Description

Technical Field

[0001] The invention relates to the technical field of blade seam welding fixtures, and in particular to a blade seam welding fixture and a clamping method thereof. Background Art

[0002] Blade seam welding is a welding process required during the processing and production of blades. The main principle is to make the workpiece pass between two rotating disc electrodes (rollers) to form a continuous weld with overlapping welds. The disc-shaped electrode replaces the cylindrical electrode for spot welding and moves relative to the workpiece. During this process, corresponding fixtures are used to stabilize and limit its position.

[0003] When traditional blades and blade rings are seam-welded, the clamp used generally extends the limit head of the clamp into the inner wall of the inner ring located at the center of the blade, and then the limit head is stretched to fix the position of the blade. Then, during the seam welding process, the axis of the limit head of the clamp rotates, thereby seam-welding the blade ring on the outer ring of the blade. However, it was found in actual use that because there was a certain gap between the blade and the blade ring before processing, there was a certain relative shaking between the blade and the blade ring during the rotation of the workpiece, which affected the normal progress of the seam welding and reduced the quality and effect of the seam welding. There would be some defective gaps, which affected the normal use of the blade in the later stage and reduced the normal progress and work efficiency of the seam welding operation.

[0006] The effect achieved by the above-mentioned components is: when the blade is seam welded, the reinforcement device is first installed on the workbench with the help of the connecting device, and then the inner ring of the blade is placed on the fixed head at one end of the clamping rod frame, and then the fixed head is started to open the fixed head to fix the blade, and then the reinforcement device is started to make the reinforcement device just contact the limit of the blade ring of the outer ring of the blade, and then the machine is started to rotate the clamping rod frame, so that the workpiece is rotated, and the corresponding weld position is seam welded.

[0007] Preferably, the reinforcement device includes a slide rail, which is installed on the surface of the workbench by means of a connecting device, the inner wall of the slide rail is fixedly connected with a mounting plate, both sides of the surface of the mounting plate are respectively fixedly connected with springs, the other end of the spring is fixedly connected with an assembly plate, the assembly plate is slidably connected to the inner wall of the slide rail, one side surface of the assembly plate is fixedly connected with a stabilizing plate, the cross-section of the stabilizing plate is "U"-shaped, both ends of the stabilizing plate are rotatably connected with a rotating shaft, and a roller is rotatably connected to the circular arc surface of the rotating shaft, one side surface of the assembly plate is fixedly connected with a mounting rod, the circular arc surface of the mounting rod is fixedly connected with a connecting belt, the other end of the connecting belt is fixedly connected with a rotating rod, one end of the rotating rod is rotatably connected to the surface of the slide rail, the circular arc surface of the rotating rod is fixedly connected with a first gear, one side surface of the slide rail is fixedly connected with a servo motor, the output end of the servo motor is fixedly connected with a second gear, and the first gear is meshed with the second gear.

[0008] The effect achieved by the above components is: when the blade is seam-welded, the reinforcement device is first installed on the workbench with the help of the connecting device, and then the inner ring of the blade is placed on the fixed head at one end of the clamping rod frame, and then the fixed head is operated and started to open the fixed head to fix the blade, and then the servo motor on the slide rail is started. Because the first gear is meshed with the second gear, the rotation of the output end of the servo motor will drive the rotation of the first gear, thereby causing the rotating rod on one side of the slide rail to rotate. At this time, the two connecting belts on the rotating rod are wrapped around the rotating rod, and at this time, the assembly plate connected to the mounting rod at one end of the connecting belt will Sliding on the inner wall of the slide rail drives the stabilizing plate on the assembly plate to approach the workpiece until the roller on the arc surface of the rotating shaft on the assembly plate just contacts the leaf ring on the blade.

[0010] The effect achieved by the above-mentioned components is: through the setting of the brush plate, when the blade rotates and drives the leaf ring to rotate at the same time, the roller will rotate due to the contact with the leaf ring, thereby contacting the surface of the brush plate, and cleaning off the welding slag adhered to the surface of the leaf ring, facilitating subsequent normal seam welding processing, and improving the use effect and functionality of the reinforcement device.

[0011] Preferably, the surface of the slide rail is fixedly connected to mounting frames at both sides of the rotating rod, and the inner wall of the mounting frame is clamped with a protective plate, and the protective plate cover is arranged on the surface of the first gear.

