Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically, to an intelligent welding system for the stator core of a wind turbine generator. Background Technology

[0002] The stator core is a crucial component of a wind turbine. Its main function is to form a closed loop of magnetic field lines generated by the rotor during power generation. Electromagnetic wires wound within the slots of the stator core cut these magnetic field lines, thereby inducing a current within the wires. Stator cores can be constructed as integral, segmented, or laminated structures.

[0003] Before welding, the stator cores of wind turbines need to be manually aligned coaxially by multiple sets of stator cores. Then, a tightening device is used to tighten and press the aligned stator cores together. Since several winding plates are evenly fixed on the inner circumference of the stator core, it is necessary to ensure that the corresponding winding plates on the inner circumference of each set of stator cores are aligned. Manual alignment is inefficient and has a high error rate, which affects the subsequent welding quality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an intelligent welding system for wind turbine stator cores. This system forms stator core sections by fitting matching fixing rings onto the circumferential side of each stator core. Each set of stator core sections is then slidably fed onto a horizontal tube. Under the weight of the heavier, less-than-ideal arc section, the stator core section rotates around the horizontal tube until the less-than-ideal arc section is vertically downward, achieving rapid alignment of each core body. This facilitates subsequent tightening welding, improving welding efficiency and quality.

[0036] Example 1, please refer to Figure 1-15 The present invention provides the following technical solutions: A smart welding system for the stator core of a wind turbine generator, specifically, includes a welding frame 1 and a rotating frame 2 rotatably mounted on the welding frame 1; the rotating frame 2 includes a rotating plate 3; an arc-shaped guide tube 4 is uniformly fixed through one side of the rotating plate 3; an outer guide sleeve 5 is connected to the inner circumferential side of the arc-shaped guide tube 4; and a sliding part 6 is slidably arranged between each outer guide sleeve 5.

[0037] A horizontal tube 7, coaxial with the arc-shaped guide tube 4, is fixed on the other opposite side of the rotating plate 3; several grooves 8 are evenly opened on the outer circumference of the horizontal tube 7; a pressing part 9 that slides and engages with the grooves 8 is slidably arranged inside the horizontal tube 7.

[0038] A plurality of stator core sections 10 are slidably disposed on the outer periphery of the horizontal tube 7; the stator core section 10 includes a core body 11; a plurality of positioning grooves 12 are evenly distributed on the outer periphery of the core body 11; the coaxial positioning grooves 12 form a welding groove; a fixing ring is disposed on the outer periphery of the core body 11; the fixing ring is composed of a superior arc section 13 and a inferior arc section 14; the inferior arc section 14 is heavier than the superior arc section 13; a rubber ring 15 is fixed to the inner wall of the fixing ring and fits with the outer periphery of the core body 11; a plurality of rubber blocks 16 are evenly fixed to the inner wall of the rubber ring 15 and are tightly inserted into the corresponding positioning grooves 12; a plurality of winding plates 17 are evenly fixed to the inner periphery of the core body 11; the ends of each winding plate are curved and can slide and rotate freely along the outer periphery of the horizontal tube 7.

[0039] Working principle of this embodiment: By fitting a matching fixing ring to the side of each group of iron core bodies 11 to form a stator iron core part 10, each group of stator iron core parts 10 is slidably fed into the horizontal tube 7 in sequence. Under the gravity of the heavier inferior arc part 14, the stator iron core part 10 is driven to rotate around the horizontal tube 7 until the inferior arc part 14 is vertically downward, so as to achieve rapid alignment of each group of iron core bodies 11, which facilitates the normal progress of subsequent tightening welding and improves welding efficiency and quality.

[0040] By controlling the pressing part 9 to slide towards the rotating plate 3, the aligned stator core parts 10 are pressed together. By controlling the sliding part 6 to slide towards the rotating plate 3, the arc plate 41 slides along the inside of the arc guide tube 4, squeezing the fixing ring off the core body 11. At the same time, the core body 11 is further fixed and limited, improving the stability of subsequent welding.

[0041] Example 2, please refer to Figure 1-15This second embodiment is an improvement on the first embodiment. Specifically, a servo motor 18 is fixed to the side of the rotating plate 3; a lead screw 19 is fixed to the output end of the servo motor 18; the pressing part 9 includes a guide 20 that slides with the inner wall of the horizontal tube 7 and a telescopic part 21; the guide 20 includes a slide plate 22 that slides with the inner wall of the horizontal tube 7; a sliding cavity 23 is opened in the inner wall of the horizontal tube 7; the telescopic part 21 includes a slip ring 24 that slides with the sliding cavity 23; a plurality of slide rails 25 that slide with the slide groove 8 are evenly fixed to the periphery of the slide plate 22; a fixing ring 26 is fixed to the side of the slip ring 24; a pressure plate 27 that slides with the slide groove 8 is evenly slidably disposed through the periphery of the fixing ring 26; the thickness of the pressure plate 27 is greater than the gap between two adjacent winding plates 17.

