Description
Technical Field
[0001] The utility model relates to the technical field of clamping tooling, in particular to a clamping tooling for processing a centrifugal fan. Background Art
[0002] At present, centrifugal fans are mainly composed of: impellers, casings, couplings, shafts and bases. When processing centrifugal fans, they need to be painted. At this time, the centrifugal fans need to be clamped and fixed. The centrifugal fans are irregular in shape, and multiple clamps are required to cooperate with each other to clamp the two planar side walls of the centrifugal fans to ensure the stability of the clamping. An air inlet is installed on one planar side wall of the centrifugal fan, so the clamps can only be clamped on both sides of the air inlet. The existing clamping tooling fixes the clamping point position of the centrifugal fan, but the sizes of centrifugal fans are different. When the size of the centrifugal fan changes, the size of the air inlet of the centrifugal fan also changes, which causes the position of the clamping point to change, resulting in the inability of the existing clamping tooling to clamp firmly.
[0003] Therefore, we designed a clamping tool for centrifugal fan processing. Utility Model Content

DETAILED DESCRIPTION
[0021] Reference Figure 1-Figure 5 , a clamping tool for processing a centrifugal fan, comprising a workbench 1 and a casing 3 placed on the workbench 1, a supporting plate 12 and a first connecting frame 4 are provided on the workbench 1, a butt plate 13 is provided on the supporting plate 12, the casing 3 is butted against the butt plate 13, the butt plate 13 is relatively large in size, ensuring that the force point of the butt plate 13 on the casing 3 is located at the center position of the casing 3, a second connecting frame 5 is provided above the first connecting frame 4, two electric hydraulic cylinders 11 are provided between the casing 3 and the second connecting frame 5, and a clamping plate is provided on the output end of the electric hydraulic cylinder 11, when in use, the electric hydraulic cylinder 11 is started to push the clamping plate against the casing 3, and the casing 3 is fixedly clamped by cooperating with the butt plate 13 and the clamping plate, and the position of the clamping plate is changed to ensure that the clamping plate and the butt plate 13 clamp the casing 3 in the center position, and two first sliders 18 and second sliders 19 for changing the clamping position of the clamping plate on the casing 3 are respectively provided in the first connecting frame 4 and the second connecting frame 5.
[0022] Reference Figure 3 As shown, the first connection frame 4 is rotatably connected to the second screw rod 17, the second screw rod 17 is threadedly connected to the first slider 18, and the two first sliders 18 are each provided with a connecting rod 10, and the two ends of the two connecting rods 10 are rotatably connected to the first slider 18 and the second connection frame 5 through connecting pieces;
[0023] Reference Figure 5 As shown, the connecting member includes a pillow block and a rotating shaft. The pillow blocks are respectively fixed on the first slider 18 and the second connecting frame 5, and the ends of the connecting rod 10 are rotatably connected to the pillow blocks through the rotating shaft.
[0024] When in use, rotating the second screw rod 17 drives the two first sliders 18 to move toward each other, and the first slider 18 drives the second connecting frame 5 to rise and fall by rotating the connected connecting rod 10, thereby driving the two clamping plates to rise and fall. When the two first sliders 18 approach each other, the connecting rod 10 rotates and unfolds, gradually tends to be vertical, and at this time, the second connecting frame 5 can be driven to rise. When the two first sliders 18 move away from each other, the connecting rod 10 rotates and folds, gradually tends to be horizontal, and at this time, the second connecting frame 5 can be driven to descend.
[0025] A first screw rod 16 is rotatably connected in the second connecting frame 5, two second sliders 19 are threadedly connected to the first screw rod 16, and two electric hydraulic cylinders 11 are fixedly connected to the second sliders 19. When in use, the first screw rod 16 is rotated to drive the two second sliders 19 to move toward each other, and the second sliders 19 drive the two clamping plates to move, thereby adjusting the distance between the two clamping plates, thereby changing the position of the clamping point, and achieving the effect of clamping and fixing centrifugal fans of different sizes.
[0026] Reference Figure 3 and Figure 4 As shown, a first connection block 6 and a second connection block 7 are respectively disposed on one side of the first connection frame 4 and the second connection frame 5 , and a second bevel gear set 15 and a first bevel gear set 14 are respectively disposed in the first connection block 6 and the second connection block 7 .
[0027] The second bevel gear set 15 includes two meshing first bevel gears, the second screw rod 17 is coaxially fixed with the first bevel gear, a cross rod 8 is fixedly connected to the first bevel gear, the cross rod 8 passes through the first connecting block 6 and the second connecting block 7, the first bevel gear set 14 includes two meshing second bevel gears, the first screw rod 16 is coaxially fixed with the second bevel gear, the cross rod 8 slides through the second bevel gear, the first bevel gear is rotated during use, the first bevel gear drives the second bevel gear to rotate through the cross rod 8, the second bevel gear slides coaxially with the cross rod 8, and does not affect the second connecting frame 5 and the first bevel gear. The lifting and lowering of the two connecting blocks 7 only requires one driving force to simultaneously adjust the distance and height between the two clamping plates, saving the use cost. It should be noted that the threads of the first screw rod 16 and the second screw rod 17 are arranged oppositely. When the first screw rod 16 and the second screw rod 17 rotate at the same time, the moving directions of the two second sliders 19 and the first slider 18 are opposite. The purpose is to expand the distance between the two clamping plates while adjusting the height of the clamping plates. As the size of the centrifugal fan increases, the diameter of the air inlet will also increase, so it is necessary to adjust the distance and height between the two clamping plates at the same time.
[0028] Reference Figure 1As shown, a motor 9 and a plurality of brackets 2 are provided at the bottom of the workbench 1. The brackets 2 are provided to facilitate the placement of the workbench 1. The output end of the motor 9 extends into the first connecting block 6 and is coaxially fixed with the first bevel gear. When in use, the motor 9 is started to drive the second bevel gear group 15 and the first bevel gear group 14 to rotate, thereby driving the second screw rod 17 and the first screw rod 16 to rotate, so as to adjust the position of the clamping plate. It should be noted that the specific model and specifications of the motor 9 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0029] The working principle of the utility model is as follows:
[0030] Start the motor 9 to drive the second bevel gear group 15 to rotate. The rotating second bevel gear group 15 drives the second screw rod 17 to rotate. The second screw rod 17 drives the two first sliders 18 to move toward each other. The first slider 18 drives the second connecting frame 5 to rise and fall through the rotating connecting rod 10, thereby driving the two clamping plates to rise and fall. The rotating second bevel gear group 15 drives the first bevel gear group 14 to rotate through the cross rod 8. The second bevel gear slides coaxially with the cross rod 8 and does not affect the lifting of the second connecting frame 5. The second bevel gear group 14 drives the first screw rod 16 to rotate. Rotating the first screw rod 16 drives the two second sliders 19 to move toward each other. The second slider 19 drives the two clamping plates to move, thereby adjusting the distance between the two clamping plates, thereby changing the position of the clamping point, and achieving the effect of clamping and fixing centrifugal fans of different sizes.
