Description
Technical field
The present invention relates to a kind of welding method of three-phase winding connection lines of wheel hub motor of electric bicycle, belong to solder technology.
Background technology
The welding method of three-phase winding connection lines of wheel hub motor of electric bicycle of the present invention comprises the welding method of three-phase winding connection lines common contact, and the welding method of three-phase winding connection lines and power outlet.
The stator of the described wheel hub motor of prior art is to the welding method of joint between the common contact between the winding and winding lead-out wire and the power outlet, and general what adopt is that molten soldering connects method.Described soldering causes phenomenons such as rosin joint, dry joint and not prison welding extremely easily, and plumb joint even is burnt out owing to contact resistance is easy to heating greatly; And in its welding process, the soldering silk volatilizes a kind of pernicious gas, contaminated environment.And the employing spot welding method exists spot welding not firm again, and problem such as come off easily; If adopt the argon arc welding method, then there is the equipment price costliness, the welding temperature height damages winding and lead-in wire easily, directly influences the quality of finished product.
Summary of the invention
The present invention aims to provide a kind of technology advanced person, the solder joint firm and reliable connection, and the solder joint contact resistance is very little, and is easy and simple to handle, the production efficiency height, the welding method of the three-phase winding connection lines of wheel hub motor of electric bicycle that site environment is good is to overcome the deficiency of prior art.
The present invention realizes that the technical though of its purpose is, adopts electric resistance welding to substitute existing welding methods such as soldering; Provide a kind of on the electric resistance welding equipment that is adopted simultaneously, implement the concrete processing step of electric resistance welding, problem such as lean on to overcome rosin joint, dry joint and not prison welding, thereby effectively guarantee welding quality; Improve the production work efficiency,, and save production cost, realize clean production without auxiliary materials such as scolding tin.
Based on above-mentioned technical though, the present invention realizes that first technical scheme of its purpose is:
A kind of welding method of three-phase winding connection lines of wheel hub motor of electric bicycle common contact adopts the resistance welder with metal clip electrode and graphite electrode, it is characterized in that, takes resistance welding method, and may further comprise the steps successively:
A, the operating voltage of regulating resistance welder according to winding wire line footpath thickness; Described operating voltage is controlled in 20～100V scope;
B, the lead riser of three phase windings twisted together form welding the end of a thread;
C, state the welding the end of a thread that twists together, and expose outside one section welding the end of a thread at metal clip with metal clip electrode holder residence;
D, with the described welding the end of a thread moment starting arc that exposes of the quick percussion of graphite electrode; The described sealing wire first meltization that exposes forms public plumb joint.
By above given technical scheme, can understand that in conjunction with technical though of the present invention the present invention is owing to creatively adopt the method for electric resistance welding, and implement advanced processing step, thereby realize its purpose that will realize.
The present invention advocates that also the length of the formed welding the end of a thread of b step is controlled in 10～15mm scope; The described length that exposes welding the end of a thread of c step is controlled in 5～8mm scope.But be not limited to this.Because the width size of metal clip motor directly affects the three-phase winding connection lines head and twists together the length that forms welding the end of a thread.In order to save cost, guarantee welding quality, the present invention advocates the described length that twists together the welding the end of a thread that forms, should be just right, unsuitable long.
Based on above-mentioned same technical though, the present invention realizes that second technical scheme of its purpose is:
The welding method of a kind of three-phase winding connection lines of wheel hub motor of electric bicycle and power outlet adopts the resistance welder with metal clip electrode and graphite electrode, it is characterized in that: take resistance welding method, and may further comprise the steps successively.
A, according to power outlet and winding leads line footpath thickness, the operating voltage of regulating resistance welder; Described operating voltage is controlled in 20～100V scope;
B, power outlet and winding leads twisted together form welding the end of a thread;
C, state the welding the end of a thread that twists together with metal clip electrode holder residence; And expose outside one section welding the end of a thread at metal clip;
D, with the described welding the end of a thread moment starting arc that exposes of the quick percussion of graphite electrode; The described sealing wire first melt formation plumb joint that exposes.
The present invention advocates that also the length of the formed welding the end of a thread of b step is controlled in 10～15mm scope; The described length that exposes welding the end of a thread of c step is controlled in 5～8mm scope.
After technique scheme was implemented, the method that the present invention had was reliable, and technology is easy, and it is firm to weld, conduct electricity very well, and production work efficiency height, production cost is low, and compared with the prior art characteristics such as on-the-spot environmental protection, have outstanding substantive distinguishing features and marked improvement.
Description of drawings
