Description

Technical Field

[0001] This utility model belongs to the field of welding processing technology, and in particular relates to a welding wire conveying mechanism for overlay welding. Background Technology

[0002] Hardfacing is a process of depositing one or more layers of metal onto the surface of a part. It is widely used in many fields such as machinery manufacturing, metallurgy, mining, power, and petrochemicals. Through hardfacing, the surface hardness, wear resistance, corrosion resistance, heat resistance, and other properties of the parts can be improved.

[0003] A water-cooled spraying mechanism for wear-resistant steel plate surfacing refers to a device used to cool the surfacing area with water spraying during the surfacing process of wear-resistant steel plate surfacing.

[0004] In the use of existing equipment, because surfacing is a continuous welding process, welding wire needs to be continuously filled into the welding area to form a surfacing layer. If the welding wire is not continuously fed, the surfacing process may be interrupted due to the interruption of the welding wire supply, which may affect the continuity and efficiency of the surfacing work. Therefore, we provide a welding wire feeding mechanism for surfacing. Utility Model Content

[0005] The purpose of this utility model is to provide a welding wire feeding mechanism for surfacing welding. Through the feeding mechanism and clamping mechanism, it solves the problem that in the existing equipment, since surfacing welding is a continuous welding process, welding wire needs to be continuously filled into the welding area to form a surfacing layer. If the welding wire is not continuously fed, the surfacing process is likely to stop due to the interruption of the welding wire supply, which may affect the continuity and efficiency of the surfacing welding work.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a welding wire conveying mechanism for surfacing welding, including a base plate, a plurality of welding wire drums are fixedly connected to the top outer wall of the base plate, a rotating shaft is rotatably connected to the inner wall of the plurality of welding wire drums, an auxiliary platform is fixedly connected to the top outer wall of the base plate, and a conveying mechanism is provided on the outer wall of the welding wire drums.

[0008] The conveying mechanism includes several motor plates, the outer walls of which are fixedly connected to the outer wall of the welding wire drum. A motor is fixedly connected to the outer wall of the left-side motor plate, and a controller is fixedly connected to the outer wall of the left-side motor plate. The bottom output shaft of the motor is fixedly connected to a rotating shaft via a coupling. A second rotating shaft is rotatably connected to the inner wall of the motor plate, and a gear is fixedly connected to the outer wall of the second rotating shaft. A third rotating shaft is rotatably connected to the inner wall of the motor plate, and a second gear is fixedly connected to the outer wall of the third rotating shaft. The outer walls of the second gear mesh with the outer walls of the gear.

[0009] Furthermore, pulleys are fixedly connected to the outer walls of both the second and third rotating shafts, belts are driven to the outer walls of the pulleys, and conveyor blocks are fixedly connected to the outer walls of the belts.

[0010] Furthermore, a bevel gear is fixedly connected to the outer wall of the rotating shaft, and a second bevel gear is fixedly connected to the outer wall of the end of the rotating shaft near the motor plate. The outer wall of the second bevel gear meshes with the outer wall of the bevel gear, and a clamping mechanism is provided on the outer wall of the rotating shaft.

[0011] Furthermore, the clamping mechanism includes several support frames, the outer walls of the several support frames are fixedly connected to the outer wall of the rotating shaft, and the inner walls of the several support frames are rotatably connected to rotating blocks.

[0012] Furthermore, a worm gear is fixedly connected to the outer wall of the rotating block near the rotating shaft, and an auxiliary plate is fixedly connected to the outer wall of the rotating block away from the worm gear.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates gears to pull out one end of the welding wire from the welding wire hopper. The rotation of the gear drives the rotation of the second gear, which in turn drives the rotation of the bevel gear. The rotation of the rotating shaft feeds the welding wire, the rotation of the conveying block transports the welding wire, and the insulating protective tube guides the welding wire. This achieves a stable and continuous supply of welding wire, preventing the welding process from stopping due to interruption of the welding wire supply.

[0018] 2. This utility model incorporates a slide rail. The insulating protective tube is placed in contact with the surface of one end of the clamping block. Then, the worm gear is rotated, which drives the worm wheel to rotate. The rotation of the auxiliary plate causes the clamping blocks at both ends to slide in the sliding groove. The slide rail then moves the clamping blocks inward, clamping the insulating protective tube. This achieves stable positioning of the insulating protective tube and allows for convenient operation, avoiding the problem of complicated fixing operations affecting the workload of workers.

A rotating shaft 102 is rotatably connected to the inner wall of the several welding wire hoppers 101. An auxiliary platform 103 is fixedly connected to the top outer wall of the base plate 1. The rotating shaft 102 is rotated stably through the welding wire hoppers 101 to prevent the rotating shaft 102 from flipping over and causing the welding wire to become entangled. A conveying mechanism 2 is provided on the outer wall of the welding wire hopper 101.

[0030] The conveying mechanism 2 includes several motor plates 201. The outer walls of the motor plates 201 are fixedly connected to the outer wall of the welding wire hopper 101.

