Description

Technical Field

[0001] The utility model relates to the technical field of axial and end face runout detection of axial flow fans, and particularly relates to a structural improvement of a fan detection device. Background Art

[0002] When detecting the axial and radial runout of a fan, it is necessary to fix the fan first. To achieve the support and fixation of the fan, a rotating shaft structure is set up. The fan is installed on the rotating shaft, and the rotating shaft is connected to the motor. When the motor rotates, it drives the fan to rotate. When the fan rotates, the fan will pass by a detection component on one side of it. The detection component detects the contour of the fan, analyzes the obtained contour shape, and then obtains the axial and radial runout of the fan.

[0003] The existing detection component for detection is a 3D detection scanner, which can scan the contour shape of the fan during the rotation of the fan, transmit the fan contour image to the control unit of the industrial control computer, and the control unit automatically calculates data such as the end face and radial runout of the fan and the fan diameter.

[0004] For the existing fan detection equipment, the rotating shaft for fixing the fan is generally directly connected to the motor, and the rotating shaft model is single, and it can only detect one type of fan. When the fan model to be detected changes, it cannot be detected, and the versatility is poor. Summary of the Utility Model

[0005] In view of the above technical problems existing in the fan detection equipment pointed out in the background art, a fan detection equipment is proposed. The rotating shaft for assembling the fan is correspondingly provided with a connecting component, and the inner diameter of the insertion part of the connecting component for fixing the positioning component is adjustable so that it can match different types of fans, improving the versatility of the entire equipment.

[0006] To achieve the above utility model purpose, the present utility model adopts the following technical solutions to be realized:

[0007] In some embodiments of the present application, a fan detection equipment is provided, including:

[0008] A frame, in which a detection table is arranged;

[0009] A detection component, assembled on the detection table, capable of obtaining the contour of the fan for parameter detection of the fan;

[0010] A positioning component, used for assembling and positioning the fan;

[0011] A connecting component, rotatably connected to the detection table, used for driving the positioning component and the fan to rotate for detection. The connecting component includes:

[0012] The insertion part is used to assemble the positioning part, and the insertion part is configured such that: the inner diameter size is adjustable to fit positioning parts of different sizes.

[0013] In the fan detection device in the above solution, the connection part corresponding to the positioning part for assembling the fan is configured to assemble and fix the positioning part, and the inner diameter of the insertion part of the connection part is set to be adjustable, so that the insertion part can be used to match positioning parts of different sizes. When the type of the fan to be detected changes, the size of the positioning part for positioning it also changes accordingly. Different types of fans can be positioned and fixed by replacing different positioning parts, making this device capable of detecting multiple different types of fans and improving the versatility of the entire device.

[0014] In some embodiments of the present application, the connection part includes:

[0015] The first connection part passes through the detection table and is rotatably connected to the detection table;

[0016] The second connection part is assembled inside the first connection part, and the insertion part for inserting the fan shaft sleeve is formed inside the second connection part, and it includes:

[0017] The notch part has at least one, penetrates the side wall of the second connection part to the insertion part, and extends along the axial direction of the second connection part to one end of the second connection part;

[0018] The third connection part is movably connected to the first connection part and abuts against the second connection part, and is configured to: apply a force to the second connection part by moving relative to the first connection part so that the second connection part deforms radially through the notch part.

[0019] Through the first connection part, the second connection part and the third connection part that are connected and cooperated with each other, a force can be applied to the second connection part by moving the third connection part, so that the size of the internal insertion part is changed to fit positioning parts of different outer diameters.

[0020] By setting the notch part to penetrate to the insertion part and extend to the end position of the second connection part, the second connection part can deform along the radial direction of the insertion part when it receives a radial force.

[0021] In some embodiments of the present application, the second connection part includes a first end close to the fan; and

[0022] A second end, which is oppositely arranged to the first end;

[0023] A plurality of the notch parts are arranged along the circumferential direction of the second connection part;

[0024] At least part of the notch parts are opened from the first end and extend to a position close to the second end;

[0025] Alternatively, at least part of the notch is opened from the second end and extends to a position close to the first end;

[0026] Alternatively, the notch is opened from the first end and extends to a position close to the second end.