[0012] The effect achieved by the above components is: through the setting of the protective plate and the mounting frame, the welding slag generated by the blade during the seam welding process is not easy to fall on the surface of the first gear and the second gear when it falls, so that the two can be guaranteed to be normal when they are engaged and rotated with each other and are not easily stuck by the welding slag, thereby ensuring the normal operation of the reinforcement device and better using the servo motor to drive the device components.

[0014] The effect achieved by the above components is: through the setting of the sliding rod and the limit plate, the assembly plate can be more stable when moving on the inner wall of the slide rail, and it is not easy to have abnormal shaking. The stability of the roller position is also guaranteed, so that the roller on the rotating shaft can be more stably adapted to the surface of the blade ring on the outer ring of the blade, thereby improving the limiting use effect of the reinforcement device.

[0015] Preferably, a wire take-up drum is fixedly connected to the arc surface of the rotating rod, and the connecting belt is wound around the arc surface of the inner wall of the wire take-up drum.

[0016] The effect achieved by the above components is: through the setting of the take-up reel, the position of the connecting belt can be more stable and concentrated when it is wound on the rotating rod, and it is not easy for the connecting belt to be offset from the rotating rod during winding, thereby ensuring the stable movement of the two assembly plates and maintaining the normal function of the reinforcement device.

[0017] Preferably, the connecting device includes two fixing rods, the two fixing rods are fixedly connected to one side surface of the slide rail, the surface of the workbench is fixedly connected to two fixing frames, the two fixing rods are respectively plugged into the inner walls of the two fixing frames, the surface of the workbench is fixedly connected to a mounting block, the surface of the mounting block is rotatably connected with a screw, both ends of the screw are respectively provided with threaded connections in opposite directions, both ends of the screw are respectively threadedly connected with clamping plates, the side surfaces of the two fixing rods close to each other are respectively provided with clamping grooves, the clamping plates are clamped with the inner walls of the clamping grooves, one side surface of the mounting block is fixedly connected to a limiting rod, and the limiting rod is slidably connected to the surface of the clamping plate.

[0018] The effect achieved by the above components is: when using the connecting device to fix the reinforcement device, first insert the two fixing rods on the surface of the slide rail into the two fixing frames on the surface of the workbench respectively, and then rotate the screw on the mounting block. Because the limit rod on the mounting block limits the sliding direction of the card plate, the card plates on both sides of the screw will move away from each other until the two card plates are respectively engaged with the card grooves on the two fixing rods. At this time, the reinforcement device is more convenient to assemble when in use, and then the blade seam welding can be limited and stabilized more efficiently, which improves the convenience of use of the reinforcement device, and also facilitates the daily disassembly and assembly of the reinforcement device, which is convenient for the staff to inspect and maintain it, and ensures the normal use of the reinforcement device.

[0019] Preferably, nuts are threadedly connected on the arc surfaces at both ends of the screw, and the nuts abut against the surface of the clamping plate. Reinforcement plates are fixedly connected to the one side surfaces of the two fixed frames, and rotating holes are opened on the surfaces of the reinforcement plates.

[0020] The effect achieved by the above components is: through the setting of the nut and the reinforcement plate, the screw can be more stable when rotating and is not prone to abnormal shaking, so that the position of the card plate can be better driven to limit and fix the reinforcement device. At the same time, after the card plate and the card slot are connected, the nuts on both sides of the screw are rotated so that the nuts are contacted and squeezed by the card plate.

[0021] Preferably, one end of the screw rod is fixedly connected to an operating block, and a surface of the operating block is provided with a plurality of evenly distributed anti-slip protrusions.

[0022] The effect achieved by the above components is: through the setting of the operating block, the screw can be rotated more conveniently and quickly, thereby better connecting the card plate with the card slot on the fixed rod, improving the convenience of using the screw, and making the reinforcement device more efficient during assembly, thereby improving the functionality of the connecting device.

