Power head of tapping machine

Abstract

The invention belongs to the technical field of machining and discloses a power head of a tapping machine. The power head comprise a power head housing, an assembling head, a feeding power unit and aswarf power unit, wherein the power head housing is fixed to the tapping machine; the assembling head is arranged in the power head housing and is movably connected to the power head housing; the feeding power unit is fixed to the power head housing and can drive the assembling head to stretch outside or shrinks into the power head housing; and the swarf power unit is fixed to the power head housing and can drive the assembling head to rotate. The power head of the tapping machine can machine threads of various specifications needed in the market by arranging the feeding power unit and the swarf power unit which are independent to each other. In addition, the power head of the tapping machine is compact in structure, simple in structure, safe and reliable to use and low in maintenance cost.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a tapping machine power head. Background technique [0002] Tapping is an essential step in the process of manufacturing, installing and assembling mechanical parts. Although people can also use drilling machines to achieve the purpose of tapping in many work sites, there are problems such as cumbersome process, low quality, and accident-prone. [0003] In particular, the existing servo motor tapping power head (patent application publication number CN 103286393A) uses a servo motor to simultaneously control the cutting and feeding actions of the tapping power head. On the one hand, its feed speed and power head rotation speed There is a fixed ratio between them, and only a few specific specifications of threads can be processed, which cannot meet the diverse needs of the market; on the other hand, the internal structure of the servo motor tapping power head is com...

Problems solved by technology

Although people can also use drilling machines to achieve the purpose of tapping in many work sites, there are problems such as cumbersome process, low quality, and accidents.

[0003] In particular, the existing servo motor tapping power head (patent application publication number CN 103286393A) uses a servo motor to simultaneously control the cutting and feeding actions of the tapping power head. On the one hand, its feed speed and power head rotation speed There is a fixed ratio between them, and only a few specific specifications of threads can be processed, which cannot meet the diverse needs of the market; on the other hand, the internal structure of the servo motor tapping power head is complex, and when the motor suddenly idles, it will cause great damage to the gears. , increasing safety risks and maintenance costs
