[0002] In the field of centrifugal blower manufacturing, the machining precision and efficiency of the impeller blade directly affect the overall performance, running stability and production cost of the centrifugal blower. As the core component of the centrifugal blower, the impeller blade has relatively strict design requirements, especially the geometric parameters such as the upper end angle and taper of the blade, which play a decisive role in the subsequent gas dynamic performance of the blower. When facing the machining of the impeller blade, the thickness of the blade itself is small, and vibration phenomenon is prone to occur during the machining process. This is because the blade is thin and cannot withstand the cutting force when the cutting tool contacts the blade. The vibration not only greatly reduces the quality of the machined surface and causes visible vibration marks, but also seriously affects the machining precision, greatly wastes raw materials and machining time, slows down the production rhythm, and increases the production cost.

[0035] As Figure 1 , Figure 3 and Figure 4 shown, the pressing bolt 41 is arranged at the center of the pressing plate 4.
[0036] As Figure 5 shown, the pressing plate 4 is provided with a rubber pad 42 near one side of the vertical plate 2.
[0037] As Figure 1 and Figure 3 shown, the vertical plate 2 is provided with a groove 22 at the slot hole 21.
[0038] As Figure 1 and Figure 3 shown, the limiting rod 3 is provided with a bubble level 32.
[0039] As Figure 3 and Figure 4 shown, the base 1 is provided with a bayonet 101.
[0040] One side of the slot hole 21 is provided with a scale.
[0041] As Figure 2 and Figure 3 shown, the base 1 is provided with a triangular side plate 102 on both sides of the length direction, and the triangular side plate 102 is connected with the vertical plate 2.
[0042] Principle and operation process
[0043] The slot hole 21 arranged on both sides of the length direction of the vertical plate 2 provides flexible installation position for the limiting rod 3, and the limiting rod 3 is symmetrically arranged on both sides of the vertical plate 2 in the width direction of the base 1, and the threaded holes at both ends are threadedly connected with the fastening bolt 31. When different sizes of centrifugal blower blades need to be clamped, the fastening bolt 31 is loosened, the limiting rod 3 is adjusted in sliding along the slot hole 21, the spacing of the limiting rod 3 is adjusted, and after the limiting rod 3 is matched with the width of the blade, the fastening bolt 31 and the nut are tightened, and the limiting rod 3 is locked. It is not necessary to provide special tooling for each blade size, which greatly saves the production cost.
[0044] The groove 22 is additionally arranged at the slot hole 21 of the vertical plate 2. When the clamping force is applied to the limiting rod 3 through the fastening bolt 31, the limiting rod 3 is slightly deformed, the groove 22 provides space for the deformation of the limiting rod 3, the limiting rod 3 is deformed towards the groove 22, the contact between the limiting rod 3 and the slot hole 21 is more close and fit, the stability of the limiting rod 3 after clamping is effectively improved, the displacement deviation of the blade during the machining process due to unstable limiting is avoided, and the machining precision is effectively ensured. The scale arranged on one side of the slot hole 21 provides an intuitive reference for the operator to accurately adjust the position of the limiting rod 3. The operator moves the limiting rod 3 according to the scale value, so that the limiting rod 3 reaches the theoretical level position. At the same time, the leveling operation is further assisted by the spirit level bubble 32 arranged on the limiting rod 3. The position change of the liquid and bubbles in the spirit level bubble 32 can real-time feedback the horizontal state of the limiting rod 3, and the operator adjusts the limiting rod 3 according to the feedback, so that the limiting rod 3 is accurately leveled, and the machining error caused by the inclination of the tooling is avoided.
[0045] The pressing plate 4 is symmetrically arranged on both sides of the vertical plate 2 in the width direction of the base 1, and the pressing bolt 41 is arranged at the center of the pressing plate 4, so that the force is uniformly dispersed on both sides of the pressing plate 4 when the pressing bolt 41 is tightened. In this way, a single pressing plate 4 can clamp two blades at the same time, and the machining efficiency is higher than that of the traditional method of clamping one blade at a time. The pressing mechanism is arranged in an array on the vertical plate 2, and multiple pressing units are arranged in an array. This layout allows batch placement and clamping of blades at one time according to actual production needs, which meets the production rhythm of large-scale production. The operator only needs to sequentially complete the operation of each pressing unit, so that multiple blades can be machined at the same time, which greatly shortens the average time for machining a single blade, greatly improves the production efficiency, and meets the batch machining needs. The rubber pad 42 is attached to the side of the pressing plate 4 close to the vertical plate 2, and the rubber material is soft and has a high friction coefficient. On the one hand, the blade is inevitably impacted by cutting force during machining, and the rubber pad 42 effectively buffers and absorbs vibration energy by virtue of its elasticity, reduces the vibration amplitude of the blade, and avoids rough machining surface and size deviation caused by vibration. On the other hand, the friction between the pressing plate 4 and the blade is increased, so that the blade can be firmly “adsorbed” between the pressing plate 4 and the vertical plate 2 even if it is subjected to a large cutting force, thereby preventing the blade from being displaced under stress and ensuring the machining precision.
[0046] The triangular side plate 102 is arranged on both sides of the base 1 in the length direction and is stably connected with the vertical plate 2. During the machining of the blade, the vertical plate 2 is subjected to multiple-directional forces such as pressing force and cutting force, and is prone to deformation. The triangular side plate 102 provides additional support and reinforcement for the vertical plate 2 according to the stable structure characteristics of the triangle, disperses the stress, reasonably disperses the concentrated force, effectively reduces the deformation amount of the vertical plate 2 during the machining process, maintains the rigidity of the tooling as a whole, and ensures the machining precision is not disturbed by the deformation of the vertical plate 2.
[0047] In use, according to the width size of the blade to be processed, referring to the scale on one side of the slot hole 21 of the vertical plate 2, loosen the fastening bolt 31 manually, move the limiting rod 3 to the appropriate position, so that the distance between the limiting rod 3 and the pressing mechanism is slightly larger than the length of the blade. During operation, according to the level bubble 32 on the limiting rod 3, adjust the limiting rod 3 in combination with the scale until the bubble of the level bubble 32 is centered, indicating that the limiting rod 3 has reached the horizontal state, and finally tighten the fastening bolt 31 and the nut to lock the limiting rod 3; then place the centrifugal blower blade to be processed one by one in the clamping area surrounded by the vertical plate 2 and the limiting rod 3, and operate the pressing mechanism one by one to attach the symmetrically arranged pressing plate 4 above the blade. First, pass the pressing bolt 41 through the corresponding threaded holes of the pressing plate 4 and the vertical plate 2, and tighten the pressing bolt 41; as the bolt is tightened, the pressing plate 4 is gradually pressed down, and the rubber pad 42 is tightly attached to the surface of the blade, until the blade is firmly clamped between the pressing plate 4 and the vertical plate 2. Then the clamping tool can be clamped, the processing equipment is started to process. After processing is completed, the equipment is stopped, the pressing mechanism is operated in reverse, the wrench is used to loosen each pressing bolt 41, the pressing plate 4 is removed in turn, and the processed centrifugal blower blade is taken out.
[0048] Although the specific embodiments of the utility model have been described above in combination with the drawings, it is not a limitation on the protection scope of the utility model. Various modifications or variations made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
