Centering and clamping device

摘要

A centering and clamping device has a housing (1) with a drive mechanism (2) situated in its interior for actuating a clamping hook (5). The clamping hook (5) is active outside the housing (1). The clamping hook (5) engages a seal element (3) that is positioned in an opening (4) on the housing (1). The seal element (3) has a passage opening (6) for receiving the clamping hook (5). The passage opening (6) fits exactly with the clamping hook (5) in every position. The seal element (3) is mounted so that it is rotatable in the opening (4) of the housing (1). A portion of the sealing element projects, at all times, outside of the housing (1) so that the opening (4) of the housing (1) is completely closed in every rotation position of the seal element (3).

主权项

1. A centering and clamping device comprising:
a housing having an opening for receiving a seal, the opening defined by an arcuate wall, a drive mechanism is coupled with the housing; a clamping hook active outside the housing is actuated by the drive mechanism, the hook mechanism engages a seal element positioned in the opening on the housing; the seal element includes a passage opening for receiving the clamping hook, the opening axially extending through the seal, the passage opening fits exactly with the clamping hook in every position, the seal is mounted so that it is rotatable in the opening of the housing, the seal includes a portion projecting from the housing at all times such that the opening of the housing is completely closed in every rotational position of the seal element and devoid of wiper seals on the seal element and the clamping hook extending from the seal with a peripheral configuration so that the clamping hook moving through the seal is axially continuous and in constant contact with the passage opening so that the passage opening is devoid of a seal contacting the clamping hook.
