Full-automatic floating tapping machine for pipe joint tapping and tapping method thereof

Abstract

The invention discloses a full-automatic floating tapping machine for pipe joint tapping and a tapping method of the full-automatic floating tapping machine. The tapping machine comprises a bottom frame, a panel, a rack, a floating clamping mould in siding connection with the panel, a tapping power machine, a vibrating feeding device, an automatic feeding device, an air cylinder and a PLC controller. The PLC controller is in electrical control connection with the tapping power machine, the automatic feeding device, the floating clamping mould and the air cylinder. A discharge opening is formed in the panel, the piston of the air cylinder is connected with the floating clamping mould, the floating clamping mould comprises a base with a discharge through hole and a hollow chuck, and the base is connected with the hollow chuck through a pressure spring arranged between the base and the hollow chuck. Limit rods are further arranged between the base and the hollow chuck. Supporting rods are further arranged at the bottom of the hollow chuck. The base and the hollow chuck are in elastic floating connection, and therefore when a circle center is automatically found faster and more flexibly, and machining efficiency and machining quality are greatly improved.

Description

technical field [0001] The invention relates to a fully automatic tapping machine and a tapping method thereof, in particular to a fully automatic floating tapping machine and a tapping method used for comb-jack tapping. Background technique [0002] Before combing out of the factory, it needs to tap the inner teeth. Considering material saving and environmental protection, combs are generally thin-walled parts. When tapping them with a tapping machine, it is necessary to align the center of the tap for tapping with the center of the workpiece before tapping. , so as to ensure the quality of the processed workpiece. However, due to the influence of working environment factors such as vibration, tapping head and fixture tolerance, etc., the center of the tap is often not aligned with the center of the workpiece, so that the processed workpiece has serious eccentric quality problems; if it is adjusted manually, it will take time and effort. , and the processing effici...

Problems solved by technology

[0004] The automatic floating tapping device in the above comparison document uses the floating clamping mold to check the center of the three-way workpiece and the tapping tool. The contact between the mold base and the machine base is surface-to-surface contact. When the center is automatically found, The mold seat needs to move on the machine base so that the center of the three-way workpiece is adjusted to the position consistent with the center of the tapping knife, but because the contact between the mold seat and the machine base is surface-to-surface contact, the mold seat is in the The frictional force encountered when moving on the machine base is very large, which will affect its automatic centering, thereby reducing its processing efficiency and processing quality
