Description

Technical Field

[0001] The utility model relates to the technical field of crossflow fan blade production, in particular to a crossflow fan blade beating correction device. Background Art

[0002] Crossflow impellers are core components for generating airflow in air conditioners, household fans, and other appliances. Blade runout affects airflow and operating noise. Blades are composed of multiple welded segments, and runout is affected by factors such as segment shape, weld positioning accuracy, and weld quality. Some finished products may have radial runout exceeding the specified value. Currently, one approach is to scrap these products, which increases production costs. Another approach is manual correction, but this is more cumbersome and requires more experience. Utility Model Content

[0003] The main purpose of the utility model is to provide a crossflow fan blade runout correction device, which aims to solve the technical problems in the prior art that if the product has a large diameter runout, it will be costly to directly scrap it, while manual correction is troublesome to operate.

[0004] To achieve the above-mentioned object, the present invention provides a crossflow fan blade runout correction device, comprising a frame, on which a rotating device, a radial runout detection device, a first heating device, and a downward pressure correction device are provided:

[0005] The rotating device includes a clamping rotating assembly and a supporting assembly spaced apart from each other. A crossflow blade can be placed between the clamping rotating assembly and the supporting assembly. The clamping rotating assembly is provided with a rotating clamping portion, which can clamp one end of the crossflow blade and drive the crossflow blade to rotate. The supporting assembly is provided with a supporting portion, which can support the other end of the crossflow blade.

[0006] The radial runout detection device includes a first radial runout detection element and an angle detection element. The angle detection element is connected to the rotating clamping portion and can detect the rotation angle of the rotating clamping portion. The first radial runout detection element is disposed beside the space between the rotating clamping portion and the supporting portion. The first radial runout detection element can move left and right relative to the frame. The first radial runout detection element can measure the radial runout of the crossflow blade at different positions in the left and right directions.

[0007] The first heating device includes a first hot air blowing member, which is arranged on the side of the space between the rotating clamping portion and the supporting portion. The first hot air blowing member can move in the left and right directions relative to the frame. The first hot air blowing member can blow hot air to heat the crossflow blades at different positions in the left and right directions.

[0008] The downward pressure correction device includes a downward pressure left and right drive unit, a downward pressure up and down drive unit and a downward pressure piece. The downward pressure left and right drive unit is arranged on the frame, the downward pressure left and right drive unit is transmission connected with the downward pressure up and down drive unit, the downward pressure up and down drive unit is transmission connected with the downward pressure piece, the downward pressure piece is arranged on the upper side of the space between the rotating clamping part and the supporting part, the downward pressure left and right drive unit can drive the downward pressure up and down drive unit and the downward pressure piece to move in the left and right directions, the downward pressure up and down drive unit can drive the downward pressure piece to move in the up and down directions, and the downward pressure piece can press the cross-flow fan blade downward at different positions in the left and right directions.

[0009] The crossflow fan blade to be corrected is placed between the clamping and rotating assembly and the supporting assembly. The rotating clamping part of the clamping and rotating assembly clamps one end of the crossflow fan blade, and the supporting part of the supporting assembly supports the other end of the crossflow fan blade. Then the rotating clamping part drives the crossflow fan blade to rotate. At the same time, the angle detection element detects the rotation angle of the crossflow fan blade. The first radial runout detection element moves left and right to different positions in the length direction of the crossflow fan blade, and detects the radial runout at different length positions to obtain the radial runout of the crossflow fan blade at different angles at different length positions, so as to obtain the blade correction position. Then the first hot air blowing member moves left and right to the left and right positions of the blade correction position. When the crossflow fan blade rotates, the first hot air blowing member blows hot air to heat the crossflow fan blade, so that the circle of the fan blade correction position is softened; then the rotating clamping part rotates the crossflow fan blade to turn the fan blade correction position to the upper side, and the left and right driving units drive the upper and lower driving units and the lower pressing member to move left and right to the upper side of the fan blade correction position. The upper and lower driving units drive the lower pressing member to press downward, and the lower pressing member is pressed on the fan blade correction position of the crossflow fan blade and presses downward. The crossflow fan blade is deformed by the downward pressure at the fan blade correction position, which can reduce the radial runout of the crossflow fan blade, thereby realizing automatic correction of the crossflow fan blade without manual correction and reducing the amount of scrapped finished products.

