Installation and removal, practical operation is extremely inconvenient.
A kind of improvement numerical control of utility model patent ZL 201520040735.7(is electrolysed rifling manufacture horizontal machine tool) it is turning round
A bearing is set on axis, bearing outer ring is fixed by bearing block, and inner ring and axis cooperate, though the device is able to achieve revolute function,
But the exact position of axis body needs to realize by adjusting bearing block, and when rotating shaft breaks down, the adjusting of the structure and more
Change poles is inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of large-size horizontal numerical control electrolytic machine tool conduction shaft devices, solve actual production
In there are problems that the easy ablation of conductive shaft, replacement be inconvenient and the disassembly of pull rod difficulty.
In order to reach the purpose of the present invention, the invention proposes following technical solutions: being fixedly mounted on bottom plate, the carbon
It brushes on radial two end faces for being set to substrate, end and conductive shaft axis body are in close contact, and conductive shaft axis body is set up in a pair
On bracket component, it is characterised in that: the electrolyte inlet tube is connected by flange with NC rotary table, conductive shaft axis
Body passes through rotary seal structure respectively and is connected with rod head and NC rotary table；
The central axes of the carbon brush and conductive shaft axis body are radially in angle setting, and carbon brush passes through and fixes in carbon brush sleeve, carbon
Brush holder is diagonally-installed on substrate, and carbon brush sleeve and carbon brush holder are snap fit, replacement easy to disassemble.
Each pair of bracket component includes support, and four bearings, cross bar and a pair of of threaded rod, a pair of of threaded rod are vertically solid
Due on bottom plate, the upper end frame of threaded rod is equipped with cross bar, and the upper end of threaded rod is arranged with positioning bolt, and support is set to threaded rod
Between, holder top and cross bar lower part are respectively arranged with a pair of bearings.
Described rotary seal structure one end is flange, and the other end is the axis with cone boss structure.
Compare with the existing technology, the beneficial effects of the present invention are:
(1) carbon brush can effectively increase the contact area of single carbon brush and conductive shaft using diagonally-installed mode, keep electric conductivity more preferable,
Reduction leads to conductive shaft fever because of poor contact, and even there is a phenomenon where ablations；Carbon brush makes carbon brush using buckle-type mounting means
Replacement be easier realize；
(2) the reliable and stable rotation of entire axis work in-process may be implemented in the connection type of rotary seal structure, provides simultaneously
Good sealing effect is avoided because solution leakage causes junction to be corroded, thus the problem for causing the disassembly of pull rod inconvenient,
Also avoid the problem of electrolyte of leakage is to the corrosion of lathe other component；
(3) design bracket component can preferably realize conductive shaft rotation centering, reduce position error；Pass through adjusting nut
Guarantee the regulative mode of conductive shaft axis body accurate location, structure is simple, convenient and reliable, so that axis body and position of bearings are adjusted and more
Change it is more convenient, simultaneously, it is ensured that repeatedly replacement axis body and bearing after be still able to maintain reliable positioning accuracy.
