Abstract
The utility model discloses a T-type welding nut which comprises a cylinder with a T-type head. Inner threads are machined in an inner hole of the cylinder, and the T-type welding nut is characterized in that a plurality of spherical-surface-shaped point protrusions are arranged on the end face of the outer side of the T-type head, the heights of the spherical-surface-shaped point protrusions are 1.5mm-2mm, and the spherical-surface-shaped point protrusions are formed by the end face of the inner side of the T-type head in a stamping mode. The T-type welding nut is simple in structure, reasonable in design and capable of guaranteeing welding quality and strength after pressure welding is carried out between the T-type welding nut and an automobile door steel plate.
Description
Technical field
The utility model relates to and a kind ofly directly carry out the T type welded nut that pressure welding is welded with the vehicle door steel plate.
Background technique
Installed inside at vehicle door has some Switch for door and window parts, the common screw-thread securing of these Switch for door and window parts is on welded nut (comprising T type welded nut), the outside end face of welded nut and vehicle door steel plate carry out the pressure welding welding then, but because be that the whole outside end face of welded nut contacts with the car door steel plate, often produce that the pressure welding welding quality is relatively poor, the not high deficiency of weld strength.
Summary of the invention
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of simple in structure reasonable in design, carry out the pressure welding welding with the vehicle door steel plate after, can guarantee the T type welded nut of welding quality and intensity.
The utility model is implemented by the following technical programs:
T type welded nut comprises the cylindrical body of being with T-shape head, and cylindrical endoporus is processed with internal thread, it is characterized in that: the outside end face of T-shape head is provided with a plurality of spherical shape point projectioies.The height of spherical shape point projection is 1.5-2mm.
The T type welded nut that the utility model provides, the outside end face of T-shape head rationally arranges a plurality of spherical shape point projectioies, when pressure welding front T type welded nut is close to the vehicle door steel plate, have only the spherical shape point projection of T type welded nut to contact with the vehicle door steel plate, after carrying out the pressure welding welding like this, just can guarantee quality and the intensity of welding.
Spherical shape point projection is formed by punching press T-shape head inner side end.Technique scheme makes the preparation process of T type welded nut simple first, second effectively reduces cost.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structural drawing of the present utility model,
Fig. 2 is the directional diagram of overlooking of Fig. 1,
Fig. 3 is the directional diagram of overlooking of Fig. 2.
Embodiment
Describe relevant details and the working principle of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
As shown in the figure, T type welded nut of the present utility model, comprise the cylindrical body 2 of being with T-shape head 1, the endoporus of cylindrical body 2 is processed with internal thread, the outside end face of T-shape head 1 is provided with 3, four spherical shape point projectioies of four spherical shape point projectioies, 3 four jiaos of layouts at T-shape head 1 outside end face, and the height of spherical shape point projection 3 is 1.5-2mm, spherical shape point projection 3 is formed by punching press T-shape head 1 inner side end, puts protruding 3 corresponding punching press shrinkage pools 4 so leave four at the inner side end of T-shape head 1 with spherical shape.
