The structure,location equipment,clamping device of the fixtures and connection way with the machine spindle were detailedly analyzed.

For the location of the detector of the mechanics system,the circuit of the location equipment was designed,the magnifying circuit of the sensor signal and the circuit of the serial communication were mainly designed.

The article analyzes the jig's structure,registration device,clamping device and the connection way with the machine spindle.

The paper analyzes that the shackle registration device,currently applied in the OCS,is easy to cause the accident between pantograph and OCS, and it introduces the characteristics of the structure and application of the hinge jointed anti-rise type registration device.

It introduces the design characters, construction methods, dynamic ascending of registration device, status of activated forces and inspection methods of slope of registration device, and gives the maximum values of the slope of the registration device of Re200C OCS in the circumstances of cant of outer rail in various track lines.

Analysis on the wheelset positioning device of CNC underfloor wheel lathe;

It requires a positioning device,such device can give a signal after the grade rod enters field of view,the signal can stop the runni.

An Open-loop High-precision Positioner;

In this paper the analytical design and positioner design of intensity and rigidity are described when the shock reducer and scale appliance of scale buggy ladle of ACLF finer are struck in longitudinal and cross direction.

In this paper, the intensity and rigidity of buffer and weighing unit of AC/LF finery steel buggy laddle are designed and analyzed while it bears impulse load in lengh and breadth the positioner is also designed.