[0010] Preferably, the first heating device also includes a temperature detection element, which is arranged on the side of the space between the rotating clamping portion and the supporting portion. The temperature detection element can move in the left and right directions relative to the frame, and the temperature detection element can detect the temperature of the heating position on the cross-flow fan blade heated by the first hot air blowing member.

[0011] The correction effect is affected by the heating temperature of the cross-flow fan blades. When the first hot air blowing member heats the cross-flow fan blades, the temperature detection element can simultaneously detect the temperature of the heating position. When the temperature reaches the required heating temperature, the heating is stopped, which can make the heating temperature control more accurate and better control to achieve the required correction effect.

[0012] Preferably, the frame is also provided with a second radial runout detection device and a second heating device; the second radial runout detection device includes a second radial runout detection element, the supporting portion is used to support the end shaft of the cross-flow fan blade, the second radial runout detection element is arranged on the upper side of the supporting portion, and the second radial runout detection element is used to detect the radial runout of the end shaft of the cross-flow fan blade; the second heating device includes a second hot air blowing member, the second hot air blowing member is arranged on the side of the upper side of the supporting portion, and the second hot air blowing member can blow hot air to heat the connection position of the end shaft of the cross-flow fan blade and the end plate.

[0013] At the end shaft position of the crossflow impeller, the end shaft has excessive radial runout due to reasons such as the end shaft not being perpendicular to the end plate or the end plate being deformed. Therefore, when the cross-flow fan blade rotates, the second radial runout detection element can detect the radial runout of the end shaft, and the angle detection element detects the rotation angle of the cross-flow fan blade to obtain the radial runout of the end shaft at different angles, so that the end plate correction position can be obtained; then the second hot air blowing member heats and softens the connection position of the end shaft and the end plate of the cross-flow fan blade and the end plate with hot air, and then the rotating clamping part rotates the cross-flow fan blade to rotate the end plate correction position to the upper side, and the left and right driving units drive the upper and lower driving units and the lower pressure member to move left and right to the upper side of the end plate correction position, and the upper and lower driving units drive the lower pressure member to press downward, and the lower pressure member is pressed on the end plate correction position of the end plate and presses downward, the end plate is subjected to downward pressure, and the end shaft is subjected to the upward supporting force of the supporting part, so that the connection position of the end shaft and the end plate is deformed and the verticality of the end shaft and the end plate is improved, which can reduce the radial runout of the end shaft, thereby realizing automatic correction of the end shaft and the end plate.

[0045] like Figures 1 to 12 As shown, a crossflow fan blade vibration correction device includes a frame 1, on which a rotating device, a radial vibration detection device, a first heating device and a downward pressure correction device 6 are provided.

[0046] The rotating device includes a clamping rotating assembly 2 and a supporting assembly 3 arranged at intervals on the left and right. The cross-flow fan blade 9 can be placed between the clamping rotating assembly 2 and the supporting assembly 3. The clamping rotating assembly 2 is provided with a rotating clamping portion 21, which can clamp one end of the cross-flow fan blade 9 and drive the cross-flow fan blade 9 to rotate. The supporting assembly 3 is provided with a supporting portion 31, which can support the other end of the cross-flow fan blade 9.

