The utility model discloses a plate spring support which comprises a support body used for connecting a girder and a plate spring body and a limiting assembly, the support body is provided with a side extending plate capable of supporting the bottom wall of the girder, the support body is provided with a first wall and a second wall which are arranged in parallel, and the first wall is perpendicular to the side extending plate and attached to the side wall of the girder. The limiting assembly is installed on the frame body and connected with the girder and the plate spring body. The weight of the support can be reduced while the structural strength is guaranteed, and the dead weight of the whole vehicle is reduced.

This application relates to an air-gap thermal switch and its fabrication method. The air-gap thermal switch includes: a hot-end conductor; a hot-end support shell coaxially connected to the hot-end conductor; a cold-end conductor opposite to the hot-end conductor and with a gap between them; a cold-end support shell coaxially connected to the cold-end conductor and coaxially connected to the hot-end support shell; and an adsorption pump, wherein the hot-end conductor, hot-end support shell, cold-end conductor, and cold-end support shell form a closed cavity, and the adsorption pump is connected to the closed cavity. The air-gap thermal switch of this application includes a hot-end support shell and a cold-end support shell, which shortens the processing length of a single support shell and reduces the processing difficulty of thin-walled and slender shells. During the fabrication process, it can detect whether the hot-end conductor and the cold-end conductor are in contact, improving the fabrication success rate. The welding and sealing of the hot-end support shell and the cold-end support shell are achieved by laser welding, resulting in a small heat-affected zone and minimal welding deformation, improving the coaxiality and gap accuracy after welding.

The utility model provides a mounting bracket of a dynamic vibration absorber, which is used for vibration test of a vehicle, the dynamic vibration absorber comprises a mounting hole, the mounting bracket comprises a mounting seat, a first connecting piece and a second connecting piece, and the mounting seat is provided with a mounting surface which can be rigidly and detachably bonded with a to-be-tested part of the vehicle; the first connecting piece is fixedly connected with the mounting seat, and comprises a mounting rod which is matched with the mounting hole and can penetrate through the mounting hole to extend out; and the second connecting piece is detachably connected to the mounting rod and compresses and fixes the dynamic vibration absorber on the mounting bracket. According to the utility model, the technical problem that the process of replacing the dynamic vibration absorber in a real vehicle verification stage takes a long time can be solved.

This invention discloses a composite machining equipment for aero-engine turbine guide vanes, belonging to the field of mechanical combination machining technology. It includes an integrated electrical control box and a composite machining table. The composite machining table integrates a turning unit, an electrolytic roughing unit, a drying and strengthening unit, a finish milling unit, and a closed-loop conveyor system. The closed-loop conveyor system enables precise gripping, positioning, and automatic transfer of workpieces between the various machining units. Roughing is completed by combining turning and electrolytic processes, while hot air drying combined with laser strengthening improves workpiece performance. Finish milling ensures high precision requirements. This equipment achieves integrated continuous machining of turbine guide vanes, shortening the process flow, reducing manual intervention, improving processing efficiency and quality stability, and solving the problems of dispersed processing steps and large precision fluctuations in traditional machining. It is suitable for mass production of aero-engine parts.
