Abstract
Description
Technical Field
[0001] The utility model relates to a detection device for shaft parts, in particular to a top calibration tool for a double-meshing instrument. Background Art
[0002] The drive shaft is a moving part that rotates at high speed in the machine. It is a component with relatively strict error requirements. Shaft parts need to maintain their own stability during high-speed movement. One of them is to detect the outer diameter of its axial direction, that is, whether the runout value of the shaft outer diameter is within a reasonable tolerance range. Uneven outer diameters will cause the shaft parts to vibrate during movement, and the overall working condition of the machine will also be unstable. In the existing technology, there are four main shaft detection methods: visual inspection, measuring tool inspection, optical inspection and image inspection. Among them, visual inspection is simple and intuitive, but it is only a rough inspection and the accuracy is not high. Optical inspection and image inspection are relatively high, but the inspection equipment is relatively expensive. Measuring tool inspection uses various measuring tools, such as calipers, outside micrometers, etc. This method has high accuracy, but not only requires professional and technical personnel to operate, but also has low detection efficiency.

In this embodiment, the rotating top device 3 is slidably provided on the column 2. The base 4 is provided on the base platform 1 directly below the rotating top device 3. In this embodiment, a bearing seat is provided in the base 4. The shaft to be tested is vertically clamped between the base 4 and the rotating top device 3, with its bottom provided on the bearing seat and its top pressed by the top clamping device, and rotated synchronously by the rotating top device 3.
