Abstract
The utility model discloses a novel spot welder which comprises electrode mechanisms, a cam and a secondary pressurized cylinder. Through the cam principle, three electrodes of the three electrode mechanisms are simultaneously welded with a rotor commutator at the minimum point of the cam. The secondary pressurized cylinder is used for secondary pressurization of the three electrodes. Each electrode mechanism can be tripolar or multipolar. The tripolar or multipolar electrode mechanisms can simultaneously conduct electric welding. Through simultaneously electric welding of the tripolar electrode mechanisms, the blank of high-quality welding of domestic motor commutators is filled, production efficiency is raised, and simultaneously welding quality consistency is guaranteed.
Description
Technical field
The utility model relates to a kind of mash welder, especially the novel point welding machine of three utmost points or multipole while electric welding.
Background technology
At present; Known mash welder is when workpiece and electrode one timing; The resistance of workpiece depends on the resistivity with it. therefore, resistivity is the important performance of materials to be welded. and low its good conductivity of metal (like aluminium alloy) of its poorly conductive of metal (like stainless steel) resistivity that resistivity is high.Therefore, heat production is prone to and heat radiation is difficult during the spot welding stainless steel, and heat production is difficult and heat radiation is prone to during the spot welding aluminium alloy. and during spot welding, the former can use less electric current, and the latter just must be with very big electric current.Resistivity not only depends on and metal species, and is also relevant with condition of heat treatment, processing mode and the temperature of metal.In order to obtain the solder joint of certain intensity, can adopt big electric current and short time, also can adopt little electric current with long-time.Electrode pressure has tangible influence to all-in resistance R between two electrodes, and along with the increase of electrode pressure, R significantly reduces, and the amplitude that welding current increases is little, can not influence the heat production that reduces to cause because of R and reduce.Therefore, Joint Strength always increases along with welding pressure and reduces.But product efficiency is not high in the known first order pole welding machine course of work, can not guarantee consistency of product.
The utility model content
The technical problem that the utility model will solve is that product efficiency is not high in the mash welder course of work, can not guarantee consistency of product.The utility model provides the novel point welding machine of a kind of three utmost points or multipole while spot welding, has filled up the blank of state's inner motor commutator high quality welds, has guaranteed the uniformity of welding quality when having improved production efficiency.
The utility model solves the technical scheme that its technical problem adopted: a kind of novel point welding machine; Comprise electrode mechanism, cam and secondary pressurization cylinder composition; Three electrodes while welded disc turbine rotor commutator when the cam minimum point, secondary adds air cylinder three electrodes is carried out the secondary pressurization.
The beneficial effect of the utility model is, the blank of state's inner motor commutator high quality welds has been filled up in three utmost points or multipole while spot welding, has guaranteed the uniformity of welding quality when having improved production efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the mash welder structural representation of the utility model.
Among the figure, 1. electrode mechanism, 2. cam, 3. secondary adds air cylinder.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1; One embodiment of a kind of novel point welding machine of the utility model is proposed; Comprise that electrode mechanism 1, cam 2 and secondary add air cylinder 3 and form, three utmost point electrode movement modes are that three electrode mechanisms 1 pass through cam 2, and pressurize through the pressure effect of cam 2; Three electrode mechanisms 1 while welded disc turbine rotor commutator when cam 2 minimum points, secondary adds air cylinder 3 three or more electrode is carried out the secondary pressurization.Can to be provided be three utmost points or multipole electrode mechanism to electrode mechanism in practice process; And this three utmost point or multipole electrode mechanism can carry out electric welding simultaneously; To realize the blank of motor commutator high quality welds, guaranteed the uniformity of welding quality when having improved production efficiency.
