Description

Technical Field

[0001] This utility model relates to the field of cross-flow fan blade testing technology, and in particular to a positioning clamping and rotating device and a testing equipment. Background Technology

[0002] Cross-flow fan blades are widely used in air conditioners, household fans, and other equipment. During production, to ensure product quality, cross-flow fan blades need to be inspected. Currently, the method for clamping and rotating cross-flow fan blades during inspection often involves inserting an expansion shaft mechanism into the fan blade's feed hole and then tightening it. However, because the expansion shaft mechanism has a small expansion range, the dimensional matching requirements between the expansion shaft diameter and the feed hole diameter are high. This necessitates very high initial positioning accuracy for the cross-flow fan blade to insert into the feed hole. During automatic feeding, this can easily lead to situations where the mechanism cannot be inserted and clamped, causing machine stoppages requiring manual intervention or even product damage. Furthermore, a single-size expansion shaft mechanism cannot accommodate cross-flow fan blades with feed hole diameters of various sizes.

[0003] Furthermore, the current industry standard for visual inspection of cross-flow fan blades primarily relies on manual methods, where operators hold the products and inspect them one by one visually. This method is not only labor-intensive, costly, and inefficient, but also susceptible to subjective factors and visual fatigue, easily leading to missed inspections and misjudgments, making it difficult to meet the consistency and reliability requirements of large-scale production. Although some companies have attempted to use visual inspection systems to replace manual labor, capturing images with cameras and identifying defects, the inspection results are not ideal, and the inspection methods are complex. Utility Model Content

[0004] The main purpose of this utility model is to propose a positioning clamping and rotating device and a detection device, which aims to solve the technical problem that the existing method of clamping cross-flow fan blades requires high positioning accuracy of the cross-flow fan blades and is prone to failure to clamp the cross-flow fan blades.

[0005] To achieve the above objectives, this utility model proposes a positioning, clamping, and rotating device, including a clamping shaft assembly and a supporting assembly arranged at left and right intervals, wherein a placement space for placing a cross-flow fan blade is provided between the clamping shaft assembly and the supporting assembly. The clamping shaft assembly includes a first base, on which an end shaft clamp is provided. The end shaft clamp is capable of clamping the end shaft at the first end of the cross-flow fan blade. The first base is also provided with a clamp driving unit and a rotation driving unit. The clamp driving unit is induced to the end shaft clamp to drive the end shaft clamp to retract and clamp the end shaft or open and release the end shaft. The rotation driving unit is induced to the end shaft clamp to drive the end shaft clamp to rotate. The support assembly includes a second base, on which a second front idler roller and a second rear idler roller are rotatably connected. A second groove is provided between the second front idler roller and the second rear idler roller. The second front idler roller and the second rear idler roller are capable of supporting and positioning the outer periphery of the second end of the cross-flow fan blade located in the second groove.

[0006] The cross-flow fan blade to be tested is fed between the clamping shaft assembly and the support assembly. The end shaft of the cross-flow fan blade is clamped by the end shaft grippers. When the end shaft of the cross-flow fan blade is inserted into the inner side of the end shaft grippers, the gripper drive unit drives the end shaft grippers to retract, thus clamping the end shaft. Then, the rotation drive unit drives the end shaft grippers to rotate, thus rotating the cross-flow fan blade. When it is necessary to remove the cross-flow fan blade, the gripper drive unit drives the end shaft grippers to open, thus releasing the end shaft. The second groove between the second front roller and the second rear roller supports and positions the outer periphery of the second end of the cross-flow fan blade. The second front roller and the second rear roller rotate with the cross-flow fan blade, reducing wear. The rotation drive unit drives the end shaft grippers and the cross-flow fan blade to rotate, achieving the positioning, clamping, and rotation of the cross-flow fan blade.

