[0029] like Figures 1 to 4 As shown: A milling and turning compound disc tool magazine includes: a tool disc 1 and a plurality of tool clamping assemblies 2 arranged circumferentially along the tool disc 1, and a drive assembly 3 disposed at the center of the tool disc 1;

[0030] The cutter head 1 has multiple mounting surfaces 11 arranged around its circumference. The cutter clamp assembly 2 includes a fixing block 21 and a spring piece 22 disposed on the fixing block 21 near the inner side of the cutter head 1. The fixing block 21 is disposed on the mounting surface 11 and is perpendicular to the cutter head 1. The fixing block 21 has a through groove 211 on the side away from the cutter head 1. The spring piece 22 is detachably disposed on the fixing block 21. The spring piece 22 includes a body 221 and arc-shaped claws 222 symmetrically disposed on the body 221. The two arc-shaped claws 222 are located on both sides of the groove 211. The inner sides of the opposite ends of the two arc-shaped claws 222 are provided with protrusions 222a for fixing the cutter 01.

[0031] By designing the spring 22 to be detachably connected to the fixing block 21, when the tool holder is worn or damaged, only the spring 22 needs to be replaced instead of the entire tool holder assembly 2, effectively reducing maintenance costs.

[0032] The spring clips 22 are set on both sides of the groove 211 of the fixing block 21, and are positioned by the symmetrically arranged arc-shaped claws 222 in conjunction with the groove 211, which improves the stability and centering accuracy of the tool 01 installation. The assembly process is simple and suitable for automated assembly or on-site replacement. The inner side of the end of the arc-shaped claws 222 on both sides of the spring clips 22 is provided with protrusions 222a, which clamp the tool 01 by the elastic deformation of the spring clips 22. It has good clamping force and self-adaptive ability, and can keep the tool 01 stable and not fall off in the environment of vibration or high-speed rotation.

[0033] During the insertion of the tool 01, the arc-shaped claws 222 on both sides of the spring 22 undergo elastic deformation and open outward under the insertion force of the tool 01. When the tool 01 continues to be inserted and enters the groove 211 of the fixing block 21, the arc-shaped claws 222 automatically spring back to their original position under the action of elastic restoring force. The protrusion 222a on the inner side of its end abuts against the outer wall of the tool 01, thereby limiting and clamping the tool 01, effectively preventing the tool 01 from shaking or accidentally popping out, and improving the clamping stability and reliability.

[0034] As an optional connection method, the mounting surface 11 and the fixing block 21, as well as the spring piece 22 and the fixing block 21, are fixedly connected by positioning pins and locking components. The positioning pins are used to ensure the positional accuracy during the assembly process, while the locking components are used to provide clamping force and anti-loosening function, which can effectively improve the overall stability and vibration resistance of the connection structure and facilitate later maintenance and replacement.

[0035] In this embodiment, the number of mounting surfaces 11 of the cutter head 1 is 24, and 24 tool clamping assemblies 2 are provided accordingly. It should be noted that the number of tool clamping assemblies 2 can be adjusted according to the actual size of the cutter head 1 and the processing requirements, such as 12, 18, 30, etc., all of which are within the protection scope of this application.

[0036] In this embodiment, the mounting surface 11 is inclined to the axis of the tool head 1, and the mounting surface 11 is parallel to the end face of the spindle. On the one hand, the parallelism between the mounting surface 11 and the end face of the spindle ensures that the tool holder is aligned with the end face of the spindle after installation, which is beneficial for axial alignment of the tool 01 and improves the accuracy and efficiency of tool changing operation. On the other hand, since the tool holder assembly 2 is installed along the inclined mounting surface 11, the tools 01 are also arranged at an incline, increasing the distance between adjacent tools 01. This effectively reduces the risk of interference between tools 01 or tool holders during tool changing, avoids collisions, and improves safety. Furthermore, the inclined mounting surface 11 balances the distribution density of tools 01 with the operating space, which helps to reasonably arrange more tool holder assemblies 2 within the limited size of the tool head 1, improving the overall machining flexibility.

[0037] The spring piece 22 has a protrusion 223 in the middle. The protrusion 223 is inserted into the recess of the tool 01 to achieve auxiliary limiting and stable positioning of the tool 01. The protrusion 223 and the groove 211 on the tool 01 form a matching structure, which can effectively limit the positional displacement of the tool 01 during the clamping process and improve the positioning accuracy of the tool 01.

[0038] As a preferred embodiment of the above, the inner side of the arc-shaped claw 222 connected to the body 221 is provided with a relief groove 224, which effectively improves the elastic deformation capability of the area, so that the arc-shaped claw 222 has a larger deformation space during the clamping or releasing of the tool 01, avoiding structural interference or damage caused by stress concentration, thereby extending the service life of the tool clamp assembly 2.

[0039] In this embodiment, arc grooves 225 are provided on both the inner and outer sides of the connection between the body 221 and the arc-shaped claw 222, which effectively disperses the stress concentration area of ​​the connection part, reduces the risk of fracture or plastic deformation, and enhances the flexibility and recovery ability of the spring piece 22 under stress, thereby improving the durability and stability of the overall blade clamp assembly 2.

[0040] The size of the arc-shaped chuck 222 gradually increases towards the body 221, which helps to enhance the structural strength of its connection part, prevents breakage or loosening when clamping the tool 01, and improves the overall clamping stability and durability.

[0041] As a preferred embodiment, the protrusion 222a has inclined surfaces 222b on both sides along the infeed direction of the tool 01, which can guide and buffer the tool 01 during insertion, effectively reducing the wear and impact caused by hard contact between the tool 01 and the protrusion 222a of the arc-shaped chuck 222, and improving the clamping smoothness and service life of the clamping structure.

[0042] In this embodiment, the bottom of the groove 211 is provided with a uniform convex edge structure 211a. The cross section of the convex edge structure 211a is trapezoidal. The periphery of the tool 01 is provided with a concave ring 011 that matches the convex edge structure 211a. By providing multiple convex edge structures 211a with trapezoidal cross sections at the bottom of the groove 211 and forming an interlocking fit with the concave ring 011 provided around the tool 01, the radial and axial positioning accuracy of the tool 01 can be effectively improved, preventing the tool 01 from shaking or shifting during high-speed rotation or tool changing, thereby improving machining stability and safety.

[0043] As a preferred embodiment of the above, the drive assembly 3 includes a motor 31, a reducer 32, and a connecting plate 33. After the motor 31 is reduced in speed by the reducer 32, it drives the connecting plate 33 to rotate. The connecting plate 33 is detachably connected to the cutter head 1. By designing the drive assembly 3 as a combination structure of the motor 31, the reducer 32, and the connecting plate 33, the rotational speed of the cutter head 1 can be effectively controlled, improving the smoothness and response speed of the tool changing process. At the same time, the connecting plate 33 and the cutter head 1 adopt a detachable structure, which facilitates daily maintenance and replacement of the cutter head 1, improving the maintainability and versatility of the whole machine.

[0044] The drive assembly 3 also includes a bracket 34 and a photoelectric sensor switch 35 mounted on the bracket 34, which is used to accurately detect whether there is a tool 01 at the tool change position. When a tool 01 is detected at the tool change position, the system can automatically prevent the spindle from performing the tool change action, effectively preventing the tool 01 from colliding due to misoperation or system failure, and improving the safety and automation level of equipment operation.