[0047] The radial runout detection device includes a first radial runout detection element 4 and an angle detection element. The angle detection element is connected to the rotating clamping portion 21 and can detect the rotation angle of the rotating clamping portion 21. The first radial runout detection element 4 is arranged on the side of the space between the rotating clamping portion 21 and the supporting portion 31. The first radial runout detection element 4 can move left and right relative to the frame 1. The first radial runout detection element 4 can measure the radial runout of the crossflow fan blade 9 at different positions in the left and right directions. Multiple detection positions are set at different positions along the length of the crossflow fan blade 9. The detection position used in this embodiment is the radial plate 91 of the crossflow fan blade 9. The radial plate 91 is an annular disc. Each middle section has a radial plate 91 and multiple blades on the radial plate 91. The radial runout of the outer periphery of the multiple radial plates 91 is first detected. The radial runout of each radial plate 91 includes the runout at different circumferential angles. The radial runout of the entire crossflow fan blade 9 can be obtained, providing a position for subsequent correction.

[0048] The first heating device includes a first hot air blowing member 51, which is arranged on the side of the space between the rotating clamping portion 21 and the supporting portion 31. The first hot air blowing member 51 can move in the left and right directions relative to the frame 1. The first hot air blowing member 51 can blow hot air to heat the crossflow fan blades 9 at different positions in the left and right directions, specifically heating the connection welding position between the radial plate 91 and the blade. Since the radial plate 91 and the blade are plastic parts, they will soften after being heated to a certain temperature. After softening, they can be deformed and corrected. After lowering the temperature, they will maintain the deformed shape. The first hot air blowing member 51 can be a hot air gun or other device that can deliver hot air. Furthermore, the first heating device also includes a heating drive unit 52. The first hot air blowing member 51 is transmission-connected to the heating drive unit 52. The heating drive unit 52 can drive the first hot air blowing member 51 to move closer to or away from the crossflow fan blades 9, and can be closer to the crossflow fan blades 9 during heating.

[0049] The downward pressure correction device 6 includes a downward pressure left and right drive unit 61, a downward pressure upper and lower drive unit 62 and a downward pressure piece 63. The downward pressure left and right drive unit 61 is arranged on the frame 1. In this embodiment, the downward pressure left and right drive unit 61 is arranged on the rear side of the clamping rotating component 2 and the supporting component 3. The downward pressure left and right drive unit 61 is transmission-connected with the downward pressure upper and lower drive unit 62. The downward pressure upper and lower drive unit 62 is transmission-connected with the downward pressure piece 63. The downward pressure piece 63 is arranged on the upper side of the space between the rotating clamping part 21 and the supporting part 31. The downward pressure left and right drive unit 61 can drive the downward pressure upper and lower drive unit 62 and the downward pressure piece 63 to move in the left and right directions. The downward pressure upper and lower drive unit 62 can drive the downward pressure piece 63 to move in the up and down directions. The downward pressure piece 63 can press the cross-flow blade 9 downward at different positions in the left and right directions. The specific downward pressure action position is the position of the radial plate 91. The left-right downward pressure drive unit 61 can be a motion module such as a screw, a gear rack, or a synchronous wheel and a synchronous belt. The left-right downward pressure drive unit 61 includes a left-right movable seat 611 capable of left-right movement. The up-down downward pressure drive unit 62 and the down-pressing member 63 are disposed on the left-right movable seat 611. The up-down downward pressure drive unit 62 can be a motion module such as a cylinder, a screw, a gear rack, or a synchronous wheel and a synchronous belt. The downward pressure stroke of the up-down downward pressure drive unit 62 is adjustable, thereby adjusting the degree of downward pressure on the crossflow blades 9.

[0050] The crossflow fan blade 9 to be corrected is placed between the clamping rotation component 2 and the supporting component 3, the rotating clamping part 21 of the clamping rotation component 2 clamps one end of the crossflow fan blade 9, and the supporting part 31 of the supporting component 3 supports the other end of the crossflow fan blade 9. Then the rotating clamping part 21 drives the crossflow fan blade 9 to rotate, and at the same time, the angle detection element detects the rotation angle of the crossflow fan blade 9. The first radial runout detection element 4 moves left and right to different positions in the length direction of the crossflow fan blade 9, that is, the positions of multiple radial plates 91, and detects the radial runout at different length positions, that is, the positions of multiple radial plates 91, to obtain the radial runout of the crossflow fan blade 9 at different angles at different length positions, so that the fan blade correction position can be obtained. For example, the fan blade correction position can be the corresponding angular position of the corresponding radial plate 91 with the largest radial runout, with reference to FIG. Figure 11 The dotted line is a schematic diagram of the deformation of the crossflow fan blade 9. Pressing down at the position where the radial runout is the largest, that is, the position where the bending deformation is the largest, can straighten the crossflow fan blade 9 as a whole and reduce the runout.

