Description

Technical Field

[0001] This utility model relates to the field of centrifugal fan technology, specifically a centrifugal fan impeller chassis drilling device. Background Technology

[0002] The centrifugal fan impeller chassis, also known as the impeller base or hub disc, is the core structural component of the impeller that is directly connected to the drive shaft. It is used to fix the blades and transmit the motor torque, ensuring that the impeller maintains stability and balance when rotating at high speed. It is usually a circular or conical disc structure with a shaft hole in the center for installing the drive shaft and blade mounting holes or slots distributed on the edge.

[0003] However, the impeller chassis needs to be drilled in the middle during processing. Currently, the impeller chassis is usually drilled manually by hand using a drilling machine. However, manual drilling relies on visual positioning, which has limited accuracy. Furthermore, the impeller chassis may shift or move during drilling, resulting in poor drilling results. Therefore, we propose a centrifugal fan impeller chassis drilling device. Utility Model Content

[0004] The purpose of this utility model is to provide a device for drilling holes in the impeller chassis of a centrifugal fan.

[0005] To address the problems mentioned in the background art, this utility model provides the following technical solution: a centrifugal fan impeller chassis drilling device, comprising a worktable, a control plate fixed to one end of the worktable, a first motor mounted on one side of the worktable, a bidirectional screw mounted on one side of the first motor, movable plates mounted on both sides of the upper center of the worktable, a first clamping plate and a second clamping plate respectively fixed to one side of each movable plate, a fixed box fixed to one end of each movable plate, a second motor mounted on the upper end of one fixed box, a third motor mounted on the upper end of the other fixed box, screws mounted on the lower ends of both the second and third motors, movable blocks mounted inside each fixed box, friction plates fixed to the lower ends of each movable block, fixed blocks fixed on both sides of the upper end of the worktable, sliding rods fixed to the inner sides of each fixed block, a connecting plate fixed to the other end of the worktable, an electric telescopic rod mounted on the upper end of the connecting plate, a fourth motor mounted on the lower end of the electric telescopic rod, a fixed cylinder mounted on the lower end of the fourth motor, and a drill bit slidably mounted inside the fixed cylinder.

[0006] Preferably, the bidirectional screw passes through the movable plate and is threadedly connected to the movable plate, and the movable plate is slidably connected to the worktable.

[0007] Preferably, the screw passes through the movable block and is threadedly connected to the movable block, while the fixed box is slidably connected to the movable block.

[0008] Preferably, the slide rod passes through the first clamping plate and the second clamping plate, and the slide rod is slidably connected to both the first clamping plate and the second clamping plate.

[0009] Preferably, a limit block is fixed on one side of the inside of the fixed cylinder, multiple sets of connecting columns are fixed on one side of the fixed cylinder, a mounting plate is fixed on one side of the connecting column, a spring is provided on one side of the mounting plate, a sliding plate is installed on the connecting column, and an insertion post is fixed on one side of the sliding plate.

[0010] Preferably, the limiting block is slidably connected to the drill bit and engaged with the drill bit, and the spring is located between the mounting plate and the sliding plate.

[0011] Preferably, the connecting post passes through the slide plate and is slidably connected to the slide plate, and the insert post passes through the fixed cylinder and the drill bit, and is slidably connected to both the fixed cylinder and the drill bit.

[0012] Using the above technical solution, by placing the impeller chassis on the upper part of the worktable, and then starting the first motor, the first motor drives the moving plates on both sides through the bidirectional screw to push the first clamping plate and the second clamping plate closer to each other. At this time, the first clamping plate and the second clamping plate will push the impeller chassis on the upper part of the worktable, causing the impeller chassis to move towards the center position of the upper part of the worktable. When the first clamping plate and the second clamping plate are completely clamped on the impeller chassis, they stop. Then the impeller chassis will be directly below the drill bit. At this time, the second motor and the third motor are started, and the second motor and the third motor push the friction plate down through the screw and the moving block, so that the friction plate clamps and fixes the top of the impeller chassis. This allows the centrifugal fan impeller chassis drilling device to quickly position and clamp the impeller chassis, thereby accurately drilling the center position of the impeller chassis and ensuring that the impeller chassis does not move during the drilling process.

