Description

Technical Field

[0001] This invention relates to the technical field of hydraulic fan assembly, and more particularly to a hydraulic fan assembly machine. Background Technology

[0002] As is well known, a hydraulic fan is a device that uses hydraulic energy to drive the fan to rotate. It is mainly used in the heat dissipation system of engineering machinery, coal mines, oil equipment and other fields. It has the characteristics of stable speed, low noise and good heat dissipation effect.

[0003] The assembly of hydraulic fans involves steps such as pressing the stator, first oiling, installing gaskets, installing retaining rings, installing bearings, pressing the bearings, second oiling, installing fan blades, and pressing the fan blades. However, these steps are currently mainly completed manually by operators, resulting in low assembly efficiency for existing hydraulic fans.

[0004] Therefore, there is an urgent need for a hydraulic fan assembly machine to overcome one or more of the aforementioned defects. Summary of the Invention

A fan blade feeding conveyor for conveying fan blades to the fan blade mounting mechanism is provided next to the fan blade mounting mechanism.

[0007] Compared with existing technologies, this invention utilizes a design comprising a rotary ring rail, multiple tooling seats on the rotary ring rail, a bottom shell feeding conveyor line for conveying pre-assembled stator bottom shells to the tooling seats, a bottom shell loading robot for transferring the bottom shells conveyed by the bottom shell feeding conveyor line to the tooling seats, and a stator pressing mechanism, a first oiling mechanism, a gasket mounting mechanism, a buckle mounting mechanism, a bearing mounting mechanism, a bearing pressing mechanism, a second oiling mechanism, a fan blade mounting mechanism, and a finished product unloading robot, arranged sequentially along the length of the frame above the rotary ring rail and mounted on the frame, and further complemented by a fan blade feeding conveyor line next to the fan blade mounting mechanism for conveying fan blades to the fan blade mounting mechanism, thus achieving automatic assembly and automatic unloading of hydraulic fans.

[0034] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0035] Please see Figure 1 and Figure 2 The hydraulic fan assembly machine 100 of the present invention includes a frame 10a, a rotary ring rail 10b mounted on the frame 10a and capable of rotating in a circular motion in the length and height directions of the frame 10a, and a plurality of tooling seats 11 disposed on the rotary ring rail 10b and spaced apart along the rotation direction of the rotary ring rail 10b (see Figure 3 ), for pre-installed stator 220 (see Figure 17 The bottom shell 210 (see) Figure 17The system includes a bottom shell feeding conveyor 10c that transports the bottom shells 210 from the bottom shell feeding conveyor 10c to the tooling base 11, a bottom shell loading robot 10d that transfers the bottom shells 210 from the bottom shell feeding conveyor 10c to the tooling base 11, and a pressing stator mechanism 20a, a first oiling mechanism 20b, a gasket mounting mechanism 30, a buckle mounting mechanism 40, a bearing mounting mechanism 50a, a bearing pressing mechanism 50b, a second oiling mechanism 50c, a fan blade mounting mechanism 60, and a finished product unloading robot 70a. Next to the fan blade mounting mechanism 60 is a fan blade supply 230 (see...). Figure 17 The fan blade feeding conveyor line 70b conveys the fan blades to the pressing fan blade mechanism 60. Specifically, in Figure 1 and Figure 2 As an example, the hydraulic fan assembly machine 100 of the present invention also includes a method for adjusting the gasket 240 (see...). Figure 17 The gasket testing mechanism 70c is used for testing the retaining ring 250 (see...). Figure 17 The system includes a buckle detection mechanism 70d and a blade detection mechanism 80 for applying a preset upward pulling force to the fan blades 230 installed in the bottom housing 210 to detect whether the fan blades 230 are properly installed. The blade detection mechanism 80 is mounted on the frame 10a, which provides the mounting location and support for the blade detection mechanism 80. The blade detection mechanism 80 is arranged above the rotary ring rail 10b and between the finished product unloading robot 70a and the pressing fan blade mechanism 60. The gasket detection mechanism 70b is mounted on the frame 10a, which provides the mounting location for the gasket detection mechanism 70b. The gasket detection mechanism 70b is positioned above the rotary ring rail 10b and between the gasket mounting mechanism 30 and the retaining ring mounting mechanism 40. The retaining ring detection mechanism 70d is mounted on the frame 10a, which provides the mounting location and support for the retaining ring detection mechanism 70d. The retaining ring detection mechanism 70d is positioned above the rotary ring rail 10b and between the retaining ring mounting mechanism 40 and the bearing mounting mechanism 50a. Therefore, the assembly reliability of the hydraulic fan finished product 200 is more effectively improved by using the gasket detection mechanism 70c, the retaining ring detection mechanism 70d, and the fan blade detection mechanism 80. It should be noted that the gasket detection mechanism 70b is used to detect whether the gasket 240 is missing, and the retaining ring detection mechanism 70d is used to detect whether the retaining ring 250 is missing. More specifically, see the description below.

