Abstract
The invention relates to a device (1) for the insertion, guidance and evacuation of cylindrical parts to be ground in a centreless grinder (10). According to the invention, micrometric means (4, 40, 41) for adjustment of the alignment of the guides at the entry (3) to and the exit (5) from the guide chute (2) are provided and these micrometric adjustment means are independent from each other. The invention enables very precise adjustment of the alignment and prevents any shift of the parts.
Claims17
Device for the insertion, guidance and evacuation of cylindrical parts such as nuclear fuel pellets, in a centreless grinder, comprising:
- an insertion guide chute adapted to guide said cylindrical parts over the length of the grinding wheel and drive wheel of a centreless grinder,
- a first guide, called the entry guide, arranged at one longitudinal end of the guide chute and adapted to allow the insertion of cylindrical parts one by one onto the guide chute from a conveyor system on the entry side of the centreless grinder,
- mechanical means for micrometric adjustment of the entry guide relative to the guide chute,
- a second guide, called the exit guide, arranged at the other longitudinal end of the guide chute and adapted to transfer parts from the chute to a conveyor system on the exit side from the centreless grinder,
- mechanical means for micrometric adjustment of the alignment of the exit guide relative to the guide chute,
- wherein the mechanical means for micrometric adjustment of the alignment of the entry guide are independent from the micrometric alignment means of the exit guide.
Centreless grinder comprising:
- an insertion guide chute adapted to guide said cylindrical parts over the length of the grinding wheel and drive wheel of a centreless grinder,
- a first guide, called the entry guide, arranged at one longitudinal end of the guide chute and adapted to allow the insertion of cylindrical parts one by one onto the guide chute from a conveyor system on the entry side of the centreless grinder,
- mechanical means for micrometric adjustment of the entry guide relative to the guide chute,
- a second guide, called the exit guide, arranged at the other longitudinal end of the guide chute and adapted to transfer parts from the chute to a conveyor system on the exit side from the centreless grinder,
- mechanical means for micrometric adjustment of the alignment of the exit guide relative to the guide chute,
- wherein the mechanical means for micrometric adjustment of the alignment of the entry guide are independent from the micrometric alignment means of the exit guide.
Device for the insertion, guidance and evacuation of cylindrical parts such as nuclear fuel pellets, in a centreless grinder, comprising:
- an insertion guide chute adapted to guide said cylindrical parts over the length of the grinding wheel and drive wheel of a centreless grinder,
- a first guide, called the entry guide, arranged at one longitudinal end of the guide chute and adapted to allow the insertion of cylindrical parts one by one onto the guide chute from a conveyor system on the entry side of the centreless grinder,
- a first plurality of screws for micrometric adjustment of the entry guide relative to the guide chute,
- a second guide, called the exit guide, arranged at the other longitudinal end of the guide chute and adapted to transfer parts from the chute to a conveyor system on the exit side from the centreless grinder,
- a second plurality of screws for micrometric adjustment of the alignment of the exit guide relative to the guide chute,
- wherein the first plurality of screws for micrometric adjustment of the alignment of the entry guide are independent from the second plurality of screws for micrometric alignment means of the exit guide.
