Description

Technical Field

[0001] The invention belongs to the technical field of aluminum alloy welding processing, and in particular relates to a welding device used for aluminum alloy processing. Background Art

[0002] Aluminum alloy has high thermal conductivity and specific heat capacity, which means that during the welding process, heat will be conducted away quickly, so the heating speed will also be faster. When welding, the welding position will be melted after heating, and pressure will be applied to make it bonded together again. Depending on the usage scenario, there are many choices of welding methods.

[0003] Chinese patent CN118287783B discloses an aluminum welding device, including a main body component, including a welding table, a welding tool, a wire feeding pen and a wire guide tube, the welding tool is arranged on the welding table, the wire feeding pen is located on the welding tool, and the wire guide tube is located in the wire feeding pen; and an adjustment component is arranged on the welding table, including a support member, a welding wire reel, a clamping member, a conveying member, a driving member, a positioning member, a pushing member and an isolating member, the support member is arranged on one side of the welding table, the welding wire reel is located in the support member, and the clamping member is located on one side of the welding table. The invention has the following beneficial effects: by arranging the adjustment component, the welding wire can be automatically replaced when it is used up, and the equipment does not need to be shut down, which can greatly reduce the downtime during welding, thereby significantly improving production efficiency.

[0004] Existing aluminum materials, especially those used for building frame profiles or equipment rack processing, are limited in welding length and shape when being welded. Conventional welding guns are prone to unstable welding parts when welding thicker solid parts. When hollow parts are clamped, the clamping position is easily deformed due to excessive clamping force. When too much pressure is applied, the flash at the welding position will be too large, making it difficult to handle later.

[0005] It is difficult to avoid the above problems at the same time during the existing aluminum alloy processing and welding. Therefore, we propose a welding device for aluminum alloy processing that can select different welding methods as needed, reduce structural deformation or excessive flash caused by excessive clamping force or pressure, and can quickly process the processed end surface. Summary of the invention

[0006] The purpose of the present invention is to target an existing welding device for aluminum alloy processing, which has the advantage that different welding methods can be selected as needed for welding, and the deformation of the structure or excessive burrs caused by excessive clamping force or pressure can be reduced, and the processed end face can be quickly processed.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: comprising a main welding platform and an auxiliary welding platform, the main welding platform is fixedly connected to the right side of the auxiliary welding platform, the top of the auxiliary welding platform is fixedly connected to a first electric cylinder, the telescopic end of the first electric cylinder is bolted to a tilting frame, the side of the tilting frame away from the first electric cylinder is fixedly connected to an airbag, the inner side of the main welding platform is rotatably connected to an auxiliary component, the inner side of the auxiliary welding platform is installed with a horizontal frame, and the inner side of the horizontal frame is slidably connected to a slide frame;

[0008] The auxiliary component includes an arc-shaped frame, a high-frequency power supply and an induction coil are fixedly connected to the top of the inner side of the arc-shaped frame, a cooling structure is provided on the inner side of the arc-shaped frame, a door frame is fixedly connected to the inner side of the arc-shaped frame, and a cleaning component is installed on the inner side of the door frame;

[0009] An axle box is provided on the right side of the main welding platform, a chuck is installed on the left side of the inner side of the axle box, a claw is installed on the inner side of the chuck, a reducer, a coupling and a motor are externally connected to the right side of the axle box, and an end pressure structure is installed on the inner side of the chuck.

