to the squeezing ring plate through the pulling rod, and the sponge oil coating ring and the buffer sponge pad are further squeezed by the squeezing ring plate, so that the excess lubricating oil adsorbed on the sponge oil coating ring and the buffer sponge pad is squeezed out and enters the hollow layer through the oil leakage hole.

[0039] Further, as shown in the figure, the CNC tool storage device further comprises a protective cover 400. The protective cover 400 is fitted and clamped outside the open end of the protective cylinder 100, and when the protective cover 400 is pressed and moved towards the bottom of the protective cylinder 100, the inner side of the protective cover 400 gradually abuts against the free end of the pulling rod 320 and pushes the squeezing ring plate 340 to squeeze the sponge oil coating ring 310 and the buffer sponge pad 200, thereby realizing the control of the oil absorption amount of the sponge oil coating ring 310 and the buffer sponge pad 200 each time the protective cover 400 is closed. Figures 1-4 Further, as shown in the figure, the CNC tool storage device further comprises a protective cover 400. The protective cover 400 is fitted and clamped outside the open end of the protective cylinder 100, and when the protective cover 400 is pressed and moved towards the bottom of the protective cylinder 100, the inner side of the protective cover 400 gradually abuts against the free end of the pulling rod 320 and pushes the squeezing ring plate 340 to squeeze the sponge oil coating ring 310 and the buffer sponge pad 200, thereby realizing the control of the oil absorption amount of the sponge oil coating ring 310 and the buffer sponge pad 200 each time the protective cover 400 is closed.
