Description

Automatic tapping device for precision castings Technical Field The invention relates to the technical field of tapping, in particular to an automatic tapping device for precision castings. Background Tapping is a machining process for cutting internal threads on a prefabricated bottom hole through a tap, and is a core method for manufacturing the internal threads in machining. The existing tapping machine is used for tapping by driving the screw tap to rotate, a large amount of scrap iron can be generated in the processing process, and the scrap iron can be sputtered to the periphery of the tapping machine and is difficult to collect. And if the scraps cannot be cleaned in time, the working efficiency of the tapping machine can be influenced. In particular, for the production of precision castings, the requirements are strict, and if the tapping is disturbed by scraps, errors occur in the tapping, the time for reworking is required, so that the production efficiency is seriously affected. Some solutions to the above problems are also presented in the prior art.
