Description

Technical Field

[0001] This invention relates to the field of welding technology for bucket components, and more specifically, to an intelligent welding device for loader bucket teeth. Background Technology

[0002] In construction machinery such as loaders and excavators, bucket teeth are usually installed at the front edge of the bucket to enhance its structural strength and improve soil breaking and digging efficiency. The bucket teeth are fixed to the cutting edge of the bucket by welding. Both are high-strength steel structural components. Due to the material characteristics, the heat treatment process of the bucket teeth and cutting edge is highly demanding during the welding process: sufficient preheating is required before welding to reduce welding stress and prevent cold cracking; after welding, heat preservation and slow cooling are required to improve the weld structure, eliminate residual stress, and ensure that the joint has sufficient mechanical properties and service life.

[0003] However, in existing technologies, the aforementioned preheating and heat preservation operations mostly rely on manual handheld high-temperature torches (such as oxyacetylene flames) for localized heating. This method has significant drawbacks: on the one hand, the heating efficiency is low and the temperature distribution is uneven, making it difficult to accurately control the preheating and heat preservation temperatures; on the other hand, the preheating, welding, and heat preservation processes are disconnected from each other, making it impossible to achieve continuous heat treatment of "welding and heat preservation simultaneously." Especially when the ambient temperature is low or the workpiece is large, the weld area is prone to hardening or microcracks due to rapid cooling, affecting the reliability of the bucket tooth connection. In addition, manual flame heating is labor-intensive, time-consuming, and poses safety hazards, making it difficult to meet the demands of modern engineering machinery maintenance and manufacturing for efficient, stable, and high-quality welding processes. Summary of the Invention

[0037] It also includes an electric slide rail 301, an electric slider 302, a bracket 303, an electric push rod 304, a push plate 305, and a canvas 306; two electric slide rails 301 are bolted to the inner center of the U-shaped groove plate 2; each electric slide rail 301 is slidably connected to an electric slider 302, and the two electric sliders 302 are fixedly connected to the H-shaped plate 3; two brackets 303 are fixedly connected to the lower side of the horizontal plate 5; each bracket 303 is fixedly connected to an electric push rod 304; the telescopic parts of the two electric push rods 304 are fixedly connected to the push plate 305, and the push plate 305 is embedded in the horizontal plate 5; a canvas 306 is fixedly connected to each side of the push plate 305, and each of the two canvases 306 is fixedly connected to an inclined plate 6, forming a storage groove through the barrier net 7, the push plate 305, and the canvas 306.

[0038] The barrier net 7 is made of flexible material.

[0039] The implementation process of this embodiment is as follows:

[0040] The following directions are Figure 1Using the perspective reference, the direction where the profile frame 1 is located is the front. The following rotations refer to perspective directions from front to back, from top to bottom, and from right to left.

[0041] When in use, the operator first places the intelligent welding device, which is intended for loader bucket teeth, in the required position, sets up the welding robot on the right side of the profile frame 1, connects an external power source to all components that require electric drive, and pours a large amount of perlite particles into the storage trough and collection box 8 formed by the net 7, push plate 305 and canvas 306.

[0042] The operator controls the hoisting equipment to place the cutting edge of the welded bucket tooth seat on the limiting grooves 6001 of the two inclined plates 6. The cutting edge is positioned by the limiting grooves 6001. Then, the operator controls the extension parts of the two electric push rods 4 to extend, which moves the horizontal plate 5, inclined plate 6, net 7 and cutting edge together upward, moving the cutting edge between the fixing grooves 10701 of the two clamping blocks 107. Then, the operator controls the extension parts of all the electric push rods 102 to extend, which moves the connecting block 103, ring 104 and clamping block 107, so that the two clamping blocks 107 move towards the middle on the connecting shaft 106. The cutting edge is clamped by the fixing grooves 10701 of the two clamping blocks 107. The operator controls the extension parts of the two electric push rods 4 to move the connected parts downward to reset. Then, the operator places the five bucket tooth seats in the left part of the cutting edge in sequence at equal intervals.

