Description

Technical Field:

[0002] The present invention relates to the technical field of wind power generation, and particularly to a blade web positioning tooling for positioning a conventional large web. Background Art:

[0004] With the development of wind power generation technology, higher and higher requirements are put forward for the strength and assembly efficiency of wind turbine blades. During the manufacturing process of wind turbine blades, each blade needs to be installed with a web to improve the stress strength of the blade, and relevant positioning tooling is required to assist in the installation of the web onto the blade. The existing positioning tooling is either not highly automated and requires multiple people to cooperate, or the positioning and / or clamping is not precise, which ultimately affects the positioning error of the web, the installation efficiency, and the glue extrusion bonding effect. Summary of the Invention:

[0006] To overcome the above problems, it would be advantageous for the present invention to provide a blade web positioning tooling with high production efficiency and low assembly scrap rate.

[0007] For this purpose, the present invention provides a blade web positioning tooling, which includes a main steel frame, multiple pairs of positioning arms, and multiple pairs of suction cup arms. Its characteristics are as follows:

[0008] Each suction cup arm includes a suction cup mounting arm, a mounting arm driving device, and multiple vacuum suction cup devices. Among them, the suction cup mounting arm is rotatably mounted on the main steel frame, and the mounting arm driving device is drivingly connected to the suction cup mounting arm so that it can be switched between an inward clamping position and an outward opening position;

[0009] Each positioning arm includes a large arm steel frame and a telescopic positioning arm. Among them, the large arm steel frame is rotatably mounted on the main steel frame between an extended support position and a retracted storage position. The telescopic positioning arm includes a positioning lifting device, a three-way adjustable leg base, and a large arm base. The positioning lifting device is mounted on the large arm steel frame and has a telescopic jack that can move between a downward extended position and an upward retracted position. The three-way adjustable leg base includes a lifting docking base located at its upper end to receive and support the telescopic jack.

[0010] In the present invention, since the positioning and lifting device is installed on the boom steel frame and its telescopic push rod is received on the lifting docking base of the three-way adjustable leg base, when the telescopic push rod moves from the upward retracted position to the downward extended position, the telescopic positioning arm becomes longer (i.e., higher relative to the ground), and the main steel frame drives the suction cup arm to move upward; when the telescopic push rod moves from the downward extended position to the upward retracted position, the telescopic positioning arm becomes shorter (i.e., lower relative to the ground), and the main steel frame drives the suction cup arm to move downward; through this up and down adjustment, the suction cup arm can adsorb and position the blade web at an appropriate height; moreover, the length adjustment of the telescopic positioning arm by the positioning and lifting device has good stability, high strength, high precision and impact resistance. The setting of the three-way adjustable leg base enables the position of the lifting docking base to be adjusted in three directions: front and back, up and down, and left and right, so as to accurately receive the telescopic push rod. In addition, the setting of the boom base enables the positioning boom to be fixed on both sides of the blade production mold through it.

[0011] Further, the positioning and lifting device includes an electric cylinder mounting seat fixed on the boom steel frame, an electric cylinder having a telescopic push rod, and a servo motor for driving the electric cylinder. Among them, a guiding and stress-bearing seat is also installed on the electric cylinder mounting seat, and the telescopic push rod is installed through the guiding and stress-bearing seat.

[0012] Through the above structural setting, the operations of making the telescopic positioning arm longer and shorter are very convenient, and the use is safe and reliable.

[0013] Still further, the three-way adjustable leg base successively includes a lifting docking base, a mounting base, a connecting base and a connecting leg from top to bottom. Among them, the lifting docking base is installed on the mounting base in a front and back adjustable manner, the mounting base is installed on the connecting base in an up and down adjustable manner, the connecting base is installed on the connecting leg in a left and right adjustable manner, and the connecting leg is fixed on the boom base.

[0014] Through the above structural setting, the position of the lifting docking base can be adjusted in three directions: front and back, up and down, and left and right.

