[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 An automatic tool-changing engraving machine includes a base 1, a worktable 2 and a housing 3 mounted on the top of the base 1, the worktable 2 being located at the bottom inner part of the housing 3, a protective door 4 mounted on the front of the housing 3, a tool magazine mechanism 5 mounted on the side of the housing 3, an adjustment mechanism 6 mounted on the top inner part of the housing 3, and a fourth motor 7 mounted on the bottom of the adjustment mechanism 6. The adjustment mechanism 6 adjusts the position of the fourth motor 7 for changing tools in the tool magazine mechanism 5. The tool magazine mechanism 5 includes a first housing 51 fixed to the side of the housing 3, a first motor 52 mounted on the top of the first housing 51, the output shaft of the first motor 52 being inserted into the interior of the first housing 51 and connected to a first movable frame 53, a tool holder 54 mounted on the side of the first movable frame 53, and tools 55 stored on the tool holder 54. The tool holder 54 has a semi-circular ring structure, and the number of tools 55 is several groups, with the tools 55 being snapped onto the tool holder 54.

[0021] In one embodiment, the adjustment mechanism 6 includes a mounting bracket 61 fixed to the inner top of the housing 3 and a second motor 62 mounted on the side of the housing 3. The second motor 62 is inserted into the mounting bracket 61 and connected to a first threaded post 63. A slider 64 is threadedly connected to the first threaded post 63. The slider 64 is slidably connected to the mounting bracket 61. A lifting mechanism 65 is mounted at the bottom of the slider 64. A fourth motor 7 is mounted at the bottom of the lifting mechanism 65. The lifting mechanism 65 includes a fixing bracket 651 fixed to the bottom of the slider 64. A second housing 652 is mounted at the inner bottom of the fixing bracket 651. A threaded sleeve 653 is rotatably connected inside the second housing 652. A first bevel gear 654 is fixedly sleeved on the threaded sleeve 653. A second threaded post 655 is threadedly connected inside the threaded sleeve 653. A second movable frame 658 is mounted at the bottom of the second threaded post 655. A third motor is mounted on the side of the second housing 652. 656, the third motor 656 is inserted into the interior of the second housing 652 and connected to the second bevel gear 657. The second movable frame 658 and the fixed frame 651 are slidably connected. The first bevel gear 654 and the second bevel gear 657 are meshed and driven. The fourth motor 7 is installed at the bottom of the second movable frame 658. A semi-circular tool holder is used in conjunction with a snap-fit ​​tool to simplify the tool storage structure, reduce the top space occupied, and avoid the waste of top space caused by the ring conveying mechanism of the traditional chain tool magazine. The tool magazine mechanism drives the movable frame to rotate through the first motor, realizing the rapid positioning and loading and unloading of tools. The mechanical linkage structure is simpler and reduces failures. The adjustment mechanism integrates horizontal movement (first threaded column and slider) and vertical lifting (lifting mechanism) functions. It is independently controlled by the second and third motors, reducing redundant mechanical linkage structures and improving space utilization. The fourth motor is directly installed at the bottom of the movable frame, shortening the tool drive shaft length and improving machining accuracy.

[0022] The equipment uses a tool magazine mechanism 5 to store and position tools. The tool holder 54 is designed as a semi-circular ring structure, with multiple sets of tools 55 clamped onto it. The first motor 52 drives the first movable frame 53 to rotate, bringing the target tool to the tool changing position. During tool changing, the adjustment mechanism 6 works in conjunction: the second motor 62 drives the first threaded column 63 to rotate, and the first threaded column 63, through threaded transmission with the slider 64, moves the slider 64 laterally to directly above the tool holder 54. The output shaft of the third motor 656 drives the second bevel gear 657 to rotate, and the second bevel gear 657, through meshing with the first bevel gear 654, drives the threaded sleeve 653 to rotate. The threaded sleeve 653, through meshing with the threaded column... The threaded drive of 655 causes the second movable frame 658 to descend vertically, driving the second movable frame 658 and the fourth motor 7 to grab the target tool. Subsequently, the output shaft of the fourth motor 7 engages with the tool 55. The adjusting mechanism 6 drives the fourth motor 7 and the tool 55 to move to the machining position. Throughout the process, the fourth motor 7 is directly mounted on the bottom of the movable frame, shortening the drive shaft length, reducing vibration and improving machining accuracy. The equipment achieves coordinated operation of horizontal movement, vertical lifting and lowering, and tool rotation by independently controlling each motor, simplifying the complex mechanical linkage of the traditional chain tool magazine, reducing the failure rate, and optimizing space utilization with the semi-circular tool holder structure to meet the requirements of efficient and high-precision automatic tool changing.

[0023] In summary, compared with existing technologies, this utility model adopts a semi-circular tool holder with a snap-fit ​​tool, simplifying the tool storage structure, reducing top space occupation, and avoiding the top space waste caused by the ring conveying mechanism of traditional chain tool magazines. The tool magazine mechanism drives the first movable frame to rotate through the first motor, realizing rapid positioning and loading / unloading of tools. The mechanical linkage structure is simpler, reducing failures. The adjustment mechanism integrates horizontal movement (first threaded column and slider) and vertical lifting (lifting mechanism) functions, which are independently controlled by the second and third motors, reducing redundant mechanical linkage structures and improving space utilization. The fourth motor is directly installed at the bottom of the second movable frame, shortening the tool drive shaft length and improving machining accuracy.
