Description

Technical Field

[0001] The utility model relates to a thickness dimension measuring tool, belonging to the technical field of engine detection. Background Art

[0002] The cylinder block assembly, cylinder head assembly, crankshaft and camshaft are the four most important parts of a diesel engine. The accuracy and reliability of their mutual connection directly affect the working performance of the diesel engine.

[0003] The thickness of the cylinder block thrust surface is usually tested by a three-dimensional coordinate machine or an outside micrometer. Due to the slow detection of the three-dimensional coordinate machine and various reasons, it is not practical to require each cylinder block to be tested on the three-dimensional coordinate machine for the thickness of the cylinder block thrust surface. Therefore, in daily production, it is a common method to use an outside micrometer to test the thickness of the cylinder block thrust surface. However, due to the structural limitations of the outside micrometer, when testing the thickness of some cylinder block thrust surfaces, the outside micrometer handle interferes with the adjacent gear and ultimately fails to detect. Now there is an urgent need for a thickness dimension gauge to solve the above problems. Utility Model Content

This design solves the problem that the original device cannot detect the thickness of some cylinder block thrust surfaces due to the structural limitations of the outside micrometer, because the handle of the outside micrometer interferes with the adjacent gear and ultimately fails to detect.

[0021] As the first embodiment of the utility model: a through slot 12 is provided through the rear side of the main housing 1, a fixing plate 18 is provided through the through slot 12, a first measuring block 13 is installed at the end of the fixing plate 18, and the first measuring block 13 is provided to facilitate the cooperation with the second measuring block 14 to perform the measuring work.

[0022] The lower end of the connecting belt 20 is connected to the fixed plate 18, and a second measuring block 14 is fixedly connected to the lower part of the main housing 1. By setting the lower end of the connecting belt 20 to be connected to the fixed plate 18, it is convenient to read the descending length of the connecting belt 20 through the dial 21. A plurality of friction pads are provided on the annular side of the knob 2, and a limiting groove 3 is provided on the right side of the knob 2.

The distance between the bottom of the initial position of the first measuring block 13 and the top of the second measuring block 14 is A. When the first measuring block 13 moves to fit the top of the cylinder thrust surface, the distance is B, so the thickness of the cylinder thrust surface is AB, and the value of B can be obtained by moving the connecting belt 20 and observing the gap between the initial and final moving positions of the pointer 23 and the dial 21.