[0043] After the bucket tooth seats are placed, the electric slider 202 moves on the electric slide rail 201. The two electric sliders 202 drive the connecting plate 203, electric slide rail 204, electric slider 205, L-shaped plate 206, electric slide rail 207, electric slider 208, U-shaped plate 209, mounting block 210, servo motor 211, high-temperature flame gun 212, fixed base 213, sliding rod 214, frame plate 215, and elastic element 216 to move to the right, causing the frame plate 215 to contact the five bucket tooth seats. The five positioning grooves 21501 on the frame plate 215 restrict the five bucket tooth seats, while the two sliding rods 214 slide on the frame plate 215, forcing the two elastic elements 216 to compress. The high-temperature flame gun 21... 2. After moving to the top of the blade tooth seat, simultaneously control the output shafts of electric slider 205, electric slider 3 208, and servo motor 211 to operate, adjust the position and angle of the high-temperature flame gun 212 so that the nozzle of the high-temperature flame gun 212 is aimed at the area to be welded where the blade tooth seat and blade are facing upwards, and move along the trajectory of the five areas to be welded. During the movement, the high-temperature flame continuously sprayed by the high-temperature flame gun 212 cleans the residual oil stains in the area to be welded, and uses the high-temperature flame to cause the residual oil stains to undergo an oxidation reaction, so that they are quickly carbonized, burned and peeled off. At the same time, the high-temperature flame sprayed by the high-temperature flame gun 212 can also preheat the area to be welded between the five blade tooth seats and the blade, which is convenient for subsequent welding work.

[0044] After the five bucket tooth holders and the blade-facing areas to be welded are cleaned and preheated, the two electric sliders 202 are controlled to move the connected components and the high-temperature torch 212 to the left, moving the high-temperature torch 212 to the left of the bucket tooth holders, while the frame plate 215 remains in its original position, continuing to restrict the five bucket tooth holders. The welding robot is then controlled to weld the five bucket tooth holders and the blade-facing areas to be welded sequentially. After welding is completed, the welding robot is controlled to reset. Next, the two electric sliders 202 are controlled to reset the connected components, so that the frame plate 215 is no longer in contact with the five bucket tooth holders. Then, the output shafts of the two servo motors 105 are controlled to drive the connecting shaft 106, the clamping block 107, the bucket tooth holders, and the blades to rotate clockwise by 180 degrees, causing the welded side of the bucket tooth holders and blades to rotate to... The unwelded side is rotated downwards to face upwards. Then, the electric slider 4 302 is controlled to move to the right on the electric slide rail 4 301. The two electric sliders 4 302 drive the H-shaped plate 3, electric push rod 1 4, horizontal plate 5, inclined plate 6, net 7, and perlite particles to move to the right together, moving the horizontal plate 5 directly below the five bucket tooth seats. Then, the telescopic parts of the two electric push rods 1 4 are controlled to extend, driving the connected parts and perlite particles to move upwards together, so that the weld line between the bucket tooth seat and the blade plate facing downwards is embedded in the perlite particles. Then, the telescopic parts of the two electric push rods 3 304 are controlled to extend, driving the push plate 305, canvas 306, and perlite particles to move upwards together, so that the perlite particles are tightly attached to the weld line between the bucket tooth seat and the blade plate. The heat insulation properties of the perlite particles are used to keep the welded area between the bucket tooth seat and the blade plate warm.

[0045] Simultaneously, the output shafts of electric slider 1 (202), electric slider 2 (205), electric slider 3 (208), and servo motor 2 (211) are coordinated to drive the nozzle of the high-temperature flame gun 212 to clean and preheat the welding area on the other side of the bucket tooth seat and blade plate. After cleaning and preheating are completed, the welding robot is controlled to weld the upward-facing welding area of ​​the bucket tooth seat and blade plate. After welding is completed, the operator uses hoisting equipment to fix the welded bucket tooth seat and blade plate, and controls the retraction of the telescopic parts of all electric push rods 1 (4) and 3 (304), driving... The connected components are reset, and the welded bucket tooth seat and blade are placed into the collection box 8. The perlite particles in the collection box 8 continue to keep the welded bucket tooth seat and blade warm, allowing them to cool slowly and ensuring the quality of the weld. Thus, during the welding process of the bucket tooth seat, the perlite particles in the storage tank are pushed upward by the push plate 305 and the canvas 306 to keep the welded area between the bucket tooth seat and the blade warm, allowing the bucket tooth seat and blade to cool slowly and preventing the welded bucket tooth seat and blade from cracking or forming brittle and hard structures due to rapid cooling.

