Description
[technical field]
The utility model relates to the technical field of auto parts machinery, particularly a kind of technical field of welded nut.
[background technique]
Welded nut is a kind of nut being applicable to welding at nut outward, generally that welding material is made and thicker suitable and weld, welding is equivalent to two separation members to become an entirety, cool admixed together after metal melt again with high temperature, centre can add alloy, inside is the effect of molecular force, and intensity is generally large than parent intensity.The experiment of welding parameter will see the fusion size of weld seam, according to fusion size adjustment welding parameter, until eliminate defect.The quality of certain welding quality is relevant with pre-welding treatment, deashing, oil stain etc.It is comparatively large that welded nut has strength ratio, the advantages such as using scope is wide, and thin and thick can; but because high temperature can cause connected piece to be out of shape, and non-dismountable, and some active metals can not be welded by usual method; such as aluminium; magnesium etc., need protection gas or argon arc welding, require processing technology and precision; existing a kind of automobile-used welded nut fixing for automobile safety belt clasp; by nut-welding on car door, clasp is fixed on nut by screw rod, realizes fixing.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of cubic welded nut, and structure is simple, and easy for installation, good fixing effect, reduces the temperature distortion of screw thread ingress.
For achieving the above object, the utility model proposes a kind of cubic welded nut, comprise nut body and annular protrusion, described nut body is square structure, described annular protrusion is arranged at the upper end of nut body, annular protrusion and nut body are integral type structure, the central axis of described nut body and the central axis of annular protrusion overlap, the center of described nut body offers tapped hole, described tapped hole runs through whole nut body and annular protrusion, it is excessive that the opening of tapped hole is provided with chamfering, the lower surface of described nut body is also provided with solder-bump, the sectional shape of solder-bump is trapezoidal.
As preferably, the quantity of described solder-bump is 4, and solder-bump is distributed on four angles of nut body outer rim, and solder-bump and nut body are formed in one structure.
As preferably, the lower surface of described nut body is concave surface, can reduce the temperature distortion of the screw thread ingress when welding.
As preferably, the outer place of described nut body and solder-bump is equipped with rounding.
The beneficial effects of the utility model: the utility model structure is simple, easy for installation, solder-bump is evenly distributed on four angles of nut body, the sectional shape of solder-bump is trapezoidal, weld strength is high, even during welding, reciprocally do not remove and install after having welded, join strength is high, and by the lower surface of nut body is set to concave surface, concave surface provides certain space, during welding, heat affected zone avoids screw thread place, and compared with plane, concave surface effectively can reduce the temperature distortion of the screw thread ingress when welding.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the plan structure figure of a kind of cubic welded nut of the utility model;
Fig. 2 is the left TV structure figure of a kind of cubic welded nut of the utility model.
In figure: 1-nut body, 2-annular protrusion, 3-tapped hole, 4-solder-bump, 5-rounding.
[embodiment]
Consult Fig. 1, Fig. 2, a kind of cubic welded nut of the utility model, comprise nut body 1 and annular protrusion 2, described nut body 1 is square structure, described annular protrusion 2 is arranged at the upper end of nut body 1, annular protrusion 2 and nut body 1 are integral type structure, the central axis of described nut body 1 and the central axis of annular protrusion 2 overlap, the center of described nut body 1 offers tapped hole 3, described tapped hole 3 runs through whole nut body 1 and annular protrusion 2, it is excessive that the opening of tapped hole 3 is provided with chamfering, the lower surface of described nut body 1 is also provided with solder-bump 4, the sectional shape of solder-bump 4 is trapezoidal, the quantity of described solder-bump 4 is 4, solder-bump 4 is distributed on four angles of nut body 1 outer rim, solder-bump 4 and nut body 1 are formed in one structure, the lower surface of described nut body 1 is concave surface, described nut body 1 is equipped with rounding 5 with the outer place of solder-bump 4.
Utility model works process:
A kind of cubic welded nut of the utility model in the course of the work, be mainly used in the automobile-used welded nut that automobile safety belt clasp is fixing, by nut-welding on car door, seat-Belt-Buckled is fixed on nut by screw rod, realize fixing, the lower surface of wherein nut body 1 is provided with solder-bump 4, lower surface is face of weld, the lower surface of nut body 1 is concave surface, the setting of concave surface provides certain space, during welding, heat affected zone avoids screw thread place, compared with plane, flat thread is heated yielding, screw thread specification is difficult to pass through, concave surface can reduce the temperature distortion of the screw thread ingress when welding, further, nut body 1 is equipped with rounding 5 with the outer place of solder-bump 4, effectively can reduce the outflow of welding slag during welding, solder-bump 4 is evenly distributed on four angles of nut body 1, the sectional shape of solder-bump 4 is trapezoidal, weld strength is high, even during welding, during welding, four solder-bump 4 fusings are combined with workpiece, realize fixing, reciprocally do not remove and install after having welded, join strength is high.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
