Description

Technical Field

[0001] The present invention relates to the technical field of welding tooling, and in particular to a welding tooling for processing wind turbine blades. Background Art

[0002] The welding tooling for wind turbine blade processing refers to a special device that is mainly used for pressurized positioning in the blade web bonding process during the wind turbine blade manufacturing process, and can also be used for positioning support welding technology before welding. The welding process in wind turbine blade processing needs to select different methods according to the material and functional requirements of the components. When welding the transition layer at the bolt connection part of the metal blade, it needs to be filled by arc welding after increasing the bottom hole size. At this stage, when the arc welding process is used for wind turbine blades, the arc welding heat input is large, which can easily cause residual stress in the weld and surrounding materials. In addition, during the welding process, the coating (coating) of the electrode or wire melts and decomposes at high temperature to form a layer of liquid slag covering the surface of the molten pool. After cooling, the slag solidifies into a brittle solid and adheres to the weld surface. The welding slag remaining in the key load-bearing parts will directly reduce the effective load-bearing area, resulting in insufficient structural strength. Summary of the Invention

Each tooling arm is provided with a circular groove for placing the limiting column, and each limiting column is plugged into the circular groove on the corresponding tooling arm. The end of each tooling arm away from the load-bearing arm is set to a hook shape. The placement groove on each tooling arm is in the shape of an oblique seven-character shape, and the two tooling arms are distributed accordingly.

[0005] When the wind turbine blades need to be processed and welded, the wind turbine blades are placed on the side of the tooling tube away from the supporting tube, and then the functional column moves toward the position close to the blocking ring. The functional column drives the connecting tube to move when it moves, and the connecting tube drives the connecting piece to move when it moves, and the connecting piece drives the limiting column to move when it moves. The limiting column drags the tooling arm toward the position of the blocking ring when it moves. The tooling arm is blocked by the path rod when it moves, and the tooling arm opens in the oblique seven-shaped shape of the tooling arm placement slot when it moves. When the tooling arm is opened, it fits toward the inner diameter of the wind turbine blade, and the hook part of the tooling arm fixes the inner ring of the wind turbine blade.

[0006] As a preferred technical solution of the present invention, the functional column is provided with a transmission component for cooperating with the locking component, and a placement cylinder is provided in the transmission component, which is sleeved on the outside of the functional column, and the outside of the supporting cylinder is fixedly connected to the first housing, and the inside of the first housing is provided with a first motor, and the supporting cylinder is movably connected with a first double-conical column, and the output shaft of the first motor is fixedly connected to the first double-conical column, and two corresponding bevel teeth are provided on the first double-conical column, and a gear is fixedly connected to the outside of the first double-conical column.

[0007] When it is necessary to drive the functional column toward the position of the blocking ring, start the first motor. The model of the first motor can be referenced as 57HS22-IP67, and then the first motor drives the first double-cone column to rotate. When the first double-cone column rotates, it drives the gear to rotate. When the gear rotates, it drives the placement tube to move toward the inside of the bearing tube through a number of tooth blocks. When the placement tube moves, it drives the functional column toward the position of the blocking ring. When it needs to release the fixation of the wind turbine blade, the first double-cone column drives the gear to rotate in the opposite direction. When the gear rotates in the opposite direction, it drives the placement tube to reset through the tooth blocks. When the placement tube resets, it drives the functional column to reset.

[0008] As a preferred technical solution of the present invention, a floating and blowing assembly for cooperating with the locking assembly is provided inside the tooling cylinder, a single conical column and a fan disk are provided inside the floating and blowing assembly, and the floating dust and impurities of the wind turbine blades can be processed by cooperating with the single conical column and the fan disk. A limiting arm is provided inside the floating and blowing assembly, and there are two limiting arms in total. Each limiting arm is fixedly connected to the inner wall of the bearing cylinder, and each limiting arm is fixedly connected to a second double-conical column at one end away from the bearing cylinder, and each second double-conical column is movably connected to a movable ring, and the movable ring can be limited by the setting of the second double-conical column. There are two air inlet pipes fixedly connected to the supporting cylinder, and each air inlet pipe is fixedly connected to a dust removal cylinder at one end away from the supporting cylinder. The dust removal cylinder can be fixed by the setting of the air inlet pipes. Each dust removal cylinder is fixedly connected to a bearing disk, and each bearing disk is provided with a bearing. The inner ring of the bearing of each bearing disk is fixedly connected to the corresponding single conical column, and each single conical column is engaged with a bevel tooth on the movable ring. Each single conical column is fixedly connected to a fan disk at one end away from the movable ring, and the bevel teeth on each movable ring away from the single conical column are engaged with the corresponding bevel teeth on the first double conical column.

