Handheld Electric Threading Machine and Threading Method

Abstract

The invention relates to a tool for processing threads for pipe fittings, in particular to a hand-held electric wire threading machine and a thread threading method. The present invention includes a power driver, and its structural features are: it also includes a gearbox mechanism, a transfer sleeve mechanism and a support arm mechanism, the gearbox mechanism is installed on the power driver, the transfer sleeve mechanism is installed on the gearbox mechanism, and the support arm body The mechanism cooperates with the adapter sleeve mechanism, and the transmission mechanism includes the transmission assembly, the small bevel gear assembly, the large bevel gear assembly, the triple gear shaft assembly, the feed gear shaft assembly, the output gear assembly, and the transition gear assembly. The small bevel gear assembly meshes with the large bevel gear assembly, the large bevel gear assembly meshes with the triple gear shaft assembly, the reversing assembly cooperates with the output gear assembly, and the output gear The assembly meshes with the triple gear shaft assembly or the feed gear shaft assembly respectively, the output gear assembly meshes with the transition gear assembly, and the transition gear assembly meshes with the large toothed disc.

Description

technical field [0001] The invention relates to a tool for processing threads for pipe fittings, in particular to a hand-held electric threading machine and a threading method. Background technique [0002] The common hand-held electric threader on the market is mostly copper worm gear drive structure. This kind of handheld electric threader has the characteristics of low and unstable transmission, difficult to ensure cooling and heat balance, high noise and low durability of parts. At the same time, this type of threading machine controls the direction of the motor to achieve the effect of advancing and retracting the knife, so the speed of the advancing and retracting knife is generally the same, the requirements of the motor are relatively high, and the damage to the worm gear is also large, but the work efficiency is low. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and to provi...

Problems solved by technology

[0002] The common hand-held electric threading machines on the market are mostly copper worm gear transmission structures. This type of hand-held electric threading machines has the characteristics of low transmission efficiency and instability, difficult to ensure cooling and heat balance, high noise and low durability of parts.

At the same time, this type of threading machine controls the motor to change direction to achieve the effect of advancing and retreating the knife, so the speed of advancing and retreating the knife is generally the same. The requirements for the motor are relatively high and the damage to the worm gear is also large, but the work efficiency is low.
