Problems solved by technology
As the output of this workpiece continues to increase, the defects of the optical method itself are cumbersome and inefficient, especially for the detection of the inner cavity cone, which can only be detected after the tapered tube is symmetrically cut along the axis. , this method is obviously not suitable for batch detection, therefore, it is necessary to develop a detection device that can meet the batch detection requirements of such conical tubes

The invention discloses a comprehensive detection device for the internal conical face and the external conical face of a cone-shaped tube. The comprehensive detection device comprises a rack, a driving and limiting mechanism, an external cone detecting mechanism and an internal cone detecting mechanism. High-precision repeated location of an upper locating column is achieved, and an adjustable limiting column is used for controlling the axial in-place position of the upper locating column. The internal cone detecting mechanism and the external cone detecting mechanism are each provided with a guiding drill bush and a pressure spring. By means of the guiding drill brushes, the axis coaxiality of the upper locating column and an inner cavity locating shaft can be smaller than 0.01 mm, and then the coaxiality of measurement parts of the internal conical face and external conical face is ensured; due to the pressure springs, after the upper locating column and the inner cavity locating shaft are in place, opposite axial acting force continues to be exerted, so that it is ensured that the measurement parts are completely attached to the internal conical face and the external conical face of the cone-shaped tube.
Description
technical field [0001] The invention belongs to a precision detection device, in particular to a comprehensive detection device for the inner and outer tapered surfaces of a tapered tube. Background technique [0002] Small-diameter conical tubes are generally formed by spinning, and whether the position of the conical surface meets the design requirements will directly affect the functional characteristics of such workpieces. For the detection of such workpieces, the optical method, that is, the universal tool microscope, has been used for detection. As the output of this workpiece continues to increase, the defects of the optical method itself are cumbersome and inefficient, especially for the detection of the inner cavity cone, which can only be detected after the tapered tube is symmetrically cut along the axis. , this method is obviously not suitable for batch detection, therefore, it is necessary to develop a detection device that can meet the requirements of batch de...
