Description
Technical field
The utility model is related to a kind of slip ring, especially a kind of miniature single channel high current slip ring.
Background technology
Slip ring is widely used in the system for need relative rotation transmits signal and electric current to use.Slip ring use is in automatic welding
On picking, high current, while the welding wire that intermediate via can be used among by cable are transmitted with cable connection.Because of automatic welding
The use characteristic of machine, cable need to reverse with soldering tip, while needing to carry out the transmission of high current, it is therefore desirable to cable it
Between one slip ring of installation ensure electric current smoothly continual transmission in rotary course.Because soldering tip need considerable flexibility with
And cable needs to transmit prodigious electric current, therefore common high current slip ring cannot be satisfied requirement.This slip ring is replaced using main shaft
Copper ring directly transmits the form of electric current, can be that product design is smaller while ensureing current-carrying capacity, meet requirement.
Currently, in order to solve problems, generally with the following method：1, electricity is transmitted using the rotary joint of plain type
Stream；2, using common hole-through conductive slip ring parallel connection overcurrent.But it has the following deficiencies：1, the rotary joint of plain type is adopted
Conduction is carried out with the contact friction of simple shrapnel, although appearance and size can accomplish smaller, this contact form can not
It leans on, cannot be satisfied the requirement for stablizing transmission electric current.2, common via hole type conducting slip ring shape is bigger than normal, and because internal structure is special
Property current-carrying capacity is unable to reach hundreds of amperes of requirement, can not fully meet the requirement of automatic arc welding.
Utility model content
In order to overcome disadvantage mentioned above, the utility model to be intended to provide a kind of miniature single channel high current slip ring, solve automatic
Bonding machine at work cable need rotation while need transmit electric current the problem of.
To achieve the goals above, the technical solution adopted by the present invention is：A kind of miniature single channel high current slip ring, by turning
Through-hole is arranged in son, stator and drive end bearing bracket, rear end cap composition, the slip ring centre, and the rotor includes main shaft, rotor wiring
Column, the stator include brush carrier, brush line and relay terminal, and the brush carrier places the brush line, the master equipped with hole
The rotor wiring column is arranged in axis front end, and the relay terminal is arranged in the rear end cap, and the main shaft passes through with the brush line
Contact friction is conductive, and the main shaft is connect with the rotor wiring column, and the electric current of the brush line is transferred to by the brush carrier
The relay terminal, the rotor wiring column and the relay terminal external cable.
Further, the brush carrier is abutted by screw rod and the drive end bearing bracket, rear end cap fixation.
Further, the through-hole and the rotor wiring column and the relay terminal are concentric.
Further, the brush carrier uses brass material.
Compared with prior art, the beneficial effects of the utility model are：1, copper ring and brush line is replaced to be in direct contact using main shaft
Conduction increases the contact area of contact, while stable transmission high current, reduces appearance and size；2, both ends use
The form of binding post, the convenient cable butting with automatic welding machine, while having via among slip ring can allow welding wire among cable
It goes through, is suitable for automatic welding machine；3, brush carrier uses brass material, and all brush lines is made directly to all turn on, and eliminates interior
Portion's shorting stub keeps electric current transmission more direct, and less occupancy slip ring inner space makes appearance and size smaller.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the miniature single channel high current slip ring of the utility model；
Fig. 2 is the radial section structure chart of the miniature single channel high current slip ring of the utility model；
Fig. 3 is the axial section structure chart of the miniature single channel high current slip ring of the utility model.
Specific implementation mode
The technical issues of in order to keep the utility model solved, technical solution and advantageous effect are more clearly understood, below
In conjunction with the embodiments, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only
To explain the utility model, it is not used to limit the utility model.
It should be understood that the orientation or positional relationship of the instructions such as term "left", "right" in the description of the present invention,
To be based on the orientation or positional relationship shown in the drawings, it is merely for convenience of description the utility model, rather than requires this practicality new
Type must be with specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.
As shown in Figure 1 to Figure 3, a kind of miniature single channel high current slip ring, by rotor 1, stator 2 and drive end bearing bracket 3, rear end cap
Through-hole 5 is arranged in 4 compositions, slip ring centre, and rotor 1 includes main shaft 11, rotor wiring column 12, and stator 2 includes brush carrier 21, brush line 22
With relay terminal 23, brush carrier 21 places brush line 22 equipped with multiple holes, and rotor wiring column 12, rear end is arranged in 11 front end of main shaft
Relay terminal 23 is arranged in lid 4, and through-hole 5 and rotor wiring column 12 and relay terminal 23 are concentric, meet connecing for automatic arc welding
Line requirement.Main shaft 11 is conductive by contacting friction with brush line 22, and main shaft 11 is connect with rotor wiring column 12, and the electric current of brush line 11 is logical
It crosses brush carrier 21 and is transferred to relay terminal 23,23 external cable of rotor wiring column 12 and relay terminal.Different from traditional electricity
What copper ring and insulating trip were spaced successively inside slip ring is sleeved on main shaft 11, and the present embodiment does not need copper ring and insulating trip, compares
Previous slip ring considerably increases the contact area between rotor 1 and stator 2, together in the case of like products length
Shi Yinwei eliminates the structure of copper ring, can make brush carrier 21 from main shaft 11 closer to therefore reducing the appearance and size of product.
Specifically, brush carrier 21 is abutted by screw rod and drive end bearing bracket 3, the fixation of rear end cap 4.Brush carrier 21 uses brass material
Matter makes all brush lines 22 directly all turn on, does not need internal shorting stub, and electric current is made to transmit more direct, less occupancy slip ring
Inner space makes slip ring appearance and size smaller.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, therefore, only
All any modification, equivalent and improvement etc. made by the utility model the description and the appended drawings content are used, this is should be included in
Within the protection domain of utility model.
