Background

In the prior art, various measuring tools for measuring thickness exist, such as a ruler, a vernier caliper, a dial indicator, a gauge block and the like, when the measuring tools are used, a measured object and the measuring tools are usually held by hands, or the measured object is placed on a flat plane for measurement, but due to the fact that the two modes are not uniform in standard when the measured object is placed, or the two modes are different in holding mode, measurement errors often occur, and therefore the two modes are not suitable for accurate measurement; because in the precise measurement, a plurality of measurements are required, and the average value is finally obtained, if the measured object is displaced or inclined due to other factors in the measurement process, the measurement result will also generate errors. When the measured object is a thrust pad, the thickness to be measured is the thickness between the highest point of a spherical cushion block on the back of the thrust pad and the tungsten-gold surface of the thrust pad, the thickness is not easy to measure by using a common mechanical vernier caliper, the measurement is required by a dial indicator, but in the multiple measurement process, the thrust pad can be displaced, and the measurement precision cannot meet the requirement of parallelism error, so that the measurement error is large.

As to the utility model limit: the clamping seat is U-shaped, and one side of the clamping seat, which is used for clamping the measured object, is provided with an internal thread hole.

As a further limitation to the present invention: the adjusting piece is a bolt matched with the internal thread hole of the clamping seat, and the threaded end of the bolt faces the inside of the clamping seat.

As to the utility model discloses a further limit again: at least one gauge block is arranged.

As a further limitation to the present invention: the dial indicator is adsorbed on the flat plate through a dial indicator bracket with magnetic force at the bottom.

Since the technical scheme is used, compared with the prior art, the utility model, the beneficial effect who gains lies in:

(1) the utility model places the measured object on the flat plate of the measuring tool, and then fixes the measured object and the flat plate together through the U-shaped clamping seat, thereby preventing the measured object from displacing due to external factors in the measuring process and influencing the measuring result, and the method is favorable for accurate measurement;

(2) the utility model is provided with the bolt which can rotate upwards or downwards on one side of the U-shaped clamping seat which is contacted with the measured object, thereby being applicable to the measured objects with different thicknesses, having wider application range and strong universality;

(3) the utility model discloses a percentage table support is for magnetism to inhale the formula, can adsorb the support on the flat board, rotates the gauge outfit of percentage table wantonly and measures.

To sum up, the utility model discloses simple structure, measurement accuracy, commonality are strong, can prevent to take place the displacement by the measurand, are applicable to all adjustable thickness measurement device.
