Position-adaptive carbon brush device

Abstract

The invention belongs to the technical field of conductive devices, and particularly relates to a position-adaptive carbon brush device. The position-adaptive carbon brush device comprises a fixed seat, wherein a linear guide device is arranged on the fixed seat; a mounting plate is arranged on the linear guide device; a telescopic device is further fixedly arranged on the fixed seat; a telescopicpart of the telescopic device is fixedly connected with the mounting plate; an insulating plate is arranged on the mounting plate; a U-shaped plate is arranged on one surface, far away from the mounting plate, of the insulating plate; a conductive copper plate is arranged at the groove bottom of the U-shaped plate; carbon brush seats are arranged on two outer side surfaces of the U-shaped plate;the carbon brush seats are of hollow closed-loop structures; carbon brush blocks are clamped in the carbon brush seats; blind grooves are formed in one ends, far away from the telescopic device, of the carbon brush blocks in the sliding direction of the carbon brush blocks; limiting devices extending into the blind grooves of the carbon brush blocks are fixed on the carbon brush seats; elastic elements are arranged at the opening ends, far away from the blind grooves of the carbon brush blocks, of the carbon brush seats; and a limiting rod is arranged on one surface, far away from the telescopic device, of the mounting plate. According to the position-adaptive carbon brush device, the problem of electric conduction of a workpiece at a split part of welding equipment is solved, and the position-adaptive carbon brush device can be adaptive to the conductive position.

Description

technical field [0001] The invention belongs to the technical field of conductive devices, and in particular relates to an adaptive position carbon brush device. Background technique [0002] As a sliding contact, carbon brushes are often used in electrical equipment to transmit energy or signals between the fixed part and the rotating part of the rotating machine. In the field of welding, carbon brushes are often used for the negative electrode of the rotary displacement device to conduct electricity, and can only be used in occasions where the contact surface is not disassembled. For the conduction of movable workpieces, manual ground wires or ground wire clamps are often used, which is inefficient and poses a great safety hazard, which is not conducive to the needs of equipment automation. For this purpose, an adaptive position carbon brush device is designed. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, th...
