Detection tool for measuring position accuracy of shaft outer wall oblique hole

Abstract

The invention discloses a detection tool for measuring position accuracy of a shaft outer wall oblique hole. The detection tool comprises a base, a linear rail, a tail base, a pin base, a sliding plate, a right bearing, an edge cutting pin, a gauge frame, a clock gauge and a left bearing, wherein the sliding plate is matched with the oblique pin base to move left and right along the linear rail, so that an oblique hole in a conical shaft section of a workpiece can be aligned; the edge cutting pin is fixedly connected with the left end surface of the sliding plate; the vertical edge cutting pinis mounted in a manner of enabling the cut edge to be arranged outwards; the gauge frame is arranged on one side of the linear rail; the upper end of the gauge frame is used for clamping the clock gauge with an upward gauge disc; a gauge head end of the clock gauge faces rightwards and is in contact with the plane of the edge cutting pin to form a positioning and measuring mechanism. The detection tool is simple in structure and high in detection accuracy, is capable of efficiently detecting the position accuracy of the shaft outer wall oblique hole, and is especially applied to on-line detection of production site.

Description

technical field [0001] The invention belongs to the technical field of length measuring and checking tools, in particular, the invention relates to a checking tool for measuring the position size between shaft structures, especially a checking tool for measuring the position accuracy of oblique holes on the outer wall of the shaft. Background technique [0002] The transmission shaft is a common mechanical part. Since the structural elements of the shaft are relatively simple, it is easy to realize cutting. Due to the complex transmission relationship, the automotive gearbox is usually equipped with multiple transmission shafts with high precision requirements. One of the shaft ends is a tapered shaft section, and a circular through hole perpendicular to the tapered shaft generatrix is ​​provided on the tapered shaft section. The hole is an oblique hole relative to the axis, and the oblique hole has a position accuracy of ±0.03mm from the design dimension of the shoulder at ...
