During the dicing process, the cutting head, as a key component that directly contacts the workpiece, has a significant impact on machining accuracy and efficiency. Therefore, to improve the machining efficiency, accuracy, and safety of dicing machines, a quick-change device for the cutting head is needed.

[0003] A quick-change device for dicing cutter heads is a specialized piece of equipment or mechanism designed for dicing machines to enable rapid, stable, and convenient replacement of cutter heads. Traditional dicing machine cutter head replacement methods are often complex and time-consuming. Because the connection between the cutter head and the dicing machine is quite tight, special tools are required for disassembly and installation during replacement, which not only increases the difficulty of operation but also prolongs the replacement time. Furthermore, improper disassembly and installation methods may damage the cutter head, affecting its service life and machining accuracy. Utility Model Content

[0009] Preferably, a U-shaped block is fixedly connected to the outer wall of the connecting cylinder, and a blade is rotatably connected inside the U-shaped block.

[0010] Preferably, a fixing cylinder is fixedly connected inside the limiting block, and a locking block is slidably connected inside the fixing cylinder.

[0011] Preferably, a second spring is fixedly connected to the outer wall of the card block, and the outer wall of the second spring is slidably connected to the inside of the fixed cylinder.

[0012] Preferably, the outer wall of the card block is slidably connected to the inside of the connecting cylinder.

[0013] Preferably, the connecting cylinder has a slot inside, and the outer wall of the locking block is slidably connected to the inner wall of the slot.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by turning the handle, the threaded rod is rotated, which in turn causes the connecting block to slide.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a quick-change device for a dicing machine cutter head, comprising a limiting post 1, a connecting frame 2 fixedly connected inside the limiting post 1, a threaded rod 3 rotatably connected inside the connecting frame 2, a handle 4 fixedly connected to the outer wall of the threaded rod 3, the outer wall of the handle 4 rotatably connected to the outer wall of the connecting frame 2, a connecting block 5 threadedly connected to the outer wall of the threaded rod 3, a connecting shaft 9 fixedly connected inside the connecting block 5, a connecting rod 6 rotatably connected to the outer wall of the connecting shaft 9, a slider 7 rotatably connected to the outer wall of the connecting rod 6, a slide rail 8 slidably connected inside the slider 7, the outer wall of the slide rail 8 fixedly connected to the inner wall of the connecting frame 2, the outer wall of the slider 7 slidably connected to the inside of the connecting frame 2, a limiting block 10 fixedly connected to the outer wall of the slider 7, and an elastic component provided on the outer wall of the limiting block 10 for auxiliary support of the limiting block 10.

[0025] Specifically, the handle 4 serves to limit the threaded rod 3. Twisting the handle 4 causes the threaded rod 3 to rotate inside the connecting frame 2. The threaded rod 3 causes the connecting block 5 to slide. The connecting block 5 pulls the connecting rod 6 to rotate via the connecting shaft 9. The connecting rod 6 causes the slider 7 to slide on the slide rail 8. The slide rail 8 supports and limits the slider 7. When the slider 7 slides in the connecting frame 2, it causes the limiting block 10 to slide. The connecting frame 2 supports and limits the slider 7.

[0026] Reference Figure 3 and Figure 4 The elastic component includes a telescopic rod 14, the outer wall of which is fixedly connected to the outer wall of the limiting block 10, and a first spring 15 is slidably connected to the outer wall of the telescopic rod 14, the outer wall of which is fixedly connected to the outer wall of the limiting block 10.

[0027] Specifically, when the cutter head is disassembled, the sliding of the limiting rod will compress the telescopic rod 14 and the first spring 15. When the cutter head is installed, the rebound of the first spring 15 and the limiting of the telescopic rod 14 will make the connection between the limiting block 10 and the connecting cylinder 11 more stable.

[0028] Reference Figure 2 and Figure 4 The outer wall of the limiting post 1 is slidably connected to the connecting cylinder 11, and the inner wall of the connecting cylinder 11 is slidably connected to the outer wall of the limiting block 10; the outer wall of the connecting cylinder 11 is fixedly connected to the U-shaped block 12, and the inside of the U-shaped block 12 is rotatably connected to the blade 13.

[0029] Specifically, the connecting cylinder 11 serves to support the limiting U-shaped block 12, and the U-shaped block 12 serves to support the limiting blade 13.

[0030] Reference Figure 1 , Figure 2 and Figure 4 The limiting block 10 is fixedly connected to the inside of the fixed cylinder 16, and the fixed cylinder 16 is slidably connected to the inside of the locking block 17; the outer wall of the locking block 17 is fixedly connected to the second spring 18, and the outer wall of the second spring 18 is slidably connected to the inside of the fixed cylinder 16; the outer wall of the locking block 17 is slidably connected to the inside of the connecting cylinder 11; the connecting cylinder 11 has a slot 19 inside, and the outer wall of the locking block 17 is slidably connected to the inner wall of the slot 19.

[0031] Specifically, the limiting block 10, through the fixed cylinder 16, drives the locking block 17 to align with the slot 19. Under the blocking action of the connecting cylinder 11, it further drives the locking block 17 to slide in the fixed cylinder 16. The fixed cylinder 16 limits the locking block 17. While the locking block 17 slides, it also compresses the second spring 18. Under the rebound action of the second spring 18, the locking block 17 is locked in the slot 19 in the connecting cylinder 11, which makes the connecting cylinder 11 more stable. This ensures that the cutter head is always firmly connected to the dicing machine during processing, improving processing safety.

[0032] Working principle: When the device is needed, first insert the limiting post 1 and the connecting frame 2 into the connecting cylinder 11. Then, turn the handle 4 to drive the threaded rod 3 to rotate inside the connecting frame 2. The threaded rod 3 drives the connecting block 5 to slide. The connecting block 5 pulls the connecting rod 6 to rotate through the connecting shaft 9. The connecting rod 6 drives the slider 7 to slide on the slide rail 8. When the slider 7 slides in the connecting frame 2, it can drive the limiting block 10 to slide. At this time, the limiting block 10 drives the locking block 17 to align with the slot 19 through the fixed cylinder 16. Under the obstruction of the connecting cylinder 11, the locking block 17 will slide in the fixed cylinder 16. When the locking block 17 slides, it will squeeze the second spring 18. Under the rebound of the second spring 18, the locking block 17 can be locked in the slot 19 in the connecting cylinder 11. At the same time, the telescopic rod 1... Supported by the elastic force of spring 4 and the first spring 15, the connection between the limiting block 10 and the connecting cylinder 11 can be made more stable. When the handle 4 is turned in the opposite direction, the limiting block 10 will move in the opposite direction, thereby separating the limiting block 10 from the connecting cylinder 11. The U-shaped block 12 and the blade 13 on the connecting cylinder 11 can then be replaced. This device not only achieves the effect of quickly changing the cutting head, but also significantly shortens the replacement time and reduces the downtime of the production line, thereby improving the overall production efficiency. At the same time, it also reduces the number and duration of downtime, which helps to reduce production costs. It also achieves the effect of making the cutting head more stable, thereby ensuring that the cutting head always maintains the correct position and angle during processing, thus ensuring processing accuracy, reducing the impact and wear on the cutting head, and extending the service life of the cutting head.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