[0027] The partial notch portion is opened from the second end and extends to a position close to the first end.

[0028] By configuring the notch portion to include a structure extending to either end of the second connecting component as described above but not limited to the above-mentioned opening structure, it is ensured that the second connecting component deforms when subjected to force to match different positioning components.

[0029] In some embodiments of the present application, the second connecting member includes:

[0030] The first diameter-reducing portion has an outer diameter that gradually increases in a direction away from the fan;

[0031] A second diameter-reducing portion, the outer diameter of which gradually decreases in a direction away from the fan; and

[0032] The neck is connected between the first diameter reducing portion and the second diameter reducing portion.

[0033] By arranging the second connecting member into a first diameter-reducing portion and a second diameter-reducing portion structure, the second connecting member can be matched with the third connecting member and the first connecting member respectively and deformed when subjected to pressure.

[0034] In some embodiments of the present application, the third connecting member is sleeved on the second connecting member, and the third connecting member includes a first reducing fitting portion, and the first reducing fitting portion is configured to apply a force to the first reducing portion to change the inner diameter of the insertion portion when the third connecting member moves relative to the first connecting member.

[0035] The third connecting member is movably connected to the first connecting member so that it can move relative to the first connecting member to change its position. Since it abuts against the second connecting member, it applies a force to squeeze the second connecting member when it moves, causing it to deform radially through the notch and change its radial size.

[0036] When the distance the third connecting member moves relative to the first connecting member is different, the force it applies to the second connecting member is also different, so that the deformation of the second connecting member is also different. Therefore, the inner diameter of the insertion part of the second connecting member can be adjusted by adjusting the distance the third connecting member moves relative to the first connecting member, so that it can adapt to the installation of positioning components of different sizes.

[0037] In some embodiments of the present application, the third connecting member includes an internal thread portion, and an external thread portion is formed on the first connecting member. The third connecting member moves relative to the first connecting member through the cooperation of the internal thread portion and the external thread portion.

[0038] The third connecting member is screwed onto the first connecting member. By rotating the third connecting member, it can move relative to the first connecting member along the vertical direction, thereby changing the force applied to the second connecting member and facilitating the operation through the threaded connection method.

[0039] In some embodiments of the present application, a second reduced-diameter fitting portion for inserting the second reduced-diameter portion is formed inside the first connecting member, and the second reduced-diameter fitting portion is configured to: adapt to the outer contour of the second reduced-diameter portion.

[0040] Through the cooperation of the second reduced-diameter portion and the second reduced-diameter fitting portion, the guiding of the assembly of the second connecting member can be realized, so that the second connecting member can be quickly assembled in place.

[0041] Since the second reduced-diameter portion is reduced in diameter and the outer diameter gradually becomes smaller, and the second reduced-diameter fitting portion is also reduced in diameter, when the second connecting member moves downward under force, it can be clamped by the second reduced-diameter fitting portion in an adapted manner. Through the structures of the second reduced-diameter portion and the second reduced-diameter fitting portion, it is ensured that the second connecting member and the first connecting member are always tightly inserted, ensuring the fixing effect on the positioning component.

[0042] In some embodiments of the present application, the following are formed on the positioning component:

[0043] A positioning portion for inserting the fan bushing to limit the circumferential rotation of the fan bushing; and

[0044] A supporting portion formed at the circumferential position of the positioning portion and configured to: abut against the bottom position of the fan bushing to limit the position of the fan.

[0045] During assembly, the bushing of the fan can be inserted onto the positioning portion to realize the insertion and fixing of the fan, and the circumferential rotation of the fan is limited through the positioning portion.

[0046] The supporting portion can be used to support the fan bushing, thereby realizing the support of the fan and preventing the fan from sliding down.

[0047] Through the provided supporting portion, the fan bushing can also be limited, so that when the fan bushing is inserted onto the positioning portion, it can be quickly inserted in place through the limitation of the supporting portion.

[0048] In some embodiments of the present application, it includes:

[0049] A bidirectional moving mechanism assembled to the detection table, including:

[0050] The X-direction moving mechanism is slidably connected to the detection table and can move along the X direction of the detection table;

[0051] The Z-direction moving mechanism is connected to the X-direction moving mechanism and can move in the X direction driven by the X-direction moving mechanism. The Z-direction moving mechanism includes:

[0052] A Z-direction moving block that can move along the Z direction, and the detection component is connected to the Z-direction moving block.