[0036] like Figure 1 and Figure 2As shown, as an example, the bottom shell feeding conveyor line 10c extends along the length of the frame 10a, and partially extends into the frame 10a and is adjacent to the rotary track 10b, so as to facilitate the operation of the bottom shell loading robot 10d transferring the bottom shell 210 to the tooling seat 11; the fan blade feeding conveyor line 70b extends above the frame 10a along the length of the frame 10a, and partially extends out of the frame 10a in the direction of the bottom shell feeding conveyor line 10c, and is also separated from the bottom shell feeding conveyor line 10c in the width direction of the frame 10a; this design makes the hydraulic fan assembly machine 100 of the present invention smaller in the width direction of the frame 10a, thereby making the hydraulic fan assembly machine 100 of the present invention more adaptable to narrow and long occasions. Furthermore, regarding... Figure 1 and Figure 2 As an example, a first oil supply container 21 is provided next to the first oiling mechanism 20b, and the first oil supply container 21 continuously supplies oil to the first oiling mechanism 20b as needed; a second oil supply container 51 is provided next to the finished product unloading robot 70a, and the second oil supply container 51 continuously supplies oil to the second oiling mechanism 50c as needed. Furthermore, in conjunction with... Figure 4 As an example, the bottom shell loading robot 10d includes a linear transfer module 12 mounted on the frame 10a, a lifting driver 13 mounted on the linear transfer module 12, and a clamping assembly 14 mounted on the lifting driver 13, so that the bottom shell loading robot 10d can pick up and transfer the bottom shell 210 conveyed by the bottom shell feeding conveyor line 10c and place it on the tooling base 11 in a gripping manner. Specifically, as an example, both the bottom shell feeding conveyor line 10c and the fan blade feeding conveyor line 70b are conveyor lines. Obviously, depending on actual needs, the bottom shell feeding conveyor line 10c and the fan blade feeding conveyor line 70b can also be other conveyor lines; in addition, the lifting driver 13 can be a cylinder or hydraulic cylinder, but is not limited to this, and the clamping assembly 14 can be a pneumatic clamping assembly. It should be noted that since the first oiling mechanism 20b, the second oiling mechanism 50c, the first oil supply container 21 and the second oil supply container 51 are well known in the art, they will not be described in detail here.

