The invention discloses a resistance welding process of a fluid reservoir of a compressor. The resistance welding process of the fluid reservoir of the compressor is used for projection welding synchronous rings of an upper case body of the fluid reservoir, a steel tube and a copper tube and connecting a lower case body of the fluid reservoir in a seal welding. The resistance welding process comprises the following steps that: S1, welding end of the steel tube is cold pressed in the shape of a horn; S2, welding end of the copper tube is cold pressed in the shape of a convex ring and inserted into the horn-shaped welding end of the steel tube; S3, the copper tube contacts with the end face of the horn-shaped welding end of the steel tube before welding and a gap is formed between the copper tube and the inner side of the horn-shaped welding end of the steel tube, a line contact is formed between the steel tube and the fluid reservoir of the compressor to suspend the steel tube inside the upper case body of the fluid reservoir; S4, pressure is exerted on working parts by medium-frequency direct-current resistance ring projection welding to discharge and fusion weld the copper tube and the steel tube and the steel tube and the upper case body, and to seal weld the upper case body and the lower case body by resistance seam welding. The resistance welding process is capable of welding the fluid reservoir, downsizing working space, saving technological process and solder, reducing cost and meeting structural requirements of the fluid reservoir with the steel tube inside and the copper tube outside.

The invention discloses a keyway processing equipment for antique buildings, which includes a frame, a rotating seat is fixedly connected to one side of the top of the frame, and a rotating disc is connected to the top of the rotating seat, and the outer sides of the rotating disc are equidistantly arranged. There is a guide groove, the middle part of the guide groove is rotatably connected with a fixed frame, the front shaft of the fixed frame is fixedly connected with a gear, the surface of the gear is meshed with a gear ring, the guide frame is distributed in a cross, and each Angles correspond to one station, two stations, three stations and four stations. The invention relates to the technical field of wood processing. This kind of keyway processing equipment for antique buildings solves the problem that the current processing of keyways for antique buildings generally adopts step-by-step processing. Multi-equipment combined processing requires a large space and high equipment cost, which is not conducive to the processing and use of small and medium-sized enterprises.

The invention discloses a radar correlated imaging method of a single transmitting system, comprising the following steps: the size of a meta-material reflective plate and the spacing, number and arrangement shape of scattering units are acquired; an arrangement mode of the scattering units maximizing the distribution detection precision is acquired; a simulation analysis is made of the meta-material reflective plate using HFSS software, and a meta-material modulation reflective plate is designed to realize radar correlated imaging of a single transmitting antenna; an electromagnetic wave signal transmitted by a transmitting antenna is randomly modulated by the modulation reflective plate and irradiated on an imaging target, and after the electromagnetic wave signal is scattered by the target, scattering echo is received by a receiving antenna; and a data processor processes a calculated radiation field and the received scattering echo to get an image of the target. Based on radar correlated imaging of a single transmitting antenna, a target can be imaged at high quality, at high resolution and at a long distance. The complexity and cost of the transmitting system are reduced. Correlated imaging radar is enabled to have functions of target tracking and measuring simultaneously while the detection distance is ensured.