[0042] A drive motor 28 is fixedly mounted on the side of the rotating plate 3; a first screw 29 is fixedly mounted on the output end of the drive motor 28; a first screw hole 30 is opened on the side of the sliding plate 22 to rotate with the screw 19; a number of compression springs 31 are evenly fixedly connected between the end of the fixing ring 26 and the inner wall of the sliding cavity 23; a number of guide grooves 32 that slide with the pressure plate 27 are evenly opened on the periphery of the fixing ring 26; a storage groove 33 that communicates with the corresponding guide groove 32 is opened on the periphery of the fixing ring 26; an insert plate 34 that inserts into the storage groove 33 is fixed on the top of the pressure plate 27; a return spring 35 is symmetrically fixed between the insert plate 34 and the bottom surface of the storage groove 33.

[0043] A ball head 36 is fixed to the bottom of the pressure plate 27; a first guide tube 37 and a second guide tube 38, which are coaxial with the first screw hole 30, are fixed to the side of the slide plate 22 in sequence; the connection between the first guide tube 37 and the second guide tube 38 is rounded.

[0044] The sliding part 6 includes a fixed plate 39; the side of the fixed plate 39 has a second screw hole 40 that is threadedly engaged with the first screw 29; a plurality of arc-shaped plates 41 that are evenly fixed on the side of the fixed plate 39 and are slidably engaged with the corresponding outer guide sleeves 5; an inner guide sleeve 42 that is slidably engaged with the outer guide sleeves 5 is fixed on the inner circumferential side of the arc-shaped plate 41; a welding groove 74 is provided on the inner wall of the inner guide sleeve 42; and an avoidance groove 43 that communicates with the inner guide sleeve 42 is provided on the outer circumferential side of the arc-shaped plate 41.

[0045] A welding gap is left between the welding groove 74 and the bottom of the welding groove to facilitate the smooth reset of the sliding part 6 later.

[0046] Working principle of this embodiment two: In the initial state, under the elastic force of the compression spring 31, the slip ring 24 is pressed against the inner wall of the sliding cavity 23. At this time, the second guide tube 38 is disengaged from each group of ball heads 36. Under the elastic force of the reset spring 35, the insert plate 34 is driven into the receiving groove 33. In this state, each group of ball heads 36 is placed outside the second guide tube 38.

[0047] By controlling the start servo motor 18 to drive the lead screw 19 to rotate, the guide member 20 is driven to slide towards the rotating plate 3, so that the second guide tube 38 slides towards the ball head 36, until each group of ball heads 36 is tangent to the outer peripheral side of the second guide tube 38. When the ball head 36 slides along the second guide tube 38 to the first guide tube 37, during this process, each group of ball heads 36 is squeezed, which drives the corresponding pressure plate 27 to slide away from the second guide tube 38. The reset spring 35 is stretched, and the pressure plate 27 slides into the corresponding slide groove 8. During this process, the telescopic member 21 is driven to slide towards the rotating plate 3, and the compression spring 31 is compressed. Each group of unfolded pressure plates 27 presses against the core body 11 on the aligned stator core part 10, so that each group of stator core parts 10 slides and tightens along the horizontal tube 7, until it is pressed between the pressure plate 27 and the rotating plate 3.

[0048] By controlling the start drive motor 28 to drive the first screw 29 to rotate, the sliding part 6 slides towards the rotating plate 3, the arc plate 41 slides along the corresponding arc guide tube 4, and each set of fixing rings is squeezed out from the iron core body 11. The inner guide sleeve 42 slides into the corresponding welding groove 74, which further improves the stability of the iron core body 11.

[0049] Example 3, please refer to Figure 1-15 This embodiment three is an improvement on embodiment two. Specifically, the arc plate 41 has a discharge port 44 on its circumferential side; the arc plate 41 has a hollow structure inside; a first U-shaped tube 45 connected to the arc plate 41 is fixed inside the discharge port 44; an inlet pipe 46 and a drain pipe 47 are fixed sequentially at the end of one arc plate 41; and a second U-shaped tube 48 is connected between the other adjacent arc plates 41.

