Abstract
The utility model relates to a rotating grounding device. The rotating grounding device includes a core shaft, a rotating body, and a pressure bearing, wherein the rotating body is mounted in a shaft part of the core shaft; the pressure bearing is mounted at the shaft part of the core shaft and located at an external part of the rotating body, and the contact surface of the rotating body and the core shaft, and the contact surface of the rotating body and the pressure bearing are respectively provided with an insulting sleeve; the insulting sleeve is in a cylinder shape with an edge, a cylinder wall of the insulating sleeve is located at the contact surface of the rotating body and the core shaft, and the edge of the insulating sleeve is located at the contact surface of the rotating body and the pressure bearing; and the insulating sleeve is made of insulating bakelite material. With the rotating grounding device, adhesion phenomenon of the rotating body and the core shaft is avoided, and all current is guaranteed to be conducted by a work surface. The insulating sleeve is an integrated part, thus can be replaced and maintained easily.
Description
Technical field
The utility model is a kind of conventional device, specifically a kind of rotary grounding device in welding job.
Background technology
Rotation ground connection is mainly used in automatic welding industry, electric current conduction during welding rotational workpieces, and its main feature is that voltage is low, electric current is large.This rotation ground connection is to conduct electricity by the plane contact of mandrel working face and rotary body, the weak spot of rotation ground connection is the fit clearance between rotary body and mandrel, gap too hour, rotary body rotates difficulty, and equipment is caused to damage, gap slightly bigger childhood, between rotary body and mandrel have large electric current by time will produce sparkover, make the contact-making surface generation pit between the two affect rotating effect, when serious, rotary body and mandrel can be sticked together, cause whole rotary grounding device to be scrapped.If inject conductive paste between rotary body and mandrel, can play effect lubricated and conduction, can reduce electric discharge phenomena to a certain extent.But when environment is poor, dust enters whole device, mix into scoriform thing with conductive paste, or all can cause not in time whole device rotation to have some setbacks owing to adding conductive paste.
Summary of the invention
In order to solve the problems of the prior art, guarantee that all electric currents are all conducted by working face, the utility model provides a kind of rotary grounding device, comprises mandrel, rotary body, pressure bearing, and rotary body is arranged on mandrel axial region; Pressure bearing is arranged on the outside of mandrel axial region in rotary body, and the contact-making surface at contact-making surface, rotary body and the pressure bearing of rotary body and mandrel is provided with insulating case: described insulating case is the tubular with edge, the contact-making surface of its barrel in rotary body and mandrel, it is the contact-making surface in rotary body and pressure bearing along portion; Described insulating case is that bakelite is material.
The utility model has been avoided the adhesion phenomenon of rotary body and mandrel, guarantees that all electric currents are all conducted by working face, and the as a whole parts of insulating case are changed maintenance very convenient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: mandrel 1, rotary body 2, insulating case 3, pressure bearing 4.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
The utility model is for a kind of rotary grounding device that can guarantee that all electric currents are all conducted by working face is provided, and comprises mandrel 1, rotary body 2, pressure bearing 4, and rotary body 2 is arranged on mandrel axial region; Pressure bearing 4 is arranged on the outside of mandrel 1 axial region in rotary body 2, and is provided with a whole insulating element at the contact-making surface of the contact-making surface of rotary body 2 and mandrel 1, rotary body 2 and pressure bearing 4, and it can be an insulating case 3.Described insulating case 3 is the tubular with edge, its barrel between rotary body and the contact-making surface of mandrel, its along portion between rotary body 2 and the contact-making surface of pressure bearing 4.Increased after this insulating case 3, the conductive site between rotary body 2 and mandrel 1 is completely fixed on working face, and whole device rotates flexible, smooth and easy.The link of having removed filling conductive paste from, can not affect because of human factor the life-span of whole device, and the adaptive capacity of environment is also strengthened greatly.
Described insulating case is that bakelite is material.Because adopt, this cost of material is low, heat-resisting quantity and good insulation preformance.
The utility model has been avoided the adhesion phenomenon of rotary body and mandrel, guarantees that all electric currents are all conducted by working face, and the as a whole parts of insulating case are changed maintenance very convenient.
