Carbon brush spring welding machine

Abstract

The invention discloses a carbon brush spring welding machine which is provided with a rack, a workbench is arranged in the center of the top of the rack and comprises a rotary table, a pneumoelectric slip ring is arranged in the center of the rotary table and electrically connected with a servo motor arranged in the rack, and the servo motor is electrically connected with the rotary table. The servo motor is in transmission connection with the turntable through a cam divider arranged in the rack; a plurality of sets of carriers are arranged on the top of the rotary table in a circular array mode with the pneumoelectric slip ring as the center, a carbon brush feeding device, a wire drawing device, a spring feeding mechanical arm and a contact piece feeding device are annularly arranged on the portion, located on the outer side of the workbench, of the rack in the anticlockwise direction with the workbench as the center, and a welding device is arranged between the contact piece feeding device and the workbench. According to the carbon brush spring welding machine, automatic feeding machine welding work of the carbon brush, the spring and the contact piece can be achieved, manpower is saved, the production cost is saved, the working efficiency is effectively improved, stability is good, the product quality is guaranteed, and industrial popularization is facilitated.

Description

technical field [0001] The invention relates to a carbon brush spring welding device, in particular to a carbon brush spring welding machine. Background technique [0002] Carbon brush, also called electric brush, is a kind of sliding contact, which is widely used in many electrical equipment, such as various motors, generators, and axle machines. [0003] The carbon brush is mainly made of electrochemical graphite or grease-impregnated graphite or metal (copper, silver) graphite. On the motor shaft, the end of the wire is welded with a metal contact piece, which is convenient for conducting electricity. When the motor rotates, the electric energy is transmitted to the coil through the commutator. [0004] Due to the particularity of the structure, the carbon brushes provided with springs and contact pieces are mainly processed manually at present. The operator first connects the spring to the outside of the wire on the carbon brush, then attaches the head of the wire to t...
