Description

technical field [0001] The invention relates to an intelligent industrial robot device for assembling an automobile water pump impeller in the technical field of automobile parts assembly equipment. Background technique [0002] The automobile water pump is the main component of the automobile engine cooling system. Its function is to force the coolant in the engine to circulate in the cooling system and reduce the impact of high temperature on the engine during engine operation. Automotive water pumps are generally composed of water pump housings, connecting plates, shaft-connected bearings, water seals, impellers, etc. [0003] The impeller is the core of the pump work. When the pump is working, the impeller rotates under the drive of the pump shaft. Due to the action of the blades, the liquid in the pump produces very complicated movements. On the one hand, the liquid moves with the rotation of the impeller. The pump is constantly thrown out from the rotating impeller, t...

Problems solved by technology

[0004] The key point of the assembly process of the impeller is to ensure that the axial centerline of the impeller is aligned with the assembly hole. If the impeller is pressed and installed tilted, an unbalanced load will be generated, resulting in abnormal wear or even damage to the impeller.

The impeller of the water pump and the shaft-connected bearing of the water pump are interference fit, and are pressed by a hydraulic or pneumatic press. In order to monitor the press-fit situation, there is usually a pressure monitoring instrument on the equipment. Automatic alarm, indicating that the press-fitting force is abnormal. This situation may be due to too much press-fitting interference, or the impeller is tilted during the press-fitting process. However, due to the large pressure setting range of this method and the equipment pressure detection Precision and other issues are difficult to find for general press-fit deviation equipment. In actual production, the press-fit interference is guaranteed by the machining accuracy of the impeller, and the press-fit alignment is guaranteed by tooling fixtures

[0005] Although those skilled in the art have designed and manufactured an automatic device for impeller press-fitting, it is not ideal

The automatic impeller press-fitting devices are all special-purpose equipment, and the six-degree-of-freedom industrial robot is not used, resulting in poor flexibility and poor adaptability of the impeller automatic press-fitting device. For new types of pumps, existing equipment needs to be rebuilt or newly purchased.

[0006] In the patent application, the automatic assembly function of the impeller of the automobile water pump can also be completed, but the industrial robot is not used in the design plan, and its positioning and press-fitting mechanisms are all in the form of a special machine, which can only correspond to a specific type of water pump

There are two problems in this patent application. First, it is difficult to adjust the process parameters. Once a relatively large process adjustment is required, such as increasing the pressure and changing the depth of the press, the special machine equipment may not be able to respond, and a large-scale equipment transformation must be carried out, resulting in Long-term equipment outage and high transformation costs. Secondly, this patent does not have expansion functions. Once a new type of water pump appears, the special machine equipment will not be able to cope. It may be necessary to re-purchase similar equipment, resulting in increased investment and utilization of production area. low rate

[0007] The above-mentioned problems still exist in the prior art, and it is impossible to meet the market demand of multiple varieties, small batches, and short beats. Therefore, the research and development of an intelligent industrial robot device for assembly of automobile water pump impellers has always been an urgent subject to be solved.