[0010] The above technical scheme is adopted, by setting a main welding platform to cooperate with the auxiliary welding platform, and the inner side of the auxiliary component position of the main welding platform is used as the welding position. When performing welding operations, the auxiliary welding part is placed on the slide of the main welding platform, and the main welding part is placed on the top of the main welding platform. The horizontal position of the axle box is adjusted according to the length of the main welding part, so that the distance between the chuck and the welding position is close to the main welding part and the length, and the main welding part is placed on the inner side of the chuck, and the right side is pressed against the left side of the end pressure structure for limiting, and fixed by the claws. When performing welding operations, the arc frame of the auxiliary component is first rotated so that the cleaning component is located between the main welding part and the auxiliary welding part, and the welding surface is polished with sandpaper by the cleaning component to remove rust and impurities on the surface, and at the same time make its surface relatively rough, which is conducive to welding, and then the auxiliary component is rotated so that the induction coil is located outside the welding position, and then the airbag is filled with gas, and the first electric cylinder pushes the airbag close to the auxiliary welding part through the tilting frame, and the airbag tightly presses the auxiliary welding part and fits it. Its shape avoids structural deformation caused by excessive clamping force. Because the first electric cylinder and the tilting frame are tilted, the auxiliary weldment and the slide in contact with it can be pushed to slide along the horizontal frame, so that the welding surfaces of the auxiliary weldment and the main weldment are in contact. The high-frequency power supply energizes the induction coil to generate an alternating magnetic field and heats the welding position for induction welding. When the welding surfaces are in contact with each other, it will be difficult to push the auxiliary weldment and the main weldment against each other due to the continuous force of the airbag, but deformation and slippage will occur, which can reduce the generation of flash. When welding provides pressure, the main weldment will reduce the amount of displacement due to the limitation of the end pressure structure. When it is difficult to heat a thicker workpiece by induction, the external motor and reducer drive the chuck to rotate along the axle box, which will drive the main weldment clamped by the claws to rotate, and friction welding will be performed between the main weldment and the auxiliary weldment while continuously applying pressure. According to different weldment sizes and weldment types, the processing length and welding method of the structure can be flexibly adjusted to make the operation more flexible.

[0011] The present invention is further configured as follows: the cooling structure includes a water pump, a water tank and a heat exchanger, the output end of the water pump is fixedly connected to a cooling pipe, the cooling pipe, the water pump, the water tank and the heat exchanger are communicated, a fan frame fixedly connected to the arc-shaped frame is provided between the water pump and the cooling pipe, and a cooling fan is installed on the inner side of the fan frame.

[0012] By adopting the above technical scheme, a water pump is provided in combination with a cooling pipe, so that the circulation of the coolant can be facilitated. When the low-temperature coolant is inside the cooling pipe, the cooling fan inside the fan frame blows out airflow outward, and cools the airflow when it contacts the cooling pipe with the low-temperature coolant inside, and the welding position is air-cooled. Rapid air cooling after welding can not only accelerate the cooling of the welding position, but also eliminate stress to a certain extent. The coolant is stored inside the water tank, and the coolant is cooled by the heat exchanger, so that the coolant can be circulated and cooled.

[0013] The present invention is further configured as follows: the cleaning component includes an adjustment frame, a side frame is fixedly connected to the right side of the adjustment frame, a second electric cylinder is fixedly connected to the right side of the side frame, a rotating frame is rotatably connected to the inner side of the adjustment frame, a control motor is fixedly connected to the inner side of the rotating frame, a friction wheel is fixedly connected to the output end of the control motor, sandpaper is provided on the outer side of the friction wheel, and the telescopic end of the second electric cylinder is movably connected to the control motor.

[0014] The above technical solution is adopted, by setting an adjustment frame and a side frame to drive the control motor and the friction wheel. When the friction wheel rotates, it will grind the welding surface in contact with it. The sandpaper on the surface can not only grind impurities and rust on the welding surface, but also improve its surface roughness, which is convenient for welding. When the welding surface is difficult to touch, the control motor can be pushed or pulled by the second electric cylinder to adjust the angle of the friction wheel.

[0015] The present invention is further configured as follows: the end pressure structure includes a pressure box, a buffer shell is bolted on the inner side of the pressure box, a pressure plate is slidably connected to the inner side of the buffer shell, a spring is fixedly connected to the right side of the pressure plate, the right side of the spring is fixedly connected to the pressure box, a cross bar is fixedly connected to the left side of the pressure plate, and a contact plate is fixedly connected to the left side of the cross bar.

[0016] By adopting the above technical solution, a pressure box is set up to limit the main weldment when it contacts the contact piece. When the main weldment is pressed, the contact piece and the cross bar in contact with it will move along the inner side of the buffer shell, and push the internal fluid medium to flow through the inner opening of the buffer shell to achieve a buffering effect. At this time, the spring is deformed, and after the welding is completed or the pressure is stopped, the spring rebounds and resets. The displacement provided to the main weldment can reduce the generation of flash by reducing the relative pressure between the main weldment and the auxiliary weldment.

[0017] The present invention is further configured as follows: a short shaft is fixedly connected to the inner side of the main welding platform, a connecting frame is rotatably connected to the outer side of the short shaft, and a side of the connecting frame close to the arc frame is fixedly connected to the arc frame.

