In addition, the connecting pipe is connected to the inside of the hammerhead. Combined with the internal electric push rod, it can further assist in tool adjustment or provide other functional support, ensuring the stable operation of the processing.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Please refer to Figure 1-4An automatic tool changer for CNC machining of crusher hammers, comprising:

[0030] Mounting bracket 1, with a slider 2 slidably mounted inside the mounting bracket 1. A connecting pipe 11 is rotatably mounted on the bottom surface of the slider 2, and a hammer head 13 is fixedly mounted at the bottom end of the connecting pipe 11. The interior of the connecting pipe 11 is connected to the interior of the hammer head 13. Multiple sliding grooves 18 are formed on the outer wall of the hammer head 13 and are evenly distributed. Multiple crushing blades 15 are slidably mounted in each of the multiple sliding grooves 18. An adjustment component is set inside the mounting bracket 1 and is used to adjust the height of the slider 2. A drive component is set inside the slider 2 and is used to drive the hammer. When the head 13 rotates, and the processing height needs to be adjusted during use, the first motor 9 is started. The first motor 9 drives the second bevel gear 8 at the output shaft end to rotate. Because the second bevel gear 8 meshes with the first bevel gear 7 at the bottom end of the threaded rod 6, it drives the threaded rod 6 to rotate within the mounting frame 1. At this time, the slider 2, which is threadedly connected to the threaded rod 6, moves steadily up and down along the slide rod 5 and the threaded rod 6 under the limiting guide of the slide rod 5 on the other side, realizing precise adjustment of the height of the hammer head 13 to adapt to different processing scenarios. When performing crushing operations, the second motor is started. 10. The output shaft of the second motor 10 drives the second gear 4 at the top to rotate. Since the second gear 4 meshes with the first gear 3, the connecting pipe 11 connected to the bottom end of the first gear 3 rotates, ultimately achieving high-speed rotation of the hammer head 13 to meet the power requirements of crushing processing. In terms of tool use and replacement, the evenly distributed grooves 18 on the outer wall of the hammer head 13 provide mounting and sliding tracks for the crushing blades 15. Multiple crushing blades 15 can move flexibly within the grooves 18. At the same time, the mounting ring 14 is fixedly connected to the crushing blades 15, and fixed rods are used on both sides. The 16 connection, in conjunction with the top limiting rod 17, can fix and adjust the position of the crushing blade 15. When the blade needs to be replaced, the limiting rod 17 is loosened, and the position of the mounting ring 14 on the fixing rod 16 is adjusted, which can drive the crushing blade 15 to slide in the slide groove 18, realizing the quick replacement and position adjustment of the blade, improving the adaptability and processing efficiency of the equipment. In addition, the connecting pipe 11 is connected to the inside of the hammer head 13, and in conjunction with the internal electric push rod 12, it can further assist in the adjustment of the tool or provide other functional support, ensuring the stable operation of the processing process.

[0031] In this embodiment, the adjustment component includes a slide bar 5, which is fixedly installed on one side of the inner side of the mounting frame 1. A threaded rod 6 is rotatably installed on the other side of the inner side of the mounting frame 1. One side of the slider 2 is threadedly connected to the outer wall of the threaded rod 6, and the other side of the slider 2 is slidably connected to the outer wall of the slide bar 5. When the first motor 9 is started, the first motor 9 drives the second bevel gear 8 at the output shaft end to rotate. Since the second bevel gear 8 meshes with the first bevel gear 7 at the bottom end of the threaded rod 6, the threaded rod 6 is driven to rotate within the mounting frame 1. At this time, the slider 2, which is threadedly connected to the threaded rod 6, moves steadily up and down along the slide bar 5 and the threaded rod 6 under the limiting guidance of the slide bar 5 on the other side, so as to achieve precise adjustment of the height of the hammer head 13 to adapt to different processing scenarios.

[0032] In this embodiment, the adjustment assembly also includes a first bevel gear 7, which is fixedly installed at the bottom end of the threaded rod 6. A first motor 9 is provided on one side of the first bevel gear 7, and the bottom surface of the first motor 9 is fixedly connected to the inner bottom surface of the mounting frame 1. A second bevel gear 8 is fixedly installed at one end of the output shaft of the first motor 9, and the second bevel gear 8 meshes with the first bevel gear 7. When the first motor 9 is started, the first motor 9 drives the second bevel gear 8 at the output shaft end to rotate. Because the second bevel gear 8 meshes with the first bevel gear 7 at the bottom end of the threaded rod 6, the threaded rod 6 is driven to rotate within the mounting frame 1. At this time, the slider 2, which is threadedly connected to the threaded rod 6, moves steadily up and down along the slider 5 and the threaded rod 6 under the limiting guidance of the slider 5 on the other side, so as to achieve precise adjustment of the height of the hammer head 13 to adapt to different processing scenarios.

