Problems solved by technology

[0007] The embodiment of the present invention provides a device and method for detecting the taper of tapered bolts. A standard angle block and a dial indicator are used. During the movement of the standard angle block driven by the base, the taper is calculated by reading the dial gauge. The taper and taper length of the bolt solve the problems of low detection efficiency and low accuracy in the prior art

Abstract

The invention relates to a device and method for detecting taper of a conical bolt. The device comprises a horizontal ruler workbench, a base, a standard angle block and a dial indicator mounting frame; the base is movably arranged on the horizontal ruler workbench, a stop position adjusting structure is arranged on one side of the base, the dial indicator is arranged on the upper portion of the base through the dial indicator mounting frame, wherein the upper surface of the standard angle block is an inclined surface, the angle of the inclined surface is the same as the theoretical taper of the detected conical bolt; during detection, the detected bolt is placed on the upper end surface of the base through the standard angle block, the large-diameter end of the detected bolt is placed towards the stop position adjusting structure; the stop position adjusting structure is used for limiting the horizontal position of the large-diameter end; and the inclined surface of the standard angleblock is inclined towards the stop position adjusting structure, so that the center axis of the detected conical bolt is kept horizontal.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a device and method for detecting the taper of tapered bolts. Background technique [0002] In order to meet the requirements of long life, advanced aircraft usually adopt interference connection technology to improve fatigue strength. The fastening connection system used needs to have high dimensional accuracy to ensure the requirements of connection assembly. In order to achieve the uniformity of interference connection, tapered Bolt fastening system. In order to meet the precise fit of the interference connection, it is necessary to detect the taper of the tapered bolt. There are correspondingly high requirements for the detection technology to meet the reliability of the size detection, and it is necessary to improve the detection efficiency for large-scale detection. [0003] At present, the detection of the taper of tapered bolts is usually detected by the projection met...
