A kind of new welder that is used for processing starter rotor
Technical field
The present invention relates to the process equipment of the starter that uses on a kind of automobile, especially relate to a kind of new welder that is used for processing starter rotor.
Background technology
The rotor of the starter that uses on the automobile mainly comprises rotating shaft that is connected with motor and core assembly and the commutator that is provided with along rotor coaxial, and the rotor coil on the core assembly is connected on the commutator.Existing starter armature is in order to guarantee being connected of rotor coil and commutator, commutator is provided with a riser station, the circumference of riser station is provided with rotor line holding tank, its main effect one is the end line of location in the rotor coil, the 2nd, and the holding piece that utilizes each holding tank both sides is clamped to each end line of rotor coil on the commutator.It is found that but have in the actual application process, because each end line of rotor coil only is to utilize the holding piece of each holding tank both sides to be clamped on the commutator, therefore, in fact exist many gaps on the contact-making surface of each end line of the rotor coil in holding tank and holding piece, " rosin joint " that just it has often been said, also once the someone wants the contact-making surface of end line and holding piece is welded the contact reliability of the contact-making surface that improves end line and holding piece, but because the area of the contact-making surface of end line and holding piece is bigger, therefore when welding, can produce bigger electric current, and then can produce destruction the commutator of rotor.Also the someone has proposed each end line of rotor coil directly is welded on the imagination of commutator face at present, but but has bigger difficulty in the operation of reality, mainly is to lack the suitable welding equipment of a cover.
Summary of the invention
Technical problem to be solved by this invention provides a kind of new welder that is used for processing starter rotor, can be easily the end line of coil closely be welded on the surface of commutator.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of new welder that is used for processing starter rotor, comprise workbench and the Work fixing device and the welder that are arranged on the described workbench, described Work fixing device comprises that workpiece clamps changement and workpiece advance and retreat cylinder, described workbench and described workpiece clamp first slide mechanism that is provided with between the changement by described workpiece advance and retreat air cylinder driven, described welder comprises anodal mechanism, negative pole mechanism and scolder conveying mechanism, described anodal mechanism is arranged on the top that described workpiece clamps changement, described negative pole mechanism is arranged on the side that described workpiece clamps changement, the oblique setting between described anodal mechanism and described negative pole mechanism of described scolder conveying mechanism.

Described first slide mechanism comprises first guide rail that is fixedly installed on the described workbench and the first slide block group that cooperates with described first guide rail, the described first slide block group is fixedly installed on the below of described workpiece clamping seats, and the cylinder axis of described workpiece advance and retreat cylinder is fixedlyed connected with the described first slide block group.
Described scolder conveying mechanism comprises the scolder fixed station, the scolder seat, weldering frame cylinder, assembly pulley, scolder clamps cylinder, scolder is carried cylinder, the scolder support of scolder delivery head and placement scolder cylinder, described scolder support is fixedly installed on the described workbench, be provided with second slide mechanism between described scolder seat and the described scolder fixed station by described weldering frame air cylinder driven, described assembly pulley, described scolder is carried cylinder, described scolder clamps cylinder and described scolder delivery head is fixedly installed on the described scolder seat, and described scolder delivery head is provided with isolator.
Described second slide mechanism comprises second guide rail that is fixedly installed on described scolder seat below and the second slide block group that cooperates with described second guide rail, the described second slide block group is fixedly installed on the described scolder fixed station, and the cylinder axis of described weldering frame cylinder is fixedlyed connected with described second guide rail.
Compared with prior art, the invention has the advantages that Work fixing device and welder are set on workbench, Work fixing device comprises that workpiece clamps the workpiece advance and retreat cylinder of changement and driving first slide mechanism, and the anodal mechanism of welder is arranged on workpiece clamping changement top, negative pole mechanism is arranged on the side that workpiece clamps changement, the scolder conveying mechanism is oblique to be arranged between anodal mechanism and the negative pole mechanism, as long as the positive pole in the anodal mechanism is contacted with copper cash, negative pole in the negative pole mechanism then can closely be crimped on the surface of commutator, just can produce the scolder thawing that enough heats are carried the scolder conveying mechanism after the turn-on current, thereby the end line of rotor coil directly is weldingly fixed on the periphery of commutator, can increases the reliability that end line contacts with commutator face greatly like this; And the setting of negative pole mechanism can make negative pole closely be crimped on the surface of commutator, can not cause when welding that commutator heating itself produces destruction to commutator thereby can make like this.
