DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 13The present invention provides a technical solution: a device for correcting the shaft of a fan blade riveted into the fan blade, comprising a base 1, a positioning assembly 10 and a correction assembly 12, wherein the top of the base 1 is fixedly connected with a column 2, the column 2 is fixedly connected with a support plate 3, the support plate 3 is fixedly connected with a first telescopic rod 4, the telescopic end of the first telescopic rod 4 is fixedly connected with a fixed sleeve 5, the end of the fixed sleeve 5 is fixedly connected with an upper riveting module 6, the top of the base 1 is also fixedly connected with a fixed disk 7, the fixed disk 7 is fixedly connected with a storage column 8, and the axis of the storage column 8 is fixedly connected with an axis tube 9 for inserting the main shaft; the positioning assembly 10 comprises a plurality of groups of positioning pieces 11 slidably connected to the fixed disk 7, and the positioning assembly 10 completes the extrusion of the fan blade by moving the plurality of groups of positioning pieces 11, so that the fan blade It is coaxial with the upper riveting module 6 to complete the positioning of the fan blade; the correction component 12 is arranged in cooperation with the positioning component 10 and the upper riveting module 6. After the upper riveting module 6 detects that the fan blade is in a tilted state, the correction component 12 causes multiple groups of positioning pieces 11 to move up to correct the fan blade through the action of the correction component 12; the upper riveting module 6 includes an upper riveting block 13 fixedly connected to the fixed sleeve 5, and two groups of linear bearing columns 16 and two groups of equal-height bolts 14 are slidably connected to the upper riveting block 13. The ends of the linear bearing columns 16 and the equal-height bolts 14 are fixedly connected with a correction plate 15, and the top of the correction plate 15 is fixedly connected with a reset spring 17 sleeved on the outer side of the linear bearing column 16, and multiple groups of circularly arranged pressure sensors 18 are installed in the correction plate 15.

[0032] In this solution, during the process of riveting the fan blade into the shaft, the fan blade is placed at the end of the storage column 8, and then the main shaft is inserted into the axial position of the fan blade. At this time, the main shaft will enter the inside of the shaft tube 9, and then the positioning assembly 10 causes multiple groups of positioning pieces 11 to move toward the axis at the same time. The fan blade is positioned by the positioning piece 11 so that the fan blade is coaxial with the upper riveting module 6, and then the upper riveting module 6 is moved down to fit the fan blade by the first telescopic rod 4. At this time, the multiple groups of pressure sensors 18 in the upper riveting module 6 will detect pressure information. When the pressures detected by the multiple groups of sensors are inconsistent, it means that the fan blade is tilted and not consistent with the upper riveting module 6. The upper riveting module 6 is fitted, and the fan blade is corrected by the action of the correction component 12, so that the fan blade fits the upper riveting module 6. When the data of multiple groups of pressure sensors 18 displayed on the display screen are consistent or within a certain error range, the correction is completed at this time, and then the first telescopic rod 4 is controlled again to drive the upper riveting module 6 to move downward. During this process, the correction plate 15 will not continue to move after fitting with the fan blade. Therefore, the upper riveting block 13 is driven downward by the action of the first telescopic rod 4, and there is relative movement between the upper riveting block 13 and the correction plate 15. The riveting work between the fan blade and the main shaft is completed by the downward movement of the upper riveting plate.

[0033] In this solution, after the riveting is completed, the first telescopic rod 4 retracts and resets, and at this time, the upper riveting block 13 and the correction plate 15 are reset by the action of the reset spring 17.

