New welder for processing starter rotor

Abstract

The invention discloses a new welder for processing starter rotor, comprising a worktable and a workpiece fixing device and a welding device arranged on the worktable; the workpiece fixing device comprises a workpiece clamping reversing mechanism and a workpiece advance and retreat cylinder; a first slide mechanism driven by the workpiece advance and retreat cylinder is provided between the worktable and the workpiece clamping reversing mechanism; the welding device comprises a positive mechanism, a negative mechanism and a solder conveying mechanism; the positive mechanism is provided at theupper part of the workpiece clamping reversing mechanism; the negative mechanism is provided at the side of the workpiece clamping reversing mechanism; the older conveying mechanism is slanchwise provided between the positive mechanism and the negative mechanism; the invention has the advantages that contacting the positive pole in the positive mechanism with the copper wire, the negative pole inthe negative mechanism can be closely pressed on the surface of the reverser, after connecting the current, the end line of the rotor coil is directly welded and fixed on the periphery of the reverser, thereby greatly increasing the reliability of contacting the end line with the surface of the reverser.

Description

technical field [0001] The invention relates to a processing equipment for a starter used in automobiles, in particular to a new type of welding machine for processing a starter rotor. Background technique [0002] The rotor of the starter used in the automobile mainly includes a rotating shaft connected to the motor, an iron core assembly and a commutator arranged coaxially along the rotor, and the rotor coil on the iron core assembly is connected to the commutator. In order to ensure the connection between the rotor coil and the commutator in the existing starter rotor, a raised platform is provided on the commutator, and a rotor wire clamping groove is provided on the circumference of the raised platform. Its main function is to position the rotor For the end wires in the coil, the second is to clamp and fix each end wire of the rotor coil on the commutator by using the clamping pieces on both sides of each clamping groove. However, in the actual application process, peo...

AI Technical Summary

Problems solved by technology

However, in the actual application process, people found that since each end wire of the rotor coil is only clamped and fixed on the commutator by the clamping pieces on both sides of each clamping slot, in fact, in the clamping slot There are many gaps on the contact surface between each end wire of the rotor coil and the clamping piece, which is often called "virtual welding". Some people once wanted to weld the contact surface between the end wire and the clamping piece to improve the connection between the end wire and the clamping piece. The contact reliability of the contact surface of the holding piece is high, but due to the large area of ​​the contact surface between the end wire and the holding piece, a large current will be generated during welding, which will damage the commutator of the rotor

At present, some people have proposed the idea of ​​directly welding each end wire of the rotor coil to the surface of the commutator, but there are great difficulties in actual operation, mainly due to the lack of a suitable welding equipment