[0053] The bidirectional moving mechanism is connected to the detection component and can drive the detection component to move in the X direction and the Z direction to adjust and change the position of the detection component.

[0054] When detecting different types of fans, the positions where the detection components need to be arranged, such as the height position, may be different. By controlling the operation of the bidirectional moving mechanism, the position of the detection component can be adjusted to adapt to the requirements of different fan detection positions, ensuring the detection accuracy of fan parameters.

[0055] In some embodiments of the present application, it includes:

[0056] A support table is fixed at one side position of the frame, and a weighing device is arranged on the support table. The weighing device is configured to: weigh and measure the fan to be detected.

[0057] The weighing device can weigh the fan used for detection to obtain the weight of the weighed fan, so as to achieve the effect of multi-parameter measurement of the fan.

[0079] In some embodiments of the present application, a fan detection device is provided. Referring to Figures 1 - 3 as shown, the detection device includes a frame 100, a detection table 200 assembled on the frame 100, a detection component 300, a connection component 500, and a positioning component 400 assembled on the detection table 200.

[0080] The detection table 200 is horizontally assembled on the frame 100, dividing the frame 100 into an upper space 110 and a lower space.

[0081] The detection table 200 is used to place the positioning component 400, the connection component 500 for fixing the fan, and the detection component 300 for detecting the fan. The above components are located in the upper space 110.

[0082] The mounting area of the surface of the detection table 200 is covered with a thick aluminum oxide plate. The thickness of the aluminum plate is greater than 15 mm, which is flat and has good rigidity. The height of the detection table 200 from the ground is about 800 mm.

[0083] During setting, the positioning component 400 and the detection component 300 are arranged side by side on the detection table 200 in sequence, which can ensure that when the fan rotates, the detection component 300 can detect the fan along one week, improving the detection accuracy.

[0084] A protective plate 120 is provided on the frame 100 above the detection table 200. Through the protective plate 120, the detection component 300 inside the detection table 200 can be protected, shielding the influence of the external environment on the detection.

[0085] The protective plate 120 is set as a transparent plate, which is convenient for users to directly observe the rotation state of the detected fan.

[0086] A surrounding plate 130 is provided around the lower space at the lower part of the frame 100. The surrounding plate 130 is fixed on the frame 100 to form a cabinet. A lower space is formed inside the cabinet, which can be used to accommodate electrical control devices or computer components, realizing the full utilization of the space.

[0087] For the convenience of repairing electrical components in the cabinet, an inspection door 140 is also provided on the cabinet. It can be opened and closed, facilitating users to perform repair operations.

[0088] In some embodiments, the panel material used around the frame 100 is galvanized steel sheet with spraying. The thickness of the steel sheet is greater than 1.2 mm, the color is microcomputer gray, the surface is smooth, and the frame 100 is made of steel profiles with sufficient strength.

[0089] In some embodiments, casters 150 and supporting feet are provided at the bottom of the frame 100. By rolling the casters 150, the entire device can be conveniently moved to change its position. Through the setting of the supporting feet, the supporting effect of the device can be ensured after the entire device is moved in place.

[0090] The detection component 300 is assembled on the detection table 200 and can at least obtain the contour dimensions of the fan, providing a basis for the radial and end face runout of the fan.

[0091] The detection component 300 is a 3D scanner. During the process of the fan being driven to rotate, the 3D scanner can scan the contour of the fan to obtain the entire contour shape of the fan.

[0092] The fan detection device includes a control unit. The detection component 300 is mainly used to cooperate with the control unit to obtain parameter values such as the radial and end face runout of the detected fan.

[0093] The detection component 300 transmits the fan contour to the control unit. The control unit analyzes the size of the fan based on the received fan contour information, and then obtains the corresponding radial or end face runout value.

[0094] In some embodiments of the present application, the fan detection device includes a display screen 160. The display screen 160 is installed on one side of the frame 100 through a column and a curved arm bracket, and is used to display the fan contour processed by the control unit and the relevant dimensions of the fan.

[0095] Through the setting of the display screen 160, users can more intuitively view the relevant detection parameter values of the detected fan.

