The key groove of the stepped shaft is one of the parts commonly used in machine manufacturing. In manufacturing a stepped shaft, it is necessary to machine a key groove on an end face of the shaft. The key slot is a critical part of positioning, orientation and torque transmission, and has strict size requirements. In this process, the distance between the end face and the key groove needs to be measured to ensure the processing quality.
In machining, a height gauge is generally used for measuring the height and depth of an object, but the axial dimension of a key slot is difficult to detect by using a conventional height gauge, and often the key slot is required to be checked by using a CMM three-coordinate measuring machine, which consumes a lot of time and affects the production efficiency. At present, no special tool is dedicated to measuring the axial distance of the key slot.
Disclosure of Invention
The utility model provides a tool for measuring the axial distance of the key slot of the stepped shaft workpiece, which can be simply matched with a height ruler to calculate the axial distance of the center of the key slot and realize rapid batch measurement of the axial distance of the key slot of the stepped shaft workpiece.
In order to achieve the above purpose, the technical scheme provided by the utility model is as follows: a frock for measuring stepped shaft work piece keyway axial distance, at least, including the frock body, the frock body is the cuboid, is close to the bottom of cuboid frock body head end and is equipped with the keyway locating piece with work piece keyway assorted, the keyway locating piece be the halfcylinder of bottom cutting, the length of halfcylinder equals work piece keyway length, the width of halfcylinder is the same with the width of keyway, the degree of depth of highly being less than the work piece keyway of halfcylinder, the terminal plane of cuboid frock body is terminal surface E, the keyway locating piece is placed in the keyway of work piece.
The length direction of the key groove positioning block is parallel to the end face E of the stepped shaft.
The distance from the center of the key groove positioning block to the end face E is A, the end face of the stepped shaft workpiece, which is close to the key groove, is end face C, and the distance from the end face C to the end face E is B.
Further, the axial distance of the key groove is D, and the axial distance d=b-ase:Sub>A from the center of the key groove to the end face of the stepped shaft workpiece close to the key groove is an end face C.
According to the technical scheme, the tool for measuring the axial distance of the key groove of the stepped shaft workpiece is matched with the key groove through the key groove positioning block on the tool body, the distance A between the center of the key groove positioning block and the end face E is calculated through the fact that the plane of the tail end of the tool body is the end face E, the axial distance D between the center of the key groove positioning block and the end face of the stepped shaft workpiece, which is close to the key groove, is the end face C is calculated, and whether the distance between the key groove and the end face is normal is determined through the calculation of the axial distance D:
according to the technical scheme, the surface of the tool body is used as a measuring reference, the center of the key groove positioning block is used as a determined standard quantity, the key groove detection block can be manufactured according to different widths, and the axial distance of the key groove of the stepped shaft workpiece can be obtained only through measuring by the height ruler, so that the axial distance of the key groove of the stepped shaft workpiece can be measured rapidly in batches, and the tool is high in universality and wide in applicability.
Moreover, because the tool has a simple structure, the key groove positioning block is a semicircular body, and the tool is high in matching degree with the key groove, convenient to assemble and disassemble, convenient to use and high in universality, the tool does not need to be checked by a CMM three-coordinate measuring instrument, the checking time is saved, the on-site checking at any time is realized, and the production efficiency is improved
