Testing device for key dimension of automotive hub shaft

Abstract

The invention relates to a testing device for key dimension of an automotive hub shaft, wherein the testing device belongs to the mechanical field. The whole testing device is mainly composed of a frame, a feeding part and a testing part. The feeding part and the testing part are mounted on the supporting plate of the frame and are connected through a worktable. The worktable is a six-station worktable and is driven by a servo motor. High convenience and relatively high precision in positioning are realized. A to-be-tested piece is fed to different stations for testing. The feeding mechanism, a go gauge testing mechanism, a no-go gauge testing mechanism, an outer diameter testing mechanism and two material outlet mechanisms are successively arranged right above six stations of the worktable. A laser sensor is arranged at a material discharging outlet. When a foreign matter enters the sensor area, operation of the testing device is stopped, thereby preventing safety accidents. The testing device has advantages of realizing simultaneous operation of multiple devices, greatly reducing time required in testing, improving testing efficiency, realizing automatic material feeding and material discharging of the to-be-tested piece, realizing high automation degree and reducing enterprise input in manpower and equipment.

Description

Technical field: [0001] The invention relates to the mechanical field, in particular to a device for detecting key dimensions of an automobile wheel hub shaft. Background technique: [0002] Due to the high requirements for the accuracy of the internal thread and the accuracy of the outer diameter of the automobile hub shaft during the automobile assembly process, the automobile hub shaft manufacturer needs to test the accuracy of the outer diameter and the accuracy of the internal thread after the processing is completed to determine whether the product is qualified. If it is unqualified, it means that the workpiece is a defective product and cannot be used normally. At present, the internal thread detection and outer diameter detection methods of the workpiece have been greatly improved compared with previous years: the most common method in the past few years is manual detection, and the inspector manually uses the detection tool to check the internal thread of the workpi...

Problems solved by technology

[0002] Due to the high requirements for the accuracy of the internal thread and the accuracy of the outer diameter of the automobile hub shaft during the automobile assembly process, the automobile hub shaft manufacturer needs to test the accuracy of the outer diameter and the accuracy of the internal thread after the processing is completed to determine whether the product is qualified. If it is unqualified, it means that the workpiece is a defective product and cannot be used normally

At present, the internal thread detection and outer diameter detection methods of the workpiece have been greatly improved compared with previous years: the most common method in the past few years is manual detection, and the inspector manually uses the detection tool to check the internal thread of the workpiece. It is inconvenient, time-consuming and labor-intensive to measure the outer diameter, and the tester repeats the test for a long time, which cannot guarantee the accuracy of the test; at present, some relatively large processing enterprises have begun to use automatic detection equipment, but These devices can only detect the accuracy of the internal thread or the accuracy of the outer diameter separately. To detect these two items, two detection devices are required, which requires high costs, requires a lot of labor, and has low work efficiency.
