Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0035] For the riveting device of the flow fan assembly machine, please refer to [link / reference]. Figure 1-3 As shown, it includes: a bracket 100, multiple sets of riveting rollers 200, a drive plate 300, a first drive assembly 400, and a second drive assembly 500.

[0036] The bracket 100 is used as a carrier, mainly to provide support, supporting at least the multiple sets of riveting rollers 200 and the drive plate 300. The bracket 100 is provided with a left support plate 110 and a right support plate 120 distributed from left to right. The multiple sets of riveting rollers 200 are installed between the left support plate 110 and the right support plate 120. In this embodiment, three sets of riveting rollers 200 are provided, arranged in a triangular pattern.

[0037] Continue as Figure 1 As shown, the left support plate 110 and the right support plate 120 are provided with support rods 140, which fix the position between the left support plate 110 and the right support plate 120.

[0038] Three sets of riveting rollers 200 are installed parallel to each other on the bracket 100. Each set of riveting rollers 200 is equipped with a riveting head 210. The two ends of the riveting rollers 200 pass through the left support plate 110 and the right support plate 120 respectively. When the large flow impeller is riveted, it is located between the three sets of riveting rollers 200 and the large flow impeller is riveted by the riveting rollers 200.

[0039] The drive plate 300 is installed on the outside of the left support plate 110 and the right support plate 120. The two ends of the riveting roller 200 pass through the left support plate 110 and the right support plate 120 and are connected to the drive plate 300. The drive plate 300 is provided with an arc-shaped track groove 310. The two ends of at least one set of riveting rollers 200 are respectively limited to the track groove 310 and can move within the track groove 310.

[0040] like Figure 3As shown, in this embodiment, the three sets of riveting rollers 200 are all limited by the track grooves 310 on the drive plate 300, and the drive plate 300 is provided with track grooves 310 for each set of riveting rollers 200, and the three track grooves 310 are not connected.

[0041] In order for the riveting roller 200 to move normally along the track groove 310, the left support plate 110 and the right support plate 120 are respectively provided with clearance grooves 130, which avoid the riveting roller 200 so that it can move; the clearance grooves 130 and the track groove 310 partially overlap.

[0042] The first drive assembly 400 drives the drive plate 300 to move, thereby causing the riveting roller 200 to move in the track groove 310. When the first drive assembly 400 drives the drive plate 300 to move forward, the riveting roller 200 moves forward along the track groove 310, and multiple sets of riveting rollers 200 converge to clamp the workpiece. When the first drive assembly 400 drives the drive plate 300 to move in the opposite direction, the multiple sets of riveting rollers 200 move in the opposite direction along the track groove 310, and the multiple sets of riveting rollers 200 move away from each other to release the workpiece.

[0043] The second drive assembly 500 drives the riveting roller 200 to rotate in order to rivet the workpiece.

[0044] In order to enable the riveting roller 200 to move smoothly in the track groove 310, rollers are provided at both ends of the riveting roller 200 to assist the riveting roller 200 in moving along the track groove 310.

[0045] In one embodiment, the drive plate 300 is provided with an arc-shaped rack 320, and the track groove 310 is arc-shaped; for example Figure 1 and Figure 3 As shown, the outer edge of the drive plate 300 is provided with an arc-shaped rack 320, and the first drive assembly 400 includes: a first motor 410 and a first meshing gear 420 that meshes with the arc-shaped rack 320;

[0046] The first motor 410 drives the first meshing gear 420 to rotate. Through the cooperation of the first meshing gear 420 and the arc rack 320, the drive plate 300 is driven to rotate. Then, with the cooperation of the clearance groove 130 and the track groove 310, the riveting roller 200 moves. When moving, the three sets of riveting rollers 200 move closer to each other or further apart.

[0047] In addition, the first motor 410 can directly drive the first meshing gear 420 to rotate, or it can indirectly drive the first meshing gear 420 to rotate.

[0048] In order to achieve synchronous movement of both ends of the riveting roller 200, two first motors 410 can be set up, each first motor 410 driving a first meshing gear 420, thereby driving the riveting roller 200 to move.

[0049] It is also possible that, for example Figure 3 As shown, the first drive assembly 400 further includes a connecting rod 430, which is mounted on the bracket 100 and parallel to the riveting roller 200; the two ends of the connecting rod 430 are respectively provided with the first meshing gear 420, and the drive plates 300 located at both ends of the riveting roller 200 respectively mesh with one of the first meshing gears 420, so that the two ends of the riveting roller 200 move synchronously.

[0050] Furthermore, the output shaft of the first motor 410 is equipped with a first transmission wheel 411; the connecting rod 430 is equipped with a second transmission wheel 431, and the first transmission wheel 411 and the second transmission wheel 431 mesh with each other.

[0051] In one implementation, such as Figure 2 As shown, the second drive assembly 500 includes: a second motor 510, a belt drive assembly 520, and multiple sets of oscillating gears 530; the second motor 510, the belt drive assembly 520, and the multiple sets of oscillating gears 530 drive the riveting roller 200 to rotate, and the oscillating gears 530 oscillate as the riveting roller 200 moves along the track groove 310.

[0052] The oscillating gear set 530 includes: a swing arm 531 and a plurality of meshing transmission wheels 532 disposed on the swing arm 531, wherein one transmission wheel a532a is fixed to one end of the riveting roller 200; one transmission wheel b532b meshes with the transmission wheels 532 of other oscillating gear sets 530, or one transmission wheel b532b meshes with a gear on a belt drive set 520 to achieve transmission.

[0053] Specifically, such as Figure 2 As shown, the belt drive assembly 520 includes two drive wheels and a belt wound around the drive wheels. The second motor 510 drives the belt drive assembly 520 to run. Multiple sets of oscillating gear sets 530 mesh with each other, and at least one set of oscillating gear sets 530 is connected to the belt drive assembly 520 and drives it, ultimately driving the riveting roller 200 to rotate.

[0054] In one embodiment, the riveting roller 200 further includes a rod 220 on which riveting heads 210 are evenly distributed. The number of riveting heads 210 and the spacing between multiple riveting heads 210 are determined according to the number of fixing rings that need to be riveted on the large-scale flow impeller.

[0055] The large-scale flow impeller includes multiple blades and a fixing ring connecting the multiple blades. The fixing ring is annular, and the blades are inserted into the fixing ring. The number of rivet heads 210 and the spacing between the multiple rivet heads 210 are set according to the number of fixing rings on the large-scale flow impeller.

[0056] In use, the three sets of riveting rollers 200 are far apart. The large flow impeller is installed between the three sets of riveting rollers 200. Then, the first drive assembly 400 runs in the forward direction. The first motor 410 drives the connecting rod 430 to rotate, and at the same time drives the first meshing gear 420 to rotate, so as to drive the drive plate 300 to rotate. When rotating, the three sets of riveting rollers 200 move closer to each other to clamp the large flow impeller.

[0057] Then, the second drive assembly 500 operates, driving the three sets of riveting rollers 200 to rotate. During the rotation, the large flow fan wheel rotates, and at the same time, the riveting head 210 performs the riveting operation between the fixed ring and the blade.

[0058] Finally, after the riveting is completed, the second drive assembly 500 stops running, and the first drive assembly 400 runs in reverse to drive the drive plate 300 to move in the opposite direction, so that the three sets of riveting rollers 200 move away from each other, loosen the large flow impeller after riveting, and then take out the large flow impeller.

[0059] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
