[0017] Through the above solution, the turning tool is positioned by the positioning rod and the second positioning groove, which facilitates the installation and disassembly of the turning tool and increases the stability of the turning tool.

[0018] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of each control rod, and the outer circumferential surface of the limiting ring is rotatably connected to the inside of the cutter disc.

[0019] Through the above solution, the control rod is restricted to prevent the control rod from sliding and deviating, thereby increasing the stability of the control rod.

[0020] Furthermore, two limit plates are fixedly connected to the outer circumferential surface of the positioning rod, and the outer surface of each limit plate is slidably connected to the cutter disc via a hollow groove provided inside the cutter disc.

[0033] See also Figure 3 and Figure 4 Four first positioning grooves 7 are provided inside the milling cutter 3, and the outer surfaces of the positioning blocks 6 are slidably connected with the milling cutter 3 through the first positioning grooves 7. The milling cutter 3 is positioned through the positioning blocks 6 and the first positioning grooves 7, which facilitates the installation and disassembly of the milling cutter 3 and improves the stability of the milling cutter 3 during operation.

[0034] See also Figure 3 , Figure 4 and Figure 5The outer circumferential surface of each slide rod 10 is fixedly sleeved with a ring 11, and the outer surface of each ring 11 is slidably connected to the rotating plate 8 through a hollow groove opened inside the rotating plate 8, thereby restricting the slide rod 10 to prevent the slide rod 10 from falling off easily and increasing the stability of the slide rod 10 and the positioning block 6.

[0035] See also Figure 2 , Figure 3 and Figure 4 Four equidistantly arranged paddles 12 are fixedly connected to the outer circumferential surface of the rotating plate 8. The outer surfaces of the paddles 12 are slidably connected to the cutter disc 2 through empty grooves opened inside the cutter disc 2, so that the rotating plate 8 can be easily controlled by the paddles 12, providing convenience for the staff.

[0036] See also Figure 4 and Figure 5 A reinforcement sheet 13 is fixedly connected to the front of one of the paddles 12, and a bolt 14 is connected to the internal thread of the reinforcement sheet 13. The outer circumferential surface of the bolt 14 is connected to the internal thread of the cutter disc 2 to reinforce the rotating plate 8 to prevent the rotating plate 8 from rotating easily, thereby increasing the stability of the positioning of the milling cutter 3.

[0037] See also Figure 3 A second positioning groove 18 is provided inside each turning tool 17, and the outer circumferential surface of the positioning rod 16 is slidably plugged with the turning tool 17 through the second positioning groove 18. The turning tool 17 is positioned by the positioning rod 16 and the second positioning groove 18, which facilitates the installation and disassembly of the turning tool 17 and increases the stability of the turning tool 17.

[0038] See also Figure 3 The outer circumference of each control rod 15 is fixedly sleeved with a limit ring 19, and the outer circumference of the limit ring 19 is rotatably connected to the inside of the cutter head 2 to limit the control rod 15, prevent the control rod 15 from sliding and deviating, and increase the stability of the control rod 15.

[0039] See also Figure 3 Two limit plates 20 are fixedly connected to the outer circumferential surface of the positioning rod 16. The outer surface of each limit plate 20 is slidably connected to the cutter disc 2 through a slot opened inside the cutter disc 2, thereby limiting the positioning rod 16 and preventing the positioning rod 16 from rotating with the control rod 15, so as to enable the positioning rod 16 to always move laterally.

[0040] A CNC turning and milling compound machine tool in the present embodiment drives the slide bar 10 to move during the rotation of the rotating plate 8, prompting the slide bar 10 to drive the positioning block 6 to be retracted and released with the slide groove 5 as a track under the action of the slide groove 5 and the inclined groove 9, and drives the positioning rod 16 to move during the rotation of the control rod 15, prompting the positioning rod 16 to move into the second positioning groove 18 or move out from the second positioning groove 18, thereby facilitating the positioning or disassembly of the milling cutter 3 and the turning tool 17 and increasing the stability of the milling cutter 3 and the turning tool 17, and solving the problem that the stability of positioning the turning tool 17 using a spring is low and has certain safety hazards.

[0041] It should be noted that the angles between the chute grooves 5 are all 90 degrees, the angles between the inclined grooves 9 are all 90 degrees, and the positions of the chute grooves 5 and the inclined grooves 9 correspond to each other.

[0042] The working principle of the above embodiment is:

[0043] When the milling cutter 3 needs to be disassembled, the bolt 14 is first removed, and then the rotating plate 8 is rotated by the paddle 12. During the rotation of the rotating plate 8, the slide rod 10 will be driven to move. The slide rod 10 drives the positioning block 6 to move outward with the slide groove 5 as the track under the action of the slide groove 5 and the inclined groove 9, prompting the positioning block 6 to move out from the inside of the first positioning groove 7, canceling the positioning restriction on the milling cutter 3, and then the milling cutter 3 can be removed. When the turning tool 17 needs to be disassembled, the control rod 15 is rotated to drive the positioning rod 16 to move, prompting the positioning rod 16 to move out from the inside of the second positioning groove 18, canceling the positioning restriction on the turning tool 17, and then the turning tool 17 can be removed.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
