[0032] Furthermore, a groove is provided at the corresponding position of the base plate 1 and the limiting post 315, and the limiting post 315 is movably connected inside the groove, which facilitates the alternation of the two sets of tool magazines, increases the tool magazine capacity, and makes it convenient for the staff to change tools in the tool magazine.

[0033] Furthermore, there are two slide rail brackets 312, and the two slide rail brackets 312 are symmetrically distributed with the center line of the front of the base plate 1 as the axis of symmetry, which facilitates a more stable movement process.

[0034] Furthermore, the adjustment assembly 32 includes a mounting bracket 321, which is fixedly connected to the top of the second slide table 314. A connecting platform 322 is fixedly connected to the bottom of the mounting bracket 321. A motor 323 is fixedly connected to the bottom of the connecting platform 322. The output end of the motor 323 extends through the connecting platform 322 and is fixedly connected to a threaded rod 325 inside. A limit rod 326 is fixedly connected inside the connecting platform 322. A movable frame 327 is slidably connected to the outside of the limit rod 326. A support frame 324 is fixedly connected to the top of the movable frame 327, which facilitates the adjustment of the height of the tool holder 43, thereby meeting the subsequent placement process of tools of different lengths.

[0035] Furthermore, the movable frame 327 is slidably connected to the mounting frame 321, the movable frame 327 is slidably connected to the connecting platform 322, and the movable frame 327 is threadedly connected to the threaded rod 325, which facilitates a more stable adjustment process.

[0036] Example 2:

[0037] Based on Example 1, please refer to Figure 6-7 Furthermore, in conjunction with Embodiment 1, the auxiliary tool changing mechanism 4 includes a limiting frame 41, which is fixedly connected to the top of the support frame 324. A sliding plate 42 is slidably connected inside the limiting frame 41. A tool clip 43 is fixedly connected to the right side of the sliding plate 42.

[0039] In actual operation, when this device is used, the threaded rod is first used as a T-type threaded rod to give it self-locking properties. After the operator moves the device to the designated installation position on the CNC machine tool worktable, the base plate 1 is installed on the CNC machine tool using the locking bolts. After installation, the operator adjusts it according to the tool size. The operator pulls the movable plate 46, and the movement of the movable plate 46, in conjunction with the spring 45, causes the locking block 47 to move. The sliding plate 42 slides inside the limit frame 41, causing the tool holder 43 to move until the installation position of different tools is met. Then, the movable plate 46 is released, and the locking block moves under the action of the spring 45. 47 is inserted into the limit frame 41. After installation, the operator adjusts it according to the tool length. The motor 323 rotates the threaded rod 325, which, in conjunction with the limit rod 326, moves the movable frame 327, thereby moving the support frame 324 and adjusting the height of the tool holder 43. The electric slide rail 311 moves the first slide 313 outside the slide rail frame 312, and the limit post 315 moves the second slide 314 inside the first slide 313, thus realizing the alternating movement of the two sets of second slides 314. This satisfies the need to alternate between the two sets of tool magazines, increasing the tool magazine capacity and facilitating tool changing operations for the operator.
