According to the automatic tapping device, the action of the driving device and the action of the tensioning device are controlled through the controller in a whole process; the automation degree is high; the working efficiency is greatly improved; the tapping precision is high; the rejection rate is low; production cost is greatly lowered; and the economic benefit is good.

The invention provides a large-stroke and high-speed electric tapper. A clutch transmission case is arranged between a feed machine head of a machine head base and an electric motor. A clutch rotating shaft and a transmission shaft are vertically arranged in the case side by side. The clutch rotating shaft is connected with the electric motor through belt wheel transmission. Two electromagnetic clutches are arranged at the upper end and the lower end of the clutch rotating shaft correspondingly. A first transfer belt wheel and a reversing driving gear which are in sliding fit with the clutch rotating shaft are connected with armatures of the two electromagnetic clutches correspondingly. A second transfer belt wheel and a reversing driven gear engaged with the reversing driving gear are fixed to the transmission shaft. An inner spline sleeve is supported in the head end of the machine head base. Two driven belt wheels on the inner spline sleeve are connected with the first transfer belt wheel and the second transfer belt wheel through conveyor belts correspondingly. The upper section of a main shaft of the feed machine head is a spline section and matched with a spline of the inner spline sleeve. The lower section of the main shaft of the feed machine head is a cylindrical section which is positioned together with a stroke sleeve through a shaft, and the lower section is in sliding fit with the stroke sleeve. A rack is arranged on the outer wall of the stroke sleeve and engaged with a gear shaft. A switch thumbing fork installed on the gear shaft corresponds to a stroke switch.

The invention provides a simple tapping mechanism for a drilling machine. The simple tapping mechanism comprises a friction wheel with a sealing ring, a double-disc type friction wheel, a bearing, supports, a drill bit clamp, a workpiece clamp and a guide rail. The simple tapping mechanism is characterized in that the friction wheel with the sealing ring is connected with a drilling machine main shaft, the double-disc type friction wheel is arranged between the two supports through the bearing, one end of the double-disc type friction wheel is fixedly connected with the drill bit clamp, the workpiece clamp is arranged on the guide rail in a sliding mode, the two supports are fixedly connected to the guide rail through bolts and nuts, and a left wheel body and a right wheel body of the double-disc friction wheel are driven by left-right sliding of the double-disc type friction wheel between the two supports to make contact with the friction wheel with the sealing ring respectively so as to achieve forward and reverse rotating of the drill bit clamp; the drill bit clamp is used for clamping screw taps. By means of the simple tapping mechanism for the drilling machine, the tapping process is made to be easier and more convenient to operate, the reversing process is the tapping process and conducted along with the tapping strength, no active reversing mechanism is needed, the tapping accuracy is improved due to guidance of the guide rail, and meanwhile, the simple tapping mechanism is simple in structure, convenient to maintain and low in cost.

The invention discloses a flexible tapping fixture. The flexible tapping fixture comprises a fixed handle, a sleeve, a cardan joint and a screw tap clamping handle, wherein the lower end of the fixed handle is connected with the upper end of the sleeve, the cardan joint is installed inside the sleeve, the upper end of the cardan joint is connected with the top wall of the sleeve, and the lower end of the cardan joint exceeds the open end of the sleeve and is connected with the screw tap clamping handle. Due to the fact that the sleeve and the cardan joint are installed between the fixed handle and the screw tap clamping handle, and the cardan joint is installed inside the sleeve, during the operation of tapping, under the condition of the center of the screw tap is deviated, the screw tap manufacturing is defect or the feed of a machine tool is insufficient, the precision between the fixed handle and the screw tap clamping handle can be adjusted by the cardan joint, the precision of the tapping can be improved and the service life of the screw tap can be prolonged.
