The pneumatic cylinder 6 drives the transmission component 404 to drive the static electricity removal component 402 to slide inside the milling hole positioning disk 401. The cleaning component 405 is arranged inside the milling hole positioning disk 401. The cleaning component 405 cleans the waste chips after static electricity removal, and the bottom of the waste chip discharge tray 301 is connected to the negative pressure machine.

The annular static rod 4022 is connected to the electrostatic device 4021 via a connecting wire, and the connecting wire can be hidden in the wall of the milling hole positioning disk 401. The electrostatic device 4021 energizes the annular static rod 4022 so that the air mass generated by the annular static rod 4022 contacts the waste chips, thereby performing a static elimination operation on the waste chips. Here, the electrostatic device 4021 21 belongs to the existing equipment, which provides power to the annular electrostatic rod 4022 through the electrostatic device 4021. The annular electrostatic rod 4022 can generate a large number of air masses with positive and negative charges, which can neutralize the charges on objects passing through its ion radiation zone. When the surface of the waste chips is negatively charged, it will attract the positive charges in the radiation zone. When the surface of the waste chips is positively charged, it will attract the negative charges in the radiation zone, thereby neutralizing the static electricity on the surface of the waste chips and achieving the purpose of eliminating static electricity. The air masses generated by the annular electrostatic rod 4022 come into contact with the waste chips to perform static electricity removal operations on the waste chips.

[0037] The transmission assembly 404 includes a driving plate 4041, a connecting rod 4042 and a mounting plate 4043. The output end of the pneumatic cylinder 6 is fixedly connected to the driving plate 4041. The top of the driving plate 4041 is fixedly connected to multiple groups of connecting rods 4042.

The peripheral wall is used to facilitate the static electricity removal of the waste chips adhered to the support base 5 and the outer peripheral wall of the milling hole positioning disk 401, and the adhered waste chips can be completely de-staticized. It should be noted that multiple groups of annular electrostatic rods 4022 are connected to the transmission component 404, and then with the cooperation of the transmission component 404, multiple groups of annular electrostatic rods 4022 can be driven together to slide inside the milling hole positioning disk 401 respectively, so that the annular electrostatic rods 4022 can remove the static electricity of the waste chips adhered to the milling hole positioning disk 401 and the entire surface of the support base 5, so that the waste chips fall to the bottom of the waste chip discharge tray 301, so as to facilitate the subsequent cleaning of the waste chips.

[0038] The driving assembly 406 includes a transmission gear ring 4061, a driving gear 4062, a transmission shaft 4063 and a driving motor 4064.

Inside, the fallen waste chips are scraped toward the waste chip discharge pipe 4031 so that the waste chips can be sucked out of the inside of the milling hole positioning disk 401 by the negative pressure fan, thereby realizing the waste chip cleaning operation. The sealing plate 4051 can also seal the hole for installing the suction cup 501 at the support base 5, thereby preventing the waste chips generated during the cutting process from falling downward through the hole and escaping from the inside of the milling hole positioning disk 401, making it difficult to clean. At the same time, the installation of the sealing plate 4051 does not affect the suction cup 501, and the suction cup 501 inside the support base 5 can also adsorb the cutting part of the workpiece, thereby preventing the workpiece from flying out at the moment of cutting and causing harm to the staff.

After it is pushed into place, the driving cylinder 3024 drives the upper pressing plate and the lower pressing plate to descend together, driving the mold bracket 4 to move downward, and the mold bracket 4 is placed on the mounting bracket 3. The bottom of the tire holder 4 contacts with the lower pressure plate, and as the upper pressure plate and the lower pressure plate continue to descend, the tire holder 4 is pressed against the mounting bracket 3. At this time, the upper pressure plate contacts the top of the tire holder 4. When the tire holder 4 is installed, the guide wheel 3023 can be used to guide the tire holder 4. The stopper 3021 is set on both sides of the front end of the mounting bracket 3. Through the cooperation of the pin hole 7 and the first positioning pin shaft 3025, the tire holder 4 and the mounting bracket 3 can be limited and positioned. The ball 3027 and the guide wheel 3023 facilitate pushing the tire holder 4 into the mounting bracket 3. At the same time, the guide wheel 3023 can guide the tire holder 4. The stopper 3021 can block the tire holder 4 when the tire holder 4 is pushed into the mounting bracket 3 to prevent the tire holder 4 from slipping out of the mounting bracket 3. The tire holder 4 is pushed into the mounting bracket 3 by an external mechanism. The above components realize the positioning and fixing operation of the tire holder 4.

[0041] Working principle:

[0042] Before use, the jig bracket 4 is first positioned and fixed on the top of the mounting bracket 3, and then the automobile decorative panel that needs to be milled is positioned and fixed through the suction cup 501 on the jig bracket 4. At this time, the decorative panel is located on the top of the milling hole positioning plate 401, and the suction cup 501 installed inside the milling hole positioning plate 401 can be adsorbed and fixed to the part that needs to be milled, so as to facilitate the milling robot 1 to perform milling operations on the automobile decorative panel;

[0043] During the milling process, the milling manipulator 1 first drives the milling head 2 to move, and the milling head 2 makes a circular motion along the periphery of the support base 5 so as to perform a milling operation on the decorative plate. During the milling process, a certain amount of waste chips will be generated, and the generated waste chips will adhere to the surface of the milling positioning plate 401 and the support base 5. The annular electrostatic rod 4022 installed inside the milling positioning plate 401 can remove static electricity from the adhered waste chips, so as to prevent the waste chips from generating static electricity and adhering to the surface of the milling positioning plate 401 and the support base 5, making it difficult to clean.

[0044] At the same time, the transmission component 404 can drive the internal annular electrostatic rod 4022 to slide on the inner wall of the milling hole positioning disk 401, so that the annular electrostatic rod 4022 can contact the milling hole positioning disk 401 and the entire outer wall of the support base 5, so as to perform static electricity removal operation on the adhered waste chips, so that the adhered waste chips fall into the inside of the milling hole positioning disk 401, and by starting the drive component 406, the drive component 406 drives the cleaning scraper 4052 to rotate inside the milling hole positioning disk 401, and scrapes the waste chips to the waste chip discharge pipe 4031, so that the negative pressure fan can discharge the waste chips through the hose, connecting pipe 4033, through pipe 4032 and the inside of the milling hole positioning disk 401.