[0018] By adopting the above technical solution, by providing a short shaft and a connecting frame, the main welding platform and the arc frame can be easily connected, and the arc frame can be rotated along the main welding platform.

[0019] The present invention is further configured as follows: a groove matching the arc frame is opened on the inner side of the main welding platform, and spring plates are fixedly connected to the outer side of the arc frame and the inner side of the groove, and the spring plate on the left side is movably connected to the spring plate on the right side.

[0020] By adopting the above technical solution, the movement of the arc-shaped frame can be limited by providing the spring piece, and the provided groove can facilitate the movement of the arc-shaped frame.

[0021] The present invention is further configured as follows: a guide frame is fixedly connected to the right side of the control motor, a guide block is slidably connected to the inner side of the guide frame, and the telescopic end of the second electric cylinder is rotatably connected to the guide block.

[0022] By adopting the above technical solution, by setting a guide frame in combination with a guide block, when the control motor is dragged or pushed by the second electric cylinder, the guide block can slide inside the guide frame to apply reasonable push and pull force to avoid structural jamming.

[0023] The present invention is further configured as follows: a cylinder is fixedly connected to the bottom of the slide, and a telescopic end of the cylinder penetrates the slide and is fixedly connected to a lifting plate.

[0024] By adopting the above technical solution, by setting up a cylinder in conjunction with a lifting plate, it is possible to assist in lifting or lowering the auxiliary weldment, and at the same time, the entire workpiece can be lifted after welding to facilitate loading and unloading.

[0025] The present invention is further configured as follows: a strap and a buckle are installed on the top of the auxiliary welding platform, and the strap and the buckle are movably connected.

[0026] By adopting the above technical solution, by setting a strap and a buckle, when the weldment is too long or irregular, the strap can be passed through the buckle to fix the auxiliary weldment on the top of the auxiliary welding platform, thereby limiting the workpiece.

[0027] The present invention is further configured as follows: a guide rail is fixedly connected to the bottom of the main welding platform, a screw rod is rotatably connected to the inner side of the guide rail, a transmission block is threadedly connected to the outer side of the screw rod, the top of the transmission block is fixedly connected to the axle box, and the outer side of the transmission block is slidably connected to the guide rail.

[0028] By adopting the above technical solution, by setting a guide rail and a screw rod, when the screw rod rotates, the transmission block will rotate along the guide rail to drive the axle box to move horizontally.

[0029] In summary, the present invention has the following beneficial effects:

[0030] By setting up a main welding platform to match the auxiliary welding platform, the structure of the weldment and the device is fixed and supported. According to the length of the main weldment, the horizontal position of the axle box can be matched with the length of the main weldment, and the main weldment is placed on the inner side of the chuck to fix the main weldment. When welding, the arc frame of the auxiliary component can be rotated first, so that the cleaning component is located between the main weldment and the auxiliary weldment, and the welding surface is polished with sandpaper by the cleaning component to remove the rust and impurities on the surface, and at the same time make the surface relatively rough, which is conducive to welding. After the induction coil of the auxiliary component is located in the welding position, induction welding can be performed. After the airbag is filled with gas, it cooperates with the first electric cylinder. The auxiliary weldment that can be fastened by the airbag is pushed and fixed by the tilting frame. When the welding surfaces are in contact with each other, it will be difficult to push the auxiliary weldment against the main weldment due to the continuous force of the airbag, and deformation and slipping will occur. Because the pressure is reduced, the flash will be reduced. When it is difficult to heat the thicker workpiece by induction, the external motor and reducer drive the chuck to rotate along the axle box, which will drive the main weldment clamped by the claws to rotate, and friction welding will be performed between the main weldment and the auxiliary weldment while continuously applying pressure. According to different weldment sizes and weldment types, the processing length and welding method of the structure can be flexibly adjusted to make the operation more flexible.

