Abstract
The invention discloses a sheet metal part welding process, wherein a sheet metal part comprises a sheet metal part I and a sheet metal part II which are perpendicular to each other, a plurality of positioning holes are formed in the sheet metal part I, and insertion blocks which are inserted into the positioning holes are conveniently arranged on the sheet metal part II. According to the invention, the groove is additionally arranged at the edge of the positioning hole, redundant welding flux enters the groove during welding, the contact area between the two sheet metal parts is large, and the strength requirement can be met by the short crater.
Description
Technical Field
The invention belongs to the technical field of sheet metal processing, and relates to a sheet metal part welding process.
Background
Generally can adopt the welding position structure between two sheet metal components, the lug that the sheet metal component edge set up has realized the location of two sheet metal components in inserting the locating hole that sets up in another sheet metal component. The joint of the two sheet metal parts is welded in a spot welding mode, and a weld crater formed by spot welding needs to be polished to be smooth. The gap between the sheet metal component is less, in order to guarantee welding strength between the two, need prolong the crater, not only influences the welding outward appearance of sheet metal component, has still increased for a long time polishing.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the welding process capable of not only ensuring the welding strength of the sheet metal part, but also ensuring the welding appearance of the sheet metal part is improved.
In order to achieve the purpose, the technical scheme provided by the invention is as follows:
a sheet metal part welding process is characterized in that a sheet metal part comprises a first sheet metal part and a second sheet metal part which are perpendicular to each other, a plurality of positioning holes are formed in the first sheet metal part, inserting blocks which are inserted into the positioning holes are conveniently arranged on the second sheet metal part, and outward grooves are formed in the edges of the positioning holes, which are located at two sides of the second sheet metal part; and before welding, the sheet metal part is flatly placed on a welding table, and then a supporting plate for covering the positioning hole is placed on one side of the first sheet metal part, which is opposite to the second sheet metal part.
The invention has the beneficial effects that: 1. the edge of the positioning hole is provided with the groove, redundant welding flux enters the groove during welding, the contact area between the two sheet metal parts is large, and the strength requirement can be met through the short crater; 2. the area of the crater on the surface of the sheet metal part is reduced, the appearance quality of the sheet metal part is improved, and the polishing time of the crater is shortened.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below.
FIG. 1 is a welding structure view of a sheet metal part of an embodiment;
fig. 2 is a structural view of the positioning hole of the embodiment.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The sheet metal part shown in fig. 1 comprises a first sheet metal part 10 and a second sheet metal part 20 which are perpendicular to each other, a plurality of positioning holes 30 are formed in the first sheet metal part, insertion blocks 40 which are inserted into the positioning holes are conveniently arranged on the second sheet metal part, and outward grooves 50 (see fig. 2) are formed in the edges of the positioning holes which are located on two sides of the second sheet metal part. Preferably, the shape of the groove is selected from the group consisting of a semi-circular shape, a continuous wave shape or a zigzag shape, a straight line shape or an oblique line shape according to the thickness of the sheet metal part and the sizes of the insert block and the positioning block hole.
The sheet metal part is placed on the welding table before welding, the supporting plate covering the positioning hole is placed on one side of the first sheet metal part relative to the second sheet metal part, and during welding, the welding flux cannot flow to the other side of the sheet metal part.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
Claims (5)
