Description

Technical Field

[0001] This utility model relates to the field of water-cooled bearing housing manufacturing technology, specifically a water-cooled bearing housing welding device. Background Technology

[0002] With the advent, upgrading, and use of machinery, bearings are increasingly being used for connecting shafts. As technology advances, bearings are also secured with bearing housings. A water-cooled bearing housing is a component used to support rotating shafts. Internally, it uses coolant to remove the heat generated by friction during bearing rotation, ensuring that both the bearing and housing maintain a suitable temperature range. This guarantees normal operation and lifespan of the bearing, allowing it to function normally even under harsh conditions. However, during the installation and fabrication of water-cooled bearing housings, stainless steel sealing plates need to be welded to the outer surface to enclose the cooling water channels and form a complete water-cooling system. During the welding process, defects such as pinholes and cracks can easily occur in the weld seams, affecting the processing and manufacturing quality of the water-cooled bearing housing. Utility Model Content

[0003] The purpose of this invention is to provide a water-cooled bearing housing welding device to solve the welding defects such as pinholes and cracks that are prone to occur in the weld seams, as mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water-cooled bearing housing welding device, comprising a feeding and transporting platform, a processing platform fixedly installed on one side of the feeding and transporting platform, and a slow-cooling transporting platform fixedly installed on the side of the processing platform away from the feeding and transporting platform. The feeding and transporting platform is fixedly installed on the ground, and the feeding and transporting platform, the processing platform, and the slow-cooling transporting platform are aligned with each other. An air duct is fixedly installed on the outer surface of the feeding and transporting platform, and a heating circulation mechanism is provided between the air duct and the feeding and transporting platform. The water-cooled bearing housing placed on the feeding and transporting platform and pre-welded can be heated by the heating circulation mechanism, so that the stress between the water-cooled bearing housing and the stainless steel plate can be removed during subsequent welding, reducing deformation and the generation of pinhole cracks, and improving the welding quality of the water-cooled bearing housing.

[0005] Preferably, the heating circulation mechanism includes an electric heating element, which is inserted into the interior of the air duct, and convection fans are fixedly installed on the outer surfaces of both sides of the air duct, and the convection fans are concentrically designed. The electric heating element is located outside the feeding and conveying platform, and the electric heating element is fixed to the air duct with screws.

[0006] By adopting the above technical solution, the air in the feeding and conveying platform can be circulated by the convection fan, and the air passing through the electric heating element can be heated by the activation of the electric heating element. The circulation of the air by the convection fan accelerates the preheating and heating of the air, reduces the energy consumed by heating, and heats the water-cooled bearing housing that moves through the feeding and conveying platform. This allows the stress generated by welding to be eliminated during subsequent welding processes, reduces the generation of pinholes and cracks, and improves the welding quality of the water-cooled bearing housing.

[0007] Preferably, a welding robot is fixedly installed on one side of the processing platform, a heat exchange plate is fixedly installed between the feeding and conveying platform and the air duct, and the heat exchange plate is connected to the air outlet of the welding torch of the welding robot and the air inlet of the welding robot.

[0008] By adopting the above technical solution, the welding efficiency can be improved by using a welding robot. The residual heat emitted from the air duct can be reused by heat exchange plates, and the gas used by the welding robot can be preheated by the heat exchange plates. This reduces the cooling rate of the weldment during welding, avoids the formation of hardened structures due to rapid cooling, reduces the possibility of defects such as pinholes and porosity in the weld, improves the strength and toughness of the weld, and makes the welding process smoother, reducing the number of interruptions and repairs. It also reduces the amount of smoke and spatter generated during welding, and reduces the generation of harmful gases and dust.

[0009] Preferably, an exhaust fan cover is fixedly installed between the feeding and transporting platform and the slow-cooling transporting platform, and the exhaust fan cover is located above the processing platform. The exhaust fan cover has an exhaust pipe connected to its air outlet. A support sliding mechanism is provided between the feeding and transporting platform and the slow-cooling transporting platform. The support sliding mechanism facilitates the movement and transport of the water-cooled bearing seat that needs to be heated and welded.

[0010] By adopting the above technical solution, the fumes and dust generated during welding can be extracted through the exhaust fan cover, so that the fumes and dust will not exist in the processing workshop, reducing the health hazards caused by workers inhaling the fumes and dust.