[0040] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0041] Embodiment 1:

[0042] refer to Figure 1-Figure 6 A welding device for aluminum alloy processing, comprising a main welding platform 1 and an auxiliary welding platform 2, wherein the main welding platform 1 is fixedly connected to the right side of the auxiliary welding platform 2, a first electric cylinder 3 is fixedly connected to the top of the auxiliary welding platform 2, a tilting frame 4 is bolted to the telescopic end of the first electric cylinder 3, an air bag 5 is fixedly connected to the side of the tilting frame 4 away from the first electric cylinder 3, an auxiliary component 6 is rotatably connected to the inner side of the main welding platform 1, a horizontal frame 11 is installed on the inner side of the auxiliary welding platform 2, and a slide 12 is slidably connected to the inner side of the horizontal frame 11;

[0043] The auxiliary component 6 includes an arc-shaped frame 601, a high-frequency power supply 602 and an induction coil 603 are fixedly connected to the top of the inner side of the arc-shaped frame 601, a cooling structure 604 is provided on the inner side of the arc-shaped frame 601, a door frame 605 is fixedly connected to the inner side of the arc-shaped frame 601, and a cleaning component 606 is installed on the inner side of the door frame 605;

[0044] By setting the main welding platform 1 to cooperate with the auxiliary welding platform 2, the inner side of the auxiliary component 6 of the main welding platform 1 is used as the welding position. When performing welding operations, the auxiliary welding piece is placed on the slide 12 of the main welding platform 1, and the main welding piece is placed on the top of the main welding platform 1. The horizontal position of the axle box 7 is adjusted according to the length of the main welding piece, so that the distance between the chuck 8 and the welding position is close to the length of the main welding piece, and the main welding piece is placed on the inner side of the chuck 8, and the right side is pressed against the left side of the end pressure structure 9 for limiting, and fixed by the claw 10. When performing welding operations, first rotate the arc frame 601 of the auxiliary component 6 so that the cleaning component 606 is located between the main welding piece and the auxiliary welding piece, and the welding surface is sanded by the cleaning component 606. After grinding, the rust and impurities on the surface are removed and the surface becomes relatively rough, which is conducive to welding. The auxiliary component 6 is then rotated to make the induction coil 603 located outside the welding position. The airbag 5 is then filled with gas. The first electric cylinder 3 pushes the airbag 5 close to the auxiliary weldment through the tilting frame 4. The airbag 5 tightly presses the auxiliary weldment and fits its shape to avoid structural deformation caused by excessive clamping force. Because the first electric cylinder 3 and the tilting frame 4 are tilted, the auxiliary weldment and the slide 12 in contact with it can be pushed to slide along the horizontal frame 11, so that the welding surfaces of the auxiliary weldment and the main weldment are in contact. The high-frequency power supply 602 energizes the induction coil 603 to generate an alternating magnetic field and heats the welding position for induction welding.

[0045] like Figure 5 As shown, the cooling structure 604 includes a water pump 604a, a water tank 604b and a heat exchanger 604c. The output end of the water pump 604a is fixedly connected to a cooling pipe 604d. The cooling pipe 604d, the water pump 604a, the water tank 604b and the heat exchanger 604c are connected. A fan frame 604e fixedly connected to the arc frame 601 is provided between the water pump 604a and the cooling pipe 604d. A heat dissipation fan is installed inside the fan frame 604e. By arranging the water pump 604a in conjunction with the cooling pipe 604d, it is convenient to provide cooling. The cooling liquid circulates, and when the low-temperature cooling liquid is inside the cooling pipe 604d, the cooling fan inside the fan frame 604e blows out airflow outward, and cools the airflow when it contacts the cooling pipe 604d with the low-temperature cooling liquid inside, and air-cools the welding position. Rapid air cooling after welding can not only accelerate the cooling of the welding position, but also eliminate stress to a certain extent. The cooling liquid is stored in the water tank 604b, and the cooling liquid is cooled by the heat exchanger 604c, which can facilitate the circulation and cooling of the cooling liquid.

[0046] like Figure 6As shown, the cleaning assembly 606 includes an adjustment frame 606a, a side frame 606b is fixedly connected to the right side of the adjustment frame 606a, a second electric cylinder 606c is fixedly connected to the right side of the side frame 606b, a rotating frame 606d is rotatably connected to the inner side of the adjustment frame 606a, a control motor 606e is fixedly connected to the inner side of the rotating frame 606d, a friction wheel 606f is fixedly connected to the output end of the control motor 606e, and sandpaper is provided on the outer side of the friction wheel 606f. The telescopic end of the second electric cylinder 606c and the control motor 606 e is movably connected, and an adjustment frame 606a is provided to cooperate with a side frame 606b to drive a control motor 606e and a friction wheel 606f. When the friction wheel 606f rotates, it will grind the welding surface in contact with it. The sandpaper on the surface can improve the surface roughness while grinding impurities and rust on the welding surface, so as to facilitate welding. When the welding surface is difficult to touch, the control motor 606e can be pushed or pulled by the second electric cylinder 606c to adjust the angle of the friction wheel 606f.

