Description

Technical Field

[0002] Workpiece runout is a common problem during grinding, which may lead to inaccurate shape and size of the workpiece, thus affecting the quality of the final product. In order to solve this problem, a detection mechanism is designed to monitor in real time whether the workpiece is in a non-running state. Through such a detection mechanism, the grinding machine can be stopped in time when the workpiece is in a runout state, thereby avoiding the production of unqualified products. This detection not only improves the accuracy and consistency of the workpiece, but also reduces the output rate of defective products, thereby improving production efficiency and product quality.

The workpiece runout detection structure for a grinder is connected to the grinder equipment. The position of the workpiece clamped laterally is adjusted by slidingly connecting a fixed plate. At the same time, multiple movements in the X, Y and Z directions are realized by using a longitudinal slide rail and a vertical slide bar. In conjunction with a runout detector, the detection operation of different positions of the workpiece is realized, thereby improving efficiency.

[0004] However, there are still some shortcomings that need to be optimized, as follows: In the workpiece runout detection structure for the grinder, the runout detector is mainly installed through a vertical slide bar and a detection seat, resulting in that only radial runout detection can be performed on the workpiece in the vertical direction, and axial runout detection cannot be performed on the workpiece in the axial direction, which is not conducive to improving the accuracy of the workpiece.