[0011] Preferably, the supporting sliding mechanism includes: a sliding rod, the two ends of which are respectively fixedly installed on the outer surfaces of the feeding conveyor platform and the slow cooling conveyor platform, and a linear motor assembly is fixedly installed between the slow cooling conveyor platform and the feeding conveyor platform, and the linear motor assembly is connected to the exhaust fan cover, the outer surface of the linear motor assembly is penetrated by the sliding rod, and the sliding rod and the linear motor assembly are slidably connected, and an electromagnetic adsorption platform is fixedly installed inside the processing platform.

[0012] By adopting the above technical solution, the stability of the linear motor assembly during movement can be improved by using the slide rod. The movement of the linear motor assembly on the slide rod can drive the telescopic gripper to move, making it convenient to pick up the water-cooled bearing seat to be welded and place it on the outer surface of the processing platform. The water-cooled bearing seat is fixed by the electromagnetic adsorption platform set inside the processing platform, so that the water-cooled bearing seat will not move due to the contact of the welding robot during the welding process.

[0013] Preferably, the outer surface of the feeding and transporting platform near the processing platform is provided with a sliding pushing mechanism. The sliding pushing mechanism is used to position the transported water-cooled bearing seat, so that the telescopic gripper can be more accurate when transporting and placing the water-cooled bearing seat on the outer surface of the processing platform.

[0014] By adopting the above technical solution, the water-cooled bearing housing can be blocked and initially positioned on the feeding and transport platform, allowing the subsequent telescopic gripper to move the water-cooled bearing housing to the processing platform more accurately, reducing the welding error rate of the welding robot, and enabling the welding robot to perform processing and welding faster.

[0015] Preferably, the sliding pushing mechanism includes: a telescopic cylinder, which is fixed to the outer surfaces of both sides of the feeding and conveying platform, and a positioning push rod is slidably installed on the outer surface of the feeding and conveying platform, and the positioning push rod is engaged with the feeding and conveying platform. The outer surface of the positioning push rod penetrates the outer surface of the output end of the telescopic cylinder, and the telescopic cylinder and the positioning push rod are slidably connected. The positioning push rod is engaged with the telescopic cylinder, and a fixing screw is threaded on the outer surface of the output end of the telescopic cylinder, and the outer surface of the fixing screw is in contact with the outer surface of the positioning push rod. A limit stop is fixedly installed on the outer surface of the feeding and conveying platform near the exhaust fan cover, and a contact switch is fixedly installed on the outer surface of the limit stop, and the outer surface of the contact switch is in contact with the outer surface of the water-cooled bearing seat.

[0016] Using the above technical solution, when the water-cooled bearing housing is welded and moved to the surface of the slow-cooling transport platform by the telescopic gripper, the feeding transport platform will move, causing the water-cooled bearing housing to move. This allows the water-cooled bearing housing to be blocked by the limit stop and trigger the contact switch, enabling the telescopic cylinder to move the positioning push rod. The water-cooled bearing housing will then be pushed to the center position of the limit stop. The position of the positioning push rod can be adjusted according to the fixed set screw, allowing water-cooled bearing housings of different sizes to be positioned.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the water-cooled bearing housing welding device:

[0018] 1. The convection fan can circulate the air in the feeding and conveying platform, and the electric heating element can heat and circulate the air, which can be preheated and heated more quickly and reduce the energy consumption of heating the air. The water-cooled bearing housing transported and moved by the feeding and conveying platform can be heated. Heating the water-cooled bearing housing reduces and eliminates the stress generated during subsequent welding, reduces the probability of cracks and pinholes, and improves the welding quality of the water-cooled bearing housing.

[0019] 2. By absorbing the residual heat emitted from the air duct through heat exchange fins, the heat emitted by the hot air can be recovered and reused. The welding gas used by the welding robot can be preheated through the heat exchange fins, which can reduce the smoke, dust and spatter generated by the weldment when the welding robot uses air later. It can also avoid the hardened structure formed by rapid cooling during welding, reduce the number of interruptions and repairs during welding, reduce the possibility of cracks and porosity during welding, and make the weld stronger and tougher, thus improving the quality of welding water-cooled bearing housing.

[0020] 3. By starting the linear motor assembly, the linear motor assembly can move along the direction of the slide rod, so that the telescopic gripper can extend and retract to grip and move the water-cooled bearing seat. The telescopic gripper can be moved to the top of the processing platform for placement, and the water-cooled bearing seat is attracted and fixed by the electromagnetic adsorption platform, so that the water-cooled bearing seat will not fail to weld due to movement during welding.