[0034] The positioning assembly 10 includes a plurality of sliding blocks 19 slidably connected to the base 1 and the fixed plate 7, the top of the sliding block 19 is fixedly connected to a moving block 20, the moving block 20 is connected to a connecting piece 21, and the plurality of connecting pieces 21 are respectively connected to the plurality of positioning pieces 11, and the bottom of the sliding block 19 is fixedly connected to a threaded block 22 installed inside the base 1, the threaded block 22 is threadedly connected to a threaded rod 23 rotatably connected to the base 1, and the end of the threaded rod 23 is connected to a rotating piece 24 installed inside the base 1; the connecting piece 21 includes a movable block 26 slidably connected to the moving block 20, the movable block 26 is fixedly connected to the rotating piece 24 installed inside the base 1 The moving block 20 is fixedly connected to a first spring 27, and the movable block 26 is slidably connected to a sliding column 28 fixedly connected to the positioning piece 11. The outer side surface of the sliding column 28 is sleeved with a second spring 29, and the two ends of the second spring 29 are respectively fixedly connected to the positioning piece 11 and the movable block 26; the rotating member 24 includes a motor 30 fixed to the inside of the base 1, and the output end of the motor 30 is fixedly connected to a rotating plate 31, and the rotating plate 31 is fixedly connected to a gear ring 32, and the outer side surface of the gear ring 32 is meshedly connected to multiple groups of flat gears 33, and the multiple groups of flat gears 33 are respectively fixedly connected to the multiple groups of threaded rods 23, so as to drive the multiple groups of threaded rods 23 to rotate simultaneously.

[0035] In the present solution, during the positioning of the fan blade, the rotating plate 31 is driven to rotate by starting the motor 30, and the rotating action of the rotating plate 31 drives the gear ring 32 to rotate, thereby driving the flat gear 33 to rotate, and the rotation of the flat gear 33 drives the threaded rod 23 to rotate. During the rotation of the threaded rod 23, the threaded block 22 will be driven to move, and the movement of the threaded block 22 causes the sliding block 19 to drive the moving block 20 to move. During the movement of the moving block 20, the positioning piece 11 will be pushed to move by the action of the movable block 26, the sliding column 28 and the second spring 29. Therefore, when the motor 30 is started, multiple groups of positioning pieces 11 will all move to the axis center of the fixed plate at the same time. When all the positioning pieces 11 are in contact with the fan blade, the fan blade is positioned by the extrusion of the positioning piece 11, so that the fan blade is coaxial with the correction plate 15 and the upper riveted block 13.

[0036] In this solution, a sliding column 28 and a second spring 29 are arranged between the positioning piece 11 and the moving block 20. Therefore, during the extrusion process, the positioning piece 11 will compress the second spring 29 to avoid the rigid extrusion of the fan blade by the positioning piece 11, which is beneficial to protecting the fan blade and avoiding deformation of the fan blade due to excessive extrusion force.

[0037] The correction assembly 12 includes a plurality of push rods 34 slidably connected to the base 1, and the plurality of push rods 34 are respectively fixedly installed on the bottom ends of the plurality of positioning pieces 11, and the push rods 34 are fixedly connected to the lift rods 35, and the ends of the lift rods 35 are fixedly connected to lift blocks 36, and the outer side of the lift block 36 is sleeved with a sleeve 37, and the outer side of the sleeve 37 is fixedly connected to a fixing ring 38, and the fixing ring 38 is fixedly connected to a connecting rod 39 fixedly connected to the threaded block 22, and the end of the sleeve 37 is connected to a pressure control member 40 for controlling the internal pressure of the sleeve 37. It is convenient to correct the tilted fan blades; the pressure control component 40 includes a second telescopic rod 43 fixed inside the base 1, and the telescopic end of the second telescopic rod 43 is fixedly connected to a piston plate 42, and the outer side surface of the piston plate 42 is sleeved with a pressure control tube 41, and the end of the pressure control tube 41 is connected to a connecting tube 44, and the end of the connecting tube 44 is connected to a shunt tube 45, and the shunt tube 45 is connected to multiple groups of connecting hoses 46, and the multiple groups of connecting hoses 46 are respectively connected to the multiple groups of sleeves 37, which are used to control the air pressure inside the sleeve 37, thereby facilitating the control of the lifting and lowering of the lifting block 36.

