Description

Technical Field

[0001] The utility model belongs to the technical field of fixtures, and particularly relates to a batch grinding fixture for hardware parts. Background Art

[0002] During the production of hardware parts, it is generally necessary to grind the blank parts, and corresponding grinding fixtures are required for grinding. A grinding fixture is a device specifically designed to fix and support the workpiece to maintain the stability and precise position of the workpiece during the grinding process. The grinding fixture can be a general type, suitable for workpieces of various shapes and sizes, or it can be a customized design, specifically for a certain type of workpiece or processing requirements.

[0003] Fixtures that are manually clamped and adjusted are inefficient in a batch production environment, lacking an automated or semi-automated clamping mechanism and being difficult to integrate with modern production lines. General-purpose grinding fixtures may not be able to well adapt to workpieces of different shapes and sizes, which leads to frequent replacement or adjustment of fixtures when facing diverse products in batch production, affecting efficiency. Therefore, we hope to design a grinding fixture with a new structure to solve this problem. Summary of the Utility Model