[0007] This positioning, clamping, and rotating device clamps the end shaft of the cross-flow fan blade using a clamping shaft assembly. Compared to existing expansion shaft mechanisms, the end shaft grippers have a larger clamping range and are not limited by the size and shape of the stepper holes on the cross-flow fan blade. This allows it to accommodate larger initial positioning deviations of the cross-flow fan blade. The clamping shaft assembly more easily clamps the end shaft of the cross-flow fan blade, reducing the accuracy requirements for cross-flow fan blade positioning, increasing the success rate of clamping the cross-flow fan blade, reducing downtime for manual intervention and product damage, and adapting to the inspection of more different cross-flow fan blades.

[0008] Preferably, the positioning and clamping rotating device further includes a pushing mechanism and a pushing mechanism; The pushing mechanism includes a pushing drive unit and a pushing member. The pushing member is located on the side of the second tray away from the end shaft clamp. The pushing drive unit is connected to the pushing member in a transmission manner. The pushing drive unit can drive the pushing member to move in a direction close to or away from the end shaft clamp. When the pushing member is close to the end shaft clamp, it can push the end shaft of the cross-flow fan blade into the end shaft clamp. The ejection mechanism includes an ejection drive unit and an ejection member. The ejection member is located beside the end shaft clamp. The ejection drive unit is connected to the ejection member in a transmission manner. The ejection drive unit can drive the ejection member to move in a direction close to or away from the support component. When the ejection member is close to the support component, it can eject the end shaft of the cross-flow fan blade to the outside of the end shaft clamp.

[0009] When clamping the cross-flow fan blade, the second end of the cross-flow fan blade is placed in the second slot. The pushing mechanism pushes the end face of the second end of the cross-flow fan blade, pushing the end shaft of the cross-flow fan blade into the end shaft clamp, which then holds the end shaft. After inspection, the pushing mechanism pushes the end face of the first end of the cross-flow fan blade, pushing the end shaft of the cross-flow fan blade to the outside of the end shaft clamp, allowing the cross-flow fan blade to be removed. The overall structure and operation process are relatively simple.

[0010] Preferably, an outer limiting sleeve is rotatably connected to the first base. The end of the outer limiting sleeve near the supporting component is provided with a first contraction cone surface. The end shaft clamp is provided on the inner side of the outer limiting sleeve. The outer periphery of the end shaft clamp is provided with a second contraction cone surface. The first contraction cone surface and the second contraction cone surface are matched and configured. The end shaft clamp and the outer limiting sleeve are slidably connected in the left-right direction. The gripper drive unit is fixedly connected to the first base. The moving end of the gripper drive unit is provided with a drive shaft. The drive shaft is axially fixed to the moving end of the gripper drive unit and rotatably connected to the moving end of the gripper drive unit. The end shaft gripper is detachably connected to the drive shaft. The gripper drive unit can drive the end shaft gripper to move in a direction close to or away from the support component. When the end shaft gripper moves away from the support component, the first contraction cone surface and the second contraction cone surface slide relative to each other, causing the end shaft gripper to contract to grip the end shaft of the cross-flow fan blade. When the end shaft gripper approaches the support component, the end shaft gripper springs back and opens to release the end shaft of the cross-flow fan blade. The rotary drive unit is fixedly connected to the first base, and the rotary drive unit is drivenly connected to the outer limiting sleeve. The outer limiting sleeve is circumferentially fixed to the drive shaft.

[0011] When the end shaft is to be clamped, the gripper drive unit drives the drive shaft and the end shaft gripper to move away from the support mechanism. The first contraction cone surface of the outer limit sleeve compresses the second contraction cone surface on the outer periphery of the end shaft gripper, causing the end shaft gripper to contract and clamp the end shaft. The rotation drive unit then drives the outer limit sleeve, the end shaft gripper, and the cross-flow fan blade to rotate. Since the drive shaft is rotatably connected to the moving end of the gripper drive unit, the gripper drive unit will not rotate.

[0012] Preferably, the inner side of the end shaft gripper is provided with a protective sleeve for contacting the end shaft. When gripping the end shaft, the protective sleeve contacts the end shaft, protecting the end shaft from damage to its surface.

