DETAILED DESCRIPTION

[0027] 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.

[0028] Embodiment 1: Please refer to the diagrams of a fan blade processing detection device in Figures 1 to 9, which includes a body 1, a driving mechanism 4, a measuring mechanism 5, an extrusion mechanism 8 and a detection mechanism 9. The body 1 is provided with a detection cavity 2, and a box door 3 is hinged on the body 1. The measuring mechanism 5 includes two groups of clamping plates 6 installed in the detection cavity 2. A laser rangefinder 7 is provided in the body 1. The measuring mechanism 5 is used to link the clamping plates 6 on both sides to gradually approach the fan blade 39 when the driving mechanism 4 is running, and record the moving distance of the clamping plate 6 when the clamping plate 6 and the fan blade 39 are just in contact with each other through the laser rangefinder 7, so as to obtain the size of the fan blade 39. The extrusion mechanism 8 is installed in the body 1 and is used to continuously The clamping plate 6 is controlled to move and squeeze the fan blade 39, and after squeezing to a set distance, the clamping plate 6 is driven to reset in the opposite direction, and the measuring mechanism 5 is driven again to move and measure, and the deformation and reset status of the fan blade 39 is judged by the size change value of the fan blade 39. The detection mechanism 9 includes a push plate 10 installed on the box door 3, and a sliding cavity 11 that can be connected to the detection cavity 2 is provided on the box door 3. The push plate 10 is connected to the inner wall of the sliding cavity 11 in a horizontal sliding direction. A plurality of groups of air outlets 12 that are connected to the sliding cavity 11 on all sides are evenly provided on the box door 3. The detection mechanism 9 is used to obtain the wind force value during the rotation of the fan blade 39 according to the moving distance of the push plate 10 to complete the wind force detection.

[0029] Please refer to Figures 5 to 9. The driving mechanism 4 in the figure is installed on the body 1, and is used to fix the fan blades 39 and drive the fan blades 39 for rotation detection. The driving mechanism 4 includes a mounting frame 22 fixedly installed in the detection chamber 2, and a driving motor 23 is fixedly connected to the mounting frame 22. The model of the driving motor 23 is preferably YYHS-40. The output end of the driving motor 23 is fixedly connected to the driving shaft 24, and one end of the driving shaft 24 is used to install the fan blades 39.

[0030] In this embodiment, the box door 3 is opened, and the fan blades 39, i.e., the fan blades, are installed on the driving shaft 24 in the detection chamber 2. The box door 3 is closed, and the driving motor 23 is started to drive the driving shaft 24 to rotate, so that the fan blades 39 blow the airflow from the rear of the body 1 to the push plate 10. At this time, since the air outlet 12 is blocked by a large part of the push plate 10, the airflow needs to continuously push the push plate 10 to be fully discharged through the air outlet 12. The greater the sliding distance of the push plate 10, the larger the through hole connecting the air outlet 12 and the sliding chamber 11, and the greater the air output. Therefore, the greater the wind force, the greater the sliding distance of the push plate 10. By obtaining the wind force value during the rotation of the fan blades 39 according to the moving distance of the push plate 10, the wind force detection is completed.

[0031] When the drive shaft 24 rotates, the clamping plates 6 on both sides will be driven to approach the fan blades 39 synchronously. When the side of the clamping plate 6 collides with the edge of the fan blades 39, the position of the clamping plate 6 at this time is recorded. The distance between the arc-shaped depressions of the two groups of clamping plates 6 is the diameter of the fan blades 39. Since the shape of the fan blades 39 is relatively irregular, it is difficult to align the two ends of the fan blades 39 and measure the precise value if measured directly by a handheld ruler. However, the device can effectively improve the efficiency and accuracy of the measurement. At the same time, it can observe whether the clamping plate 6 is pushed to slide back and forth during the rotation of the fan blades 39, and judge whether the size of the fan blades 39 is evenly distributed. If some blades are long and some are short, the clamping plate 6 will move back and forth.

[0032] The clamping plate 6 is continuously controlled to move and squeeze the fan blade 39, and after squeezing to a set distance, the clamping plate 6 is driven to reset in the reverse direction, and the measuring mechanism 5 is driven again to move and measure, and the deformation and reset status of the fan blade 39 is judged by the size change value of the fan blade 39. The measurement can be repeated many times. If the diameter of the fan blade 39 measured each time is the same or the difference is within the set range, it means that the fan blade 39 has a good ability to restore deformation after being squeezed by force. If the fan blade 39 is broken or deformed, the measured value will have a large difference, which is convenient for people to judge and the detection is more accurate and efficient.

[0033] Embodiment 2: Please refer to Figures 1 to 10 for the description of Embodiment 2. This embodiment further describes Embodiment 1. The measuring mechanism 5 shown in the figure also includes a fixed tube 13 fixedly mounted on both sides of the body 1. A sliding rod 14 is slidably connected in the fixed tube 13 along the horizontal direction. A sliding frame 15 is fixedly connected to one end of the sliding rod 14. A guide groove 16 is provided in the sliding frame 15. The clamping plate 6 is slidably connected to the inner wall of the guide groove 16 along the horizontal direction. The laser rangefinder 7 is fixedly mounted on one end of the fixed tube 13. The clamping plate 6 is arc-shaped, and the arc surface is a smooth metal surface. A control member 17 for sensing the fitting state and controlling the reset is provided on the clamping plate 6.

