Description

Technical Field

[0001] This utility model relates to the field of hardware product manufacturing technology, and more specifically to a welding device for hardware product manufacturing. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding utilizes a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can be performed in various environments. However, welding can pose dangers to operators regardless of location, so appropriate protective measures must be taken when welding.

[0003] Inadequacies of existing technology: The presence of stains, grease, rust, or other impurities on the welding surface can hinder the formation of the weld pool, leading to weak welds. Especially at high temperatures, these impurities may contaminate the weld metal, causing porosity, cracks, or inclusions, thereby reducing weld quality. Failure to clean weld slag can easily lead to overheating or blockage of the equipment. In particular, when the high-temperature weld pool is in contact with the cooling system, weld slag may clog the cooling pipes or cause excessive wear of the welding electrode, thus affecting the normal operation of the equipment.

[0024] Among them, a connecting rod 107 is fixedly connected to the side of the grinding rod 101, a follower plate 106 is fixedly connected to the side of the connecting rod 107, a V-shaped rotating rod 108 is fixedly connected to the bottom end of the follower plate 106, and the bottom end of the V-shaped rotating rod 108 is fixedly connected to the side of the fixing ring 109.

[0025] The welding removal mechanism 2 includes an outer fixed frame 201 and a rotating disk 203. A micro motor 202 is fixedly connected to the side of the outer fixed frame 201. A rotating rod 204 is fixedly connected to the bottom of the micro motor 202. The side of the rotating rod 204 is connected to the inner side of the rotating disk 203. The side of the rotating disk 203 is fixedly connected to the side of the outer fixed frame 201.

[0026] The rotating rod 204 is connected to a connecting rod 205 on its side. The bottom end of the connecting rod 205 is fixedly connected to an assist rod 206. The bottom end of the assist rod 206 is fixedly connected to a hammer rod 207. The side of the hammer rod 207 is fixedly connected to a buffer plate 208. The side of the outer fixed frame 201 is fixedly connected to the inner side of the moving mechanism 3.

[0027] The outer fixed frame 201 has a rotating groove 211 on its side. The inner side of the rotating groove 211 is connected to the side of the rotating rod 204. The inner side of the outer fixed frame 201 is fixedly connected to a limiting plate 209. The bottom end of the limiting plate 209 is fixedly connected to a spring 210. The inner side of the spring 210 is connected to the side of the buffer plate 208.

[0028] The moving mechanism 3 includes a welding head 301 and a load-bearing plate 304. The side of the welding head 301 is fixedly connected to the inner side of the load-bearing plate 304. A welding wire 302 is fixedly connected to the bottom of the welding head 301, and a mechanical rod 303 is fixedly connected to the top of the welding head 301.

[0029] The top of the load-bearing plate 304 is provided with a fixing groove 305, and a grinding rod 101 is connected to the inner side of the fixing groove 305. The top of the load-bearing plate 304 is fixedly connected to the bottom of the rotary motor 102. The side of the load-bearing plate 304 is provided with a fixing slot 306, and the side of the fixing slot 306 is fixedly connected to the side of the outer fixing frame 201.

[0030] The working principle of this utility model is as follows: The side of the load-bearing plate 304 is moved by the top of the mechanical rod 303. Therefore, a grinding mechanism 1 is provided on one side of the welding head 301 to perform preliminary cleaning of the surface of the object contacted by the welding wire 302. A weld removal mechanism 2 is provided on the other side of the welding head 301 to hammer and clean the weld slag produced after the welding wire 302 is welded. During the movement of the welding wire 302, the grinding mechanism 1 is in front of it, while the weld removal mechanism 2 is behind it.

[0031] The rotary motor 102 is started to drive the grinding rod 101 to rotate. The side of the grinding rod 101 is connected to a follower disk 106 via a connecting rod 107. The follower disk 106 rotates around the grinding rod 101 in a circular motion. The V-shaped rotating rod 108 connected to the bottom of the follower disk 106 drives the grinding disk 105 at its bottom to swing. The V-shaped rotating rod 108 is connected to the side of the fixed rod 110 via a fixing ring 109. The top of the fixed rod 110 is fixedly connected to the inner side of the grinding disk 105. Therefore, the V-shaped rotating rod 108 will drive the grinding disc 105 to swing. However, a U-shaped rotating rod 104 is connected to the side of another fixed rod 110 of the grinding disc 105. The U-shaped rotating rod 104 is fixedly connected to the side of the bearing 103, but it does not rotate with the rotation of the grinding rod 101. Therefore, it has a certain directional restriction effect on the swing of the grinding disc 105. Thus, the interaction between the follower disc 106 and the U-shaped rotating rod 104 enables the grinding disc 105 to clean the surface of the workpiece to be welded.

[0032] After welding with welding wire 302, the micro motor 202 is started to drive the rotating rod 204 to rotate. The connecting rod 205 connected to the edge of the rotating rod 204 makes a circular motion on the side of the rotating disk 203 and pulls up and lowers the assist rod 206, which drives the hammering rod 207 to reciprocate on the inner side of the outer fixed frame 201 and knocks off the welded position. The buffer disk 208 is fixed in the middle of the elastic spring 210 to buffer the movement of the hammering rod 207, which can effectively neutralize the impact force when the micro motor 202 rotates quickly.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