The position of the motor 202 is fixed by the motor plates 201, preventing the motor 202 from changing position during operation and causing damage. The bottom output shaft of the motor 202 is fixedly connected to a rotating shaft 204 via a coupling. A second rotating shaft 205 is rotatably connected to the inner wall of the motor plate 201. A gear 206 is fixedly connected to the outer wall of the second rotating shaft 205. A rotating shaft is rotatably connected to the inner wall of the motor plate 201. Gear 208 is fixedly connected to the outer wall of rotating shaft 207. The rotating shaft 205 rotates stably through motor plate 201, preventing it from falling off during rotation and causing the device to malfunction. The outer wall of gear 208 meshes with the outer wall of gear 206. Pulleys 209 are fixedly connected to the outer walls of both rotating shaft 205 and rotating shaft 207. A belt 210 is connected to the outer wall of pulley 209, and a conveyor block 211 is fixedly connected to the outer wall of belt 210. The rotation of gear 206 drives gear 208 to rotate, preventing gear 208 from affecting the rotation of gear 206 and causing the device to jam.

[0031] A bevel gear 212 is fixedly connected to the outer wall of the rotating shaft 204. A second bevel gear 213 is fixedly connected to the outer wall of the rotating shaft 102 near the motor plate 201. The outer wall of the second bevel gear 213 meshes with the outer wall of the bevel gear 212. A clamping mechanism 3 is provided on the outer wall of the rotating shaft 102. The clamping mechanism 3 includes several support frames 301. The rotation of the bevel gear 212 drives the second bevel gear 213 to rotate, preventing the second bevel gear 213 from affecting the rotation of the bevel gear 212 and causing the device to jam. The outer wall of each support frame 301 is fixedly connected to the outer wall of the rotating shaft 102. A rotating block 302 is rotatably connected to the inner wall of several support frames 301. A worm gear 303 is fixedly connected to the outer wall of the rotating block 302 near the rotating shaft 102, and an auxiliary plate 304 is fixedly connected to the outer wall of the rotating block 302 away from the worm gear 303. The support frame 301 enables the rotating block 302 to rotate stably, avoiding the problem of the rotating block 302 tilting during rotation, which would affect the normal use of the device.

[0032] The inner wall of the auxiliary plate 304 is provided with a sliding groove 305. A clamping block 306 is slidably connected to the inner wall of the auxiliary plate 304. An insulating protective tube 307 is slidably connected to the outer wall of the clamping block 306. A slide rail 308 is fixedly connected to the outer wall of the support frame 301 near the auxiliary plate 304. The position of the slide rail 308 is fixed by the support frame 301 to prevent the slide rail 308 from falling off during use and causing the device to malfunction. The inner wall of the slide rail 308 is slidably connected to the outer wall of the clamping block 306. A worm 309 is rotatably connected to the inner wall of the support frame 301 near the sliding groove 305. The outer wall of the worm 309 meshes with the outer wall of the worm wheel 303. The rotation of the worm 309 drives the rotation of the worm wheel 303, avoiding the worm wheel 303 from affecting the rotation of the worm 309 and causing the device to jam.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, first place the insulating protective tube 307 in contact with the surface of one end clamping block 306. Then, rotate the worm gear 309, which drives the worm wheel 303 to rotate. The worm wheel 303 drives the rotating block 302 to rotate, which in turn drives the auxiliary plate 304 to rotate. The rotation of the auxiliary plate 304 causes the clamping blocks 306 at both ends to slide in the sliding groove 305, and the sliding rail 308 moves the clamping blocks 306 at both ends inward. The movement clamps the insulating sheath 307, pulls out one end of the welding wire from the welding wire hopper 101, and brings it into contact with the surface of the conveyor block 211. Then, the controller 203 starts the motor 202, which causes the rotating shaft 204 to rotate. The rotating shaft 204 drives the lower left pulley 209 to rotate, which in turn drives the belt 210 to rotate. The belt 210 drives the lower right pulley 209 to rotate, which in turn drives the rotating shaft 205 to rotate. Shaft 205 drives gear 206 to rotate, which in turn drives gear 208 to rotate. Gear 208 drives left-side rotating shaft 207 to rotate, which in turn drives right-side upper pulley 209 to rotate. Right-side upper pulley 209 drives upper belt 210 to rotate, which in turn drives left-side upper pulley 209 to rotate. Left-side upper pulley 209 drives left-side rotating shaft 207 to rotate, and the upper and lower belts 210 move in opposite directions. 0 drives the conveyor block 211 to rotate, and at the same time the rotating shaft 204 drives the bevel gear 212 to rotate. The rotation of the bevel gear 212 drives the second bevel gear 213 to rotate, and the second bevel gear 213 drives the rotating shaft 102 to rotate. The rotation of the rotating shaft 102 is used to feed the welding wire, and the rotation of the conveyor block 211 is used to transport the welding wire. When the welding wire has completely passed through the belt 210 and there is an excess part, one end of the welding wire is inserted into the insulating protective tube 307, and the insulating protective tube 307 is used to guide the welding wire.
