Common boring cutter structure generally comprises handle of a knife and the cutter in handle of a knife front end is arranged, and handle of a knife rear end is mounted on lathe
On, power, which is provided, by lathe when use carries out boring processing.But existing boring cutter, boring processing performance is limited, big for depth
In the deep hole boring processing of 6 times of diameter or more, it is also difficult to ensure precision and processing efficiency.
Invention content
In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is to：How to provide one kind can be real
Existing electronic feed, improves processing stability, and the boring range of work is big, and applicability is wide, the uniaxial electricity of deep hole boring of high precision machining
Dynamic mechanical arm.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions：
A kind of deep hole boring single shaft motor machine arm, including whole cylindrical handle of a knife and cutter, Cutting tool installation manner is in knife
In the segment of cutting of handle front end, which is characterized in that be additionally provided with electric feeder on the handle of a knife, and for realizing being added
The cutter stable supporting device of work hole inner support.
In this way, the present apparatus is in use, the installation of handle of a knife rear end is fixed on lathe, processed object is installed on lathe simultaneously
It drives rotation to provide principal cutting movement by lathe, realizes cutter radial feeding adjusting by the electronic feed of electric feeder, lean on machine
Bed drives handle of a knife to realize axial feed, and then can realize electronic feed, realizes various inner hole structure borings.The knife of setting simultaneously
Tool stable supporting device can improve processing stability, realize deep hole boring processing, improve machining accuracy.
As an optimization, the segment of cutting includes a Cutting tool installation manner groove for being located at the setting of handle of a knife forward position, Cutting tool installation manner
Slot includes being used to form the tool bit part of cutting edge and being passed for realizing installation and cutter radial feeding for installing cutter, cutter
The cutting-edge of dynamic installation handle portion, tool bit part exposes outside Cutting tool installation manner groove, and tool bit part and installation handle portion are seperated
Formula is designed and is fixed by bolts and is connected as one, and is installed and is provided with driving rack on the medial surface of handle portion for realizing cutter
Radial feed is driven.
In this way, cutter is realized using cutter head and installing handle two-part structure, cutting edge is formed by tool bit part, in this way, can
With for cut and install different requirements respectively use different materials, with improve cutting edge process intensity while reduce at
This.Cutter is divided into two parts simultaneously, setting drive mechanism in installation handle portion is facilitated to realize cutter radial feeding transmission.It should
Drive mechanism uses driving rack, conveniently can engage with transmission input gear and realize tool feeding feeding transmission, simple in structure
And it is accurately controlled conducive to transmission ratio.
As an optimization, the Cutting tool installation manner groove and corresponding cutter have two sets and are arranged around handle of a knife axial line reverse symmetry.
