Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figures 1-5The diagram shown illustrates the structure of a novel precision quick-change tool according to an embodiment of this utility model. It includes a tool-side fixture 1, a piston cylinder 6, a steel ball positioning ring 2, and a cutting mandrel 4. The piston cylinder 6 is mounted on the bottom of the tool-side fixture 1. Data transmission modules are also arranged on the tool-side fixture 1 and the piston cylinder 6. These data transmission modules include a data transmission module A11 and a data transmission module B12. The data transmission module A11 is fixedly mounted on the side of the tool-side fixture 1, and the data transmission module B12 is fixedly mounted on the same side of the piston cylinder 6. The steel ball positioning ring 2 is arranged inside the tool-side fixture 1, and multiple steel balls 9 are mounted on it. The cutting mandrel 4 is coaxially arranged within the steel ball positioning ring 2 and connected by a guide member 3. The guide member 3 axially positions the cutting mandrel 4, allowing it to move only a limited distance up and down, generating a locking force. A disc spring 8 is arranged at the bottom of the cutting mandrel 4, and the disc spring 8 is mounted inside the piston cylinder 6. The piston cylinder 6 and the steel ball positioning ring 2 are locked together by screws.

[0027] In one embodiment of this utility model, a sensor 7 is installed at the bottom of the piston cylinder 6, and a positioning pin 10 is installed at the top of the tool-side fixture 1.

[0028] like Figure 2 As shown, in a preferred embodiment of the present invention, a sealing ring 5 is arranged between the cutting mandrel 4 and the inner wall of the piston cylinder 6.

[0029] In one embodiment of this utility model, by arranging the sealing ring 5, the sealing performance of the tool during use can be improved when the cutting mandrel 4 moves.

[0030] In summary, when the piston on the cutting tool spindle 4 is vented, it generates an upward pushing force. This force overcomes the preload of the disc spring 8, causing the steel ball 9 to retract into the steel ball positioning ring 2. The tool-side fixture 1 is then released, allowing other tool-side fixtures to be replaced.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
