Description

Technical Field

[0002] In the production and manufacturing of fans, the drive motor, fan blades and other components are installed in the fan casing for assembly. When the fan casing is processed, it is necessary to punch and cut the fan casing. In order to achieve better cutting quality and high precision of the punching, laser cutting is often used. The fan casing of some products has a cylindrical structure after molding, and special fixtures and positioning and loading mechanisms are required for clamping. In order to reduce the deformation of the fan casing due to external force squeezing due to clamping during punching and cutting.

[0003] The patent with publication number: CN118744290A discloses a laser drilling device for fan casing processing, including a processing fixed table; a control panel is fixedly connected to the front of the processing fixed table; the cutting laser knife is installed on the processing fixed table; the waste tray is slidably connected to the right side of the processing fixed table; it has a mechanism for positioning workpieces with special structures, and at the same time has the function of driving the workpiece to orient and rotate at a constant speed, and adjusts the processing area of ​​the workpiece to always be within the effective range of the laser cutting device, which solves the problem that the clamping force of the conventional fan casing laser cutting equipment is too large, which causes the cylindrical structure of the fan casing to be squeezed and deformed, and after the fan casing is positioned once, it is not convenient to perform rotation reversing, and the use of laser cutting equipment with large displacement reversing for processing will increase production costs, and the processing error will increase as the cutting equipment moves too much.

[0004] However, the above invention still has some shortcomings in actual use: 1. Generally, a flanging process is required before punching holes in the fan casing, and the above mechanism for clamping the fan casing is not suitable for the fan casing that has been flanging; 2. The above invention does not process and collect the fragments that fall after laser punching, so that the fragments are very easy to scatter or get stuck in the gaps of the mechanism; 3. The above inventor needs to manually carry the fan casing to the clamping mechanism; 4. In the prior art, the fan casing needs to be flipped over to achieve punching on both sides, which is very inconvenient.

[0022] Then the displacement telescopic rod 50 contracts, driving the connecting rod 181, the connecting plate 16, the support frame 7 and the two supporting wheels 8 to move upward. During the upward movement of the two supporting wheels 8, the fan casing body 19 will be automatically positioned in the center. Before the top end of the connecting rod 181 collides with the mounting slide 17, the fan casing body 19 has been completely supported by the two supporting wheels 8, so that the center of the rotating motor 16 is at the same height as the center of the fan casing body 19.

[0023] Among them, the internal positioning mechanism 202 includes a limit ring 11, an outer limit cavity 20, a limit slide 21, a fixed rod 22, a first slider 23, a connecting rod 26 and an internal slider 27.

[0024] In this embodiment, when the displacement telescopic rod 50 continues to move upward, the connecting rod 181 will move upward against the mounting slide 17 so that the connecting rod 26 will be limited by the limiting slide 21, thereby driving the internal slide 27, the fixed plate 28, the cross slide 12, the positioning plate 9, the four clamping rods 29, and the four rubber clamping blocks 10 to extend into the interior of the fan casing body 19. Since the four rubber clamping blocks 10 are all in the positioning plate 9 at this time, the rubber clamping blocks 10 are deep into the fan casing body 19 and there is no contact between the two.

[0026] Among them, the clamping mechanism 303 also includes a cross slider 12, a rotating shaft 25, a first rack 30, a first gear 31, a second gear 32 and a first gear rod 33.

[0027] In this embodiment, when the displacement telescopic rod 50 drives the connecting plate 6 to move up to the maximum limit, the first gear 31 engages with the first rack 30, thereby driving the second gear 32 to rotate by rotating the shaft 25, and the second gear 32 drives the first gear rod 33 and the cross slider 12 to extend, and the four clamping rods 29 extend from the positioning plate 9 toward the surroundings along the inclined surface of the cross slider 12, so that the rubber clamping block 10 clamps the inner wall of the fan casing body 19.

[0028] Among them, the outer wall of the mounting slide 17 is fixedly connected with a synchronous displacement rod 180, the outer wall of the synchronous displacement rod 180 is fixedly connected with a side limit plate 36, the inner wall of the side limit plate 36 is rotatably connected with a side rotating wheel 2 34 and a side rotating wheel 1 35, and the side rotating wheel 1 35 is arranged above the side rotating wheel 2 34.

