Description

Technical Field

[0001] The utility model relates to the field of tooling fixtures, in particular to a metal tooling fixture with anti-slip and anti-damage functions. Background Art

[0002] A fixture is a process device used to quickly fasten the workpiece during processing so that the machine tool, tool and workpiece maintain the correct relative position. In other words, tooling fixtures are indispensable components of mechanical processing. Driven by the development of machine tool technology towards high speed, high efficiency, precision, composite, intelligent and environmentally friendly directions, fixture technology is developing towards high precision, high efficiency, modularity, combination, universality and economy.

[0003] Metal parts usually refer to parts or components made of metal materials. Metal parts are widely used in various industrial and manufacturing fields. Their characteristics include high strength, wear resistance, conductivity and good processing performance. When processing workpieces on machine tools, in order to make the surface of the workpiece meet the technical requirements such as size, geometry and relative position accuracy with other surfaces specified in the drawings, the workpiece must be installed and clamped before processing. However, the current tooling and fixtures mostly clamp the workpiece on both sides when clamping the workpiece. When the machine tool processes the metal part in the Y-axis direction, the metal part is very easy to slide and deviate in the Y-axis direction. For this reason, we propose a metal part tooling and fixture with anti-slip and anti-damage functions to solve the above problems. Utility Model Content