[0015] Even further, front and back adjustment kidney-shaped holes are provided on the mounting base, and the lifting docking base is installed on the mounting base in a front and back adjustable manner by means of bolts tightened through the front and back adjustment kidney-shaped holes; a height adjustment bolt is also installed on the mounting base, and a receiving seat adapted to the height adjustment bolt is provided on the connecting base; left and right adjustment kidney-shaped holes are provided on the connecting leg, and the connecting base is installed on the connecting leg in a left and right adjustable manner by means of bolts tightened through the left and right adjustment kidney-shaped holes; the three-way adjustable leg base further includes a limiting member movably installed on the connecting base and adapted to radially abut against the height adjustment bolt.

[0016] With the above structural arrangement, it is very convenient to adjust the position of the jacking docking base in three directions: front-back, up-down, and left-right by adjusting the position of the bolts. Moreover, the height adjustment bolts can be limited by the limit members.

[0017] Furthermore, the boom steel frame is rotatably fixed to the main body steel frame via a rotary mounting assembly on the inner side close to the main body steel frame. The rotary mounting assembly includes an upper rotary mounting base and a lower rotary mounting base fixed to the main body steel frame, and a long rotating shaft fixed to the boom steel frame. The upper and lower ends of the long rotating shaft are respectively rotatably installed in the upper rotary mounting base and the lower rotary mounting base.

[0018] With this structural arrangement, the conversion of the boom steel frame positioning the boom between the deployed support position and the retracted storage position becomes easy and smooth.

[0019] Still further, the above-mentioned blade web positioning tooling further includes a deployed positioning device for positioning the boom steel frame in the deployed support position. The deployed positioning device includes a triangular bracket installed on the main body steel frame, a spring pin mounting seat installed on the triangular bracket, a deployed positioning seat installed on the boom steel frame, and a spring pin fixing the deployed positioning seat and the spring pin mounting seat together.

[0020] With the above structural arrangement, when the positioning boom is in the deployed support position, the boom steel frame can be fixed relative to the main body steel frame through the spring pin, so that the positioning boom can stably serve as the support and positioning of the entire tooling at this position.

[0021] Even further, the mounting arm driving device includes an electric cylinder, a front mounting seat of the electric cylinder, and a rear mounting seat of the electric cylinder. Among them, the rear mounting seat of the electric cylinder is detachably fixed to the main body steel frame, the front mounting seat of the electric cylinder is detachably fixed to the suction cup mounting arm, and the front and rear ends of the electric cylinder are respectively rotatably connected to the front mounting seat of the electric cylinder and the rear mounting seat of the electric cylinder.

[0022] With the above structural arrangement and the drive of the electric cylinder, the suction cup mounting arm can be reliably and controllably converted between the inward clamping position and the outward opening position, with high positioning accuracy, high strength, impact resistance, and good stability.

[0023] Also further, the above-mentioned suction cup arm further includes a limiting member installed on the main body steel frame for limiting the suction cup mounting arm. The limiting member has a limiting cavity with an opening facing outwards.

[0024] With the arrangement of this limiting member, the suction cup mounting arm can be limited no matter which position it is in, avoiding left-right shaking.

[0025] Furthermore, the vacuum suction cup device includes a suction cup mounting base and a vacuum suction cup fixed to the suction cup mounting base. Among them, the suction cup mounting base is mounted on the suction cup mounting arm and includes a front-back adjustment base, an angle adjustment seat, and a left-right adjustment seat. Among them, the front-back adjustment base is fixed to the suction cup mounting arm via a fastening component. The angle adjustment seat is adjustably mounted on the front-back adjustment base in the height direction. A vacuum suction cup is fixed on the left-right adjustment seat and is left-right adjustably mounted on the angle adjustment seat.

[0026] Through the above structural settings, it is possible to adjust the front-back position, tilt angle, and left-right position of the vacuum suction cup thereon by adjusting the front-back adjustment base, the angle adjustment seat, and the left-right adjustment seat respectively, so as to complete the adjustment of the adsorption fit degree of the web, with high positioning accuracy, reaching a positioning accuracy of 0.01 mm.