[0021] 4. After welding is completed, the telescopic gripper will pick up the water-cooled bearing housing and place it on the outer surface of the slow-cooling transport platform for slow cooling. At the same time, the feeding transport platform will move and drive the water-cooled bearing housing to move, so that the water-cooled bearing housing is in contact with the limit stop bar. The telescopic cylinder is activated by the contact switch to stop the feeding transport platform, so that the positioning push rod can push the water-cooled bearing housing to limit and position. The position of the positioning push rod can be adjusted by the fixing set screw, so that water-cooled bearing housings of different sizes can be positioned, and the welding robot can operate and weld faster during subsequent processing and welding.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a water-cooled bearing housing welding device, including a feeding and transporting platform 1, a processing platform 2 fixedly installed on one side of the feeding and transporting platform 1, and a slow-cooling transporting platform 3 fixedly installed on the side of the processing platform 2 away from the feeding and transporting platform 1. The feeding and transporting platform 1 is fixedly installed on the ground, and the feeding and transporting platform 1, the processing platform 2 and the slow-cooling transporting platform 3 are aligned with each other. An air duct 5 is fixedly installed on the outer surface of the feeding and transporting platform 1, and a heating circulation mechanism is provided between the air duct 5 and the feeding and transporting platform 1. The water-cooled bearing housing placed on the feeding and transporting platform 1 and pre-welded can be heated by the heating circulation mechanism, so that the stress between the water-cooled bearing housing and the stainless steel plate can be removed during subsequent welding, reducing deformation and the generation of sand hole cracks, and improving the quality of water-cooled bearing housing welding.

[0031] The material feeding platform 1, processing platform 2, and slow cooling transport platform 3 are aligned with each other, which makes the subsequent transportation and movement of water-cooled bearing housings more stable and accurate. At the same time, it is convenient to remove the electric heating element 7 from the air duct 5 for cleaning and maintenance, thereby improving the accuracy of welding water-cooled bearing housings and improving the welding quality and speed of water-cooled bearing housings.

[0032] The heating circulation mechanism includes an electric heating element 7, which is inserted into the air duct 5. Convection fans 6 are fixedly installed on the outer surfaces of both sides of the air duct 5, and the convection fans 6 are concentrically designed. The electric heating element 7 is located outside the feeding and conveying platform 1, and the electric heating element 7 is fixed to the air duct 5 with screws.

[0033] When using the equipment, the pre-welded water-cooled bearing housing and stainless steel plate should first be placed on the outer surface of the feeding and conveying platform 1. Then, the convection fan 6 and electric heating element 7 can be turned on, so that the air can circulate inside the feeding and conveying platform 1 through the convection fan 6 and be heated by the electric heating element 7, thereby increasing the preheating and heating speed and reducing the energy consumed during heating. The water-cooled bearing housing can be heated when it passes through the feeding and conveying platform 1. When the heated water-cooled bearing housing is placed on the processing platform 2 for welding, the stress deformation generated during welding can be reduced, thereby reducing the probability of cracks and pinholes and improving the quality of welding.

[0034] A welding robot 4 is fixedly installed on one side of the processing platform 2. A heat exchange plate 8 is fixedly installed between the feeding and transport platform 1 and the air duct 5. The heat exchange plate 8 is connected to the welding gun outlet of the welding robot 4 and the air inlet of the welding robot 4.

[0035] The welding robot 4 can improve welding efficiency. At the same time, the heat exchange plate 8 can absorb the heat emitted by the air duct 5 and the electric heating plate 7 to preheat the gas used by the welding robot 4. The welding robot 4 uses preheated gas to reduce the smoke, dust and spatter generated during welding. It can also avoid hardening of the structure caused by cold gas during welding, reduce the number of welding interruptions and repairs, and reduce the possibility of cracks and porosity during welding. This results in higher weld strength and toughness, thereby improving the welding quality of the water-cooled bearing housing.

[0036] An exhaust fan cover 9 is fixedly installed between the feeding and transporting platform 1 and the slow cooling transporting platform 3. The exhaust fan cover 9 is located above the processing platform 2. The exhaust fan cover 9 is connected to an exhaust pipe at its air outlet. A support sliding mechanism is provided between the feeding and transporting platform 1 and the slow cooling transporting platform 3. The support sliding mechanism facilitates the movement and transport of the water-cooled bearing seat that needs to be heated and welded.