[0096] In some embodiments of the present application, the fan detection device further includes a weighing device 180. Through the weighing device 180, the fan used for detection can be weighed to obtain the weight of the weighed fan.

[0097] A support table 170 is provided on one side of the frame 100. The support table 170 is arranged horizontally and is fixedly connected to the frame 100 through a reinforcing rib.

[0098] The weighing device 180 is placed on the support table 170, and the support table 170 is used to carry and place the weighing device 180.

[0099] The weighing device 180 communicates with the control unit and can be used to transmit the weight data obtained by weighing to the control unit and display it on the display screen 160 electrically connected to the control unit.

[0100] Each of the fans to be measured is correspondingly provided with a two-dimensional code, and the fan detection device is also correspondingly provided with a two-dimensional code scanner. The two-dimensional code scanner communicates with the control unit. Before measuring the fan, the two-dimensional code of the fan to be detected is obtained by scanning with the two-dimensional code scanner.

[0101] When the control unit receives the two-dimensional code scanned by the two-dimensional code scanner, it can automatically obtain the detection reference parameters corresponding to the fan of this two-dimensional code for later detection use.

[0102] With the structural method in which multiple fans are each configured with a corresponding two-dimensional code, the relevant parameters of each fan detection can be correspondingly recorded under the corresponding fan two-dimensional code, realizing the classified recording and storage of the parameters of each detected fan, and ensuring the correspondence and accuracy of the detection parameters of each fan.

[0103] In some embodiments of the present application, the device for detecting the fan is further provided with an alarm component. When it is detected that the parameters of the fan do not correspond to the detection reference parameters pre-stored in the control unit, the control unit controls the alarm component to act and issue an alarm, so as to stop operations such as testing.

[0104] In some embodiments of the present application, as shown in Figures 4 - 7 the fan detection device includes:

[0105] A positioning component 400, which is used to insert and position the fan. By positioning the fan through the positioning component 400, it is ensured that the fan will not rotate or shake during the rotation process, avoiding the influence of the fan position movement on the detection accuracy of the fan.

[0106] In some embodiments of the present application, the axial flow fan includes a shaft sleeve and a plurality of spiral fan blades arranged circumferentially along the shaft sleeve of the axial flow air duct.

[0107] The positioning component 400 is formed with:

[0108] A positioning portion 410, which is used to insert the fan shaft sleeve and limit the circumferential rotation of the fan shaft sleeve;

[0109] During assembly, the shaft sleeve of the fan can be inserted onto the positioning portion 410 to achieve the insertion and fixation of the fan, and the circumferential rotation of the fan is limited through the positioning portion 410.

[0110] In some embodiments of the present application, the cross-sectional shape of the positioning portion 410 is adapted to the cross-sectional shape of the fan shaft sleeve, and the cross-sectional shape of the positioning portion 410 is non-circular.

[0111] By the non-circular positioning portion 410 and the non-circular fan shaft sleeve being inserted and fitted together, the limit of the rotation of the fan shaft sleeve can be achieved.

[0112] In some embodiments of the present application, the cross-section of the fan shaft sleeve is semi-circular, and the positioning portion 410 is a positioning protrusion with a semi-circular cross-section. When the fan shaft sleeve is inserted inside the positioning portion 410, the circumferential limit of the fan shaft sleeve can be achieved through the semi-circular positioning protrusion.

[0113] In some embodiments of the present application, the cross-sectional shape of the fan shaft sleeve is rectangular or polygonal, and the positioning portion 410 is adapted to its shape, and the circumferential rotation limit effect of the fan can also be achieved.

[0114] In some embodiments of the present application, the positioning member 400 includes a supporting portion 420 formed at the circumferential position of the positioning portion 410 and configured to support and limit the fan at the bottom position of the fan shaft sleeve.

[0115] The supporting portion 420 can be used to support the fan shaft sleeve, and thus the support of the fan is realized, avoiding the fan from slipping downwards.

[0116] By providing the supporting portion 420, the fan shaft sleeve can also be limited, so that when the fan shaft sleeve is inserted on the positioning portion 410, it can be quickly inserted in place through the limit of the supporting portion 420.

