[summary of the invention]
The technical problems to be solved in the utility model provides a kind of can the nail by the clamping retaining when nut welds, easily the screwed hole of nut is implemented to block, and can improve nut welding positioning accuracy, improves the nut weld clip head of welding quality.
Another technical problem to be solved in the utility model is the retaining nail that also will provide a kind of and above-mentioned nut weld clip head to be used.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of nut weld clip head comprises conducting rod and nut chuck, and conducting rod and nut chuck are for dividing a body structure, by being threaded; The rear portion of conducting rod is an installation portion, and the front portion of conducting rod is retaining nail chuck; Connect before and after the endoporus of nut chuck, the internal thread by its rear portion is fixed on the external screw thread at conducting rod middle part, and the retaining of the front portion of conducting rod nail chuck stretches in the endoporus of nut chuck, and the endoporus of nut chuck is greater than the external diameter of retaining nail chuck; Retaining nail chuck axially has a complex root resilient radial groove along periphery, and the diameter of anterior endoporus is less than by the internal diameter in weldering nut thread hole under free state.
Above-described nut weld clip head, described axial elasticity radially groove are 3 to 10, and be uniform along retaining nail chuck periphery.The front end of described retaining nail chuck endoporus has chamfering, and described retaining nail chuck middle part endoporus is greater than the diameter of anterior endoporus.
The retaining nail that is used with above-mentioned nut weld clip head comprises head and bar portion, and described head diameter is greater than by the external diameter of weldering nut thread, and described bar portion diameter is equal to or less than by the internal diameter in weldering nut thread hole, and the material of retaining nail is resistant to elevated temperatures insulating materials.The material of retaining nail is ceramic material preferably.The head of retaining nail is the truncated cone preferably, and the bar portion and the head of retaining nail have chamfering.
There is retaining nail chuck to be convenient in welded nut, insert the retaining nail in the nut chuck of the utility model nut weld clip head; clamp retaining nail bar portion with the retaining nail; the head of retaining nail blocks the screwed hole of nut, stops welding slag to be splashed to the internal thread of nut, and the internal thread of protection nut is injury-free.Simultaneously, the head of retaining nail can insert in the locating hole of sheet metal component nut is positioned, and has improved the positional precision of nut welding.

[specific embodiment]
To the utility model nut weld clip head embodiment 1 shown in Figure 4, nut weld clip head rubber-like copper alloy made comprises conducting rod 1 and nut chuck 2 at Fig. 1, and conducting rod 1 and nut chuck 2 are for dividing body structure, by being threaded.The rear portion of conducting rod 1 is an installation portion, is fixed on the conducting end group front end of welding gun by locking nut.The front portion of nut chuck 2 axially has a plurality of elastic grooves along periphery, and front end has the pit of placing nut 3, and when nut 3 was filled in pit, the front end that has the nut chuck 2 of elastic groove opened, and nut 3 is clamped.Connect before and after the endoporus of nut chuck 2, the internal thread by its rear portion is fixed on the external screw thread at conducting rod 1 middle part ground.The front portion of conducting rod enters in the endoporus of nut chuck for retaining nail chuck, retaining nail chuck, and its external diameter is not subjected to the restriction of nut chuck endoporus less than the endoporus of nut chuck when opening.Retaining nail chuck along periphery uniform axially have 6 resilient radial groove 1a, the front end of retaining nail chuck is divided into 6 lobe elastic clip 1b.The diameter of retaining nail chuck anterior endoporus under free state is less than the internal diameter that is welded nut 3 screwed holes.There is free cutter at retaining nail chuck middle part, and its endoporus is greater than the diameter of anterior endoporus, and anti-backstop nail inserts, and when elastic clip 1b opened, its rear portion interfered with the front end of retaining nail 4.
Retaining nail 4 with nut weld clip head is used comprises head and bar portion, and its head diameter is greater than the major diameter of thread that is welded nut 3, and its bar portion diameter is equal to or less than by the internal diameter of weldering nut 3 screwed holes.The retaining nail is made with resistant to elevated temperatures insulating materials such as ceramic material.In the endoporus that will keep off nail 4 insertion retaining nail chucks, all there is chamfering in the bar portion of retaining nail with the front end of retaining nail chuck endoporus.
The using method of present embodiment nut weld clip head and retaining nail is, conducting rod with nut weld clip head inserts welding gun earlier, use locking nut locked then, nut is packed in the nut chuck of nut weld clip head, and the retaining nail passes the retaining of nut thread hole and nut weld clip head and follows closely the chuck resilient engagement.Before the welding, nut by the welding gun band and retaining is followed closely towards the panel beating mother metal that is welded, has preset with retaining nail head suitable locating hole the position of welded nut on the panel beating mother metal, just can realize that with giving prominence in the locating hole that retaining nail head in the nut outside inserts sheet metal component nut is carried out precise coordinates locatees.During welding, welding gun nut by nut weld clip headband and is left the panel beating mother metal that is welded and carry out the starting the arc, though have welding slag to splash this moment, but it is mobile together that the retaining nail is adjacent to welded nut all the time in whole welding process, the retaining nail head pastes the threaded portion that covers nut eventually, the welding slag that splashes can not cause damage to the screw thread of nut, has guaranteed the quality of welding.The retaining nail is made with resistant to elevated temperatures insulating materials such as ceramic material, can be repeatedly used.
Among the utility model nut weld clip head embodiment 2 shown in Figure 5, the head of retaining nail is the truncated cone, is more convenient for inserting in the locating hole of sheet metal component.
