Turning and tapping compound cutter

Abstract

The invention discloses a turning and tapping compound cutter. The turning and tapping compound cutter comprises a cutter shaft, a cutter holder, a drilling hinge part and a tapping thread part, wherein the cutter shaft is connected with the center of the cutter holder, the drilling hinge part is arranged at the front end of the cutter, the tapping thread part is arranged behind the drilling hinge part, the cutter shaft, the cutter holder, the drilling hinge part and the tapping thread part are coaxially arranged, the diameter of the tapping thread part is larger than that of the drilling hinge part, the cutter holder is of a cylindrical convex table structure and comprises a front cutter holder and a rear cutter holder, the front cutter holder and the rear cutter holder are coaxially arranged, the drilling hinge part is a compound cutter or a drill bit, and the compound cutter comprises two alloyed turning cutter blades; and tungsten steel thread tapping is adopted by the tapping thread part, the outer diameter of the tapping thread part is larger than that of the front cutter holder, and the rear cutter holder is further provided with four triangular turning cutter blades. According to the turning and tapping compound cutter, manufacturing procedures such as drilling, reaming and tapping are completed at a time, and complex hole aligning and calibrating are not needed, so that the machining accuracy is improved, the machining procedure is simplified, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a turning and tapping compound tool. Background technique [0002] At present, when assembling and connecting large-scale mechanical equipment, in order to ensure the coaxial accuracy of the threaded holes for connecting parts, it is necessary to prefabricate the holes and then perform drilling, reaming and thread processing. In the above-mentioned processing technology, different processing tools are used, and the operations of tool loading and unloading, centering, and benchmarking are complicated and cumbersome, resulting in slow processing speed and relatively low precision of the processed threaded holes. [0003] For the processing of the inner cavity and inner thread of the faucet spool, the industry currently uses a double-head drilling machine tool to adopt the traditional technology. First, the first spindle head drills the inner hole and then mo...

Problems solved by technology

In the above-mentioned processing technology, different processing tools are used, and the operation is complicated and cumbersome when loading and unloading the tool, centering, and finding the datum, resulting in slow processing speed and relatively low precision of the threaded hole after processing.

[0003] For the processing of the inner cavity and inner thread of the faucet spool, the industry currently uses a double-head drilling machine tool to adopt the traditional technology. First, the first spindle head drills the inner hole and then moves to the other spindle head to tap or thread. , so the processing technology correspondingly leads to the disadvantages of complex structure of the machine tool, high manufacturing cost of the machine tool, large deviation of processing accuracy, slow processing benefit, and unstable product quality.
