Abstract
The utility model discloses an electric conduction device of a welding motion rotary working platform, comprising electric conduction rotating shafts, each of which is connected with at least one electric brush in an approaching way. As the electric brush does not rotate along with the electric conduction rotating shafts, and the connection between the electric brush and the electric conduction rotating shafts is surface contact, the contact area with the electric conduction rotating shafts can be greatly enlarged, and the more stable and stronger current can be provided.
Description
Technical field
The utility model relates to a kind of electric installation, relates to the widely different commentaries on classics workbench of a kind of welding electric installation especially.
Background technology
Weld widely different commentaries on classics workbench when in running order, need to give the rotating shaft that is in rotation conduction, but owing to rotating shaft is being rotated always, can't directly adopt lead that it is powered, existing method is to conduct electricity to rotating shaft by bearing, then is delivered to rotating disk by it again, still, because the phase countershaft of bearing rotates, it is stable that the electric current of its conduction is difficult to keep, and bearing mostly is steel part greatly, and resistance is bigger, bearing is easy to generate high temperature, influences bearing life; In addition, for tangent line is connected, the contact area between bearing and the rotating shaft is little between bearing and the rotating shaft, and the current density of contact-making surface is big, and bearing wear increases.
The utility model content
The purpose of this utility model provides the widely different commentaries on classics workbench of a kind of welding electric installation, to solve the above-mentioned problems in the prior art.This welds widely different commentaries on classics workbench electric installation and by the both sides in the conduction rotating shaft brush is set, and is conducted electricity to rotating shaft by brush, thereby obtains more stable electric current.
The technical scheme that the utility model provides is as follows:
Weld widely different commentaries on classics workbench electric installation, comprise the conduction rotating shaft, it is characterized in that: the brush of at least one is abutted against in each conduction rotating shaft.Because brush is not followed the conduction rotating shaft and rotated, and its face of being connected to the conduction rotating shaft contact, can increase greatly and conducts electricity the contact area of rotating shaft, and more stable, more powerful electric current is provided.In addition, because the contact-making surface of brush and conduction rotating shaft increases, therefore, the current density of contact-making surface decreases, and for bearing, can prolong to some extent the service life of brush.
Preferably, at least two brush symmetry abuts against on the same plane of conduction rotating shaft, guarantees to conduct electricity rotating shaft stress equalization when rotating at a high speed.In addition, for satisfying the needs of high power welding job, need to strengthen conductive electric current, at this moment, if directly the electric current of the single brush of increase can cause local temperature too high, and directly influences brush service life, as preferred means, the brush that at least two group symmetries can be abutted against in the conduction rotating shaft vertically is arranged on the Different Plane of conduction rotating shaft.
The widely different commentaries on classics workbench of aforementioned welding is led in the device of shop, and this brush comprises a lead-in wire and the brush that is attached thereto, and the inner surface of this brush cooperates with the rotating shaft outer surface, and the inner surface of whole brush all can be abutted against on the rotating shaft outer surface, increases contact area.
In the widely different commentaries on classics workbench of the aforementioned welding electric installation, described brush is a copper brush, promptly adopts graphite and metal to make, and the fusing point of graphite is about 3850 ℃, and resistance to elevated temperatures is good, also has favorable conductive and heat conductivility simultaneously.
In the widely different commentaries on classics workbench of the aforementioned welding electric installation, for increasing the magnitude of current that imports the conduction rotating shaft, reduce the friction between brush and the conduction rotating shaft, prolong brush service life, can also fixedly install one in this outside of conducting electricity rotating shaft and can follow conduction rotating shaft rotation, electric conductivity favorable conductive cover.
In the widely different commentaries on classics workbench of the aforementioned welding electric installation, brush is fixed by brush box.After use after a while, brush can produce to a certain degree wearing and tearing, and the built-in spring of brush box can make it be pressed on all the time in the conduction rotating shaft, guarantees the reliability of contact.
Unless name especially, the implication of employed here all technology and scientific terminology is identical with the affiliated common implication of understanding of technical field those skilled in the art of the utility model.Equally, all publication, patent application, patent and other references all can be introduced the utility model as a reference referred in this.
By foregoing description as can be known, the utility model creativeness provides the widely different commentaries on classics workbench of a kind of welding simple in structure electric installation, this welds widely different commentaries on classics workbench electric installation and by the both sides in the conduction rotating shaft brush is set, electric current conducts electricity to rotating shaft by brush, because brush is not followed the conduction rotating shaft and is rotated, thereby can obtain more stable electric current.
Description of drawings
Fig. 1 is the structural representation of the widely different commentaries on classics workbench of the welding of embodiment electric installation.
Wherein, conduction rotating shaft 1, brush 2, conductive sleeve 11 and brush box 3
The specific embodiment
For further specifying the utility model, the specific embodiment of existing accompanying drawings preferred embodiment:
Embodiment 1
The utility model relates to the widely different commentaries on classics workbench of a kind of welding electric installation, as shown in fig. 1, the conductive sleeve 3 that the fixedly sleeved electric conductivity good metal in the outside of conduction rotating shaft 1 is made, two brushes 2 of being made up of brush and lead-in wire limit its position (not shown) by brush box 3, and symmetry abuts against the outside of conductive sleeve 3.
As different from Example 1, the outside of conductive sleeve 3 vertically is provided with 4 groups of brushes, and every group of brush is made up of two brushes 2, and it limits its position by a brush box 3, and symmetry abuts against the outside of conductive sleeve 3.
The foregoing description is the utility model preferred implementation; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