[0013] In another aspect, this utility model also proposes a testing device, which includes a frame on which the positioning, clamping, and rotating device is provided.

[0014] By adopting the above-mentioned positioning, clamping, and rotating device, it is easier to clamp the end shaft of the cross-flow fan blade, reduce the accuracy requirements for positioning the cross-flow fan blade, increase the success rate of clamping the cross-flow fan blade, and reduce downtime, manual intervention, and product damage.

[0015] Preferably, the detection device further includes a visual inspection device, which includes a detection camera, a coaxial light source, and a back-side light source. The coaxial light source and the back-side light source are arranged circumferentially along the placement space. The illumination direction of the coaxial light source and the illumination direction of the back-side light source are both facing the placement space. The detection camera is coaxially arranged with the coaxial light source and is located on the side of the coaxial light source away from the placement space.

[0016] Coaxial and back-side light sources are arranged circumferentially around the cross-flow fan blades to illuminate them, resulting in better lighting effects. The inspection camera then captures images of the cross-flow fan blades, improving inspection accuracy and enabling automatic visual inspection of the cross-flow fan blades with good image quality.

[0017] Preferably, the detection camera and the coaxial light source are positioned directly above the placement space, with the detection camera positioned above the coaxial light source and the rear-side light source positioned at the lower front or lower rear side of the placement space.

[0018] Preferably, the number of detection cameras is one, the frame is provided with a camera movement drive unit, the detection camera is located on the moving end of the camera movement drive unit, and the camera movement drive unit can drive the detection camera to move in the left and right direction to detect different axial positions of the cross-flow fan blades.

[0019] Preferably, the frame is further provided with a clamping shaft moving drive unit, which is connected to the first base in a transmission manner. The clamping shaft moving drive unit can drive the clamping shaft assembly to move closer to or away from the supporting assembly. The testing equipment also includes a receiving mechanism, which includes a receiving lifting drive unit and a receiving component. The receiving component is located on the lower side of the placement space. The receiving lifting drive unit is connected to the receiving component in a transmission manner. The receiving lifting drive unit can drive the receiving component to move in the up and down direction. When the receiving component moves upward, it can receive the cross-flow fan blades that detach from the clamping shaft assembly and the supporting assembly.

[0020] After the inspection is completed, the receiving mechanism's receiving lifting drive unit drives the receiving component to rise to the lower side near the cross-flow fan blade; the end shaft gripper releases the end shaft of the cross-flow fan blade, and after the end shaft is pushed out of the end shaft gripper, the clamping shaft moving drive unit drives the clamping shaft assembly away from the support assembly, leaving space for the cross-flow fan blade to move out of the support assembly; then, the pushing component of the pushing mechanism pushes the cross-flow fan blade to the side near the clamping shaft assembly, and the second end of the cross-flow fan blade leaves the support assembly, and the cross-flow fan blade falls onto the receiving component; then the receiving lifting drive unit drives the receiving component to move downward, removing the inspected cross-flow fan blade and unloading it, so that a new cross-flow fan blade to be inspected can be loaded and inspected.

[0021] Preferably, the testing equipment further includes a material drop plate, which is fixed on the frame and located on the lower side of the placement space and on the side of the receiving mechanism. The material drop plate is inclined up and down in the front-back direction, and the receiving component can be lower than the material drop plate when it moves downward so that the cross-flow fan blades fall on the material drop plate.

[0022] The receiving component supports the cross-flow fan blades as they move downwards. When the cross-flow fan blades fall onto the discharge plate, they remain on the discharge plate and then slide down the discharge plate at an angle to other positions. The material discharge structure is relatively simple.

