For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Please refer to Figure 1-6As shown, an automatic saw blade changing cutting machine includes a frame 10, on which a cutting mechanism 20 and a shifting mechanism 30 for driving the cutting mechanism 20 to move are provided. A blade magazine 11 is provided on the frame 10, holding a plurality of saw blades 40, each saw blade 40 pre-loaded with a saw blade shaft 41. The cutting mechanism 20 includes a cutting seat 21, on which a collet 22 for clamping the saw blade shaft 41 and a cutting motor 23 for driving the collet 22 to rotate are provided. By having saw blade shafts 41 pre-loaded on the saw blades 40, and by using the collet 22 and the cutting motor 23 to drive the saw blades 40 to rotate, the automatic changing of the saw blades 40 can be achieved through the cooperation of the shifting mechanism 30, improving the production efficiency of the equipment and reducing the safety risks to workers.

[0036] Specifically, the tool magazine 11 is equipped with several tool holders 12 and Y-axis drive mechanisms 13 that drive the tool holders 12 to move along the Y-axis direction. The upper end of each tool holder 12 is equipped with a clamp 14 for fixing the saw blade 40. During assembly, the end of the saw blade 40 away from the saw blade shaft 41 is fixed to the clamp 14, and the axial direction of the saw blade shaft 41 is parallel to the axial direction of the collet 22. The clamp 14 is an elastic clamp that can be opened under a certain thrust and automatically clamped, or it can be opened and closed by a cylinder. The shifting mechanism 30 includes an X-axis drive module 31 mounted on the frame 10 and a Z-axis drive module 32 that is controlled by the X-axis drive module to move along the X-axis direction. The cutting seat 21 is connected to the drive end of the Z-axis drive module 32 and is controlled by the Z-axis drive module 32 to move along the Z-axis direction. In this embodiment, the Y-axis drive mechanism 13 is a slide cylinder. It should be understood that, in actual use, a motor combined with a lead screw can also be used to drive the tool holder 12 to move along the Y-axis. The X-axis drive module 31 and the Z-axis drive module 32 are drive modules commonly used in the art, and their specific structures will not be described in detail here. It should also be noted that, in actual use, the shifting mechanism 30 can also be a multi-axis drive module or a multi-axis robot.

[0037] In this utility model, the collet 22 includes an outer sleeve 221 rotatably mounted on the cutting seat 21 and a telescopic rod 222 disposed inside the outer sleeve 221. One end of the telescopic rod 222 is provided with a split chuck 223 that cooperates with the outer sleeve 221 to clamp the saw blade shaft 41. The outer side of the split chuck 223 is provided with a pressing slope that cooperates with the outer sleeve 221 to control the opening and closing of the split chuck 223.

[0038] The cutting seat 21 is also equipped with a driving component 24 that controls the telescopic rod 222 to extend and retract within the outer sleeve 221. The other end of the telescopic rod 222 is rotatably connected to the driving end of the driving component 24. Specifically, the driving end of the driving component 24 is rotatably equipped with a connecting sleeve 25, and the end of the telescopic rod 222 away from the split clamp 223 is rotatably connected to the connecting sleeve 25. The outer sleeve 221 is rotatably connected to the cutting seat 21 via a first bearing 211, and the telescopic rod 222 is rotatably connected to the connecting sleeve 25 via a second bearing 251. The driving end of the driving component 24 is equipped with a connecting shaft 241, which is rotatably connected to the connecting sleeve 25 via a third bearing 252. The connecting shaft 241 and the telescopic rod 222 are coaxially arranged, and a gap is maintained between the opposite ends of the connecting shaft 241 and the telescopic rod 222. By adopting the above arrangement, it is possible to push the telescopic rod 222 to move relative to the outer sleeve 221 while ensuring that the telescopic rod 222 can rotate together with the outer sleeve 221. In this embodiment, the driving component 24 is a cylinder. It should be understood that the driving component 24 can also be replaced by an electric motor.

[0039] In this invention, a drive mounting bracket 26 is fixedly provided on one side of the cutting seat 21, and the driving component 24 is fixedly provided on the drive mounting bracket 26. A synchronous belt 231 is sleeved on the output shaft of the cutting motor 23, and a synchronous pulley is fixedly provided on the outer sleeve 221. The synchronous belt 231 drives the outer sleeve 221 to rotate through the synchronous pulley.

[0040] The replacement process of the saw blade 40 of this utility model is as follows:

[0041] First, the shifting mechanism 30 drives the cutting mechanism 20 to move to the front of the unloaded tool holder 12 in the tool magazine 11. Then, the Y-axis drive mechanism 13 controls the tool holder 12 to move towards the cutting mechanism 20, and causes the clamp 14 on the tool holder 12 to clamp the end of the saw blade 40 away from the saw blade shaft 41. Next, the drive member 24 pushes the telescopic rod 222 to move inside the outer sleeve 221, causing the split chuck 223 of the telescopic rod 222 to extend from the outer sleeve 221, thereby releasing the split chuck 223 from the saw blade shaft 41. Then, the Y-axis drive mechanism 13 controls the tool holder 12 to move away from the cutting mechanism 20. At this time, the saw blade 40 is transferred from the cutting mechanism 20 to the tool holder 12. Then, the shifting mechanism 30 cuts... Mechanism 20 moves to the front of the blade holder 12 of the saw blade 40 to be replaced. Then, the corresponding shaft drive mechanism controls the blade holder 12 to move towards the cutting mechanism 20, and causes the saw blade shaft 41 to extend into the split chuck 223 of the telescopic rod 222. Then, the drive member 24 pushes the telescopic rod 222 to move within the outer sleeve 221, causing the split chuck 223 of the telescopic rod 222 to retract into the outer sleeve 221. The split chuck 223 clamps the saw blade shaft 41 by engaging with the outer sleeve 221 through the pressure slope. Then, the Y-axis drive mechanism 13 controls the blade holder 12 to move away from the cutting mechanism 20. At this time, the saw blade 40 is transferred from the blade holder 12 to the cutting mechanism 20, thus completing the automatic replacement of the saw blade 40.

[0042] In summary, this utility model, by pre-installing a saw blade shaft on the saw blade and using a collet and a cutting motor to drive the saw blade rotation, enables automatic saw blade replacement through the cooperation of a shifting mechanism, thereby improving equipment production efficiency and reducing worker safety risks.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