[0029] Among them, the synchronous collection mechanism 404 includes a sliding shaft 24, a mounting frame 37, a third gear 39, an outer limit shell 38, a fourth gear ring 40, an internal telescopic rod 41 and a support block 42. The mounting frame 37 is fixedly connected to the side wall of the side limit plate 36, the third gear 39 is rotatably connected to the mounting frame 37, the third gear 39 is rotatably connected to the side rotating wheel 35 through a one-way bearing, the outer limit shell 38 is rotatably connected to the side wall of the side limit plate 36, the fourth gear ring 40 is fixedly connected to the outer wall of the outer limit shell 38, the outer limit shell 38 is meshed with the third gear 39, the internal telescopic rod 41 is slidably connected to the outer limit shell 38 through the sliding shaft 24, the internal telescopic rod 41 is slidably connected to the inner wall of the side limit plate 36, and the support block 42 is fixedly connected to the end of the internal telescopic rod 41.

[0030] Among them, the synchronous collection mechanism 404 also includes a material guide trough 43, a suction cup 44, a mounting rod 45, a stripping frame 46, a fixed rod 47, a first spring 48, a collection box 13 and a second spring 49. The fixed rod 47 is fixedly connected to the internal telescopic rod 41, the second spring 49 is fixedly connected between the internal telescopic rod 41 and the side limit plate 36, the mounting rod 45 is slidably connected to the inner wall of the fixed rod 47, the first spring 48 is fixedly connected between the mounting rod 45 and the fixed rod 47, the stripping frame 46 surrounds the outer side of the mounting rod 45, the stripping frame 46 is fixedly connected to the side limit plate 36, the suction cup 44 is fixedly connected to the mounting rod 45, the material guide trough 43 is arranged below the stripping frame 46, the collection box 13 is fixedly connected to the material guide trough 43, the collection box 13 is fixedly connected to the synchronous displacement rod 180, and two synchronous collection mechanisms 404 are provided, and the two synchronous collection mechanisms 404 are symmetrically distributed on both sides of the side limit plate 36.

[0031] In this embodiment, after clamping, drilling can be performed, and the rotating motor 16 slowly rotates and stops. When it stops, the two first shaft rods 4 extend out and the flanges on both sides of the fan housing body 19 are drilled. Due to the action of the synchronous displacement rod 180, the connecting rod 181 and the side limit plate 36 are moved up together with the fan housing body 19. Therefore, when the fan housing body 19 rotates, the side rotating wheel 2 34 and the side rotating wheel 1 35 will rotate together due to friction. At the same time, the setting is as follows: Fig.10 In the direction shown, the fan casing body 19 rotates clockwise with the side rotating wheel 35, and the side rotating wheel 35 is now locked with the third gear 39 through a one-way bearing, so that the third gear 39 rotates clockwise with the side rotating wheel 35, so that the third gear 39 drives the outer limit shell 38 to rotate counterclockwise through the fourth gear ring 40, and drives the internal telescopic rod 41 to retract through the sliding shaft 24 and the arc groove to avoid affecting the rotation of the fan casing body 19.

[0032] When the fan casing body 19 is stationary, due to the reset force of the second spring 49, the internal telescopic rod 41 extends out of the sliding shaft 24 to drive the outer limit shell 38 to reverse, thereby driving the fourth gear ring 40 and the third gear 39 to rotate, but due to the action of the one-way bearing, the third gear 39 will not drive the side rotating wheel 35 to rotate. At this time, the support block 42 is close to the outer wall of the fan casing body 19 at the flange, providing it with good support. At the same time, the suction cup 44 is tightly adsorbed on the punching place due to the action of the fixing rod 47. The suction cup 44 is set to be smaller than the punching range, so when the punching is completed, the fragments will not fall off, but will be adsorbed by the suction cup 44. When the fan casing body 19 rotates again, the internal telescopic rod 41 retracts the fragments on the suction cup 44 and is blocked by the stripping frame 46, so that the fragments fall into the guide trough 43 and are collected by the collection box 13.

