This utility model discloses a flat-jaw vise with accurate positioning and high positioning precision. The lower end of the fixed jaw is fixedly installed on one end of the base, and the support of the pushing mechanism is slidably and fixedly installed on the base. The lower end of the movable jaw clamping block is slidably installed on the base, with a movable jaw fixed at one end and a mounting hole at the upper end and a threaded hole I at the lower end of the other end. A steel ball mounting groove is formed on the U-shaped groove wall near the movable jaw. The upper surface of the L-shaped angle block is provided with an inclined surface, which is placed in the U-shaped groove of the clamping block. Its lower end is slidably installed on the base, and its inclined surface presses against the steel ball. A set screw threaded into the threaded hole I of the clamping block is pressed against the end face of the L-shaped angle block away from the movable jaw. The lead screw passes through the mounting hole of the clamping block and abuts against the end face of the L-shaped angle block away from the movable jaw. This utility model has a good inclined pressing effect, accurate positioning, good stability, and high positioning precision, which can meet the needs of high-precision machining of workpieces.

The present application belongs to the technical field of stator manufacturing, and particularly relates to a stator design method for integrated general fluid machinery and a general fluid module. The stator design method for integrated general fluid machinery comprises the following steps: 1) determination of an electric drive diameter; 2) determination of an effective electric drive length; and 3) determination of a pole pitch. Through the above operation process, the operation efficiency and stability of the general fluid module applying the stator can be effectively ensured or even improved. Another object of the present application is to provide a general fluid module applying the stator design method, so that through integrated design, the intermediate connecting frame and the number of vulnerable components and friction loss are reduced, thereby further improving the overall efficiency of the unit.

The application discloses a design method and a sealing structure of a straight-through labyrinth sealing structure based on an agent model optimization and a non-uniform distribution of sealing teeth, and relates to a design method and a sealing structure of a straight-through labyrinth sealing structure. In order to solve the problems that the existing labyrinth sealing optimization depends on complex structure changes or additional components, is high in cost and is not suitable for old unit reconstruction, and a non-uniform distribution lacks a systematic design method and mechanism guidance, the design method comprises the following steps: determining design variables and constraint conditions, wherein the design variables comprise an axial total length L, a tooth number n and an axial coordinate of a middle tooth; generating sample points by using a Latin hypercube sampling; obtaining a leakage amount by CFD simulation; constructing a Kriging agent model; and optimizing by using a genetic algorithm and iteratively verifying until the accuracy is met. The application belongs to the technical field of rotary machinery sealing.
