Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece detection equipment, and in particular relates to an automatic detection equipment for circular runout of shaft-type workpieces. Background Art

[0002] The traditional method of detecting the circular runout of shaft workpieces is to manually fix the two ends of the workpiece, rotate the outer ring of the workpiece by hand, and observe the reading of the micrometer at the same time to achieve circular runout detection. However, this method is time-consuming and labor-intensive, with high labor costs, poor measurement accuracy and low efficiency.

[0003] In the prior art, a patent document with publication number CN 110132196 A discloses an automatic detection device for the circular runout of a wheel rim, comprising a transport device for transporting a wheel hub, a workbench for placing the wheel hub, a transport device for transporting the wheel hub to the workbench, a clamping device for clamping the wheel hub, a positioning device for positioning the wheel hub, and a detection device for detecting the circular runout and radial circular runout of the wheel rim end, wherein the positioning device comprises a positioning wheel, a positioning shaft having several models and an inner end of the positioning shaft being mounted on the positioning wheel through a bearing, a positioning boss being provided at one end of the positioning shaft, a transmission hole being provided at the other end of the positioning shaft, the transmission hole being transmitted in cooperation with the transmission shaft, a plurality of adjustment seats being provided on the side wall of the positioning wheel, four sets of top screws being evenly distributed on the side wall of the adjustment seat, fixing nuts being provided on the top screws, a driving motor being provided in the positioning box, and a positioning cylinder being fixedly connected to the upper end of the column. The above scheme can automatically detect the end circular runout and radial circular runout of the rim at the same time, and transport the hub from the transportation device to the workbench. The transportation device and the handling device are replaced by employees' handling. The transportation device and the handling device are independently set, which not only requires control and coordination by the control mechanism, but also the handling device needs to accurately grasp and transport the workpiece. It has high manufacturing precision and many supporting sensing equipment, so the manufacturing cost and the use cost are relatively high, and it is not suitable for automatic detection of circular runout of shaft workpieces. Since the process of transporting the workpiece is added, a longer waiting time for transporting the workpiece is required, which reduces the efficiency of detection. Summary of the invention
