Problems solved by technology

The method currently used is: use a small punch to slowly punch out the broken wire tap, or break the wire tap into pieces, and use a hook to take out the broken wire tap; large taps can be stacked by electric welding, or the tap can be crushed with flame After burning and annealing, use an electric drill to remove it, or use electric sparks to etch it. The above methods are time-consuming and labor-intensive, and even destroy the integrity of the processed thread

Abstract

The invention discloses a broken screw tap taking-out device and a taking-out method, and belongs to the technical field of thread machining. The broken screw tap taking-out device comprises a taking-out body, a clamping head is manufactured at the front end of the taking-out device body, the clamping head is provided with a plurality of clamping claws corresponding to a chip pocket of a screw tap, and a handle is fixed to the rear end of the taking-out device body. The taking-out method comprises the steps that the clamping head is inserted into the chip pocket of the screw tap, the handle is rotated to screw out the broken screw tap, threads can still be machined, the broken screw tap is taken out, meanwhile, integrity of the threads are guaranteed, and convenience and effectiveness are achieved.

Description

technical field [0001] The invention relates to a device and method for taking out a broken thread tap, belonging to the technical field of thread processing. Background technique [0002] When processing threads with a tap, it is often encountered that the tap is broken and remains in the workpiece. The method currently used is: use a small punch to slowly punch out the broken wire tap, or break the wire tap into pieces, and use a hook to take out the broken wire tap; large taps can be stacked by electric welding, or the tap can be crushed with flame After burning and annealing, use an electric drill to remove it, or use electric sparks to etch it. The above methods are time-consuming and labor-intensive, and even destroy the integrity of the processed thread. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a broken thread tap extractor and a method for taking it out, which can conv...