[0023] Preferably, the support assembly further includes a support lifting drive unit, which is disposed on the frame, and the second base is disposed on the moving end of the support lifting drive unit, and the support lifting drive unit can drive the second base to move in the up and down direction; The number of receiving mechanisms is two, and the two receiving mechanisms are respectively located close to the clamping shaft assembly and the supporting assembly, with the receiving mechanism closest to the clamping shaft assembly being the first receiving mechanism; The first receiving mechanism further includes a receiving base, and the receiving lifting drive unit is disposed on the receiving base. The receiving base and the first base are slidably connected to the frame in the left-right direction. A position adjustment mechanism is provided between the receiving base and the frame. The position adjustment mechanism can adjust the left-right position of the receiving base on the frame. The clamping shaft moving drive unit is connected to the receiving base and the first base.

[0024] The lifting and supporting drive unit can adjust the height of the second base, which, in conjunction with the height of the end shaft gripper, can accommodate cross-flow fan blades of different diameters for inspection, thus improving versatility. The first receiving mechanism, the clamping shaft assembly, and the clamping shaft moving drive unit can be adjusted left and right to regulate the distance between themselves and the supporting assembly, thereby accommodating cross-flow fan blades of different lengths for inspection and improving versatility.

[0032] like Figures 1 to 6 As shown, a positioning, clamping and rotating device includes a clamping shaft assembly 1 and a supporting assembly 2 arranged at left and right intervals, and a placement space for placing a cross-flow fan blade 9 is provided between the clamping shaft assembly 1 and the supporting assembly 2.

[0033] The clamping shaft assembly 1 includes a first base 11, on which an end shaft clamping jaw 12 is provided. The end shaft clamping jaw 12 is capable of clamping the end shaft 91 at the first end of the cross-flow fan blade 9. The first base 11 is also provided with a clamping jaw driving unit 13 and a rotation driving unit 14. The clamping jaw driving unit 13 is connected to the end shaft clamping jaw 12 to drive the end shaft clamping jaw 12 to retract and clamp the end shaft 91 or to open and release the end shaft 91. The rotation driving unit 14 is connected to the end shaft clamping jaw 12 to drive the end shaft clamping jaw 12 to rotate.

[0034] The support assembly 2 includes a second base 21, on which a second front idler roller 22 and a second rear idler roller 23 are rotatably connected. A second groove is provided between the second front idler roller 22 and the second rear idler roller 23. The second front idler roller 22 and the second rear idler roller 23 can support and position the outer periphery of the second end of the cross-flow fan blade 9 located in the second groove.

[0035] The cross-flow fan blade 9 to be tested is fed between the clamping shaft assembly 1 and the support assembly 2. The end shaft 91 of the cross-flow fan blade 9 is clamped by the end shaft clamping jaw 12 to achieve clamping of the cross-flow fan blade 9. When the end shaft 91 of the cross-flow fan blade 9 is inserted into the inside of the end shaft clamping jaw 12, the clamping jaw drive unit 13 drives the end shaft clamping jaw 12 to retract and clamp the end shaft 91 of the cross-flow fan blade 9. Then, the rotation drive unit 14 drives the end shaft clamping jaw 12 to rotate and drive the cross-flow fan blade 9 to rotate. When it is necessary to remove the cross-flow fan blade 9, the clamping jaw drive unit 13 drives the end shaft clamping jaw 12 to open and release the end shaft 91 of the cross-flow fan blade 9. The second groove between the second front roller 22 and the second rear roller 23 can support and position the outer periphery of the second end of the cross-flow fan blade 9. The second front roller 22 and the second rear roller 23 can rotate with the cross-flow fan blade 9 to reduce wear. The rotation drive unit 14 drives the end shaft clamp 12 and the cross-flow fan blade 9 to rotate, thereby realizing the positioning, clamping and rotation of the cross-flow fan blade 9.

[0036] This positioning, clamping, and rotating device clamps the end shaft 91 of the cross-flow fan blade 9 using the clamping shaft assembly 1. Compared to existing expansion shaft mechanisms, the end shaft gripper 12 has a larger clamping range and is not limited by the size and shape of the stepper hole on the cross-flow fan blade. It can adapt to larger initial positioning deviations of the cross-flow fan blade 9. The clamping shaft assembly 1 can more easily clamp the end shaft 91 of the cross-flow fan blade 9, reducing the accuracy requirements for positioning the cross-flow fan blade 9, increasing the success rate of clamping the cross-flow fan blade 9, reducing downtime for manual intervention and product damage, and adapting to the inspection of more different cross-flow fan blades.

