Description

Technical Field

[0001] The utility model relates to a tungsten steel compound eye four-axis machining fixture. Background Art

[0002] When machining relatively hard workpieces (such as tungsten steel), the traditional method is to directly machine the workpiece using three axes. However, when machining the center position of the workpiece, there will be a point that cannot be machined at the center position of the workpiece. The reason is that when the spherical machining tool is at a 90-degree angle with the workpiece for machining, there is no cutting force when the center tangent point of the spherical machining tool tip cuts with the middle point of the workpiece shape. Therefore, there will be a point at the center of the circular shape of the workpiece that is not machined brightly and turns black. To solve the above problems, a rotating axis is added to the three-axis equipment to form a four-axis equipment. The workpiece is driven to rotate for machining by the rotating axis. When the workpiece rotates a certain angle, the spherical tool uses the side arc for machining, that is, there is a strong cutting force, so the above-mentioned blackening phenomenon will not occur. However, the rotating axis and the workpiece cannot be directly connected, so a machining fixture for connecting the workpiece and the rotating axis is designed. Content of the Utility Model