[0051] Then the first hot air blowing member 51 moves left and right to the left and right positions of the fan blade correction position. While the crossflow fan blade 9 rotates, the first hot air blowing member 51 blows hot air to heat the crossflow fan blade 9, so that the circle where the fan blade correction position is located is softened; then the rotating clamping part 21 rotates the crossflow fan blade 9 to turn the fan blade correction position to the upper side, and the downward pressing left and right driving units 61 drive the downward pressing upper and lower driving units 62 and the downward pressing member 63 to move left and right to the upper side of the fan blade correction position, and the downward pressing upper and lower driving units 62 drive the downward pressing member 63 to press downward, and the downward pressing member 63 is pressed on the fan blade correction position of the crossflow fan blade 9 and pressed downward for a certain time. The two ends of the crossflow fan blade 9 are supported by the rotating clamping part 21 and the supporting part 31, and the middle part of the crossflow fan blade 9 is deformed by the downward pressure at the fan blade correction position, which can reduce the radial runout of the crossflow fan blade 9, thereby realizing automatic correction of the crossflow fan blade 9, without the need for manual correction, and reducing the amount of scrapped finished products.

[0052] After the pressing member 63 is pressed down for correction, the first radial runout detection element 4 can be used to detect whether the overall radial runout of the crossflow blade 9 is within the standard value. If it does not meet the standard value, it can be pressed down again for correction at the new blade correction position.

[0053] In some specific embodiments, the first heating device also includes a temperature detection element 53, which is arranged on the side of the space between the rotating clamping portion 21 and the supporting portion 31. The temperature detection element 53 can move in the left and right directions relative to the frame 1. The temperature detection element 53 can detect the temperature of the heating position on the cross-flow fan blade 9 heated by the first hot air blowing member 51.

[0054] The correction effect is affected by the heating temperature of the cross-flow fan blade 9. When the first hot air blowing member 51 heats the cross-flow fan blade 9, the temperature detection element 53 can simultaneously detect the temperature of the heating position. When the temperature reaches the required heating temperature, the heating is stopped, which can make the heating temperature control more accurate and better control to achieve the required correction effect.

[0055] In some specific embodiments, referring to Figure 4 and Figure 5 The frame 1 is also provided with a second radial runout detection device and a second heating device; the second radial runout detection device includes a second radial runout detection element 71, the supporting portion 31 is used to support the end shaft 92 of the crossflow fan blade 9, the second radial runout detection element 71 is provided on the upper side of the supporting portion 31, and the second radial runout detection element 71 is used to detect the radial runout of the end shaft 92 of the crossflow fan blade 9; the second heating device includes a second hot air blowing member 72, the second hot air blowing member 72 is provided on the side of the upper side of the supporting portion 31, and the second hot air blowing member 72 can blow hot air to heat the connection position between the end shaft 92 of the crossflow fan blade 9 and the end plate 94.

[0056] At the end shaft 92 of the crossflow fan blade 9, the end shaft has excessive radial runout due to reasons such as the end shaft not being perpendicular to the end plate or the end plate being deformed. Therefore, when the crossflow fan blade 9 rotates, the second radial runout detection element 71 can detect the radial runout of the end shaft 92, while the angle detection element detects the rotation angle of the crossflow fan blade 9 to obtain the radial runout of the end shaft 92 at different angles, thereby obtaining the end plate correction position. For example, the end plate correction position can be the angle at which the end shaft 92 is tilted upward from away from the end plate 94 to approach the end plate 94, as shown in FIG. Figure 12 .