[0038] In this solution, after positioning is completed, when the pressure sensor 18 detects that the fan blade is tilted, the second telescopic rod 43 is started at this time. The start of the second telescopic rod 43 will drive the piston plate 42 to move. The movement of the piston plate 42 squeezes the gas inside the pressure control tube 41 into the connecting tube 44, and the gas is squeezed into the multiple sets of sleeves 37 through the action of the shunt tube 45 and the connecting hose 46, thereby increasing the air pressure inside the sleeve 37. Therefore, the lifting block 36 inside the sleeve 37 will move upward due to the action of the air pressure, and the lifting rod 35 is moved upward by the upward movement of the lifting block 36, thereby driving the push rod 34 to move upward, and the positioning plate 11 is moved upward by the upward movement of the push rod 34, and the blade is pushed to move by the upward movement of the positioning plate 11. During the process, since the top of the fan blade is squeezed by the correction plate 15, when the fan blade is tilted, there is a gap between the correction plate 15 and the fan blade, and only the positioning piece 11 at the bottom of the gap will rise due to the action of air pressure, while the part that fits the correction plate 15 has no space to rise, and thus the positioning piece 11 will not move. The positioning piece 11 is moved upward by the action of air pressure and the rising distances of multiple groups of positioning pieces 11 are not equal. The fan blade is squeezed by multiple groups of positioning pieces 11 with different upward moving distances, so that the fan blade is squeezed and fits the correction plate 15, thereby ensuring the flatness of the fan blade, that is, it is equivalent to supporting the inclined bottom end of the fan blade through the action of multiple groups of positioning pieces 11 to maintain the balance of the fan blade, thereby completing the correction work of the fan blade.

[0039] A fixing assembly 25 for fixing the main shaft is installed inside the multiple groups of threaded rods 23, and the fixing assembly 25 includes multiple groups of fixing rods 49 fixed inside the base 1, and the multiple groups of fixing rods 49 are arranged in a circle on the outer side of the shaft tube 9, and the ends of the fixing rods 49 are fixedly connected to the limiting ring 48, and the limiting ring 48 is slidably connected to the extrusion rod 47, and the end of the extrusion rod 47 is connected to a pressure piece 50 for positioning and fixing the main shaft; the pressure piece 50 includes a threaded tube 51 fixed inside the threaded rod 23, and the threaded tube 51 is threadedly connected to a threaded column 52 slidably connected to the extrusion rod 47, and the threaded column 52 is fixedly connected to a third spring 53 fixedly connected to the extrusion rod 47, and the extrusion rod 47 is pressurized by the pressurized effect, so that the extrusion rod 47 squeezes the main shaft.

[0040] In this solution, during the rotation of the threaded rod 23, the threaded tube 51 inside the threaded rod 23 will be driven to rotate. The threaded tube 51 has a threaded column 52 connected to the inner thread, and the end of the threaded column 52 is slidably connected to the limit ring 48 through the extrusion rod 47. Therefore, during the rotation of the threaded tube 51, the threaded column 52 and the third spring 53 will drive the extrusion rod 47 to move forward. During the forward movement, multiple groups of extrusion rods 47 will squeeze the main shaft extending into the shaft tube 9. After the extrusion rod 47 contacts the main shaft, the threaded column 52 continues to move forward and pressurizes the extrusion column by squeezing the third spring 53, thereby ensuring the stability of the main shaft, keeping the main shaft vertical and coaxial with the upper riveting block 13, and improving the installation accuracy.

[0041] Furthermore, the end of the extrusion rod 47 is arranged in an arc shape and an anti-skid pad is installed on the end, which is conducive to the end of the extrusion rod 47 to fit the main shaft more closely, and the anti-skid pad can play an anti-skid and protective role.

