Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an automatic tool changing system for a gantry machining center, including a machining base 1 and an adjustment mechanism 4. A machining table 2 is mounted on the surface of the machining base 1, a column 3 is mounted on the surface of the machining base 1, an adjustment mechanism 4 is provided on one side of the surface of the column 3, a mounting base 5 is mounted on one end of the adjustment mechanism 4, a mounting mechanism 6 is provided on one side of the surface of the mounting base 5, a tool holder 7 is mounted on one side of the surface of the mounting base 5, a crossbeam 8 is mounted on the top of the column 3, a robot arm 9 is mounted on one side of the surface of the column 3, and a spindle 10 is mounted on one side of the surface of the crossbeam 8.

[0021] The adjustment mechanism 4 includes an adjustment base 401, an adjustment groove 402, a limiting groove 403, a drive motor 404, a one-way screw 405, a slider 406, and a limiting block 407. The adjustment base 401 is fixedly connected to one side of the surface of the column 3. An adjustment groove 402 is formed on one side of the surface of the adjustment base 401, and a limiting groove 403 is formed on the other side of the surface of the adjustment base 401. The drive motor 404 is mounted on the top of the adjustment base 401. A one-way screw 405 is installed inside the adjustment groove 402. One end of the one-way screw 405 passes through the slider 406. A limiting block 407 is fixedly connected to one side of the surface of the slider 406. The adjustment mechanism 4 utilizes the adjustment base 401, adjustment groove 402, limiting groove 403, drive motor 404, one-way screw 405, slider 406, and limiting block 407. When a tool change is required, the drive motor 404 is turned on. At this time, the drive motor 404 drives the one-way lead screw 405 to rotate inside the adjustment groove 402. Since the slider 406 is threaded on the surface of the one-way lead screw 405 and the slider 406 is fitted inside the adjustment groove 402, and the limiting block 407 fixedly connected to one side of the surface of the slider 406 is fitted inside the limiting groove 403, the slider 406 moves up and down along the one-way lead screw 405 inside the adjustment groove 402 when the one-way lead screw 405 rotates. The limiting block 407 moves with the slider 406 inside the limiting groove 403. At this time, the slider 406 drives the mounting base 5 to move up and down. The appropriate tool holder 7 is moved to the surface of the robot arm 9 according to the required tool head, and then the tool change operation is performed by the robot arm 9.

[0022] Furthermore, the limiting groove 403 is connected to the adjusting groove 402, and the limiting block 407 is fitted inside the limiting groove 403. Through the setting of the limiting block 407, the limiting block 407 can limit the slider 406 during use, so that the slider 406 can move up and down along the one-way lead screw 405 inside the adjusting groove 402.

[0023] Furthermore, the output end of the drive motor 404 is connected to the one-way lead screw 405. With the drive motor 404 in use, turning on the drive motor 404 can drive the one-way lead screw 405 to rotate inside the adjustment groove 402.

[0024] Furthermore, the slider 406 is fitted inside the adjusting groove 402, and the slider 406 is threaded onto the surface of the one-way lead screw 405. With the slider 406 in use, when the slider 406 moves up and down along the one-way lead screw 405 inside the adjusting groove 402, it can drive the mounting base 5 to move, thereby driving the tool holder 7 mounted on the surface of the mounting base 5 to move up and down.

[0025] Furthermore, the mounting mechanism 6 includes a limiting hole 601, a positioning block 602, a positioning groove 603, a threaded groove 604, and a bolt 605. A limiting hole 601 is formed on one side of the surface of the mounting base 5, and a positioning block 602 is fixedly connected to one side of the surface of the mounting base 5. A positioning groove 603 is formed on one side of the surface of the slider 406, and a threaded groove 604 is formed on one side of the surface of the slider 406. A bolt 605 passes through the interior of the limiting hole 601. Through the arrangement of the limiting hole 601, the positioning block 602, the positioning groove 603, the threaded groove 604, and the bolt 605... In use, the positioning block 602, which is fixedly connected to one side of the surface of the mounting base 5, is fitted into the positioning groove 603 opened on one side of the surface of the slider 406. When the positioning block 602 is fully fitted into the positioning groove 603, the limiting hole 601 opened on one side of the surface of the mounting base 5 is aligned with the threaded groove 604 opened on one side of the surface of the slider 406. Then, one end of the bolt 605 is threaded through the limiting hole 601 and then threaded to the slider 406 through the threaded groove 604. At this time, the bolt 605 fixes the mounting base 5 on the surface of the slider 406.

[0026] Furthermore, the positioning block 602 and the positioning groove 603 are sized to match, and the bolt 605 is threadedly connected to the slider 406 through the threaded groove 604. With the setting of the positioning block 602, when the positioning block 602 is fully fitted inside the positioning groove 603 during use, the position of the limiting hole 601 and the threaded groove 604 can be aligned.

[0027] Furthermore, the tool holder 7 is provided with nine sets, and the robotic arm 9 is installed on the surface of the column 3 which is provided with the adjustment mechanism 4. Through the arrangement of the tool holder 7 and the robotic arm 9, multiple sets of tool heads can be installed in the nine sets of tool holder 7 during use, which facilitates subsequent tool changing operations. The robotic arm 9 can easily remove the tool head on the spindle 10 and replace the tool head on the tool holder 7 at the same time.

[0028] Working principle: The positioning block 602, which is fixedly connected to one side of the surface of the mounting base 5, is fitted into the positioning groove 603 opened on one side of the surface of the slider 406. When the positioning block 602 is fully fitted into the positioning groove 603, the limiting hole 601 opened on one side of the surface of the mounting base 5 is aligned with the threaded groove 604 opened on one side of the surface of the slider 406. Then, one end of the bolt 605 is threaded through the limiting hole 601 and then threaded into the slider 406 through the threaded groove 604. At this time, the bolt 605 fixes the mounting base 5 on the surface of the slider 406. When a tool change operation is required, the drive motor 404 is turned on, and the drive motor 404 drives the one-way lead screw. 405 rotates inside the adjusting groove 402. Since the slider 406 is threaded onto the surface of the one-way screw 405 and the slider 406 is fitted inside the adjusting groove 402, and the limiting block 407 fixedly connected to one side of the surface of the slider 406 is fitted inside the limiting groove 403, when the one-way screw 405 rotates, the slider 406 moves up and down along the one-way screw 405 inside the adjusting groove 402. The limiting block 407 moves with the slider 406 inside the limiting groove 403. At this time, the slider 406 drives the mounting base 5 to move up and down. The appropriate tool holder 7 is moved to the surface of the robot arm 9 according to the required tool head, and then the tool changing operation is performed by the robot arm 9.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