[0057] Then, the crossflow blades are driven to rotate, while the second hot air blowing member 72 heats and softens the connection between the end shaft 92 and the end plate 94 of the crossflow blade 9 and the end plate 94 by blowing hot air circumferentially. Then, the rotating clamping portion 21 rotates the crossflow blade 9 to rotate the end plate correction position to the upper side. The downward pressing left and right drive unit 61 drives the downward pressing upper and lower drive units 62 and the lower pressing member 63 to move left and right to the upper side of the end plate correction position. The downward pressing upper and lower drive units 62 drive the lower pressing member 63 to press downward. The lower pressing member 63 presses on the end plate correction position of the end plate 94 and presses downward. The end plate 94 is subjected to downward pressure, and the end shaft 92 is supported by the upward support of the support portion 31, causing the connection between the end shaft 92 and the end plate 94 to deform, thereby improving the verticality of the end shaft 92 and the end plate 94, reducing the radial runout of the end shaft 92, and thus achieving automatic correction of the end shaft 92 and the end plate 94. The second hot air blowing member 72 can be a heat gun or other device that can deliver hot air.

[0058] In some specific embodiments, the first radial runout detection element 4 is a contactless distance measuring sensor, the second radial runout detection element 71 is a contact runout sensor, and the second radial runout detection device also includes a second radial runout lifting drive unit 711, which is transmission-connected to the second radial runout detection element 71. The second radial runout lifting drive unit 711 can drive the second radial runout detection element 71 to move in the up and down directions to move away from or closer to the pressing end shaft 92.

[0059] A contactless distance measuring sensor is used to measure the outer periphery of the crossflow impeller 9. The difference between the detected distance and the standard distance is the radial runout. Non-contact distance measurement avoids damage to the product and improves detection accuracy. The contactless distance measuring sensor can be a laser distance measuring sensor. Since the end shaft 92 is made of metal, non-contact distance measurement is inaccurate, so a contact runout sensor is used. During detection, the second radial runout lifting drive unit 711 can drive the contact runout sensor to press against the end shaft 92 for detection. The second radial runout lifting drive unit 711 can be a cylinder. The contact runout sensor has a detection contact, and the detection contact contacts the end shaft 92 to detect the runout.

[0060] In some specific embodiments, the second radial runout detection element 71 is in transmission connection with the downward-pressing left-right drive unit 61, capable of driving the second radial runout detection device in left-right motion. The second radial runout detection element 71 can be mounted on the left-right motion seat 611, tracing the downward-pressing up-and-down drive unit 62 and the downward-pressing member 63 in left-right motion. This can simplify the structure of the support portion 31 and increase space. In other embodiments, the second radial runout detection element 71 can also be positioned on one side of the support portion 31.

[0061] In some specific embodiments, the first radial runout detection element 4 and the first hot air blowing element 51 are both in transmission connection with a downward-pressing left-right drive unit 61, which can drive the first radial runout detection element 4 and the first hot air blowing element 51 to move in the left-right direction. The first radial runout detection element 4 and the first hot air blowing element 51 can be disposed on a left-right motion seat 611. This can reduce the number of components required to drive the left-right motion of the first radial runout detection element 4 and the first hot air blowing element 51, thereby reducing costs and simplifying the structure. The temperature detection element 53 can also be driven to move left-right by the downward-pressing left-right drive unit 61.

[0062] In some specific embodiments, the lower side of the pressing member is an arc-shaped surface, which better matches the shape of the cross-flow fan blade and can also press down on the point with large fluctuation when there is a deviation in the angle detection.

[0063] In some specific embodiments, the crossflow blade vibration correction device further includes a preheating device 8, which is disposed at the lower side of the space between the rotating clamping portion 21 and the supporting portion 31. The preheating device 8 can preheat the crossflow blade 9 upward.

