Abstract

The invention provides a measuring tool and method for spline addendum circle diameter of disc gears, which solves the problem that the existing measuring accuracy of the addendum circle diameter of odd splines cannot meet the requirement of high precision tolerance. The inspection tool includes a frame, a positioning unit and a dial indicator; the upper surface of the frame is inclined, and a positioning platform is installed on the frame; the dial indicator and the positioning unit are respectively arranged on the upper and lower sides of the positioning platform; the positioning unit includes a V-shaped positioning block, spring, plug and positioning measuring ball; the V-shaped positioning block is installed on the frame body, and the V-shaped positioning groove of the V-shaped positioning block is close to the positioning platform. There is a stepped through hole in the V-shaped positioning block, and the positioning of the positioning measuring ball The main body is set in the large hole, and the measuring head of the positioning measuring ball protrudes out of the small hole to contact the tooth groove of the tested piece; the plug is set at the bottom of the first large hole; the spring is set in the first through hole , and is located between the plug and the positioning body; the dial gauge is installed on the frame through the locking piece; the center line of the dial gauge is collinear with the center line of the positioning ball.

Description

Technical field [0001] The present invention belongs to the gear tooth dome diameter measurement technology, specifically relates to a disc gear spline tooth dome diameter measuring fixture and method. Background [0002] as Figure 1 As shown, a disc gear, along the circumference of the cloth with an odd number of spline teeth 01, the processing process requires the hot after the spline tooth dome for fine machining, the diameter of the dome D 0 High precision requirements, dimensional tolerance requirements ≤ 0.026mm, because the outer spline is odd teeth (usually the number of teeth is 45), the current measurement of the diameter of the odd tooth spline tooth dome diameter mainly has a three-point positioning measurement method, but the measurement accuracy can not meet the high-precision tolerance requirements of spline shaft parts. Contents of the Invention [0003] In order to solve the existing technical problems of measuring the diameter of the odd spline tooth dome dia...
