Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a multi-angle indexing fixture for a four-axis machine tool. Background Technology

[0002] A four-axis machine tool is a CNC machine tool with four numerically controlled axes of motion. These four axes generally include three linear axes and one rotary axis. The three linear axes control the movement of the tool in the transverse, longitudinal, and vertical directions on the worktable, respectively, while the rotary axis controls the rotation of the tool or the worktable.

[0003] Currently, when machining parts using a four-axis machine tool, the parts are first clamped and fixed using a fixture. However, existing fixtures cannot adjust the position of the surface to be machined on the part. This leads to the need to adjust the position of the machining tool after machining one side of the part. At this point, the part must be free of obstructions to machine all other sides (excluding the clamped surface), which presents limitations. Therefore, a multi-angle indexing fixture for four-axis machine tools is invented. Utility Model Content
