Abstract: A machining and positioning system for aerospace irregular parts and a discrete intelligent production line therefor are provided, which relates to the field of aerospace irregular part machining. In view of the problem that complex repeated positioning and poor positioning stability is required during the transportation and processing of aerospace irregular parts, a self-positioning device, a clamping device, and a support device are used to form a follow-up clamping and positioning system for the irregular part casing, reducing complex repeated positioning. The support block of the support device can fit to the inner wall of the casing, collect the support force using piezoelectric plates, and feedback and adjust the thrust of the support block based on the magnitude of the cutting radial force, maintaining stable support of the support block for the casing and meeting production needs.

Abstract: A road network balanced drainage method aimed at reducing urban waterlogging is disclosed. According to the drainage demand, the existing intersection elevation is changed or the intersection elevation that meets the drainage requirement is designed and implemented in new construction so that the intersection drainage is distributed according to the desired proportion; the water flowing to the water accumulation position is transferred to reduce the waterlogging degree. Through the analysis of the depth of water accumulation in the whole road network, the method of water flow distribution at the intersection is used to make the precipitation flow evenly distributed in the whole road network. The method can be used for solving serious water accumulation of a certain road section, the balanced drainage of the whole road network, the technical transformation of existing intersections, and for the planned and designed roads. The method can effectively eliminate and prevent urban waterlogging.

Abstract: An intelligent seed production apparatus and method based on multistage screening and bud eye identification includes a feeding module, a pre-cutting module, a bud eye identifying and cutting module, and a material mixing module. The feeding module can screen out seed potatoes with the mass and shapes meeting the requirements through a multistage screening mechanism. The pre-cutting module can receive the seed potatoes discharged from the feeding module, and cut each seed potato in half; the bud eye identifying and cutting module can receive the seed potato pieces discharged from the pre-cutting module and determine the weight of the seed potatoes and identify the bud eye distribution on the surfaces of the seed potatoes, and cut the seed potato into multiple required tubers, so that bud eyes are distributed on different tubers uniformly. The material mixing module can receive the cut tubers, and complete the material mixing of the tubers.
