Description

Technical Field

[0001] The present application relates to the technical field of workpiece positioning, and in particular to a workpiece positioning device. Background Art

[0002] Mechanical processing refers to the process of processing a workpiece through mechanical processing equipment, which usually includes CNC processing, milling, turning, drilling, grinding, cutting and other processes. It can be used to process metal, plastic, wood and other materials to make various parts and products. During the mechanical processing, the workpiece to be processed needs to be positioned by a positioning device to keep it in a stable state during processing. However, since different mechanical parts have different shapes and sizes, when the existing positioning device fixes the mechanical parts, some workpieces are affected by the special shape during positioning, and multiple surfaces cannot be positioned by the positioning device at the same time. This may cause a certain position offset of the workpiece during the processing process, which in turn has a certain impact on the overall accuracy of the workpiece processing and reduces the overall processing efficiency of the mechanical parts. Therefore, this technical solution proposes a workpiece positioning device.

At the same time, the fixed angle of the clamping device makes it inconvenient to adjust the angle of the clamping device during work. Utility Model Content
