Abstract
The utility model discloses a positioning core used for a lower electrode of an electric-resistance-welded bolt. A groove is formed on the outside surface of the positioning core. The groove engages with the fixed through-hole in the radial direction on the lower electrode. Accordingly, a screw is allowed to pass through the fixed through-hole on the lower electrode and then rest against the groove on the outside surface of the positioning core, thereby stabilizing the positioning core and preventing the positioning core from stripping off. When used for cleaning the welding slag, the insulating positioning core is effectively prevented from stripping off the lower electrode, facilitates the operation and the use, improves the welding efficiency and adapts to meet the requirement for welding techniques in the fast-developing automotive industry.
Description
Technical field
The utility model relates to a kind of electric resistance welding equipment element, relates in particular to a kind of location core that is used for electric resistance welding bolt bottom electrode.
Background technology
Electric resistance welding is to be a class welding method of the energy with the resistance heat, normally makes workpiece be under certain electrode pressure effect and the resistance heat that produced when utilizing electric current to pass through workpiece is realized connection with the fusing of the contact surface between two workpiece.Resistance welding technology has been widely used in every field, especially the auto industry aspect.Now, along with the fast development of automobile industry, resistance welding technology is also had higher requirement.When welded nut or bolt, in electric resistance welding bolt bottom electrode, all be with insulation location core, partly do insulation protection with double thread, prevent owing to shunting the spiral shell bud of burning.And in the process of carrying out electric resistance welding, can produce many welding slags usually, insulation location core is easy to detach the bolt bottom electrode when the cleaning welding slag, thereby has influenced operation and use, has reduced welding efficiency.Though its two arranged outside of bolt bottom electrode of prior art be radially fixed via, so that using screw to pass the outside that fixed via withstands insulation location core fixes, but still can not effectively solve the problem that insulation location core is deviate from, be difficult to adapt to and satisfy of the requirement of the auto manufacturing of fast development the welding aspect.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of location core that is used for electric resistance welding bolt bottom electrode of deviating from of can effectively preventing is provided, and with handled easily and use, improves welding efficiency.
The purpose of this utility model is achieved by the following technical programs:
A kind of location core that is used for electric resistance welding bolt bottom electrode that the utility model provides, its lateral surface has groove, and the fixed via that is radially on described groove and the bottom electrode is corresponding.Like this, use screw to pass the fixed via on the bottom electrode and withstand on the groove of location core lateral surface, just can the strong fix core, effectively prevent to locate deviating from of core.
Handle for ease of processing, the described groove of the utility model location core is the annular groove that is circumferential setting; Its section can be " V " shape, so as suitable with the bottom of fixed screw, thus more effectively improve fixed effect.
In addition, location described in the utility model core is the KCF pipe, and promptly the scheme of being taked is applicable to the KCF pipe.KCF is a kind of special ferrochrome, and its hardness and strength and toughness are good, has the characteristics of surperficial low-voltage insulation through special thermal treatment.And easy to process, the cycle is short.
The bolt bottom electrode that uses can comprise electrode lower body and electrode cap.The described groove of the utility model positioning chip can be corresponding with the fixed via on the bolt electrode lower body; Also can be corresponding with the fixed via on the bolt electrode cap.
The utlity model has following beneficial effect: when the cleaning welding slag, the location core that can effectively prevent to insulate is deviate from from bottom electrode, has made things convenient for operation and use, has improved welding efficiency, can adapt to and satisfy the requirement of fast-developing auto manufacturing to solder technology.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is the location core of the utility model embodiment;
Fig. 2 is to use the bolt electrode lower body of location shown in Figure 1 core;
Fig. 3 is to use the bolt electrode cap of location shown in Figure 1 core.
Among the figure: location core 1, groove 2, bolt electrode lower body 3, bolt electrode cap 4, fixed via 5
The specific embodiment
Fig. 1～Figure 3 shows that embodiment of the present utility model.Present embodiment location core 1 is the KCF pipe, and as shown in Figure 1, its lateral surface has the annular groove 2 that is circumferential setting.The position of this groove 2 can with 3 liang of outsides of bolt electrode lower body on be radially fixed via 5 corresponding (see figure 2)s; Also can with 4 liang of outsides of bolt electrode cap on be radially fixed via 5 corresponding (see figure 3)s.The section of groove 2 is " V " shape, so that suitable with the bottom of fixed screw.Use fixed screw to pass the fixed via 5 on bolt electrode lower body 3 or the bolt electrode cap 4 and withstand on the groove 2 of location core 1 lateral surface, just can strong fix core 1, thus effectively prevent to locate deviating from of core.