[0009] When the first double-cone column rotates, the conical teeth on the first double-cone column drive the single-cone column to rotate, and the single-cone column drives the fan disk to rotate when it rotates. When the fan disk rotates, it draws the air outside the carrier cylinder into the dust collector along the air inlet pipe. The air inside the dust collector is blown toward the fixed wind turbine blades through the rotation of the fan disk, and then the fan disk drives the blown air to clean the floating dust and impurities on the wind turbine blades when it rotates.

[0010] As a preferred technical solution of the present invention, a touch assembly for cooperating with the anti-emission assembly is provided inside the carrying tube, and a second housing is provided inside the touch assembly, which is fixedly connected to the carrying tube. A second motor is provided inside the second housing, and a transmission column is movably connected to the carrying tube, and the output shaft of the second motor is fixedly connected to the transmission column. The end of the support leg away from the second motor is fixedly connected to the connecting plate, and the connecting plate can be fixed by the arrangement of the transmission column. A plurality of connecting blocks are provided inside the connecting plate, and each connecting block is fixedly connected to the connecting plate. A touch plate is fixedly connected to the functional column, and a plurality of touch blocks are fixedly connected to the outer side of the touch plate. When the functional column moves into the interior of the connecting plate, the touch block fits with the connecting block. Two annular grooves for placing rotating columns are provided on the placement tube, and two placement rings are fixedly connected to the outer side of the functional column. Each placement ring is fixedly connected to one end corresponding to the placement tube with a plurality of rotating columns, and the end of each rotating column away from the placement ring is inserted into the corresponding annular groove of the placement tube. The arrangement of the rotating columns can prevent the functional column from interfering with the placement tube when it rotates.

[0011] When the wind turbine blade welding requires stress relief, the functional column enters the interior of the connecting block when it moves, and then the connecting block fits with the touch block on the functional column, and the second motor is started. The second motor model can refer to 6SN1145-1AA00-0. The second motor drives the transmission column to rotate, and the transmission column drives the connecting plate to rotate when it rotates, and the connecting plate drives the connecting block to rotate when it rotates, and the connecting block drives the touch block to rotate when it rotates, and the touch block drives the touch plate to rotate when it rotates, and the touch plate drives the functional column to rotate when it rotates, and the functional column drives the placement ring to rotate when it rotates, and the placement ring drives the rotating column to rotate along the ring groove of the placement cylinder when it rotates.

[0012] As a preferred technical solution of the present invention, a stress relief component for eliminating welding stress is provided on the functional column, and a striking hammer and a telescopic ball are provided in the stress relief component. Vibration can be generated by the cooperation of the striking hammer and the telescopic ball to eliminate the welding stress. An oscillation disk is provided in the stress relief component, and the oscillation disk is fixedly connected to the outer side of the functional column. A groove ring is highly connected to the blocking ring, and a plurality of blocking balls are fixedly connected to the end of the groove ring away from the blocking ring. A plurality of oscillation cylinders are correspondingly fixedly connected to the oscillation disk, and a limiting ring is inserted into the interior of each oscillation cylinder, and a striking hammer is fixedly connected to each limiting ring.

The collision column is inserted into the oscillation cylinder, and when the telescopic ball moves to the position corresponding to the blocking ball, the blocking ball fits with the telescopic ball.