[0037] Dust and fumes are inevitably generated during the welding of water-cooled bearing housings. At this time, the dust and fumes can be collected and discharged outward by the rotation and collection of the exhaust fan cover 9, so that the dust and fumes will not remain in the processing workshop and reduce the harm caused by workers inhaling dust and fumes.

[0038] The supporting sliding mechanism includes: a slide rod 11, with both ends of the slide rod 11 fixedly installed on the outer surfaces of the feeding and conveying platform 1 and the slow cooling conveying platform 3, respectively. A linear motor assembly 12 is fixedly installed between the slow cooling conveying platform 3 and the feeding and conveying platform 1, and the linear motor assembly 12 is connected to the exhaust fan cover 9. The outer surface of the linear motor assembly 12 is penetrated by the slide rod 11, and the slide rod 11 and the linear motor assembly 12 are slidably connected. An electromagnetic adsorption platform 10 is fixedly installed inside the processing platform 2.

[0039] The linear motor assembly 12 can be improved in terms of load-bearing capacity during movement by means of the slide rod 11. The telescopic gripper 13 can move along the direction of the slide rod 11 by means of the linear motor assembly 12, so that the telescopic gripper 13 can pick up the heated water-cooled bearing seat and place it on the outer surface of the processing platform 2. At the same time, the electromagnetic adsorption platform 10 is activated to adsorb the placed water-cooled bearing seat, which facilitates the handling, movement and fixation of the water-cooled bearing seat, so that the water-cooled bearing seat will not move during welding, thereby improving the speed and quality of welding the water-cooled bearing seat.

[0040] A sliding pushing mechanism is provided on the outer surface of the feeding and transporting platform 1 near the processing platform 2. The sliding pushing mechanism is used to position the transported water-cooled bearing seat, so that the telescopic gripper 13 can be more accurate when transporting and placing the water-cooled bearing seat on the outer surface of the processing platform 2.

[0041] After the feeding and conveying platform 1 moves the water-cooled bearing housing and is blocked by the limit stop bar 14, the contact switch 15 will be triggered, causing the feeding and conveying platform 1 and the slow cooling conveying platform 3 to stop. The telescopic cylinder 16 starts and drives the positioning push rod 17 to move, so that the positioning push rod 17 can push the water-cooled bearing housing to move and position. This allows the water-cooled bearing housing to be placed in the designated position when it is transported and moved by the telescopic gripper 13, thereby improving the efficiency of welding robot 4 in processing and welding.

[0042] The sliding and pushing mechanism includes: a telescopic cylinder 16, which is fixed on the outer surfaces of both sides of the feeding and conveying platform 1. A positioning push rod 17 is slidably installed on the outer surface of the feeding and conveying platform 1, and the positioning push rod 17 is engaged with the feeding and conveying platform 1. The outer surface of the positioning push rod 17 penetrates the outer surface of the output end of the telescopic cylinder 16, and the telescopic cylinder 16 and the positioning push rod 17 are slidably connected. The positioning push rod 17 is engaged with the telescopic cylinder 16, and a fixing screw 18 is threaded on the outer surface of the output end of the telescopic cylinder 16. The outer surface of the fixing screw 18 is in contact with the outer surface of the positioning push rod 17. A limit stop bar 14 is fixedly installed on the outer surface of the feeding and conveying platform 1 near the exhaust fan cover 9, and a contact switch 15 is fixedly installed on the outer surface of the limit stop bar 14. The outer surface of the contact switch 15 is in contact with the outer surface of the water-cooled bearing seat.

[0043] When welding a water-cooled bearing housing of another size, it is only necessary to adjust the position of the positioning push rod 17 by fixing the set screw 18, so that the distance between the positioning push rods 17 can be adjusted to position the water-cooled bearing housing of different sizes.

[0044] After welding is completed, the telescopic gripper 13 moves and clamps the water-cooled bearing housing, placing it on the outer surface of the slow-cooling transport platform 3. At the same time, the feeding transport platform 1 will restart and transport the new heated water-cooled bearing housing out of the air duct 5 and position it. Meanwhile, the telescopic gripper 13 will reset during the positioning process, so that after the water-cooled bearing housing is positioned, the telescopic gripper 13 will clamp the water-cooled bearing housing and perform welding again. This ensures that the other water-cooled bearing housing will not be moved out of the air duct 5 and cooled down during welding, thus ensuring the rationality of operation and improving the welding quality of the water-cooled bearing housing.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
