Abstract

The invention relates to a rapid detection tool for a large taper hole. The detection tool comprises a detection tool pedestal, wherein the detection tool pedestal is provided with an adjusting arm and a measuring arm which are vertically distributed; the measuring arm is provided with dial indicators for measuring angular error of the taper hole; and the adjusting arm is provided with adjusting screws for demodulating the dial indicators. In the detection tool, an instrument support is provided with the measuring arm; an adjusting support is provided with the adjusting arm; the adjusting arm is provided with a first adjusting screw and a second adjusting screw; the measuring arm is provided with a first detection dial indicator and a second detection dial indicator; the first detection dial indicator and the second detection dial indicator perform zero reset through the first adjusting screw and the second adjusting screw; the aperture and the taper of the large taper hole can be rapidly measured according to tape error values of the first detection dial indicator and the second detection dial indicator in comparison with the standard taper of a standard taper ring gauge; the detection is convenient and fast, and the working efficiency is greatly improved; and the detection tool has a wide application range, no sliding friction, long life and a simple structure and is lower in manufacturing cost.

Description

technical field [0001] The invention relates to a tapered hole inspection tool, in particular to a rapid detection large tapered hole inspection tool, which belongs to the technical field of mechanical inspection tools. Background technique [0002] For tapered hole parts, when the hole diameter is less than f150, the inspection tool usually adopts a custom-made standard taper plug gauge, and the coloring method is used for inspection to check whether the contact with the large end of the tapered surface is greater than 70%. Then mark the diameter limit line on the standard plug gauge to detect the size of the taper hole. When the aperture is larger than f150, the above method will not work. The main reason is that the weight of the inspection tool is too large, and the contact area with the workpiece is too large, which makes the rotation difficult and the phenomenon of seizure occurs. Therefore, when detecting such large tapered holes, three-coordinate detection is genera...