[0027] Furthermore, front-back adjustment waist-shaped holes for adjusting its front-back mounting position are provided on the front-back adjustment base; angle adjustment waist-shaped holes for adjusting its height mounting position are provided on the angle adjustment seat; left-right adjustment waist-shaped holes for adjusting its left-right mounting position are provided on the left-right adjustment seat.

[0028] Through the setting of these waist-shaped holes, the position adjustment in the above three directions is realized, so as to better adsorb the web, and the adjustment is very convenient.

[0029] Furthermore, the front-back adjustment base is configured as an L shape or a straight line shape, which can adapt to the adjustment and fitting of three degrees of freedom of the product.

[0030] Furthermore, the above-mentioned blade web positioning tooling further includes a web positioning anti-detachment clamp, which is suspended and mounted on the main body steel frame and includes a pair of hook claws for clamping or loosening the upper part of the blade web (i.e., the bonding corner of the SS or PS side flange of the blade web).

[0031] Through the setting of the web positioning anti-detachment clamp, the tooling can not only clamp the web by the suction cup arm, but also clamp the web from above by the web positioning anti-detachment clamp, so that the positioning of the blade web is more reliable and stable.

[0032] Furthermore, the above-mentioned blade web positioning tooling further includes a web pressing device, which includes a mounting connecting plate fixed to the main body steel frame, a pressing mounting seat fixed to the mounting connecting plate, an adjustable screw rod adjustably mounted on the pressing mounting seat in height, and a lower pressing plate mounted at the lower end of the adjustable screw rod.

[0033] Through the above structural settings, it is possible to conveniently adjust the position of the lower pressing plate to effectively press the web, so as to control the thickness and area of the bonding glue.

[0034] These and other aspects of the present invention will be more clearly elucidated by referring to the embodiments described below. BRIEF DESCRIPTION OF THE DRAWINGS:

[0053] The following will describe the detailed implementation manners of the present invention in conjunction with the drawings.

[0054] As Figure 1 shown, the blade web positioning tooling according to a specific embodiment of the present invention includes a main body steel frame 1, multiple pairs of positioning arms 3, and multiple pairs of suction cup arms 5. However, for the sake of clarity of the figure, Figure 1 only one pair of positioning arms 3 is shown on its front side, and the suction cup arms 5 are not shown in pairs in Figure 1 , and only the suction cup arms 5 located on the right side of the main body steel frame 1 are shown.

[0055] As Figures 1 to 4 shown, each positioning arm 3 includes a large arm steel frame 30 and a telescopic positioning arm 32. The large arm steel frame 30 is rotatably fixed to the main body steel frame 1 between the unfolded support position (see Figure 1 ) and the folded storage position (not shown in the figure). The telescopic positioning arm 32 includes a positioning jacking device 2, a three-way adjustable leg base 34, and a large arm base 36. As Figures 2 to 4 shown, the positioning jacking device 2 is installed on the large arm steel frame 30 and has a telescopic jacking rod 21 that can move between the downward extended position and the upward retracted position. The three-way adjustable leg base 34 includes a jacking docking base 31 located at its upper end to receive and support the telescopic jacking rod 21.

[0056] In the present invention, since the positioning and lifting device 2 is installed on the boom steel frame 30 and its telescopic rod 21 is received on the lifting docking base 31 of the three-way adjustable leg base 34, when the telescopic rod 21 moves from the upward retracted position to the downward extended position, the entire telescopic positioning arm 32 of the positioning boom 3 becomes longer (i.e., higher relative to the ground), and the main body steel frame 1 moves upward with the suction cup arm 5; when the telescopic rod 21 moves from the downward extended position to the upward retracted position, the telescopic positioning arm 32 becomes shorter (i.e., lower relative to the ground), and the main body steel frame 1 moves downward with the suction cup arm 5; through such upward and downward adjustment of the suction cup arm 5, the suction cup arm 5 can adsorb and position the blade web (not shown in the figure) at an appropriate height; moreover, by adjusting the length of the telescopic positioning arm 32 through the positioning and lifting device 2, it has good stability, high strength, high precision, and impact resistance. The setting of the three-way adjustable leg base 34 enables the position of the lifting docking base to be adjusted in three directions: front and back, up and down, and left and right, so as to accurately adapt to different on-site installation environments and different blade shapes. In addition, the setting of the boom base 36 can fix the three-way adjustable leg base 34 on both sides of the blade production mold (not shown in the figure).

