Description

Technical Field

[0001] The utility model relates to the field of milling, in particular to a tool setting device for milling keyways. Background Technique

[0002] Milling is a machining method that uses a milling cutter as a tool to machine the surface of an object. There are horizontal milling machines, vertical milling machines, gantry milling machines, profiling milling machines, universal milling machines and bar milling machines. Milling refers to using a rotating multi-edge tool to cut the workpiece, which is a high-efficiency machining method. During operation, the tool rotates (as the main motion), and the workpiece moves (as the feed motion). The workpiece can also be fixed, but in this case, the rotating tool must also move (completing both the main motion and the feed motion simultaneously). The machine tools used for milling are horizontal milling machines or vertical milling machines.

[0003] At the current stage, when milling a keyway on a workpiece, it is necessary to bring the workpiece close to the tool and then perform the milling operation. Currently, during the tool setting process, an electric push rod is generally used to push for tool setting. In this way, the accuracy of cutting the keyway on the workpiece is poor and it is not conducive to current use. Therefore, we propose a tool setting device for milling keyways to solve the above problems. Content of the Utility Model