[0033] In this embodiment, the driving component includes a first gear 3, which is rotatably mounted on the top surface of the slider 2. The bottom end of the first gear 3 penetrates the top surface of the slider 2 and is fixedly connected to the top end of the connecting pipe 11. A second gear 4 is provided on one side of the first gear 3. The bottom end of the second gear 4 is rotatably connected to the top surface of the slider 2 and meshes with the first gear 3. A second motor 10 is fixedly mounted on the bottom surface inside the slider 2. The top end of the output shaft of the second motor 10 is fixedly connected to the bottom end of the second gear 4. When the second motor 10 is started, the output shaft of the second motor 10 drives the second gear 4 at the top end to rotate. Since the second gear 4 meshes with the first gear 3, the connecting pipe 11 connected to the bottom end of the first gear 3 rotates, ultimately achieving high-speed rotation of the hammer 13 to meet the power requirements of crushing and processing.

[0034] In this embodiment, multiple mounting rings 14 are movably installed on the outer side wall of the hammer head 13. The multiple mounting rings 14 are fixedly connected to the outer side wall of the corresponding crushing blade 15. The mounting rings 14 are fixedly connected to the crushing blade 15, and the two sides are connected by fixing rods 16. With the limiting rod 17 at the top, the position of the crushing blade 15 can be fixed and adjusted.

[0035] In this embodiment, the same fixing rod 16 is slidably installed on both sides of multiple mounting rings 14. The top ends of the two fixing rods 16 are movably connected to the top surface of the hammer head 13 with a limiting rod 17. When it is necessary to replace the blade, the limiting rod 17 is released and the position of the mounting ring 14 on the fixing rod 16 is adjusted, which can drive the crushing blade 15 to slide in the slide groove 18, so as to realize the quick replacement and position adjustment of the blade.

[0036] In this embodiment, an electric push rod 12 is fixedly installed on the inner bottom surface of the connecting pipe 11. The connecting pipe 11 is connected to the inside of the hammer head 13. Combined with the internal electric push rod 12, it can further assist in tool adjustment or provide other functional support to ensure the stable progress of the processing.

[0037] In actual operation, when this device is in use and the processing height needs to be adjusted, the first motor 9 is started. The first motor 9 drives the second bevel gear 8 at the output shaft end to rotate. Because the second bevel gear 8 meshes with the first bevel gear 7 at the bottom end of the threaded rod 6, it drives the threaded rod 6 to rotate within the mounting frame 1. At this time, the slider 2, which is threadedly connected to the threaded rod 6, moves steadily up and down along the slide rod 5 and the threaded rod 6 under the limiting guide of the slide rod 5 on the other side, realizing precise adjustment of the hammer head 13 height to adapt to different processing scenarios. When performing crushing operations, the second motor 10 is started. The output shaft of the second motor 10 drives the second gear 4 at the top end to rotate. Because the second gear 4 meshes with the first gear 3, it causes the connecting pipe 11 connected to the bottom end of the first gear 3 to rotate, ultimately achieving high-speed rotation of the hammer head 13 to meet the dynamic requirements of crushing processing. Regarding the use and replacement of cutting tools, the evenly distributed grooves 18 on the outer wall of the hammer head 13 provide mounting and sliding tracks for the crushing blades 15. Multiple crushing blades 15 can move flexibly within the grooves 18. At the same time, the mounting ring 14 is fixedly connected to the crushing blades 15 and connected on both sides by the fixing rod 16. With the limit rod 17 at the top, the position of the crushing blades 15 can be fixed and adjusted. When it is necessary to replace the blade, the limit rod 17 is released and the position of the mounting ring 14 on the fixing rod 16 is adjusted, which can drive the crushing blades 15 to slide within the grooves 18, realizing the rapid replacement and position adjustment of the blades, improving the adaptability and processing efficiency of the equipment. In addition, the connecting pipe 11 is connected to the inside of the hammer head 13. Combined with the internal electric push rod 12, it can further assist in tool adjustment or provide other functional support to ensure the stable operation of the processing process.