[0037] like Figures 5 to 7As shown, as an example, the gasket loading mechanism 30 includes upper and lower frames 31 mounted on the frame 10a, a rotary drive 32 mounted on the upper and lower frames 31, a sliding frame 33 sliding upward and downward within the upper and lower frames 31, and a screw and nut transmission assembly 34 mounted between the sliding frame 33 and the rotary drive 32. The sliding frame 33 also passes downward through the upper and lower frames 31 and is provided with an adsorption mold head 35, a lower pressure plate 36, and a centering assembly 37; the lower pressure plate 36 is also provided with a clearance space 361, and each of the two opposite ends of the lower pressure plate 36 is equipped with an upper and lower sliding rod 38, which slides upward through the sliding frame 33, and the upper and lower sliding rods 38 are also fitted with a compression spring 39 that elastically abuts against the lower pressure plate 36 and the sliding frame 33; the adsorption mold head 35 is located between the upper and lower sliding rods 38, adsorbing... The mold head 35 is positioned vertically opposite the clearance space 361. The core-setting assembly 37 includes a telescopic actuator 371 and a core rod 372. Driven by the telescopic actuator 371, the core rod 372 can extend downward from the center of the adsorption mold head 35 or retract upward into the adsorption mold head 35. Therefore, during the gripping process of the pad 240, the telescopic actuator 371 drives the core rod 372 to extend downward from the adsorption mold head 35 and insert it into the center of the annular pad 240, thereby... The gasket 240 is carried away by the core rod 372; during the installation of the gasket 240, the rotary driver 32 drives the sliding frame 33, together with the adsorption mold head 35, the lower pressure plate 36, the upper and lower sliding rods 38, and the compression spring 39, to slide downwards via the lead screw and nut transmission assembly 34; since the lower pressure plate 36 is biased downwards relative to the adsorption mold head 35 under the action of the compression spring 39, the sliding frame 33 together with the adsorption mold head 35, the lower pressure plate 36, the upper and lower sliding rods 38, and the compression spring 39... During the downward sliding process, the lower pressure plate 36 first presses the bottom shell 210, and then the adsorption mold head 35 inserts the pad 240 into the bottom shell 210 from above. After the pad 240 is inserted into the bottom shell 210, under the push of the adsorption mold head 35 from above, the telescopic driver 371 drives the core rod 372 to retract upward into the adsorption mold head 35 and separate it from the pad 240, thereby facilitating the separation operation of the adsorption mold head 35 from the pad 240 inserted into the bottom shell 210. During the pressing of the lower pressure plate 36 against the bottom shell 210, the compression spring 39 is pushed upwards and compressed by the lower pressure plate 36, thus storing energy. Therefore, the compression spring 39, the lower pressure plate 36, the upper and lower sliding rods 38, and the centering assembly 37 work together with the adsorption mold head 35 to further ensure the reliability of the gasket loading mechanism 30 in loading the gasket 240 into the bottom shell 210. In addition, the cooperation of the rotary driver 32 and the lead screw and nut transmission assembly 34 can improve the accuracy of the gasket 240 loading. Furthermore, the more specific structure of the gasket loading mechanism 30 is described below.

[0038] Combination Figure 6 and Figure 8As an example, the adsorption head 35 has a vacuum channel 351 and a large shaft section 352 and a small shaft section 353 arranged coaxially from top to bottom. The outlet 3511 of the vacuum channel 351 is located on the large shaft section 352 to facilitate external air access by the operator; the inlet 3512 of the vacuum channel 351 is located on the end face 3531 of the small shaft section 353 away from the large shaft section 352 to facilitate the adsorption operation of the adsorption head 35 on the annular gasket 240; the core rod 372 can slide up and down in the vacuum channel 351, and the core rod 372 can extend downward into the small shaft section 353 or retract upward into the small shaft section 353 under the drive of the telescopic actuator 371; this design more effectively improves the reliability of the gripping and insertion of the retaining ring 240. For example, the telescopic actuator 371 can be, but is not limited to, a cylinder or a hydraulic cylinder; the rotary actuator 32 can be, but is not limited to, a motor. It should be noted that the large shaft segment 352 and the small shaft segment 353 are named according to their diameters; the one with the larger diameter is called the large shaft segment 352, and the one with the smaller diameter is called the small shaft segment 353.