[0117] In some embodiments of the present application, the positioning member 400 includes a positioning body portion 430, and the positioning portion 410 is formed by extending on the top of the positioning body portion 430.

[0118] The outer diameter of the positioning body portion 430 is larger than the outer diameter of the positioning portion 410. A limiting platform is formed at the docking position of the positioning portion 410 and the positioning body portion 430, and the limiting platform forms the supporting portion 420.

[0119] When the fan is inserted on the positioning portion 410 through the shaft sleeve above it, the bottom of the fan shaft sleeve abuts against the limiting platform at the lower position, and the bottom of the fan shaft sleeve is supported and positioned by the limiting platform.

[0120] When the positioning member 400 is provided, multiple positioning members 400 can be provided. The outer diameter dimensions of the multiple positioning members 400 are different and are actually made according to the sizes of the fan and the shaft hole. The surface is smooth, the coaxiality is good, and heat treatment is carried out to have a high hardness so that it can be adapted to different types of fans and support and position different types of fans.

[0121] In some embodiments of the present application, the positioning member 400 includes a connecting portion 440, and the connecting portion 440 is used to be inserted into the insertion portion 525 of the connecting member 500.

[0122] The connecting portion 440 is a connecting section, and its outer diameter is smaller than the outer diameter of the positioning body portion 430.

[0123] When the connecting portion 440 is inserted into the connecting component 500, the positioning body portion 430 above it cannot be inserted into the connecting component 500 due to its large outer diameter, and can only abut against the top of the connecting component 500.

[0124] By setting the connecting portion 440 to have a structure with an outer diameter smaller than that of the positioning body portion 430, when the connecting portion 440 cooperates with the connecting component 500, the connecting portion 440 can be quickly and accurately inserted in place through the limiting effect of the positioning body portion 430.

[0125] In some embodiments of the present application, referring to Figures 4 - 7 As shown, the device for detecting a fan includes a connecting component 500, which is rotatably connected to the detection table 200 and is used to drive the positioning component 400 and the fan to rotate for detection.

[0126] The connecting component 500 and the positioning component 400 are assembled and connected, and a fan is assembled on the positioning component 400. When the connecting component 500 rotates, it can drive the positioning component 400 and the fan connected to the positioning component 400 to rotate.

[0127] In some embodiments of the present application, the connecting component 500 includes:

[0128] An insertion portion 525 for assembling the positioning component 400. The positioning component 400 for fixing the fan is assembled in the insertion portion 525 of the connecting component 500, and the support and fixation of the positioning component 400 are realized through the connecting component 500.

[0129] The connecting component 500 is rotatably connected to the detection table 200. When the connecting component 500 rotates, it can correspondingly drive the positioning component 400 and the fan assembled above it to rotate synchronously, so as to detect the peripheral contour of the fan through the detection component 300.

[0130] The insertion portion 525 is configured such that the inner diameter can be adjusted to adapt to positioning components 400 of different sizes.

[0131] When the connecting component 500 fixes the positioning component 400, the inner diameter of the insertion portion 525 can be adjusted according to the actual size of the positioning component 400, so that it can lock and fix positioning components 400 of different sizes.

[0132] In the fan detection device in the above solution, a connection component 500 for assembling and fixing the positioning component 400 is correspondingly configured for the positioning component 400 for assembling the fan, and the inner diameter of the insertion part 525 of the connection component 500 is set to be adjustable, so that the insertion part 525 can be used to match positioning components 400 of different sizes. When the type of fan to be detected changes, the size of the positioning component for positioning it also changes accordingly. Different types of fans can be positioned and fixed by replacing different positioning components 400, enabling this device to detect multiple different types of fans and improving the versatility of the entire device.

[0133] In some embodiments of the present application, referring to Figures 4 - 7 as shown, the connection component 500 is composed of a first connection member 510, a second connection member 520, and a third connection member 530 that are connected and cooperated with each other.

[0134] In some embodiments of the present application, referring to Figure 7 as shown, the first connection member 510 passes through the detection table 200 and is rotatably connected to the detection table 200.

[0135] The first connection member 510 is a first connecting shaft body with a variable diameter, which extends downward from above the detection table 200 and penetrates the detection table 200 to extend to a position below the detection table 200.

