Abstract
The invention discloses a process for welding neutral points with leads of windings of driving motors of electric vehicles. The process includes steps of S1, removing insulating paint at the ends of the leads, tidying and bundling the ends of the leads, and wrapping and binding the ends of the leads by copper sheets; S2, regulating a voltage of a welding machine so that the voltage of the welding machine ranges from 20V to 25V; S3, instantly welding each neutral point with a connector of the corresponding three-phase lead for 3-6 seconds by the aid of the welding machine and integrating the neutral points with the leads of the windings by means of fusion welding; S4, checking on the welding quality to determine if the welding quality of the neutral points and the leads is qualified or not. The process has the advantages that the welding quality is improved owing to an instant fusion welding mode, and the neutral points and the leads are good in conductivity, high in dynamic overload capacity and efficiency, low in cost and attractive in appearance and are firm, reliable, high-temperature-resistant, vibration-resistant and environmental friendly; the welding quality is improved, so that the quality of the motors is enhanced; the production efficiency is high, and the process is applicable to batch production on assembly lines; production is safe and environmental friendly.
Description
Technical field
The present invention relates to the connection processing technique field of motor winding neutral point and lead-out wire, particularly driving motor of electric vehicle winding neutral point and lead-out wire welding procedure.
Background technology
Drive motors has winding stator core neutral point and three-phase lead-out wire generally to adopt the brazing of flame silver acetylide to connect technique or cold-extrusion technology, the brazing of flame silver acetylide connects technique and has the following disadvantages: 1, cost is high, required silver-copper brazing alloy during welding, price is 3500 yuan/kg approximately, every consumption of big bus motor is 0.1～0.15kg approximately, auxiliary materials that disappear such as aerobic gas, acetylene, scaling powder also in welding process, silver-bearing copper welding material cost is higher; 2, take a lot of work, the brazing of flame silver acetylide connects and is not suitable with pipelining, and production efficiency is low, dangerous, not environmental protection; 3, of poor quality; 4, profile is not attractive in appearance.
The cold-extrusion technology that drive motors has winding stator core neutral point and three-phase lead-out wire to adopt has the following disadvantages: the winding quality of connection is poor, and it is unreliable that winding leading-out wire connects, and has the virtual connections phenomenon, and contact resistance is large, temperature rise; The three-phase dc resistance unbalance easily occurs, thereby affect motor performance.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide that a kind of production efficiency is high, cost is low, driving motor of electric vehicle winding neutral point and the lead-out wire welding procedure of environmental protection, reliable welding quality.
Purpose of the present invention is achieved through the following technical solutions: driving motor of electric vehicle winding neutral point and lead-out wire welding procedure, and it comprises the following steps:
The insulated paint of S1, removal lead-out wire end, the arrangement of lead-out wire end is bundled, tighten the lead-out wire end with the copper sheet parcel;
The voltage of S2, adjusting bonding machine is 20～25V, mainly according to weldment diameter setting voltage value;
S3, employing bonding machine moment welding winding neutral point and three-phase pinout connector, be 3～6 seconds weld interval, winding neutral point and lead-out wire melting welding are welded as a whole;
S4, inspection welding quality, qualified getting final product.
The present invention has the following advantages: the present invention adopts moment melting welding welding to replace silver-bearing copper welding and cold extrusion to realize the connection of driving motor of electric vehicle winding neutral point and lead-out wire, improved welding quality, not only conduct electricity very well, solid and reliable, the dynamic overload ability is strong, high temperature resistant, shock-resistant, vibration resistance, and efficiency is high, cost is low, environmental protection, appearance looks elegant.
The present invention is in the situation that, without scolder, the use bonding machine directly carries out melting welding to winding neutral point and lead-out wire, has promoted welding quality, thereby has promoted the motor quality; Production efficiency is high, is useful on streamline and produces in batches; Production safety, environmental protection.
The specific embodiment
Below the present invention will be further described, protection scope of the present invention is not limited to the following stated:
Driving motor of electric vehicle winding neutral point and lead-out wire welding procedure, it comprises the following steps:
The insulated paint of S1, removal lead-out wire end, clean lead-out wire end and driving motor of electric vehicle winding neutral point surface, wipe oil or corrosion etc., the arrangement of lead-out wire end is bundled, tighten the lead-out wire end with the copper sheet parcel;
The voltage of S2, adjusting bonding machine is 20～25V, mainly according to weldment diameter setting voltage value;
S3, employing bonding machine moment welding winding neutral point and three-phase pinout connector, be 3～6 seconds weld interval, winding neutral point and lead-out wire melting welding are welded as a whole, the bonding machine adopted can be instantaneous welder, pass through to produce high heat by immediate current, thereby bonding machine moment welding winding neutral point and three-phase pinout connector are welded together;
S4, inspection welding quality, qualified getting final product.
Driving motor of electric vehicle winding neutral point and lead-out wire adopt moment melting welding welding to replace silver-bearing copper welding and cold extrusion, improved welding quality, not only conduct electricity very well, solid and reliable, the dynamic overload ability is strong, high temperature resistant, shock-resistant, vibration resistance, and efficiency is high, cost is low, environmental protection, appearance looks elegant.
