Abstract
The utility model discloses a car body sheet metal part projection welding spot structure which comprises a plate body (1). One or more projection welding holes (2) are formed in the plate body (1). Two or three projection spots (3) which are evenly distributed along the circumference are arranged on the periphery of each projection welding hole (2). The circle centers of the circumferences defined by the projection spots (3) are in the center lines of the projection welding holes (2). The projection spots (3) project out of the plate face of the plate body (1). According to the car body sheet metal part projection welding spot structure, the projection spots are arranged on a car body sheet metal part, a standard part without projection spots or with small projection spots can be welded, firm welding of the standard part can be ensured, and the car body sheet metal part projection welding spot structure has the advantages of being ingenious in concept, simple in structure, easy to implement and the like.
Description
Technical field
The utility model belongs to the car technical field, specifically, and the particularly projection welding dot structure of motorcar body sheet metal component.
Background technology
At present, operated by rotary motion has the projection welding hole on the Metal Sheets for Body-manufacturing of car so that on the projection welding hole tender such as project-welding nut, be used for the assembly connection to the vehicle body particular elements.The periphery surface in existing projection welding hole all is smooth, does not have salient point or salient point tender less than normal to be difficult for welding for projection welding.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of motorcar body sheet metal component projection welding dot structure, does not have salient point or salient point tender less than normal with welding.
The technical solution of the utility model is as follows: a kind of motorcar body sheet metal component projection welding dot structure, comprise plate body (1), have one or more projection weldings hole (2) at plate body (1), around described projection welding hole (2), be provided with the salient point (3) that two or three distribute by even circumferential, the center of circle of described salient point (3) circumference that surrounds is on the line of centers of projection welding hole (2), and this salient point (3) protrudes from the plate face of plate body (1).
The utility model arranges salient point at the sheet metal component of motorcar body, this salient point is positioned at the periphery in projection welding hole, like this for salient point being arranged or do not have the tender of salient point all can weld, and can make things convenient for salient point tender less than normal to weld, can guarantee the fixing of salient point tender welding less than normal.
In order to make things convenient for processing and manufacturing, when improving work efficiency, reduce production costs, described salient point (3) and projection welding hole (2) form by mould punching, form pit at the back side of salient point (3).
As preferably, the height that described salient point (3) protrudes from plate body (1) is 1-2mm.
Salient point is too near apart from the projection welding hole, not only bad for processing, and easily causes the projection welding bore deformation; Salient point is too far away apart from the projection welding hole, and tender can not occur to contact with salient point, so do not have corresponding effect.Therefore, the distance between the hole wall of described salient point (3) and projection welding hole (2) is 1.5-6.5mm.
For reduced proper motion, be convenient to processing, described salient point (3) is circular.
Beneficial effect: the utility model arranges salient point at Metal Sheets for Body-manufacturing, and can weld does not have salient point or salient point tender less than normal, and can guarantee that tender welding is firm, have be skillfully constructed, simple in structure, implement the characteristics such as easy.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the Metal Sheets for Body-manufacturing of car can be fender guard, rear quarter panel, engine bonnet, floor, mudwing etc., and this Metal Sheets for Body-manufacturing has plate body 1, has one or more projection weldings hole 2 at plate body 1.Number and the position in the moulding of described plate body 1, projection welding hole 2 are prior art, do not do at this and give unnecessary details.Be provided with two or three salient points 3 around described projection welding hole 2, this salient point 3 is formed on the plate body 1, and these two or three salient points 3 are pressed even circumferential and distributed, and the center of circle of described salient point 3 circumference that surrounds is on the line of centers in projection welding hole 2.
As shown in Figure 1 and Figure 2, described salient point 3 and projection welding hole 2 is by the mould punching one-shot forming, and this salient point 3 is preferably circle, and salient point 3 protrudes from the plate face of plate body 1, and the diameter of salient point 3 maximums is 1.5-3.5mm.The height that described salient point 3 protrudes from plate body 1 is 1-2mm, and the present embodiment is preferably 1.5mm, forms pit at the back side of salient point 3.Described salient point 3 is positioned at the orthogonal projection zone of tender to be welded on plate body 1, and the distance between the hole wall in salient point 3 and projection welding hole 2 is 1.5-6.5mm.
Claims (5)
1. motorcar body sheet metal component projection welding dot structure, comprise plate body (1), have one or more projection weldings hole (2) at plate body (1), it is characterized in that: around described projection welding hole (2), be provided with the salient point (3) that two or three distribute by even circumferential, the center of circle of described salient point (3) circumference that surrounds is on the line of centers of projection welding hole (2), and this salient point (3) protrudes from the plate face of plate body (1).
2. motorcar body sheet metal component projection welding dot structure according to claim 1, it is characterized in that: described salient point (3) and projection welding hole (2) form by mould punching, form pit at the back side of salient point (3).
