Problems solved by technology

[0003] At present, when the production workshop conducts quality inspection on the differential, first place the differential case on the screw hole inspection platform, use a screwdriver to screw the screws into the threaded holes one by one, or screw them into the screw holes with a hand-held go-no-go gauge, and inspect After the completion, the screws or go-no-go gauges should be screwed out of the threaded holes one by one to check whether the screw holes of the differential case meet the relevant quality requirements; The laser transmitter of the manipulator first collects multiple points on the upper part of the inner ring surface of the flange connection, and the background computer analyzes the measurement data to calculate the flatness of the upper part of the inner ring surface; traditional detection methods require a large workload and low detection efficiency , prone to legacy, high error rate, quality inspectors also need to transfer the differential case to be tested on two inspection platforms, and when checking the flatness, it will also be placed incorrectly due to the specificity of the shape of the differential case At this time, there is an urgent need for a quality inspection equipment for the special shape of the differential case to solve the above problems

Abstract

The invention relates to differential case quality detection equipment. The equipment comprises a workbench, a supporting device which is installed on the workbench and used for bearing a workpiece, aflatness detection device which is used for detecting the flatness of the inner ring surface of the workpiece, and a thread detection device which is used for detecting the threads of screw holes ofthe workpiece. The supporting device is installed on the upper portion of the workbench. The flatness detection device is installed on the rear side of the supporting device. The thread detection device is installed on the left side of the supporting device. According to the invention, the workpiece is positioned and fixed through the supporting device; the threads of two screw holes are simultaneously detected at one time by the thread detection device; the flatness detection device carries out distance detection on multiple points which are annularly arranged on the inner ring surface of a flange connecting part, so as to judge whether the flatness of the inner ring surface of the flange connecting part meets related quality requirements or not; the workload is reduced; the detection efficiency and quality are improved; missing of thread detection of screw holes is avoided; the accuracy is high; and the adaptability is high.

Description

technical field [0001] The invention relates to the technical field of automatic detection equipment, in particular to a differential gear case quality detection equipment. Background technique [0002] The automobile differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. The ordinary differential is composed of planetary gears, planetary gear carriers (differential housings), side gears and other parts. The power of the engine enters the differential through the transmission shaft, directly drives the planetary wheel carrier, and then the planetary wheel drives the left and right half shafts to drive the left and right wheels respectively; the upper part of the differential case is provided with a flange connection and The lower part is equipped with a cylindrical support part. The quality requirements of the differential case are strict. Before assembly after the manufacturing process is completed, the qu...
