Description
Technical field
The present invention relates to be used on a kind of electric spot-welding machine the welding head holder of clamping parallel pole soldering tip.
Background technology
The welding head holder of existing electric spot-welding machine as shown in Figure 1, adopt two metal derbies make welding head holder about two fixture block 1a, 1b, simultaneously as the two poles of the earth of welding head holder.Welding head holder is connected with the spot welder head slide-bar by the adapter sleeve 2 of insulation.Two fixture block correspondences respectively have semi-circular recesses 6a, a 6b at the welding head holder rear portion, and these two grooves constitute the circular hole 15 that adapter sleeve 2 is installed; The diameter of these two groove mid portions is bigger than two, a becket 7 is installed in it, adapter sleeve 2 passes this becket, there are corresponding two connecting screw 5a, 5b to twist on two screws of this becket on two fixture blocks, these two connecting screws can be withstood adapter sleeve 2, screw these two connecting screws can reach welding head holder two fixture blocks are connected to each other and with head slide-bar purpose of connecting.Two fixture block front end correspondences respectively have a semicircle clip slot 11a, 11b, and this two clip slot is in order to install clamping soldering tip (parallel pole).There is the screw 3 of dress compression spring in the front portion of welding head holder, and this screw runs through two fixture blocks, rotates this screw and can clamp or unclamp soldering tip (parallel pole).
Because electric spot-welding machine is with low-voltage, big current work, so require contacting of welding head holder and soldering tip (parallel pole) necessary good, reliable.And can see that from above-mentioned structure the main effect of connecting screw 5a, 5b is welding head holder to be connected with the head slide-bar and two fixture blocks are connected to each other by becket 7, screw 3 is to be used for clamping or unclamping soldering tip, so do not locate reliably between two fixture blocks about existing welding head holder, dislocation easily, particularly when screwing screw 3, be easy to cause between clip slot 11a, the 11b of welding head holder two fixture block front ends misplace, cause soldering tip and the loose contact of welding head holder the two poles of the earth; And its becket 7 outsides do not have insulating barrier, between becket 7 and the two fixture block inwalls sizable gap will be arranged, and when screwing connecting screw 5a, 5b, this becket 7 must keep unsettled state, otherwise can cause welding head holder two utmost point short circuits.Simultaneously, become complicated owing to the structure that becket 7 makes welding head holder will be set in the middle of two fixture blocks, processing and installation difficulty are bigger.In addition, do not have lighting source on the existing welding head holder, need to throw light on illuminating lamp in addition, because welded part is tiny, illuminating ray easily by shield, often needs to adopt the light source of bigger wattage when welding, both wasted energy, illuminating effect is undesirable again, and illuminating lamp also takes up room in addition.
Summary of the invention
It is comparatively simple, reliable to the purpose of this invention is to provide a kind of structure, contacts good welding head holder for spot welder with soldering tip, to overcome the existing shortcoming of above-mentioned existing welding head holder.
Welding head holder for spot welder of the present invention, the adapter sleeve of two fixture blocks, insulation, connecting screw and soldering tip parbuckle screw about comprising; Adapter sleeve is loaded in the circular hole at welding head holder rear portion, and connecting screw is passed fixture block from the side, withstands adapter sleeve; Respectively there is a symmetrical mutually clip slot two fixture block front end inboards; The soldering tip parbuckle screw passes a fixture block from the side in the welding head holder front portion, twists on the corresponding screw of another fixture block again.Be provided with the insulated dowel of stablizing left and right sides fixture block relative position at the welding head holder middle part.One fixture block posterior medial has a projection (this projection is semicircular arc or other arc preferably), and another fixture block has a groove that matches with this projection, and the circular hole that is used to install adapter sleeve on the welding head holder is located in this high spot.One connecting screw is passed the fixture block of band projection from lateral surface, withstands adapter sleeve; Another connecting screw is passed another fixture block from lateral surface and is twisted on this projection, is with insulation sleeve on this connecting screw.
Welding head holder of the present invention has improved the syndeton between two fixture blocks, and between two fixture blocks, increased insulated dowel, so, has reliable location between two fixture blocks of welding head holder of the present invention, clip slot in the use on two fixture blocks is difficult for misplacing, and has guaranteed that effectively welding head holder contacts well with soldering tip two utmost points.Simultaneously,, make structure comparatively simple, be easy to processing and installation owing to saved the becket that existing welding head holder is used to connect two fixture blocks.
Welding head holder of the present invention can also about be installed on two low-power lightings on two fixture blocks.The main shaft of these two little illuminating lamps is intersected on the soldered thing of soldering tip below.These two little illuminating lamps can lay respectively at the dual-side of welding head holder front end soldering tip.Can add collective lens in small-sized photograph bright lamp the place ahead in case of necessity.Little illuminating lamp can be light emitting diode (LED) or general miniature bulb.
Little illuminating lamp directly is set on welding head holder, does not need independent lighting source in addition, do not take up room, and light source is nearer from soldered thing, adopts low-voltage power supply, and power is less than one watt, to the existing enough illumination of soldered thing, use energy-conservation, safety, convenience.Shine owing to adopting two little illuminating lamps to intersect simultaneously, so light is relatively concentrated, is difficult for though the power of little illuminating lamp is little, being guaranteed that still soldered thing has good illumination by shield.
The invention will be further described below in conjunction with accompanying drawing.