[0057] It should be noted that a plurality of mounting waist-shaped holes 360 are provided on the boom base 36 for adjusting its position on the blade web production mold to meet the position adjustment within the error range.

[0058] As Figure 5 shown and referring to Figure 1 , the positioning and lifting device 2 includes an electric cylinder 20 having a telescopic rod 21, an electric cylinder mounting seat 22 fixed on the boom steel frame 30, and a servo motor 24 for driving the electric cylinder 20. Among them, a guiding and stress-bearing seat 26 through which the telescopic rod 21 passes is also installed on the electric cylinder mounting seat 22. In this embodiment, the end of the telescopic rod 21 has a pin 210, and the pin 210 can ride on the pin seat 310 of the lifting docking base 31. Through the above structural setting, the operations of making the telescopic positioning arm 32 longer and shorter are very convenient, and it is safe and reliable to use.

[0059] As Figure 5 , Figure 6 and Figure 7 shown and referring to Figures 1 to 4 , the three-way adjustable leg base 34 successively includes a lifting docking base 31, a mounting base 33, a connecting base 35, and a connecting leg 37 from top to bottom. Among them, the lifting docking base 31 is adjustably installed on the mounting base 33 in the front and back directions, the mounting base 33 is adjustably installed on the connecting base 35 in the up and down directions, the connecting base 35 is adjustably installed on the connecting leg 37 in the left and right directions, and the connecting leg 37 is fixed on the boom base 36.

[0060] Specifically, as Figure 6 shown and referring toFigure 5 and Figure 7 In this embodiment, a front-back adjustment kidney-shaped hole 331 is provided on the mounting base 33. The jacking docking base 31 is mounted on the mounting base 33 in a front-back adjustable manner by means of bolts (not shown in the figure) that pass through the front-back adjustment kidney-shaped hole 331 and are tightened thereon. A height adjustment bolt 335 is also installed on the mounting base 33, and a receiving seat 355 adapted to the height adjustment bolt 335 is provided on the connecting base 35. A left-right adjustment kidney-shaped hole 375 is provided on the connecting leg 37. The connecting base 35 is mounted on the connecting leg 37 in a left-right adjustable manner by means of bolts 377 that pass through the left-right adjustment kidney-shaped hole 375 and are tightened thereon. The three-way adjustable leg base 34 further includes a limiting member 337 that is movably installed on the connecting base 35 and is adapted to radially abut against the height adjustment bolt 335. The limiting member 337 can be a limiting bolt. It should be understood that a limiting hole 357 adapted to receive the limiting member 337 is also provided on the connecting base 35. When the height adjustment bolt 335 is adjusted to a certain height, the limiting member 337 passes through the limiting hole 357 and is tightened inward to abut against the height adjustment bolt 335. Through the above structural settings, it is very convenient to adjust the position of the jacking docking base 31 in three directions: front-back, up-down, and left-right, and the height adjustment bolt 335 can also be limited by the limiting member 337.

[0061] It should be noted that when using this tooling, first fix the boom base 36 of the telescopic positioning arm 32 on the ground on both sides of the web die, adjust the three directions of the three-way adjustable leg base 34 to meet the position requirements. The other parts of the tooling are used to find the position of the telescopic jack rod 21 of the positioning jacking device 2 under the transportation of a crane. At this time, the telescopic jack rod 21 is not received on the three-way adjustable leg base 34. As Figure 4 shown, when the telescopic jack rod 21 is aligned with the jacking docking base 31 of the three-way adjustable leg base 34 and received therein, the crane lowers the tooling. At this time, adjust the length of the telescopic jack rod 21 of the positioning jacking device 2 to extend or retract, so as to adjust the height of the positioning boom 3 to adapt to the size of the web.

