A laser six-degree-of-freedom error simultaneous measurement system is characterized in that the laser emitting unit (1) is separated from the fixed sensing head (2); The sensing head (2) is connected; the moving target mirror (3) composed of light reflectors (301, 302) and half mirror (303) is arranged on the motion pair of the linear guide rail. By adopting a single polarization-maintaining optical fiber (104) to connect the laser emitting unit (1) and the fixed sensing head (2), the influence of the thermal drift of the laser on the measurement accuracy is isolated, and the volume of the instrument is reduced.

The invention discloses a wiring device between a motor and a controller. The wiring device comprises a base, a roll ball containing board, a spring mounting plate and a top board, wherein the base, the roll ball containing board, the spring mounting plate and the top board are made of insulating materials. The roll ball containing board comprises a plurality of mounting grooves and wire pressing grooves, wherein the mounting grooves are used for containing roll balls, the wire pressing grooves correspond to the mounting grooves in a one-to-one mode, and the wire pressing grooves and the mounting grooves are all independent. A baseplate is provided with conductive structures which make the mounting grooves and the wire pressing grooves be communicated in a one-to-one mode. The spring mounting plate comprises a plurality of spring mounting holes and a plurality of wire pressing holes, wherein the spring mounting holes correspond to the mounting grooves in position in a one-to-one mode, and the wire pressing holes correspond to the wire pressing grooves in position in a one-to-one mode. The roll balls are mounted in all the mounting grooves. Springs for pressing the roll balls are mounted in the spring mounting holes respectively. The top board presses the springs and is provided with bolt holes which correspond to the wire pressing holes in position in a one-to-one mode. Wire pressing bolts are mounted in all the bolt holes and all the wire pressing holes. According to the wiring device, the motor and the controller are wired quickly, the wiring part is firm, all phases of wires will not be collided, and the wiring part is neat.

Separator for steam and liquid includes exhaust pipe, mounting plate, air inlet pipe, filter, and barrel characters are that both exhaust pipe and air inlet pipe are prepared from iron pipe. Advantages are: reasonable structure, lowering production cost, no lap joint in one whole iron pipe, no welding line. Procedure for welding exhaust pipe, air inlet pipe and up barrel is changed to about 1130 deg.C furnace brazing under protective atmosphere from flame weld. Advantages of the procedure are: simplified operation technique, fine welding line, high weld strength, good air-tightness, and no pile of solder. Protection weld of CO2 gas is adopted for welding between up barrel and low barrel. Then, tube end expansion is carried out for exhaust pipe, and air inlet pipe so as to guarantee reasonable assembly technique.

The invention relates to the technical field of production line conveying, and discloses a linear conveying module and a conveying module set formed by linear conveying modules. The linear conveying module comprises a loading fixed plate, a guide assembly, a linear motor drive assembly, a base, a locating assembly and a controller. The loading fixed plate is arranged on the guide assembly. The guide assembly is arranged on the base. The linear motor drive assembly is arranged on the base. The locating assembly comprises magnetic grid reading heads and a magnetic grid. The three magnetic grid reading heads are arranged on the base and arranged at the two ends of the base and in the middle of the base. The magnetic grid is arranged on the loading fixed plate. The length of the magnetic grid is larger than the distance between every two adjacent magnetic grid reading heads. The magnetic grid reading heads and the linear motor drive assembly are connected with the controller. The linear conveying module has the beneficial effects that no cable is adopted, the structure is compact, running is smooth, the running speed is high, precise locating can be achieved, no other accessories exist, flexible combination can be achieved, and the processing takt can be shortened.

The above solution can solve the problem of charge migration between adjacent signal pins.

The invention belongs to the technical field of medical materials, and discloses a preparation method and application of a three-dimensional controllable structure multi-layer functional bracket. Put it in an oven to dry the water, then put it in a single-screw extruder for melt blending, and extrude the strip; use a three-roll calender for non-stretching cooling, and then cut it into a length of 40~ 60cm strips to obtain polylactic acid / polyethylene oxide extrudates with alternating multi-layer concentric cylindrical structure; the polylactic acid / polyethylene oxide extrudates are cut into strips with a length of 5~20mm , the stent preform is obtained through a hot pressing process, a drilling process or a winding process; the stent preform is placed in deionized water to remove the polyethylene oxide layer, and leached to obtain a multi-layer functional stent with a controllable three-dimensional structure. The method has the advantages of simple process, wide applicability, low cost, environmental friendliness, high production efficiency and wide application range of the bracket.
