An online measuring device and method for measuring the end face flange of a cage

Abstract

An online measuring device and a measuring method for cage end flanges are provided. The device comprises a clamping tool and a measuring tool. The clamping tool comprises a base plate, a positioningplate, a long cylindrical pin and pressing plates. The pressing plates are installed on the base plate. The positioning plate is arranged in a window hole of a cage in a penetrating manner. The long cylindrical pin is fixed on the base plate, and abuts against the wall of the positioning plate. The measuring tool comprises a pressing ring, a measuring plate, short cylindrical pins and two cylindrical rollers. The short cylindrical pins are vertically connected with one end of the positioning plate. The two cylindrical rollers are arranged on the short cylindrical pins in a penetrating manner.The measuring plate vertically sleeves the positioning plate. The length of the measuring plate is the same with the maximum outer diameter of the cage. The pressing ring abuts against the outer sideof the measuring plate, and is tightly pressed on the outer side of the measuring plate by a screw I connected with one end of the positioning plate. The problem that online grinding and measuring cannot be realized by a surface grinder is solved. The purpose of fast and convenient online measurement is achieved. The production efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to an online measuring device and a measuring method for the flange of the end face of a cage. Background technique [0002] The peripheral surface of the cage is provided with several window holes, and the end face of the cage is provided with several equal parts of flanges. Generally, the end face of the cage is provided with four equal parts of flanges, such as figure 1 As shown, the distance H between the flange and the radial line passing through the center of the cage can be as small as 20.4 mm; at the same time, the angular position of the flange on the end face of the cage and the window hole of the cage has positional requirements. The two technical requirements determine that the cage cannot be directly clamped and ground on a surface grinder. A grinding device must be designed to ensure that although the H size can be measured by a three-coordinate measuring in...

AI Technical Summary

Problems solved by technology

These two technical requirements determine that the cage cannot be directly clamped and ground on the surface grinding machine, and the grinding device must be designed to ensure that although the H dimension can be measured with a three-coordinate measuring instrument, it cannot be measured online, and repeated disassembly, measurement, Re-clamping not only affects the machining accuracy of the H dimension of the cage, but also reduces production efficiency. Therefore, a fast and convenient online measurement method must be designed
