The propulsion mechanism 4 is movably connected to the tool clamping member 7. The tool clamping member 7 can swing along the opening 13 to the outside of the outer shell 1 through the propulsion mechanism 4. At the opening 13, the outer cover 12 is provided with a plurality of flexible fiber push rods 2. The axial direction of the flexible fiber push rods 2 is parallel to the frame of the surrounding frame 11. When the tool clamping member 7 passes through the opening 13, the tool clamping member 7 abuts against the flexible fiber push rods 2.

[0026] When the machining tool 53 needs to be replaced in the machining center, several flexible fiber lever rods 2 are provided at the opening 13 of the outer cover 12. The axial direction of the flexible fiber lever rods 2 is parallel to the frame of the surrounding frame 11. When the tool holder 7 swings along the opening 13 to the outside of the housing 1 through the propulsion mechanism 4, the surface of the tool holder 7 can contact the flexible fiber lever rods 2, so that the machining tool 53 carried by the tool holder 7 can clean the machining debris and impurities on the surface through the dense flexible fiber lever rods 2.

[0027] The specific structure of the adjusting turntable 5 is as Figure 4 shown. A rotatable adjusting turntable 5 is provided inside the base 3, and the number of tool holders 7 is several. The edge of the adjusting turntable 5 is a clamping outer disc 51, and several tool holders 7 are rotatably connected to the clamping outer disc 51. One end face of the adjusting turntable 5 close to the driving mechanism 6 is an adjusting inner disc 52, and several tooth grooves are provided on the adjusting inner disc 52.

[0028] In a specific solution, a driving mechanism 6 for driving the adjusting turntable 5 is provided on the back of the base 3. The driving mechanism 6 is composed of a stepping motor. The output end of the stepping motor is a driving gear 61, and the adjusting inner disc 52 meshes with the driving gear 61.

[0029] When the machining tool 53 needs to be replaced in the machining center, the driving gear 61 at the end is driven by the stepping motor to rotate quantitatively. At the same time, the tooth grooves on the periphery of the adjusting inner disc 52 can mesh with the driving gear 61 for transmission, so that the clamping outer disc 51 rotates following the adjusting inner disc 52, and the corresponding tool holder 7 moves to the opening 13 of the outer cover 12.

[0030] The specific structure of the tool holder 7 is as Figure 6 shown. A rotating pin 73 is provided in the middle of the tool holder 7, and the tool holder 7 is rotatably connected to the clamping outer disc 51 through the rotating pin 73.

[0031] One side of the tool holder 7 is a sleeve part 71. The sleeve part 71 is a cylindrical hollow structure and is used for inserting and fixing the machining tool 53. The other side of the tool holder 7 is a swing arm part 74. One end of the swing arm part 74 is fixedly connected to the sleeve part 71, and the other end of the swing arm part 74 is provided with a roller 72.

[0032] In a specific solution, the propulsion mechanism 4 is composed of a cylinder. One end of the cylinder is a push rod 41, and a plug-in block 42 matching the roller 72 is provided at the end of the push rod 41.

[0033] When it is necessary to replace the processing tool 53 in the machining center, first drive the adjustment turntable 5 through the drive mechanism 6 to move the corresponding tool holder 7 to the opening 13 of the outer cover 12. Then, through the propulsion mechanism 4 composed of a cylinder, extend the push rod 41 towards the opening 13 of the outer cover 12. At the same time, the insertion block 42 at the end of the push rod 41 can rotate the tool holder 7 along the rotation pin 73 to the outside of the housing 1 through the roller 72.

[0034] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention is disclosed above in a preferred embodiment, it is not intended to limit the present invention.
