Description
Technical field
The utility model belongs to the used pressure head of low voltage electrical apparatus industry contact welding equipment, is meant a kind of high frequency induction welding compressing head especially.
Background technology
In the low voltage electrical apparatus industry, the quality requirement of the important spare part contact in the electrical equipment is improved day by day.At present, big multiple contact welding plant man is all introducing the high frequency induction welding connection technology, the contact of the big specification of welding.The contact of big specification requires welding quality preferably, and higher conductance and lower heating are so most producer all uses the Ag-Cu-Zn solder of high silver content and scaling powder QJ102 to weld.Because welded part is in the magnetic field, and after the energising, contact elements to be welded generates heat, and the scaling powder boiling produces bubble, silver contact under the effect of electromagnetic force, is shifted or spring, so needs pressure head to be fixed in copper touching on the bridge easily during welding.Most of manufacturers all use nonmetallic materials such as pottery, quartz, and these material costs are high, easy to wear, it is broken to be prone to, working face is more coarse under the high temperature, and the silver contact of ablating easily, and being directly fixed on the cylinder can only unidirectional motion, uses limitation higher.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming and defect that prior art exists, and provides a kind of flexibility high high frequency induction welding compressing head.
For realizing above-mentioned purpose, the technical scheme of the utility model is to include fixed handle, sleeve and pressure head, and described fixed handle is fixedly installed in the upper end of sleeve; It is characterized in that: also include guide rod, guide rod back-moving spring and ball rod; Be provided with guide rod straight skidding chamber in the described sleeve, said guide rod guiding is arranged in this guide rod straight skidding chamber slippingly, and the lower surface of described guide rod is provided with the ball pivot groove that is sphere; The head end of described ball rod is a spheroid; The spheroid of this ball rod is rotatable spacing in sleeve, and the spheroid of this ball rod cooperates with the ball pivot groove formation ball pivot of guide rod, and described pressure head is fixedly installed on the lower end of ball rod.Through this setting, rotate in sleeve through ball rod, realized that pressure head can suitably freely adjust angle with contact shape, therefore fixed contact the utlity model has the high advantage of flexibility.
Further being provided with is that described guide rod back-moving spring is a coil tension spring, and it is movably set in guide rod is the outside, and the two ends of this guide rod back-moving spring act on the roof and guide rod in guide rod straight skidding chamber the homing action of formation guide rod respectively.Through this setting, when ball rod rotates, the compression spring, and after ball rod rotate in place, the reset force of spring was fixed the angle of ball rod.
Further being provided with is that described pressure head is the water-cooled pressure head, and this water-cooled pressure head includes and is positioned at its inner flowing water chamber, and the water inlet and the delivery port that are arranged on water-cooled pressure head sidewall.Through this setting, but the pressure head water-cooled is avoided high temperature damage inactivation or distortion.
Below in conjunction with the Figure of description and the specific embodiment the utility model is done further introduction.
Description of drawings
Fig. 1 is a high-frequency induction welder pressure head structure sketch map;
Fig. 2 is a high-frequency induction welder general assembly work sketch map.
The specific embodiment
The specific embodiment of the utility model as shown in Figure 1, high frequency induction welding compressing head specify into

(3) guide rod 3: play connection and guide effect, guide rod resets, and guide springs is compressed and answer, prevents that spring is multi-direction stressed, deformation failure.Material is the 45# steel, modulation treatment, and fine finishining, surface roughness reaches Ra0.4;
(4) the guide rod back-moving spring 4: elastic connecting element.Material is common spring steel;
(5) bulb 51: the connection effect is fixed on through being threaded on the water-cooled pressure head, and is connected 25 ° of peak excursion guide rod angles with the ball pivot groove 31 of guide rod with the mode of ball pivot.Material is the 45# steel, modulation treatment, and fine finishining, surface roughness reaches Ra0.4;
(6) the water-cooled pressure head 6: workpiece, and its fixed contact effect, hollow is flowing water chamber 61, water-cooled pressure head sidewall is provided with water inlet 62 and delivery port 63, the water flowing cooling.Material is asked the red copper into T2, working face fine finishining, surface roughness Ra 0.4 ~ Ra0.8;
In addition, the high contact site of parts relative motion frequency adds less amount of lubrication oil in the assembling process, totally three places: guide rod and fixed handle contact site, guide rod and bulb contact site, bulb and sleeve contact site.
Parts are seen accompanying drawing in detail.
Fig. 2 is a probe of contactor welding sketch map, and welding material is:
