Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to nut technical field, concretely is a kind of welded nut. BACKGROUND
[0002] Welded nut is a kind of nut directly welded on workpiece, the welded nut of prior art can be obviously seen weld point after being welded to workpiece, if not polishing, polishing or paint spraying etc. measures are carried out to weld point, the existence of weld point will cause the influence to the aesthetic property of workpiece, and polishing, polishing or paint spraying etc. Measures will increase production cost, it is difficult to meet processing demand. SUMMARY
[0003] The utility model discloses a kind of welded nuts, to solve the problems mentioned in the above background technology.
[0004] To achieve the above object, the utility model adopts the following technical scheme: the welded nut, including nut body, the one end of the nut body is provided with a sink, the section of the sink is inverted isosceles trapezoid, the inside of the sink is provided with annular weld, the weld has protrusion and overflow groove, the overflow groove is located in the inside of sink, the protrusion is conical, the protrusion has base and head, the base of the protrusion is located in the inside of sink, the head of the protrusion is located in the outside of sink.
[0005] Preferably, the sink is used to divide the end face of the one end of the nut into outer circle face and inner circle face, when the nut is placed on the ground and the opening of the sink faces upwards, the horizontal height of the inner circle face is lower than the horizontal height of the outer circle face.
[0006] Preferably, the inner circle face is matte.
[0007] Preferably, the protrusion is provided with multiple and is annularly arrayed.
[0008] Preferably, the overflow groove is located between two adjacent protrusions.
[0009] The utility model has the advantages that:
[0010] The nut body can hide weld point in sink after welding, so that weld point is avoided to be exposed outside nut body, to improve the aesthetic property of nut body after being welded to workpiece, and since polishing, polishing or paint spraying etc. Measures are not needed, so that cost can be saved, and use effect is good.

[0016] The specific embodiments of the present application will be further described below with reference to the accompanying drawings.
[0017] As shown in the drawings, Figures 1-4 a welded nut, comprising a nut body 1, one end of the nut body 1 is provided with a sink 2, the cross section of the sink 2 is an inverted isosceles trapezoid, the inside of the sink 2 is provided with an annular welding part, the welding part has a protrusion 3 and an overflow groove 4, the overflow groove 4 is located inside the sink 2, the protrusion 3 is conical, the protrusion 3 has a base and a head, the base of the protrusion 3 is located inside the sink 2, and the head of the protrusion 3 is located outside the sink 2.
[0018] When the nut body 1 is welded on the workpiece 7 by the welding machine, first, the workpiece 7 is placed on the operation platform of the welding machine, then the nut body 1 is placed on the workpiece 7, and the protrusion 3 on the nut body 1 is in contact with the surface of the workpiece 7, then the nut body 1 is welded on the workpiece 7 by the welding machine, the welding machine will exert a downward pressure on the nut body 1 during welding, the protrusion 3 will melt under the action of the current, the liquid generated after the melting of the protrusion 3 will enter the inside of the overflow groove 4 and the inside of the sink 2, and the liquid generated after the melting of the protrusion 3 is prevented from overflowing to the position outside the sink 2, so that after the nut body 1 is welded on the workpiece 7, the welding point is hidden in the sink 2, thereby improving the appearance of the nut body 1 after the welding is completed.
[0019] Further, the sink 2 is used to divide the end face of the nut into an outer ring surface 5 and an inner ring surface 6, when the nut is placed on the ground with the opening of the sink 2 facing upwards, the horizontal height of the inner ring surface 6 is lower than that of the outer ring surface 5, the liquid generated during the melting of the protrusion 3 can flow in the direction of the sink 2, the overflow groove 4 and the inner ring surface 6, and the area of the welding of the workpiece 7 and the nut body 1 is increased, the stability of the nut body 1 after welding is improved, and at the same time, the melted liquid is prevented from entering between the outer ring surface 5 and the workpiece 7, thereby improving the appearance of the nut body 1 after welding.
[0020] Further, the inner ring surface 6 is a matte surface, the contact area of the liquid generated after the melting of the protrusion 3 and the inner ring surface 6 is increased, and the stability of the welding of the nut body 1 is improved.
[0021] Further, the protrusions 3 are arranged in a plurality of annular arrays.
[0022] Further, the overflow groove 4 is located between two adjacent protrusions 3, so that the liquid generated after the melting of the protrusions 3 can flow in the direction of the overflow groove 4, thereby reducing the exposure of the welding points.
[0023] In the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