[0037] In some specific embodiments, the positioning and clamping rotating device further includes a pushing mechanism 3 and a pushing mechanism 4; The pushing mechanism 3 includes a pushing drive unit 31 and a pushing member 32. The pushing member 32 is located on the side of the second tray away from the end shaft clamp 12. The pushing drive unit 31 is connected to the pushing member 32 in a transmission manner. The pushing drive unit 31 can drive the pushing member 32 to move in a direction close to or away from the end shaft clamp 12. When the pushing member 32 is close to the end shaft clamp 12, it can push the end shaft 91 of the cross-flow fan blade 9 into the end shaft clamp 12. The ejection mechanism 4 includes an ejection drive unit 41 and an ejection member 42. The ejection member 42 is located on the side of the end shaft clamp 12. The ejection drive unit 41 is connected to the ejection member 42 in a transmission manner. The ejection drive unit 41 can drive the ejection member 42 to move in a direction close to or away from the support component 2. When the ejection member 42 is close to the support component 2, it can push the end shaft 91 of the cross-flow fan blade 9 to the outside of the end shaft clamp 12.

[0038] When clamping the cross-flow fan blade 9, the second end of the cross-flow fan blade 9 is placed in the second slot. The pushing member 32 of the pushing mechanism 3 can push the end face of the second end of the cross-flow fan blade 9, pushing the end shaft 91 of the cross-flow fan blade 9 into the end shaft clamp 12, and then the end shaft clamp 12 clamps the end shaft 91. After the inspection is completed, the pushing member 42 of the pushing mechanism 4 can push the end face of the first end of the cross-flow fan blade 9, pushing the end shaft 91 of the cross-flow fan blade 9 out to the outside of the end shaft clamp 12, and then the cross-flow fan blade 9 can be removed. The overall structure and operation process are relatively simple. The pushing drive unit 31 and the pushing drive unit 41 can be cylinders.

[0039] In some specific embodiments, reference is made to Figure 2 An outer limiting sleeve 15 is rotatably connected to the first base 11. The end of the outer limiting sleeve 15 near the support component 2 is provided with a first contraction cone surface 151. The end shaft clamp 12 is located on the inner side of the outer limiting sleeve 15. The outer periphery of the end shaft clamp 12 is provided with a second contraction cone surface 121. The first contraction cone surface 151 and the second contraction cone surface 121 are matched and configured. The end shaft clamp 12 and the outer limiting sleeve 15 are slidably connected in the left and right direction. The gripper drive unit 13 is fixedly connected to the first base 11. The moving end of the gripper drive unit 13 is provided with a drive shaft 16. The drive shaft 16 is axially fixed to the moving end of the gripper drive unit 13. The drive shaft 16 is rotatably connected to the moving end of the gripper drive unit 13. The end shaft gripper 12 is detachably connected to the drive shaft 16. The gripper drive unit 13 can drive the end shaft gripper 12 to move in the direction of approaching or moving away from the support component 2. When the end shaft gripper 12 moves away from the support component 2, the first contraction cone surface 151 and the second contraction cone surface 121 slide relative to each other to make the end shaft gripper 12 contract to grip the end shaft 91 of the cross-flow fan blade 9. When the end shaft gripper 12 approaches the support component 2, the end shaft gripper 12 rebounds and opens to release the end shaft 91 of the cross-flow fan blade 9. The rotary drive unit 14 is fixedly connected to the first base 11, and the rotary drive unit 14 is connected to the outer limiting sleeve 15 in a transmission manner. The outer limiting sleeve 15 is circumferentially fixed to the drive shaft 16.