[0064] The preheating device 8 can preheat the entire crossflow blade 9 to a certain temperature without softening the crossflow blade 9. The first hot air blowing element 51 then heats the crossflow blade 9 to soften it. This can reduce the heating time of the first hot air blowing element 51, especially in low ambient temperatures, and improve the correction efficiency. The preheating device 8 can be heated by blowing hot air upward.

[0065] In some specific embodiments, referring to Figures 6 to 10 The clamping and rotating assembly 2 includes a first base 22, which is fixedly connected to the frame 1. The first base 22 is provided with an expansion shaft mechanism, which is provided with an insertion portion 23 that can radially expand or contract. The insertion portion 23 faces the supporting assembly 3.

A supporting portion 31 is provided on the third base 33 and is used to support the end shaft 92 of the other end of the crossflow blade 9.

[0067] The third base 33 is further provided with a pushing mechanism 35, which includes a pushing drive unit 351 and a pushing member 352. The pushing member 352 is provided beside the supporting portion 31 and away from the insertion portion 23. The pushing drive unit 351 is fixed to the third base 33 and is in transmission connection with the pushing member 352. The pushing drive unit 351 can drive the pushing member 352 toward or away from the insertion portion 23.

[0068] The rotating device also includes a lower supporting assembly 39, which includes a lower supporting drive unit 391 and a lower supporting member 392. The lower supporting drive unit 391 is connected to the frame 1, and the lower supporting member 392 is arranged on the lower side of the space between the rotating clamping portion 21 and the supporting portion 31. The lower supporting member 392 can support the lower side of the cross-flow fan blade 9. The lower supporting member 392 is transmission-connected to the lower supporting drive unit 391, and the lower supporting drive unit 391 can drive the lower supporting member 392 to move in the up and down directions to support the cross-flow fan blade 9 between the insertion portion 23 and the supporting portion 31 or downward away from the cross-flow fan blade 9.

[0069] When placing the crossflow fan blade 9 between the clamping rotating assembly 2 and the supporting assembly 3, the rotating clamping part 21 and the supporting part 31 are first separated from each other, and the lower supporting part 392 is in an upper position, and the crossflow fan blade 9 is placed on the lower supporting part 392. At this time, the two ends of the crossflow fan blade 9 are facing the insertion part 23 and the supporting part 31; the first moving driving unit 34 drives the third base 33, the supporting part 31 and the pushing mechanism 35 to move toward the side close to the clamping rotating assembly 2, and the pushing driving unit 351 drives the pushing member 352 to move toward the side close to the insertion part 23. During the movement of the third base 33, the pushing member 352 pushes the crossflow fan blade 9 toward the insertion part 23, so that the insertion part 23 Inserted into the end hole 93 at one end of the cross-flow fan blade 9, the supporting part 31 moves to the lower side of the end shaft 92 at the other end of the cross-flow fan blade 9, and then the push-in drive unit 351 drives the pushing part 352 to move to the side away from the insertion part 23 away from the cross-flow fan blade 9 to avoid affecting the rotation of the cross-flow fan blade 9, and the lower support drive unit 391 drives the lower support part 392 to descend away from the cross-flow fan blade 9, so that the middle part of the cross-flow fan blade 9 is suspended in the air, and the insertion part 23 can expand and clamp the cross-flow fan blade 9 in the end hole 93 of the cross-flow fan blade 9, and the rotation drive unit 24 can drive the insertion part 23 and the cross-flow fan blade 9 to rotate, thereby realizing the clamping and rotation of the cross-flow fan blade 9 by the clamping rotation component 2 and the supporting component 3.

[0070] Furthermore, an ejection mechanism 25 is provided on the first base 22, and the ejection mechanism 25 includes an ejection drive unit 251 and an ejection member 252. The ejection member 252 is arranged on the side of the insertion portion 23 and away from the supporting portion 31.

The ejection drive unit 251 can drive the ejection member 252 to approach or move away from the supporting portion 31.

