Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a machine for removing broken taps which can be quickly centered. Background Art

[0002] In the field of mechanical processing, tapping holes with taps is a common processing process. However, during the tapping process, the tap is easily broken in the hole due to the tapping technique or the hardness of the material. At this time, when the tail of the tap remains outside the hole, the tail of the broken tap can be clamped by a tool to twist and remove it. However, when the tap breaks deeper, it is necessary to insert the tool into the gap between the tap and the hole to reverse and remove it. However, during the removal process, due to the inconvenience of lighting in the hole, it is difficult to align the removal tool when inserting it. Eccentricity will cause the insertion to be crooked or the insertion depth to be insufficient, which will directly affect the removal of the tap. Once the removal tool breaks again in the gap between the tap and the hole, it will make the broken tap more difficult to remove. Utility Model Content
