Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and in particular to a welding stud anti-splash device. Background Technology

[0002] Welding studs are a type of fastener that connects to the parent component through welding. The welding principle is as follows: First, an electric arc is ignited between the stud and the workpiece. After the stud and the workpiece are heated to a suitable welding temperature, the stud is fed into the weld pool formed on the surface of the workpiece under the action of external force, and finally the welded joint is formed.

[0003] During the welding process, spatter that easily adheres to metal is generated. Therefore, a protective ring is usually placed on the welding area to prevent the spatter from spreading.

[0004] However, due to the high temperature of the welding process, the protective ring will stick to the workpiece. After welding, the protective ring needs to be broken and removed by hammering. Since the bottom of the protective ring is completely stuck to the workpiece, some adhesive residue will remain after it is removed, and it needs to be cleaned separately. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a welding stud anti-splash device.

[0006] The objective of this utility model can be achieved through the following technical solutions: A welding stud anti-spatter device includes: a main body, the main body being cylindrical, and a plurality of notches being provided at one end of the main body, the notches being arranged around the central axis of the main body.

[0007] In the above-mentioned anti-splash device for weld studs, the notches are three in number and are distributed at equal intervals on the main body.

[0008] In the above-mentioned anti-splash device for weld studs, the notch is triangular.

[0009] In the above-mentioned anti-splash device for welding studs, the main body has a backing part, which is a ring structure that gradually decreases in size from the outside to the inside.

[0010] In the above-mentioned anti-splash device for weld studs, the notch is provided on the abutment part.

[0011] In the above-mentioned anti-splash device for weld nails, the main body is made of high-temperature resistant ceramic.

[0012] In the above-mentioned anti-splash device for weld studs, the high-temperature resistant ceramic is alumina ceramic or silicon nitride ceramic.

[0013] In the above-mentioned anti-splash device for weld studs, the end of the main body away from the notch has an annular support portion.

[0014] Compared with the prior art, this application has the following advantages: The main body is cylindrical, with several notches around the central axis at one end. This structural design directly reduces the contact area between the device and the workpiece. During the welding process, high-temperature spatter can still be blocked inside, but the reduced contact area between the main body and the workpiece makes it easier to clean the main body later. During cleaning, tools such as pry bars can be used to pry it open from the notches, and then it can be broken and removed to avoid the main body fragments sticking to the workpiece.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figures 1 to 2 As shown, a welding stud anti-spatter device includes: a main body 2, which is cylindrical, and a plurality of notches 22 are provided at one end of the main body 2, the notches 22 being arranged around the central axis of the main body 2.

[0018] The main body 2 is cylindrical, with several notches 22 opened around the central axis at one end. This structural design directly reduces the contact area between the device and the workpiece. During the welding process, high-temperature spatter can still be blocked inside, but the contact area between the main body 2 and the workpiece is reduced, which facilitates the subsequent cleaning of the main body 2. During cleaning, tools such as pry bars can be used to pry it open from the notches 22, and then break it to remove it, so as to avoid the fragments of the main body 2 sticking to the workpiece.

[0019] Specifically, there are three gaps 22 that are evenly spaced on the main body 2.

[0020] The three symmetrically distributed contact areas can be pried open from any of the notches 22 during the peeling process. The external force can be quickly transmitted to each adhesive part through the symmetrical structure, easily destroying the adhesive interface.

[0021] Specifically, gap 22 is triangular in shape.

[0022] Specifically, the main body 2 has abutment portion 21, which is a ring-shaped structure that gradually decreases in size from the outside to the inside. This ring-shaped structure is as follows: Figure 2 As shown, it presents a reduced structure of a curved surface, with an internal curved guide structure.

[0023] After the splashes appear, the ring structure can be used to guide the splashes to the upper part of the main body 2, reducing the adhesion between the splashes, the main body 2, and the workpiece, and making it easier to remove the main body 2.

[0024] Specifically, the notch 22 is provided on the abutment part 21.

[0025] Specifically, the main body 2 is made of high-temperature resistant ceramic.

[0026] Specifically, the high-temperature resistant ceramic is either alumina ceramic or silicon nitride ceramic.

[0027] Specifically, the end of the main body 2 away from the notch 22 has an annular support portion 23.

[0028] This design can play a centering role when the main body 2 is fitted onto the welding stud, so that the welding stud is always in the middle position of the main body 2.

[0029] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0030] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0031] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0032] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from this utility model or exceeding the scope defined by the appended claims.