[0047] like Figure 5 As shown, a short shaft 13 is fixedly connected to the inner side of the main welding platform 1, and a connecting frame 14 is rotatably connected to the outer side of the short shaft 13. The connecting frame 14 is fixedly connected to the arc frame 601 on one side close to the arc frame 601. By arranging the short shaft 13 in conjunction with the connecting frame 14, the main welding platform 1 and the arc frame 601 can be easily connected, and the arc frame 601 can be rotated along the main welding platform 1.

[0048] like Figure 1 As shown, a groove cooperating with the arc-shaped frame 601 is provided on the inner side of the main welding platform 1, and spring pieces 15 are fixedly connected to the outer side of the arc-shaped frame 601 and the inner side of the groove. The spring piece 15 on the left side and the spring piece 15 on the right side are movably connected. By setting the spring piece 15, the movement of the arc-shaped frame 601 can be limited, and the groove can facilitate the movement of the arc-shaped frame 601.

[0049] like Figure 6 As shown, the right side of the control motor 606e is fixedly connected to a guide frame 16, the inner side of the guide frame 16 is slidably connected to a guide block 17, and the telescopic end of the second electric cylinder 606c is rotatably connected to the guide block 17. By arranging the guide frame 16 to cooperate with the guide block 17, when the control motor 606e is dragged or pushed by the second electric cylinder 606c, reasonable push and pull force can be applied through the sliding of the guide block 17 inside the guide frame 16, thereby avoiding jamming of the structure.

[0050] like Figure 3As shown, a cylinder 18 is fixedly connected to the bottom of the slide 12, and the telescopic end of the cylinder 18 passes through the slide 12 and is fixedly connected to a lifting plate 19. By arranging the cylinder 18 in conjunction with the lifting plate 19, it is convenient to assist in lifting or lowering the auxiliary weldment, and at the same time, the entire workpiece can be lifted after welding is completed to facilitate loading and unloading.

[0051] like Figure 1 As shown, a strap 20 and a buckle 21 are installed on the top of the auxiliary welding platform 2, and the strap 20 and the buckle 21 are movably connected. By arranging the strap 20 to cooperate with the buckle 21, when the weldment is too long or irregular, the strap 20 can be passed through the buckle 21 to fix the auxiliary weldment on the top of the auxiliary welding platform 2, thereby achieving the effect of limiting the workpiece.

[0052] Brief description of the use process: First, place the auxiliary welding part on the slide 12 of the main welding platform 1, and place the main welding part on the top of the main welding platform 1, adjust the horizontal position of the axle box 7 according to the length of the main welding part, make the distance between the chuck 8 and the welding position close to the main welding part and the length, and place the main welding part on the inner side of the chuck 8, and press the right side against the left side of the end pressure structure 9 for limiting, and fix it with the claw 10. When the welding surface is too smooth or there are many impurities, rotate the arc frame 601 of the auxiliary component 6 so that the cleaning component 606 is located between the main welding part and the auxiliary welding part, and use the cleaning component 606 to grind the welding surface with sandpaper to remove the rust on its surface. And impurities are ground off, and its surface becomes relatively rough. After rotating the auxiliary component 6, the induction coil 603 is located outside the welding position, and then the airbag 5 is filled with gas. The first electric cylinder 3 pushes the airbag 5 close to the auxiliary weldment through the tilting frame 4. The airbag 5 tightly presses the auxiliary weldment and fits its shape to avoid structural deformation caused by excessive clamping force. Because the first electric cylinder 3 and the tilting frame 4 are inclined, the auxiliary weldment and the slide 12 in contact with it can be pushed to slide along the horizontal frame 11, so that the welding surfaces of the auxiliary weldment and the main weldment are in contact. The high-frequency power supply 602 energizes the induction coil 603 to generate an alternating magnetic field and heats the welding position for induction welding.

