Portable screw tap anti-breaking electric tapping machine

Abstract

The invention belongs to the field of hardware tools, and particularly relates to a portable screw tap anti-breaking electric tapping machine which comprises a shell, a grip is arranged at one end of the shell, a battery is arranged in the side, close to the grip, of the shell, a tapping mechanism is arranged in the shell, a lubricating mechanism is arranged in the tapping mechanism, and the tapping mechanism comprises a rotating block rotationally arranged in the shell; a connecting cavity with an opening deviating from the battery is formed in the rotating block, a section breaking block is rotationally arranged in the connecting cavity, an anti-breaking mechanism for controlling connection of the tapping mechanism and the lubricating mechanism is arranged in the rotating block, and meanwhile, the anti-breaking mechanism further controls spraying of lubricating liquid in the lubricating mechanism; and a sealing cover can enable a small amount of air to enter a lubricating oil tank cavity, and a piston plate is slowly pressed to slide, so that a small amount of lubricating oil in the piston plate is sprayed onto the screw tap through a pressure oil nozzle along a lubricating pipe, lubrication is carried out when the screw tap is used for tapping, and the friction force between the screw tap and a preformed hole is reduced.

Description

technical field [0001] The invention belongs to the field of hardware tools, in particular to a portable anti-break electric tapping machine for taps. Background technique [0002] The electric tapping machine is a kind of internal thread tapping machine tool for the forward and reverse fastening connection threads, transmission connection threads and pipe threads of various small and large steel parts with coarse teeth, fine teeth, and non-standard pitches. , but during assembly, because the threaded holes of some workpieces are inclined or too small, the assembly workers usually use electric drills to install taps for tapping. There are no small tapping machines for assembly workers to use, and there are The following questions: [0003] ①Due to the different hardness of the workpiece, it is easy to break the tap when tapping a harder workpiece; [0004] ②When tapping, the tap will be withdrawn and dipped in lubricating oil before continuing to tap only when it cannot be...

[0002] The electric tapping machine is a kind of internal thread tapping machine tool for the forward and reverse fastening connection threads, transmission connection threads and pipe threads of various small and large steel parts with coarse teeth, fine teeth, and non-standard pitches. , but during assembly, because the threaded holes of some workpieces are inclined or too small, the assembly workers usually use electric drills to install taps for tapping. There are no small tapping machines for assembly workers to use, and there are The following questions:

[0003] ①Due to the different hardness of the workpiece, it is easy to break the tap when tapping a harder workpiece;

[0004] ②When tapping, the tap will be withdrawn and dipped in lubricating oil before continuing to tap only when it cannot be tapped, and the tap is easily broken in the workpiece when it cannot be tapped;

[0005] ③Most of the existing electric tapping machines are large desktop tapping machines, which are inconvenient to carry