[0071] When the correction is complete, the lower support drive unit 391 drives the lower support member 392 upward, and the first movable drive unit 34 drives the third base 33, the supporting portion 31, and the pushing mechanism 35 to move away from the clamping and rotating assembly 2. The insertion portion 23 contracts and releases the end hole 93. The ejection drive unit 251 drives the ejection member 252 to move toward the side closer to the supporting portion 31. The ejection member 252 pushes the crossflow blade 9 out of the insertion portion 23, and the crossflow blade 9 falls onto the lower support member 392. The ejection drive unit 251, the first movable drive unit 34, and the pushing drive unit 351 can be driven by a cylinder or other drive mechanism.

[0072] Furthermore, the expansion shaft mechanism includes an insertion shaft 26, an expansion block 27 and a telescopic shaft 28. The insertion shaft 26 is rotatably connected to the first base 22. The telescopic shaft 28 is arranged on the inner side of the insertion shaft 26 and is arranged parallel to the insertion shaft 26. The telescopic shaft 28 is axially slidably connected to the insertion shaft 26. The insertion shaft 26 is provided with a radially arranged slot. The expansion block 27 is slidably connected in the slot. The side of the insertion shaft 26 close to the supporting portion 31 is the insertion portion 23. The expansion block 27 is provided on the insertion portion 23. The first base 22 is also provided with an expansion shaft driving unit 29. The expansion shaft driving unit 29 is transmission-connected to the telescopic shaft 28. Then, the expansion shaft driving unit 29 can drive the telescopic shaft 28 to move axially. A first inclined surface 271 is provided on the expansion block 27, and a second inclined surface 281 is provided on the telescopic shaft 28 to match the first inclined surface 271. The telescopic shaft 28 and the expansion block 27 cooperate through the first inclined surface 271 and the second inclined surface 281, so that the axial movement of the telescopic shaft 28 can drive the expansion block 27 to move radially along the insertion shaft 26 to shrink or protrude from the insertion shaft 26. When the expansion block 27 protrudes from the insertion shaft 26, the end hole 93 of the cross-flow fan blade 9 can be clamped, and when the expansion block 27 shrinks, the cross-flow fan blade 9 can be loosened.

[0073] The rotation drive unit 24 can be a servo motor with an angle detection element. The rotation drive unit 24 and the insertion shaft 26 can be connected by a transmission structure such as a synchronous belt or gears. In other embodiments, the angle detection element can be an encoder. The expansion shaft drive unit 29 can be a drive mechanism such as a cylinder. The telescopic shaft 28 and the moving end of the expansion shaft drive unit 29 are relatively fixed axially. The telescopic shaft 28 is rotationally connected to the moving end of the expansion shaft drive unit 29. In this way, the rotation of the insertion shaft 26 and the telescopic shaft 28 does not affect the movement of the telescopic shaft 28 driven by the expansion shaft drive unit 29.

The first roller 311 and the second roller 312 are arranged front to back. The upper recessed position between the first roller 311 and the second roller 312 is the supporting portion 31 .

[0075] The recessed position on the upper side between the first roller 311 and the second roller 312 can support the end shaft 92 of the cross-flow blade 9. The gap between the first roller 311 and the second roller 312 is smaller than the diameter of the end shaft 92 of the cross-flow blade 9. When the cross-flow blade 9 rotates, the first roller 311 and the second roller 312 will rotate with the end shaft 92 of the cross-flow blade 9 to reduce the wear on the end shaft 92.

[0076] Furthermore, the second base 32 is slidably connected to the frame 1 along the left-right direction. A locking structure 38 is connected between the second base 32 and the frame 1 , and the locking structure 38 can lock the left-right position of the second base 32 on the frame 1 .

[0077] Specifically, the second base 32 can slide with the frame 1 via an adjustable guide rail 37. The second base 32 can be adjusted closer to or farther from the first base 22. The adjusted position of the second base 32 can be locked by a locking structure 38. In other words, the distance between the clamping rotation assembly 2 and the supporting assembly 3 can be adjusted to accommodate the clamping and correction of crossflow blades 9 of different lengths. The locking structure 38 can be locked using a screw or other structure.