[0136] The detection table 200 includes a table body 220 and an assembly bushing 210. The assembly bushing 210 is used to install the first connection member 510, and the first connection member 510 is rotatably connected within the assembly bushing 210 through a bearing to achieve the rotational connection between the connection component 500 and the table body 220.

[0137] During assembly, the assembly bushing 210 is fixedly locked to the table body 220 by bolts, and the rotational first connection member 510 can be supported through the assembly bushing 210.

[0138] A driving device 600 and a transmission device are provided at the bottom of the detection table 200. The transmission device and the first connection member 510 are used to transmit the power of the driving device 600 to the first connection member 510 to drive the first connection member 510 to rotate.

[0139] In some embodiments of the present application, a first protrusion 512 is formed at the bottom of the first connection member 510. The driving device 600 is a driving motor, and the transmission device is a belt pulley transmission device, including a main belt pulley 610, a driven belt pulley 620, and a transmission belt 630 wound between the main belt pulley 610 and the driven belt pulley 620. The driven belt pulley 620 is assembled on the first protrusion 512.

[0140] When the fan needs to be detected, the drive motor starts to drive the driving pulley to rotate, and then drives the driven pulley 620 connected to it in transmission to drive the first connecting member 510 to rotate, so as to realize the rotation of the first connecting member 510 driving the entire connecting component 500.

[0141] In some embodiments of the present application, referring to Figure 7 , Figure 10 as shown, the connecting component 500 includes a second connecting member 520, which is assembled inside the first connecting member 510. The second connecting member 520 is assembled inside the first connecting member 510 to realize the connection with the first connecting member 510, and the second connecting member 520 is supported by the first connecting member 510.

[0142] An insertion part 525 for inserting the positioning component 400 is formed inside the second connecting member 520.

[0143] The insertion part 525 is an insertion cavity formed inside the second connecting member 520 and penetrating through both ends of the second connecting member 520, and the insertion cavity is used for inserting the positioning component 400.

[0144] The second connecting member 520 includes a notch part 524, at least one is provided, which penetrates the side wall of the second connecting member 520 to the insertion part 525, and is arranged along the axial direction of the second connecting member 520 and extends to one end of the second connecting member 520.

[0145] The notch part 524 is a long notch formed on the second connecting member 520, and the long notch is arranged along the axis direction and penetrates the side wall of the second connecting member 520.

[0146] When the long notch is arranged, one or more can be opened. The opening end of the long notch can be at any position on the side wall of the second connecting member 520, and the other end extends to any one end position of the second connecting member 520.

[0147] By setting the notch part 524 to penetrate to the insertion part 525 and extend to the end position of the second connecting member 520, it can be ensured that when the second connecting member 520 is subjected to a radial force, it can deform along the radial direction of the insertion part 525.

[0148] In some embodiments of the present application, the second connecting member 520 includes a first end 526 close to the fan and a second end 527 opposite to the first end 526.

[0149] A plurality of the notch parts 524 are arranged along the circumferential direction of the second connecting member 520;

[0150] Some of the notch parts 524 are opened from the first end 526 and extend to a position close to the second end 527;

[0151] The remaining notch portion 524 is opened from the second end 527 and extends to a position close to the first end 526 .

[0152] Part of the notch 524 is opened from the first end 526, and part of the notch 524 is opened from the second end 527, so that both ends of the second connecting member 520 can be deformed when subjected to force, thereby ensuring the deformation effect.

[0153] When the notch portions 524 are arranged, the notch portions 524 opened from the first end 526 and the notch portions 524 opened from the second end 527 are arranged alternately, so as to ensure that the second connecting member 520 is uniformly deformed when subjected to an external force.

[0154] Alternatively, a plurality of notches 524 opened from the first end 526 are arranged between two adjacent notches 524 opened from the second end 527;

[0155] Alternatively, a plurality of notches 524 opened from the second end 527 are arranged between two adjacent notches 524 opened from the first end 526 .

[0156] In some embodiments of the present application, the second connecting member 520 includes a first end 526 close to the fan; and a second end 527 arranged opposite to the first end 526, and the second end 527 is farther away from the fan than the first end 526.