[0039] like Figures 9 to 11As shown, as an example, the fastening mechanism 40 includes upper and lower frames 41 mounted on the frame 10a, a rotation drive 42 mounted on the upper and lower frames 41, a movable frame 43 slidingly disposed within the upper and lower frames 41, and a screw and nut transmission assembly 44 mounted between the movable frame 43 and the rotation drive 42. The movable frame 43 also extends downward through the upper and lower frames 41 and is equipped with a model head 45, a top pressure plate 46, and a centering module 47. The top pressure plate 46 is also provided with a clearance space 461. Each of the two opposite ends of the top pressure plate 46 is equipped with an upper and lower sliding column 48. The upper and lower sliding column 48 slides upward through the movable frame 43. The upper and lower sliding column 48 is also covered with a buffer spring 49 that elastically abuts against the top pressure plate 46 and the movable frame 43. The model head 45 is located between the upper and lower sliding columns 48 and is opposite to the clearance space 461 in the vertical direction. The centering module 47 includes an upper and lower actuator 471 and a centering rod 472. Under the drive of the upper and lower actuator 471, the centering rod 472 can extend downward from the center of the model head 45 or retract upward into the model head 45. Therefore, during the downward sliding process of the moving frame 43 together with the model head 45, the top pressure plate 46, the upper and lower sliding columns 48 and the buffer spring 49, the top pressure plate 46 first presses the bottom shell 210, and then the model head 45 inserts the buckle 250 into the bottom shell 210 from above. After the buckle 250 is inserted into the bottom shell 210, under the push of the model head 45 from above, the upper and lower drive 471 drives the centering rod 472 to retract upward into the model head 45 and separate it from the buckle 250, so as to facilitate the separation of the model head 45 from the buckle 250 inserted into the bottom shell 210. During the pressing of the top pressure plate 46 against the bottom shell 210, the buffer spring 49 is compressed upward by the top pressure plate 46 and is in an energy-storing state. Therefore, by using the buffer spring 49, the top pressure plate 46, the upper and lower sliding columns 48, and the core-fixing module 47 in conjunction with the model head 45, the reliability of the buckle-fitting mechanism 40 in installing the buckle 250 into the bottom shell 210 is further ensured. In addition, the cooperation of the rotary driver 42 and the lead screw and nut transmission assembly 44 can improve the accuracy of the buckle 250 installation. Furthermore, the more specific structure of the buckle-fitting mechanism 40 is described below.

[0040] Combination Figure 10 and Figure 12As an example, the model head 45 has an air passage 451 and a large shaft 452 and a small shaft 453 arranged coaxially from top to bottom. The inlet 4511 of the air passage 451 is located on the large shaft 452 to facilitate external air access for the operator. The end 453a of the small shaft 453 away from the large shaft 452 has four circumferentially spaced partition grooves 4531, which divide the end 453a into four conical blocks 4532. The outlet 4512 of the air passage 451 is located on the bottom surface 4533 of the partition grooves 4531 and is surrounded by the conical blocks 4532. The centering rod 472 is slidably placed in the air passage 451. Under the drive of the up and down actuators 471, the centering rod 472 can extend downward from the small shaft 453 or retract upward. The small shaft 453 is inserted into the small shaft body; this design reduces the contact area between the model head 45 and the retaining ring 250, and the reduced contact area facilitates the separation of the model head 45 and the retaining ring 250; furthermore, with the outlet 4512 of the air passage 451 located on the bottom surface 4533 of the partition groove 4531, and the centering rod 472 extending downward into the small shaft body 453 or retracting upward into the small shaft body 453 under the drive of the lifting drive 471, the airflow blown out from the outlet 4512 after the centering rod 472 retracts upward into the small shaft body 453 further increases the ease of separation between the model head 45 and the retaining ring 250, thereby effectively improving the reliability of the fastener 250 being assembled into the bottom shell 210. More specifically, in Figure 13 In this example, the end face 4534 of each conical block 4532 away from the bottom surface 4533 of the dividing groove 4531 is a flat surface perpendicular to the axial direction of the small shaft 453, to ensure reliable tight contact between the retaining ring 250 and each conical block 4532. It should be noted that, although... Figure 13 The diagram shows four dividing grooves 4531. Obviously, depending on actual needs, the number of dividing grooves 4531 can also be one, two, three, five, or more. Therefore, it is not limited to this. Figure 13 The above is a limited description; additionally, the lifting drive 471 may be a pneumatic or hydraulic cylinder, but is not limited to this; furthermore, the rotary drive 42 may be a motor, but is not limited to this. In addition, the large shaft 452 and the small shaft 453 are named according to their diameters, with the larger diameter being called the large shaft 452 and the smaller diameter being called the small shaft 453.