[0062] Again, as Figure 2 shown, and with reference to Figure 1, in the present embodiment, the boom steel frame 30 is rotatably fixed to the main body steel frame 1 via a rotary mounting assembly 4 on the inner side thereof close to the main body steel frame 1. The rotary mounting assembly 4 includes an upper rotary mounting base 40 and a lower rotary mounting base 42 fixed to the main body steel frame 1, and a long rotary shaft 41 fixed to the boom steel frame 30. The upper and lower ends of the long rotary shaft 41 are respectively rotatably mounted in the upper rotary mounting base 40 and the lower rotary mounting base 42. Through this structural arrangement, the conversion of the boom steel frame 30 positioning the boom 3 between the deployed support position and the retracted storage position becomes easy and smooth. The rotary mounting assembly 4 further includes bearings and dust covers (not shown in the figure). The bearings are mounted in bearing mounting holes (not shown in the figure) integrally formed with the upper rotary mounting base 40 and the lower rotary mounting base 42 respectively and sleeved on the long rotary shaft 41, and the dust covers are mounted outside the bearing mounting holes.

[0063] As Figure 8 shown, and referring to Figure 2 , in the present embodiment, the blade web positioning tooling further includes a deployed positioning device 6 for positioning the boom steel frame 30 in the deployed support position. The deployed positioning device 6 includes a triangular bracket 61 mounted on the main body steel frame 1, a spring pin mounting seat 63 mounted on the triangular bracket 61, a deployed positioning seat 65 mounted on the boom steel frame 30, and a spring pin 67 fixing the deployed positioning seat 65 and the spring pin mounting seat 63 together. Through the above structural arrangement, when the positioning boom 3 is in the deployed support position, the boom steel frame 30 can be fixed relative to the main body steel frame 1 by the spring pin 67, so that the positioning boom 3 can stably serve as the support and positioning of the entire tooling at this position. It should be noted that although only the deployed positioning device is mentioned here in the deployed support position, it should be understood that in the retracted storage position, there will also be a similar positioning device to position the retracted boom steel frame 30, so as to avoid its being positioned and shaken when not working, i.e., in the storage state.

[0064] As Figures 9 to 15 shown, and referring to Figure 1 , in the present embodiment, each suction cup arm 5 includes a suction cup mounting arm 50, a mounting arm driving device 7, and a plurality of vacuum suction cup devices 8. Each vacuum suction cup device 8 includes a suction cup mounting seat 80 mounted on the suction cup mounting arm 50 and a vacuum suction cup 81 mounted on the suction cup mounting seat 80. The suction cup mounting arm 50 is rotatably mounted on the main body steel frame 1 around a rotary shaft 520 on a fixed seat 52, where the fixed seat 52 is a fixed seat connecting the suction cup mounting arm 50 to the main body steel frame 1. The mounting arm driving device 7 is drivingly connected to the suction cup mounting arm 50, so that the suction cup mounting arm 50 can be in an inward clamping position (see Figure 9 and Figure 10 ) and an outward opening position (see Figure 11 andFigure 12 ) for conversion.

[0065] As Figure 10 and Figure 13 shown, the mounting arm driving device 7 includes an electric cylinder 70, a front mounting seat 71 of the electric cylinder, and a rear mounting seat 72 of the electric cylinder. Among them, the rear mounting seat 72 of the electric cylinder is detachably fixed to the main body steel frame 1, the front mounting seat 71 of the electric cylinder is detachably fixed to the suction cup mounting arm 50, and the electric cylinder 70 is rotatably connected to the front mounting seat 71 and the rear mounting seat 72 of the electric cylinder at its front and rear ends respectively. Through the above structural settings and the driving of the electric cylinder 70, the suction cup mounting arm 50 of the suction cup arm 5 can be stably and controllably converted between the inward clamping position and the outward opening position.

[0066] As Figures 9 to 12 shown, in this embodiment, the suction cup arm 5 further includes a limiting member 9 mounted on the main body steel frame 1 for limiting the suction cup mounting arm 50. The limiting member 9 has a limiting cavity 90 with an opening facing outwards, and the suction cup mounting arm 50 can be located in the limiting cavity 90 regardless of its position, so as to be limited left and right and avoid shaking left and right.

