Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cross-flow fan processing technology, and in particular relates to a cross-flow fan housing flange riveting mechanism. Background Technology
[0002] A cross-flow fan, also known as a cross-flow fan, mainly consists of three parts: an impeller, an air duct, and a motor. The impeller material is generally aluminum alloy or engineering plastic. Aluminum alloy impellers are high in strength, lightweight, and heat-resistant, and can maintain stable operation for a long time without deformation; plastic impellers are injection molded and then ultrasonically welded, and are generally used in applications with lower speeds and larger diameters.
[0003] In the prior art, the riveting mechanism of the cross-flow fan housing is generally simple in structure, and is usually riveted by a riveting press. However, the existing riveting press does not have a clamping and fixing structure, and the operator needs to rivet by hand. Long-term operation can easily lead to high labor intensity for the operator and may also cause instability in the later stage. Therefore, a cross-flow fan housing flange riveting mechanism is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a flange riveting mechanism for the casing of a cross-flow fan, thereby solving the existing problems.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a flange riveting mechanism for a cross-flow fan housing, comprising a worktable and a placement plate. The worktable has an mounting groove on its upper surface, and a rotating shaft is rotatably mounted inside the mounting groove. The placement plate is mounted on the side of the rotating shaft, facilitating the flipping of the cross-flow fan housing so that its two ends are perpendicular to the rivet pins. This eliminates the need for subsequent re-clamping of the cross-flow fan housing, improving the efficiency of the device. A support rod is welded to one side of the upper surface of the placement plate, and a first mounting plate is welded to the upper surface of the support rod. A first hydraulic rod is mounted on the lower surface of the first mounting plate, and a first positioning plate is welded to the lower surface of the first hydraulic rod. Two second mounting plates are welded to the upper surface of the first positioning plate, and a second hydraulic rod is welded to one surface of each of the two second mounting plates. A second positioning plate is welded to one end of each of the two second hydraulic rods. This facilitates the fixing of the bottom and both ends of the cross-flow fan housing, improving the clamping stability of the cross-flow fan and facilitating subsequent riveting operations with the rivet pins. Manual clamping is unnecessary, reducing the workload of operators.
[0007] Furthermore, two second mounting plates are respectively disposed on both sides of the first hydraulic rod, a rotating motor is fixedly installed on the front surface of the worktable, one end of the rotating shaft extends to the outside of the worktable, and the output end of the rotating motor is fixedly connected to one end of the rotating shaft.
[0008] Furthermore, a first electric push rod is fixedly installed on each of the two opposing surfaces inside the mounting groove, and a snap-fit groove is opened on each of the two opposing surfaces of the placement plate. The positions of the two snap-fit grooves correspond to the positions of the two first electric push rods, and one end of each of the two first electric push rods is slidably connected to the inside of the two snap-fit grooves.
[0009] Furthermore, support columns are welded to the periphery of the lower surface of the workbench, and second electric push rods are installed on the periphery of the upper surface of the workbench. A mounting block is welded to the upper surface of the two second electric push rods.
[0010] Furthermore, each of the two mounting blocks has a sliding groove on its opposite surface, and a lead screw is rotatably installed inside each of the two sliding grooves. A drive motor is fixedly installed on one surface of each of the two mounting blocks, and one end of each lead screw extends to the outside of the two mounting blocks respectively.
[0011] Furthermore, the output ends of the two drive motors are respectively fixedly connected to one end of the two lead screws, and each of the two lead screws has a movable block screwed to its peripheral side, and the two movable blocks are slidably connected to the two slide grooves respectively.
[0012] Furthermore, an electric slide rail is fixedly installed between the two movable blocks, and a sliding block is slidably installed on the periphery of the electric slide rail.
[0013] Furthermore, a stamping cylinder is bolted to one surface of the sliding block, and a rivet is installed on the piston end of the stamping cylinder.
[0014] This utility model has the following beneficial effects:
[0015] This utility model, through the structure of a first hydraulic rod, a first positioning plate, a second hydraulic rod, and a second positioning plate, facilitates the fixation of the bottom and both ends of the cross-flow fan housing, improves the clamping stability of the cross-flow fan, and facilitates subsequent riveting operations with rivets, eliminating the need for manual clamping and reducing the workload of operators.
[0016] This invention, through its rotating shaft, placement plate, and drive motor structure, facilitates the flipping of the cross-flow fan housing, ensuring that both ends of the fan are perpendicular to the rivet pins. This eliminates the need for subsequent re-clamping of the cross-flow fan housing, thereby improving the working efficiency of the device.

