Abstract

The invention relates to a tapping device capable of machining internal threads and external threads. The tapping device comprises a tapping machine and a workpiece clamping assembly. After a workpiece is clamped through the workpiece clamping assembly, thread machining is performed through the tapping machine. The tapping machine comprises a platform. A vertical shaft is installed on the platform. One end of a lower supporting arm is rotationally installed on the vertical shaft. The other end of the lower supporting arm is hinged to the lower end of a longitudinal supporting arm. The upper end of the longitudinal supporting arm is hinged to one end of an upper supporting arm through a connector. A vertically-arranged connecting shaft is installed at the other end of the upper supporting arm. A chuck is installed at the lower end of the connecting shaft. The workpiece clamping assembly comprises a support. A supporting frame is installed on one side of the support. A top board is fixedly arranged at the upper end of the supporting frame. A hydraulic cylinder is vertically installed upwards at the portion, corresponding to the top board, of the support. A pair of clamping pieces are symmetrically installed at the piston rod end of the hydraulic cylinder and the lower end face of the top board. The tapping device is simple in structure, scientific and reasonable in design, flexible in operation, convenient to operate, high in tapping accuracy and capable of effectively improving the work efficiency.

Description

technical field [0001] The invention belongs to the technical field of thread processing equipment, and relates to a tapping machine, in particular to a tapping device capable of processing inner and outer threads. Background technique [0002] A tapping machine is a machine tool that uses taps to process threads. Traditional tapping machines can only process internal threads, and external threads are usually processed by lathes. At present, there is a tapping machine capable of processing external threads on the market, but this tapping machine has a complex structure and cumbersome operation, and cannot process external threads of longer workpieces. [0003] After searching, a patent document related to the content of this patent was found, the publication number is CN203343561U, and the name is "A Rotary Arm Type Flexible Shaft Drive Electric Tapping Machine", which includes a working machine table, a tap chuck, a bracket seat and a device. On the motor seat plate on the...
