DIMENSIONCQNTROL.

Series 8203

The system DIMENSION CONTROL Series 8203 is used for the quality inspection of bearing bushes. With a cycle time of just four seconds, the bearing bushes are inspected without contact for external and internal diameters as well as coaxial properties and they are also marked for optimum installation. The measurement system operates in a production centre and is designed for 100% industrial sampling inspection.

Measurement technique

To find the external diameter three sensors are arranged at each end of the bush at an angle of 120° to one another. The sensors have a measurement range of 0.5 mm To acquire the internal diameter two capacitive sensors are integrated into a pin. Both sensors are positioned precisely opposite a pair of external sensors. The coaxial properties of the bush are determined from the measured wall thickness using this configuration.

To achieve a high throughput, the system operates with two measuring stations. One station consists of a separator device, an air-bearing block and a frequency drive motor. The bearing bushes are passed from the oscillating conveyor specifications to the measuring station in the correct orientation via a separating device. The measuring head alternates pneumatically between the two measuring stations. The measurement occurs without making contact. The linearity characteristics of the sensors are optimized in the analyse software such that almost an ideal sensor is provided. Based on the inspected features, the bushes are marked with an ink jet and then sorted.

System advantages

- Dynamic measurement with highest accuracy

- No wear due to non-contact measurement

- Highest precision due to rotational movement on air professional bearings

- High cycle rate due to pipeline processing

- Marking of the optimum professional fitting orientation

- Sorting according to quality classes.
