Gauge for measurement of chamfer to datum level of three-pin shaft fork

Abstract

The invention discloses a gauge for measurement of a chamfer to a datum level of a three-pin shaft fork. The gauge comprises a base plate, a workpiece fixing seat, a dial indicator, a gasket and a centering cone shaft; the upper surface of the base plate is horizontally arranged, and stay bars are arranged on the base plate; the working piece fixing seat is arranged on the base plate; the dial indicator is fixed with the stay bars through a dial indicator fixing seat, and the measuring bar of the dial indicator is vertically arranged; the gasket is fixed with the dial indicator fixing seat through a rotating shaft, the first end and the second end of the gasket are respectively located on left and right sides of the axis of the rotating shaft, the first end of the gasket is abutted against the measuring head of the dial indicator, and the second end of the gasket is arranged in a manner of extending out of the dial indicator fixing seat to be abutted against the datum level of a workpiece clamped in the working piece fixing seat; the tip of the centering cone shaft is arranged downwardly, the centering cone shaft is fixed with the stray bars through a fastening ring and can move vertically relative to the stray bars, and the axis of the centering cone shaft is coincided with the workpiece clamped in the workpiece fixing seat. By the arrangement, the distance from the chamber to the datum level can be measured rapidly and accurately.

Description

technical field [0001] The invention relates to the field of workpiece measuring tools. More specifically, the present invention relates to a three-pin shaft fork measuring chamfer to datum plane measuring tool. Background technique [0002] As the key part of the constant velocity universal joint of the automobile, the tripod yoke plays the role of transmitting power in the car. The machining accuracy of the tripod yoke limits the precision of the universal joint and restricts the performance of the car. It is usually necessary to measure whether the distance from the chamfer of the three-pin shaft fork to the reference plane is accurate, but in the actual operation process, the measurement with a ruler is unstable and the measurement operation is complicated, which increases the user's measurement equipment requirements and the labor cost of the measurement personnel. , and the measurement efficiency cannot meet the requirements.
