Positioning tool for three-coordinate detection of cylinder parts

Abstract

The invention discloses a positioning tool for three-coordinate detection of cylinder parts, and aims to provide a positioning detection tool which is high in universality and accurate and reliable inpositioning, and the positioning detection tool is realized through the following technical scheme: a transverse dovetail groove 8 is provided with a movable side plate, and a longitudinal dovetail groove is provided with a movable mandrel; a rotating block moves up and down through cooperation of a hole shaft, and two T-shaped head bolts penetrate through through holes in the roots of two V-shaped blocks respectively to fix the V-shaped blocks. The barrel type measured workpiece moves to the rear end of the V-shaped block in the axial direction of the barrel type measured workpiece; the elastic piece is attached to the movable side plate; the movable core shaft moves to a position corresponding to a horizontal plane needing to be leveled of the barrel type measured workpiece along the longitudinal dovetail groove; and the rotating block moves along the axis of the movable mandrel, horizontally rotates around the axis of the movable mandrel and moves downwards along the axis of the movable mandrel to finish leveling of the horizontal plane of the measured workpiece, horizontally rotates around the axis of the movable mandrel to transfer the rotating block away, and moves downwardsto the bottom plate along the axis of the movable mandrel.

Description

technical field [0001] The invention relates to a positioning tool mainly used for three-coordinate detection and detection of cylinder-like parts, in particular to a positioning tool for three-coordinate detection and detection of cylinder-type parts for automatic detection of aviation cylinder-type workpieces. Background technique [0002] At present, due to the large number of cylindrical workpieces, large batches of parts with the same diameter or different diameters, and large changes in detection dimensions, especially aviation cylindrical workpieces, the installation between the holes of cylindrical workpieces is realized during measurement. The location requirements are high. In order to ensure the final assembly requirements of the cylindrical workpiece, it is necessary to carry out 100% three-coordinate detection of the cylindrical workpiece. When the three-coordinate program automatically detects the size of the part, there are requirements for the size and mutual...