The upper surface of the worktable 1 has an installation groove 2, inside which a rotating shaft 3 is rotatably mounted. The placement plate 4 is installed on the side of the rotating shaft 3, facilitating the flipping of the cross-flow fan housing so that its two end planes are perpendicular to the rivet pins 23, eliminating the need for subsequent re-clamping of the cross-flow fan housing and improving the working efficiency of the device. A support rod 6 is welded to one side of the upper surface of the placement plate 4, and a first mounting plate 7 is welded to the upper surface of the support rod 6. A first hydraulic rod 8 is mounted on the lower surface of a mounting plate 7. A first positioning plate 9 is welded to the lower surface of the first hydraulic rod 8. Two second mounting plates 10 are welded to the upper surface of the first positioning plate 9. A second hydraulic rod 11 is welded to one surface of each of the two second mounting plates 10. A second positioning plate 12 is welded to one end of each of the two second hydraulic rods 11. This facilitates the fixation of the bottom and both ends of the cross-flow fan housing, improves the clamping stability of the cross-flow fan, and facilitates subsequent riveting operations with rivets 23. No manual clamping is required, reducing the workload of operators.
[0028] Two second mounting plates 10 are respectively set on both sides of the first hydraulic rod 8. A rotating motor 5 is fixedly installed on the front surface of the worktable 1. One end of the rotating shaft 3 extends to the outside of the worktable 1, and the output end of the rotating motor 5 is fixedly connected to one end of the rotating shaft 3.
[0029] The first electric push rod 14 is fixedly installed on both opposite surfaces inside the mounting slot 2. The two opposite surfaces of the placement plate 4 are provided with snap-fit slots 13. The positions of the two snap-fit slots 13 correspond to the positions of the two first electric push rods 14. One end of the two first electric push rods 14 is slidably connected to the inside of the two snap-fit slots 13 respectively.
[0030] Support columns 24 are welded to the lower surface of the workbench 1, and second electric push rods 15 are installed on the upper surface of the workbench 1. Mounting blocks 16 are welded to the upper surfaces of the two second electric push rods 15.
[0031] Each of the two mounting blocks 16 has a sliding groove on its opposite surface. A lead screw 17 is rotatably installed inside each of the two sliding grooves. A drive motor 18 is fixedly installed on one surface of each of the two mounting blocks 16. One end of each lead screw 17 extends to the outside of the two mounting blocks 16.
[0032] The output ends of the two drive motors 18 are fixedly connected to one end of the two lead screws 17 respectively. The two lead screws 17 are each screwed with a moving block 19 on their circumferential side. The two moving blocks 19 are slidably connected to the two slides respectively.
[0033] An electric slide rail 20 is fixedly installed between the two movable blocks 19, and a sliding block 21 is slidably installed on the side of the electric slide rail 20.
[0034] A stamping cylinder 22 is bolted to one surface of the sliding block 21, and a rivet 23 is installed on the piston end of the stamping cylinder 22.
[0035] Please see Figures 1-4 As shown, this utility model is a flanged riveting mechanism for a cross-flow fan housing. Its usage is as follows: First, the cross-flow fan housing is placed above the placement plate 4 from the other side of the support rod 6. At this time, the first hydraulic rod 8 is activated to drive the first positioning plate 9 to descend and fix it to the bottom of the cross-flow fan housing. Since the cross-flow fan housing has a volute shape, the two second hydraulic rods 11 are then driven to push the two second positioning plates 12 to abut against the two ends inside the cross-flow fan housing, preventing slippage during subsequent flipping and providing support when riveting the two ends of the cross-flow fan housing. Then, the drive motor 18 and electric slide rail 20 are activated to move the moving block 19 and sliding block 21, causing... The stamping cylinder 22 and the rivet 23 move flexibly in the X and Y directions. Then, the second electric push rod 15 is activated to adjust the position of the stamping cylinder 22 and the rivet 23 to perform riveting operations on the bottom of the cross-flow fan housing. When it is necessary to perform riveting operations on both ends of the cross-flow fan housing, the stamping cylinder 22 is first lifted by the second electric push rod 15, and then the two first electric push rods 14 are activated to disengage it from the snap-fit groove 13. Then, the rotary motor 5 is activated to drive the rotating shaft 3 and the placement plate 4 to rotate, so that the planes at both ends of the cross-flow fan housing are perpendicular to the rivet 23. Then, the riveting operation is performed. There is no need to re-clamp the cross-flow fan housing later, which improves the working efficiency of the device.
