The utility model belongs to the technical field of detection equipment, and particularly relates to a
die casting threaded hole tooth gauge detection module which comprises a supporting plate and a thread detection mechanism, and the thread detection mechanism comprises a
servo motor, an upper main shaft, an upper
universal joint, a plum blossom shaft sleeve, a plum blossom shaft, a lower
universal joint, a middle connecting shaft, a middle shaft sleeve, a flexible shaft, a tooth gauge shaft seat, a tooth gauge shaft seat sleeve and a tooth gauge. The
servo motor is fixed to the rear side of the supporting plate, the upper main shaft is rotatably installed on the supporting plate and is in transmission connection with the
servo motor, the plum-blossom-shaped shaft sleeve is connected with the upper main shaft through the upper
universal joint, the plum-blossom-shaped shaft is inserted into the plum-blossom-shaped shaft sleeve to be matched with the plum-blossom-shaped shaft sleeve, and the middle connecting shaft is connected with the bottom end of the plum-blossom-shaped shaft through the lower universal joint and sleeved with the middle shaft sleeve. The tooth gauge shaft seat is connected with the bottom end of the middle connecting shaft through the flexible shaft, the tooth gauge shaft seat is sleeved with the tooth gauge shaft seat sleeve, and the tooth gauge is installed on the tooth gauge shaft seat. According to the utility model, part of non-vertical threaded holes can still be automatically detected, manual work is replaced, and the production efficiency is higher.
