Description

one

The invention relates to devices for controlling the dimensions of parts in mechanical engineering, namely, devices for the automated control of the sizes of adjoining parts.

Devices are known for sizing the mating parts, comprising measuring stations for enveloping and grasping sizes with scale-indicating devices, such as spring-optical, and actuators.

The proposed device differs from the known ones in that the scales of the instruments are combined and equipped with an "abortion of photocells, on the upper half of which the light indicator of the measuring size measuring station is projected, and the lower half of the measuring indicator of the measuring size, and each photocell is connected when matching the light indicators.

In this embodiment, the device provides improved accuracy and productivity of selection.

The drawing schematically shows the proposed device.

It contains a measurement-size measuring station J, a dimension-sized measurement station 2, and two spring-optical indicating devices 3 installed in the stations. The scales of 4 devices are combined and equipped with a set of photocells 5. Each photocell is connected to its own electrical actuator. The station indicator light 6 / measuring the spanning size is projected onto the upper half of the scale 4 formed by the photo cells 5. The light pointer 7 of the measurement size station 2 is projected onto the bottom half of the scale. The actuators are set up so that they work if both light indicators and 7 simultaneously illuminate one photocell.

In one of the measuring stations, for example, in station 2, a part is introduced - shaft 8. Depending on its size, the light pointer 7 occupies a certain position on the scale, illuminating one of the photocells. Then, a bushing part 9 is fitted to the station 1 with the shaft 8. If the opening size of the sleeve 9 is such that the light pointer 6 appears on the same photocell as illuminated by the light pointer 7, the photocell actuator operates, the measured pair of shaft bushing is counted selected and subject to completion.

If the light pointer 6 falls on the wrong photocell that is illuminated by the pointer 7, the sleeve 9 does not mate with the shaft 5, and another sleeve is matched to it.

The accuracy of the proposed device is high, since it makes a direct comparison of the mating dimensions without using any intermediate links. In addition, the selection performance is improved, since the counting is simplified - all three indicators (covering size, covered size and their difference) are projected on one scale and the process of their comparison is automated due to the presence of executive bodies.
