[0003] Because the special-shaped parts are large and small, in order to make the fixture adapt to parts of different sizes, after massive search, it was found that the Chinese utility model patent with the authorization announcement number CN219379840U in the prior art discloses "a special-shaped parts processing and fixing device", including a base, four supporting legs are fixedly installed at the bottom of the base, a first mounting plate is arranged on the top of the base, and second mounting plates are arranged on both sides of the top of the first mounting plate, and a special-shaped clamping device is arranged on the relatively close side of the second mounting plate. The special-shaped parts processing and fixing device realizes the installation of the second mounting plate through the arrangement of the first mounting plate, and the installation of the special-shaped clamping device is realized through the arrangement of the second mounting plate and the first motor.
