Abstract
The utility model provides a rotating spindle which is suitable for heavy current and has long service life. The rotating spindle comprises a spindle body, a rotating body, three axial constraint wheels, two radial constraint wheels, three carbon brushes and a synchronizing wheel, wherein the axial constraint wheels are arranged between the spindle body and the rotating body, and the synchronizing wheel is fixed on the rotating body. The rotating spindle is characterized in that the spindle body is an octagon body. The carbon brushes are arranged on the octagon spindle body, so that the rotating body does not generate too much heat when the heavy current passes through the rotating body, and the service life of the rotating spindle is prolonged.
Description
Technical field
The utility model relates to welding and cutting equipment field, relates in particular to a kind of rotary main shaft.
Background technology
Common heating installation head welding equipment generally is equipped with two welding guns, and two welding guns are positioned at the same side of rotary main shaft, simultaneously running; Welding heating installation head; Because the head queuing is put, each head all has the deviation of oneself, for example each head deviation+0.50mm; Two head accumulated errors are 1mm, and the deviation of this 1mm is fatal deviation for welding quality.In order to increase work efficiency and welding quality, welding equipment adopts four to be in the layout of the rotary main shaft both sides to welding gun, and workpiece also is placed in the rotary main shaft both sides, and this layout overcomes the head accumulated error, has guaranteed high-quality welding.Weld rotary main shaft both sides workpiece simultaneously.But be to use four welding guns, required electric current is bigger, and the rotary main shaft of welding equipment only uses a carbon brush, and heating easily causes damaging, and life is used in influence.
Summary of the invention
In order to solve the problems of the technologies described above; The utility model provides a kind of rotary main shaft that is applicable to big electric current, long service life; Comprise axis body, rotary body, be arranged on axial constraint wheel, radial constraint wheel and carbon brush between axis body and rotary body, be fixed on the synchronizing wheel on the rotary body; It is characterized in that said axis body is eight limit bodies, the quantity of said carbon brush is three.
The quantity of said carbon brush is three.
The beneficial effect of the utility model is: a plurality of carbon brush are installed on octagonal axis body, can not produce too much heat when making on the rotary body through big electric current, prolonged the service life of rotary main shaft.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in Figure 1,2 of axis body 1 and rotary bodies are equipped with axial constraint wheel 3, radial constraint wheel 4 and carbon brush 5, and axis body 1 is an octagon, and axial constraint is taken turns 3 three groups, 4 liang of groups of radial constraint wheel, and the quantity of carbon brush 5 is three, synchronizing wheel 6 is fixed on the rotary body 2.
