The invention discloses a tapping machine and a tapping method. The tapping machine comprises a triaxial movable platform, and a first Z-axis driving arm is arranged in the Z-axis direction of the triaxial movable platform. The first Z-axis driving arm drives a first sliding block to move in the Z-axis direction. A second Z-axis driving arm is arranged on the first sliding block, and the second Z-axis driving arm drives a second sliding block to move in the Z-axis direction. A tapping device is arranged on the second sliding block, and the tapping device is connected with a tapping tool. A pushing force sensor is arranged on the second sliding block and used for monitoring tension generated on the second sliding block when the tapping tool advances and feeding back tension information to acontroller, and the controller controls a second Z-axis driving arm to move the second sliding block to offset the tension. According to the structure of the tapping machine, the method that the tapping tool taps into a workpiece by itself is adopted, pressure on the tapping tool is reduced, and the tension of the tapping tool on the tail is reduced; and the tapping tool approximately simulates tapping in a weightless state, and the service life of the tapping tool is effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of machine tool tapping, in particular to a tapping machine and a tapping method. Background technique [0002] Existing machine tool tapping uses a three-axis mobile platform as a moving standard. The tapping tool is set on the Z axis and is pushed down to the workpiece by the force arm, and then the force arm pushes the tapping tool / drill forcefully. , so that threads are produced on the workpiece, such as the structure of the notification number CN206578538U. [0003] If at this time the resistance during the work advance suddenly increases and the work advance slows down, the force arm will break the tapping knife, causing the workpiece to be scrapped. [0004] Therefore, we want to study a kind of tapping knife that can advance the workpiece by self-tapping to reduce pressure and push, and can also adjust the structure according to the change of resistance during tapping.