[0157] The notch portions 524 are provided in plurality and are arranged along the circumference of the second connecting member 520;

[0158] A plurality of notches 524 are formed from the first end 526 and extend to a position close to the second end 527 .

[0159] The notch 524 is arranged to extend from the first end 526 to near the second end 527 , so that the second connecting member 520 can be radially deformed when the second connecting member 520 is subjected to force, so that the second connecting member 520 can adapt to positioning components 400 of different sizes.

[0160] In some embodiments of the present application, the second connecting member 520 includes a first end 526 close to the fan and a second end 527 disposed opposite to the first end 526 .

[0161] The notch portions 524 are provided in plurality and are arranged along the circumference of the second connecting member 520;

[0162] A plurality of notches 524 are formed from the second end 527 and extend to a position close to the first end 526 .

[0163] The notch portion 524 is arranged to extend from the second end 527 to near the first end 526, which can also cause the second connecting member 520 to deform radially when the second connecting member 520 is stressed, so that the second connecting member 520 can adapt to positioning members 400 of different sizes.

[0164] In some embodiments of the present application, referring to Figure 7 , Figure 11 As shown, the connecting member 500 includes a third connecting member 530, which is movably connected to the first connecting member 510 and abuts against the second connecting member 520, and is configured to: when moving relative to the first connecting member 510, apply a force to the second connecting member 520 to cause it to deform radially through the notch portion 524.

[0165] The third connecting member 530 is movably connected to the first connecting member 510 so that it can move relative to the first connecting member 510 to change its position. Since it abuts against the second connecting member 520, when it moves, it will apply a force to squeeze the second connecting member 520 to cause it to deform radially through the notch portion 524 and change the radial dimension.

[0166] When the distance that the third connecting member 530 moves relative to the first connecting member 510 is different, the magnitude of the force applied to the second connecting member 520 is also different, so that the magnitude of the deformation of the second connecting member 520 is also different. Therefore, the inner diameter size of the insertion portion 525 of the second connecting member 520 can be adjusted by adjusting the distance that the third connecting member 530 moves relative to the first connecting member 510, so that it can adapt to the installation of positioning members 400 of different sizes.

[0167] In some embodiments of the present application, the third connecting member 530 includes an internal thread portion, and an external thread portion is formed on the first connecting member 510. The third connecting member 530 moves relative to the first connecting member 510 through the cooperation of the internal thread portion and the external thread portion.

[0168] The internal thread portion is the internal thread formed on the third connecting member 530, and the external thread portion is the external thread formed on the first connecting member 510. The third connecting member 530 and the first connecting member 510 are threadedly connected through the cooperation of the internal thread and the external thread.

[0169] The third connecting member 530 is screwed onto the first connecting member 510. By rotating the third connecting member 530, it can move relative to the first connecting member 510 in the vertical direction, thereby changing the force applied to the second connecting member 520, and the connection method of screwing is convenient for operation.

[0170] In some embodiments of the present application, referring to Figure 7As shown, the second connecting member 520 includes a first diameter-changing portion 521, whose outer diameter gradually increases in the direction away from the first end 526.

[0171] The first diameter-changing portion 521 forms the first diameter-changing section of the second connecting member 520. The first end 526 is formed at one end of the first diameter-changing portion 521 close to the fan, and a first diameter-changing surface is formed on the first diameter-changing portion 521.

[0172] In some embodiments of the present application, the third connecting member 530 is sleeved on the second connecting member 520. The third connecting member 530 includes a first diameter-changing mating portion 531, which is configured to: when the third connecting member 530 moves relative to the first connecting member 510, apply a force to the first diameter-changing portion 521 to change the inner diameter of the insertion portion 525.

[0173] The first diameter-changing mating portion 531 is a first diameter-changing mating section, and a first diameter-changing mating surface adapted to the first diameter-changing surface is formed on the first diameter-changing mating portion 531.

[0174] When the third connecting member 530 moves along the first connecting member 510, the first diameter-changing surface that fits and mates with it will be pressed by the first diameter-changing mating surface, and the force acts on the second connecting member 520 to cause its radial deformation.

[0175] In some embodiments of the present application, the first diameter-changing surface is a conical surface or an inclined surface, and the first diameter-changing mating surface is adapted to the shape of the first diameter-changing surface.