[0050] The inlet pipe 46 and the outlet pipe 47 are connected to the external conveying pipe and the external drain pipe, respectively. Cold water is conveyed to the inlet pipe 46 through the external conveying pipe, and the water that has completed the heat exchange is discharged through the outlet pipe. The arc plate 41, the first U-shaped pipe 45, the inlet pipe 46, the outlet pipe 47 and the second U-shaped pipe 48 together form a serpentine heat exchange channel.

[0051] A conical guide sleeve 49 is fixed to the side of the rotating plate 3; several guide ports 50 are evenly opened on the circumference of the conical guide sleeve 49; several guide holes 51 are evenly opened on the circumference of the conical guide sleeve 49; an insert rod 52 is slidably arranged inside the guide hole 51; a baffle 53 is fixed to the top of the insert rod 52, and a guide ball 54 is fixed to its bottom; an inclined guide plate 55 is fixed inside the clearance groove 43; a straight guide plate 56 is fixed to the end of the inclined guide plate 55; a support spring 57 sleeved on the insert rod 52 is fixedly connected between the baffle 53 and the outer circumference of the conical guide sleeve 49.

[0052] Working principle of this embodiment three: Cold water is introduced into the arc-shaped plate 41 through the liquid inlet pipe 46, which exchanges heat with the welding position, reducing the heat of the iron core body 11 and making it easier to safely remove the welded iron core body 11 and reducing waiting time.

[0053] During the welding process, small welding particles are left in the clearance groove 43. The control start drive motor 28 drives the first screw 29 to rotate in the opposite direction, causing the guide member 20 to slide towards the rotating plate 3. The guide ball 54 slides on the straight guide plate 56. At this time, the support spring 57 is stretched. When the inclined guide plate 55 slides to contact the guide ball 54, the discharge port 44 is collected into the corresponding arc-shaped guide tube 4. Under the elastic reset force of the support spring 57, the insertion rod 52 is driven to slide away from the corresponding guide hole 51, so that the guide ball 54 enters the clearance groove 43. The clearance groove 43 is provided with bristles on its peripheral side. The guide member 20 continues to slide and reset. The small particles of debris in the clearance groove 43 are swept into the conical guide sleeve 49 by the bristles on the guide ball 54 through the discharge port 44, and then fall into the collection box 63 through the guide port 50 and the guide plate 62 in sequence to be collected.

[0054] Example 4, please refer to Figure 1-15 This fourth embodiment is an improvement on the third embodiment as follows: Specifically, the welding frame 1 includes a base 58; a support plate 59 is fixed on the surface of the base 58; an annular groove 60 is provided on the outer periphery of the rotating plate 3; an installation port 61 is provided on the side of the support plate 59 to rotatably engage with the annular groove 60; a guide plate 62 is fixed on the side of the support plate 59; a collection box 63 is placed on the surface of the base 58; a stepper motor 64 is fixed on the bottom surface of the support plate 59; a gear 65 is fixed on the output end of the stepper motor 64; and a gear ring 66 that meshes with the gear 65 is fixed on the side of the rotating plate 3.

[0055] A U-shaped plate 67 is fixed to the top of the support plate 59; a second screw 68 is rotatably installed through the inner wall of the U-shaped plate 67; a welding motor 69 is fixedly installed at one end of the U-shaped plate 67; the output end of the welding motor 69 is fixedly connected to one end of the second screw 68; a controller 70 is fixed to the other end of the U-shaped plate 67; an adjustment seat 71 is rotatably installed on the second screw 68 and slides with the top of the inner wall of the U-shaped plate 67; an electric push rod 72 is fixed to the bottom of the adjustment seat 71; a welding head 73 is fixedly installed at the telescopic end of the electric push rod 72.

[0056] Working principle of Example 4: After alignment and tightening, a set of weld grooves on each group of iron core bodies 11 are located directly below the welding head 73. The electric push rod 72 is activated to lower the welding head 73 to the welding position of the weld groove. The welding motor 69 is activated to drive the second screw 68 to rotate, causing the adjusting seat 71 to slide along the top of the U-shaped plate 67, thereby driving the welding head 73 to weld along the length of the weld groove. After the welding of a set of weld grooves is completed, the electric push rod 72 is activated to rise and reset. Then, the stepper motor 64 is activated to drive the gear 65 to rotate. Through the cooperation of the gear 65 and the gear ring 66, the rotating frame 2 and the clamped and fixed iron core body 11 are driven to rotate synchronously at a certain angle, so that the adjacent unwelded weld grooves rotate directly below the welding head 73. The above operation is repeated to complete the welding of each set of weld grooves.
