[0012] Preferably, a nut seat is fixedly mounted on the bottom of the mounting plate, and a tool is threadedly engaged on the nut seat.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] By installing the required tool on the nut seat before turning, and then controlling the corresponding motor to start, the motor drives the threaded rod to rotate. Through the guide groove and the guide block, when the threaded rod rotates, it will drive the slider and the lifting block to descend, and then drive the mounting plate and the tool to descend to perform turning work. When the tool needs to be replaced, the relevant motor is controlled to reverse, and the motor corresponding to the tool to be replaced is controlled to start, so that the old tool rises while the new tool to be replaced descends.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a tool replacement device for a CNC machine tool. Figure 1-3 , a CNC machine tool tool changing device, comprising a mounting block 1, a screw rod 2 is fixedly installed on the top of the mounting block 1, a hollow chamber 3 is opened in the mounting block 1, a vertical rod 4 is fixedly installed at the bottom of the hollow chamber 3, connecting blocks 5 are respectively arranged on the four sides of the vertical rod 4, lifting blocks 6 extending to the outside of the mounting block 1 are fixedly installed on the connecting blocks 5, and mounting plates 7 are fixedly installed on the lifting blocks 6. Slide grooves 8 are opened on the four sides of the vertical rod 4, and sliders 9 cooperating with the slide grooves 8 are fixedly installed on the connecting blocks 5. Four groups of motors 10 are fixedly installed on the top of the vertical rod 4, and threaded rods 11 extending into the slide grooves 8 and cooperating with the sliders 9 are installed at the output end of the motor 10. Moving grooves 12 cooperating with the lifting block 6 are symmetrically opened on the four sides of the mounting block 1, and two groups of guide grooves 13 are symmetrically opened on both sides of the moving groove 12. Two groups of guide blocks 14 cooperating with the guide grooves 13 are fixedly installed on the lifting block 6;

[0021] By adopting the above technical solution, the required tool 16 is installed on the nut seat 15 before turning, and then the corresponding motor 10 is controlled to start. The motor 10 drives the threaded rod 11 to rotate. Through the guide groove 13 and the guide block 14, when the threaded rod 11 rotates, it will drive the slider 9 and the lifting block 6 to descend, and then drive the mounting plate 7 and the tool 16 to descend to perform turning work. When the tool 16 needs to be replaced, the relevant motor 10 is controlled to reverse, and the motor 10 corresponding to the tool 16 that needs to be replaced is controlled to start, so that the old tool 16 rises while the new tool 16 that needs to be replaced descends. There is no need to remove the tool 16 and then install it, which saves working time and improves work efficiency.

[0022] Reference Figure 1 A nut seat 15 is fixedly mounted on the bottom of the mounting plate 7, and a tool 16 is threadedly engaged on the nut seat 15;

[0023] By adopting the above technical solution, the tool 16 is installed on the nut seat 15 through threads, which can improve the stability of the tool 16, prevent it from falling during the turning process, and improve the safety of the device.

[0024] The implementation principle of a tool changing device for a CNC machine tool in an embodiment of the present application is as follows: before turning, the required tool 16 is installed on the nut seat 15, and then the corresponding motor 10 is controlled to start. The motor 10 drives the threaded rod 11 to rotate. Through the action of the guide groove 13 and the guide block 14, when the threaded rod 11 rotates, it will drive the slider 9 and the lifting block 6 to descend, and then drive the mounting plate 7 and the tool 16 to descend to perform turning work. When the tool 16 needs to be replaced, the relevant motor 10 is controlled to reverse, and the motor 10 corresponding to the tool 16 that needs to be replaced is controlled to start, so that the old tool 16 rises while the new tool 16 that needs to be replaced descends. There is no need to remove the tool 16 and then install it, which saves working time and improves work efficiency.