[0040] When clamping the end shaft 91, the gripper drive unit 13 drives the drive shaft 16 and the end shaft gripper 12 to move away from the support mechanism. The first contraction cone surface 151 of the outer limiting sleeve 15 compresses the second contraction cone surface 121 on the outer periphery of the end shaft gripper 12. The end shaft gripper 12 has multiple circumferentially arranged clamping petals, causing the multiple clamping petals of the end shaft gripper 12 to contract inward and clamp the end shaft 91. The rotation drive unit 14 then drives the outer limiting sleeve 15, the end shaft gripper 12, and the cross-flow fan blade 9 to rotate. However, since the drive shaft 16 is rotatably connected to the moving end of the gripper drive unit 13, the gripper drive unit 13 will not rotate. The end shaft gripper 12 is detachably connected to the drive shaft 16. By replacing the end shaft gripper 12 with different inner hole sizes, it can accommodate more cross-flow fan blades 9 with different diameters of end shaft 91, thus improving its versatility. Specifically, the gripper drive unit 13 can be a cylinder, and the piston shaft of the cylinder is rotatably connected to the drive shaft 16 and axially fixed; the rotary drive unit 14 is a motor, and the motor is driven by the outer limit sleeve 15 through the synchronous pulley 17 and the synchronous belt module.

[0041] In some specific embodiments, the inner side of the end shaft gripper 12 is provided with a protective sleeve for contacting the end shaft 91. When gripping the end shaft, the protective sleeve contacts the end shaft, protecting the end shaft from damage to its surface.

[0042] On the other hand, refer to Figure 3 A testing device, comprising a frame 5, on which a positioning, clamping and rotating device is provided.

[0043] By employing the aforementioned positioning, clamping, and rotating device, the end shaft 91 of the cross-flow fan blade 9 can be clamped more easily, reducing the accuracy requirements for positioning the cross-flow fan blade 9, increasing the success rate of clamping the cross-flow fan blade 9, and reducing downtime for manual intervention and product damage. The testing equipment can be used for visual inspection or runout detection, etc.

[0044] In some specific embodiments, reference is made to Figure 6 The inspection equipment also includes a visual inspection device, which includes an inspection camera 61, a coaxial light source 62, and a back-side light source 63. The coaxial light source 62 and the back-side light source 63 are arranged circumferentially along the placement space. The illumination direction of the coaxial light source 62 and the illumination direction of the back-side light source 63 are both facing the placement space. The inspection camera 61 is coaxially set with the coaxial light source 62 and is located on the side of the coaxial light source 62 away from the placement space.

[0045] The coaxial light source 62 and the back-side light source 63 are arranged around the cross-flow fan blade 9 and illuminate the cross-flow fan blade 9, which can obtain a good lighting effect. The detection camera 61 takes pictures of the cross-flow fan blade 9, improving the detection accuracy, thereby realizing automatic visual inspection of the cross-flow fan blade 9, and the shooting effect is good.

[0046] Furthermore, the detection camera 61 and the coaxial light source 62 are positioned directly above the placement space, with the detection camera 61 positioned above the coaxial light source 62, and the back-side light source 63 positioned at the lower front or lower rear side of the placement space. When feeding material, the cross-flow fan 9 can feed material from the side opposite the back-side light source 63.

[0047] Furthermore, there is one detection camera 61, and a camera movement drive unit 64 is provided on the frame 5. The detection camera 61 is located on the moving end of the camera movement drive unit 64. The camera movement drive unit 64 can drive the detection camera 61 to move in the left and right directions to detect different axial positions of the cross-flow fan blade 9. The camera movement drive unit 64 can be a lead screw motion module, a gear and rack motion module, etc.

