Abstract
The invention discloses a detection tool for detecting the geometric accuracy of the spindle axis of a precision numerical control machine tool. The detection tool comprises a transition connector, a supporting plate, a locking nut and a dial indicator. The surface of the supporting plate is provided with two kidney-shaped grooves. One end of the supporting plate is connected with the dial indicator. One end of the transition connector penetrates through the kidney-shaped grooves in the supporting plate and is in threaded connection with the locking nut, and therefore fixed connection between the transition connector and the supporting plate is achieved. According to a detection method of the detection tool for detecting the geometric accuracy of the spindle axis of the precision numerical control machine tool, the dial indicator is not directly mounted on the end face of a spindle, an indicator swing radius detection record is adjusted through the detection tool. The detection tool is simple in structure and convenient to use, can be designed for different equipment in a targeted mode under the condition that all requirements are met, and is portable, easy to mount and high in accuracy of obtained data when being used for detecting the geometric accuracy of the spindle axis of the precision numerical control machine tool; and all possibilities that the dial indicator slips in the detection process are avoided through fixed clamping, and the indicator swing radius can be automatically adjusted.
