Description
Technical Field
The invention belongs to the field of cylinder sleeve detection equipment, and particularly relates to an online detection device for the form and position tolerance of a cylinder sleeve.
Background
The outline part and the end face of the diesel engine cylinder have strict requirements on form and position tolerance, the detection of the form and position tolerance is carried out by a three-coordinate measuring instrument, and the outer diameters of the upper and lower seat rings, the support edge and the water jacket ring are detected by an outer micrometer.

Therefore, the three-coordinate part inspection in batches usually has two defects, namely, the part inspection needs to be carried out back and forth, the distance is relatively long, and the potential hazards of collision, scratching and the like are large in the transportation, placement and operation process; secondly, the parts need to be subjected to constant temperature for at least 2 hours before detection, and the detection efficiency is low.
The form and position tolerance of the cylinder sleeve is detected in three coordinates, and generally has two forms: 1. and (4) performing hundred percent test. And (5) conveying a batch of cylinder sleeves to three-coordinate inspection, and selecting qualified parts for use. The detection form can ensure that all the delivered cylinder sleeves are qualified, but the efficiency is very low, three-coordinate resources are occupied, the waste is large, and the overall production progress of a manufacturer is influenced. 2. And (6) performing spot check. The spot check can improve the detection efficiency and avoid collision and scratch, but cannot reflect the quality states of all parts in time, so that the mass quality problem is easily caused, and the reliability of products is influenced.
When an external micrometer detects the external diameters of the upper and lower seat rings, the support edges and the water jacket ring of the cylinder sleeve, the external diameters are measured by selecting two aspects which are perpendicular to each other on a circular section, and two sets of data need to be qualified at the same time. Therefore, the detection cannot reflect the outer diameter size of the whole carrying surface, and the possible out-of-tolerance condition cannot be found in time, so that the product is mistakenly received.
