Dynamic connection, then sliding block 3-3 moves how much numerical value, the fixed grid or moving grid of capacitor grid transducer 3-2 will be moved with respect to moving grid or fixed grid
Identical numerical value is moved, obtained displacement signal is transferred to digital display instrument 4 by air plug 3-5 and handled by capacitor grid transducer 3-2, real
Show and the data of measurement are passed through into the purpose that capacitor grid transducer accurately exports, the data finally shown on digital display instrument 4 are the column
The actual (real) thickness of the friction piece of brake piece.
The preferred telescopic measuring head 1 of the present embodiment includes: telescopic measurement ring 1-1, pedestal 1-2 and survey
Measure ring reset spring 1-3, measurement ring 1-1 include: from top to bottom successively set hold ring 1-1-1, among one group ring 1-1-2 and on
1-1-3 is covered, the lower ring 1-1-1 of measurement ring 1-1 is fixedly connected with pedestal 1-2, and measurement ring 1-1 is wrapped in measurement ring reset spring 1-
Outside 3, measurement one end ring reset spring 1-3 is contacted with pedestal 1-2, and the measurement ring reset spring 1-3 other end is upper with measurement ring 1-1's
1-1-3 contact is covered, the one end connecting line 2-1 is fixedly connected with the upper cover 1-1-3 of measurement ring 1-1.The lower ring 1-1-1 of measurement ring 1-1,
Ring 1-1-2 and upper cover 1-1-3 is successively set among one group, is suitble to the measurement at the lesser position of contact surface, is suitable for train brake pad
Friction piece between gap measure the thickness of each friction piece；Using measurement ring reset spring 1-3 connection pedestal 1-2 and survey
The upper cover 1-1-3 of ring 1-1 is measured, does not have to be arduously the telescopic measuring head 1 of pressable very much in practical applications, is easy to measure.
Convex is equipped in the inner wall of the lower ring 1-1-1 and intermediate ring 1-1-2 of the preferred measurement ring 1-1 of the present embodiment