[0046] It should be noted that the two canvases 306 can restrict the movement of perlite particles, preventing them from flowing along the gap between the push plate 305 and the inclined plate 6 and coming under the push plate 305, thus affecting the normal contraction of the push plate 305.

[0047] Example 2: Based on Example 1, such as Figures 7-8 As shown, it also includes a fixed plate 307, a spring telescopic column 308, and a limiting plate 309; the fixed plate 307 is fixedly connected to the outer side of the left inclined plate 6; two spring telescopic columns 308 are fixedly connected to the fixed plate 307; the telescopic ends of the two spring telescopic columns 308 are jointly fixedly connected to the limiting plate 309, and the limiting plate 309 slides with the left inclined plate 6.

[0048] It also includes a fixed plate 310, an electric push rod 311, and a protective plate 312; the fixed plate 310 is fixed to the outside of the right inclined plate 6; two electric push rods 311 are fixed to the fixed plate 310; the telescopic parts of the two electric push rods 311 are jointly fixed to the protective plate 312, and the protective plate 312 is inserted into the right inclined plate 6; the protective plate 312 is located above the canvas 306; five equally spaced clearance grooves 31201 are provided on the protective plate 312.

[0049] The protective plate 312 is tilted.

[0050] The protective plate 312 is made of metal.

[0051] The implementation process of this embodiment is as follows:

[0052] Because the perlite particles are small in size, and after the horizontal plate 5, inclined plate 6, and net 7 move the perlite particles upwards, the left inclined plate 6 will come into contact with the blade, creating a gap between the blade and the net 7. When the perlite particles are subsequently pushed to insulate the bucket tooth seat and blade, some particles will fall through this gap. Furthermore, while the perlite particles are insulating one side of the bucket tooth seat and blade, the welding robot is simultaneously welding the other side. Spatter generated during welding will enter the perlite particles, compromising their insulation effect. Therefore, in As the horizontal plate 5, the inclined plate 6, and the netting 7 move upwards carrying the perlite particles, the sliding limiting plate 309 replaces the limiting groove 6001 of the left inclined plate 6. As the inclined plate 6 moves upwards, the limiting plate 309 comes into contact with the blade, forcing the limiting plate 309 to move downwards on the left inclined plate 6. The two spring telescopic columns 308 automatically compress, causing the two netting 7s to come into contact with the lower side of the blade, eliminating the gap between the netting 7 and the blade, preventing the perlite particles from falling out of the gap. Furthermore, the sliding limiting plate 309 also makes it easier for the operator to place the blade on the two inclined plates 6.

[0053] When the inclined plate 6 contacts the blade, the telescopic parts of the two electric push rods 311 are retracted, driving the protective plate 312 to move towards the blade, so that the protective plate 312 contacts the bucket tooth seat and the blade. The five clearance grooves 31201 of the protective plate 312 coincide with the five bucket tooth seats. The protective plate 312 protects the perlite particles in the horizontal plate 5, inclined plate 6 and net 7, preventing welding spatter from entering the perlite particles and maintaining the integrity of the insulation layer.

[0054] After the bucket tooth holder and the blade plate are welded, there is no need for operators to control the hoisting equipment to put the bucket tooth holder and the blade plate into the collection box 8. It is only necessary to control the extension and retraction parts of the two electric push rods 311 to push out, so that the protective plate 312 comes to the outside of the right inclined plate 6. Then, control the output shafts of the two servo motors 105 to drive the connected parts, the bucket tooth holder and the blade plate to rotate clockwise, so that the bucket tooth holder and the blade plate are tilted. Then, control the extension and retraction parts of all the electric push rods 102 to retract, so that the connected parts move and no longer hold the blade plate, so that it slides into the collection box 8 along the tilted protective plate 312 to continue to keep the bucket tooth holder and the blade plate warm.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