[0013] When the functional column enters the interior of the connecting block, the functional column drives the oscillation disk to correspond to the groove ring position at the top of the blocking ring. When the functional column rotates, the functional column drives the oscillation disk to rotate. When the oscillation disk rotates, it drives the oscillation tube to rotate. When the oscillation tube rotates, it drives the limit ring to rotate. The rotation of the limit ring drives the striking hammer to rotate. When the striking hammer rotates, it drives the telescopic ball to rotate through the impact column. When the telescopic ball rotates to the position corresponding to the blocking ball, the blocking ball squeezes the telescopic ball to move toward the inside of the oscillation tube. When the telescopic ball moves, it drives the impact column to move, and then the impact column drives the striking hammer to hit the oscillation tube when it moves, and the striking hammer drives the tension spring to stretch when it moves. When the striking hammer moves to a position away from the blocking ball, the stretched tension spring rebounds and drives the striking hammer to reset, and then the oscillation disk rotates to form a state of cyclic impact and vibration.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention arranges a fixing component, a stress relief component and a touch component. When the welding of the wind turbine blade is completed and stress needs to be eliminated and welding slag needs to be removed, the wind turbine blade is fixed by opening the two tooling arms. The rotation of the functional column is used as a power source to drive the telescopic ball and the blocking ball to squeeze each other. After the telescopic ball is squeezed, the striking hammer continuously strikes the oscillation tube to generate vibration. The vibration generated by the striking hammer eliminates the residual stress in the weld and eliminates the slag on the weld, thereby improving the welding efficiency.

[0016] The present invention arranges a floating blowing assembly. When the first double-cone column cooperates with the placement cylinder and the functional column to open and fix the tooling arm of the wind turbine blade, the conical teeth on the first double-cone column can drive the single-cone column to rotate. When the single-cone column rotates, the fan disk rotates to generate suction. The suction generated by the fan disk draws air into the dust collection cylinder along the air inlet pipe. The air in the dust collection cylinder is blown toward the wind turbine blade under the action of the fan disk. The airflow blown out of the dust collection cylinder blows away the floating dust and impurities attached to the wind turbine blade, thereby preventing the floating dust and impurities on the wind turbine blade from affecting the welding effect and promoting the convenience of welding.

[0017] Through the cooperation of the transmission component and the touch component, the present invention can drive the placement ring to move along the ring groove of the placement tube when eliminating stress on the wind turbine blade, thereby preventing the functional column from driving the placement tube to rotate when rotating, causing dislocation of the gear and the gear block, avoiding interference during equipment operation, and promoting the stability of equipment operation.

[0018] The present invention provides a locking assembly. When the wind turbine blade needs to be fixed, the tooling arm is restricted in movement by the path rod, and then the tooling arm opens along the track of the oblique seven-shaped placement groove on the tooling arm. The hook part of the tooling arm fits the inner diameter of the blade to achieve automatic two-way fixation, thereby simplifying the welding operation steps of the wind turbine blade.

[0019] The present invention provides a touch assembly, and with the cooperation of the connecting block and the touch block, when the wind turbine blade is fixed, the movement distance of the touch plate can enter the interior of the connecting plate, and then the connecting block can drive the touch block to rotate when it rotates, and the touch block can rotate when it fits with the connecting block, thereby realizing automatic fixation and automatic stress elimination and automatic stress release, thereby improving the convenience of use.

[0020] The present invention provides a locking assembly. When the welded wind turbine blade needs to be taken out, the functional column moves linearly to drive the limit column to linearly pull the tooling arm from an open state to a contracted state, and then the tooling arm releases the fixation of the wind turbine blade, thereby achieving automatic release and improving production efficiency.

When the striking hammer 41 moves to a position away from the blocking ball 37, the stretched tension spring 43 rebounds and drives the striking hammer 41 to reset, and then the oscillation disk 38 rotates to form a state of cyclic impact and vibration.

