Abstract

The utility model discloses a form and position deviation detection device for a machine tool processing hole. The device comprises a contact, a round head screw, a rocker, an alignment frame, a dial indicator, a supporting rod, a sunk screw, a fastening screw, a sliding block and a slotting conical end set screw. According to the proportion of the tip of the contact and the length of the force arm from the lower end of the dial indicator to the slotting conical end set screw, the part hole wall shape and position deviation range is calculated, and the part hole wall shape and position deviation value is reflected on the dial indicator through the device. After a part is drilled, the device is clamped on a machine tool spindle, a ball at the tip of a contact is in contact with the surface of the hole wall of the part, the machine tool spindle is slowly rotated and axially fed, the position of a pointer of the dial indicator is observed, and when the position of the pointer is within the marked range, it is proved that the perpendicularity and the coaxiality of the hole machined by the part are within the permissible range. And when the position of the pointer exceeds the marked range, the part hole needs to be subjected to supplementary machining.