[0041] like Figure 14 As shown, as an example, the pressurized fan blade mechanism 60 includes a transverse drive 61 mounted on the frame 10a, a transverse base 62 mounted on the transverse drive 61, and each mounted on the transverse base 62 along the transverse direction of the transverse base 62 (see...). Figure 14The fan blade transfer module 63 and the fan blade pressing module 64, separated by double arrows, enable the pressing mechanism 60 to simultaneously grip the fan blades 230 conveyed from the fan blade feeding conveyor line 70b and simultaneously load the fan blades 230 into the base housing 210 and press the loaded fan blades 230 into the base housing 210, thus achieving high efficiency. For example, the transverse drive 61 can be, but is not limited to, a pneumatic or hydraulic cylinder.

[0042] like Figure 15 As shown, as an example, the fan blade detection mechanism 80 includes a downward pressure drive 81, a horizontal downward pressure ring 82, an adsorption pull head 83, and a lifting drive 84. The downward pressure drive 81 is mounted on the frame 10a. The horizontal downward pressure ring 82 is located below the downward pressure drive 81 and is mounted and connected to the downward pressure drive 81. The downward pressure drive 81 drives the horizontal downward pressure ring 82 to press or release the pressure base 210. The adsorption pull head 83 is vertically opposite to the space 821 enclosed by the horizontal downward pressure ring 82, so that the adsorption pull head 83 can enter downward from the space 821 enclosed by the horizontal downward pressure ring 82 and contact the fan blade 230. The lifting drive 84 is mounted on the frame 10a and is mounted and connected to the adsorption pull head 83, providing power for the vertical movement of the adsorption pull head 83. Therefore, when performing a tensile test on the fan blade 230 installed in the base housing 210, the base housing 210 is first pressed down by the horizontal pressure ring 82. Then, the lifting actuator 84 lifts the fan blade 230 upward through the suction head 83 to determine whether the fan blade 230 installed in the base housing 210 is qualified. For example, the pressure actuator 81 and the lifting actuator 84 can each be a pneumatic cylinder or a hydraulic cylinder, but are not limited to this.

[0043] Compared with the existing technology, the method utilizes a rotary ring rail 10b, multiple tooling seats 11 on the rotary ring rail 10b, a bottom shell feeding conveyor line 10c for conveying the bottom shell 210 pre-loaded with the stator 220 to the tooling seat 11, a bottom shell loading robot 10d that transfers the bottom shell 210 conveyed by the bottom shell feeding conveyor line 10c to the tooling seat 11, and a stator pressing machine arranged sequentially above the rotary ring rail 10b and assembled on the frame 10a along the length of the frame 10a. The design of the hydraulic fan assembly machine 100 includes a structure 20a, a first oiling mechanism 20b, a gasket mounting mechanism 30, a buckle mounting mechanism 40, a bearing mounting mechanism 50a, a bearing pressing mechanism 50b, a second oiling mechanism 50c, a fan blade mounting and pressing mechanism 60, and a finished product unloading robot 70a. Combined with the design of a fan blade feeding conveyor line 60a next to the fan blade mounting and pressing mechanism 60 for conveying fan blades 230 to the fan blade mounting and pressing mechanism 60, the automatic assembly and unloading of the finished product of the hydraulic fan is achieved. Furthermore, since the rotary track 10b mounted on the frame 10a can rotate in both the length and height directions of the frame 10a, this design reduces the space occupied by the hydraulic fan assembly machine 100 in the width of the frame 10a, thus making the hydraulic fan assembly machine 100 suitable for narrow and long spaces.

[0044] It is worth noting that arrow A in the attached diagram points in the length direction of frame 10a, arrow B points in the height direction of frame 10a, and arrow C points in the width direction of frame 10a. Furthermore, to accommodate different gaskets 240, retaining rings 250, and bearings 260, the gasket mounting mechanism 30, retaining ring mounting mechanism 40, and bearing mounting mechanism 50a are arranged in pairs. In addition, the stator pressing mechanism 20a and the bearing pressing mechanism 50b are of the same type, both driven by a motor via a lead screw and nut to move the pressing head in a loosening or pressing motion, and therefore will not be described further. Finally, since the bearing mounting mechanism 50a, the finished product unloading robot 70a, the gasket detection mechanism 70c, and the retaining ring detection mechanism 70d are well-known in the art, they will not be described further here.

[0045] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