[0045] Working principle:

[0046] The first step, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, when the wind turbine blade needs to be processed and welded, the wind turbine blade is placed on the side of the tooling tube 1 away from the carrying tube 12, and then the functional column 10 moves toward the position close to the blocking ring 11. The functional column 10 drives the connecting tube 8 to move when it moves, and the connecting tube 8 drives the connecting piece 7 to move when it moves. The connecting piece 7 drives the limiting column 9 to move when it moves, and the limiting column 9 drags the tooling arm 6 toward the position of the blocking ring 11 when it moves. The tooling arm 6 is blocked by the path rod 5 when it moves. When it moves, the tooling arm 6 opens in the shape of an oblique seven-character according to the tooling arm 6 placement slot. When it opens, the tooling arm 6 fits toward the inner diameter of the wind turbine blade, and the hook part of the tooling arm 6 fixes the inner ring of the wind turbine blade.

[0047] The second step is Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, when it is necessary to drive the functional column 10 to move toward the position of the blocking ring 11, the first motor 14 is started, and then the first motor 14 drives the first double-cone column 15 to rotate. When the first double-cone column 15 rotates, it drives the gear 16 to rotate. When the gear 16 rotates, it drives the placement cylinder 17 to move toward the inside of the bearing cylinder 12 through a plurality of tooth blocks 18. When the placement cylinder 17 moves, it drives the functional column 10 to move toward the position of the blocking ring 11. When it is necessary to release the fixation of the wind turbine blade, the first double-cone column 15 drives the gear 16 to rotate in the opposite direction. When the gear 16 rotates in the opposite direction, it drives the placement cylinder 17 to reset through the tooth blocks 18. When the placement cylinder 17 resets, it drives the functional column 10 to reset.

[0048] The third step, such as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, when the first double-cone column 15 rotates, the conical teeth on the first double-cone column 15 drive the single-cone column 24 to rotate. The single-cone column 24 drives the fan disc 28 to rotate. The fan disc 28 draws air from the outside of the carrier cylinder 12 into the dust removal cylinder 25 along the air inlet pipe 27. The air inside the dust removal cylinder 25 is blown toward the fixed wind turbine blades by the rotation of the fan disc 28. Then, the blown air driven by the rotation of the fan disc 28 cleans the floating dust and impurities on the wind turbine blades.

[0049] The fourth step is as follows Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 10As shown, when the wind turbine blade welding requires stress relief, the functional column 10 enters the interior of the connecting block 35 when it moves, and then the connecting block 35 fits with the touch block 30 on the functional column 10, and the second motor 32 is started. The second motor 32 drives the transmission column 33 to rotate, and the transmission column 33 drives the connecting plate 34 to rotate when it rotates. The connecting plate 34 drives the connecting block 35 to rotate when it rotates. The connecting block 35 drives the touch block 30 to rotate when it rotates. The touch block 30 drives the touch plate 29 to rotate when it rotates. The touch plate 29 drives the functional column 10 to rotate when it rotates. The functional column 10 drives the placement ring 19 to rotate when it rotates. The placement ring 19 drives the rotation column 20 to rotate along the annular groove of the placement cylinder 17 when it rotates.

[0050] Step 5: Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, when the functional column 10 enters the interior of the connecting block 35, the functional column 10 drives the oscillation disk 38 to correspond to the position of the groove ring 36 on the top of the blocking ring 11. When the functional column 10 rotates, the functional column 10 drives the oscillation disk 38 to rotate. When the oscillation disk 38 rotates, it drives the oscillation cylinder 39 to rotate. When the oscillation cylinder 39 rotates, it drives the limit ring 40 to rotate. The rotation of the limit ring 40 drives the percussion hammer 41 to rotate. When the percussion hammer 41 rotates, it drives the telescopic ball 42 to rotate through the collision column 44. Then, when the telescopic ball 42 rotates, When it rotates to the position corresponding to the blocking ball 37, the blocking ball 37 squeezes the telescopic ball 42 and moves toward the inside of the oscillation tube 39. The telescopic ball 42 drives the impact column 44 to move when it moves, and then the impact column 44 drives the striking hammer 41 to hit the oscillation tube 39 when it moves, and the striking hammer 41 drives the tension spring 43 to stretch when it moves. When the striking hammer 41 moves to a position away from the blocking ball 37, the stretched tension spring 43 rebounds and drives the striking hammer 41 to reset, and then the oscillation disk 38 rotates to form a state of cyclic impact and vibration.
