The five-linkage-rod mechanism is a mechanism which is based on three-degree-of-freedom five-connecting-rod mechanism based on the two-spherical-hinged three-degree-of-freedom five linkage rods, controllable residence time type polishing is realized according to the traditional manual polishing characteristic design, the mechanism is suitable for various non-spherical elements, the single removal amount can be controlled at the nanometer level, and the advantages of being flexible in movement, high in reliability, high in machining quality, capable of effectively restraining medium-frequency errors and the like are achieved.

The invention discloses a laser life test fixture, which comprises a main box body, an inner box body, a support rod and a through hole. An electric telescopic rod is fixed on the top of the main box body, and the lower end of the electric telescopic rod is fixed on a fixing plate. And the lower end of the fixed plate is fixed with a spring, the movable rod and the gear are connected to each other, and the gear is fixed on the rotating rod, the end of the rotating rod is fixed with a hand wheel, and the hand wheel is connected to the bolt, and the through hole is opened On the inner box, and the bottom of the main box is fixed with a cooling fan. The laser life test fixing fixture uses two pairs of limit plates to fix the laser to prevent the laser from moving left and right. The movable rod controls the movement of multiple limit plates to fix the laser. Compared with bolt fixing, it is more convenient to use a soft rubber plate. The downward movement of the soft rubber pad causes the laser to be deformed, which can fix the laser and have a certain shock absorption effect to protect the laser from external forces.

The invention provides a preparation process of a connecting conductor material for a power source system of a new energy vehicle. The preparation process includes discharging, material strip detection, slitting, loading, polymer diffusion welding, surface treatment, punching, polishing, secondary blanking, secondary polishing, electroplating, third-time polishing, sleeving / plastic dipping, inspection, packaging, and the obtaining of the finished product. The polymer diffusion welding step includes first placing the well slit material in a jig for positioning; and a well-positioned to-be-welded material in a graphite welding area for welding. The material has the advantages of strong applicability, strong electrical conductivity, high current resistance, small resistance value and durability. The material is mainly used to connect each unit battery pack in the new energy vehicle power source system to finally form a power system of the electric vehicle.

The invention discloses a novel box type transformer station. The novel box type transformer station at least comprises a high-voltage switch chamber, a low-voltage switch chamber and a transformer chamber, wherein the high-voltage switch chamber, the low-voltage switch chamber and the transformer chamber are in echelonment distribution, and equipment lines in the high-voltage switch chamber, the low-voltage switch chamber and the transformer chamber are M-shaped, U-shaped or V-shaped. Different from the prior art, the novel box-type transformer station enables the volume of the box type transformer station to be reduced by 1 to 3 times compared to a conventional transformer station through innovative adoption of an upper-lower multilayer distribution structure, reduces the area of occupied land, facilitates transportation and decreases the transport cost; and a downward pedestal of the conventional box type transformer station does not have to be manufactured, such that the difficulty of a construction project is reduced, the cost is decreased, and unfavorable influences brought by moisture in the half-embedded pedestal to each device in the box type transformer station can be better avoided.

The invention belongs to the technical field of curtain rods, and discloses a curtain rod with self-locking function, comprising a main rod and two auxiliary rods, grooves are opened on the left and right sides of the main rod, and the two auxiliary rods are interspersed respectively In the two grooves, the inner top wall and the inner bottom wall of the two grooves are fixedly connected with tooth grooves arranged at equal distances, and two left and right tooth blocks are placed inside the two grooves. In this solution, when adjusting the length of the curtain rod, by pressing the pressing component, the pressing rod is driven to move into the groove, and then the pressing component is driven to move, and the tooth block is separated from the tooth groove, and then the auxiliary rod is pushed and pulled according to the installation requirements. Realize the adjustment of the length of the curtain rod. After the length of the auxiliary rod is determined, cancel the force on the pressing component, press the component to drive the tooth block to reset and insert it into the tooth groove again, so as to realize the self-locking of the auxiliary rod and prevent the length of the curtain rod. Secondary changes occur, the structure is ingenious, and the operation is simple.