[0033] The specific working principle and method of use of the present invention are explained in detail below: When in use, a worker pushes the fan casing body 19 onto the floor 3 in a rolling form, and sets the width of the floor 3 to be smaller than the width of the fan casing body 19, so that the floor 3 can be stuck in the two flanges of the fan casing body 19, and then the loading motor 15 rotates slowly, driving the floor 3 to be slowly lifted, so that the fan casing body 19 slowly rolls to the inside of the main frame 1, and the side has a side rotating wheel 2 34 and a side rotating wheel 1 35 to limit the fan casing body 19, and the side rotating wheel 2 34 and the side rotating wheel 1 35 can be made of rubber material, which will not damage the outer wall of the fan casing body 19 and has a certain friction.

[0034] Then, the displacement telescopic rod 50 contracts, driving the connecting rod 181, the connecting plate 16, the support frame 7 and the two supporting wheels 8 to move upward. During the upward movement of the two supporting wheels 8, the fan casing body 19 will be automatically positioned at the center position. Before the top of the connecting rod 181 collides with the mounting slide 17, the fan casing body 19 has been completely supported by the two supporting wheels 8, so that the center of the rotating motor 16 is at the same height as the center of the fan casing body 19. Then, when the displacement telescopic rod 50 continues to move upward, the connecting rod 181 will move upward against the mounting slide 17 so that the connecting rod 26 will be limited by the limiting slide 21, thereby driving the internal slide 27, the fixed plate 28, the cross slide 12, the positioning plate 9, the four clamping rods 29, and the four rubber clamping blocks 10 to extend into the interior of the fan casing body 19. Since the four rubber clamping blocks 10 are all in the positioning plate 9 at this time, the rubber clamping blocks 10 penetrate into the fan casing body 19 without any contact between the two.

[0035] When the displacement telescopic rod 50 drives the connecting plate 6 to move up to the maximum limit, the first gear 31 meshes with the first rack 30, thereby driving the second gear 32 to rotate by rotating the shaft 25, and the second gear 32 drives the first gear rod 33 and the cross slider 12 to extend, and the four clamping rods 29 extend from the positioning plate 9 toward the surroundings along the inclined surface of the cross slider 12, so that the rubber clamping block 10 clamps the inner wall of the fan casing body 19.

[0036] After clamping, drilling can be carried out, and the rotating motor 16 slowly rotates and stops. When it stops, the two first shaft rods 4 extend out and the flanges on both sides of the fan housing body 19 are drilled. Due to the action of the synchronous displacement rod 180, the connecting rod 181 and the side limit plate 36 move up together with the fan housing body 19. Therefore, when the fan housing body 19 rotates, the side rotating wheel 2 34 and the side rotating wheel 1 35 will rotate together due to friction. At the same time, the setting is as follows: Fig.10 In the direction shown, the fan casing body 19 rotates clockwise with the side rotating wheel 35, and the side rotating wheel 35 is now locked with the third gear 39 through a one-way bearing, so that the third gear 39 rotates clockwise with the side rotating wheel 35, so that the third gear 39 drives the outer limit shell 38 to rotate counterclockwise through the fourth gear ring 40, and drives the internal telescopic rod 41 to retract through the sliding shaft 24 and the arc groove to avoid affecting the rotation of the fan casing body 19.

[0037] When the fan casing body 19 is stationary, due to the reset force of the second spring 49, the internal telescopic rod 41 extends out of the sliding shaft 24 to drive the outer limit shell 38 to reverse, thereby driving the fourth gear ring 40 and the third gear 39 to rotate, but due to the action of the one-way bearing, the third gear 39 will not drive the side rotating wheel 35 to rotate. At this time, the support block 42 is close to the outer wall of the fan casing body 19 at the flange, providing it with good support. At the same time, the suction cup 44 is tightly adsorbed on the punching place due to the action of the fixing rod 47. The suction cup 44 is set to be smaller than the punching range, so when the punching is completed, the fragments will not fall off, but will be adsorbed by the suction cup 44. When the fan casing body 19 rotates again, the internal telescopic rod 41 retracts the fragments on the suction cup 44 and is blocked by the stripping frame 46, so that the fragments fall into the guide trough 43 and are collected by the collection box 13.

[0038] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