[0176] When the third connecting member 530 moves downward, a force perpendicular to the first diameter-changing surface will be applied to the first diameter-changing surface through the first diameter-changing mating surface. This force can be decomposed into two component forces, a horizontal force and a vertical force along the radial direction. The force along the radial direction can radially squeeze the second connecting member 520 to cause its radial deformation.

[0177] In some embodiments of the present application, the second connecting member 520 includes a second diameter-changing portion 522 and a neck portion 523. The outer diameter of the second diameter-changing portion 522 gradually decreases in the direction away from the first end 526.

[0178] The second diameter-changing portion 522 is a second diameter-changing section, which is farther from the first end 526 than the first diameter-changing portion 521. The neck portion 523 is a neck section for connecting the first diameter-changing portion 521 and the second diameter-changing portion 522.

[0179] A second diameter-changing mating portion 511 for inserting the second diameter-changing portion 522 is formed inside the first connecting member 510. The second diameter-changing mating portion 511 is configured to: be adapted to the outer contour of the second diameter-changing portion 522.

[0180] The second diameter-changing mating portion 511 is a second diameter-changing cavity formed within the first connecting member 510 for inserting the second diameter-changing section.

[0181] Through the cooperation of the second diameter-changing portion 522 and the second diameter-changing mating portion 511, the guiding of the assembly of the second connecting member 520 can be achieved, enabling the second connecting member 520 to be quickly assembled in place.

[0182] After the radial contraction deformation of the second connecting member 520, its inner diameter will become smaller, and there may be a gap in the cooperation between the second diameter-changing portion 522 and the second diameter-changing cavity, resulting in loose connection and shaking between the second connecting member 500 and the first connecting member 500.

[0183] However, the force exerted by the above-mentioned first diameter-changing mating surface on the first diameter-changing surface not only provides a horizontal radial force to the second connecting member 520 but also has a vertical force. The vertical force will cause the second connecting member 520 to move downward relative to the first connecting member 510.

[0184] Since the second diameter-changing portion 522 is diameter-changing and its outer diameter gradually becomes smaller, and the second diameter-changing mating portion 511 is also diameter-changing, when the second connecting member 520 moves downward, it can be adaptively clamped by the second diameter-changing mating portion 511. By the downward-moving second connecting member 520, it is ensured that the second connecting member 520 and the first connecting member 510 always maintain a tight insertion, ensuring the fixing effect on the positioning member 400.

[0185] Meanwhile, at least a part of the notch portion 524 formed on the second connecting member 500 is also located on the second diameter-changing portion 522. When the second connecting member 520 moves downward, the notch portion 524 also deforms accordingly to ensure the tight insertion between the second connecting member 520 and the first connecting member 510.

[0187] A bidirectional moving mechanism, assembled to the detection table 200. The bidirectional moving mechanism is connected to the detection component 300 and can drive the detection component 300 to move in the X direction and the Z direction to adjust and change the position of the detection component 300.

[0188] When detecting different types of fans, the positions where the detection component 300 needs to be arranged, such as the height position, etc., may be different. By controlling the operation of the bidirectional moving mechanism, the position of the detection component 300 can be adjusted to adapt to the requirements of different fan detection positions, ensuring the detection accuracy of fan parameters.

[0191] The Z-direction moving mechanism 820 is connected to the X-direction moving mechanism 810 and can move in the X direction driven by the X-direction moving mechanism 810. The Z-direction moving mechanism 820 includes a Z-direction moving block 830 that can move along the Z direction, and the detection component 300 is connected to the Z-direction moving block 830.

[0192] The Z-direction moving mechanism 820 can be a Z-direction linear module driven by a motor, which is connected to the X-direction linear module. When the X-direction linear module moves in the X direction, it can drive the detection component 300 located on the Z-direction moving block 830 to move in the X direction for X-direction position adjustment.

[0193] When the Z-direction moving block 830 moves up and down, it can drive the detection component 300 to move up and down to change the adjusted height position.

[0194] In some embodiments of the present application, the bidirectional moving mechanism includes a fixed seat 840, which is connected to the Z-direction moving block 830. A limiting rod 850 is provided on the fixed seat 840 to limit the detection component 300 and prevent it from falling off the fixed seat 840.