[0053] Embodiment 2:

[0054] refer to Figure 1-Figure 8 A welding device for aluminum alloy processing, comprising a main welding platform 1 and an auxiliary welding platform 2, wherein the main welding platform 1 is fixedly connected to the right side of the auxiliary welding platform 2, a first electric cylinder 3 is fixedly connected to the top of the auxiliary welding platform 2, a tilting frame 4 is bolted to the telescopic end of the first electric cylinder 3, an air bag 5 is fixedly connected to the side of the tilting frame 4 away from the first electric cylinder 3, an auxiliary component 6 is rotatably connected to the inner side of the main welding platform 1, a horizontal frame 11 is installed on the inner side of the auxiliary welding platform 2, and a slide 12 is slidably connected to the inner side of the horizontal frame 11;

[0055] An axle box 7 is provided on the right side of the main welding platform 1, a chuck 8 is installed on the left side of the inner side of the axle box 7, a claw 10 is installed on the inner side of the chuck 8, a reducer, a coupling and a motor are externally connected to the right side of the axle box 7, and an end pressure structure 9 is installed on the inner side of the chuck 8;

[0056] When the welding surfaces are in contact with each other, it will be difficult to push the auxiliary weldment and the main weldment against each other if the airbag 5 continues to apply force. Instead, it will deform and slip, which can reduce the generation of flash. When the welding provides pressure, the main weldment will reduce the amount of displacement due to the limitation of the end pressure structure 9. When it is difficult to heat the thicker workpiece by induction, the external motor and reducer drive the chuck 8 to rotate along the axle box 7, which will drive the main weldment clamped by the claws 10 to rotate, and friction welding will be performed between the main weldment and the auxiliary weldment while continuously applying pressure. According to different weldment sizes and weldment types, the processing length and welding method of the structure can be flexibly adjusted to make the operation more flexible.

[0057] like Figure 7 As shown, the end pressure structure 9 includes a pressure box 901, a buffer shell 902 is bolted to the inner side of the pressure box 901, a pressure piece 903 is slidably connected to the inner side of the buffer shell 902, a spring 904 is fixedly connected to the right side of the pressure piece 903, the right side of the spring 904 is fixedly connected to the pressure box 901, a cross bar 905 is fixedly connected to the left side of the pressure piece 903, and a contact piece 906 is fixedly connected to the left side of the cross bar 905. By setting the pressure box 901, when the main weldment contacts the contact piece 906, the main weldment will be The parts are limited, and when the main weldment is subjected to force and pressure, the contact piece 906 and the cross bar 905 in contact with it will move along the inner side of the buffer shell 902, and push the internal fluid medium to flow through the inner opening of the buffer shell 902 to achieve a buffering effect. At this time, the spring 904 is deformed, and when the welding is completed or the pressure is stopped, the spring 904 rebounds and resets. The displacement amount provided to the main weldment can reduce the generation of flash by reducing the relative pressure between the main weldment and the auxiliary weldment.

[0058] like Figure 1 As shown, the bottom of the main welding platform 1 is fixedly connected to a guide rail 22, the inner side of the guide rail 22 is rotatably connected to a screw rod 23, the outer side of the screw rod 23 is threadedly connected to a transmission block 24, the top of the transmission block 24 is fixedly connected to the axle box 7, and the outer side of the transmission block 24 is slidably connected to the guide rail 22. By arranging the guide rail 22 to cooperate with the screw rod 23, when the screw rod 23 rotates, the transmission block 24 will rotate along the guide rail 22 to drive the axle box 7 to move horizontally.

[0059] Brief description of the usage process: When welding, it will be difficult to push the auxiliary weldment against the main weldment if the airbag 5 continues to apply force, but it will deform and slip, which can reduce the generation of flash. When welding provides pressure, the contact piece 906 and the cross bar 905 in contact with it will move along the inner side of the buffer shell 902, and push the internal fluid medium to flow through the inner opening of the buffer shell 902 to achieve a buffering effect. At this time, the spring 904 is deformed. After the welding is completed or the pressure is stopped, the spring 904 rebounds and resets. The displacement provided to the main weldment can reduce the generation of flash by reducing the relative pressure between the main weldment and the auxiliary weldment. When it is difficult to heat a thicker workpiece by induction, the external motor and reducer drive the chuck 8 to rotate along the axle box 7, which will drive the main weldment clamped by the claws 10 to rotate, and friction welding is performed between the main weldment and the auxiliary weldment while continuously applying pressure.
