[0029] 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.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5 The present invention provides an automatic tool changing device for a CNC machine tool for watch case processing, comprising: a CNC machine tool body 1, an automatic tool changing device body 4 mounted on one side of the CNC machine tool body 1, an adjustment device 2 provided on one side of the automatic tool changing device body 4, and an auxiliary device 3 provided at one end of the automatic tool changing device body 4.

[0032] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The adjusting device 2 includes two fixed rods 21, both of which are fixedly connected to one side of the automatic tool changer body 4. A common connecting plate 22 is fixedly connected to one end of the arc-shaped surfaces of the two fixed rods 21 that are close to each other. A rotating ring 23 is rotatably connected to the arc-shaped surface of the connecting plate 22. A connecting rod 24 is fixedly connected to one end of the arc-shaped surface of the rotating ring 23. A protective plate 25 is fixedly connected to one end of the arc-shaped surface of the connecting rod 24. A connecting plate 26 is fixedly connected to one side of the connecting plate 22. A rotating rod 27 is threaded through the inner wall of the connecting plate 26. The casing is then... The automatic tool changer body 4 of the CNC machine tool body 1 is commonly referred to as the automatic tool changing system. Its main function is to automatically change tools, enabling efficient and precise completion of various processing requirements without manual intervention. However, the tool heads on the automatic tool changer body 4 may break after prolonged use, and these broken pieces can scatter, posing a safety hazard to nearby workers. In such cases, the machining position of the automatic tool changer body 4 and the CNC machine tool body 1 can be adjusted using the adjusting device 2. To prevent the blade fragments from breaking and endangering workers in the event of a breakage of the automatic tool changer body 4, a stop block 29 is fixedly connected to one end of the arc surface of the rotating rod 27. The stop block 29 has a circular cross-section. When the rotating rod 27 contacts the rotating ring 23, the stop block 29 on the rotating rod 27 improves the stability of the contact between the rotating rod 27 and the rotating ring 23, thereby improving the stability of limiting the rotation ring 23. Several anti-slip grooves are provided at the other end of the arc surface of the rotating rod 27. 28. Several anti-slip grooves 28 are evenly distributed on the rotating rod 27. When the rotating rod 27 is rotated on the connecting plate 26, the anti-slip grooves 28 on the rotating rod 27 can increase the friction on the surface of the rotating rod 27. Thus, the stability of rotating the rotating rod 27 on the connecting plate 26 can be improved by the anti-slip grooves 28. The protective plate 25 is an acrylic plate. When the protective plate 25 protects the entire working area of ​​the watch case processing, the acrylic protective plate 25 makes it easy for the user to check the processing effect of the watch case and improves the stability of the watch case processing.

[0033] In the embodiments of this utility model, please refer to Figure 5The auxiliary device 3 includes a fixed frame 31, which is fixedly connected to one end of the automatic tool changer body 4. A connecting rod 32 is fixedly connected to one inner wall of the fixed frame 31. A baffle 34 is rotatably connected to the arc surface of the connecting rod 32. A coil spring 33 is slidably connected to both ends of the arc surface of the connecting rod 32. The two ends of the coil spring 33 are fixedly connected to the baffle 34 and the side wall of the fixed frame 31, respectively. A cleaning brush 35 is slidably connected to the other inner wall of the fixed frame 31. When the watch case is processed by the automatic tool changer body 4 and the CNC machine tool body 1, the auxiliary device can be used to process the watch case. 3. The cleaning device 3 cleans the debris generated during processing, thereby improving the cleanliness of the entire processing environment. The surface of the cleaning brush 35 is fixedly connected to the anti-slip sleeve 37, and the side of the anti-slip sleeve 37 is provided with anti-slip texture. When the cleaning plate is used to clean the debris generated during the processing of the CNC machine tool body 1, the anti-slip sleeve 37 installed on the cleaning plate can increase the friction of the cleaning plate surface, thereby improving the stability of the user when using the cleaning plate for cleaning tasks. An arc-shaped block 36 is fixedly connected to one side of the baffle 34, and the cross-section of the arc-shaped block 36 is arc-shaped.

[0034] The effect achieved by the above components is that when it is necessary to pull the baffle 34, the baffle 34 can be pulled by the arc-shaped block 36 installed on the baffle 34. The efficiency and speed of pulling the baffle 34 can be improved by the arc-shaped block 36.

[0035] The working principle of the automatic tool changer for a CNC machine tool used for watch case processing provided by this utility model is as follows: Rotating the rotating ring 23 on the connecting plate 22 causes the rotating ring 23 to move through the connecting rod 24, driving the protective plate 25 towards the automatic tool changer body 4 and the CNC machine tool body 1. Thus, the protective plate 25 can protect the entire working position of the watch case processing. At this time, the rotating rod 27 can be rotated on the connecting plate 26. The rotating rod 27 will contact one side of the rotating ring 23 through the inner wall of the connecting plate 22, thereby fixing the rotation angle of the rotating ring 23 on the connecting plate 22.

[0036] Pulling the baffle 34 causes the connecting rod 32 to rotate within the fixed frame 31, which in turn stretches the coil spring 33. This releases the baffle 34 from its limiting effect on the cleaning brush 35, allowing the cleaning brush 35 to be removed from the fixed frame 31. The cleaning brush 35 can then be used to clean the entire processing environment of the watch case.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
