The invention relates to the technical field of electromechanical equipment, and discloses component flatness detection equipment for electromechanical equipment manufacturing, and the equipment comprises a shell, the inner wall of the shell is movably connected with a rotating shaft, the front surface of the rotating shaft is fixedly connected with a fixed ring, and the outer side of the fixed ring is fixedly connected with a connecting rod. A knocking block is fixedly connected to the outer side of the connecting rod, a friction ring is fixedly connected to the outer side of the rotating shaft, a second spring is fixedly connected to the inner wall, close to the top of the connecting rod, of the shell, and a first spring is fixedly connected to the inner wall, close to the bottom of the connecting rod, of the shell. According to the component flatness detection equipment for electromechanical equipment manufacturing, the knocking block drives the tuning fork to vibrate, manual judgment is avoided, judgment errors are prevented, time and labor are saved, the number of defective components is reduced, influence on electromechanical equipment manufacturing is avoided, the percent of pass of products during electromechanical equipment manufacturing is increased, resources are saved, and the production efficiency of electromechanical equipment manufacturing is improved.
