[0035] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0036] like Figures 1 to 11 As shown, a CNC tool storage rack includes a bracket 1, on which a tool storage device 2 is installed. The number of the tool storage devices 2 can be one or more. When multiple tool storage devices 2 are provided, they are arranged in sequence from top to bottom.

[0037] like Figure 2 As shown, the tool storage device 2 includes a fixed roller 6 , a rotating sleeve 3 and a tool storage 4 .

[0038] The roller shafts 6.3 at both ends of the fixed roller 6 are fixedly mounted on the bracket 1 through the fixing seats 8, so the fixed roller 6 is stationary.

[0039] The rotating sleeve 3 is a hollow cylindrical structure, which is sleeved on the fixed roller 6 and rotated around its axis. Specifically, end caps 7 are installed at both ends of the rotating sleeve 3 by screws, and the end caps 7 are rotatably connected to the roller shaft 6.3 on the same side by bearings. Therefore, the rotating sleeve 3 can rotate relative to the fixed roller 6.

[0040] There are 6-8 groups of storage grooves 3.1 evenly arranged along the circumference of the rotating sleeve 3, each group of storage grooves 3.1 has no less than 8 and are distributed in a straight line parallel to the central axis. It can be seen that the rotating sleeve 3 can store at least 48 tools 5, which significantly improves the storage capacity.

[0041] The tool receivers 4 are stored in the storage slots 3.1 one by one. The tool receivers 4 are stored in each group of storage slots 3.1 according to the type of the tool 5, that is, the same type of tools 5 are stored in the same group of storage slots 3.1 according to different specifications, so that users can choose suitable tools 5 in a targeted manner. A label recording the type and specification information of the tool 5 can be attached to the outer end of the tool receiver 4. Since the rotating sleeve 3 is set to rotate, in order to prevent the inverted tool receiver 4 from detaching from the storage slot 3.1 and enable the user to normally take and put the tool receiver 4, the inner end of the tool receiver 4 is configured to be connected to the fixed roller 6 through a connecting structure.

[0042] When any group of tool storage devices 4 rotates to a specific position along with the rotating sleeve 3, the connection structure between the group of tool storage devices 4 and the fixed roller 6 is in a released state. At this time, the group of tool storage devices 4 can be taken and placed normally, while the connection structure between the remaining groups of tool storage devices 4 and the fixed roller 6 is in a connected state and will not fall due to inversion.

[0043] like Figure 4 and 5As shown, the connection structure is realized by the following means: the roller surface 6.5 of the fixed roller 6 is provided with annular grooves 6.1 of the same number as the number of groups of receiving grooves 3.1 and a socket 6.2 penetrating the annular grooves 6.1. The annular groove 6.1 has a limit groove 6.1a located on the roller surface 6.5 and a matching groove 6.1b located inside the roller surface 6.5. Correspondingly, the inner end of the tool storage 4 is provided with a matching portion 4.3, and the matching portion 4.3 has a connecting section 4.3a located at the inner end of the tool storage 4 and a spherical portion 4.3b located at the end of the connecting section 4.3a; the size relationship between the connecting section 4.3a, the limit groove 6.1a, the spherical portion 4.3b and the socket 6.2 is:

[0044] R 1 <W 1 <W 2 <R 2 <R 3 , R 1 is the diameter of the connecting section 4.3a, W 1 is the width of the limit slot 6.1a, W 2 To match the width of slot 6.1b, R 2 is the diameter of the spherical portion 4.3b, R 3 The diameter of the socket is 6.2.

[0045] As the rotating sleeve 3 rotates, when it reaches a specific position, the spherical parts 4.3b of a group of tool receivers 4 are aligned with the insertion holes 6.2. Since the diameter of the insertion holes 6.2 is larger than the diameter of the spherical parts 4.3b, the tool receivers 4 at this position can be taken out normally, so that the user can take out the tools 5. As the rotating sleeve 3 rotates, when it leaves the specific position, the spherical parts 3.2b of all tool receivers 4 slide in the matching grooves 6.1b, and cannot be separated from the matching grooves 6.1b under the obstruction of the limiting grooves 6.1a, thereby achieving the fixation of the tool receivers 4 in the storage grooves 3.1.

[0046] When in use, the specific angle of a specific position can be set according to the height of the tool storage device 2 and the user's usage habits, for example, the angle between the central axis of the insertion hole 6.2 and the horizontal plane is 45 degrees. In this way, the tool storage device 4 after reaching the specific position is taken out and put back by the user in a manner of tilting 45 degrees.

[0047] In order to enable the user to accurately rotate the rotating sleeve 3 to a specific position, a positioning assembly is provided between the fixed roller 6 and the rotating sleeve 3. When the rotating sleeve 3 is at a specific position, the fixed roller 6 and the rotating sleeve 3 are positioned by the positioning assembly.

[0048] Specifically, Figure 6 and 7As shown, the roller surface 6.5 of the fixed roller 6 is provided with a mounting hole 6.4, and the inner wall of the rotating sleeve 3 is provided with a positioning groove 3.2 that can cooperate with the positioning assembly. The number of positioning grooves 3.2 is equal to the number of groups of receiving grooves 3.1. The positioning assembly includes a positioning pin 9 and an ejection spring 10. When the rotating sleeve 3 rotates to a specific position, the positioning pin 9 cooperates with one of the positioning grooves 3.2 under the action of the ejection spring 10, which will cause the rotating sleeve 3 to generate a resistance, so that the user can detect that the rotation is in place at this time. To continue rotating, it is only necessary to increase the rotational force so that the positioning pin 9 overcomes the elastic force of the ejection spring 10 and retracts inward.

[0049] As a preferred example, the tool storage 4 is a cylindrical structure, which includes a storage body 4.1 and a sealing cover 4.2 detachably mounted at an opening of the storage body 4.1. The sealing cover 4.2 is threadedly connected to the opening of the storage body 4.1. Since most of the storage body 4.1 is stored in the storage groove 3.1, the exposed part is small, so that the tool 5 is sealed and stored, and the sealing cover 4.2 cannot be opened without taking out the tool storage 4.

[0050] As a preferred example, the inner end of the storage groove 3.1 is provided with a step structure 3.1a for limiting the storage depth of the tool storage 4. When the tool storage 4 is placed in the storage groove 3.1, it only needs to be inserted to the bottom, and then the matching portion 4.3 can slide into the annular groove 6.1 by rotating the rotating sleeve 3.

[0051] As a preferred example, a plurality of shelves 1.1 are arranged from top to bottom on the bracket 1 below the tool storage device 2. The shelves 1.1 can be used to place other machine tool accessories to improve the storage capacity.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