[0067] As Figure 14 shown and referring to Figures 9 to 12 , the suction cup mounting seat 80 includes a front and rear adjustment base 82, an angle adjustment seat 84, and a left and right adjustment seat 86. Among them, the front and rear adjustment base 82 is provided with front and rear adjustment kidney-shaped holes 820 for adjusting its front and rear mounting positions, so that the front and rear adjustment base 82 can be fixed to the suction cup mounting arm 50 via a fastening component 83 passing through the front and rear kidney-shaped holes 820; the angle adjustment seat 84 is provided with angle adjustment kidney-shaped holes 840 for adjusting its height mounting position and further adjusting its mounting angle, so that the angle of the angle adjustment seat 84 can be adjustably mounted on the front and rear adjustment base 82 by means of bolts (not shown in the figure); the left and right adjustment seat 86 is provided with left and right adjustment kidney-shaped holes 860 for the left and right mounting positions, so that the left and right adjustment seat 86 can be adjustably mounted on the angle adjustment seat 84 left and right. The vacuum suction cup 81 is fixed to the left and right adjustment seat 86, and the vacuum suction cup 81 can be finely adjusted in position by means of the above structure so as to properly fit the outer surface of the blade web in the inward clamping position. In short, through the setting of these kidney-shaped holes, it is possible to adjust the front and rear positions, tilt angles, and the adsorption and fitting degree of the vacuum suction cup 81 on it by adjusting the front and rear adjustment base 82, the angle adjustment seat 84, and the left and right adjustment seat 86 respectively. The suction cup positioning accuracy is high, and the positioning accuracy can reach 0.01 mm.

[0068] It should be noted that, as Figure 12As shown, the front and rear adjustment base 82 can be configured as an L shape or a straight shape. In the present embodiment, among the multiple vacuum suction cup devices 8 mounted on each suction cup mounting arm 50, for some of the vacuum suction cup devices 8, the front and rear adjustment base 82 used by the suction cup mounting seat 80 is in an L shape, and for some of the vacuum suction cup devices 8, the front and rear adjustment base 82 used by the suction cup mounting seat 80 is in a straight shape. This is set because adsorbing products require a separate mechanism to complete in special areas, otherwise interference will occur with the blade housing.

[0069] Again, Figure 1 As shown, in the present embodiment, the blade web positioning tooling further includes a web positioning anti - detachment clamp 10. The web positioning anti - detachment clamp 10 is suspended and mounted on the main body steel frame 1 and is configured to include a pair of claw hooks (not shown in the figure) for clamping or releasing the blade web. Through the setting of the web positioning anti - detachment clamp 10, this tooling can not only clamp the web with the suction cup arm, but also clamp the web from above through this web positioning anti - detachment clamp, so that the positioning of the blade web is more reliable and secure.

[0070] As Figure 15 shown, and referring to Figure 9 and Figure 11 , in the present embodiment, the blade web positioning tooling further includes a web pressing - down device 12. The web pressing - down device 12 includes a mounting connecting plate 120 fixed on the main body steel frame 1, a pressing - down mounting seat 121 fixed on the mounting connecting plate 120, an adjustable screw rod 123 height - adjustably mounted on the pressing - down mounting seat 121, and a lower pressing plate 125 mounted at the lower end of the adjustable screw rod 123. Through the above - mentioned structural setting, it is possible to conveniently adjust the position of the lower pressing plate 125 to effectively press down the web. Specifically, as Figure 15 shown, the adjustable screw rod 123 is positioned at the required height by adjusting the upper and lower two adjustable nuts 124 on the adjustable screw rod 123.

[0071] The technical content and technical features of the present invention have been disclosed above. However, it can be understood that under the creative concept of the present invention, those skilled in the art can make various changes and improvements to the above - mentioned structure, including combinations of the technical features separately disclosed or claimed here, and other combinations that obviously include these features. These deformations and / or combinations all fall within the technical field involved in the present invention and within the protection scope of the claims of the present invention.