[0042] Working principle: in the process of riveting the fan blade into the shaft, the fan blade is placed at the end of the storage column 8, and then the main shaft is inserted into the axial position of the fan blade. At this time, the main shaft will enter the shaft tube 9, and the rotating plate 31 will be driven to rotate by the start of the motor 30, and the gear ring 32 will be driven to rotate by the rotation of the rotating plate 31, and then the flat gear 33 will be driven to rotate, and the threaded rod 23 will be driven to rotate by the rotation of the flat gear 33. In the process of the rotation of the threaded rod 23, the threaded block 22 will be driven to move, and the movement of the threaded block 22 will make the sliding block 19 drive the moving block 20 to move. In the process of the moving block 20 moving, the movable block 26, the sliding column 28 and the second spring 29 will push the positioning piece 11 to move, so that when the motor 30 is started, multiple groups of positioning pieces 11 will all move toward the axis position of the fixed plate at the same time. When the positioning pieces 11 are all in contact with the fan blades, the fan blades are positioned by the squeezing effect of the positioning pieces 11, so that the fan blades are in a coaxial state with the correction plate 15 and the upper riveted block 13. Then the first telescopic rod 4 is started. Through the action of the first telescopic rod 4, the fixed sleeve 5 drives the upper riveted block 13 and the correction plate 15 to move downward to squeeze the blades. At this time, the pressure sensor 18 inside the correction plate 15 will detect the pressure information. When the pressures detected by multiple groups of sensors are inconsistent, it means that the fan blades are tilted and not in contact with the upper riveted module 6. At this time, the second telescopic rod 43 is started. The start of the second telescopic rod 43 will drive the piston plate 42 to move. The movement of the piston plate 42 will release the gas inside the pressure control tube 41. The gas is squeezed into the inside of the connecting pipe 44, and the gas is squeezed into the inside of the multiple sets of sleeves 37 through the action of the shunt pipe 45 and the connecting hose 46, thereby increasing the gas pressure inside the sleeve 37. Therefore, the lifting block 36 inside the sleeve 37 will move upward due to the action of the gas pressure, and the upward movement of the lifting block 36 drives the lifting rod 35 to move upward, thereby driving the top rod 34 to move upward, and the positioning piece 11 is driven to move upward by the upward movement of the top rod 34. The upward movement of the positioning piece 11 pushes the blade to move. In this process, since the top of the fan blade is squeezed by the correction plate 15, when the fan blade is tilted, there is a gap between the correction plate 15 and the fan blade. Only the positioning piece 11 at the bottom of the gap part will rise due to the action of the gas pressure, while the part that fits the correction plate 15 has no space to rise due to the positioning piece 11. Then the positioning piece 11 will not move, and the positioning piece 11 is moved upward by the action of air pressure, and the rising distances of the multiple groups of positioning pieces 11 are unequal. The fan blades are squeezed by the multiple groups of positioning pieces 11 with unequal upward movement distances, so that the fan blades are squeezed and fit the correction plate 15, thereby ensuring the flatness of the fan blades, that is, it is equivalent to supporting the inclined bottom end of the fan blades through the action of the multiple groups of positioning pieces 11 to maintain the balance of the fan blades, thereby completing the correction of the fan blades. At this time, the data of the multiple groups of pressure sensors 18 can be displayed on the display screen to determine whether the correction is completed. When the data of the multiple groups of pressure sensors 18 are consistent or within the allowable error range, it means that the correction is completed. After the positioning and correction of the fan blades are all completed, the first telescopic rod 4 is controlled again to drive the upper riveting module 6 to move downward.During this process, the correction plate 15 will not move further after being attached to the fan blade, so the upper riveting block 13 is driven downward by the first telescopic rod 4, and there is relative movement between the upper riveting block 13 and the correction plate 15, and the riveting work between the fan blade and the main shaft is completed by the downward movement of the upper riveting plate.

[0043] In this solution, after riveting is completed, the equipment can be reset by reversing the motor 30 and reversing the first telescopic rod 4 and the second telescopic rod 43, so as to facilitate operation of the next group of fan blades. Its working principle is roughly the same as the above working principle, and will not be elaborated here.
