The invention relates to a detecting technique for a form and position tolerance of a motor base and particularly relates to a detecting device for a form and position tolerance of a motor base. The detecting device is used for solving the problems of low detection efficiency and high detection cost of the traditional detecting technique for the form and position tolerance of the motor base. The detecting device for the form and position tolerance of the motor base comprises a supporting part, a detecting part and a locating part, wherein the supporting part comprises a base and two brackets which are symmetrically mounted on the upper surface of the base; the detecting part comprises a rotating shaft; the locating part comprises four locating devices which are symmetrically mounted on the upper surface of the base; and each locating device comprises a rough locating base, a supporting base and an adjustable strut. Based on a brand new detecting structure for the form and position tolerance, the detecting device provided by the invention is used for solving the problems of low detection efficiency and high detection cost of the traditional detecting technique for the form and position tolerance of the motor base and is suitable for the detection for the form and position tolerance of the motor base.
Description
technical field [0001] The invention relates to a shape and position tolerance detection technology of a motor frame, in particular to a shape and position tolerance detection device of a motor frame. Background technique [0002] The frame is the main structural part of the motor, and its shape and position tolerance after processing directly affects the assembly and performance of the motor. The shape and position tolerance of the machine base mainly includes the coaxiality of the inner hole of the iron core to the center of the machine base, the perpendicularity of the end face to the center of the machine base, and the circular runout of the notch to the center of the machine base. At present, the coaxiality of the inner hole of the frame iron core to the center of the frame and the perpendicularity of the end surface to the center of the frame are mainly detected by a three-coordinate measuring machine. Sampling inspection is carried out; the circular runout of the not...
