CONTROL-SORTING AUTOMATIC DEVICE FOR MINIATURE CYLINDRICAL ASYMMETRIC PARTS Russian patent published in 2019 - IPC B07C5/08 

FIELD: control and sorting equipment.

SUBSTANCE: invention relates to control and sorting equipment in machine building and is intended for automation of control at dimensional sorting of miniature asymmetric parts of cylindrical shape, for example pins of radio connectors, in large-scale and mass production. Solving problem of control of diametral size in several preset sections with evaluation of error of shape of working part of pins of radio connectors and increased wear of feelers of tips of measuring sensors, as well as problem of low efficiency of control. Aim is achieved by the fact that the part control procedure is performed in three stages, at each of which control is performed at the specified section along the part length. At each step, the control unit actuates the control device by supplying the pickups of the sensor to the monitored part. One of the measuring probes of each sensor is made in the form of a flat disc, and the second one – in the form of a knife. After time for control, pickups of pickups of the sensor from the controlled part are removed with transfer of the measurement result to the measuring unit. Based on the three-stage data control results, the measurement unit generates, together with the control unit, a command for the corresponding pneumatic cylinder for unloading the part from the holder into the required receiving device with suitable parts, correctable or unrecoverable defects. Holder of parts is made in the form of two levers, fixed with common axis of rotation, wherein one of levers is fixed, and second is rotated by means of pneumatic cylinder by specified angle, releasing controlled part.

EFFECT: as a result, by the end of the measurement, the diametric size is checked in several sections on the working length of the part with evaluation of the shape error.
