This application relates to the field of mechanical parts processing technology, specifically disclosing a grinding device for excavator parts, including a main body and a grinding robotic arm. The grinding robotic arm is provided on the outer surface of the main body. The grinding robotic arm includes a robotic arm, a drive motor, and a grinding disc. The output end of the drive motor is sleeved with the grinding disc. This invention can clean the worktable in a timely manner through a dust removal component, preventing debris from affecting subsequent grinding work, ensuring that the parts are placed stably and positioned accurately. Keeping the worktable clean reduces the flying of debris and dust, improves the working environment, and protects the respiratory health of operators. The clamping component can stably clamp the parts, and can promptly issue an alarm when the parts deviate in the clamp, preventing unqualified products from entering the market. In addition, it can detect the parallelism of the clamping arm and issue an alarm when the clamping arm tilts, preventing uneven distribution of clamping force during grinding.
