Description
Technical Field
[0001] The utility model relates to the technical field of jigs, in particular to a jig for impeller processing. Background Art
[0002] An impeller refers to a wheel disc equipped with moving blades, which is commonly used in processes such as the transportation, pressurization, agitation, or circulation of fluids or gases. It usually consists of one or more blades rotating around an axis, and converts the kinetic energy of the fluid or gas into mechanical energy during rotation. Impellers are widely used in various industries, such as wind power generation, aerospace, the automotive industry, etc. During the impeller processing, jigs are required to ensure the stability of the impeller. The Chinese authorized utility model patent (Publication No.: CN221270894U) discloses an adjustable tooling jig for impeller processing. When this device is used, by the combined use of a blade placement seat and a fixed tooling, it can fix impeller blades of different sizes, so that during the processing, there is no need to replace the jig, improving work efficiency.
[0003] However, the above device still has the following deficiencies when in use: Since the position of the blade placement seat in the existing jig is fixed, and the blade lengths of impellers of different sizes are different, this leads to insufficient adaptability when facing impeller blades of different sizes. Specifically, when the distance is too far, it is difficult for the smaller impeller blades to overlap on the blade placement seat; when the distance is too close, it is difficult to meet the placement requirements of the larger impeller blades. Therefore, a jig for impeller processing is proposed to address the above problems. Summary of the Utility Model
[0004] The jig for impeller processing proposed by the utility model can adjust the position of the blade placement seat according to the blade lengths of different specifications of impellers, with stronger applicability.
[0005] To achieve the above objective, the utility model adopts the following technical solutions:
[0006] A jig for impeller processing includes a support frame. A moving groove is formed through the surface of the support frame. An adjusting mechanism is arranged on one side of the outer wall of the support frame. The adjusting mechanism includes a first positioning plate and a second positioning plate respectively fixed on the outer wall of the support frame. A screw rod is arranged on the first positioning plate. One end of the screw rod is rotatably connected to the second positioning plate. A movable block is threadedly connected to the screw rod. A blade placement seat is detachably connected to the movable block. The blade placement seat is located on the other side away from the outer wall of the screw rod.
[0007] Preferably, a threaded hole is formed in the movable block, and the threaded hole is in threaded cooperation with the screw rod.
[0008] Preferably, an assembly groove is formed on the outer wall of the movable block, and a pair of positioning holes are formed at the top of the movable block. The positioning holes communicate with the assembly groove.
[0009] Preferably, a connecting block is provided on the blade placement seat. The connecting block passes through the moving groove and then inserts into the assembly groove. A fastening bolt is arranged in the positioning hole. After passing through the threaded hole, the fastening bolt extends into the connecting block.
[0010] Preferably, the connecting block is in a convex shape, and a pair of holes matching the fastening bolt are provided on the connecting block.
[0011] Preferably, a through hole is penetrated on the first positioning plate, and a rocker is rotatably fitted in the through hole. The rocker is fixedly connected to the screw rod.
[0012] The utility model has the following beneficial effects:
[0013] 1. Through the structural design of the first positioning plate, the second positioning plate, the screw rod and the movable block, when using the device, the position of the blade placement seat can be adjusted according to the lengths of impeller blades of different specifications, so that the blade placement seat can better support the impeller blades, making the device more applicable and conducive to improving the processing efficiency of the impeller.
[0014] 2. Through the structural design of the connecting block, the assembly groove and the fastening bolt, after the connecting block passes through the moving groove, it can be inserted into the assembly groove for preliminary positioning, and then further positioning can be completed through the fastening bolt, making the connection operation between the blade placement seat and the adjustment mechanism simple and facilitating subsequent maintenance and replacement.
