Abstract
The utility model discloses a measuring device of cylinder liner inner diameters. The measuring device comprises a cylinder and a measuring sensor. The measuring sensor is installed on an excircle of the cylinder. The cylinder is inserted into a cylinder liner. A circumference surface of the cylinder fits with an inner wall of the cylinder liner. A center of the cylinder coincides with a center of the cylinder liner. When the device performs measurement, the cylinder is inserted into the cylinder liner to compress a displacement sensor, and values of the cylinder liner inner diameters are calculated by readings of the sensor. The device is simple in structure, high in measurement accuracy, and enables online detection.
Description
Technical field
The utility model relates to engine assembling field, relates in particular to a kind of measurement mechanism of cylinder sleeve of engine internal diameter.
Background technology
Traditional approach is that slide calliper rule or feeler gauge are measured, and uses kind of calliper, because the accuracy limitations of instrument own can't satisfy high-precision measurement requirement.Measure with feeler gauge, whether qualified also can only detect, and can't accurately measure cylinder hole internal diameter size.For the cylinder bore dia more than the μ level, this measurement mechanism is very effective, and can realize online detection.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of measurement mechanism of accurate cylinder sleeve of engine internal diameter to be provided.
The utility model is achieved through the following technical solutions:
A kind of measurement mechanism of cylinder sleeve of engine internal diameter, include right cylinder and survey sensor, described survey sensor is installed on the right cylinder cylindrical, described right cylinder inserts in the cylinder sleeve of engine, cylindrical periphery and cylinder sleeve of engine inwall are fitted mutually, and cylindrical round center overlaps with the center of cylinder sleeve of engine.
Described survey sensor is displacement transducer, and displacement transducer has three.
The utility model has the advantages that: the utility model is when measuring, and right cylinder inserts cylinder sleeve inside, and the compression displacement sensor calculates the size of cylinder sleeve internal diameter by the reading that is positioned at sensor, and simple in structure, the measuring accuracy height can be realized online detection.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of measurement mechanism of cylinder sleeve of engine internal diameter, include right cylinder 1 and survey sensor 2, described survey sensor 2 is installed on right cylinder 1 cylindrical, described right cylinder 1 inserts in the cylinder sleeve of engine 3, the periphery of right cylinder 1 and cylinder sleeve of engine 3 inwalls are fitted mutually, and the round center of right cylinder 1 overlaps with the center of cylinder sleeve of engine 3.
Described survey sensor 2 is displacement transducer, and displacement transducer has three.
Claims (2)
1. the measurement mechanism of a cylinder sleeve of engine internal diameter, it is characterized in that: include right cylinder and survey sensor, described survey sensor is installed on the right cylinder cylindrical, described right cylinder inserts in the cylinder sleeve of engine, cylindrical periphery and cylinder sleeve of engine inwall are fitted mutually, and cylindrical round center overlaps with the center of cylinder sleeve of engine.
2. the measurement mechanism of cylinder sleeve of engine internal diameter according to claim 1, it is characterized in that: described survey sensor is displacement transducer, and displacement transducer has three.
