Small jaw track plate and measuring method measuring frame
2014
The present invention provides a high-precision measurement of small frames and high-speed railway track plate measuring jaw. Small jaw measuring rail plate frame, comprising a T-shaped frame, a pair of fixed contacts, the prism holder in the corresponding holes in the middle of the small end of the T-rail, a screw adapter fixed to the T-rail is provided on both sides of the big end is provided small hole in the corresponding portion of the T-rail end to end, the outer cylindrical sleeve and the housing inner bore of the adapter screw fitting, the inner bore of the cam sleeve and the outer cylindrical surface with nesting of the cam the amount of eccentricity tightly against the fixed contact surface of the rail, the screw adapter bushing and the cam mechanism constituting a pair of interlocking during rotation. Geometric condition adequately simulate the rail plate of the present invention, to solve the problem of positioning mileage direction, more reliable positioning screw adapter, the interference can be mounted while the size error and the position error compensation spike caused by the hole, to ensure that the ball at the center of the prism the center of the lateral surface of the sleepers.
