Abstract
The utility model discloses a stud welding gripping head which comprises a hollow gripping head body. The rear part of the gripping head body is an installation part, the front part of the gripping head body is a clamping part which is axially provided with an elastic groove, the periphery of the clamping part is provided with a groove, and an elastic clamping element which is a metal elastic clamping element is arranged in the groove. The metal elastic clamping element is difficult to age under the environment of high temperature welding and can keep clamping force for a long term, and the installation part can not influence the normal use of the stud welding gripping head because of damage caused by welding fire strike if the installation part adopts column surface clamping to replace thread tightening. The utility model greatly prolongs the service life of the stud welding gripping head and lowers the production cost.
Description
[technical field]
The utility model relates to stud welding gun, relates in particular to the easily worn part of stud welding gun, the arc stud welding chuck.
[background technology]
All need a large amount of welding screws (perhaps being called screw) on the sheet metal component in a plurality of industries such as five metals, automobile, shipbuilding, aircrafts, in welding process, have one to be used for the clamping double-screw bolt in the welding gun, and the general easily worn part of conduction welding current, the arc stud welding chuck.In welding process, because welding current is very big, operating temperature height, arc stud welding chuck are easy to damage.Now the connecting portion of the general arc stud welding chuck that uses adopts helicitic texture, and just the place that links to each other with welding gun of arc stud welding chuck generally is threaded.The arc stud welding chuck needs conduction, generally uses the red copper manufacturing, and the elasticity deficiency is in the local chucking power of rubber o-ring with the raising chuck that generally all adopt of chuck clamping nail.Above-mentioned weld clip head is struck sparks between connecting thread under the situation that employing is threaded easily, and connecting thread is damaged.Because 0 type circle is a rubber, at high temperature is easy to wear out, weld clip head clamping force is descended, these all make chuck reduce greatly service life.
[summary of the invention]
The technical problems to be solved in the utility model provides a kind of arc stud welding chuck of long service life.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of arc stud welding chuck, the chuck body that comprises hollow, the rear portion of chuck body are installation portion, the front clamp portion of chuck body, the clamping section has elastic groove vertically, the periphery of clamping section is fluted, and resilient gripping member is housed in groove, and described resilient gripping member is the metallic elastic clamping element.
Above-described arc stud welding chuck, described metallic elastic clamping element can be a cylindrically coiled spring.
Above-described arc stud welding chuck, described metallic elastic clamping element can be a split ring.Described split ring can be the jump ring that wire is done.It also can be the collar that metal tape is done.The opening of described collar can be that the herringbone mouth also can be an angle.
Above-described arc stud welding chuck, described metal can be the spring steel or stainless steels.
Above-described arc stud welding chuck, the periphery of described installation portion is preferably the face of cylinder.
Resilient gripping member of the present utility model is the metallic elastic clamping element, also is difficult for wearing out under the environment of welding high temperature, can keep clamping force for a long time, has improved the service life of arc stud welding chuck greatly, has reduced production cost.
Installation portion of the present utility model replaces screw thread to fix as clamping with the face of cylinder, and installation portion can not cause the normal use that screw thread damages influences the arc stud welding chuck, longer service life because of the welding sparking again.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the parts explosion that the real arc stud welding chuck of the utility model is executed example 1.
Fig. 2 is the installation diagram that the real arc stud welding chuck of the utility model is executed example 1.
Fig. 3 is the installation diagram that the real arc stud welding chuck of the utility model is executed example 2.
Fig. 4 is the installation diagram that the real arc stud welding chuck of the utility model is executed example 3.
[specific embodiment]
In Fig. 1, the utility model arc stud welding chuck embodiment 1 shown in Figure 2, comprise spring collar 1, hollow chuck body 2, nut 3, locking nut 4, adjust screw rod 5.The front portion of chuck body 2 is the clamping section, and the rear portion is an installation portion.The clamping section has 4 narrow grooves of elasticity vertically, and outwards open the clamping section when being convenient to the double-screw bolt insertion.The periphery of clamping section front end has 1 circle groove, is used for mounting spring collar 1.Spring collar 1 is enclosed within the groove the inside of chuck body 2, and spring collar 1 is the open annular collar that stainless steel band is done, and the opening of collar 1 can be the herringbone mouth, angle or straight mouth, and present embodiment has adopted the herringbone mouth.Nut 3 is fixed in the screwed hole of chuck body 2 installation portions, adjusts screw rod 5 and is screwed in the screwed hole of nut 3, and lock with locking nut 4.Be screwed into or back-out and adjust screw rod 5 and can adjust the length that double-screw bolt inserts, to adapt to the weldering nail of different length.The annular opening collar that stainless steel band is done can not keep clamping force because of high temperature ageing loses elastic force for a long time under the environment of welding high temperature, improved the service life of arc stud welding chuck, has reduced production cost.
As depicted in figs. 1 and 2, the periphery of present embodiment chuck body 2 installation portions is the face of cylinder, clamping replacement screw thread of the prior art with the face of cylinder fixes with welding gun, installation portion can be not again during because of welding sparking cause the screw thread damage to influence the normal use of arc stud welding chuck, arc stud welding chuck longer service life.
In the utility model arc stud welding chuck embodiment 2 shown in Figure 3, the periphery of the clamping section front end of chuck body 2 has 2 circle grooves, is used for installing 2 spring steel wires respectively and makes opening jump ring 6.Jump ring 6 is enclosed within the groove the inside of chuck body 2, to increase the clamping force of arc stud welding chuck clamping section.
In the utility model arc stud welding chuck embodiment 3 shown in Figure 4, being with the metallic elastic clamping element in the clamping section front end peripheral groove of chuck body 2 is that spring steel wire is made cylindrically coiled spring 7, and the radical elasticity when utilizing cylindrically coiled spring 7 expanded in diameter increases the clamping force of arc stud welding chuck clamping section.
Among the above embodiment, the material of metallic elastic clamping element is the spring steel or stainless steel, and certainly, other have favorable elasticity, resistant to elevated temperatures metal material to use.