[0013] By using the above technical solution, the sliding plate is pulled so that it slides on the connecting column. Then the sliding plate will drive the insert column to slide out of the fixed cylinder, so that the fixing of the insert column to the drill bit is lost. Then the drill bit slides out of the fixed cylinder, thus completing the disassembly. Conversely, the installation is carried out, so that the centrifugal fan impeller chassis drilling device can load and unload the drill bit, which facilitates the quick replacement of the drill bit.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1:

[0021] Please see Figure 1-4This utility model provides a technical solution: a centrifugal fan impeller chassis drilling device, including a workbench 1, a control plate 2 fixed to one end of the workbench 1, a first motor 3 installed on one side of the workbench 1, a bidirectional screw 4 installed on one side of the first motor 3, movable plates 5 installed on both sides of the upper center of the workbench 1, a first clamping plate 6 and a second clamping plate 7 respectively fixed to one side of the two movable plates 5, a fixed box 8 fixed to one end of each of the two movable plates 5, a second motor 9 installed at the upper end of one fixed box 8, a third motor 10 installed at the upper end of the other fixed box 8, screws 11 installed at the lower ends of the second motor 9 and the third motor 10, movable blocks 12 installed inside the two fixed boxes 8, friction plates 13 fixed at the lower ends of the movable blocks 12, and the workbench 1... Fixed blocks 14 are fixed on both sides of the workbench 1. A sliding rod 15 is fixed on the inner side of the fixed block 14. A connecting plate 16 is fixed on the other end of the workbench 1. An electric telescopic rod 17 is provided on the upper end of the connecting plate 16. A fourth motor 18 is provided on the lower end of the electric telescopic rod 17. A fixed cylinder 19 is installed on the lower end of the fourth motor 18. A drill bit 20 is slidably installed inside the fixed cylinder 19. A bidirectional screw 4 passes through the moving plate 5 and is threadedly connected to the moving plate 5. The moving plate 5 is slidably connected to the workbench 1. A screw 11 passes through the moving block 12 and is threadedly connected to the moving block 12. A fixed box 8 is slidably connected to the moving block 12. A sliding rod 15 passes through the first clamping plate 6 and the second clamping plate 7 and is slidably connected to both the first clamping plate 6 and the second clamping plate 7.

[0022] Specifically, when drilling is required on the impeller chassis, the first motor 3 is reverse-started via the control board 2, causing the first motor 3 to drive the bidirectional screw 4 to rotate. As the bidirectional screw 4 rotates, it drives the two moving plates 5 to move away from each other. The process stops when the distance between the first clamping plate 6 and the second clamping plate 7 increases to a suitable position. Then, the impeller chassis is placed between the first clamping plate 6 and the second clamping plate 7. Next, the first motor 3 is forward-started via the control board 2, causing the first motor 3 to drive the first clamping plates 6 and the second clamping plate 7 to move closer together via the moving plates 5. At this point, the first clamping plates 6 and the second clamping plates 7 push the inner impeller chassis upwards onto the worktable 1. The device moves to the center position and stops when the first clamping plate 6 and the second clamping plate 7 completely clamp the impeller chassis. At this time, the impeller chassis will be located directly below the drill bit 20. Then, the control board 2 starts the second motor 9 and the third motor 10, which drive the screw 11 to rotate. The screw 11 then drives the moving block 12 to slide inside the fixed box 8, thereby pushing the friction plate 13 to clamp and fix the top of the impeller chassis. Then, the impeller chassis can be drilled. This allows the centrifugal fan impeller chassis drilling device to quickly position and clamp the impeller chassis, thereby accurately drilling the center position of the impeller chassis and preventing the impeller chassis from moving during the drilling process.

[0023] Example 2:

[0024] Please see Figure 1-4 This utility model provides a technical solution: a centrifugal fan impeller chassis drilling device, wherein a limiting block 21 is fixed on one side inside the fixed cylinder 19, multiple sets of connecting columns 22 are fixed on one side of the fixed cylinder 19, an mounting plate 23 is fixed on one side of the connecting column 22, a spring 24 is provided on one side of the mounting plate 23, a sliding plate 25 is installed on the connecting column 22, and an insert 26 is fixed on one side of the sliding plate 25; the limiting block 21 is slidably connected to the drill bit 20, and the limiting block 21 and the drill bit 20 are engaged, and the spring 24 is located between the mounting plate 23 and the sliding plate 25; the connecting column 22 passes through the sliding plate 25, and the connecting column 22 and the sliding plate 25 are slidably connected, and the insert 26 passes through the fixed cylinder 19 and the drill bit 20, and the insert 26 is slidably connected to both the fixed cylinder 19 and the drill bit 20.

[0025] Specifically, when the drill bit 20 needs to be replaced, the sliding plate 25 is pulled, causing it to slide on the connecting post 22. At this time, the sliding plate 25 will compress the spring 24, and simultaneously the sliding plate 25 will drive the insertion post 26 to slide out of the fixed cylinder 19 and the drill bit 20, thus removing the fixing of the drill bit 20 by the insertion post 26. Then, the drill bit 20 slides out of the fixed cylinder 19, and the new drill bit 20 slides into the fixed cylinder 19 and engages with the limiting block 21. Then, the sliding plate 25 is released, and under the elasticity of the spring 24, the sliding plate 25 pushes the insertion post 26 to insert into the fixed cylinder 19 and the limiting block 21, thereby completing the replacement. This allows the centrifugal fan impeller chassis drilling device to load and unload the drill bit 20, facilitating the quick replacement of the drill bit 20.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