[0048] In some specific embodiments, reference is made to Figure 4 The frame 5 is also equipped with a clamping shaft moving drive unit 19, which is connected to the first base 11 in a transmission manner. The clamping shaft moving drive unit 19 can drive the clamping shaft assembly 1 to move closer to or away from the supporting assembly 2. The testing equipment also includes a receiving mechanism 7, which includes a receiving lifting drive unit 71 and a receiving component 72. The receiving component 72 is located on the lower side of the placement space. The receiving lifting drive unit 71 is connected to the receiving component 72 in a transmission manner. The receiving lifting drive unit 71 can drive the receiving component 72 to move in the up and down direction. When the receiving component 72 moves upward, it can receive the cross-flow fan blade 9 that has detached from the clamping shaft assembly 1 and the supporting assembly 2.

[0049] After the inspection is completed, the receiving lifting drive unit 71 of the receiving mechanism 7 drives the receiving component 72 to rise to the lower side near the cross-flow fan blade 9; the end shaft gripper 12 releases the end shaft 91 of the cross-flow fan blade 9, and after the end shaft 91 is pushed out of the end shaft gripper 12, the clamping shaft moving drive unit 19 drives the clamping shaft assembly 1 away from the supporting assembly 2, leaving space for the cross-flow fan blade 9 to move out of the supporting assembly 2; then, the pushing component 32 of the pushing mechanism 3 pushes the cross-flow fan blade 9 to the side near the clamping shaft assembly 1, and the second end of the cross-flow fan blade 9 leaves the supporting assembly 2, and the cross-flow fan blade 9 falls on the receiving component 72; then the receiving lifting drive unit 71 drives the receiving component 72 to move downward, removing the inspected cross-flow fan blade 9 and unloading it, so that a new cross-flow fan blade 9 to be inspected can be loaded and inspected. This unloading method is not blocked by the back light source 63, the back light source 63 does not need to move up and down, and the structure is more compact. The clamping shaft moving drive unit 19 and the receiving lifting drive unit 71 can be cylinders or lead screw motion modules, etc.

[0050] Furthermore, referring to Figure 3The testing equipment also includes a discharge plate 8, which is fixed on the frame 5 and located on the lower side of the placement space. The discharge plate 8 is located on the side of the receiving mechanism 7. The discharge plate 8 is inclined up and down in the front-back direction. When the receiving component 72 moves downward, it can be lower than the discharge plate 8 so that the cross-flow fan 9 falls on the discharge plate 8.

[0051] The receiving part 72 supports the cross-flow fan blade 9 to move downward. When the cross-flow fan blade 9 falls onto the dropping plate 8, it stays on the dropping plate 8 and then slides down the dropping plate 8 at an angle to other positions. The material unloading structure is relatively simple.

The first receiving mechanism 7 also includes a receiving base 73, and a receiving lifting drive unit 71 is disposed on the receiving base 73. The receiving base 73 and the first base 11 are slidably connected to the frame 5 in the left and right direction. A position adjustment mechanism 74 is provided between the receiving base 73 and the frame 5. The position adjustment mechanism 74 can adjust the left and right position of the receiving base 73 on the frame 5. The clamping shaft moving drive unit 19 is connected to the receiving base 73 and the first base 11.

[0054] The lifting and supporting drive unit 24 can adjust the height of the second base 21, which, in conjunction with the height of the end shaft clamp 12, can accommodate cross-flow fan blades 9 of different diameters for testing, improving versatility. The first receiving mechanism 7, the clamping shaft assembly 1, and the clamping shaft moving drive unit 19 can be adjusted left and right to adjust the distance between themselves and the supporting assembly 2, thus accommodating cross-flow fan blades 9 of different lengths for testing, improving versatility. The first receiving mechanism 7 moves with the clamping shaft assembly 1 to better receive the first end of the cross-flow fan blade 9. The lifting and supporting drive unit 24 can adopt a screw motion module or a rack and pinion motion module, etc. The receiving base 73 and the first base 11 can be slidably connected to the frame 5 via a slide rail slider. The position adjustment mechanism 74 can adopt a screw and nut adjustment mechanism or a rack and pinion adjustment mechanism. The clamping shaft moving drive unit 19 can adopt a cylinder, the cylinder body of which can be fixed on the first base 11, and the piston rod of which can be connected to the receiving base 73.