[0034] Please refer to Figures 1 to 10. The control member 17 in the figure includes a first spring 18 fixedly mounted on the clamping plate 6, one end of the first spring 18 is fixedly connected to a pressure sensor 19 fixedly connected to the sliding rod 14, the side of the sliding frame 15 is fixedly connected to a tension spring 20 fixedly connected to the body 1, and an inflatable member 21 is provided in the body 1 for inflating one end of the fixed tube 13 when the driving mechanism 4 is running.

[0035] Please refer to Figures 1 to 9. The inflatable member 21 shown in the figure includes an inflatable box 25 fixedly mounted on the body 1, the inflatable box 25 is connected to an output pipe 26, the side of the output pipe 26 is connected to a connecting pipe 27, one end of the connecting pipe 27 is connected to the fixed pipe 13, the inflatable box 25 is provided with a one-way valve 28 for controlling the one-way input of gas into the inflatable box 25, the extrusion mechanism 8 includes a control valve 38 fixedly mounted on the output pipe 26, and the drive shaft 24 is provided with a driving member 29 for driving the inflatable box 25 to be inflated.

[0036] Please refer to Figures 6 to 9. The driving member 29 in the figures includes a first pulley 30 coaxially fixedly mounted on the driving shaft 24, a second pulley 31 is rotatably connected in the body 1, a transmission belt 32 that is transmission-connected to the second pulley 31 is transmission-connected to the outer wall of the first pulley 30, a driving rod 33 is rotationally connected to the side non-center position of the second pulley 31, an inflation plate 34 is slidably connected in the vertical direction in the inflation box 25, and one end of the driving rod 33 is rotationally connected to the inflation plate 34.

[0037] In this embodiment, the driving shaft 24 drives the first pulley 30 to rotate, so that the transmission belt 32 drives the second pulley 31 to rotate, and the second pulley 31 drives the driving rod 33 to make the inflatable plate 34 reciprocate and rise and fall in the inflatable box 25, and the external gas is sucked into the inflatable box 25 through the one-way valve 28, and then discharged into the connecting pipe 27 through the output pipe 26. The gas enters the fixed pipe 13, so that the air pressure in the fixed pipe 13 increases, and the sliding rod 14 and the sliding frame 15 are pushed to drive the clamping plate 6 to move. When the surface fits with the edge of the fan blade 39, the fan blade 39 hits the clamping plate 6, so that the first spring 18 is compressed, and the pressure sensor 19 records the value. At the same time, the laser rangefinder 7 measures the moving distance of the sliding rod 14 at this time and transmits it to the body 1. The distance from the laser rangefinder 7 to the axis of the drive shaft 24 minus the distance measured at this time minus the distance from one end of the sliding rod 14 to the center of the arc surface of the clamping plate 6 is the distance from the arc surface of the clamping plate 6 to the axis of the drive shaft 24 at this time. Twice this length is the diameter value of the fan blade 39.

[0038] After that, the drive shaft 24 continues to rotate, and the inflation box 25 continues to fill gas into the output pipe 26, so that the clamping plate 6 continuously fits and squeezes the outer wall of the fan blade 39, and the first spring 18 is continuously compressed. When the value of the pressure sensor 19 reaches the set value, the extrusion of the fan blade 39 is completed, the drive motor 23 is stopped and the control valve 38 is opened to discharge the gas in the output pipe 26 and the fixed pipe 13, and the tension spring 20 pulls the sliding frame 15 to slide in the opposite direction and reset. After closing the control valve 38, the drive motor 23 is started again, so that the air pressure in the fixed pipe 13 rises again, and the diameter value of the fan blade 39 is measured again. By comparing the change in the diameter value, it is determined whether the fan blade 39 is broken or deformed and cannot be reset. Repeated measurements are made multiple times. If the diameters of the fan blades 39 measured each time are the same or the difference is within the set range, it means that the fan blades 39 have a good ability to recover deformation after being squeezed. If the fan blades 39 are broken or deformed, the measured values ​​will have a large difference, which is convenient for people to judge and the detection is more accurate and efficient.

[0039] Embodiment 3: Please refer to Figures 1 to 9 for an explanation of Embodiment 3. This embodiment further explains Embodiment 1. The detection mechanism 9 shown in the figure also includes a second spring 35 fixedly mounted on one side of the push plate 10. One end of the second spring 35 is fixedly connected to the box door 3. A measuring rod 36 is fixedly connected to the push plate 10. The measuring rod 36 passes through the box door 3, and scale grooves 37 are evenly opened on the measuring rod 36.

[0040] In this embodiment, when the fan blades 39 rotate, the push plate 10 is pushed to slide, compressing the second spring 35 to increase the air output of the air outlet 12. The sliding of the push plate 10 drives the measuring rod 36 to slide. When the position of the push plate 10 is relatively stable, by observing the value of the scale groove 37, it can be determined whether the wind force value of the fan blade 39 when it rotates to the set speed meets the standard. Since the fan blade 39 will quickly reach the maximum speed in a short time, the detection result will be completed when the clamping plate 6 does not collide with the edge of the fan blade 39 to avoid the influence of the clamping plate 6. At the same time, after the clamping plate 6 conflicts with the fan blade 39, the change in the wind force of the fan blade 39 when it is deformed can be measured by observing the change in the scale groove 37, and the numerical change can be uploaded to the control system inside the body 1 to complete accurate analysis and obtain more comprehensive and accurate detection results.