[0023] Preferably, the clamping method of the blade seam welding fixture comprises the following steps: Step 1: When seam welding the blade, first install the reinforcement device on the workbench with the help of the connecting device, first insert the two fixing rods on the surface of the slide rail into the two fixing frames on the surface of the workbench respectively, and then rotate the operating block fixedly connected on the screw rod to make the screw rod connected to the mounting block rotate. Because the limit rod on the mounting block limits the sliding direction of the card plate, the card plates on both sides of the screw rod will move away from each other until the two card plates are respectively connected with the card grooves on the two fixing rods; Step 2, then place the inner ring of the blade on the fixed head at one end of the clamping rod frame, and then operate and start the fixed head to make the fixed head open to fix the blade, and then start the servo motor on the slide rail. Because the first gear is meshed with the second gear, the rotation of the output end of the servo motor will drive the rotation of the first gear, thereby causing the rotating rod on one side of the slide rail to rotate. At this time, the two connecting belts on the rotating rod are wound around the rotating rod, so that the connecting belt is wound on the take-up reel on the surface of the rotating rod. At this time, the assembly plate connected to the mounting rod at one end of the connecting belt will slide on the inner wall of the slide rail, driving the stabilizing plate on the assembly plate to approach the workpiece, and at the same time, the sliding rod on the assembly plate slides on the limit plate on the surface of the slide rail, so that the sliding rod and the sliding hole on the limit plate slide, and the assembly plate is limited and stabilized accordingly; Step 3: When the assembly plate slides, the roller on the arc surface of the rotating shaft on the assembly plate just contacts the leaf ring on the blade, and then the machine is started to rotate the clamping rod frame, the workpiece is rotated, and the corresponding weld position is seam welded.

[0024] In summary, the beneficial effects of the present invention are: In the present invention, when the blade is seam-welded, the outer ring of the blade can be better kept relatively stable, and shaking between components is not likely to occur, so that the weld position can be better processed and welded, the processing effect and the use effect of the finished product are improved, and the work efficiency of the blade processing and the use effect of the equipment are further improved.

[0025] In the present invention, the reinforcement device is more convenient to assemble when in use, and can more efficiently limit and stabilize the blade seam welding, thereby improving the convenience of using the reinforcement device. It is also convenient for daily disassembly and assembly of the reinforcement device, and is convenient for staff to inspect and maintain it, thereby ensuring the normal use of the reinforcement device.

Through the setting of the operating block 611, the screw rod 64 can be rotated more conveniently and quickly, and then the card plate 65 is better connected to the card slot 67 on the fixing rod 62, which improves the convenience of using the screw rod 64, and also makes the reinforcement device 5 more efficient during assembly, thereby improving the functionality of the connecting device 6.

[0034] Working principle: When seam welding the blade, first install the reinforcement device 5 on the workbench 2 with the help of the connecting device 6, first insert the two fixing rods 62 on the surface of the slide rail 51 into the two fixing frames 61 on the surface of the workbench 2 respectively, and then rotate the operating block 611 fixedly connected on the screw 64 to make the screw 64 connected to the mounting block 63 rotate. Because the limit rod 66 on the mounting block 63 limits the sliding direction of the card plate 65, the card plates 65 on both sides of the screw 64 will move away from each other until the two card plates 65 are respectively engaged with the card grooves 67 on the two fixing rods 62, and then place the inner ring of the blade on the fixed head 4 at one end of the clamping rod frame 3, and then operate and start the fixed head 4 to make the fixed head 4 open to fix the blade, and then start the servo motor 512 on the slide rail 51. Because the first gear 511 is meshed with the second gear 513, the rotation of the output end of the servo motor 512 The first gear 511 is driven to rotate, thereby rotating the rotating rod 510 on one side of the slide rail 51. At this time, the two connecting belts 59 on the rotating rod 510 are wound around the rotating rod 510, so that the connecting belt 59 is rolled up on the take-up reel 520 on the surface of the rotating rod 510. At this time, the assembly plate 54 connected to the mounting rod 58 at one end of the connecting belt 59 will slide on the inner wall of the slide rail 51, driving the stabilizing plate 55 on the assembly plate 54 to approach the workpiece. At the same time, the sliding rod 519 on the assembly plate 54 slides on the limiting plate 517 on the surface of the slide rail 51, so that the sliding rod 519 and the sliding hole 518 on the limiting plate 517 slide, and the assembly plate 54 is correspondingly limited and stabilized. When the assembly plate 54 slides, until the roller 57 on the arc surface of the rotating shaft 56 on the assembly plate 54 just contacts the leaf ring on the blade, then the machine is started to rotate the clamping rod frame 3, the workpiece is rotated, and the corresponding weld position is seam welded.
